Penguin poop helps form clouds over Antarctica, potentially cooling it
In Antarctica, penguin poop, or guano, can cover the ground for miles, especially around penguin colonies with thousands of individuals. In fact, large, brown guano stains on Antarctica’s white ice have even helped scientists discover new penguin colonies from space. A recent study now finds that the massive amounts of guano play a critical role: […]
Gelada monkey vocalizations offer insight into human evolution: Study
With their bright red, hairless chests and grass-grazing lifestyle, gelada monkeys are quite unusual. They are the only primate, other than humans, to primarily live on land instead of in trees, and a new study shows they are also able to detect emotional and social cues through vocal exchanges. “Geladas are special because they live […]
New method can detect nearly every coral genus in Japan from water samples
- Environmental DNA (eDNA) coral research involves analyzing water samples to identify corals based on the DNA that they secrete into the water, largely via their mucus.
- eDNA research on corals can help scientists understand the changes wrought by global warming and marine pollution by providing coral identification data faster and in some cases more accurately than visual surveys by scientists.
- A team of marine scientists based in Japan, an archipelagic nation with a high level of coral biodiversity, has used an eDNA method to develop a system that can detect nearly all of the country’s 85 reef-building coral genera; no other research group in the world has achieved the same level of detection accuracy and coverage for corals using eDNA.
- They released their findings in a study published on May 22.
Female bonobos wield power through unity: Study
Male bonobos are larger and stronger than females, so researchers have found it puzzling that the female apes enjoy high status in bonobo society. After analyzing three decades of behavioral data, researchers recently shared a study that pinpoints their source of power: female alliances and coalitions. “Only [among] bonobos, females form coalitions to gain power […]

An alternative approach to bridge Indigenous knowledge and Western science for conservation (commentary)
- The idea of integrating Indigenous and Western knowledge systems is often well-intentioned, but ultimately misguided, write the authors of a new commentary who were part of a project for WCS Canada and the Tr’ondëk Hwëch’in First Nation in the Yukon.
- Their new study offers an alternative approach, in which these knowledge systems can exist independently and simultaneously, without seeking to control or validate one another.
- “It is our hope that this work sparks a greater conversation about land-use planning across Canada, in pursuit of a world where wildlife and people can thrive in healthy and valued lands and seas,” the authors write.
- This article is a commentary. The views expressed are those of the authors, not necessarily Mongabay.
Vortex predator: Study reveals the fluid dynamics of flamingo feeding
Flamingos, often pictured standing still with their heads submerged in water, make for a pretty picture. But peep underwater, and you’ll find the tall, elegant pink birds bobbing their heads, chattering their beaks, and creating mini tornados to efficiently guide microscopic prey into their mouths, according to a new study. “Think of spiders, which produce […]
Antibiotic pollution widespread in world’s rivers, study finds
Nearly a third of all antibiotics that people consume end up in the world’s rivers, a new study finds.

Sumatran tiger protection needs more patrols, tougher penalties, study finds
- A new study on Sumatran tiger conservation in Indonesia’s Gunung Leuser National Park underscores that poaching remains the top threat, despite extensive patrols and antitrafficking efforts over the past decade.
- Researchers found that while patrols removed hundreds of snares and law enforcement increasingly pursued criminal charges, poaching rates remained high and tiger populations continued to decline in some areas.
- Despite stricter conservation laws and improved prosecution rates, the financial rewards of poaching still outweigh the penalties, limiting the deterrent effect on poachers and traffickers.
- The study recommends increasing patrols in high-risk areas, improving community engagement in law enforcement, and providing alternative livelihoods to reduce the economic lure of poaching.
Singapore study says roadside flowers can improve urban butterfly biodiversity
Narrow strips of flowering plants along road edges can support high butterfly diversity, a recent study from Singapore has found.

Ronan the sea lion outperforms humans at keeping a steady beat, study finds
A sea lion named Ronan is better able to keep a beat than the average human, a new study finds. Such ability in animals is generally thought to be unique to humans and some birds, but Ronan’s performance challenges those assumptions, the study’s researchers say. Ronan, a California sea lion (Zalophus californianus), was born in […]
‘De-extinction’ isn’t just misleading — it’s dangerous, ecologist says
A biotech company in the United States made headlines last month by revealing photos of genetically modified gray wolves, calling them “dire wolves,” a species that hasn’t existed for more than 10,000 years. Colossal Biosciences edited 14 genes among billions of base pairs in gray wolf DNA to arrive at the pups that were shown, […]
PHOTO ESSAY Wind-blown sand scouring life off a Southern African landscape
- Botany professor emeritus Timm Hoffman and his colleagues are seeing eddies of dune sand piling up around quiver trees at study sites in northwestern South Africa.
- Hoffman has been studying the iconic trees for 20 years — the sand, which in places has formed drifts up to 2 meters (6.6 feet) deep, is new.
- Five years ago, environmental scientists noted an increase in wind-blown sand plumes in the arid areas on both sides of the South Africa border for reasons that are not entirely clear.
- This spreading sand is killing off the succulent vegetation adapted to this climate, threatening this austerely beautiful region’s biodiversity and the livelihoods of shepherds and farmers who call it home.
Listening to whales is key to their conservation
Biological oceanographer John Ryan joins Mongabay’s podcast to discuss his team’s multiyear study that examined vocalizations of baleen whales, including blue (Balaenoptera musculus), humpback (Megaptera novaeangliae) and fin whales (Balaenoptera physalus), and how this science is critical for understanding their feeding habits, and thus informing their conservation. The study found that these whales’ songs rise […]

Yet, these elders — fish that spawn in abundance, coral that shelters marine life, or elephants that guide their herds […]
Loss of great white sharks triggers domino effect down food chain, study shows
- A new study shows how the disappearance of an apex predator, the great white shark, from South Africa’s False Bay triggered changes throughout the food chain.
- With the loss of the top predator in the area, populations of its prey species, such as fur seals and sevengill sharks, increased; the latter’s prey, meanwhile, small fish and smaller benthic sharks, declined.
- The changes also coincided with shifts in the behavior of animals that live in the orbit of great whites.
- Over a 20-year period, the authors observed a significant drop in numbers of great white sharks beyond the study area, raising concern that the overall population of the protected species might be in decline.
Why captive elephants formed a circle during the San Diego earthquake

Traffic noise turns Galápagos warblers into angry birds
Traffic noise isn’t just unpleasant; in the Galápagos Islands, it can also make songbirds aggressive, a recent study has found. Once famed for their undisturbed natural ecosystems, the Galápagos Islands have seen a rise in road infrastructure and traffic in recent decades. Researchers wanted to understand how birds react to the increased noise. So they […]
Ground-level ozone pollution poses growing threat to planetary health
- In the stratosphere, ozone acts as a protective layer. But in the troposphere, at ground level, this colorless gas is incredibly harmful to human health and the environment in ways scientists are still working to fully understand. The problem exists worldwide, but may become especially bad in tropical nations this century.
- Ground-level ozone is a major air pollutant that shortens human lives and kills thousands each year, resulting in major economic impacts. It is formed when methane, nitrogen oxides and volatile organic compounds (released from vehicles, industry, power plants and crops) react in the presence of sunlight.
- Climate change worsens tropospheric ozone, with higher temperatures accelerating the chemical reaction that creates it, and because stalled weather systems (especially heat domes) allow buildup of ozone in stagnant polluted air. Ozone pollution not only impacts urban area, but also rural agricultural areas.
- Ozone impacts on biodiversity are significant and growing — harming pollinators, reducing crop yields and limiting forest growth, with global implications for food security and humanity’s reliance on forests as carbon sinks. Effectively tackling climate change and reducing ozone precursors are major solutions.

Colombia’s coffee farmers try to balance innovation and tradition to adapt to climate change
- Researchers and coffee farmers in Colombia are trying to find strategies to adapt to unpredictable weather, rising temperatures and erratic rainfall, which are disrupting Colombia’s coffee industry by fueling pests and diseases like the coffee berry borer and coffee leaf rust.
- Cenicafé, the national coffee research center, is continuously developing new hybrid coffee varieties that are resistant to diseases and climate change for farmers, but pests are evolving, requiring more research and genetic diversification.
- Some farmers are restoring the much slower traditional shade-grown coffee practices through reforestation and agroforestry, which help them access premium high-end coffee markets while tackling and adapting to climate change.
- With the limited options presented, some researchers say coffee growers must at times choose between high-yield hybrids or eco-friendly organic farming, weighing sustainability against economic survival.
For wandering elephants, path of least resistance could help map out safe corridors
A new study reveals how African elephants plan their elaborate journeys: they strategically choose the least energy-consuming routes to reach food sources. These findings, researchers say, can help conservationists design elephant corridors to connect fragmented habitats. African savanna elephants (Loxodonta africana), considered endangered, can travel vast distances for water, food or mates. Some landscapes they […]

Polar sea ice continues steep decline; but will a troubled world notice?
- Polar sea ice has reached record, and near-record, lows for this time of year, pushing the pace of global warming and alarming scientists. The just declared 2025 Arctic sea ice extent winter maximum is the lowest on record, at 14.33 million km² (5.53 million mi²). That’s 80,000 km² (31,000 mi²) below the previous low seen on March 7, 2017.
- The 2025 Antarctic sea ice extent summer minimum on March 1 tied for the second lowest on record, at 1.98 million km² (764,000 million mi²). The all time record Antarctic summer low was 1.79 million km² (691,000 million mi²) reached on February 21, 2023. Polar ice satellite records have been continuous since 1979.
- Sea ice loss is expected to continue its slide based on climate models, with scientists warning that the Arctic landscape is likely to be transformed beyond recognition within decades. Sweeping changes will devastate Indigenous polar communities, disrupt Arctic ecosystems, and ultimately lead to the demise of iconic polar wildlife.
- Inhospitable polar conditions continue challenging scientists’ ability to gather data and make precise polar forecasts vital for knowing our climate future. But it may be even more challenging to raise public awareness and political will to reduce carbon emissions and reverse polar ice loss before it passes dangerous tipping points.
Researchers find new killifish species in Kenya
- According to a new study, a new species of killifish, Nothobranchius sylvaticus, has been found in seasonal swamps in the ephemeral marshes of Kenya’s historic Gongoni Forest at the coast.
- Scientists from Canada, France, Kenya and South Africa report that the severely restricted habitat of the seasonal Mkurumudzi River in southeastern coastal Kenya is threatening the survival of the fish species.
- The killifish, a unique species with iridescent blue scales, red markings and vibrant fins, has been deposited at the National Museums of Kenya and the Royal Museum for Central Africa.
- An expert is calling for the formal designation of the Gongoni Forest as a key biodiversity area and local communities’ engagement to protect the small freshwater fish, ensuring its recovery and avoiding threats.

Cardiovascular […]
With climate change, cryosphere melt scales up as a threat to planetary health
- Earth’s cryosphere — comprised of ice sheets, glaciers, permafrost and snowfall — is in a rapid state of flux due to escalating climate change, with numerous studies underlining the grave risks posed by the thaw.
- Today, that worldwide meltdown poses new threats to human lives — endangering freshwater supplies and food security while increasing the risks of natural disasters and disease outbreaks. Cryosphere loss poses immense dangers to the environment, agriculture, economy and society according to a new report.
- If emissions continue unabated, these problems will only worsen. Scientists warn of compounding risks as cryosphere melt escalates, including sea level rise, the slowing of ocean currents, and the triggering of feedbacks that will add to climate change.
- 2025 is designated the International Year of Glaciers’ Preservation. Experts are calling for drastic cuts to carbon emissions because each fraction of a degree of warming avoided counts toward the preservation of the cryosphere along with the ecosystem services that ice, snow and permafrost provide.

For this study, researchers wanted to understand overall butterfly population trends across the U.S. They gathered records of 12.6 million individual butterflies across […]
Breast milk contamination exposes Africa’s ‘forever chemicals’ problem
- Researchers warn that synthetic chemicals in various products, including carpets, clothes, furniture, adhesives, food packaging, and nonstick cookware, pose a significant threat to infants in Africa.
- Over the past two decades, the chemicals, known as per- and polyfluoroalkyl substances (PFAS), or “forever chemicals,” have become a significant public health concern in Europe and North America. Emerging data from African countries point to the pervasive nature of the problem in the continent.
- PFAS exposure is linked to liver damage, thyroid diseases, cancer, and reproductive health problems, and can be especially dangerous for infants and children, experts say.
- Countries like the U.S. are beginning to pass laws to control PFAS levels in drinking water systems. Still, regulations that target PFAS are “rare across African countries,” a recent study notes.

As global genetic diversity declines, conservation efforts offer some hope
Genetic diversity within many species is declining globally, according to a recently published study. “Any threat that reduces the size of a population, or which causes a larger population to become fragmented into two or more smaller populations, can cause a loss of genetic diversity,” lead researcher Catherine Grueber, from the Conservation Genetics Specialist Group […]
Leopards’ unique ‘sawing’ sounds could aid conservation efforts
- Leopards frequently make a distinctive, deep, guttural roar that is sometimes called “sawing” because it sounds like someone manually cutting wood.
- In a study published in the journal of Remote Sensing in Ecology and Conservation, researchers discovered that by examining these sounds using a method called bioacoustics, they can monitor far wider areas.
- In Tanzania’s Nyerere National Park, the team used a camera trap and autonomous recordings to survey large African carnivores. They were able to identify individual leopards by their vocalizations with up to 93% accuracy.
- According to a specialist who was not involved in the study, identifying and tracking leopards by their roars demonstrates how cutting-edge concepts and tools can be used to unearth intriguing new information about the natural world.
Explosive ‘bomb cyclone’ pummels Europe, hitting UK hardest

Do cheetahs scavenge? Yes, research says, but also not really
- Recently published research finds that cheetahs aren’t above scavenging other predators’ kills, contrary to the conventional wisdom that they only eat what they kill.
- Direct observations and by-catch data from carnivore research projects in three locations in South Africa and Malawi were used to gather information on cheetah scavenging.
- The researchers say that understanding these behavioral shifts is crucial for cheetah conservation, as successful reintroduction efforts depend on the ability of cheetahs to adapt to new environments and food acquisition strategies.
- However, other cheetah experts question how common this phenomenon is, given that the researchers only recorded three scavenging events between 2019 and 2023.
Scientists are tracking global wildlife’s contributions to humanity
- New research assesses in detail the contributions of wildlife to people.
- Humanity relies on an array of ecosystem services for well-being and survival, but the provision of these services rely not just on vegetation but also the wild animals that inhabit the same ecosystems.
- They found that vertebrate wildlife on land and in freshwater and marine environments support 12 of the 18 categories of nature’s contributions to people set forth by the U.N.’s Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services.
- The authors say that accounting for wildlife along with measures of ecosystems such as vegetation cover will provide a more complete picture of their health and help guide decision-making aiming to ensure that those ecosystems continue to provide critical services to people.

Next-gen geothermal offers circular promise, but needs care and caution
- Enhanced geothermal systems (EGS) and other next-generation geothermal tech show promise as a relatively clean, reliable renewable energy source for a post-fossil fuels future.
- Next-gen geothermal uses a variety of engineering techniques, including hydraulic fracturing borrowed from the oil and gas drilling industry, to create conditions for successful subsurface energy production beyond traditional locations, such as hot springs.
- Enhanced geothermal’s promise of a reliable source of power is huge around the globe, but so far has barely been tapped, say experts. Companies are starting to develop commercial-scale projects, aiming to harness this potential.
- But next-gen geothermal is not without risk. There are concerns, for example, that this tech can induce seismicity. In the past decade, earthquakes shut down two EGS projects in South Korea and Switzerland. Yet, experts say this concern and other environmental impacts, such as pollution, can be controlled and mitigated.
Armed conflict, not Batwa people, at heart of Grauer’s gorillas’ past decline in DRC park
- The decline in critically endangered Grauer’s gorillas between 1994 and 2003 in the highland sector of Kahuzi-Biega National Park in the Democratic Republic of Congo was due to the impacts of armed conflict, rather than the presence or absence of Indigenous communities, according to a new study.
- The finding, including recent analysis of forest loss in parts of the park where Indigenous Batwa people returned, challenges simple but competing narratives that the region’s Batwa people are either forest destroyers or forest guardians, say various primatologists.
- After the onset of the Rwandan genocide and Congo Wars, which drove an influx of refugees, poaching, hunting and mining in the region, estimates of Grauer’s gorillas dropped from about 258 to 130 individuals, only to rise again once the Second Congo War ended.
- Researchers and conservation authorities say conservation in Kahuzi-Biega National Park remains challenging, but that Indigenous people should be included in environmental stewardship.

Orcas, or killer whales, are the apex predator in the ocean when they work together. A new study documents how a pod of orcas is able to hunt and kill the largest fish in the world, the whale shark (Rhincodon typus), which can be twice the size of an individual orca (Orcinus orca), though the […]
Camera traps, drones meant for wildlife can ‘spy’ on women: Study
Technologies like camera traps and drones have made monitoring wildlife in forests easier than ever. However, a new study has found that in a protected area in northern India, these devices also end up watching and harassing women who use those forest spaces. “These findings have caused quite a stir amongst the conservation community,” Chris […]
‘Old’ animals offer wisdom and stability, need protection: Study
In many animal societies, elderly individuals are critical contributors to their species’ survival, a new study has found. That’s why wildlife conservation must account for older animals, researchers say. Keller Kopf, lead author and ecologist at Charles Darwin University, Australia, told Mongabay he wanted to counter the idea that “getting old is always a bad […]
Slender-billed curlew, a bird last photographed in 1995, is likely extinct
For decades, the slender-billed curlew, a grayish-brown migratory wetland bird with a long, arched bill, has evaded detection, prompting speculation about whether the species is still out there. Now, a new study has confirmed that the species is indeed most likely extinct. “Speaking personally it’s a source of deep sadness,” Geoff Hilton, conservation scientist at […]
Shipping emissions reduction sheds light on marine cloud geoengineering
- Unprecedented marine heat waves in the North Atlantic have been driven in part by a recent drop in shipping emissions, leading to a reduction in highly reflective marine clouds that had previously masked some of the warming from humanity’s greenhouse gas emissions, studies find.
- New limits on sulfur dioxide emissions from shipping, introduced by the International Maritime Organization in 2020, created an inadvertent “natural experiment” that is helping to improve models of the interaction between atmospheric aerosols, clouds and climate.
- The sulfur dioxide emissions reduction also provides the clearest test to date of marine cloud brightening (MCB) — a controversial geoengineering approach proposed to mitigate climate change. It shows that to be effective and avoid a dangerous termination shock, MCB would need to be continuous and sustained.
- Reducing atmospheric aerosol pollution has major benefits for human health, but will also inevitably lead to an unmasking of more dangerous climate warming. This means that improvements in air quality must simultaneously be coupled with decarbonization, experts say.
African elephants declining — but some areas show promise
Across the African continent, elephant populations have largely declined over the past several decades, but some areas show hopeful signs of recovery, according to a new study. Researchers have monitored the numbers of forest and savanna elephants (Loxodonta cyclotis, L. africana) in different parts of Africa since the 1960s. However, few studies have compiled all […]
Animals consume alcohol more often than previously known: Study
What’s new: Humans know a thing or two about drinking alcohol, but accounts of animals turning to booze have often been discounted as accidental, unnatural or rare. Researchers now argue in a new study that animals drinking alcohol, or more specifically ethanol, might be more commonplace in the natural world than previously thought. “We’re moving […]
At least 146 dead in back-to-back tropical cyclones in Philippines
Two tropical cyclones recently struck the Philippines one after the other, leaving at least 146 people dead, according to government reports. The country first felt the peak intensity of Severe Tropical Storm Trami (local name Kristine) on Oct. 24. The storm maintained sustained winds of up to 95 kilometers per hour (59 miles per hour) […]
Calls for caution as enhanced rock weathering shows carbon capture promise
- Natural rock weathering is a fundamental part of Earth’s carbon cycle but occurs over thousands of years. Enhancing this cycle by spreading fine volcanic rock on agricultural land is a form of geoengineering that could speed up this process and permanently lock away carbon dioxide within decades.
- Startups and research programs are underway across the globe to explore the effectiveness and risks of this climate solution. Spreading rocks such as basalt can sequester carbon and benefit soils, with some studies showing crop yield increases.
- If scaled up, enhanced rock weathering could store gigaton levels of carbon in the future, according to early research. But myriad challenges and uncertainties remain, not least of which is how to accurately calculate and verify how much carbon is being stored, and for how long.
- Some companies are already pushing ahead with deployment, with the idea of profiting from carbon credits, but experts caution that long-term studies are needed to ensure the technique’s efficacy, sustainability and environmental safety.
Researchers track koalas using innovative airborne DNA detection tool
What’s new: Researchers have successfully detected the presence of koalas and other threatened wildlife species using new tools that allow easy collection of airborne environmental DNA, according to a recent study. What the study says: It’s often difficult, time-consuming and expensive to collect data and observe threatened wildlife like koalas (Phascolarctos cinereus), small marsupials that […]
Australia’s Global ‘Nature Positive’ Summit features Indigenous voices, but little government action
SYDNEY – Just prior to the COP16 biodiversity summit in Colombia, the Australian Government hosted the world’s first Global ‘Nature Positive’ Summit. ‘Nature positive’ means “an improvement in the diversity, abundance, resilience, and integrity of ecosystems from a baseline” according to Australia’s Environmental Protection and Biodiversity Conservation Act (EPBC) and is a key part of […]

As 25 Earth vital signs worsen, scientists warn of ‘irreversible climate disaster’
- Earth is inching closer to irreversible climate change according to a recent report by an international group of climate researchers and Earth System scientists.
- Tracking 35 planetary vital signs — used to gauge Earth’s response to human activities — researchers found 25 are at record risk levels, including greenhouse gas concentrations, fossil fuel consumption, rising temperatures, forest loss, and biodiversity decline.
- The authors underline the immediate need for wide-ranging climate action to rein in fossil fuel use and control emissions, alongside other measures to stave off a deepening climate crisis. “We are on the brink of an irreversible climate disaster,” they wrote.
Climate change is turning Antarctica green, but not in a good way: study
What’s new: A recent study reveals that the icy Antarctic Peninsula, the northernmost part of mainland Antarctica, has experienced a nearly twelve-fold increase in plant cover over the last 35 years. The greening, driven primarily by the spread of mosses, has accelerated notably since 2016, researchers found. “The landscape is still almost entirely dominated by […]
Controversial US marine geoengineering test delayed until next year
- The first-ever field test of ocean alkalinity enhancement in the United States was pushed back to 2025 due to shipping issues. But the geoengineering experiment has also run into public opposition from local environmentalists, commercial fishers and others.
- The test would dump sodium hydroxide (commonly called lye) off the New England coast to study its dispersal as a potential tool for sequestering CO₂.
- Opponents allege this small-scale geoengineering test could harm local wildlife, but researchers say the material will disperse within minutes.
- The scientists say they will also continue to reach out to local communities to alleviate fears over the study.
High CO2 levels are greening the world’s drylands, but is that good news?
The increased concentration of CO2 in the atmosphere since pre-industrial times isn’t just driving climate change — it’s also making much of the world’s drylands greener with increased plant growth. This is known as the CO2 fertilization effect, and politicians sometimes cite it to rhetorically downplay the negative global impacts of climate change, saying it’s […]
People hugely underestimate carbon footprint of the wealthy, study shows
A recent study reveals that the majority of people, regardless of how much they earn, greatly underestimate the personal carbon footprint of the richest members of their society, while overestimating that of the poorest. This suggests that “most people, including the wealthiest, are largely unaware of the profound inequality in personal carbon footprints within their […]
Arctic sea ice hits summer minimum; Antarctic hovers at new winter lows
- The Antarctic winter sea ice maximum is on track to be the second lowest on record, at 17.15 million square km² (6.62 million mi²), close to the 2023 record low of 16.96 million km² (6.55 million mi²). Some scientists see this as anomalous. Others see it as a shift in the southern polar environment, maybe triggered by climate change.
- The Arctic summer sea ice minimum also stayed low this year, at 4.28 million km² (1.65 million mi²), making it the 7th lowest minimum in the satellite record. So far, 2012 saw the record minimum of 3.41 million km² (1.32 million mi²).
- Polar sea ice losses have global impacts. In one analysis, researchers estimated the planetary cooling effects of Arctic and Antarctic sea ice during 2016-2023 were about 20% and 12% less, respectively, than they were during 1980-1988, leading to almost 15% less cooling power for the planet.
- With about 12% declines of Arctic Ocean ice each decade, researchers predict a nearly ice-free Arctic summer by 2050, allowing more shipping through the Northwest Passage but threatening this unique polar ecosystem. Studies also show the Antarctic ice sheet to be increasingly at risk, particularly Western Antarctica.
Five times more marine fish may be at risk of extinction: study
What’s new: The number of bony marine fish species at risk of extinction could be five times higher than previously estimated by conservation scientists, a recent study suggests. What the study says: Bony fish, or teleosts, represent some 96% of the world’s marine fish species. The IUCN Red List of Threatened Species, the global reference […]
As logging intensifies forest fires, Wet’suwet’en fight to protect old growth
- Members of Wet’suwet’en Nation in British Columbia want to conserve a pristine old-growth watershed, Caas Tl’aat Twah, in its traditional territory. The nation has obtained a logging deferral for Caas Tl’aat Twah and is planning how to protect it permanently.
- Scientists have shown that industrial logging can increase fire intensity in forests by drying out the land. Conserving remaining intact forests such as Caas Tl’aat Twah can prevent fires from getting even worse, they say.
- After decades of large-scale industrial logging only 20% of old growth forests remain in British Columbia. In 2020, the province reported that one-quarter of remaining forests were at high risk for logging and pledged to pause cutting while making land use decisions.
- But four years on, less than half has been deferred — and the province could ultimately authorize logging it.
Scientists find unexpected biodiversity in an African river, thanks to eDNA
- Scientists have used environmental DNA analysis to identify 125 species of aquatic and terrestrial animals in the remote Corubal River in West Africa.
- The identified species include critically endangered animals as well as species that weren’t previously known to occur in the region.
- The Corubal flows through Guinea and Guinea-Bissau; because of its remote nature, there haven’t been a lot of large-scale attempts to study the biodiversity in the river and its basin.
- The scientists are also working to collect specimens and tissue samples from animals encountered along the river to build a DNA reference database for the future.
Will we be ready? Geoengineering policy lags far behind pace of climate change
- The history of geoengineering policymaking has been piecemeal over past decades, with U.N. bodies failing to create or implement rigorous binding international regulatory frameworks for geoengineering management, and with academia and think tanks delivering reports and recommendations that offer little definitive detailed regulatory guidance.
- Now, as climate change impacts intensify, the debate over what safe, effective national and international geoengineering policies should look like has intensified among academics, regulatory and advisory bodies and researchers.
- Meanwhile, scientists continue trying to find out if geoengineering (the deliberate altering of global atmospheric or oceanic conditions), can help cool off a dangerously warming planet without triggering harmful effects.
- Some warn geoengineering is too risky and want field research stopped. Others say research is urgently needed so decision-makers can understand geoengineering options and risks, so as to make informed choices. For now, few definitive road signs exist to guide policymaking.
Arctic melt ponds influence sea ice extent each summer — but how much?
- July marks the midpoint of the summer sea ice melt season, during which ice declines rapidly under the almost constant Arctic sun, and melt ponds form on ice floes. Scientists study melt ponds to better understand sea ice dynamics and to help forecast the annual sea ice minimum in September.
- Sea ice melt ponds absorb more solar energy than bare ice or snow but far less than open ocean, which complicates the story of summer sea ice melt. But in the past, scientists lacked the tools to accurately measure melt pond impacts.
- New remote sensing data look at sea ice from different satellite resolutions. High-resolution imaging sends a clear picture of melt ponds in a very small area, while low-resolution imaging produces a fuzzy picture of them across the entire Arctic.
- A combination of satellite data and on-the-ice observations now help scientists track the evolution of sea ice melt ponds and their influence on the overall decline of sea ice in the Arctic.
Cloud brightening over oceans may stave off climate change, but with risk
- Marine cloud brightening (MCB), the spraying of sea salt aerosols or other fine particles into clouds to artificially brighten them and increase the sun’s reflectivity, is a proposed strategy to ward off the full effects of climate change.
- However, this solar radiation management (SRM) geoengineering technique is highly controversial, and experts say governance of MCB field experiments and deployment is needed now at the national and international levels.
- Ongoing efforts to include marine cloud brightening under an international anti-marine pollution treaty, the London Protocol, could be one effective route to setting standards for research and field experiments.
- But if MCB is deployed on a large scale, some experts say there is the potential for serious negative effects on the global climate system. These impacts could be especially severe if deployment is uncontrolled and lacks science-based governance.
Streetlights make tree leaves tougher for insects to eat, Beijing study shows
Plants that grow under the glare of artificial lighting like streetlights have tougher leaves that insects find hard to eat, new research has found. This finding suggests that artificial light at night could be a potential threat to urban biodiversity, study co-author Shuang Zhang, an ecologist at the Chinese Academy of Sciences, told Mongabay in […]

Study looks at how various tree species dominated different parts of the Amazon
Some tree lineages in the Amazon have deep evolutionary roots, dating back to the time of the dinosaurs, while others evolved much more recently. A newly published study has found that such tree diversity is strongly associated with local environmental conditions, like soil type. Scientists have long sought to better understand the origins of the […]
Geoengineering gains momentum, but governance is lacking, critics say
- As the climate crisis advances, geoengineering — intentionally modifying Earth systems on a large scale to cool the planet or store additional carbon — is increasingly a hot topic. But an intense debate is raging as to how to govern research and deployment of these deeply contentious strategies.
- Stratospheric aerosol injection (SAI) — involving the release of sunlight-blocking particles such as sulfur dioxide into the lower atmosphere to block the sun’s rays — is at the forefront of a range of geoengineering technologies and approaches.
- Most SAI research to date involves modeling, while small-scale experimentation is foundering. SAI, though likely capable of cooling Earth’s climate, comes laden with governance challenges, myriad uncertainties and knock-on effects to the climate, ecosystems and human health.
- Projected deployment within a decade or two is cause for concern, say experts who warn that policy guidance and regulatory mechanisms at the national and international levels are now patchy at best, leaving huge gaps in oversight, transparency and monitoring of field research and potential deployment.
First-ever video of Amazon weasel recorded in Bolivia
Coffee growers in Bolivia recently chanced upon an incredibly elusive animal on their farm: the rarely seen Amazon weasel. This is the first time this species has been reported in Bolivia, researchers write in a new study. “What a brilliant discovery,” Kristofer M. Helgen, chief scientist and director of the Australian Museum Research Institute, who […]
Don’t even study it: Geoengineering research hits societal roadblocks
- As climate change accelerates, some scientists are calling for more field research into solar geoengineering concepts. However, these ideas are running into opposition from other researchers, some governments and the public.
- A series of recent setbacks has put solar geoengineering research on the back foot, attempting to figure out a way to navigate the opposition.
- Proponents of field research say it would help humanity better understand the potential and problems with solar geoengineering, while opponents argue that there are too many risks and it could take our eye off the ball: cutting carbon emissions.
- The debate has spilled into the international arena, pitting nations that support greater research against those that would like to see a solar geoengineering non-use agreement.
Oxygen made by metal redefines scientific understanding
Potato-sized lumps of metal on the seafloor are generating oxygen, a new study has found. Scientists previously believed that oxygen was strictly formed as a byproduct of photosynthesizing plants. However, these oxygen-producing bits of metal, called polymetallic nodules, were found in the deep ocean, far beyond the reach of the sun’s rays. Researchers made the […]
Sun block: The promise and peril of solar geoengineering
- Recent research and interest, especially from the U.S. government, has pushed a solar geoengineering idea known as SAI, or stratospheric aerosol injection, to the top of lists of potential ideas to cool the planet. SAI would use fleets of high-flying aircraft to disperse sunlight-reflecting particles, including sulfates, into the stratosphere.
- As climate change worsens and carbon emissions continue to rise, researchers say we must be ready with other potential tools to stave off total catastrophe, such as the disintegration of the West Antarctic Ice Sheet with sea-level rise that would drown coastal cities.
- But critics say any geoengineering is too unpredictable and could allow governments to lower their ambitions on cutting emissions. They also argue that there’s no global governance policy to implement geoengineering justly.
- As debate intensifies, however, some feel it’s only a matter of time, given the current and projected trajectory of warming, until the world seriously considers geoengineering deployment.
‘Masters of deception’ cuckoos evolving into new species
Many cuckoos like to outsource their parenting. These medium-sized birds lay their eggs in the nests of other bird species, tricking the unsuspecting hosts into raising their chicks. In some cuckoo species, the chicks grow alongside the host’s offspring. In others, the cuckoo chicks eject the hosts’ babies from the nests. This deception can be […]
Scientists in Thailand collect roadkill to learn about microplastics
Researchers in Thailand have used an unexpected source to study plastic pollution in terrestrial wildlife—roadkill. Most studies investigating the impacts of plastic on wildlife have focused on oceans; upwards of 12 million metric tons of plastic enter the oceans from land each year. However, a recent study published in PeerJ shifts attention to how microplastics […]
The nine processes that keep Earth stable
Modern humans, (Homo sapiens), evolved some 300,000 years ago. But modern human societies as we know them—think agriculture, animal domestication, and industrialization—developed only in the last 10,000 years or so. This was largely thanks to a stable climate that emerged around 12,000 years ago. The stability of the planet that allowed human civilization to flourish […]
In a desertscape in Brazil, science brings farms to bountiful life
- Located in the south of Brazil’s Piauí state, the municipality of Gilbués is one of four zones in the country currently experiencing desertification.
- The affected area covers 805 km2 (311 mi2) of degraded Caatinga dry forest that’s home to some 149,000 people.
- In 2006, a pioneering federal program experimented with various ways to control soil degradation and recuperate degraded areas of desertified land in Gilbués, making farming possible, even profitable, here.
- The program ended in 2016 for uncertain reasons, but the legacy of transforming the earth continues among the farmers in Gilbués, which today is one of Piauí’s top corn-producing municipalities.
Studying snakes without rattling them? There’s now tech for that
- Scientists have used tiny, noninvasive radio transmitters and accelerometers to study the habitats and behaviors of red diamond rattlesnakes.
- While the radio transmitters help researchers keep track of the snakes, the accelerometers give them an in-depth understanding of the snakes’ physical movements as they hunt, eat and even mate.
- Historically, tracking snakes has involved surgically implanting telemetry radios into them, but this process is time-consuming and also risks infecting the animals.
- Red diamond rattlesnakes, native to southwest California in the U.S. and Baja California in Mexico, face increasing threats from habitat loss and vehicle strikes.
34,000-year-old termite mounds in South Africa are still being used
- Termite mounds in Namaqualand, South Africa, are at least 34,000 years old, according to a recent study.
- The termite mounds are still used by southern harvester termites (Microhodotermes viator), making them the oldest known inhabited termite mounds by a lot.
- The discovery also unearthed organic material buried deep inside the mound, demonstrating that the termites help to store carbon at depths greater than 1 meter (3 feet).
- Scientists are planning further research to understand how much carbon is stored in these termite mounds and how fast it is accumulating.
If forests truly drive wind and water cycles, what does it mean for the climate?
- Theoretical physicists Anastassia Makarieva and Viktor Gorshkov developed the controversial “biotic pump” theory more than a decade ago, which challenges traditional climate and hydrological science.
- The theory posits that forests drive moisture-laden air currents, thereby governing wind and rain and implying that further global forest loss could have unknown effects on weather and water supplies.
- While yet to be disproven or validated, some scientists say it’s vitally important to study and test this theory, and potentially include it in climate-modeling scenarios.
- Makarieva joins Mongabay’s podcast to discuss the theory and its implications for future climate modeling with co-host Rachel Donald.
Crowdsourcing eDNA for biodiversity monitoring: Interview with Kristy Deiner
- Scientists at ETH Zurich launched a global project to gather biodiversity data from 500 lakes around the world.
- As part of LeDNA, citizen scientists from around the world collected environmental DNA samples from lakes to commemorate the U.N.’s International Day for Biological Diversity.
- With the samples, the team behind the project aims to understand more about how lakes could potentially serve as “sensors” detecting the richness of life in the catchments surrounding them.
Nepal’s legal barriers hinder genetic research, forcing scientists to improvise
- Nepali researchers face significant challenges in conducting genetic studies due to lack of legislation to allow the export of biological samples, which hinders the quality and efficiency of their research.
- Researchers are forced to use under-equipped local labs or alternative methods such as museum samples, resulting in delayed and often unsatisfactory results that impact the validity of their studies.
- The government’s restrictions, partly motivated by fears of biopiracy and a lack of regulatory commitment, result in missed opportunities for advancing conservation science and better protecting Nepal’s biodiversity, researchers say.
Know your salamander: To conserve amphibians, study their intelligence (commentary)
- In the global amphibian crisis, salamander numbers across the species have dropped too, with around 60% of salamander species threatened with extinction. Researchers and conservationists need to start looking into amphibian intelligence to find new, effective ways to conserve them.
- Salamanders possess number system and memory post hibernation, and they show evidence of self-recognition, spatial reward learning and associating color with reward. Despite having a relatively simple brain structure, salamanders are capable of complex cognition, which can be used to save them from extinction.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.
Yucatán Peninsula’s hidden underground life tracks changes at the surface
- Scientists from Northwestern University in the U.S. led a series of underwater expeditions collecting water samples from the deep web of caves and sinkholes in the Yucatán Peninsula.
- The southeastern region of Mexico is crisscrossed by numerous flooded and interconnected tunnels, functioning as subterranean rivers — crucial arteries that maintain ecosystems and support millions of people, and connecting directly to the sea.
- Any disruptions to the microbial communities in these waters could have significant consequences for both humans and marine ecosystems.
- This research is crucial for assessing the potential environmental impacts of large-scale agriculture or major projects like the building of the Tren Maya railway line.
Polar warning: Warming temperatures mean more than melted ice
- The Arctic and Antarctic are changing rapidly in response to global warming, with scientists striving to understand how escalating impacts on these unique regions impact the rest of the world. This story summarizes three significant recent studies.
- A new comprehensive greenhouse gas budget for Arctic terrestrial ecosystems estimates that the permafrost-covered region now emits more greenhouse gases — including carbon dioxide (CO₂), methane (CH₄) and nitrous oxide (N₂O) — than it stores. That trend is expected to accelerate if Arctic warming worsens further.
- Another recent study looked at the ice shelves edging the Antarctic continent, which act as brakes slowing the flow of glacial ice into the ocean that adds to sea-level rise. Although many factors impact the mass and stability of these shelves, a new model shows El Niño warming events help melt ice from below to increase shelf loss.
- Scientists also analyzed a record-breaking heat wave hitting Antarctica in March 2022, when temperatures soared by up to 40°C (72°F) above normal. They determined that this “black swan” event is having long-term impacts on the region’s ecosystems. The odds are that more such high-heat events will occur in future.
Report ranks 60+ ideas, including geoengineering, to save the Arctic
- Given that the serious impacts of climate change are rapidly escalating, some scientists, backed up increasingly by governments, are looking into extreme measures such as geoengineering to slow the rate of change.
- A new report examines 61 climate mitigation ideas for the Arctic, including geoengineering.
- The report ranked tried and true measures, like restoring peatlands, the highest, but some geoengineering ideas, such as solar geoengineering, also ranked high.
- Researchers say, however, that while geoengineering ideas may be worth studying, the goal right now must be to aggressively cut emissions. Some also fear that geoengineering will become a costly distraction, diverting attention from the need for fossil fuel companies to cut production, and for decarbonization of the economy.
Indonesia civil society groups raise concerns over proposed Borneo nuclear reactor
- Indonesia’s largest environmental advocacy group, Walhi, staged demonstrations in Jakarta and West Kalimantan province to raise awareness about a proposed nuclear power plant in West Kalimantan’s Bengkayang district.
- In 2021, a U.S. agency signed a partnership agreement with Indonesia’s state-owned power utility to explore possibilities for a reactor in the province. Survey work is currently being conducted to determine the project’s viability and safety.
- Some environmental groups have questioned the merit of the plan on safety grounds and the availability of alternative renewable sources.
Experts highlight importance of ‘prebunking’ to combat climate disinformation
- For journalists covering climate change and other complex issues, battling disinformation is a major challenge.
- Disinformation experts use a method called “prebunking” to reveal deceptive techniques and guard against manipulation; it’s a proactive approach, rooted in inoculation theory in psychology, which encourages critical thinking in the face of false information.
- However, the method faces cultural obstacles in some countries such as Bhutan; communication professionals say journalists and local communities should receive training so they are informed about climate science and other relevant subjects in order to fight disinformation.
Scientists explore nature’s promise in combating plastic waste
- Since 1950, humanity has produced more than 8.3 billion metric tons of plastic. Most has ended up in landfills or the environment. Now, scientists are working on biological solutions to address the plastic pollution crisis at every stage of the material’s life cycle.
- Innovative new filters built from naturally occurring ingredients can capture micro- and nanoplastics in all their diverse forms. These filters could remove plastic contamination from drinking water, and prevent microplastic pollution in industrial and domestic wastewater from reaching rivers and oceans.
- Plastic-degrading enzymes, isolated from microbes and insects and engineered for efficiency and performance in industrial conditions, can break plastics down at the molecular level and even be used to turn plastic waste into new useful chemicals.
- Biological solutions are being developed for a range of pollutants, not just plastics. But this technological research is still young. Crucially, we must not allow solutions for existing pollutants to make us complacent about the impact of new chemicals on the environment, or we could risk making the same mistakes again.
Study challenges use of charismatic wildlife as umbrella species for conservation
- A new study from Indonesia’s Leuser forests challenges the traditional use of charismatic “umbrella species” like tigers and rhinos to represent ecosystem biodiversity.
- Researchers found that focusing on these well-known species neglects other important wildlife and may not accurately represent overall biodiversity.
- Instead, the study proposes a data-driven approach using camera-trap data to identify the most suitable umbrella species based on their association with higher levels of community occupancy and diversity.
- The study identified the sambar deer and Sunda clouded leopard as better umbrella species than tigers and rhinos in the Leuser Ecosystem, highlighting the need for a more comprehensive approach to wildlife conservation that includes multiple species, not just the most charismatic ones.
DNA analysis of rare Philippine fruit dove sheds new light on a 70-year mystery
- The Negros fruit dove is known to science from a single female sample collected in the Philippines in 1953; nothing is known about its habits, song, or even what the male of the species looks like.
- A recent genetic analysis supports the identification of the dove as a unique species within the genus Ptilinopus.
- It also identifies habitats where the bird may possibly still be found, based on statistical analysis of its historical range.
- Whether any Negros fruit doves survive remains a mystery, but researchers say ongoing surveys paired with modern technology like audio loggers and environmental DNA monitoring might help find the species in the wild.
Postponement of century-old Indian Science Congress sparks controversy
- Almost every year since 1914, the Indian Science Congress has brought together a wide range of scientists, academics, students and even Nobel laureates in an event that has been central to the development of science throughout India.
- This year, the Indian Science Congress was postponed amid reports of controversy between the organizing body and the Indian government.
- Meanwhile, the Indian Science Congress Association has been accused of politicizing the event in recent years and providing a platform for pseudoscience, sparking protests among many in the scientific community.
New AI model helps detect and identify microplastics in wastewater
- A new model developed by researchers at the University of Waterloo in Canada uses advanced spectroscopy and artificial intelligence to identify the presence of microplastics in wastewater.
- Researchers trained PlasticNet to detect microplastics based on how they absorb and transmit different wavelengths of light that they’re exposed to.
- The tool successfully classified 11 types of common plastics with an accuracy of more than 95%; it could potentially be used by wastewater treatment plants and food producers to identify microplastics.
- The team is currently working to make the model work faster and more efficiently, and to also streamline the process of gathering data.
‘No end in sight’ for potential of conservation tech: Q&A with Megan Owen
- For the past seven years, the conservation technology lab at the San Diego Zoo Wildlife Alliance has been working to develop and deploy technology that can automate the collection and processing of wildlife data.
- Running a tech lab in a zoo has the benefit of providing scientists with a setting where they can use the wildlife in their care to validate the data and calibrate the technology.
- Team members at the lab are also working to develop and mentor the next generation of conservation technologists who can keep up with the rapidly evolving field.
- Making the technology “low-cost and accessible, fixable, deployable and programmable” continue to be some of the challenges that the team is working to overcome, according to SDZWA vice president of conservation science Megan Owen.
2023’s top 10 Indigenous news stories (commentary)
- Indigenous experts from leading Indigenous organizations and the U.N. share their list of the top 10 Indigenous news stories from 2023.
- This year saw many emerging trends, including the creation of funding mechanisms led by Indigenous organizations, criticism of carbon markets, record-breaking heat, and Indigenous women’s growing role as leaders.
- While the presence and recognition of the role of Indigenous people in conservation continues to expand, experts say the recognition of their rights and inclusion continues to be a challenge.
- This post is a commentary. The views expressed are those of the authors, not necessarily Mongabay.
How a 160-year-old pelt piqued new findings on Indigenous ‘woolly dog’ breed
- Researchers from the Smithsonian National Museum of Natural History recently studied and analyzed a 160-year-old pelt of an extinct woolly dog, part of a breed that Indigenous Coast Salish communities cared for for thousands of years.
- For the first time, the study sequenced the woolly dog’s genomes to analyze the species’ ancestry and genetics and the factors contributing to its sudden disappearance at the end of the 19th century.
- Based on the genetic data, they estimated that woolly dogs biologically evolved from other breeds about 5,000 years ago.
- Researchers say numerous socio-cultural factors are likely responsible for the species’ disappearance. Chief among them were the impacts of European colonization.
Study on evolution of same-sex animal behaviors underscores stigmas in research
- A new study tracing the evolution of same-sex sexual behavior in mammals, using phylogenetic analyses, suggests these behaviors may have evolved in part to strengthen social bonding and relationships.
- Same-sex sexual behavior was observed in 261 species, which constitutes 4% of all mammal species; the research adds to a growing list of some 1,500 animal species in which same-sex sexual behavior is documented.
- Interest in this research is expanding after a long history of stigma within the field that led some earlier scientists to withhold evidence of same-sex sexual behavior among animals; at the time, such behavior was considered an error in the research findings — or “perverted.”
- Researchers also note that stigmas have long prevented scientists from investigating same-sex sexual behaviors in animals or receiving funding to carry out such studies.
Community tropical forest management linked to social & environmental benefits: Study
- A study shows that forests in 15 tropical countries across Africa, Asia and Latin America managed by Indigenous peoples and local communities are associated with improved outcomes for carbon storage, biodiversity and forest livelihoods.
- The study finds that the positive outcomes were most likely observed when formal management institutions were in place and Indigenous and local communities had influence in defining their rights and roles in forest use and management.
- The findings suggest that governance reforms, like supporting Indigenous and local community rights or roles to manage forests, can play a role in supporting both human and environmental goals in tropical forested landscapes.
- However, giving local people formal rights is just a starting point, the lead author says; other procedures and support need to be in place to determine whether people actually get those rights and if they are able to use them to good effect.
Track-a-mole: Sniffer dog and eDNA help ‘rediscover’ South African golden mole
- A sniffer dog and environmental DNA analysis enabled researchers to confirm the continued existence of the rare De Winton’s golden mole, not seen by scientists since 1936.
- The habitat near Port Nolloth, South Africa, where the critically endangered mole was found, is currently unprotected and threatened by development and mining.
- De Winton’s moles are one of the of 25 “most wanted” lost species that have been found again by science.
Collaboration key to rediscovery of egg-laying mammal in Papua’s Cyclops Mountains
- Collaboration between international and local researchers, conservation authorities, NGOs and Indigenous groups was key to the success of an expedition in Indonesia’s Cyclops Mountains that uncovered new sightings of a rare egg-laying mammal and multiple unidentified species.
- “I think the trust between the expedition team and the community was important in the success of the expedition, and a lack of trust may have contributed to former searches being less successful,” said University of Oxford researcher James Kempton who proposed the expedition in 2019.
- The highlight of the expedition was camera-trap images of Attenborough’s long-beaked echidna, distantly related to the platypus, which scientists hadn’t seen since 1961 and which they’d long feared was extinct.
- The expedition also found the Mayr’s honeyeater, a bird scientists haven’t seen since 2008; an entirely new genus of tree-dwelling shrimp; countless new species of insects; and a previously unknown cave system.
To keep track of salmon migrations in real time, First Nations turn to AI
- Partnering with First Nations, a new interdisciplinary study proposes harnessing artificial intelligence and computer-based detection to count and produce real-time data about salmon numbers.
- Monitoring their population when they return to the rivers and creeks is crucial to keep tabs on the health of the population and sustainably manage the stock, but the current manual process is laborious, time-consuming and often error-prone.
- Fisheries experts say the use of real-time population data can help them make timely informed decisions about salmon management, prevent overfishing of stocks, and give a chance for the dwindling salmon to bounce back to healthy levels.
- First Nations say the automated monitoring tool also helps them assert their land rights and steward fisheries resources in their territories.
The Indo-West Pacific harbors two distinct mangrove hotspots, study says
- New research on slugs has found two types of mangrove forests in the Indo-West Pacific region, highlighting their much-needed protection against deforestation and rising sea levels.
- The Indo-West Pacific is known to have the highest diversity of mangrove plants in the world, but it wasn’t previously clear which parts of the region had peak diversity.
- The latest research found the mangrove forests of the archipelagic region that spans from Papua New Guinea to Malaysia differ in numerous characteristics, including sediment size, freshwater input and plant species.
Indonesia reports a new Javan rhino calf, but population doubts persist
- Indonesian officials have reported the sighting of a new Javan rhino calf in Ujung Kulon National Park, home to the last surviving population of the critically endangered species.
- While the discovery of the female calf is good news, it comes amid growing doubt about official claims that the species’ population is increasing steadily.
- The Indonesian government puts the Javan rhino’s current population at about 80 animals, with an average of three new calves added per year.
- Its past estimates, however, have counted rhinos that have disappeared (some of which were confirmed dead), throwing into question whether the species’ population trend is really increasing or even declining.
Applications open for Airbus’s ‘Satellites for Biodiversity Award’
- The second edition of the “Satellites for Biodiversity Award” has been announced by the Airbus Foundation and the Connected Conservation Foundation.
- The two organizations are accepting applications until Dec. 15 for an award to support the use of high-resolution satellites for monitoring, tracking and protecting global biodiversity.
- Winners will receive access to Airbus’s high-resolution Pléiades and Pléiades Neo satellites, along with access to global mapping software from Esri and funding of $6,000.
- Previous winners include a project to map elephant habitats in Sai Yok National Park in Thailand, and community-led efforts to use drones and satellites to save tree kangaroos in Papua New Guinea.
Sensing tech used in oil pipelines can also track Arctic sea ice, study shows
- Scientists have used undersea fiber-optic cables in the Arctic to remotely track the presence and extent of sea ice.
- Sea ice is usually monitored with the help of satellites; however, the lack of high-resolution images and the low frequency of data collection makes it difficult to do in-depth analysis.
- Using a method commonly employed to monitor oil pipelines and highways, the scientists looked for changes in signals sent down a fiber-optic cable in the Beaufort Sea that would indicate the presence of sea ice.
- While promising, the method can’t yet be used to measure the thickness of sea ice or to determine how far the ice extends to either side of the cable.
Indonesian voters want a clean energy plan, but candidates haven’t delivered
- Candidates running in Indonesia’s presidential election next year must make clear their plans for transition the country away from fossil fuels and toward clean energy, policy experts say.
- A survey shows young Indonesians, who make up the majority of potential voters, view environmental issues in general, and a just energy transition in particular, as crucial issues for a new president to tackle.
- However, none of the three hopefuls who have declared their candidacies to date have addressed these issues, with the survey reflecting a sense of pessimism among respondents.
- Indonesia, a top greenhouse gas emitter, has said it aims to hit net-zero emissions by 2060 and retire its existing fleet of coal-fired power plants, but continues to build more coal plants to serve its growing metal-processing sector.
In the chain of species extinctions, AI can predict the next link to break
- Scientists at Flinders University in Australia have developed a machine-learning model that predicts which species are at risk of extinction if another species is removed from an ecosystem or an invasive one is introduced.
- Trained on data on how species interact with each other, the model could serve to alert conservation managers on which vulnerable species to focus on, the developers say.
- They tested the model successfully in Australia’s Simpson Desert, where it accurately predicted which species invasive foxes and cats preyed on.
- However, the shortage of data on species interactions, along with the possible biases that arise, are gaps that still need to be filled in the model.
To protect the oceans, we must map them (commentary)
- About 80% of our oceans remain “unmapped, unobserved, and unexplored,” according to NOAA.
- Technologies like un-crewed marine drones, high-resolution satellites, and remote operating vehicles are now being paired with modern digital mapping techniques to reveal critical new insights about the oceans.
- “Considering we’ve barely mapped a quarter of [the oceans] so far, imagine what we could know, what we could prepare for, if every inch was mapped,” a new op-ed suggests.
- This article is a commentary. The views expressed are those of the author, not necessarily Mongabay.
Machine learning helps researchers identify underground fungal networks
- Researchers are using remote-sensing technology and machine-learning algorithms to map and predict the presence of mycorrhizal fungi in ecosystems around the world.
- The Society for the Protection of Underground Networks (SPUN) is an initiative that aims to map the distribution of fungal networks to spread awareness and advocate for their protection.
- Mycorrhizal fungi form symbiotic relationships with plants, serving as a vital interface for transferring water and nutrients from the soil while also storing massive amounts of carbon underground.
- SPUN is also working to provide financial and technical support to researchers and local communities to help them map fungal networks in their home countries.
Nuclear pioneers press ahead with plans for Indonesia island frontier
- PT ThorCon Power Indonesia is moving closer toward building an experimental nuclear reactor on a remote island in a strait bisecting the islands of Sumatra and Borneo.
- The company says the electricity generated by a thorium-powered reactor could generate electricity at 3 cents per kilowatt hour while emitting close to zero greenhouse gases.
- Some worry the project could threaten delicate marine ecosystems on an island that was, until recently, protected as a conservation area.
Calls grow to put the brakes on deep-sea mining as countries discuss rules
- Deep-sea mining is facing growing opposition from various countries, including Canada, Sweden, Ireland and Switzerland, as well as the U.N. human rights chief and a major seafood industry group.
- On July 10, the International Seabed Authority (ISA), the U.N.-associated deep-sea mining regulator, began a set of highly anticipated meetings in Kingston, Jamaica, to discuss adopting mining regulations.
- Commercial deep-sea mining has not yet begun. One firm previously said it intended to apply for a mining license later this year, adding urgency to the discussions.
- Mining companies say it’s necessary to mine the deep sea to extract minerals for renewable technologies; scientists and other experts say seabed minerals aren’t required for these technologies, and this mining could cause irreparable damage to the marine environment.
What does the decline of natural history museums mean for biodiversity conservation? (commentary)
- Many important natural history museums are struggling to survive due to reduced funding and staffing, and so their collections are increasingly being split up, degraded, or hived off.
- A review of these trends, addressing the problems with such museums and suggesting solutions, was recently published in the journal Megataxa.
- “Institutional declines need not be seen as inevitable, but should at least be acknowledged before things may be improved. We have all-too-silently borne witness to declines or extirpations of natural history museums, not just in London, Paris or in the tropics,” a new op-ed argues.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.
Strengthening crops with insect exoskeletons? Study says yes, by way of the soil
- Supplementing soil with insects’ cast-off outer skin after a molt can help increase plant biomass, the number of flowers, pollinator attraction, seed production, and even resilience to insect herbivore attacks, according to researchers.
- Farmers are already using insects, in particular the black soldier fly, for livestock feed and waste reduction, and this new use could help the transition to a more sustainable and circular agricultural system, scientists say.
- Along with further investments in research and development, a higher uptake in insect farming practices, by both small and industrial farmers, will improve for boosting crop productivity within circular agriculture.
Even in recycling, microplastics remain a persistent polluter, study shows
- New research has found that a “state-of-the-art” plastic recycling facility in the U.K. could be releasing up to 75 billion microplastics per cubic meter of wastewater annually.
- This amount of plastic waste accounts for about 6% of the plastic that enters the facility to be recycled, according to the study authors.
- The researchers found that 80% of these plastic particles were smaller than 10 microns — a size of plastic known to be detrimental to human health when inhaled or ingested.
How will climate change affect Latin America? Scientists respond to IPCC report
- Mongabay Latam spoke with scientists who contributed to the latest Intergovernmental Panel on Climate Change (IPCC) report about the effects in Latin America, opportunities for mitigation and adaptation and the contributions of Native cultures.
- IPCC released the latest report in March as a synthesis summarizing the six previous reports it has issued on the situation of the planet since 2015.
- The new scientific report warns once again of increased global warming, but also mentions that solutions exist with the help of technology and local communities.
Global Ocean Census aims to find 100,000 marine species in 10 years
- A new initiative called the Ocean Census aims to expand marine biodiversity knowledge by finding 100,000 new marine species within a decade.
- It will send scientists on dozens of expeditions at marine biodiversity hotspots and use advanced technology like high-resolution imagery, DNA sequencing and machine learning, to identify new species.
- Scientists estimate that only about 10% of marine species have been formally described, and about 2 million species have yet to be identified.
New ‘snug,’ a snail with a too-small shell, described from Brunei rainforest
- A group of researchers and citizen-scientists have identified a new semi-slug species, Microparmarion sallehi, from the lowland rainforests of northern Borneo Island.
- Their study suggests there may be some half a dozen other species from the same genus waiting to be described, highlighting the rich biodiversity of this region.
- For this description, the local and international scientists involved students and laypersons in the team on a combined program of biodiversity training and exploration.
- The study authors note that scientific knowledge of Southeast Asian slugs in general is lacking due to low collection samples, meaning the prospects for describing a new species is high.
Flawed count puts ‘glorified’ Javan rhinos on path to extinction, report says
- Javan rhinos, a critically endangered species found only in a single park in Indonesia, may be on a population decline that could see the species go extinct within a decade, a new report warns.
- The report highlights questionable practices in the Indonesian government’s official population count, which has shown a steady increase in rhino numbers since 2011.
- Notably, the official count includes rhinos that haven’t been spotted or recorded on camera traps in years; at least three of these animals are known to have died since 2019.
- The report, by environmental NGO Auriga Nusantara, also highlights an increase in reported poaching activity in Ujung Kulon National Park, and a general lack of official transparency that’s common to conservation programs for other iconic species such as Sumatran rhinos and orangutans.
Uterine implants and underwater ultrasounds aim to demystify shark births
- For years, studying the reproductive biology of sharks has depended on capturing the animals and dissecting them.
- Scientists recently developed the Birth Alert Tag, an egg-shaped satellite transmitter that can be implanted in the uterus of pregnant sharks to document the location and timing of births.
- In another development, scientists took ultrasound readings of whale sharks and sampled their blood to detect if they were pregnant.
- The new methods aim to help researchers determine sharks’ pregnancy status and the location of shark births; one goal is to inform the establishment of corridors to protect the animals, which are among the most vulnerable vertebrates on Earth.
Study: Women, youths can be more effective at driving sustainable farming changes
- A study in a farming community on Indonesia’s Sulawesi Island shows that women and younger farmers can be more influential than older men in persuading peers to adopt new technologies and practices.
- The findings could have significant implications for conservation organizations trying to implement sustainable agriculture programs within communities.
- The study looked at two groups — one made up of older men perceived as “opinion leaders,” and the other of mostly women and younger men — and how effective they were at convincing fellow farmers to try out a new pair of cacao pruning scissors.
- Experts say the findings don’t mean older men no longer carry any weight when it comes to influencing community members, and that they should still be consulted and engaged with when introducing development initiatives.
CO2 in, methane out? Study highlights complexity of coastal carbon sinks
- Coastal ecosystems take in huge amounts of carbon dioxide from the atmosphere, but researchers are still deciphering how much methane, a far more potent greenhouse gas, they put back into the system.
- Researchers studying seaweed and mixed vegetation habitats in the Baltic Sea found they emit methane equivalent to 28% and 35% respectively of the CO2 that they absorb.
- The findings highlight that more work is needed to understand methane emissions in different coastal areas to get a better accounting of the carbon balance sheet.
‘Hope is action.’ David Suzuki retires into a life of determined activism
- One of Canada’s best known scientists and ecologists, David Suzuki recently announced his retirement from
hosting “The Nature of Things,” the acclaimed Canadian Broadcasting Corporation television series seen in over 40 countries.
- Also a prolific author with 52 books to his name, he has now turned his attention to becoming an ‘active elder’ in the fight to save the planet.
- “The thing about elders [is] they’re beyond worrying about money or power or celebrity, so that they can speak a kind of truth,” he told Mongabay in a new interview.
When a red snapper is more than just a fish: Q&A fisheries scientist Elle Wibisono
- Fisheries scientist and artist Elle Wibisono recently published a children’s book, “A Snapper Tale,” that features red-colored snappers native to Indonesia’s waters.
- Equipped with her extensive knowledge and experience in marine conservation and sustainable fisheries, Wibisono uses her book to highlight the importance of fish identification, a key component of sustainable fisheries.
- Indonesia is home to one of the world’s richest marine ecosystems, with its fisheries sector supplying seafood demand from home and around the world.
- Mongabay’s Basten Gokkon spoke with Elle Wibisono recently about her book and the highlighted fisheries issues, and her hopes for the impacts it will have on readers young and old and on Indonesia’s marine conservation policies.
Amazon deforestation linked to reduced Tibetan snows, Antarctic ice loss: Study
- Earth’s climate is controlled by a complex network of interactions between the atmosphere, oceans, lands, ice and biosphere. Many elements in this system are now being pushed toward tipping points, beyond which changes become self-sustaining, with the whole Earth system potentially shifting to a new steady state.
- A recent study analyzed 40 years of air temperature measurements at more than 65,000 locations to investigate how changes in one region rippled through the climate system to affect temperatures in other parts of the globe. Computer models then simulated how these links may be affected by future climate change.
- Researchers identified a strong correlation between high temperatures in the Amazon Rainforest and on the Tibetan Plateau. They found a similar relationship between temperatures in the Amazon and the West Antarctic Ice Sheet.
- Deforestation in the Amazon likely influences the Tibetan Plateau via a convoluted 20,000-kilometer (12,400-mile) pathway driven by atmospheric and oceanic circulation patterns. The study suggests that a healthy, functioning Amazon is crucial not only for the regional climate in Brazil, but for the whole Earth system.
No croak: New silent frog species described from Tanzania’s ‘sky island’ forests
- Scientists have described a new-to-science species of frog from Tanzania’s Ukaguru Mountains with a unique trait: it’s silent.
- The males of this species have tiny spines on their throats, which may serve as a means of species recognition for the females.
- Researchers encountered the species during an expedition in search of another species, the elusive Churamiti maridadi tree toad, which has only been spotted twice in the wild and is feared to be extinct.
- The Ukaguru Mountains have a high degree of endemism, and describing this new species highlights the vast amount of knowledge still to be gained about this biodiversity-rich area.
‘Not a good sign’: Study shows Greenland temperatures at 1,000-year high
- New research shows that north-central Greenland experienced the highest temperatures between 2001 and 2011 over a 1,000-year period.
- Scientists came to this conclusion after reconstructing climate conditions over the last millennium by analyzing ice cores from the Greenland ice sheet.
- This study can provide a foundation for future studies on ice melt and sea level rise, the authors say.
Forest modeling misses the water for the carbon: Q&A with Antonio Nobre & Anastassia Makarieva
- An expanded understanding of forests’ role in moisture transport and heat regulation raises the stakes on the health of the Amazon Rainforest and the need to stop cutting trees.
- The biotic pump theory, conceived by scientists Anastassia Makarieva and the late Victor Gorshkov, suggests that forests’ impact on hydrology and cooling exceeds the role of carbon embodied in trees.
- In an interview with Mongabay, Makarieva and Brazilian scientist Antonio Nobre explain how the theory makes the case for a more urgent approach by Brazilian President Luiz Inácio Lula da Silva to protect the Amazon.
Botanists are disappearing at a critical time
- The expansive field of botany could be facing a dearth of skilled experts due to a growing lack of awareness of plants, interest in studying them, and fewer educational opportunities to do so.
- Humans depend upon plants for basic survival needs, such as food, oxygen, and daily household products, but fewer students are receiving enough instruction to enable them to do much beyond basic identification.
- This lack of educational opportunities to study plants – and a general lack of interest in them – is leading to less ‘plant awareness’ and could endanger society’s ability to address existential problems like biodiversity loss and even climate change.
- The University of Leeds’s Sebastian Stroud joins the Mongabay Newscast to talk about his research highlighting this increasing lack of plant literacy, the consequences of it, and what can be done to turn it around.
Understanding reptile intelligence can aid conservation and safeguard ecosystems (commentary)
- Reptile intelligence has long been considered inferior to that of birds and mammals. But recent studies in reptile cognition show reptiles have a profound understanding of their environment.
- Reptiles’ understanding of their surroundings and their evolution of learning can play a part in biodiversity conservation and ecosystem service provisioning, especially on agricultural lands.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.
Democratizing the deep sea: Q&A with Ocean Discovery League’s Katy Croff Bell
- The current expense of studying the deep seas stymies many research initiatives, so scientists have developed a low-cost imaging and sensor device to make access to the deep sea more equal.
- Developed using off-the-shelf hardware, “Maka Niu” can capture images and collect data on temperature and salinity down to a depth of 1,500 meters, or nearly a mile.
- Scientists in countries like the Maldives, Seychelles and South Africa are now deploying prototypes to provide feedback for the final product.
Airbus Foundation looks to put satellites to new biodiversity conservation uses
- The Connected Conservation Foundation and the Airbus Foundation are currently accepting proposals for an award to support the use of satellite imagery for biodiversity conservation.
- The competition winners will receive access to Airbus’s Pléiades and Pléiades Neo satellite constellations and $5,000 in financing.
- The satellites deliver images with resolutions down to 30 centimeters (12 inches) and could be used in applications such as anti-poaching, forest monitoring, and species population assessments.
Fears for academic freedom as Indonesia doubles down on scientists’ ban
- Indonesian academics continue to question the government’s justification for banning five foreign scientists who called out the official narrative that the country’s orangutan populations are increasing.
- The initial ban made nebulous accusations that the scientists had “negative intentions” that could “discredit” the government, but the environment ministry now claims they broke the law — without specifying how.
- Indonesian scientists campaigning for academic freedom say the government’s move is a form of anti-science policy and power control over the production of knowledge.
- The environment ministry has refused to engage with either the foreign scientists or the academic freedom caucus, with researchers saying this is part of a larger trend of independent science being constrained.
Millions are spent on climate research in Africa. Western institutes get most of it
- More than 75% of funds earmarked for Africa-related climate research go to institutes in the U.S. and Europe, according to a study in the journal Climate and Development.
- Of the $620 million that financed Africa-related climate research between 1990 and 2020, research institutions based in Europe and the United States received most of the funding ($480 million), while those located in Africa got less than 15% ($89.15 million).
- However, the analysis only provides an estimate for financing trends because it leaves out a host of agencies that fund climate research, like aid organizations, and crucially is restricted to English-language research.
- What is equally, if not more, worrisome, is that the prioritization of countries as sites for research doesn’t align with the severity of the climate risks or impacts a country faces.
Here come the sunbirds: New species from Indonesia’s Wakatobi Islands
- A group of researchers have identified several new species of sunbirds whose range spans from Africa to Australia and the tropical Wakatobi Islands in central Indonesia.
- They also found evidence that could divide the more widespread species of the olive-backed and black sunbirds, Cinnyris jugularis and Leptocoma aspasia.
- The researchers said their findings reiterated recommendations to protect the Wakatobi Islands as an endemic bird area, especially as so much remains unknown to the scientific community.
- The tiny archipelago is also part of the Wallacea region that many scientists consider “a living laboratory” for the study of evolution with endemic species being newly identified to science in recent years.
As Indonesia paints rosy picture for orangutans, scientists ask: Where’s the data?
- Foreign scientists who were apparently banned for questioning the Indonesian government’s claim that orangutans are widely increasing in number insist none of the available data support the claim.
- Erik Meijaard, Julie Sherman, Serge Wich, Marc Ancrenaz and Hjalmar Kühl were blocked from carrying out conservation-related research in the country after writing an op-ed that the forestry ministry deemed had “negative indications” that could “discredit” the government.
- “If the government says that populations are growing I assume they have data that none of us have access to,” Meijaard told Mongabay. The ministry didn’t respond to requests for comment.
- The banning of the five is the latest in a string of actions by the current government that local and foreign academics have slammed as “repressing science.”
Catfished: New species described from DRC after mistaken identity
- Scientists recently identified a new species of air-breathing catfish, Clarias monsembulai, in the Democratic Republic of Congo’s Salonga National Park — the first new species of catfish in the Clarias genus to be described in 42 years.
- It was named after Congolese researcher Raoul Monsembula, who collected samples of the species in 2006 and 2010 without realizing at the time that the fish was unknown to science.
- Experts say that species discoveries are very common in Salonga National Park due to the region’s rich biodiversity as well as the limited amount of research being done there.
- However, the area also faces numerous threats, including poaching and the possibility of fossil fuel extraction.
Humans are dosing Earth’s waterways with medicines. It isn’t healthy.
- Medicines, chemical formulations that alleviate much human suffering, can also be significant pollutants, with active ingredients often excreted from the human body and entering waterways. However, the intensity of this contamination and of its impacts has not been well researched.
- A study published in June analyzed samples from 1,000 sites along waterways in more than 100 nations, looking for 61 active pharmaceutical ingredients (APIs). Their results suggest that concentrations of at least one API breached safe levels for aquatic life at nearly 40% of sites tested globally.
- Some pharmaceuticals are endocrine disruptors (EDCs), which mimic hormones and interfere harmfully with the endocrine system in various organisms, while other drugs are linked to antimicrobial resistance (AMR), considered one of the biggest threats to human health and well-being today.
- Despite growing awareness among scientists, there is no systematic reporting of waterway pollution by medicines, or impacts on ecological health. Currently, many human-excreted pharmaceuticals enter directly into waterways, or pass through existing wastewater treatment facilities. Fixing the problem will be very expensive.
Agulhas Current enigma: An oceanic gap in our climate understanding
- Comprehending the workings of western boundary ocean currents, like those of the Agulhas Current off the South African coast, may hold a key to Earth’s climate system. But understanding this particular current is hampered by a major lack of in-situ data. This gap leaves us in the dark about local, regional and global climate impacts.
- The Agulhas Current, located in the Indian Ocean, is one of the most energetic ocean current systems in the world. Changes to it can impact local weather in South Africa and elsewhere in the Southern Hemisphere, and perhaps influence large-scale climatic changes in the Northern Hemisphere and globally as well.
- However, it is not clear how and what these impacts may be, or when they may occur. With climate change escalating rapidly due to unabated human carbon emissions, it is now more important than ever that we understand the impacts of Southern Hemisphere ocean currents, and integrate their actions into climate models.
- But attempts at long-term monitoring of the Agulhas Current System have not been fully successful. Accomplishments and failures to date have underscored significant local research capacity challenges, and differences in the approach to, and financing of, ocean science in the Global North as compared to the Global South.
Scientists develop AI that can listen to the pulse of a reef being restored
- Scientists have developed a machine-learning algorithm that can distinguish healthy coral reefs from less healthy ones by the soundscape in the ecosystem.
- Previous studies had established that the sounds of life in a successfully recovered reef are similar to those from a healthy reef, but parsing all the acoustic data was slow and labor-intensive.
- The new algorithm has been hailed as “an important milestone” for efficiently processing acoustic data to answer the basic question of how to determine the progress of a reef restoration program.
- Researchers say follow-up work is still needed, including to check whether the algorithm, tested in the Pacific Coral Triangle, also works in reefs in other parts of the world.
New voyage checks in on Darwin’s species, nearly 200 years after Beagle
- On Sept. 12, 2021, French documentary maker Victor Rault set sail from Plymouth, England, aboard his sailing ship, the Captain Darwin.
- His goal is to retrace the same route taken by famed naturalist Charles Darwin nearly 200 years earlier and assess how the species he described in the 19th century are faring today.
- Rault has already made stops in Brazil, in the same places that Darwin visited, and recorded a mixed picture as a result of widespread deforestation: a decline in sloth numbers, but a boom in the population of leafcutter ants.
- At the end of his four-year voyage, Rault plans to write a book and make a documentary: “My aim is to predict what the world will look like if we decide to take action as a global community now, and not wait for the extinction of all the species.”
How a rare Colombian flower cultivated with Indigenous know-how is changing lives
- The Inírida flower, known as flor de Inírida, grows in a small area along the Colombian-Venezuelan border.
- An Indigenous leader and botanist successfully worked together to domesticate this rare and little-known flower.
- Its conservation helps ensure the long-term protection of other species while offering potential bioremediation against contaminated soil.
- Inírida’s commercialization plays a vital role in the region’s green economy, bringing in revenues for Indigenous families.
Sea life may downsize with ocean warming — bringing challenging impacts
- A new model predicts that marine microbes could shrink by up to 30% in the future due to climate change, impacting bigger organisms that eat them including fish, potentially disrupting the food chain from the bottom up. Smaller fish would mean impacted fisheries. Smaller microbes could mean less carbon sequestration.
- Warmer oceans hold less oxygen, and the model predicts that sea life will get smaller in response to more limited oxygen. But scientists have long debated why this downsizing occurs, and some say that other factors not considered in the model could impact oceanic microbes in unexpected ways.
- Accurately predicting warming impacts on marine life could improve ocean resource management.
‘We’ve got to help the oceans to help us’: Q&A with deep-sea explorer Dawn Wright
- On July 12, oceanographer and geographer Dawn Wright descended 10,919 meters (35,823 feet) below the surface of the ocean to the deepest known part of the planet, Challenger Deep, alongside deep-sea explorer Victor Vescovo.
- Wright was the first Black person to make the voyage to Challenger Deep, where she and Vescovo documented several findings, including the discovery of a beer bottle on the seabed.
- The goal of the expedition was to test out a side-scan sonar designed to go down to 11,000 m (nearly 36,100 ft) that can take detailed images of the seafloor, which was successfully achieved.
- Mongabay’s Elizabeth Claire Alberts spoke to Wright before and after her expedition to learn more about the voyage’s personal significance to Wright, the challenges in venturing this far down into the ocean, and the significance of understanding more about the deep-sea.
In Congo, a carbon sink like no other risks being carved up for oil
- New research has revealed that the peatlands of the Congo Basin are 15% larger than originally thought.
- This area of swampy forest holds an estimated 29 billion metric tons of carbon, which is the amount emitted globally through the burning of fossil fuels in three years.
- Beginning July 28, the government of the Democratic Republic of Congo, where two-thirds of these peatlands lie, will auction off the rights to explore for oil in 27 blocks across the country.
- Scientists and conservationists have criticized the move, which the government says is necessary to fund its operations. Opponents say the blocks overlap with parts of the peatlands, mature rainforest, protected areas, and a UNESCO World Heritage site.
Giant kangaroo fossil points to previously unknown species in New Guinea
- Paleontologists have described a new genus of giant fossil kangaroo, named Nombe after the Nombe Rockshelter archaeological site where the fossil was originally found in Papua New Guinea.
- The finding was a chance discovery as Ph.D. candidate Isaac Kerr was reexamining a jawbone bone found in the 1970s and originally believed to belong to the extinct genus Protemnodon, the cousin of the modern day eastern gray and red kangaroos that are found in Australia.
- There has only been limited archaeological research on the island of New Guinea to date, and the fossil record is patchy.
- The team say they hope further research will offer insights into how the island’s extraordinary modern-day biodiversity, much of which is endemic, evolved.
Brazil’s new deforestation data board sparks fear of censorship of forest loss, fires
- A new council set by the Brazilian government to vet deforestation and forest fire data from the country’s space agency has been widely slammed as a political ploy to aid President Jair Bolsonaro’s reelection bid.
- The National Institute of Space Research (INPE) has provided and analyzed deforestation and forest fire data in the Amazon since 1988 and is globally renowned for its monitoring expertise, but was left out of the new council.
- The Bolsonaro government has questioned the credibility of INPE’s data since taking office in 2019, drawing outrage from scientists and researchers for claiming that data showing a spike in deforestation under Bolsonaro was false.
- Experts have raise concerns that the new council could prevent the release of annual deforestation data, scheduled at the same time as this year’s elections, that are expected to show an alarming increase in both forest loss and fires.
New DNA test aims to help bust illegal trade in precious red coral
- There’s a brisk illegal trade in precious red corals, from the family Coralliidae, but law enforcement currently has a difficult time telling commonly traded taxa apart.
- Demand for the corals for use in jewelry and decorative objects has depleted certain populations of these ecosystem engineers.
- Scientists recently developed a new DNA test that could help determine whether a coral object belongs to a taxon that’s subject to international trade regulations.
- They express hope that the new method will “contribute to better control of international trade” and inform buyers about the species they purchase.
Colorful new corals bedeck the busy waters off Hong Kong, study shows
- Scientists have found three new species of sun corals off Sung Kong and Waglan islands in the eastern waters of Hong Kong.
- The discovery of these orange, violet and green corals brings the number of known species in the Tubastraea genus from seven to 10.
- Sun coral species don’t build reefs or host symbiotic algae, but instead live in deeper waters and eat by capturing zooplankton from seawater with their tentacles.
- The discovery “reveals how little we know about marine diversity, and how many undescribed species are still awaiting our discovery,” one of the scientists said.
Data from droppings: Researchers draw up a genetic ID map for chimps
- As part of a broader project studying the cultural and genetic diversity of chimpanzees across Africa, researchers have used fecal samples from 48 sites across the continent to create a genetic identity data set of chimpanzees across the species’ range.
- The data set supports the division of chimpanzees into the four currently recognized subspecies, as well as shedding light on historic gene flow between subspecies and between chimpanzees and bonobos.
- The data set can help conservationists determine the genetic origin of chimpanzees confiscated from the illegal wildlife trade and identify poaching hotspots, researchers say.
Andean eagles have managed to adapt to fragmenting habitats — for now
- A new study looked at black-and-chestnut eagles’ (Spizaetus isidori) ability to survive in fragmented forests in the Andean regions of Colombia and Argentina.
- Researchers found that the eagles were able to fly between fragmented forests on different mountain ranges and survive better than terrestrial predators
- However, juvenile eagles had higher mortality rates than their adult counterparts, suggesting that conservation efforts should be focused on ensuring young eagles survive into adulthood.
How marine conservation benefits from combining Indigenous knowledge and Western science
- On today's episode of the Mongabay Newscast, we take a look at two stories that show the effectiveness of combining traditional Indigenous ecological knowledge and Western science for conservation and restoration initiatives.
- Our first guest today is Dr. Gary Paul Nabhan, an ethnobotanist at the University of Arizona. He tells us about eelgrass, an ancestral food of the Comcaac people in the state of Sonora in Mexico. Nabhan tells us why eelgrass is making a big comeback as a sustainable source of food for the Comcaac community and gaining international attention in the process.
- We also speak with Dr. Sara Iverson, a professor of biology at Canada’s Dalhousie University, about a research project called Apoqnmatulti’k that aims to better understand the movements of lobster, eel, and tomcod in two important ecosystems on Canada’s Atlantic coast. Iverson tells us why those study species were chosen by the Mi’kmaq people and why it’s so important that the project combines different ways of knowing, including Western science and traditional Indigenous knowledge.
Miners, drug traffickers and loggers: Is Costa Rica’s Corcovado National Park on the verge of collapse?
- Extreme polarization about what’s going on in Costa Rica’s Corcovado National Park has led to accusations of corruption, negligence, media manipulation, fights for control of the area’s management, and who does and doesn’t receive funds from international donors.
- The park suffers from artisanal gold mining, hunting, logging and drug trafficking, but officials, scientists and NGOs have very different views on how badly these things are impacting the health of the park.
- Some researchers say the populations of species like the jaguar and white-lipped peccary are on the decline, while others are optimistic about population trends and believe the park is healthy.
- Dwindling staff and budget for basic resources like food and gasoline have made it difficult to adhere to the park’s protection plan, and there’s little consensus, even on very basic things, about what the future holds for the park.
Indigenous knowledge settles question of a Bornean tree species: Study
- Awareness that much of the world’s biodiversity exists in lands and seas stewarded by Indigenous people and local communities has led scientists to reconsider the value of the knowledge systems that have achieved such successful results.
- But when it comes to species taxonomy, scientists often overlook the deep understanding of species relationships held within Indigenous knowledge systems.
- A new study from Malaysian Borneo found that two trees long recognized as distinct types by Indigenous Iban and Dusun communities, but classified as one species by Western taxonomists, are in fact genetically distinct species.
- The researchers recommend that scientists engage more often with IPLCs, especially in tropical biodiversity hotspots, and that Indigenous and local knowledge be recognized as complementary to modern science.
Even Antarctic snow can’t escape the plastic peril, study shows
- A study presents new evidence that microplastics are present in snow in Antarctica, one of the remotest places on Earth.
- Researchers collected snow samples at 19 sites across the Ross Ice Shelf in Antarctica, and found 29 microplastic particles per liter of melted snow — a higher amount than what was found in marine samples in Antarctica.
- The microplastics found in samples close to research stations were three times higher than what was found at other locations, prompting researchers to conclude that much of the plastic was coming from local clothing and equipment.
‘Strange’ giraffoid fossil shows giraffes evolved long necks to win mates: study
- The discovery of the fossil of Discokeryx xiezhi, an ancient cousin of the present-day giraffes (Giraffa camelopardalis) that roamed the earth around 17 million years ago, suggests long necks win giraffe mating wars.
- Evolutionary biologists have long debated which of the two processes —natural selection or sexual selection—plays a more important role in the evolution of the ungulate’s long necks.
- The new paper does not definitely settle the debate but adds more weight to the idea that longer necks evolved, in part, due to sexual competition and not just as a means to feed on taller trees.
Fossil evidence confirms persistence of prehistoric forests in Brunei
- A recent study published in the journal PeerJ reports the excavation of fossilized leaves from ancient forests at least 4 million years old in Brunei on the island of Borneo.
- More than 80% of the leaves the team found were from the Dipterocarpaceae family, trees that remain dominant today, confirming their long-standing role in anchoring Borneo’s species-rich ecosystems.
- The discovery adds to the urgency to protect these forests from logging or development for agriculture because once they’re gone, they will be difficult to get back, the authors say.
In Singapore, a forensics lab wields CSI-like tech against wildlife traffickers
- A wildlife forensics laboratory launched in Singapore last year is making breakthroughs in tracking down criminal syndicates trafficking in wildlife.
- Singapore is a major transit point for the illegal ivory trade; the nation impounded 8.8 metric tons of elephant ivory in July 2019 — evidence from which led to the arrest of 14 people in China.
- The researchers use the same method to capture poachers that authorities in California used to arrest the Golden State Killer.
- Elephant ivory and pangolin scales account for the bulk of the new lab’s workload; figuring out how traffickers accumulate this material from two species could uncover much of their methods.
Geoengineering Earth’s climate future: Straight talk with Wake Smith
- A new book, “Pandora’s Toolbox: The Hopes and Hazards of Climate Intervention,” explores a number of ideas for pulling carbon out of the atmosphere or artificially cooling the planet, known collectively as geoengineering.
- The book argues that such dire actions may need to be taken by future generations to combat climate change, and if so, those generations deserve to inherit research done now to understand the potential impacts and feasibility of geoengineering.
- One tool whose implementation is likely inevitable, according to the book, is pulling carbon from smokestacks and the air and then sequestering it deep in the Earth, a technology currently happening at a very small scale. Another approach, far more controversial, would be to inject aerosols into the stratosphere to cool the Earth.
- None of these methods precludes the need to decarbonize now and fast. But given the dangerous trajectory of climate change, author Wake Smith argues that suffering future generations may decide to pull the geoengineering trigger.
Where satellites come up short, drones can fill in a picture of our oceans
- Marine researchers are increasingly turning to aerial drones for a new view of the ocean, given that their resolution is much finer than that of satellites.
- While drones are used in all kinds of ways in marine studies, researchers say drones can be equipped with special sensors to track small changes in the ocean’s movements that drive much of marine life.
- Drones could be especially helpful in finding and tracking local and dangerous algae blooms, for example.
- Researchers remain hindered by regulations and cost, but that hasn’t stopped them from using drones to increase our knowledge of our blue planet.
Teaching climate issues through gameplay gains a following in Brazil
- The Climate Fresk workshop, known in Brazil as the Climate Mural, is a teaching model created in France and replicated in more than 50 countries to disseminate science-based climate knowledge in an interactive setting.
- Its main teaching tool is a card game that allows participants to understand the cause-and-effect dynamics involved in climate change.
- The workshop is usually held at universities, high schools and government facilities, but a growing number of companies have asked to host workshops to train their employees on climate issues.
- In just three years, the global Climate Fresk initiative has trained 10,000 workshop facilitators and reached more than 300,000 participants around the world.
Unseen crisis: Threatened gut microbiome also offers hope for world
- Plants and animals provide a home within themselves to an invisible community of microbes known as the microbiome. But these natural microbial communities are being degraded and altered by human-caused biodiversity loss, pollution, land-use change and climate change.
- On the macro level, habitat loss and diminished environmental microbe diversity, particularly in urban environments, is altering the gut microbiomes of humans and wild animals. Studies have linked microbiome changes to higher risk of chronic and autoimmune diseases.
- Coral bleaching is an extreme example of climate stress-induced microbiome dysfunction: During heat waves, beneficial microbes go rogue and must be expelled, leaving the coral vulnerable to starvation. Microbiome resilience is key to determining corals’ ability to acclimate to changing ocean conditions.
- There are solutions to these problems: Inoculating coral with beneficial microbes can reduce bleaching, while the restoring natural green spaces, especially in socioeconomically deprived urban areas, could encourage “microbiome rewilding” and improve human and natural community health.
Indigenous knowledge and science team up to triple a caribou herd
- A wildlife recovery effort in British Columbia, Canada, has successfully increased a caribou herd from 38 individuals to 113 in less than a decade, according to a new study.
- Two First Nations communities partnered with Canadian scientists, the government and private companies to reduce predators and care for new calves in the short term, while restoring habitat in the long term by securing more than 7,000 hectares (17,300 acres) of land for caribou.
- Human interventions, including logging and energy infrastructure, are blamed for fragmenting caribou habitat and increasing predator numbers.
- The project involves killing wolves, a main predator of the caribou, drawing ire from some conservationists.
Pilot program tries to get U.S. aquariums to raise their own fish, not catch them
- A collaboration between the New England Aquarium in Massachusetts and Roger Williams University in Rhode Island has developed protocols for breeding marine aquarium fish, including five species never before raised in captivity.
- Though some fisheries for ornamental fish are responsibly managed and benefit local economies, harmful collection practices like cyanide fishing and overcollecting can harm ecosystems.
- Aquaculture of ornamental fish can improve fish welfare, reduce the spread of disease, take the guesswork out of fish sourcing, and reduce impacts on wild populations.
Tropical trees’ growth and CO2 intake hit by more extreme dry seasons
- A new study has found that dry seasons that are warmer and drier than usual can stunt the growth of tropical trees, causing them to take in less carbon dioxide.
- While trees tend to grow more during the wet season, the researchers found that the dry season actually had a stronger impact on tree growth than the wet season.
- As climate change continues to raise temperatures, tropical trees could face increased risk of mortality and the possibility of becoming a net source of carbon, rather than a carbon sink.
Robot revolution: A new real-time accounting system for ocean carbon
- Oceans are key to understanding climate change, seeing as they take up and store 25% of the carbon that human activities add to Earth’s atmosphere. But there are big gaps in our knowledge regarding ocean carbon storage and release, and how it is evolving as climate change unfolds, a problem scientists are now addressing.
- An international deployment of thousands of robotic floats, fitted with sophisticated biogeochemical sensors, is underway and already providing real-time data that scientists can integrate into ocean carbon budgets and climate models. Many more floats are coming, with the capacity to operate in remote regions.
- One such place is the Southern Ocean around Antarctica, which accounts for almost half of the worldwide oceanic carbon sink. Windier conditions there, caused by climate change, are churning up more carbon-rich waters from the depths, releasing stored carbon and introducing unforeseen variability into ocean carbon emission estimates.
- Robots are starting to monitor these emissions in real time. More accurate ocean carbon budgets will improve accounting of land-based carbon dioxide emissions, help create more accurate assessments of how well global carbon agreements such as the Paris Agreement are meeting goals, and will help assess ocean carbon dioxide removal plans.
International funding nowhere near enough for Indonesia to cut emissions: Study
- Indonesia will have to come up with its own funding schemes to have any chance of achieving its carbon emissions reduction target by 2030, a new study says.
- The government has calculated that it needs $323 billion in funding from the international community to slash emissions by 41%, but received just $6.4 million between 2007 and 2019, the study found.
- It found that Indonesia faced difficulties accessing international climate grants, with donors often prioritizing their own interests or preferring countries with lower incomes than Indonesia.
- A potential source of funding could be the sale of government debt that’s a combination of environmental (green) bonds and Islamic-compliant bonds, known as sukuk, the study says.

‘Right moon for fishing’: Study finds gravitational impacts on plants, animals
- A recent review of the scientific literature shows that the gravitational forces that cause the tides are also associated with the rhythms of organisms such as plants, crustaceans and corals.
- Researchers say gravitational cycles are not being accounted for in scientific experiments that otherwise control for various environmental factors in the laboratory.
- In the field of gravitational effects, many practices that are repeated out of popular wisdom, such as the best time to cut wood or plant crops, still don’t have scientific backing.
‘We have a full pharmacopoeia of plants’: Q&A with Māori researcher Nicola Macdonald
- Aotearoa New Zealand’s green-lipped mussel industry provides a relatively sustainable source of animal protein, but the plastic ropes used to catch mussel larvae are a source of marine plastic pollution.
- Researchers are using mātauranga (Māori traditional knowledge) and Western science to work out whether natural fiber ropes, made from native species traditionally used by Māori, could provide a suitable and biodegradable alternative.
- Mongabay spoke with Indigenous researcher Nicola Macdonald about the research process, the findings so far, and the team’s hopes for helping create a more sustainable aquaculture industry.
Study finds major brands selling cat food that contain protected sharks
- Researchers used DNA barcoding to find that cat food sold in Singapore from at least 16 different brands contained threatened species of sharks, including silky sharks (Carcharhinus falciformis) that are protected under CITES Appendix II.
- Leading brands such as Fancy Feast, Whiskas, and Sheba were amongst those found to contain silky sharks and other species.
- None of these cat food products were accurately labeled to show that they contained sharks.
- Global shark populations are in sharp decline, mainly due to destructive fishing practices.
‘Prospect of existence’: Nameless grasshopper sparks taxonomic debate
- Researchers’ failed attempt to describe a new-to-science species of grasshopper based only on photographs has prompted a debate over established taxonomic convention.
- The grasshopper was photographed in northern Peru in 2008, and researchers from Croatia have since had their attempts to formally describe it rejected by journal after journal.
- In response to what they saw as an “arbitrary” process, the researchers wrote a paper on the challenges of describing a species from only photographs, arguing that conventions should change in an era of biodiversity loss.
- “If a living specimen is never found, it will remain a curiosity, suspended between existence and the prospect of existence,” said lead author Niko Kasalo.
Aerosol pollution: Destabilizing Earth’s climate and a threat to health
- Aerosols are fine particulates that float in the atmosphere. Many are natural, but those haven’t increased or decreased much over the centuries. But human-caused aerosols — emitted from smokestacks, car exhausts, wildfires, and even clothes dryers — have increased rapidly, largely in step with greenhouse gases responsible for climate change.
- Aerosol pollution kills 4.2 million people annually, 200,000 in the U.S. alone. So curbing them rapidly makes sense. However, there’s a problem with that: The aerosols humanity sends into the atmosphere presently help cool the climate. So they protect us from some of the warming that is being produced by continually emitted greenhouse gases.
- But scientists still don’t know how big this cooling effect is, or whether rapidly reducing aerosols would lead to a disastrous increase in warming. That uncertainty is caused by aerosol complexity. Atmospheric particulates vary in size, shape and color, in their interactions with other particles, and most importantly, in their impacts.
- Scientists say that accurately modeling the intensity of aerosol effects on climate change is vital to humanity’s future. But aerosols are very difficult to model, and so are likely the least understood of the nine planetary boundaries whose destabilization could threaten Earth’s operating systems.
In Canada, Indigenous communities and scientists collaborate on marine research
- The Apoqnmatulti’k project combines Indigenous knowledge, Western science and local knowledge holders to gather information about three important marine species in two ecosystems in Nova Scotia, Canada.
- The project comes at a time of increased urgency over management of marine species, as many fish stocks are on the decline, while access to lucrative fisheries has sparked conflict.
- Project partners say the project’s collaborative approach will provide information that could help direct stewardship and conservation of species that are important to many communities.
- As important as that new data is, project participants say the greatest insight of the project may be that forging the trusting relationships required for collaborative research takes time, which doesn’t always correspond to standard academic deadlines.
Scientists’ secret weapon to monitor the Southern Ocean? Elephant seals
- Southern elephant seals living on Kerguelen Island, a sub-Antarctic island, are helping to gather information about the Southern Ocean with data-logging devices attached to their hair.
- For instance, the elephant seals have helped gather data on sea ice formation, ocean and ice shelf interactions, and frontal system dynamics.
- The Southern Ocean provides many ecosystem services for the planet, but the region is rapidly changing due to climate change.
Preventing the next pandemic is vastly cheaper than reacting to it: Study
- A new study emphasizes the need to stop pandemics before they start, stepping beyond the quest for new vaccines and treatments for zoonotic diseases to also aggressively fund interventions that prevent them from happening in the first place.
- Researchers estimated that based on Earth’s current population and on past pandemics, we can expect 3.3 million deaths from zoonotic diseases each year in future. COVID-19 pushed numbers in 2020-21 even higher. These outbreaks are now happening more frequently, and their cost is calculated in trillions of dollars.
- Addressing the main drivers — deforestation, the wildlife trade and burgeoning agriculture, especially in the tropics — could prevent future pandemics, save lives and catastrophic societal disruptions.
Efforts to dim Sun and cool Earth must be blocked, say scientists
- Scientists are calling on political institutions to place limits on solar geoengineering research so that it cannot be deployed unilaterally by countries, companies or individuals.
- Long-term planetary-level geoengineering interventions of this kind are unprecedented and extremely dangerous, say the academics behind the letter, and should not therefore be experimented with outdoors, receive patents, public funds or international support.
- Solar geoengineering’s leading proposal — injecting billions of aerosol particles into the Earth’s stratosphere — could have severe, unintended and unforeseen consequences. Modelling suggests that it may cause drying in the Amazon rainforest
- In addition, if solar geoengineering were deployed, it would need to be maintained for decades. Sudden discontinuance would result in Earth facing what scientists call termination shock, with a sudden temperature rise due to existing atmospheric carbon emissions which would have been masked by cooling stratospheric aerosols.
Warmer, oxygen-poor waters threaten world’s ‘most heavily exploited’ fish
- A new report using core samples taken from the seabed has determined that the Humboldt Current system off the coast of Peru was home to smaller fish during the last interglacial period, 130,000 years ago.
- The conditions back then — with little oxygen content in the ocean and temperatures about 2°C (3.6°F) warmer than the average temperature in the current Holocene epoch — mirror those that scientists have predicted for 2100.
- While many studies have argued that warmer water and lower oxygen lead to smaller fish, the added pressure of industrial fishing has made it difficult to determine the threat that climate change will pose on fisheries.
- The Humboldt Current system is one of the most productive fisheries in the world, contributing to more than 15% of the global annual fish catch, so significant changes to this system will threaten food security.
Indigenous food systems can provide game-changing solutions for humankind (commentary)
- Although strides have been made in agricultural systems to feed the world population, they have also led to increased emissions and biodiversity loss.
- Indigenous food systems, practiced over millennia, can provide solutions, as shown in a recent report whose findings have spurred scientists and a coalition of several countries to work together to preserve and strengthen Indigenous food systems.
- This article is the last of an eight-part series showcasing Indigenous food systems covered in the most comprehensive FAO report on the topic to date.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.
2021’s top ocean news stories (commentary)
- Marine scientists from the University of California, Santa Barbara, share their list of the top 10 ocean news stories from 2021.
- Hopeful developments this year included big investments pledged for ocean conservation, baby steps toward the reduction of marine plastic pollution, and the description of two new whale species, Rice’s whale (Balaenoptera ricei) and Ramari’s beaked whale (Mesoplodon eueu).
- At the same time, rising ocean temperatures, a byproduct of climate change, had profound effects on marine species up and down the food chain, and action on key measures to maintain ocean resilience in the face of multiple threats hung in the balance.
- This post is a commentary. The views expressed are those of the authors, not necessarily Mongabay.
Congo Peatlands
In 2017 a team of Congolese and British scientists discover that a sprawling wetland known as the Cuvette Centrale spanning the border between the Republic of Congo and the Democratic Republic of Congo (DRC) actually contains a massive amount of peat. Their research revealed that these peatlands are the largest and most intact across the world’s […]
The past, present and future of the Congo peatlands: 10 takeaways from our series
This is the wrap-up article for our four-part series “The Congo Basin peatlands.” Read Part One, Part Two, Part Three and Part Four. In the first half of December, Mongabay published a four-part series on the peatlands of the Congo Basin. Only in 2017 did a team of Congolese and British scientists discover that a […]
Carbon and communities: The future of the Congo Basin peatlands
- Scientific mapping in 2017 revealed that the peatlands of the Cuvette Centrale in the Congo Basin are the largest and most intact in the world’s tropics.
- That initial work, first published in the journal Nature, was just the first step, scientists say, as work continues to understand how the peatlands formed, what threats they face from the climate and industrial uses like agriculture and logging, and how the communities of the region appear to be coexisting sustainably.
- Researchers say investing in studying and protecting the peatlands will benefit the global community as well as people living in the region because the Cuvette Centrale holds a vast repository of carbon.
- Congolese researchers and leaders say they are eager to safeguard the peatlands for the benefit of everyone, but they also say they need support from abroad to do so.
Holding agriculture and logging at bay in the Congo peatlands
- The peatlands of the Congo Basin are perhaps the most intact in the tropics, but threats from logging, agriculture and extractive industries could cause their rapid degradation, scientists say.
- In 2021, the government of the Democratic Republic of Congo (DRC) announced that it was planning to end a moratorium on the issuance of logging concessions that had been in place for nearly two decades.
- The move raised concerns among conservation groups, who say the moratorium should remain in place to protect the DRC’s portion of the world’s second-largest rainforest.
- Today, timber concession boundaries overlap with the peatlands, and though some companies say they won’t cut trees growing on peat, environmental advocates say that any further issuance of logging concessions in the DRC would be irresponsible.
Layers of carbon: The Congo Basin peatlands and oil
- The peatlands of the Congo Basin may be sitting on top of a pool of oil, though exploration has yet to confirm just how big it may be.
- Conservationists and scientists argue that the carbon contained in this England-size area of peat, the largest in the tropics, makes keeping them intact more valuable, not to mention the habitat and resources they provide for the region’s wildlife and people.
- Researchers calculate that the peatlands contain 30 billion metric tons of carbon, or about the amount humans produce in three years.
- As the governments of the Republic of Congo and the Democratic Republic of Congo work to develop their economies, they, along with many policymakers worldwide, argue that the global community has a responsibility to help fund the protection of the peatlands to keep that climate-warming carbon locked away.
The ‘idea’: Uncovering the peatlands of the Congo Basin
- In 2017, a team of scientists from the U.K. and the Republic of Congo announced the discovery of a massive peatland the size of England in the Congo Basin.
- Sometimes called the Cuvette Centrale, this peatland covers 145,529 square kilometers (56,189 square miles) in the northern Republic of Congo and the Democratic Republic of Congo, and holds about 20 times as much carbon as the U.S. releases from burning fossil fuels in a year.
- Today, the Congo Basin peatlands are relatively intact while supporting nearby human communities and a variety of wildlife species, but threats in the form of agriculture, oil and gas exploration and logging loom on the horizon.
- That has led scientists, conservationists and governments to look for ways to protect and better understand the peatlands for the benefit of the people and animals they support and the future of the global climate.
‘Our land, our life’: Okinawans hold out against new U.S. base in coastal zone
- Opponents of the planned relocation of a U.S. military base in Okinawa say they remain undeterred despite the defeat in elections last month of the opposition party that supported the cause.
- Local activists plan to continue opposing the relocation of the Futenma Marine base, from the densely populated city of Ginowan to the less crowded Henoko Bay coastal area.
- The proposed new facility and other military bases in Okinawa have been linked to toxic environmental pollution, military-linked sexual violence, and historical land conflicts between native Okinawans and the mainland Japan and U.S. governments.
- The Okinawa prefecture government recently rejected central government plans to sink more than 70,000 compacting pillars into Henoko’s seabed for construction, which would impact coral and seagrass that host more than 5,000 species of marine life.
Despite deals, plans and bans, the Mediterranean is awash in plastic
- The Mediterranean is considered to be one of the world’s most polluted bodies of water due to waste disposal problems in many countries bordering the sea, as well as the intensity of marine activity in the region.
- There are several existing policies and treaties in place aimed at regulating plastics and reducing plastic pollution in the Mediterranean, but experts say more international cooperation is needed to tackle the problem.
- Citizen science organization OceanEye has been collecting water samples to measure the amount of microplastics present in the surface waters of the Mediterranean.
In harm’s way: Our actions put people and wildlife at risk of disease
- While global attention is currently focused on COVID-19 and other zoonotic diseases that jump from animals to humans, diseases that breach the species barrier also pass from people and domestic animals to wild species.
- Human alteration of the planet — the felling of forests, the legal and illegal wildlife trade, climate change, and other disruptions — is driving escalating unnatural interactions between species, allowing diseases to mutate and infect new hosts.
- Infectious disease poses a serious threat to tigers, chimpanzees, Ethiopian wolves, African wild dogs and a host of other threatened species. Viral diseases spread by humans, livestock and other domestic animals could serve as the knockout punch to endangered species already teetering on the edge of extinction.
- There’s growing support for a One Health strategy, which recognizes that human health, animal health and the health of the planet are inextricably linked — that protecting the planet is crucial to the health of all.
Biosurveillance of markets and legal wildlife trade needed to curb pandemic risk: Experts
- Almost 90% of the 180 recognized RNA viruses that can harm humans are zoonotic in origin. But disease biosurveillance of the world’s wildlife markets and legal trade is largely absent, putting humanity at significant risk.
- The world needs a decentralized disease biosurveillance system, experts say, that would allow public health professionals and wildlife scientists in remote areas to test for pathogens year-round, at source, with modern mobile technologies in order to help facilitate a rapid response to emerging zoonotic disease outbreaks.
- Though conservation advocates have long argued for an end to the illegal wildlife trade (which does pose zoonotic disease risk), but the legal trade poses a much greater threat to human health, say experts.
- Governments around the world are calling for the World Health Organization to create a pandemic treaty. Wildlife groups are pushing for such an agreement to include greater at-source protections to prevent zoonotic spillover.
‘Antithetical to science’: When deep-sea research meets mining interests
- The high cost of studying deep-sea ecosystems means that many scientists have to rely on funding and access provided by companies seeking to exploit resources on the ocean floor.
- More than half of the scientists in the small, highly specialized deep-sea biology community have worked with governments and mining companies to do baseline research, according to one biologist.
- But as with the case of industries like tobacco and pharmaceuticals underwriting scientific research into their own products, the funding of deep-sea research by mining companies poses an ethical hazard.
- Critics say the nascent industry is already far from transparent, with much of the data from baseline research available only to the scientists involved, the companies, and U.N.-affiliated body that approves deep-sea mining applications.
Overfishing threatens to wipe out bowmouth guitarfish in Indonesia, study says
- A study has found that uncontrolled fishing of wedgefish, a family of rays, in Indonesia threatens to push the bowmouth guitarfish to extinction.
- The bowmouth guitarfish and the white-spotted guitarfish are the most commonly caught wedgefish species in Indonesia, with their fins supplying the shark fin trade.
- Researchers have called on the government to impose full protection of juvenile wedgefish and a reduction in catches of bowmouth guitarfish specifically to ensure their survival.
- Both the bowmouth and white-spotted guitarfish are critically endangered species, but neither is included in Indonesia’s protected species list.
New checklist aims to tackle racism in conservation science in higher ed
- A new perspective piece published in Nature Ecology and Evolution outlines the history of racism in ecology, evolution and conservation biology (EECB) while also providing an actionable checklist for departments to create an anti-racist environment.
- Written by faculty, staff and students, the checklist is a comprehensive guide to help scientists if they don’t know where to start when creating a more inclusive space.
- It outlines changes that can be made in the classroom, research labs and departments to boost the representation of non-white students in EECB, which is lower than in other scientific fields.
- More departments in ecology, evolution and conservation are thinking and talking about how to create an anti-racist space.
New research hopes to shine a light on wedgefish, the ‘pangolin of the ocean’
- Wedgefish, a type of ray, are some of the least-known and most endangered fish in the ocean.
- A new research project in Mozambique is employing two types of tags, acoustic and satellite, to better understand two of these critically endangered species.
- Researchers aim to uncover the species’ range and habitat requirements to preserve them from extinction.
- Wedgefish are heavily targeted by the shark-fin trade, and their populations have declined precipitously throughout much of their range.
Plant-based face masks? This young Philippine inventor has you covered
- A Filipino high school student has developed a plant-based wax that has shown potential in increasing the life span and effectiveness of reusable face masks.
- Kiara Raye Cartojano, 18, says she hopes the project can reduce the number of disposable face masks discarded in her city, estimated at more than 480,000 per day since the start of the COVID-19 pandemic.
- The wax is made from the leaves of the taro plant, a widespread plant with the potential to displace native vegetation and threaten agricultural crops.
Scientists look to wheatgrass to save dryland farming and capture carbon
- Intermediate wheatgrass is an imported grain that has been grown in the U.S. Great Plains and Intermountain West since the 1930s; but could it be used in marginal fields in dryland areas?
- Kernza, an intermediate wheatgrass bred by the Land Institute, is being planted in eastern Wyoming, where researchers from the University of Wyoming are uncovering whether the crop can help farmers stabilize and bolster their soils, while providing a profitable crop.
- Planting perennial crops, like Kernza, can help soil health and stability, retain moisture, and cut down on planting costs and greenhouse gas emissions from annual plantings.
Trawling bycatch increases risk of marine life extinction in Brazil
- Up to 50 kilos of fish caught in Brazil are thrown away for every kilo that arrives on land; more than 400,000 tons of marine life were discarded between 2000 and 2018 in just four states.
- Less than 10% of the 25,618 fishing boats registered by the Brazilian government are monitored by satellites, and the program that tracks fishing boats by these satellites is not publicly open and not integrated with worldwide monitoring initiatives.
- At the global level, 19 countries, regions and territories have prohibited trawling in their waters, including two in South America: Chile and Peru.
Brazil a wreck on trawling control
- The country’s lack of statistics and technical information made way for greater deregulation and private sector influence in Jair Bolsonaro’s extremist government
- The lack of control amplifies the impacts of trawling, a technique that uses fine-mesh nets to “scrape” the seabed, sweeping up everything in their path; species of low commercial value return to the waters, almost always dead.
- The sardine catch in Brazil has already fallen from 80,000 tons to about 15,000 tons annually, and stocks of mullet and other species are also shrinking; commercial species that could disappear from the map jumped from 17 to 64 (376%) between 2004 and 2014.
Swarm technology: Researchers experiment with drones to battle crop pests
- A June special edition of the Journal of Economic Entomology focuses on the potential for using drones in a number of different ways for pest management.
- Proponents of the strategy believe that drone delivery of biocontrols can be used to reduce or, in some cases, replace the use of pesticides, allowing growers to take advantage of the higher prices commanded by organic produce.
- Strict airspace regulations, limited payload capacity and high starting cost are some of the speed bumps to widespread drone usage in agriculture, but experts remain optimistic that drone-based pest management strategies will become more common in coming years.
In Indonesia, an unassuming brown bird is proof of turbo-charged evolution
- Scientists are proposing to add two new subspecies to four existing ones within the Sulawesi babbler (Pellorneum celebense) species.
- The team identified the new subspecies based on differences in DNA, body measurements and song recordings from dozens of babblers.
- Taxonomic implications aside, the study also sheds light on the phenomenon of rapid evolution, as the babblers’ genetic divergence occurred over just tens of thousands of years, rather than millions.
- But the nickel-rich soils believed to have given rise to the birds’ divergence could be hastening its demise, with mining companies eyeing their habitats for resource extraction.
New artificial intelligence tool helps forecast Amazon deforestation
- A new tool co-developed by Microsoft using artificial intelligence to predict deforestation hotspots has identified nearly 10,000 square kilometers of the Brazilian Amazon that’s in imminent danger.
- Called PrevisIA, it uses artificial intelligence to analyze satellite imagery from the European Space Agency, and an algorithm developed by the Brazilian conservation nonprofit Imazon to find the areas most prone to deforestation.
- The tool, which the developers say could potentially be applied to any forested area on Earth, will be used for preventive actions, in partnerships with local governments, corporations and nonprofits.
- The next step of the project is to build partnerships with local governments and institutions to act on preventing deforestation, which is the most challenging phase of the project, according to Imazon researcher Carlos Souza Jr.
Address risky human activities now or face new pandemics, scientists warn
- The new, highly-contagious Delta variant — spread with the ease of chickenpox — is causing COVID-19 cases to skyrocket across the globe as health officials respond with alarm. “The war has changed,” said a recent internal U.S. Centers for Disease Control and Prevention (CDC) document.
- Globally, numerous infectious diseases are being transmitted between wildlife, livestock and humans at escalating rates, including outbreaks of COVID-19, Ebola, dengue, HIV and others, as the threat of new emergent zoonotic diseases grows ever greater. The cost is huge in lives lost and ruined economies.
- The driver: human activities, particularly intrusion into wild landscapes and eating and trading wild animals. Bringing people, domestic and wild animals into unnatural proximity exposes all to pathogens for which they lack immunity. International travel and a booming global wildlife trade quickly spread viruses.
- Experts say that a “One Health” approach is urgently needed to prevent future pandemics — simultaneously addressing human, animal and ecosystem health, protecting humanity and nature, and incorporating disease risk into decision-making.
For monitoring mammals, eDNA boasts ‘killer feature’ over other methods
- Mounting evidence suggests that the fast-developing tool of eDNA could be a game-changer for terrestrial mammal monitoring.
- A new study demonstrates that eDNA analysis of stream water can reveal the diversity of terrestrial mammals in a large landscape as effectively as camera trapping and for a fraction of the cost.
- Traditional mammal survey methods can be time-consuming, expensive and far from failsafe; eDNA is a reliable and comparatively inexpensive way for conservationists to gain a snapshot of an ecosystem’s mammal fauna, scientists say.
- It could also have a big impact on conservation, since eDNA data allows timely decisions on which species to prioritize and which areas to protect.
Scientists turn to eDNA to curtail the freshwater extinction crisis
- Freshwater ecosystems are understudied and underfunded, resulting in a lack of information on what species are at risk of extinction.
- The eBioAtlas program, a partnership between the IUCN and NatureMetrics, uses environmental DNA gathered from freshwater samples to figure out what freshwater ecosystems to conserve and what species to prioritize.
- So far, a pilot study in southeast Liberia has successfully picked up environmental DNA from nearly 170 species, including some that are critically endangered.
- The new data will provide up-to-date information for the IUCN Red List of Threatened Species and empower local communities to maintain ownership of their land and water resources.
As Arctic warms, scientists wrestle with its climate ‘tipping point’
- A leaked version of the newest science report from the U.N. Intergovernmental Panel on Climate Change warns of looming, potentially catastrophic tipping points for Arctic sea ice melt, tundra thaw, savannification of the Amazon rainforest, and other planetary environmental thresholds beyond which recovery may be impossible.
- But what are tipping points, and how does one pinpoint what causes them, or when they will occur? When studying a vast region, like the Arctic, answering these questions becomes dauntingly difficult, as complex positive feedback loops (amplifying climate warming impacts) and negative feedback loops (retarding them) collide with each other.
- In the Arctic, one working definition of a climatic tipping point is when nearly all sea ice disappears in summer, causing a Blue Ocean Event. But attempts to model when a Blue Ocean Event will occur have run up against chaotic and complex feedback loop interactions.
- Among these are behaviors of ocean currents, winds, waves, clouds, snow cover, sea ice shape, permafrost melt, subarctic wildfires, aerosols and more, with many interactions still poorly understood. Some scientists say too much focus is going to tipping points, and research should be going to the “radical uncertainty” of escalating extreme local events.
Seafloor microbes hoover up methane, keeping global warming in check
- A new study found that carbonate rock mounds on the ocean floor host communities of microbes that actively consume methane, a greenhouse gas that is particularly potent if released into the atmosphere.
- The researchers found that rock-inhabiting microbes consumed methane 50 times faster than microbes that live in sediment.
- These microbes therefore play a crucial role in regulating the Earth’s temperature by consuming methane before it travels up into the water column and into the atmosphere.
Study warns of impacts of unregulated trade in Indonesian porcupines
- The unmonitored illegal trade in porcupines across Indonesia has prompted calls from conservationists for stricter protection of the species’ population in the wild.
- A new study examining seizure data of porcupines, their parts and derivatives in Indonesia has found more than 450 of the animals in nearly 40 incidents between January 2013 and June 2020
- Indonesia is home five porcupine species, but only one is currently protected by under the law.
- The study’s author has recommended that all porcupines be categorized as protected species under Indonesian wildlife laws and listed under CITES to monitor the impacts of the trade on the wild population.
A startup deploys black soldier flies in the Philippines’ war on waste
- In Davao City, in the southern Philippines, a startup has introduced the use of black soldier flies (Hermetia illucens) to address kitchen waste.
- The flies are fed kitchen waste, turning the food waste into compost, while their larvae, rich in protein, is touted as alternative feed for livestock.
- Proponents say insect protein is a much better alternative than commercial livestock feed made with fishmeal, associated with depleting fish populations, or soybeans, linked to deforestation and extensive use of pesticides and fertilizers.
- Treating kitchen waste with black soldier flies is also being touted as a cleaner alternative to municipal plans to incinerate the waste to generate electricity, which would contribute to air pollution.
Decades of research back the value of marine reserves to Kenya’s fisheries
- A 24-year study conducted by Tim McClanahan looked at two different interventions to address unsustainable fishing practices in artisanal fisheries along Kenya’s coast: gear restrictions, and a marine reserve that prohibited all fishing activities.
- It found both methods showed an increase of catch per unit effort (CPUE), which indirectly measures the number of target species that were caught.
- Landing sites adjacent to the marine reserve maintained steady total yields, while the gear-restricted sites declined over the study period.
- While marine reserves were shown to generate more long-term benefits, outside experts say they are not always an ideal solution and that other approaches may be more appropriate in managing fisheries.
Earth tipping points could destabilize each other in domino effect: Study
- A new risk analysis has found that the tipping points of five of Earth’s subsystems — the West Antarctic Ice Sheet, the Greenland Ice Sheet, the Atlantic Meridional Overturning Circulation (AMOC), the El Niño–Southern Oscillation (ENSO) and the Amazon rainforest — could interact with each other in a destabilizing manner.
- It suggests that these changes could occur even before temperatures reach 2°C (3.6°F) above pre-industrial levels, which is the upper limit of the Paris Agreement.
- The interactions between the different tipping elements could also lower critical temperature thresholds, essentially allowing tipping cascades to occur earlier than expected, according to the research.
- Experts not involved in the study say the findings are a significant contribution to the field, but do not adequately address the timescales over which these changes could occur.
Bigger is badder when it comes to climate impact of farms in the Amazon
- A 20-year analysis of satellite data shows significant temperature differences in agricultural lands in southern Amazonia, depending on farm size.
- Extensively deforested commercial farms are up to 3 °C (5.4 °F) warmer than adjacent forests, while on smaller farms this difference is 1.85 °C (3.3 °F).
- Management practices that try to balance productivity with the maintenance of essential ecosystem services, such as the water cycle, will be crucial to preserving the Amazon’s remaining forests, the study’s authors say.
Climate change isn’t fueling algal blooms the way we think, study shows
- A team of international researchers recently published the first global assessment of harmful algal blooms (HABs) — events in which toxic algae proliferate and cause harm to marine life and humans — based on nearly 10,000 recorded events between 1985 and 2018.
- The study found that there are no global trends that would suggest that climate change is having a uniform impact on HABs throughout the world, although this is a commonly held belief.
- The researchers were able to detect clearer regional trends that showed increases, decreases or no significant changes in HABs in certain parts of the world.
- It also found that there was a perceived increase in HABs amid the booming aquaculture industry, although the study does not necessarily suggest that aquaculture is causing an increase in HABs.
What’s the cost of illegal mining in Brazil’s Amazon? A new tool calculates it
- The launch of a gold mining impacts calculator this week — a joint project of the Federal Public Ministry and the Conservation Strategy Fund — marks a big step forward in combating illegal mining in the Brazilian Amazon, experts and government agents say.
- The new tool was able to estimate damages of $431 million caused by illegal mining in 2020 on the Yanomami Indigenous Reserve, where local leaders have reported several attacks in the past month by miners, following an influx of mining activities since 2019.
- Since 2019, Brazil has exported $11 billion in gold, with Switzerland, Canada and the United Kingdom as the top importers; last year alone, these three countries imported $3.5 billion of the precious metal from Brazil.
- Improving traceability is another important step to cracking down on the environmentally devasting illegal gold market, says Sérgio Leitão, an expert in the fight against illegal mining in Brazil.
Study shows it took the Amazon as we know it over 6 million years to form
- An asteroid impact near Mexico 66 million years ago triggered an ecological catastrophe that claimed nearly half of all plant species and took Amazon forests more than 6 million years to recover from.
- Colombian researchers analyzed fossilized pollen and leaves and found plant diversity declined by 45% after the impact; when plant diversity finally recovered, open forests of ferns and conifers had been replaced by dense, closed-canopy forests dominated by flowering plants.
- The researchers suggested three interlinked explanations for the sudden transition: the extinction of large-bodied dinosaurs at the end of the Cretaceous reduced forest disturbance; dust from the impact acted as a fertilizer; conifers were more likely to go extinct.
- In the time periods studied, Earth’s climate was warmer and CO2 levels were higher, showing that climate alone is not enough to trigger a forest-to-savanna transition, with the pace of warming and deforestation the crucial puzzle pieces that determine whether today’s forests can survive.
On the Mongolian steppe, conservation science meets traditional knowledge
- Rangelands and the pastoralists who rely on them are an overlooked and understudied part of global conservation.
- Tunga Ulambayar, country director for the Zoological Society of London’s Mongolia office, says she wants to change this by complementing the scientific understanding with pastoralists’ traditional knowledge of nature.
- “There is no university teaching that kind of traditional knowledge, but if we really aim to care about these regions and their resources, even from an economic perspective, we need this knowledge,” she says.
- Ulambayar also notes that pastoralism, widely practiced in less industrialized countries, is increasingly recognized as an efficient system of resource management and a resilient culture.
To keep tabs on ecosystem health in Borneo, follow these birds: Study
- A recently published study has suggested looking at the wild populations of a key bird species as a gauge for ecosystem health in Borneo.
- The researchers found six Bornean bird species are strong indicators of intact forests, three species indicated the state of a depleted forest, one for mixed gardens, and none for oil palm plantations.
- The results endorse the general trend found across the tropics of a significant reduction in bird species richness, from complex natural and old secondary forest structures to simplified monoculture habitats.
- Borneo is considered a significant biodiversity evolutionary hotspot, but logging, mining and conversion to monoculture agriculture have drastically impacted its rainforests, and modified landscape structure through fragmentation and habitat loss.
Indonesian researchers study how to help rays released as bycatch survive
- Researchers in Indonesia are studying the survival rate of manta rays and devil rays released after being caught unintentionally by fishers.
- The study, which has so far tagged five of the animals with satellite trackers, aims to come up with best practices to boost the survival of these threatened rays.
- Populations of mantas and devils rays, from the genus Mobula, have been hit by the global trade of their parts, particularly their gills, for traditional medicine and food.
New paper urges shift to ‘nature positivity’ to restore Earth
- A new paper, published by leading conservationists and the heads of various global institutions, argues for adopting a “nature-positive” goal.
- This would require restoring the Earth from 2020, placing the world on a nature positive path by 2030 to mount a full recovery by 2050.
- According to the authors, nature positivity would provide an overarching goal for nature that would coincide with the Convention on Biological Diversity’s (CBD) mission and streamline agreements for climate, biodiversity, and sustainable development into one common vision.
- The paper was released a few days before the start of the meeting of the Subsidiary Body on Scientific, Technical and Technological Advice (SBSTTA), where parties will provide advice on the CBD’s post-2020 global biodiversity framework.
Absorbent and yellow and … mobile? Sea sponges on the move in Arctic Ocean
- A new study suggests that sea sponges are moving across the seafloor of the Arctic Ocean, which challenges the idea that these creatures are primarily immobile.
- Previous research has shown that sponges can make limited movements in a laboratory setting, but this is the first time sea sponge trails have been observed in the ocean and attributed to sponge movement.
- The researchers hypothesize that the sponges are moving to find food or disperse juveniles, although further research is needed before conclusions can be drawn.
Intimidation of Brazil’s enviro scientists, academics, officials on upswing
- Increasingly, Brazilian environmental researchers, academics and officials appear to be coming under fire for their scientific work or views, sometimes from the Jair Bolsonaro government, but also from anonymous Bolsonaro supporters.
- Researchers and academics have come under attack for their scientific work on agrochemicals, deforestation and other topics, as well as for their socio-environmental views. Attacks have taken the form of anonymous insults and death threats, gag orders, equipment thefts, and even attempted kidnapping.
- A range of intimidation is being experienced by officials, including firings and threats of retaliation for institutional criticism at IBAMA, Brazil’s environment agency, ICMBio, the Chico Mendes Institute of Biodiversity Conservation overseeing Brazil’s national parks, and FUNAI, the Indigenous affairs agency.
- “Whose interests benefit from the denial of the data on deforestation… from criminalizing the action of NGOs and environmentalists? What we are witnessing is a coordinated action to make it easier for agribusiness to advance into Indigenous territories and standing forest,” says one critic.
New map shows where the 80% of species we don’t know about may be hiding
- A new study maps out the regions of the world most likely to hold the highest number of species unknown to science.
- The study found that tropical forests in countries like Brazil, Indonesia, Madagascar and Colombia had the highest potential for undescribed species, mostly reptiles and amphibians.
- According to the lead researcher, the main reason for species going undescribed is a lack of funding and taxonomic experts in some parts of the world.
- He added that it’s essential to learn about as many species as possible to protect them, but that undescribed species are currently not taken into account by governing bodies like the UN’s Convention on Biological Diversity (CBD).
Ocean protection scheme can yield ‘triple benefits’ study says
- A new study suggests that carefully planned marine protected areas could yield triple benefits for the ocean, helping to maintain biodiversity, while also increasing fish yields and maximizing the ocean’s ability to sequester carbon in seafloor sediment.
- This study is one of the first to quantify the carbon footprint of ocean trawling, which it equates to the yearly emissions of the global aviation industry.
- The researchers suggest that the planning tools in this study could help inform discussions about how to protect 30% of the oceans by 2030, a goal that is expected to be adopted by the U.N. Convention on Biological Diversity later this year.
- Other proposals for how to achieve 30% protection by 2030 have mostly focused on the high seas, but this plan takes all parts of the ocean into consideration.
From penguins to sharks to whales, swimming in circles is a surprisingly common trait
- Many marine animals are intentionally swimming in circles consecutively at a relatively constant speed more than twice, according to a new study using data from movement trackers.
- The researchers say the behavior is surprising in part because swimming in a straight line is known to be the most efficient way to move about.
- They found some of the animals swim in circles during different activities, including foraging, courtship, navigation and even possibly geomagnetic observations.
Unrelated adoptions by bonobos may point to altruistic traits, study says
- Two wild bonobos in the Luo Scientific Reserve in the Democratic Republic of the Congo were observed to adopt infants from different social groups, according to a new study.
- These are said to be the first recorded cases of great apes adopting unrelated individuals.
- While the researchers do not know why these bonobos chose to adopt unrelated infants, they speculate that it could be to strengthen current and future alliances within their own groups as well as with other social groups.
On the sea’s surface, a wealth of ocean life gets its start, study finds
- A new study found that surface slicks — moving patches of smooth water that form on the sea’s surface — host an array of species in larval form off the west coast of Hawaiʻi Island.
- The researchers identified more than 100 fish species from 54 families inside these slicks, representing 10% of all fish species ever recorded in Hawaiian waters.
- Surface slicks play a pivotal role in the marine ecosystem by providing food and shelter for larvae, and transporting them into different parts of the ocean.
- In addition to larvae, surface slicks accumulate large quantities of plastic, which has been found to be infiltrating the food chain.
