Whales and dolphins at risk as report reveals ecological decline in Gulf of California
- The recent “Assessment of the Ecological Health of the Gulf of California” report shows a decline in several populations of animals throughout the narrow sea flanked by the Mexican mainland and Baja California.
- The report was compiled by the Next Generation Sonoran Desert Researchers (N-Gen) in the U.S. in collaboration with Prescott College’s Kino Bay Center field station in Mexico, and draws on long-term monitoring studies.
- Many of the assessed groups, such as seabirds, whales, giant squid, crabs, starfish and fish, are in decline.
- Basic primary productivity, which nurtures species diversity and abundance in the Gulf of California, remains stable.
15 years after the BP oil spill disaster, how is the Gulf of Mexico faring?
- The Deepwater Horizon disaster on April 20, 2010, was the largest offshore oil spill in U.S. history, releasing an estimated 4.9 million barrels of oil into the Gulf of Mexico over nearly three months.
- Fifteen years later, the gulf ecosystem shows a complicated picture of both resilience and lingering damage, with some species, like brown pelicans, recovering, while others, like humans, dolphins and deep-sea corals, continue to struggle with long-term health impacts.
- The disaster prompted an unprecedented legal settlement directing billions toward restoration projects, though experts debate whether these funds have been used effectively for ecosystem-scale recovery.
- Climate change remains the “800-pound gorilla in the room,” threatening the gulf’s future resilience, one expert said, with others warning that continued pressure from fossil fuel development, agricultural runoff and other threats could push the system beyond its capacity to recover.
Critically endangered right whales spotted in the Bahamas for first time
Two North Atlantic right whales, among the most at-risk marine mammals, were spotted swimming in the Bahamas on April 15, marking the first time the species has been seen in the nation’s waters. “That moment for me was breathtaking, and I couldn’t fully gather myself. I thought it was fake at first,” Isaac Ellis, a […]
Sheinbaum’s energy agenda under fire as Mexican activists slam LNG megaproject
- A controversial project bringing U.S. liquefied natural gas through the Mexican states of Chihuahua and Sonora to the Gulf of California continues to face strong resistance from environmental activists.
- Critics of the Saguaro energy project say the pipeline, associated infrastructure and increased industrialization will harm the biodiversity of the gulf, which hosts 85% of Mexico’s marine mammal species and one-third of the world’s dolphin and whale species.
- Energy analysts say the pipeline will increase Mexico’s dependence on U.S. fossil fuels and further delay energy transition goals, despite President Claudia Sheinbaum’s electoral promises to boost investments in clean energy.
- Environmentalists say they’re worried about the project’s greenhouse gas emissions, with methane being especially problematic due to its high global warming potential.
Icelandic whaling company calls off fin whale hunt this summer
Iceland’s largest commercial whaling company, Hvalur hf., has said it will not hunt any fin whales in the summer of 2025. In December 2024, Iceland’s government granted Hvalur hf., run by billionaire Kristján Loftsson, a five-year license to hunt 209 fin whales (Balaenoptera physalus) each year between 2025 and 2029. Another whaling company, Tjaldtangi ehf., […]
Study delves into increase in humpback whale sightings in UK and Ireland
Earlier this year, U.K. media reported an increase in humpback whale sightings in British and Irish waters. Between December 2024 and January, The Guardian reported some 17 sightings of humpback whales (Megaptera novaeangliae) from the Isles of Scilly in southwest England. Meanwhile, the nonprofit Sussex Dolphin Project reported more than 50 sightings from Sussex in […]
Counting whales by eavesdropping on their chatter, with help from machine learning
- Scientists have combined passive acoustic monitoring, machine-learning tools and aerial surveys to estimate the population of North Atlantic right whales in Cape Cod Bay.
- Using the method, researchers from Cornell University in the U.S. were able to estimate the daily population of the whales over a period of four months.
- While passive acoustic monitoring has helped scientists around the world detect the presence of whales, it’s often challenging to estimate population numbers from the data, especially for species like North Atlantic right whales that have highly variable call rates.
Whale songs rise and fall with food supply, study finds.
Each year, during summer and fall, large groups of baleen whales gather off the coast of California, U.S., to feast on krill and fish before heading south to breeding areas in the tropics. It’s a crucial time for whales to fatten up, and a new study suggests some whale species announce an abundance of food […]
Study suggests algal blooms disorient whales, putting them in danger
- Harmful algal blooms (HABs) in the ocean produce toxins that can sicken humans and marine animals.
- A new study has found an increase in large-whale deaths and injuries near HABs on the U.S. East and West Coasts, mainly due to ship strikes and entanglement in fishing gear.
- The authors propose the reason may be that HAB toxins disorient whales, decreasing their ability to avoid ships and fishing gear. However, they say more research is needed to confirm the link.
- They recommend using advanced HAB prediction models to reduce whale deaths by limiting activities like fishing when HABs and whales overlap.
Fishing boats spotted competing with whales in Antarctica for krill
Nearly all of Antarctica’s iconic wildlife, from penguins to seals and whales, depend on krill, tiny crustaceans that make up the base of the food chain. Krill are also sought after by humans, who scoop them up using massive fishing boats, potentially putting whales in danger, scientists warn. The fishing boats and whales are “going […]
Right whales can live to 130, but in North America they die young
- A new study indicates that right whales have extremely long lifespans of 130 years or more, adding to growing evidence of extreme whale longevity.
- The research draws attention to the plight of North Atlantic right whales, which are critically endangered. It found that despite their long potential lifespan, their actual lives are far shorter than those of southern right whales, a close relative.
- The authors and other experts believe North Atlantic right whales’ lives are being cut short due to threats in the “highly industrialized” waters off the eastern United States and Canada where they live; these include fishing gear, which can entangle the whales, and vessel strikes.
European Commission to review Greek oil activity permits in whale habitat
The European Commission will reportedly “seek clarification” from Greece about its recent approvals for offshore oil and gas activities in areas critical for threatened whales and sea turtles. That’s according to the NGO ClientEarth, which, alongside WWF Greece and Greenpeace Greece, filed a formal complaint with the European executive body in 2023 alleging that the […]
Hundreds of whales to be harpooned as Iceland issues new hunting licenses
- On Dec. 6, Iceland’s interim government announced it had issued five-year commercial whaling permits to hunt fin and minke whales.
- The permits, issued to domestic whaling companies Hvalur hf and Tjaldtangi, allow the hunting of 209 fin whales and 217 minke whales each year in Icelandic waters.
- The move follows recent government decisions to briefly pause whaling based on welfare concerns about using grenade-tipped harpoons for hunting, and then resume it again.
- Conservationists say the new whaling decision is a blow to marine conservation and question its timing by an interim government that’s soon due to hand over power to a coalition that isn’t pro-whaling.
Scientists, Māori experts uncover new insights into rare spade-toothed whale
- Spade-toothed whales (Mesoplodon traversii) are among the rarest and least-studied whales, partly due to their deep-diving behavior and long periods spent underwater in the vast, underexplored South Pacific Ocean.
- Until recently, only six records of spade-toothed whales had been documented over 150 years, all but one found in Aotearoa New Zealand, a known hotspot for whale strandings.
- The seventh and most recent record, a 5-meter (16-foot) male, stranded in New Zealand in July 2024, was recently dissected by scientists and Māori cultural experts at a scientific research center.
- A key finding was the presence of tiny vestigial teeth in the upper jaw, offering insights into the species’ evolutionary history, with further discoveries anticipated as analysis continues.
Colliding icebergs and chirping seals: Polar ocean sounds are reimagined in art-science collaboration
- The United Nations declared the 2020s the UN Decade of Ocean Science for Sustainable Development to highlight the need for public engagement, citizenship, and connection to harness positive change for the world’s seas.
- Art and science collaborations can make the hidden depths of the oceans come alive for people via creative pieces drawing from real marine research.
- Researchers in Germany and artists from around the world united to highlight the sounds of the polar oceans through art projects created with recordings from the Ocean Acoustics Group at the Alfred Wegener Institute.
Killer whales have found new homes in the Arctic Ocean, potentially reshaping marine ecology
- The vast ice sheets that historically kept killer whales out of the Arctic Ocean are melting as the region rapidly warms.
- Two small, genetically distinct groups of killer whales now live in the Arctic, after migrating from more southern regions of the Atlantic Ocean.
- Killer whales put pressure on the local ecosystem, including Arctic whales important to Indigenous groups.
Teamwork makes the dream work for orcas hunting world’s biggest shark
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 […]
‘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 […]
Protecting 2.6% of oceans could prevent deadly whale-ship collisions: Study
Ship strikes are a leading threat to large whales, with global shipping routes overlapping 92% of their habitats, a new study finds. But protecting whales in the most dangerous collision hotspots would require action over just 2.6% of the ocean’s surface, researchers conclude, potentially saving thousands of whales with minimal disruption to global trade. The […]
Near-extinct North Atlantic right whales get a small population boost
The population of the critically endangered North Atlantic right whale increased by five individuals, bringing the estimated total to 372 in 2023, according to an Oct. 22 report. The North Atlantic right whale (Eubalaena glacialis) population has declined since 2011. However, the slight rise in recent years may signal some stability for these ocean giants, […]
Social media influencers’ bad behavior with marine wildlife is risky for animals, too (commentary)
- Social media accounts which showcase close encounters with marine wildlife — from whales to white sharks and manta rays — have become common and popular.
- A distinctive feature of these is the presence of people in the images, where the focus is frequently on the individual near – or sometimes in direct contact with – the species: the main subject is not the animal itself but the human interacting with it, which puts both people and wildlife at risk.
- “In these experiences, what many of us often seek – a unique connection with a species different from our own – overlooks a fundamental principle: marine wildlife does not need our friendship, but rather our protection,” a new op-ed argues.
- This article is a commentary. The views expressed are those of the author, not necessarily Mongabay.
Fishing in a fog: Ship noise hampers orcas’ hunting success
Underwater noise from ships is making it tough for killer whales, or orcas, to find and catch their favorite fish, a recent study has found. Orcas (Orcinus orca) rely heavily on sound to hunt. They emit ultrasonic echolocation clicks that bounce off objects. By listening for the echoes of these clicks, the orcas can identify […]
Famous ‘spy’ beluga whale found dead in Norway
A beluga whale nicknamed Hvaldimir, who was initially suspected of being a Russian spy, was found dead on Aug. 31, according to Norwegian media. Hvaldimir’s body was first spotted by a father and son who were out fishing for mackerel near the port town of Risavika in southwestern Norway. “This morning, after receiving a sighting […]
Japanese ship hunts massive fin whale, country’s first in 50 years
Japanese commercial whalers recently killed their first fin whale in 50 years. The fin whale (Balaenoptera physalus), the world’s second-largest whale, after the blue whale (Balaenoptera musculus), can grow to up to 27 meters (88 feet) in length. Industrial whaling until the mid-1900s severely depleted their populations, and the species is classified as vulnerable to […]
Critically endangered North Atlantic right whale spotted near Ireland
A lone critically endangered North Atlantic right whale was recently photographed off the coast of Ireland, some 5,000 kilometers (3,100 miles) from its usual habitat in the western North Atlantic. It’s the first confirmed sighting there in several decades. There are an estimated 360 North Atlantic right whales (Eubalaena glacialis) today, living along the East […]
Anti-whaling activist Paul Watson arrested in Greenland
Prominent environmental activist Paul Watson has been arrested in Greenland, reportedly for his past interventions against Japanese whalers, according to a statement from his foundation. Watson, a Canadian-U.S. dual national, is the founder of Sea Shepherd, a U.S.-based nonprofit, marine conservation activist organization, and has been involved in several anti-whaling and anti-sealing protests in the […]
Icelandic government grants new license to whaling company to hunt 128 fin whales
- The Icelandic government has given a whaling license to commercial whaling company Hvalur for the 2024 season, allowing the company to hunt 99 vulnerable fin whales in the waters around Greenland and West Iceland and 29 around East Iceland and the Faroe Islands.
- In 2023, the government suspended Hvalur’s whaling operations due to animal welfare concerns, but the company recommenced whaling once the ban was lifted.
- The company’s license subsequently expired in 2023, but Hvalur reapplied for a license in January of this year.
- Animal welfare advocates have denounced the Icelandic government’s decision, arguing that whaling has no place in the modern world.
Indigenous Alaskans drive research in a melting arctic
- In Utqiagvik, Alaska, the Iñupiat rely on whaling and subsistence hunting for the bulk of their diet, a practice dating back thousands of years.
- Powered by mineral wealth, the Iñupiat-run North Slope Borough Department of Wildlife Management employs a collaborative team of scientists and hunters.
- Though the arctic is warming nearly four times faster than the global average, the Iñupiat are confident in their ability to adapt their practices to changing conditions.
- The Department of Wildlife Management provides a potential model for collaborations between Indigenous peoples and western researchers — with Indigenous leaders in charge of funding and resource allocation.
Report: Rising slaughter of small whales and dolphins threatens ocean balance
- Killings of small whales, porpoises and dolphins are rising, with more than 100,000 of these marine mammals slaughtered each year, according to a new report from German and British NGOs.
- Many regions report increased catches driven by demand for dolphin meat as food and shark bait in areas impacted by economic crisis and dwindling fish stocks.
- Failure to address unsustainable exploitation of small cetaceans exacerbates ecological imbalance and heavy metal toxicity risks to humans who eat them, according to the report.
- Insufficient legislation and enforcement remain critical issues, according to the report, which calls for international collaboration and stronger protection measures.
U.S. auctions off endangered whale habitat for oil and gas drilling
- On Dec. 20, the U.S. Department of the Interior’s Bureau of Ocean Energy Management (BOEM) held a lease sale to auction off oil and gas drilling rights in the Gulf of Mexico.
- Environmental groups and the U.S. Interior Department had tried to postpone this sale due to concerns about protecting the critically endangered Rice’s whale, a species whose key habitat overlaps with the lease sale areas.
- Scientists estimate there are fewer than 50 Rice’s whales left, and that the primary threat to the species is the oil and gas industry.
- While the lease sale went through without any protections for the Rice’s whale, environmental groups continue to explore legal and political avenues to ensure the species’ survival.
North Atlantic orcas reveal the troubling persistence of toxic ocean pollutants
- As the top predators in the ocean, killer whales suffer from the magnifying level of pollutants that build up in the marine food web.
- Scientists found that North Atlantic orcas feeding on marine mammals carry significantly higher levels of pollutants than orcas that eat fish.
- Levels of polychlorinated biphenyls in the orcas’ blubber are ten times higher than the toxic threshold for these dangerous household chemicals.
Lethal or not? Australia’s beaches are a crucible for shark control methods
- For decades, Australia’s east-coast states have attempted to keep beachgoers safe from sharks by deploying entangling shark nets and culling species deemed dangerous.
- Recent figures published by the state of New South Wales reveal that almost all the animals caught in the nets during the 2022/23 summer season were “nontarget” species, including turtles, dolphins and endangered shark species, the majority of which died due to entanglement in the nets.
- In contrast, the west-coast state of Western Australia has abandoned a shark culling regime in favor of nonlethal alternatives, such as drone monitoring and “eco barriers,” swimming enclosures that keep marine life out but do not risk entanglement.
- Despite calls from environmental groups to exclusively adopt nonlethal technologies, shark control programs are continuing in both New South Wales and its northern neighbor, Queensland, during the 2023/24 Australian summer.
Dominica set to open world’s first reserve centered around sperm whales
- The tiny island nation of Dominica has announced that it will create a 788-square-kilometer (304-square-mile) reserve to protect endangered sperm whales.
- Most of the sperm whales that live off the coast of Dominica are part of the Eastern Caribbean Clan, which currently has a population of fewer than 300 individuals.
- Sperm whales in this region are threatened by fishing gear entanglement, pollution, boat strikes, and even tourism.
- The new reserve aims to protect whales by restricting activities such as fishing, vessel traffic and tourism, while not entirely banning them.
As population ‘flattens,’ North Atlantic right whales remain at risk
- A new population estimate for North Atlantic right whales found about 356 individuals left in 2022, which suggests the population trend is “flattening.”
- In 2021, scientists previously estimated there were 340 right whales, although this number was later revised to 364 to account for several newborn calves.
- Despite there not being a notable difference between the population estimates in 2021 and 2022, scientists say North Atlantic right whales are still in danger of going extinct and that urgent measures need to be put into place to protect them.
Iceland’s whaling paradox (commentary)
- As Iceland’s latest whaling season comes to a close, a heated debate continues over the ethics and sustainability of the country’s policy on these marine mammals.
- Filmmaker and activist Micah Garen — who co-directed the documentary “The Last Whaling Station” — shares his thoughts on what may be the nation’s last whaling season.
- “The paradox of whaling is the inherent contradiction between a utilitarian and Kantian world view. If you believe your choices matter, then ending whaling now is the only ethical, moral and philosophical choice we can make,” he argues.
- This post is a commentary. The views expressed are those of the author, not necessarily of Mongabay.
International outcry as Iceland lifts ban on what could be last whale hunt
- The Icelandic government has announced that commercial whaling will recommence following a two-month suspension of the activity, albeit with increased monitoring and stricter hunting regulations.
- The government temporarily banned whaling in June due to animal welfare concerns, but the ban expired on Aug. 31.
- The decision to restart whaling has drawn criticism from environmentalists and animal rights advocates.
- Only one company in Iceland currently has a whaling license, and it’s set to expire this year, with no guarantee the government will renew it for the coming years.
Expected ship traffic to LNG Canada port could see whale deaths also rise
- The nutrient-rich ancestral waters of the Gitga’at First Nation in northern British Columbia are a critical habitat for fin, humpback and killer whales.
- The development of a $35.5 billion LNG terminal threatens these whales, as shipping traffic in the region is projected to surge, leading to more frequent encounters between whales and ships, a recent study warns.
- It uses whale movement data and predicted ship traffic modeling to conclude that two fin whales and 18 humpback whales could be killed each year in ship strikes in Gitga’at territorial waters.
- Researchers suggest mitigation measures like reducing ship speeds in whale hotspots and restricting ship traffic during August, when whales are most abundant in these waters.
Keep it down: U.N. report lists ways to reduce ocean noise pollution
- A new report published by the U.N.’s Convention on the Conservation of Migratory Species of Wild Animals (CMS) outlines possible solutions to human-caused ocean noise that impacts marine life.
- It focuses on three main types of underwater noise: shipping, seismic air gun surveys, and pile driving.
- Lindy Weilgart, the report author, said she believes it’s essential to move toward finding solutions rather than only studying the impacts of human-caused ocean noise.
- An outside expert praised the report but also questioned the likelihood of the suggestions being followed, and argued that the noise impacts of wind turbines have not been fully considered.
‘No future’: Iceland cancels whale hunt over animal welfare concerns
- Citing animal welfare concerns, Iceland has suspended its whale hunting season until Aug. 31.
- This decision follows the release of a government-commissioned independent report that found that many whales suffer immensely after being harpooned.
- Iceland had been set to kill around 200 fin whales, up from the 148 it killed in 2022.
Melting Arctic sea ice is changing bowhead whale migrations, study finds
- Research has found that some bowhead whales in the Bering–Chukchi–Beaufort (BCB) population are no longer migrating to the northwestern Bering Sea in the winter but remain in the Canadian Beaufort Sea.
- These migratory shifts are occurring as sea ice declines in the region due to climate change.
- These changes could mean that bowhead whales become more susceptible to ship strikes, underwater noise, and entanglements, and that Indigenous communities may not be able to rely on bowhead whales for nutrition and cultural subsistence.
- However, this bowhead population is currently not threatened, and these changes may not be fully impacting Indigenous communities yet.
How do you study one of the world’s rarest whales?
- Researcher Dana Wright is one of a handful of scientists studying one of the world’s rarest creatures, the North Pacific right whale.
- With about 500 individuals remaining, and its eastern population that swims off the coast of North America totaling perhaps 30 individuals, it’s so rare that in a decade of research, she has yet to see a living individual of the population, though her colleagues have.
- How does one study a creature that’s so hard to document? With tools like bioacoustics, for example, and Wright has listened to tens of thousands of hours of recordings to aid the conservation of these endangered animals.
- The team continues to develop new approaches to solving the mystery of these whales’ migratory patterns and biology with a goal of identifying — and then protecting — the location of their winter calving grounds.
New MPA Tic-Toc Golfo Corcovado a safe haven for blue whales in Chile
- Chile declared some 100,000 hectares (247,100 acres) in the Gulf of Corcovado in Northern Patagonia a marine protected area, the highest category of protection.
- The area is an important feeding and breeding ground for endangered blue whales as well as home to numerous other marine mammal species.
- However, it represents only a small fraction of the blue whales’ range, so scientists say additional conservation efforts must continue.
Climate change is exacerbating human-wildlife conflict, but solutions await: Study
- A review of 49 studies reveals that a variety of weather-related phenomena that are likely to become increasingly common due to climate change may increase human-wildlife conflict.
- The most commonly reported conflict outcomes were injury or death in people (43% of studies) and wildlife (45% of studies), and loss of crops or livestock (45% of studies). Many documented cases are occurring in the tropics, with animals such as Baird’s tapir (Tapirus bairdii) in Mexico, and elephants in Africa and Asia, increasingly coming into conflict with local communities.
- The impacts of climate change on human-wildlife conflict may especially affect vulnerable human populations, particularly when combined with pressures that limit mobility and flexibility in humans and animals. These stressors should be minimized where possible, researchers suggest.
- A better understanding of the climatic drivers of human-wildlife conflict could help prevent or alleviate conflicts. Predicting the onset of extreme weather events such as droughts, and proactively responding with temporary measures to protect animals and people, could be one effective solution, as could sharing information on how to avoid the hazards of wildlife conflict.
Recent seismic activity in Indian Ocean likely led pilot whales to beach on Sri Lanka shores
- Marine experts say the seismic activity in the Indian Ocean in the past few days likely pushed a pod of pilot whales onto Sri Lanka’s shores.
- Authorities and volunteers undertook a strenuous 15-and-a-half-hour operation to send a pod of pilot whales safely back into the sea.
- Rescuers managed to push 11 pilot whales back into the sea while three died on the shores.
- Recorded incidents of whales beaching up on Sri Lankan shores go back as far as 1889.
Potential impact on whales overlooked as deep-sea mining looks set to start, experts say
- Scientists say future deep-sea mining activities could impact cetaceans through noise pollution, which could interfere with their communication processes.
- According to an opinion piece, a team of experts say assessments of deep-sea mining impact have focused on species associated with the seabed rather than transitory megafauna that inhabit the proposed mining areas, and that urgent research is needed to understand the potential impact on cetaceans.
- However, a mining company says it is evaluating the potential impact of its proposed operations on cetaceans through the gathering of acoustic data during its recent mining test in the CCZ, which it will combine with three years of environmental baseline data.
- Deep-sea mining in international waters may begin later this year after the Pacific island nation of Nauru, which sponsors a subsidiary of a Canadian mining firm, requested accelerated approval of its mining operation.
U.S. refuses calls for immediate protection of North Atlantic right whales
- The U.S. government has rejected requests to implement emergency measures to protect critically endangered North Atlantic right whales from vessel collisions during the species’ calving season, which takes place between November and April each year.
- Some protections for right whales are already in place, but experts say urgent modifications are needed to protect pregnant females, lactating mothers and calves.
- There are only about 340 individual North Atlantic right whales left in the world, and birth rates are low.
- The National Marine Fisheries Service has proposed similar protections for right whales, including the enforcement of speed limits across more extensive areas of the ocean and for the rules to apply to more vessels — but charity workers are cautious about the outcome of this proposal.
Mexico dismantles illegal fishing cartels killing off rare vaquita porpoise
- At a press conference, a top navy official confirmed that the Mexican government has arrested members of criminal groups dedicated to illegally fishing totoaba in the Gulf of California.
- Totoaba bladders can go for as much as $80,000 per kilo, earning them the nickname “the cocaine of the sea.”
- Illegal totoaba fishing practices have contributed to the drastic population decline of vaquita, a small porpoise on the brink of extinction.
- Although the government’s arrests could slow the threats against the vaquita, other criminal groups are also interested in trafficking totoaba, suggesting that the fight to conserve marine populations in the gulf isn’t over.
Shipping lane change could be sea change for Sri Lanka’s blue whales
- Conservationists have welcomed an announcement by MSC, the world’s biggest container shipping line, that its ships will detour around a key feeding and nursing ground for blue whales off Sri Lanka’s southern coast.
- Ship strikes are a leading cause of death for the large whales that frequent the waters around Sri Lanka, which also include to a lesser extent sperm whales and Bryde’s whales.
- Marine conservationist Asha de Vos says other shipping lines should follow MSC’s lead, and has also called on the Sri Lankan government to propose making the shipping lane change permanent.
- She also says whale deaths from ship strikes may be up to 10 times higher than recorded, given that current and wind conditions are more likely to wash carcasses out to sea than toward shore, making them less likely to be detected.
Wrong trend for right whales amid ‘devastating’ population decline
- A newly released estimate suggests that only 340 critically endangered North Atlantic right whales remained as of 2021, a 2.3% decline from 2020, when the population numbered around 348.
- Fewer calves have been born in 2022 so far, corroborating research that suggests that North Atlantic right whale species are becoming less capable of reproducing.
- No adult mortalities have been recorded in 2022, but experts say that only about a third of whale deaths are recorded.
The mystery of narwhal behavior, solved by chaos theory
- Researchers have used mathematical models based on chaos theory to analyze the movements of a pod of satellite-tagged narwhals.
- Around solar noon, narwhals rest nearer the surface and take deep dives. At night, their dives are shallower but with more rapid and intense movement, likely to hunt for squid. Narwhal behavior also changed according to how much sea ice was present.
- The narwhal life cycle is closely linked to ice. Researchers say this new method may be useful for understanding the challenges narwhals and other Arctic animals face due to the loss of sea ice from climate change.
- Narwhals are among the most highly threatened animals in the Arctic due to hunting, predation, climate change, and the ships and noise pollution associated with oil and gas mining and exploration.
U.S. charts course for adopting ropeless fishing to reduce whale deaths
- The National Oceanic and Atmospheric Administration (NOAA) has published a report laying out a strategy to allow the use of “ropeless” or “on-demand” fishing gear off the U.S. East Coast with the goal of reducing entanglements of the critically endangered North Atlantic right whale.
- The gear uses acoustic signals to locate and retrieve gear, reducing the amount of time that vertical lines are present in the water column, where they can ensnare right whales and other types of marine life.
- Right whale numbers in the North Atlantic have declined precipitously in the past decade, as collisions with ships and entanglements have killed individuals and hampered the species’ ability to reproduce.
- NOAA’s Ropeless Roadmap estimates that on-demand fishing gear can substantially diminish the risk to right whales, while allowing economically and culturally important fisheries of the northeastern U.S. to continue.
New whale calls and dolphin behaviors discovered with bioacoustics
- On today's episode of the Mongabay Newscast, we take a look at two stories that show how bioacoustics research is helping us better understand the lives of marine mammals — and we take a listen to some of the recordings informing that research.
- Our first guest is Erin Ross-Marsh, the lead researcher behind a study of humpback whales at the Vema Seamount in the South Atlantic Ocean off the coast of South Africa. Ross-Marsh tells us about the study’s finding that these humpbacks were making gunshot calls, a type of non-song call that was previously unknown in these particular whales, and plays some humpback songs, non-song calls, and gunshot calls for us to listen to.
- We also speak today with Sarah Trabue, a research assistant with the Wildlife Conservation Society who is the lead author of a recently published paper detailing the findings of a bioacoustic study of bottlenose dolphins in and around New York Harbor. Trabue tells us what the study reveals about dolphin behavior in the highly trafficked waters around New York City and plays for us some of the dolphin vocalizations recorded as part of the study.
Noise pollution spooks whales the way predators would, study finds
- Whales appear to react to human-made noise in the ocean, such as naval sonar, in a similar way to which they respond to the sounds of their predators like killer whales, according to recent research.
- The authors of the study played the sounds of sonar and killer whales when whales from four species were present.
- The whales responded by breaking off their feeding forays, leading scientists to conclude that noise pollution in the ocean could leave them weaker and more vulnerable to predation.
- The researchers also suggest that marine mammals in the Arctic may be especially at risk as climate change alters their environment in ways that may make them more vulnerable.
What’s popping? Humpbacks off South Africa, new acoustic study finds
- Researchers recently recorded humpback whales making popping sounds like a gunshot at the Vema Seamount off the coast of South Africa.
- It’s not currently known why humpbacks make these sounds, but researchers suspect it has to do with mating or feeding.
- The Vema Seamount is an important feeding ground for humpbacks and other species, leading experts to call for the region to be protected.
That dead whale on the beach? Let it be, study says. Or at least don’t blow it up
- When marine mammals wash ashore, government agencies often set about removing the carcass.
- Strategies include burying the body, transporting it to a landfill or incinerator, towing it out to sea, and in at least one misguided case, detonating it.
- But in removing dead, stranded cetaceans from beaches, we may be overlooking the environmental benefits they offer, according to a new study.
- The researchers recommend leaving carcasses to rot in place whenever possible, where the environmental benefits they offer include supporting communities of scavengers, such as threatened species like polar bears and California condors.
‘There’s hope’ for North Atlantic right whales: Q&A with filmmaker Nadine Pequeneza
- The documentary “Last of the Right Whales” seeks to bring the plight of these gentle giants to audiences that are largely unaware of how close to extinction the species is today.
- North Atlantic right whales (Eubalaena glacialis) were historically decimated by hunting, but the biggest threats to the species today are ship strikes and entanglement in fishing gear.
- There are an estimated 336 of the animals remaining, more than 80% of which have experienced entanglement in ropes tethered to fishing gear on the sea floor.
- Documentary director Nadine Pequeneza spoke with Mongabay about bringing these threats to public attention, the importance of engaging with and not vilifying fishers, and why she holds out hope for the whale’s future.
In prioritizing conservation, animal culture should be a factor, study says
- Research has shown that culture exists in myriad animal species, allowing information to be shared between generations, leading to occurrences of tool use and potentially affecting animals’ adaptability to changes to their environment.
- In a new paper, scientists propose a stepwise process to account for and protect animal culture in conservation efforts.
- They advocate an approach to conservation that integrates culture with conventional considerations such as genetic diversity, rather than using it as a “stand-alone” tool.
Court order blocks Shell’s seismic surveys off South Africa’s Wild Coast
- A petition by environmentalists, Indigenous groups and fisheries organizations succeeded in temporarily halting oil giant Shell’s plans to conduct seismic surveys off South Africa’s Wild Coast to prospect for oil and gas reserves below the seabed.
- Conservation groups cited the potential impact on the breeding grounds of southern right whales and humpback whales, and the effect on the local fisheries sector.
- The recent order hinges on whether affected communities that hold traditional rights, including fishing rights in the waters, were properly consulted.
- The judge ruled that they were not, while also noting that concerns about irreversible harm to marine life were “reasonable.”
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.
Top 15 species discoveries from 2021 (Photos)
- Science has only just begun to find and describe all of the species on Earth; by some estimates, only 20% have been described.
- This year, Mongabay reported on newly described species from nearly every continent, including an Ecuadoran ant whose name broke the gender binary, an acrobatic North American skunk, an Australian “killer tobacco,” a fuzzy orange bat from West Africa, tiny screech owls from Brazil, and more.
- Though a species may be new to science, that doesn’t mean it has not yet been found and given a name by local and Indigenous communities.
Indigenous communities in South Africa sue, protest off-shore oil and gas exploration
- Thousands of South Africans, including Indigenous communities, mobilized in a national protest last Sunday against Shell’s planned seismic survey in search for oil and gas reserves off the country’s eastern Wild Coast – with more protests planned this weekend.
- Two court applications were submitted last week challenging the government’s license for oil and gas exploration, and demanded their constitutional right to a safe and healthy environment, as well as their Free, Prior and Informed Consent.
- Activists and communities fear the surveys and possible oil extraction will impact marine life and pollute coastal ecosystems which the Indigenous Xhosa rely on for their livelihood and traditional rituals.
- On Thursday, the Minister of Minerals Resources and Energy underlined the government’s support for oil exploration, criticizing environmental protesters for actions seen as “apartheid and colonialism of a special type.”
El Niño takes a toll on southern right whales in the Atlantic Ocean
- Southern right whale populations near Argentina have suffered surprising losses during recent El Niño years.
- Intense warmings in 1997-98 and 2015-16 each killed 4 to 5 percent of right whales in the southwest Atlantic Ocean, researchers estimate.
- If El Niño events worsen, models suggest the encouraging recovery of southern right whales could stall or even reverse.
Two threatened whale groups had a mini baby boom, but not because of lockdown
- Two rare whale groups — southern resident killer whales in the Pacific Northwest, and North Atlantic right whales — have had mini baby booms since the start of the pandemic, raising hopes about their survival prospects.
- But experts say a reduction in human activity during this period isn’t the cause, and that the underlying threats pushing these whales toward extinction still persist.
- North Atlantic right whales are threatened by fishing gear entanglement and ship strikes, while the southern resident killer whales have seen stocks of their favorite prey, the Chinook salmon, decline.
- Experts say that policies to protect the whales, including regulating shipping, closing fisheries and restricting certain types of gear, are not keeping pace with whales’ changing dynamics, and that changes might need to be applied throughout their range.
Faroe Islands to evaluate traditional hunt after slaughter of 1,400 dolphins
- The killing of 1,428 Atlantic white-sided dolphins in the Faroe Islands has sparked outrage among local people and attracted international criticism over the legitimacy of such hunts.
- The hunt was reportedly unauthorized and in violation of local Faroese law.
- In response, the Faroese prime minister announced that the government will evaluate the recent dolphin hunt as well as the tradition’s place in society.
Will ‘ropeless’ fishing gear be seaworthy in time to save endangered whales?
- Perhaps fewer than 360 North Atlantic right whales are alive today, according to researchers’ estimates.
- Scientists blame the declining population on the twin tolls exacted by ship strikes and entanglement in fishing gear.
- “Ropeless” fishing gear that minimizes the number of vertical lines in the water that ensnare right whales has emerged as a potential “home run” solution to the entanglement crisis.
- But fishers, industry groups and even ardent proponents of ropeless systems say that it’s not yet a viable replacement for traditional fishing gear in every situation.
It’s an ‘incredibly exciting’ time for the field of bioacoustics
- On this episode of the Mongabay Newscast, we look at why it's such an "incredibly exciting" time to be involved in the field of conservation bioacoustics — and we listen to some new and favorite wildlife recordings, too.
- Our guest is Laurel Symes, assistant director of the K. Lisa Yang Center for Conservation Bioacoustics at Cornell University's Lab of Ornithology. Symes tells us about how a new $24 million endowment will allow the center to expand its support for bioacoustics research and technology around the world and why this field is poised to make a huge impact on conservation.
- After our conversation with her, we listen to some of the most interesting bioacoustics recordings we've featured on the Mongabay Newscast, including the sounds of elephants, lemurs, gibbons, right whales, humpback whales, and frogs.
New ecolabel will certify ‘Whale-Safe’ shipping companies and cruise lines
- A new eco-label will certify freight and cruise companies that take steps to keep their ships from colliding with whales.
- To earn the label, companies must have 24/7 monitoring aboard their ships, share whale observation data through a digital platform, have procedures in place to act if a whale is sighted, and follow local speed and navigation rules.
- The challenge ahead is to persuade companies to sign up and comply — a task that will come down to pressure from customers and may be easier for some kinds of maritime companies than others, experts say.
Study confirms sightings of endangered blue whale in Philippine waters
- For years, a group of scientists have been tracking a mysterious whale that they initially labeled as belonging to another blue whale subspecies.
- Their decade-long efforts resulted in a new study that confirms the species as an endangered pygmy blue whale — an animal last recorded in Philippine waters in the 19th century.
- Researchers call the pygmy blue whale “Bughaw,” a Filipino word for the color blue.
- They say Bughaw’s presence could help establish Philippine waters as part of the extended migration path of the Indo-Australian population of pygmy blue whales.
Hunger, disorientation blamed for pilot whale mass stranding in Indonesia
- Indonesian officials have announced their findings into the cause of the mass stranding and death of 52 short-finned pilot whales earlier this year.
- They cited inflammation in the alpha whale’s echolocation organ as the cause of the stranding, and hunger and lung damage as the causes of death.
- The Indonesian fisheries ministry has called for more necropsies to be done more regularly after strandings to better understand these events and inform policies on how to handle them.
- Whale and dolphin strandings are common in Indonesia, which has the longest coastline in Asia and whose waters serve as both a habitat and an important migratory route for dozens of cetacean species.
Patagonia’s blue whales besieged by hundreds of boats, study finds
- Blue whales feeding off Chile’s north Patagonia coast have to dodge hundreds of vessels daily, most of them serving the area’s salmon farms.
- Marine traffic in the area is so intense that scientists have described it as a “neural network” of connections between salmon farms.
- The various impacts range from collisions, which can result in the death of whales, to noise pollution that prevents the whales from feeding properly.
- The researchers behind the study have called for measures to mitigate the vessel traffic intensity and be more mindful of the whales in the area.
‘Minke whales for dinner’: Norway’s controversial whale hunt is still on
- Norway has announced that it will target up to 1,278 common minke whales in its upcoming whaling season, which is the same quota as the past two years.
- While the Norwegian government says its whaling program is sustainable, some scientists, conservationists and animal welfare experts counter this claim.
- These anti-whaling advocates also point to a growing body of evidence that suggests that whales play a pivotal role in regulating the marine ecosystem, and that whales are worth more alive than dead.
- There has been a global moratorium on commercial whaling since 1986, but Norway chooses to reject this ban.
When Chinook salmon is off the menu, other prey will do for endangered orcas
- A new study has found that endangered southern resident killer whales mainly consume endangered Chinook salmon, but will broaden their diet when this species isn’t available.
- The researchers obtained data through prey and fecal waste collected from resident killer whales over a 13-year period.
- Efforts to reinstate Chinook salmon populations through hatchery efforts can play an important role in supporting resident killer whale populations, although these programs need to be carefully managed to ensure that stocks are diverse, the study suggests.
To fight climate change, save the whales, some scientists say
- In death, whales carry the tons of carbon stored in their massive bodies down to rest on the seafloor, where it can remain for centuries.
- Whale excrement fertilizes the ocean, producing large phytoplankton blooms that absorb enormous amounts of carbon dioxide.
- Scientists point out that helping whale populations recover from past overharvesting can help reduce greenhouse gas levels in the atmosphere.
Only 1 of 52 pilot whales survives mass stranding in Indonesia
- Two of the three whales that initially survived later became stranded again and died.
- Researchers are trying to determine the cause of the mass stranding, just the latest one in Indonesia.
Fewer than 100 of these giant whales make up a newly described species
- In January scientists announced the designation of a new whale species in the Gulf of Mexico they named Rice’s whale (Balaenoptera ricei).
- The team previously collected genetic samples of the whales but didn’t confirm the new species until they had a complete skeleton.
- Only between 33 and 100 individual members of the species exist, researchers estimate. The species is listed as endangered in the U.S.
- The Gulf of Mexico is fraught with many human-made threats to the whales’ survival, including dense ship traffic, oil and gas exploration, and marine trash.
Rare beaked whale sighting could be a world first for the species
- Researchers looking for elusive beaked whales in the South China Sea believe they spotted a pair of either the ginkgo-toothed or Deraniyagala’s beaked whale.
- Although they collected extensive observational data, they could not confirm the whales’ species without DNA samples.
- The sighting is nevertheless important: Knowledge of both beaked whale species has been limited to what researchers have learned from a handful of stranded whale carcasses and unconfirmed sightings.
- The encounter likely represents either the first ever live sighting of the ginkgo-toothed beaked whale (Mesoplodon ginkgodens), or the first live sighting of the nearly identical Deraniyagala’s beaked whale (Mesoplodon hotaula) in the western Pacific Ocean.
2020’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 2020.
- Hopeful developments this year included some long-overdue attention to Black and other underrepresented groups in marine science; new technologies to prevent deadly ship-whale collisions and track “dark” vessels at sea remotely; and surprising discoveries in the deep sea.
- At the same time, the COVID-19 pandemic resulted in more trash than ever being dumped in the sea, and stalled international negotiations aimed at protecting waters off Antarctica and in the high seas. 2020 also brought the first modern-day marine fish extinction.
- This post is a commentary. The views expressed are those of the authors, not necessarily Mongabay.
Whale of a find: Scientists spot beaked whale believed to be a new species
- Scientists on board a Sea Shepherd vessel say they found a new species of beaked whale near the San Benito Islands off Mexico’s Pacific coast.
- The species differs visually and acoustically from other beaked whales species, according to the researchers.
- The team took photographs, video recordings and acoustical recordings of the species, and also performed environmental genetic sampling to help confirm the existence of a new species.
- However, other experts say that detailed descriptions of the animals’ physical features and skeletal structure are needed before a new species can be accurately identified.
Can whales and dolphins catch COVID-19 from wastewater? It’s murky
- A new study identifies 15 marine mammal species, including whales, dolphins, seals and sea otters, that could be susceptible to the SARS-CoV-2 virus through contact with wastewater.
- According to the researchers, vulnerable populations of marine animals that congregate near wastewater discharge sites face elevated risks.
- To minimize these risks, the researchers suggest closely monitoring vulnerable populations for possible infection and vaccinating if necessary, and also restricting access to at-risk captive marine mammals.
- However, other experts say it is implausible for marine animals to get sick through contact with wastewater since virus transmission through water is unlikely.
Whale zone ahead: A cetacean speed trap tags ships going over the limit
- North Atlantic right whales, a critically endangered species with fewer than 366 remaining individuals, face two main threats: fishing gear entanglements and ship strikes.
- Many ships do not obey voluntary or mandatory speed restrictions in areas where North Atlantic right whales are present, raising the risk of fatal collisions.
- A new tool called Ship Speed Watch provides information on vessels that are not obeying speed restrictions.
- Conservationists say they hope it will help build awareness and strengthen regulations surrounding ship speeds.
Sri Lankans save pilot whales in epic rescue after mass stranding
- Volunteers braved a pandemic lockdown, darkness and risk of personal injury to help push over 100 short-finned pilot whales out to sea after they beached in southwestern Sri Lanka.
- The rescue effort, which involved towing the whales out using Jet Skis, ran overnight as the exhausted animals kept being washed ashore by the waves.
- In all, the rescuers managed to push back more than 100 whales, although at least five of the animals died.
- It was one of the largest mass strandings in Sri Lanka. Pilot whales are the cetacean group most susceptible to mass strandings, although the cause for the latest incident is still unclear.
‘No other choice’: Groups push to protect vast swaths of Antarctic seas
- A coalition of conservation groups is advocating for the establishment of three new marine protected areas (MPAs) in East Antarctica, the Antarctic Peninsula and the Weddell Sea, which would encompass 4 million square kilometers (1.5 million square miles) of the Southern Ocean, or 1% of the global ocean.
- These proposals will be discussed at an upcoming meeting of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), which is due to take place online because of the pandemic.
- Conservationists anticipate that China and Russia may not support these MPA proposals due to fishing interests in the region, although they are optimistic that the MPAs will eventually be approved.
New tool alerts ships when whales are near. But will they slow down?
- In 2018 and 2019 there were a record 27 documented whale-ship collisions off the coast of California, although the actual number is likely to be much higher.
- To reduce the number of deadly collisions, the Benioff Ocean Initiative launched Whale Safe on Sept. 17.
- The new mapping and analysis tool alerts mariners when whales are likely present in the busy Santa Barbara Channel near Los Angeles, drawing on data from an acoustic monitoring buoy, on-the-water sighting reports, and computer modeling.
- If whales are likely nearby, the developers hope large vessels will slow to speeds that are less harmful to whales in a collision. Their decision whether to do so remains voluntary.
Mauritians take to the street over oil spill and dolphin and whale deaths
- People gathered in the thousands in Mauritius’s capital, Port Louis, to protest the government’s response to a recent oil spill.
- The Japanese-owned freighter M.V. Wakashio crashed into the coral reef barrier off the island’s southeastern coast on July 25 and leaked about 1,000 tons of fuel oil into the sea near ecologically sensitive areas, before breaking in half a few weeks later.
- The stranding of at least 39 dolphins and whales near the site has sparked an outcry, though a link between the Wakashio shipwreck and the beachings has not yet been established.
- In a controversial move, the Mauritian government decided to sink the front half of the ship several kilometers away from the crash site in open waters, which some experts say could have impacted the dolphin and whale populations.
481 and counting: Norway’s whaling catch hits four-year high
- New data show that Norway has killed 481 minke whales so far this year, a number that surpasses the toll from the past three years.
- Norway continues its commercial whaling operation despite the International Whaling Commission placing a global moratorium on commercial whaling in 1982.
- While some whale meat and whale products are sold within Norway, the country also exports it to countries like Japan, Iceland and Denmark’s Faroe Islands.
- Whaling industry representatives say that whale meat sales have gone up in Norway during the COVID-19 pandemic, while conservationists and animal welfare advocates say that most Norwegians are not interested in consuming whale meat.
Singing and whistling cetaceans of southern Africa revealed by bioacoustics
- On today’s episode of the Mongabay Newscast we’re taking a look at two examples of how bioacoustics studies have discovered things we never knew before about marine life.
- Dr. Tess Gridley joins us to talk about the recent discovery of singing humpback whales in South Africa’s False Bay. Gridley plays us some of the recordings she and her team made documenting humpback songs in False Bay for the first time ever, and discusses the African Bioacoustics Community’s upcoming conference, which she hopes will help inspire even more bioacoustic research focused on African wildlife.
- We’re also joined by Sasha Dines, a PhD student at the University of Stellenbosch who is studying humpback dolphins. Dines’ work is focused on determining whether or not Indian Ocean humpback dolphins make signature whistle calls, which could be used to monitor the dolphins’ via passive acoustic monitoring arrays. She plays us some whistle calls of a humpback dolphin named Herme, and explains how bioacoustic monitoring could help improve not just monitoring but also conservation efforts for these endangered dolphins.
To flourish, Sri Lanka’s whale-watching industry must operate responsibly (commentary)
- Whale watching in Sri Lanka picked up in 2005, and the end of the civil war in 2009 ensured wider access to some of the finest coastal beaches in the Indian Ocean island.
- Expeditions that highlighted Sri Lanka as one of the top whale-watching destinations sparked an ever-expanding industry, giving rise to concerns about irresponsible public conduct and the need to minimize harm to marine mammals.
- In response, awareness-raising initiatives are being taken by various groups with emphasis on responsible whale watching according to existing guidelines and codes of conduct.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.
Narwhals beware: Killer whales are on the rise in the Arctic
- Climate change has led to dramatic ice loss in the Arctic, allowing killer whales to access parts of the Canadian Arctic they previously couldn’t.
- A new study found that a population of 136 to 190 killer whales spent the warmer summer months in Canada’s northern Baffin Island region between 2009 and 2018, and preyed on as many as 1,504 narwhals each season.
- While the overall narwhal population isn’t in immediate danger, a steady influx of killer whales could lead to ecosystem transformation through a top-down trophic cascade, according to the study.
Animals have culture, too, and for some it’s crucial to their survival and conservation
- On today's episode of the Mongabay Newscast we explore animal culture and social learning with author Carl Safina and whale researcher Hal Whitehead.
- Carl Safina examines the capacity of several animal species for social learning and transmitting knowledge across generations in his new book, Becoming Wild: How Animal Cultures Raise Families, Create Beauty, and Achieve Peace. Safina appears on the Mongabay Newscast today to explain how sperm whales, scarlet macaws, and chimpanzees are equipped to live in the world they live in as much by what they learn from other individuals in their social groups as by their genetic inheritance.
- Hal Whitehead, a professor at Canada’s Dalhousie University, was one of the first scientists to examine the complex social lives of sperm whales and the distinctive calls known as codas that they use to establish their group and personal identities. He appears on the podcast today to play us some recordings of sperm whale codas and tell us about sperm whale culture and social learning.
Baby humpback whales bulk up in Hawaii ahead of migration [VIDEO]
- New video reveals baby humpback whales nursing in Hawaii, a sight rarely seen by humans.
- A team of researchers used non-invasive suction cups to outfit seven baby humpback whales with special tags for recording data on nursing as well as other whale behaviors.
- During their time in Hawaii, the whale calves must drink enough milk to fatten up for a one to two-month migration back to Alaska.
- The researchers hope to understand the needs of mother whales and their calves during their time in the tropical breeding grounds and for their long migration.
Economists put a price tag on living whales in Brazil: $82 billion
- Last year, a team of four economists published a report suggesting that living whales have a high market value for the services they provide in terms of ecotourism, carbon sequestration, and fishery enhancement. Each whale is worth about $2 million USD, they estimated.
- The economists, in collaboration with two conservation organizations, Instituto Baleia Jubarte and the Great Whale Conservancy, estimated that Brazil’s whale population is worth $82 billion.
- The team says it hopes the notion of valuing whales in Brazil, as well as in other coastal nations, can help protect whales from common fatalities like ship strikes, fishing gear entanglement, and deliberate hunting.
Researchers miss out on sperm whale superpod in Sri Lanka amid pandemic
- Since 2010, researchers have recorded sperm whale aggregations, or superpods, consisting of hundreds of the giant mammals in the waters off Sri Lanka from late March to early April.
- Researchers missed out on the narrow window to observe this year’s spectacle, as the COVID-19 pandemic forced a nationwide shutdown; they also failed to carry out all scheduled workshops teaching tour boat operators about responsible whale-watching.
- Restrictions in response to COVID-19 have had similar impacts in other countries as well, disrupting planned field research.
Iceland won’t be killing any whales this year
- An Icelandic whaling business, IP-Utgerd, has announced that it will stop whaling altogether, while the largest whaling company in the country, Hvalur hf., has halted its whaling operations for the second year in a row.
- IP-Utgerd and Hvalur continued to whale in spite of the International Whaling Commission (IWC) placing a global moratorium on whaling in 1986.
- Conservationists say they hope that whaling ends permanently in Iceland, although it’s possible that Hvalur will resume hunting whales again in the near future.
Decade after BP Deepwater Horizon spill, oil drilling is as dangerous as ever
- Ten years ago, the BP Deepwater Horizon exploratory rig exploded, killing 11 people and initiating the largest oil spill in the history of the United States.
- Nearly 5 million barrels of oil spilled into the Gulf of Mexico, causing catastrophic damage to the ecosystem and economy of the region.
- A newly published report by the nonprofit Oceana looks back at how this spill happened, the resulting ecological and economic impacts, and if this catastrophe has changed government or oil industry approaches to offshore drilling.
- Poor government oversight and inadequate safety culture paved the way for the BP Deepwater Horizon explosion. Now, a decade later, it appears these conditions, the prerequisites for disaster, have not improved.
Chile: Expedition to the end of the world, where humpback whales are thriving
- Mongabay Latam joined an expedition to the Francisco Coloane Marine Park near the southern tip of Chile, where the humpback whale population has risen dramatically — from 40 individuals in 2003 to 190 in 2019.
- The park, established in 2003, remains without a management or administrative structure, but that is changing with the development of a conservation and sustainable development plan underway.
- Although the whale population in the area is growing, threats remain, including entanglement in fishing gear, contamination from nearby salmon farms and ship traffic and noise pollution from coal mines.
Songs and sounds of Bering Sea whales and seals reveal a story of change
- On today’s episode of the Mongabay Newscast, we listen to recordings of marine mammals in the Arctic with Dr. Howard Rosenbaum, the director of the Wildlife Conservation Society’s Ocean Giants Program.
- Rosenbaum co-authored a recent study that used bioacoustics to better understand how seasonal variation in sea surface temperatures and sea ice extent affect populations of five species of endemic Arctic marine mammals: bearded seals, beluga whales, bowhead whales, ribbon seals, and walrus.
- We listen to recordings of marine mammals used in the study as well as recordings of ships: Rosenbaum joins us to discuss how those ship sounds can affect Arctic wildlife and how the results of the study will help scientists track the impacts of climate change on Arctic ecosystems.
New right whale protection measures announced by Canadian government
- Canada has announced new protection measures for North Atlantic right whales, which face severe threats to their survival due to human activities off the Atlantic Coast of North America.
- Most recent right whale deaths have occurred in Canadian waters, which scientists attribute, at least partly, to the fact that the whales have moved into areas where there were no regulations in place to address threats like ship strikes and entanglement.
- Scientists say the new regulations proposed by the Canadian government are encouraging. Meanwhile, if the Trump Administration gets its way, the United States will be moving in the exact opposite direction on protections for whales in its waters.
In Chile, scientists seek the cause of blue whales’ mystery skin lesions
- Blue whales in Chile have been plagued with serious skin lesions, blister-like sores that can cover their whole bodies.
- Following a study that confirmed the presence of persistent organic pollutants in the bodies of blue whales in southern Chile, a second study is underway to determine the cause of the lesions.
- Although the results of the second study have yet to be released, scientists believe the lesions could be linked to commercial salmon farming.
Bid to get ‘aquatic wild meat’ off the menu and under protection
- The term “aquatic wild meat,” or “marine bushmeat,” refers to the hunting of marine mammals, reptiles, seabirds and now some sharks and rays.
- The hunting takes place all over the world and has increased in recent years as small-scale fishers have lost access to fish and other marine resources.
- Last week, delegates representing more than 80 countries took steps to address the issue of aquatic wild meat at the Convention on the Conservation of Migratory Species of Wild Animals conference in Gandhinagar, India.
- Other outcomes of the conference included adding 10 new species to the convention’s protected lists, including the jaguar and Asian elephant, recognizing the culture of wild animals, and calling for migratory species to be considered in national climate and energy policies.
Beaked whales’ stealth behavior gives clues to mystery of mass stranding
- A new study suggests that beaked whales have evolved stealthy and synchronized behavior to evade predators such as killer whales.
- They dive in synch to maximize their foraging time together and minimize their time at the surface, where killer whales can more easily target them.
- And even though they depend on echolocation to communicate and forage, they go into silent mode in depths that killer whales typically hunt in.
- Predator avoidance is such a strong driver of their behavior that researchers say any hint of danger —even a naval sonar — could trigger an intense stress response, and possibly explain why beaked whales are prone to mass stranding.
Key cetacean site in Philippines sees drop in dolphin, whale sightings
- A recent survey has confirmed a declining trend in sightings of dolphins and whales in the Tañon Strait in the central Philippines, a waterway declared an Important Marine Mammal Area by the IUCN.
- The strait is a migratory route for at least 11 cetacean species, including the vulnerable Gray’s spinner dolphin and the endangered false killer whale, but four surveys carried out since 1999 have shown a sharp decline in population and species sightings.
- One bright spot in the latest survey was the sighting of rose-bellied dwarf spinner dolphins, only the second time that the species has ever been spotted in Philippine waters.
- The strait is one of the country’s busiest sea lanes, encountering heavy fishing and tourism activities, which researchers say may be a factor for the downward trend. They call for further collaboration to enact stringent measures on fishing and tourism activities to protect the area.
2019’s top 10 ocean news stories (commentary)
- Marine scientists from the University of California, Santa Barbara, share their list of the top 10 ocean news stories from 2019.
- Hopeful developments included progress toward an international treaty to protect biodiversity on the high seas and a rebound in the western South Atlantic humpback whale (Megaptera novaeangliae) to nearly its pre-whaling population size.
- Meanwhile, research documenting rapidly unfurling effects of climate change in the ocean painted a dire picture of the present and future ocean. These include accelerating sea level rise, more severe marine heatwaves and more frequent coral bleaching events.
- This post is a commentary. The views expressed are those of the authors, not necessarily Mongabay.
The best animal calls featured on the Mongabay Newscast in 2019
- This is our last episode of 2019, so we took a look back at the bioacoustic recordings we featured here on the Mongabay Newscast over the past year and today we will be playing some of our favorites for you.
- As regular listeners to the Mongabay Newscast already know, bioacoustics is the study of how animals use and perceive sound, and how their acoustical adaptations reflect their behaviors and their relationships with their habitats and surroundings. Bioacoustics is still a fairly young field of study, but it is currently being used to study everything from how wildlife populations respond to the impacts of climate change to how entire ecosystems are impacted by human activities.
- On today’s episode, we listen to recordings of stitchbirds in New Zealand, river dolphins in Brazil, humpback whales in the Pacific, right whales in the Atlantic, and gibbons in Indonesia.
Orca grandmothers help improve survival odds of their grandkids, study finds
- Grandmother orcas that are no longer breeding help improve their grandcalves’ chances of survival, a new study has found.
- By analyzing the lives of 378 orca grandchildren in two resident groups in the Northeast Pacific, the researchers found that calves whose maternal grandmother died within the last two years had a mortality rate 4.5 times higher than a calf with a living grandmother.
- The effect was particularly amplified when salmon populations, which resident pods rely on, were low, the authors found, and less so when salmon was abundant.
- Since elderly females lead younger members of their group to salmon hotspots in the ocean, and salmon populations are declining in general, the study highlights grandmothers’ crucial role in the survival of the mammals.
Canaries in the coal mine? North Atlantic right whale use of key habitat changing rapidly
- A team of researchers with the Center for Conservation Bioacoustics at the Cornell Lab of Ornithology and Syracuse University recently published the results of a six-year study that focused on the North Atlantic right whales (Eubalaena glacialis) in Massachusetts Bay, which, together with Cape Cod Bay, comprises one of seven areas in the Gulf of Maine that the whales use during seasonal congregations.
- The team used an automated detection algorithm to determine the presence of right whale “up‐calls” in 47,000 hours of recordings made with 19 bioacoustic recording devices deployed across 4,000 square kilometers (about 1,544 square miles) of Massachusetts Bay.
- The number of whales present during the peak season increased every year of the study except for 2009-2010, “when acoustic presence was unusually low,” according to the study. But the researchers also detected an increased presence of right whales during parts of what should be their off‐season, from late summer to early fall. That could have serious implications for efforts to conserve the species.
Last of the belugas from Russia’s ‘whale jail’ released
- Late last year, drone footage revealed 87 belugas and 11 orcas packed in cramped, icy pens at Srednyaya Bay in Russia’s Far East.
- Following international outrage, Russian authorities began an investigation and started releasing the whales to the Sea of Okhotsk, the place the mammals had been originally captured from.
- On Nov. 10, Russian authorities announced that the last of the 50 beluga whales had been released to Uspeniya Bay, in the Primorsky Region, about 62 miles away from the holding facility. But it’s not the whales’ native habitat, conservationists say.
- Activists and conservationists have criticized the lack of transparency in the release effort and the manner in which the whales have been moved to the sea without a proper rehabilitation process in place.
There’s a new fin whale subspecies in the North Pacific
- The northern fin whale subspecies was previously believed to include populations in the North Atlantic and North Pacific oceans, but a recent genetic analysis of more than 150 fin whale samples from both ocean basins and the Southern Hemisphere showed that the two populations actually qualify as two separate subspecies.
- By comparing DNA from fin whales in the North Pacific and the North Atlantic, researchers determined that the populations have been genetically distinct for hundreds of thousands of years.
- Improving our understanding of fin whale taxonomy can have important implications for the conservation of the species, which is listed as Vulnerable on the IUCN Red List.
Once close to extinction, western South Atlantic humpback population close to full recovery
- According to a study published in the journal Royal Society Open Science last week, there were nearly 27,000 western South Atlantic humpbacks as of 1830, but the population was reduced by some 95 percent, to just 450 whales, by the mid-1950s. In the 12 years between 1904 and 1916 alone, the population lost approximately 25,000 individuals.
- Protection measures for humpbacks adopted in the 1960s and the broader moratorium on all commercial whaling adopted by the International Whaling Commission (IWC) in the 1980s appear to have reversed that downward trajectory, however. There has been no hunting of the species since 1972, the report states, which is when the recovery really took off.
- “Once protected, [western South Atlantic] humpback whales have recovered strongly, and their current abundance is close to 25,000 whales,” the authors of the study write. That means that the current population is estimated to be at 93 percent of its numbers prior to the exploitation by whalers that nearly extirpated the entire population.
Expedition finds new humpback breeding ground and sends first deep divers to Amazon Reef
- A number of marine species, from whales and dolphins to sea turtles and sharks, are known to migrate through the waters off the coast of French Guiana, the same biodiversity-rich waters that harbor the Amazon Reef, which was discovered in 2016.
- Scientists with the French Centre National de la Recherche Scientifique (CNRS) onboard the Greenpeace ship Esperanza discovered and documented humpbacks as well as tropical whale species feeding and breeding in the area, which they say is a first.
- As part of the same expedition, the first dives down to the Amazon Reef were undertaken in order to document the reef ecosystem via high-resolution photography and collect biological samples.
Humpback whales across the Pacific Ocean are singing the same song
- On today's episode of the Mongabay Newscast, we speak with Jim Darling, a marine biologist who is here to play us some recordings of remarkably similar humpback whale songs from around the world.
- Darling and colleagues found that North Pacific humpback whale songs can be incredibly similar to each other — nearly identical, in fact. That means that our view of the whales as living in distinct groups might very well be wrong. And that view dictates a lot of the conservation measures we’ve designed to protect imperiled populations of humpbacks.
- Darling joins us today to talk about his humpback research and play us some of those recordings so you can hear the similarity for yourself.
Baby whale wears a camera, reveals its travel and nursing behavior: video
- A video taken by a camera carried by a baby whale shows underwater nursing behavior from the calf’s perspective.
- The CATS Cam camera used in the filming incorporates multiple environmental sensors, such as depth and temperature, as well as movement and acceleration by the calf.
- The unusual perspective may help researchers better understand the nursing process of a baby whale, including surfacing to breathe while its mother remains underwater and suckling from mammary slits on each side of its mom.
Listen to the first-ever recordings of right whales breaking into song
- On this episode of the Mongabay Newscast, we speak with Jessica Crance, a research biologist with the US National Oceanic and Atmospheric Administration (NOAA) who recently discovered right whales singing for the first time ever.
- Gunshot calls made by right whales are exactly what their name suggests they are — loud, concussive bursts of noise. Perhaps that doesn’t sound terribly musical, but the critically endangered eastern population of North Pacific right whales appears to use gunshot calls in a repeating pattern — the first instance ever recorded of a right whale population breaking into song.
- Jessica Crance led the research team at NOAA that documented North Pacific right whales breaking into song in the Bering Sea. On this episode of the Mongabay Newscast, Crance will play recordings of two different right whale song types and discuss what we know about why the critically endangered whales might be singing in the first place.
Japan resumes commercial whale hunting
- For years, Japan exploited a loophole in international rules to continue hunting whales despite being a member of the International Whaling Commission (IWC) bound by the commercial whaling moratorium that went into effect in 1986. The country has now quit the IWC altogether and resumed commercial whaling.
- The first minke whale caught under the country’s new commercial whaling program was landed yesterday at Kushiro port in northern Japan, according to the Environmental Investigation Agency, a London-based NGO.
- IWC members Norway and Iceland are the only other countries on Earth that currently hunt whales commercially. But Iceland’s two whaling companies have announced that they’ll be sitting out the summer 2019 whaling season, meaning that, for the first time in 17 years, no whales will be caught in Iceland’s waters.
Six endangered North Atlantic right whales died last month alone
- In June this year, six endangered North Atlantic right whales were spotted dead in Canadian waters, including a 40-year-old breeding grandmother, and a 34-year-old grandfather.
- With only some 400 North Atlantic right whales (Eubalaena glacialis) estimated to survive today, researchers and conservation groups are worried.
- Necropsies carried out so far suggest that some of the whales died from collisions with ships.
- Entanglement in fishing gear is another leading cause of death among this extremely threatened species of baleen whale.
Researchers discover right whales singing for the first time ever
- Right whales — three species of large baleen whales in the genus Eubalaena — have never been known to sing. As far as scientists knew, right whale vocalizations consisted entirely of individual calls, as opposed to the repeated, patterned phrases of true whale songs.
- But according to a study published in The Journal of the Acoustical Society of America this month, the extremely rare eastern North Pacific right whale appears to use its gunshot calls in a repeating pattern — the first instance ever recorded of a right whale population breaking into song.
- A research team with the US National Oceanic and Atmospheric Administration (NOAA) analyzed 17-years’-worth of data from autonomous recorders deployed in the Bering Sea and documented four distinct right whale song types at five different locations between the years 2009 and 2017.
Canada passes ‘Free Willy’ bill to ban captivity of all whales, dolphins
- On June 10, Canada’s House of Commons passed a bill that bans the practice of keeping cetaceans (whales, dolphins and porpoises) in captivity in the country.
- Bill S-203 also prohibits breeding of the animals and collecting reproductive materials from them. The only exceptions to these provisions will be in cases of rescues and rehabilitation, licensed scientific research, or “in the best interests of the cetacean’s welfare.”
- The legislation, also known as the “Free Willy” bill, allows Vancouver Aquarium and Marineland in Niagara Falls, the only two facilities in Canada that still house cetaceans, to continue to keep their animals as long as they do not breed or bring in any new individuals.
New pilot whale subspecies revealed: Q&A with marine biologist Amy Van Cise
- For centuries, Japanese seafarers have noted two distinct types of pilot whale in their waters: One with a squarish head and dark body, the other a bit bigger with a round head and a light patch on its back.
- The two types have long been officially classified simply as forms of the same species, short-finned pilot whales (Globicephala macrorhynchus), but a new genetic study finds that they are actually distinct subspecies.
- The finding is just the latest shake-up of the cetacean family tree after the discoveries of new whale species in recent years.
- Mongabay spoke with the new study’s lead author, Amy Van Cise, a marine biologist at Woods Hole Oceanographic Institution in Massachusetts, about the science of whale taxonomy and what her team’s discovery means for the conservation of short-finned pilot whales.
Chatty river dolphins in Brazil might help us understand evolution of marine mammal communication
- On today’s episode of the Mongabay Newscast, we speak with Gabriel Melo-Santos, whose study of Araguaian river dolphins in Brazil has revealed that the species is much chattier than we’d previously known — and could potentially help us better understand the evolution of underwater communication in marine mammals.
- The Araguaian river dolphin was only described to science in 2014, and there’s a lot we don’t yet know about the freshwater cetacean species. It was believed that the solitary nature of the dolphins meant that they wouldn’t have much use for communication, but Gabriel Melo-Santos led a team of researchers that recorded 20 hours of vocalizations and documented 237 distinct types of sounds made by the dolphins.
- In this Field Notes segment, Melo-Santos plays some of the recordings he’s made of Araguaian river dolphins, explains how he managed to study the elusive creatures thanks to their fondness for a certain fish market in Brazil, and discusses how the study of Araguaian river dolphin vocalizations could yield insights into how their sea-faring relatives use their own calls to maintain social cohesion.
The health of penguin chicks points scientists to changes in the ocean
- A recent closure of commercial fishing around South Africa’s Robben Island gave scientists the chance to understand how fluctuations in prey fish populations affect endangered African penguins (Spheniscus demersus) absent pressure from humans.
- The researchers found that the more fish were available, the better the condition of the penguin chicks that rely on their parents for food.
- This link between prey abundance in the sea and the condition of penguin chicks on land could serve as an indicator of changes in the ecosystem.
’Unprecedented’ loss of biodiversity threatens humanity, report finds
- The U.N.’s Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services released a summary of far-reaching research on the threats to biodiversity on May 6.
- The findings are dire, indicating that around 1 million species of plants and animals face extinction.
- The full 1,500-page report, to be released later this year, raises concerns about the impacts of collapsing biodiversity on human well-being.
Killer whale vs. great white? No contest — the shark always flees
- Both the great white shark and the killer whale or orca are fearsome top predators. But of the two massive animals, the killer whale may be the more formidable one, a new study has found.
- Researchers monitoring white sharks, lion seals and orcas around California’s Southeast Farallon Island have found that every time orcas pass through the area, the great white sharks vanish and don’t return to their hunting grounds until the next season.
- The researchers aren’t sure why the sharks move away as soon as orcas arrive. It could be because orcas may be targeting white sharks as prey, or the killer whales could be bullying their competition out of the way to gain access to the island’s elephant seals.
Swelling amount of plastic in the ocean confirmed by new study
- A new study used log books from 60 years of plankton research to document the increase in the amount of plastic in the ocean.
- The study’s authors tabulated the entanglements of the continuous plankton recorder, a sampling device that’s towed behind ships, revealing a significant increase in plastic in the ocean since the 1990s.
- Scientists have long suspected such a trend but have been unable to demonstrate it with data until now.
Omura’s whale much more widespread across the globe than previously thought
- The global range of the world’s most recently discovered large whale species is starting to come into focus — as are the man-made threats to the species.
- Salvatore Cerchio of the New England Aquarium in Boston, Massachusetts led a team that published a paper in Frontiers in Marine Science in March that includes a map of all known sightings of the elusive Omura’s whale (Balaenoptera omurai), demonstrating that the whale has a much larger range than previously thought.
- Given the new information they had about the global range of Omura’s whale, the researchers determined the whales face threats from, “at minimum, ship strikes, fisheries bycatch and entanglement, local directed hunting, petroleum exploration (seismic surveys), and coastal industrial development.”
Scientists urge overhaul of the world’s parks to protect biodiversity
- A team of scientists argues that we should evaluate the effectiveness of protected areas based on the outcomes for biodiversity, not simple the area of land or ocean they protect.
- In a paper published April 11 in the journal Science, they outline the weaknesses of Aichi Biodiversity Target 11, which set goals of protecting 17 percent of the earth’s surface and 10 percent of its oceans by 2020.
- They propose monitoring the outcomes of protected areas that measure changes in biodiversity in comparison to agreed-upon “reference” levels and then using those figures to determine how well they are performing.
Russia plans to release nearly 100 belugas, orcas from icy ‘whale jail’
- Russian authorities have announced that they will release all 97 whales currently being held captive in Russia’s Far East.
- The whales made news in November last year when an aerial drone video showed several of them cramped inside small, rectangular sea pens at Srednyaya Bay, which the local media labeled a “whale jail.”
- The initial video showed some 90 belugas and 11 killer whales or orcas in the pens, caught by four companies that allegedly planned to illegally sell the animals to Chinese aquariums and amusement parks. Experts believe some of the whales may have since died.
Crab season to be cut short in California to protect whales and turtles
- A settlement between the Center for Biological Diversity and the California Department of Fish and Wildlife will close California’s Dungeness crab fishery three months early in 2019 to reduce the chances that whales and other sea life will become entangled in fishing gear.
- The crabbing season in 2020 and 2021 will also be shuttered early in places where high concentrations of whales come to feed in the spring, such as Monterey Bay.
- Conservationists applauded the changes, saying that they will save animals’ lives.
- The Pacific Coast Federation of Fishermen’s Associations was also involved in hammering out the settlement, and its representative said that the new rules, while “challenging,” would help the industry move toward a “resilient, prosperous, and protective fishery.”
New research teases apart complex effects of naval sonar on whales
- A pair of recent studies shows the unique responses of different whales to sonar, typically used by navies to detect submarines.
- Sonar sounds have been linked to hearing loss, deadly mass strandings and interference with whales’ communication with each other.
- One of the studies found that the distance the whales were from sonar sounds didn’t matter — they generally fled whether they were close to or far from it.
- Another study showed that sonar affected the feeding patterns of deep-diving blue whales, but not those that were feasting on krill at the surface.
Latam Eco Review: Pumas hate disco and Ecuador’s newly described glass frog
Ecuador’s most recently described glass frogs, a model plan for coastal management in Colombia, and using lights to scare away pumas in Chile were among the top recent stories from our Spanish-language service, Mongabay Latam. Colombia: Integrated coastal management protects local species and culture A fisheries zoning plan is protecting both local species and artisanal fishing […]
What underwater sounds can tell us about Indian Ocean humpback dolphins
- On today’s episode, we speak with marine biologist Isha Bopardikar, an independent researcher who is using bioacoustics to study humpback dolphins off the west coast of India.
- Last month, Mongabay’s India bureau published an article with the headline “What underwater sounds tell us about marine life.” As Mongabay contributor Sejal Mehta notes in the piece, the world beneath the ocean’s surface is a noisy place, with animals sounding off for a number of purposes. Now, of course, humanity is interjecting more and more frequently, intruding on the underwater soundscape.
- As Isha Bopardikar tells Mehta in the Mongabay India piece, in order to understand how marine animals use the underwater space and how human activities affect their behavior, we need hard data. That’s where her current work off the west coast of India comes in. In this Fields Notes segment, Bopardikar plays for us some of her dolphin recordings and explains how they are informing her research.
Tear down the dams: New coalition strives to enshrine rights of orcas
- A new coalition of scientists, indigenous peoples, community groups and lawyers is pushing for legal recognition of the rights of an endangered orca population living in the Salish Sea.
- The population, known as the Southern Resident Killer Whales, numbers just 75 individuals, down from 98 in 1995.
- The orcas are imperiled by noise and chemical pollution, the impending construction of Canada’s Trans-Mountain pipeline, and, most of all, severe salmon shortages caused by the damming of the rivers that feed into the sea.
Possible vaquita death accompanies announcement that only 10 are left
- The environmental organization Sea Shepherd said it found a dead vaquita in a gillnet on March 12.
- One day later, scientists from the group CIRVA announced that around 10 — as many as 22 or as few as six — vaquitas survive in the Gulf of California.
- Despite a ban on gillnets used catch totoaba, a fish prized for its swim bladders used in traditional Chinese medicine, vaquita numbers have continued to decline.
Wildlife conservation strategies must take animals’ social lives into account: Researchers
- In a paper published in Science last month, an international team of researchers argues that the growing body of evidence on the importance of social learning and animal cultures must be taken more fully into account in order to improve wildlife conservation efforts.
- “Animal culture” consists of information and behaviors shared amongst members of a wildlife community, such as a flock of migratory birds, a herd of elephants, or a pod of whales. For whooping cranes to retain knowledge of migration routes across generations, for instance, this knowledge must be passed between members of the flock through what scientists call “social learning.”
- Despite the mounting evidence of the far-reaching implications of social learning for the preservation of wildlife, however, international policy forums that devise large-scale conservation strategies “have so far not engaged substantially with the challenges and opportunities presented by this new scientific perspective,” the researchers note.
Blue whales remember best times and places to find prey
- A new study demonstrates that blue whales in the northern Pacific Ocean use their memories, instead of cues in the environment, to guide them to the best feeding spots.
- The researchers used 10 years of data to discern the movements of 60 blue whales.
- They compared the whales’ locations with spots with high concentrations of prey over the same period.
- The whales’ reliance on memory could make them vulnerable to changes in the ocean brought about by climate change.
Plastics found in dolphins, seals, and whales in UK waters
- In a paper published in the journal Scientific Reports last month, a research team from the UK’s University of Exeter and Plymouth Marine Laboratory detailed their findings after studying the digestive tracts of 50 individuals from 10 species of dolphins, seals, and whales that had been stranded on the coast of Britain.
- “Microplastics were ubiquitous with particles detected in every animal examined,” the authors of the study write.
- Just 5.5 microplastic particles were found in each animal, on average, which suggests that the particles might be simply passing through the marine mammals’ bodies, the researchers said. But the animals’ stomachs were found to contain more microplastics than their intestines, pointing to “a potential site of temporary retention,” they added.
Good news from Mexico monarch reserve despite looming deforestation, mine threat
- On today’s episode, we talk with Mongabay contributor Martha Pskowski, who recently traveled to central Mexico to report on threats to monarch butterflies in their overwintering grounds.
- Tourists typically arrive in droves to see the butterflies at the reserves set up in their overwintering grounds, and right now is a particularly good time to see the butterflies, as Mexico’s national commissioner for protected natural areas has announced that, after years of declines, the number of monarchs spending their winter in Mexico is up 144 percent from last year.
- As Pskowski found on her recent reporting trip to two different monarch butterfly reserves in the Mexican states of Michoacán and the State of Mexico, the annual arrival of the monarchs is a major component of the local economy, but the butterflies still face a variety of threats to their survival once they reach their overwintering grounds.
Marine mammal and sea turtle populations benefitting from Endangered Species Act listing
- New research published in the journal PLoS ONE this month finds that the US Endangered Species Act (ESA) is effectively aiding in the recovery of beleaguered populations of marine mammals and sea turtles.
- Marine mammals and sea turtles comprise 62 of the 163 marine species that are currently afforded ESA protections. Researchers collected annual abundance estimates for populations of all 62 of those marine mammal and sea turtle species in order to analyze population trends and the magnitude of observed changes in population numbers.
- The research team hypothesized that populations that have been listed under the ESA for longer periods of time would be more likely to be recovering than those species listed recently, regardless of whether they were listed as “threatened” or the more severe “endangered,” and that’s exactly what they found.
After a year of no babies, 3 right whale calves spotted off U.S. coast
- After a year of no reported births, whale surveying teams have observed three North Atlantic right whale calves so far during the 2018-2019 calving season, off the coast of Florida, U.S.
- Researchers photographed the first calf in late December last year, followed by a second calf on Jan. 13 and a third baby on Jan. 17.
- The North Atlantic right whale is one of the most endangered species of whales in the world, with their numbers dropping due to a combination of human-caused factors like collisions with ships and entanglement in fishing gear, as well as a declining birth rate.
Rhett Butler on how sound can save forests and top rainforest storylines to watch in 2019
- On today’s episode, we welcome Mongabay founder and CEO Rhett Butler to discuss the biggest rainforest news stories of 2018 and what storylines to watch in 2019. He also discusses a new peer-reviewed paper he co-authored that looks at how bioacoustics can help us monitor forests and the wildlife that call forests home.
- This year marks the 20th anniversary since Rhett Butler founded Mongabay. Subscribers to our new Insider Content Program already know the story of how he founded Mongabay.com two decades ago in his pajamas. At first, Mongabay was a labor of love that Rhett pursued in his spare time, after coming home from his day job.
- Mongabay has come a long way since then, with more than 350 contributors covering 50 countries and bureaus now open in India, Indonesia, and Latin America. Overseeing this global environmental news empire provides Rhett with a wealth of insight into the science and trends that are shaping conservation.
Japan leaving IWC, to resume commercial whaling
- The government of Japan confirmed today that it is withdrawing from the International Whaling Commission (IWC) and will resume commercial whaling operations in the North Pacific.
- The IWC, an inter-governmental organization founded in 1946 focused on whale conservation and management of the whaling industry, adopted a moratorium on hunting whales in 1982.
- The moratorium allows for IWC member nations to issue whaling permits for scientific research purposes. Japan has openly flouted the moratorium by issuing such permits and selling the harvested whale meat ever since the moratorium took effect in 1986.
U.S. whale entanglement figures steady in 2017
- The National Oceanic and Atmospheric Administration (NOAA) recorded 76 whale entanglements in U.S. waters in 2017.
- Floating fishing gear and other trash in the sea can impede a whale’s ability to feed and swim.
- Humpback were most often seen entangled; historically, the species usually accounts for about two-thirds of reports in a given year.
- Despite North Atlantic right whales only having been involved in two known entanglements in 2017, scientists say that any run-in with gear or trash threatens the recovery of the species, which now numbers around 450 animals.
Latam Eco Review: Jaguar protection plan signed by 14 Latin countries
A 14-country jaguar conservation plan, efforts to protect the last 7 female southern right whales in Peru and Chile, and unexpected biodiversity discovered along Chile’s north coast were among the top stories last week by our Spanish-language service, Mongabay Latam. Jaguar protection plan signed by 14 Latin countries Fourteen countries launched a plan to secure […]
Latam Eco Review: Whale attacks, palm oil woes, and hope for vaquitas
Peruvian palm oil, orca attacks on humpback whales, and mining in an Amazon national park are among the recent top stories from Mongabay Latam, our Spanish-language service. Orcas attack young humpbacks migrating north For 30 years, Juan Capella and five other researchers analyzed thousands of photos of humpback whales (Megaptera novaeangliae) off Panama, Colombia, Ecuador, […]
Trump Admin moves closer to authorizing oil and gas exploration off the Atlantic coast
- The Trump Administration announced today that it will issue five Incidental Harassment Authorizations (IHAs) for airgun blasting off the Atlantic coast. Seismic airgun blasting is used to search for oil and gas deposits deep beneath the floor of the ocean.
- Seismic surveying involves ships towing airgun arrays that continually blast intense bursts of compressed air into the water every 10 to 12 seconds as a means of determining what resources might lie beneath the ocean floor. These seismic airguns are so loud that the noise can travel as many as 2,500 miles underwater.
- Environmentalists were quick to decry the Administration’s decision to issue the IHAs on the grounds that marine mammals will face severe threats as a result of seismic testing in the Atlantic Ocean.
Whale stress levels influenced by human activity, earwax study suggests
- Using earwax collected from baleen (filter-feeding) whales in the Atlantic and Pacific oceans, scientists have been able to map the animals’ stress levels in relation to human activities over 146 years.
- Between 1870 and 2016, the whales’ stress levels closely corresponded to activities such as industrial whaling, naval operations during World War II, and rising sea-surface temperature, the study found.
- The effects on the whales of climate change, increased fishing and krill harvests, and sea ice decline need to be studied further, the researchers say.
Human activities are impeding population growth of North Atlantic right whales
- New research finds that deaths caused by human activities are not just impacting individual North Atlantic right whales and their immediate family units, but actually impeding population growth and recovery of the species, which has been declining since 2010.
- Peter Corkeron, head of a whale research initiative at NOAA’s National Marine Fisheries Service, led an international team that studied the western North Atlantic population and three populations of southern right whales, in order to determine whether or not the slow growth rate of North Atlantic right whales is attributable to humans.
- More than 80 percent of North Atlantic right whales have been entangled in fishing gear at least once in their lives, and 59 percent have been entangled two or more times, the researchers found. The increased energy demands imposed on entangled whales can reduce the likelihood that a female will successfully give birth.
Pod-cast: New app streams whale songs for web users in real time
- Researchers have developed a web application to enable citizen scientists to listen for the sounds of a population of killer whales off North America’s northeast Pacific coast in real time.
- A network of underwater microphones will stream sounds from under the sea to citizen scientists, who can then report any unusual noises and help decode orca language.
- The researchers have found that human listeners can readily detect unusual sounds amid a stream of underwater noise, and their participation can complement machine-learning algorithms being developed.
Tech prize finalists promote collaboration to fight extinction
- Conservation X Labs recently announced 20 finalists for the Con X Tech Prize. As finalists, each project receives $3,500 seed money to develop ideas that may be early stage or broad in scope.
- Among the finalists, the Wild N.O.S.E technology will use olfactory data to detect animals or animal parts and help stem trafficking, and the Right Whale Auto-Detect project listens for and identifies whale calls and then warns ships of whales in the area.
- These projects express Con X Tech values, such as collaboration, working across disciplines and thinking big enough to deliver transformative conservation solutions with “exponential impact.” One finalist will be selected in November 2018 to receive the $20,000 grand prize.
Whales not enough sustenance for polar bears in fast-changing climate
- Scientists believe that whale carcasses may have helped polar bears survive past upswings in temperatures that melted the sea ice from which they usually hunt seals.
- As the current changing climate threatens to make the Arctic ice-free during the summer, this strategy may help some populations of polar bears to survive.
- But according to new study, whale carcasses won’t provide enough food for most bear populations because there are fewer whales than there once were, and human settlements, industry and shipping could affect the bears’ access to any carcasses that do wash ashore.
Young right whale dies, likely from entanglement in fishing gear
- A young North Atlantic right whale died off the coast of Massachusetts in August, probably as the result of entanglement in fishing gear.
- After centuries of hunting, the right whale population in the North Atlantic has failed to recover, in large part because they’re prone to getting entangled in fishing gear.
- Only about 450 of the animals remain, after 17 died between late 2016 and 2017, and no new calves were observed last winter.
Largely banned industrial chemicals could wipe out killer whales, study warns
- New research shows that despite countries phasing out polychlorinated biphenyls (PCBs) more than 40 years ago, the chemicals remain a major threat to killer whales around the world, and could wipe out most populations in just 30 to 50 years.
- Killer whale populations that occur in least PCB-polluted parts of the ocean, such as those around the poles, Norway and Iceland, still have a large number of individuals and are at low risk.
- However, populations occurring in waters that have had historically high concentrations of PCBs, such as those around Japan, Brazil, the northeast Pacific, the Strait of Gibraltar, and the U.K., are all tending toward complete collapse in the next few decades, according to the study’s modeled scenarios.
Latam Eco Review: Shark ceviche, bat-friendly tequila, and protein-rich worms
Recent top stories from our Spanish-language service, Mongabay-Latam, revealed Peruvians’ hidden shark diet, new species in Colombia’s Chiribiquete National Park, dire predictions from Mexico’s “Batman,” and more. Peruvians are eating shark and don’t know it Three out of four Peruvians recently surveyed were found to have eaten shark meat without knowing it. The problem stems […]
Taking it slow can help reduce impacts of Arctic shipping on whales (commentary)
- Thanks to climate change, traveling through the Northwest Passage is quickly becoming an exotic option for cruise ship passengers — and an enticing shortcut for cargo ships.
- But an increasingly ice-free Arctic means more than just a chance for a new sightseeing adventure: Significantly increased ship traffic is altering the submarine calm of one of the quietest places on Earth. That could have serious implications for marine mammals and fish that rely on sound for group cohesion, socializing, finding mates, navigating, and detecting threats.
- As we grow sensitive to plastics and other toxins that plague ocean species, we must remember that while noise is the one form of pollution that we cannot see, we can work together to turn down the volume.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.
Global marine wilderness has dwindled to 13 percent, new map reveals
- New research examining the effects of 19 human stressors on the marine environment shows that only 13 percent of oceans can still be considered wilderness.
- Of the remaining wilderness, much of which is located in the high seas and at the poles, less than 5 percent falls under protection, and climate change and advances in technology could threaten it.
- The authors of the study call for international cooperation to protect the ocean’s wilderness areas, including a “Paris Agreement for the Ocean,” which they hope will be signed in 2020.
Red flags abound as a warming Arctic opens up to shipping
- Ship traffic through the Arctic is expected to increase dramatically as global warming renders a growing proportion of the region ice-free.
- Conservationists warn that the higher number of vessels raises the risks of pollution, oil spills, and disturbances to marine mammals from propeller noise.
- They propose a slate of regulatory measures that could help mitigate the anticipated impacts, which could then be extended to other vulnerable maritime regions.
How to use drones without stressing wildlife
- On today’s episode, we discuss the increasing use of drones by wildlife lovers, researchers, and businesses, how that might be stressing animals out, and how drone hobbyists can actually make a meaningful contribution to science while avoiding the harassment of wildlife.
- Our guest is Alicia Amerson, a marine biologist, drone pilot, and science communicator. She tells us why it’s critical that we have best practices for drones in place before we allow companies like Amazon and Uber to deploy fleets of drones in our skies.
- “I want to hit the panic button and create policy” before we have drone-based delivery services by companies like Amazon and Uber “and look and collect data to make sure that we understand what populations are using the skies before we release all of these drones into our world. And so you have to create best practices and policies before all this really gets out of control.”
Ice-free passage for ships through the Arctic could cause problems for marine mammals
- A new study suggests that increased ship traffic in the Arctic, as ice there melts due to climate change, could disturb marine mammal species.
- In their assessment of 80 subpopulations living along the Northwest Passage and Russia’s Northern Sea Route, 42 are likely to be affected by a greater number of commercial ships, researchers found.
- The team suggests that mitigation measures, such as those employed in other parts of the world to protect North Atlantic right whales, could be effective.
Sylvia Earle on why we must act now to save the oceans
- On today’s episode, renowned marine biologist Sylvia Earle joins us for an in-depth conversation about marine conservation.
- Legendary oceanographer, marine biologist, and environmentalist Sylvia Earle, sometimes known as "Her Deepness" or "The Sturgeon General," is a National Geographic Explorer-in-Residence and former chief scientist at the US National Oceanic and Atmospheric Administration (NOAA). A documentary film about her work called Mission Blue won a 2015 News & Documentary Emmy.
- She joins us today to discuss how effective marine protected areas are at conserving the oceans and their inhabitants, her Hope Spots program that is identifying some of the most valuable marine environments on the planet, and the latest advances in marine conservation that she is most hopeful about.
Humpback whales near Antarctica making a comeback, study finds
- Humpback whales living around the Western Antarctic Peninsula seem to be recovering rapidly, indicated by females showing high pregnancy rates, a new study has found.
- Researchers also found a high proportion of females that are both lactating and pregnant, which is a sign that the humpback whale population there is growing.
- So far, changing climate in the Western Antarctic Peninsula has been beneficial for the humpbacks because of more ice-free days and more access to food. But long-term trends of climate change may be more problematic, the researchers write.
Impacts of agriculture on Brazil’s Cerrado region
- On today’s episode: the impacts of agriculture on Brazil’s Cerrado region. Incredibly biodiverse, the region supports more than 10,000 plant species, 900 birds, and 300 mammals. But it has long been overlooked by scientists and environmentalists alike, and as protecting the Amazon has become more of a priority, much agricultural production in Brazil has moved from the rainforest to the vast Cerrado savannah.
- In February, Mongabay sent journalists Alicia Prager and Flávia Milhorance to the Cerrado region of central Brazil to report on the impacts of this rapid expansion of agribusiness on the region’s environment and people.
- Prager and Milhorance filed a series of six reports and they're here to tell us what they found.
Audio: Bowhead whales in the Arctic sing hundreds of complex songs
- Scientists have recorded 184 elaborate, very different bowhead whale songs in a bowhead subpopulation living east of Greenland. This makes it the largest set of bowhead whale song recordings ever.
- The bowhead’s vocal repertoire is rivaled only by a few species of songbirds, researchers say.
- But why these whales have so many different song types and why they change their songs each year is still a mystery.
NOAA publishes global list of fisheries and their risks to marine mammals
- The list, published in draft form in late 2017 as part of requirements laid out by the Marine Mammal Protection Act, includes nearly 4,000 fisheries across some 135 countries.
- NOAA says the list represents ‘a strong step forward’ in developing sustainable fisheries.
- These fisheries have until 2022 to demonstrate that the methods they use to catch fish and other marine animals either pose little risk to marine mammals or employ comparable methods to similar operations in the United States.
Brazil creates four massive marine protected areas
- The four newly designated marine protected areas (MPAs) will cover an area of more than 920,000 square kilometers (355,200 square miles) in the Atlantic Ocean.
- Two of the MPAs will cover waters around the archipelago of Trindade, Martin Vaz and Mount Columbia, located more than 1,000 kilometers (620 miles) east of the Brazilian mainland.
- The remaining two MPAs will be located around the São Pedro and São Paulo archipelagos, some 900 kilometers (560 miles) off the northeast coast.
- However, some marine biologists worry that these large, remote MPAs may do little to safeguard biodiversity.
‘Ropeless’ consortium aims to end entanglements of declining North Atlantic right whales
- ‘Fishermen, engineers, manufacturers, scientists and managers’ have come together to develop ropeless fishing gear to keep North Atlantic right whales from getting entangled.
- Only 451 right whales are left, and it’s likely that fewer than 100 are breeding females.
- Research teams have recorded no new calves this breeding season, which ended this month.
- Scientists warn that the North Atlantic right whale could go extinct if the trend in their numbers doesn’t change.
Microplastic pollution in world’s oceans poses major threat to filter-feeding megafauna
- A study published in the journal Trends in Ecology & Evolution last month looks at how filter-feeding marine animals like baleen whales, manta rays, and whale sharks are impacted by microplastic pollution in the world’s oceans.
- Filter-feeding megafauna must swallow hundreds to thousands of cubic meters of water every day in order to catch enough plankton to keep themselves nourished. That means that these species are probably ingesting microplastics both directly from polluted water and indirectly through the consumption of contaminated plankton prey.
- Microplastic particles can block nutrient absorption and damage the digestive tracts of the filter-feeding marine life that ingest them, while toxins and persistent organic pollutants (POPs) found in plastic can accumulate in the bodies of marine wildlife over time, changing biological processes such as growth and reproduction and even leading to decreased fertility.
Whale of a tale: Protecting Panama’s humpbacks from ship collisions
- The key to alleviating whale strikes in the Panama Canal ended up being inspired by a solution used on land — and led to a years-long struggle for a Panama Canal pilot and a whale biologist to help reduce whale strikes in the Gulf of Panama, one of the world’s busiest shipping lanes.
- Similar to how roads are now sometimes built to curve around the natural habitats of land creatures, Traffic Separation Schemes (TSS) create shipping lanes that restrict marine traffic to certain areas.
- But in order to get all shipping to abide by this system, countries need the approval of the International Maritime Organization (IMO), a UN body that regulates shipping safety and navigation around the world.
African Parks backs marine reserve brimming with wildlife in Mozambique
- The conservation NGO African Parks signed an agreement to manage Bazaruto Archipelago National Park in Mozambique.
- Leaders established the park in 1971, but recent illegal fishing and unregulated tourism has threatened the ecosystem and its economic value, African Parks said.
- The park is home to 2,000 species of fish and hundreds of species of birds, reptiles and mammals, including some of the last dugongs in the western Indian Ocean.
Amazon tribe’s traditional medicine encyclopedia gets an update, and conservation effectiveness in Madagascar examined
- On today’s episode, we’ll get an update on an ambitious effort to document traditional indigenous healing and medicinal practices in the Amazon and speak with the reporter behind Mongabay’s popular new series on conservation efforts in Madagascar.
- Our first guest on today’s episode of the Mongabay Newscast is Christopher Herndon, who, as co-founder and president of the group Acaté Amazon Conservation, has supported the Matsés people in planting healing gardens, which are basically living pharmacies as well as classrooms, and to document their traditional healing and plant knowledge in an encyclopedia.
- Our second guest is Mongabay contributor Rowan Moore Gerety, the writer behind our recent series on the effectiveness of conservation interventions in Madagascar.
Entanglements hamper reproduction as right whale population slides
- Just 451 North Atlantic right whales remain, down from 458 in 2016 and 483 in 2010.
- Entanglements in fishing gear and ship strikes remain the two most important threats to right whale survival.
- A study published in November in the journal Ecology and Evolution finds that fewer females are surviving than males and the interval between calving is growing longer.
4 sperm whales dead after mass stranding in Sumatra
- A pod of 10 sperm whales beached earlier this week in shallow waters in western Indonesia.
- Despite attempts by authorities and residents to push the animals back out into deeper water, four of the whales died after being stranded overnight.
- Experts are looking into what caused the whales to swim so close to shore.
‘Record’ number of migratory species protected at October wildlife summit
- The Convention on Migratory Species adopted 34 proposals to protect species threatened with extinction.
- Attendees adopted proposals to bolster protections for chimpanzees, giraffes, leopards, lions and whale sharks.
- India will host the next such meeting in 2020.
‘Ships, sonar and surveys’: Film explores impacts of a noisy ocean
- Sonar, air gun charges for oil and gas exploration, and ship traffic in the ocean can interfere with marine mammal communication, cause physiological problems and drive animals to strand on beaches.
- A new film, “Sonic Sea,” traces the risks of an increasingly noisy ocean to whales, dolphins and porpoises.
- The film is a finalist for the Best Science in Nature prize at the 2017 Jackson Hole Wildlife Film Festival in Jackson, Wyoming.
- The winners will be announced Sept. 28.
Move to open U.S. Atlantic coast to oil drilling meets increased opposition
- In April, Trump issued an executive order aimed at implementing his so-called “America-First Offshore Energy Strategy,” which called for a review of the 2017-2022 Five Year Outer Continental Shelf Oil and Gas Leasing Program finalized under the Obama Administration and proposed that all U.S. waters be considered for offshore drilling.
- The executive order also instructed federal agencies to “streamline” the permitting process for “seismic research and data collection” and “expedite all stages of consideration” of Incidental Harassment Authorizations required under the Outer Continental Shelf Lands Act and the Marine Mammal Protection Act.
- A species of particular concern is the North Atlantic right whale, which is listed as critically endangered under the US Endangered Species Act. There are only about 500 of the whales left, and their only known calving ground is off the coast of the southeast US, including the area where seismic surveying has been proposed.
Surprisingly, Indonesia’s most famous dive site is also a playground for whales and dolphins (commentary)
- Raja Ampat — an island chain in Indonesia’s West Papua province — is world renowned for its beautiful and unique marine biodiversity. But its marine mammals have not received as much attention.
- Half of the 31 whale and dolphin species found in all of Indonesia — 16 different types — have been regularly observed there.
- However, a designated long-term study of the behavior of whales and dolphins there has yet to be conducted. We don’t know much about them; more to the point, we don’t know how to effectively protect them.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.
The fight to save Indonesia’s Leuser Ecosystem
- One of the richest, most biodiverse tropical forests on the planet, Leuser is currently being targeted for expansion of oil palm plantations by a number of companies.
- Tillack explains just what makes Leuser so unique and valuable, details some of her organization’s investigations into the ongoing clearance of Leuser in violation of Indonesia’s moratorium on deforestation for new oil palm plantations, and how consumers like you and me can help decide the fate of the region.
- We also welcome to the show research ecologist Marconi Campos Cerqueira for our latest Field Notes segment. Cerqueira has recently completed a study that used bioacoustic monitoring to examine bird ranges in the mountains of Puerto Rico, and he’ll share some of his recordings with us on today’s show.
Whale entanglements skyrocket off the U.S. West Coast
- Whale entanglements are rising, leading to concerns that current regulations are inadequate.
- The most commonly entangled whale is the humpback.
- California’s Dungeness crab fishery is responsible for a third of last year’s whale entanglements.
Gabon pledges ‘massive’ protected network for oceans
- The network of marine protected areas covers some 53,000 square kilometers (20,463 square miles) of ocean, an area larger than Costa Rica.
- The marine parks and reserves could also draw tourists eager to catch a glimpse of the humpback whales (Megaptera novaeangliae), olive ridley sea turtles (Lepidochelys olivacea) and leatherback sea turtles (Dermochelys coriacea) that all shuttle through Gabonese waters.
- Government officials are in the process of overhauling how they manage fisheries, and they hope the move to protect Gabon’s territorial waters will improve the country’s food security and give its citizens a better chance to earn a living from fishing.
Microalgae genes help them adapt to harsh oceans, other species less lucky
- Researchers have long wondered how microalgae manage to survive in polar seas, where conditions are extreme and change rapidly.
- New research looking at the DNA of a diatom finds that the species likely evolved with the ability to quickly change which genes are expressed making it ready for anything.
- This research hints that diatoms may be able to adapt to climate change – but that doesn’t mean other vital species, such as krill, have the capacity to do the same.
Paul Simon on his new tour in support of E.O. Wilson’s Half-Earth initiative
- The 12-time Grammy-winning singer-songwriter recently announced on Mongabay.com that he is embarking on a 17-date US concert tour, with all proceeds benefitting Half-Earth, an initiative of the E.O. Wilson Biodiversity Foundation.
- Mongabay contributor Justin Catanoso interviewed Paul Simon about his long-time friendship with E.O. Wilson and why Dr. Wilson’s Half-Earth idea inspired him to get involved in this environmental cause.
- We also feature another Field Notes segment, this time with Zuzana Burivalova, a conservation scientist at Princeton University who has recorded the soundscapes of over 100 sites in the Indonesian part of Borneo.
Rare beaked whale filmed underwater for the first time
- True’s beaked whale is difficult to spot at sea, and remains a poorly studied species.
- By analyzing stranding data and live sightings of the whale, researchers confirm that the Azores and Canary Islands may actually be a hotspot for studying the natural behavior of the species.
- For the data-scarce whale species, live sightings and video recordings are highly valuable because they add to information that helps identify a species accurately.
- This in turn can help scientists monitor the status of their populations and protect them.
Newscast #8: Top new species discoveries of 2016, and how fig trees can save rainforests
- The new species we discover every year prove that we still aren’t even aware of every creature with whom we share planet Earth, so there’s literally more to protect than we can possibly know.
- We also speak with author Mike Shanahan, whose new book 'Gods, Wasps, and Stranglers: The secret history and redemptive future of fig trees' looks at the tropical species’ biology and key ecological role, as well as its deep cultural (and spiritual) place in human history.
- Thanks to everyone who made the launch of the Mongabay Newscast in 2016 such a success!
Distinctive sperm whale cultures reveal dramatic population shifts in the Galápagos
- Researchers studied distinctive communication clicks among sperm whales to track several cultural clans in the Pacific Ocean.
- Two clans dominated the waters near the Galápagos decades ago, but whales from two different clans have since moved in from across the Pacific basin.
- Managing sperm whales may require tracking their populations culturally, rather than geographically.
Humpback whales learn habitat loyalty from their mothers, Alaskan study shows
- Marine biologists studied relationships among humpback whales in Glacier Bay and Icy Strait, Alaska, over a 30-year period.
- The whales’ loyalty to their feeding grounds is passed down from mothers to calves and persists through the generations.
- North Pacific humpback whales are making a comeback, and the new study shows how critical it is to protect their key habitats.
A week of grim tidings for critically endangered right whales
- The population of critically endangered North Atlantic right whales numbers just 500.
- The whales’ population has grown in recent decades, but its growth rate appears to be declining due to a combination of human-caused deaths and a drop in calving, researchers say.
- The recent spate of deaths and entanglements, combined with the flagging population, an unexplained shift in habitat, and the poor health of many whales spotted this summer has researchers concerned for the future of the species.
Whalesong, interrupted
- Baleen whales broadcast complex songs over long distances underwater, but maritime noise pollution from ships and other sources is squeezing their ability to communicate.
- With regulatory and technical solutions to ocean noise slow to spread, some researchers are optimistic that whales themselves will be able to change their vocalizations to overcome the din.
- Meanwhile, the U.S. National Oceanic and Atmospheric Administration last week released a strategy to study and mitigate rising noise levels and their effect on marine life.
NOAA establishes final rule on marine mammal bycatch for seafood imports
- The U.S. National Oceanic and Atmospheric Administration (NOAA) Fisheries issued a final rule earlier this month to implement import provisions of the Marine Mammal Protection Act (MMPA), which was enacted in 1972.
- The rule aims to prohibit seafood imports from countries where fisheries kill more marine mammals such as whales and dolphins than U.S. standards allow.
- Bycatch is the greatest direct cause of marine mammal injury and death in the United States and around the world, according to the U.S. Marine Mammal Commission.
Humpback whales rescue seals and other animals from killer whales
- After reviewing over 100 interactions between humpback whales and killer whales, researchers have found that not only do humpbacks aggressively protect their own calves from killer whales, they also tend to rush to the aid of other distraught species like seals.
- A humpback might be able to fight a killer whale because of its gigantic size and massive flippers, researchers say.
- One possible reason for the humpbacks’ seemingly selfless act could be to increase the chance of protecting their own calves from killer whales. Sometimes this ends up protecting other species.
The ‘raven’ whale: scientists uncover new beaked whale
- In 2014, a teacher stumbled upon a strange-looking whale that had washed up on a beach in Alaska.
- The new whale looked similar to Baird’s beaked whale, but was darker and had a larger dorsal fin and a unique skull.
- Recently released genetic evidence shows the whale is indeed a new species, as distinct from Baird’s beaked whale as it is from its closest Antarctic relative.
- Beaked whales are the world’s deepest-diving mammals – surpassing even the sperm whale. Many species remain little studied.
5 Tech Projects That Are Protecting Sharks
- Annually, approximately 100 million sharks are killed by commercial fisheries.

- In celebration and support of Shark Week 2016, we are excited to highlight five different organizations and technologies that are being used to protect shark species.
Top 10 stories you should be aware of this World Oceans Day, according to Carl Safina
- Safina’s latest book, Beyond Words: What Animals Think and Feel, came out in 2015, and is due for a paperback release on July 12 via Picador.
- “It’s about the thought and emotional range of non-human animals, but including humans,” Safina told Mongabay.
- Safina’s list of stand-out stories includes several oceans and marine life stories, a couple that just show how similar to humans animals can really be, and a few that will interest anyone concerned with the plight of the natural world.
Japan kills 333 whales, including 200 pregnant females
- Last week, Japan’s whaling fleet returned with a harvest of 333 Minke whales, including 200 pregnant females.
- This latest hunt seems to be in apparent violation of the International Court of Justice’s (ICJ) 2014 ruling ordering Japan to halt all whaling.
- Japan maintains that the killing of whales, including juveniles and pregnant females, is necessary to determine whether the Anatarctic whale population is healthy for future commercial whaling.
- The country plans to kill about 4,000 whales over the next 12 years.
Here are the top happy environmental stories of 2015
- The world is finally getting serious about tackling climate change — and that means protecting forests, too.
- Scientists finally documented a “mystery whale” in the wild, as well as a number of other newly discovered species.
- China and the United States announced a joint partnership to end the illegal trade in elephant ivory.
Crab fishermen train as first responders for entangled whales
- Whales regularly get caught by fishing gear or marine debris, which can wound or kill them. So far this year, 46 entangled whales have been reported off California shores, four times the annual average for the entire continental west coast between 2000 and 2012.
- On the U.S. west coast, crab gear was involved in nearly half of the whale entanglements reported during the past decade.
- This October, around 100 San Francisco-area crab fishermen learned how to identify, report, and monitor whales trapped by fishing gear. The training is part of a larger effort to better understand how and where whales become entangled and what can be done to minimize the harm to these animals.
Mystery whale known only from specimens found living in the wild
- A handful of unusual whale specimens were recognized as a separate species called Omura’s whale (Balaenoptera omurai) in 2003.
- Until now there have only been a few unconfirmed sightings of living Omura’s whales.
- A new study describes 44 observations of the whales off northwestern Madagascar, providing the first confirmed description of living Omura’s whales, including photos, videos, and audio recordings.
Photos: Drone captures stunning images of killer whales
- A specialized drone has captured thousands of striking high-resolution images of killer whale populations in the United States.

Hunted orcas spotlight Caribbean whaling
- Whalers from the Caribbean country of St. Vincent and the Grenadines (SVG) routinely hunt small cetaceans, such as pilot whales, orcas, and dolphins.
- Preliminary results suggest the meat of small cetaceans hunted in SVG may be contaminated with mercury.
- SVG is the only Caribbean country with an exemption from the International Whaling Commission’s moratorium on commercial hunting of large whale species, which allows the country to hunt a small number of humpback whales each year.
Three dead in three weeks: a blow for endangered right whales
Between June 24 and July 13, no fewer than three carcasses of endangered North Atlantic right whales were found floating in Canadian waters in the Gulf of St. Lawrence. With just around 500 individuals alive, the untimely death of any North Atlantic right whale (Eubalaena glacialis) is cause for concern, scientists say. The species has […]

Japan changes its mind about Antarctic whaling ban, plans to continue hunts in 2015
Conservation groups were jubilant in response to last month’s ruling by the International Court of Justice (ICJ) banning Japan’s long-standing “research” whaling practices in the Antarctic. However, the celebrations proved short-lived after news last week that Japan has rescinded its agreement to abide by the ruling and stop whaling altogether, opting instead to redesign its […]
Court partially stops Japan’s ‘scientific’ whaling, but Pacific harvests to continue
Japan has harvested thousands of whales in North Pacific and Antarctic waters since the implementation of a global ban on whaling, eliciting harsh criticism from the international community. Now, in a landmark decision, the International Court of Justice (ICJ) has ruled that Japan must cease its whaling activities in the Antarctic. The advent of factory […]
Scientists spy on whales from space

Beyond Bigfoot: the science of cryptozoology
- Anyone who doubts cryptozoology, which in Greek means the “study of hidden animals,” should remember the many lessons of the past 110 years:
- the mountain gorilla (discovered in 1902), the colossal squid (discovered in 1925, but a full specimen not caught until 1981), and the saola (discovered in 1992) to name a few.
- Every year, almost 20,000 new species are described by the world’s scientists, and a new book by Dr. Karl Shuker highlights some of the most incredible and notable new animals uncovered during the past century.
Featured video: scientists capture first footage of Shepherd’s beaked whale
Scientists have captured what is believed to be the world’s first footage of the cryptic Shepherd’s beaked whale (Tasmacetus shepherdi), one of a number of beaked whale species about which scientists know almost nothing.

Photos: satellite tracking of the unicorn of the sea
- A new program aims to track one of the ocean’s most enigmatic creatures: the narwhal (Monodon monoceros).
- Tagging nine narwhales in August, researchers plan to track the species in order to gain new insights about how the little-known toothed whale will withstand a rapidly melting Arctic due to climate change.
- “[This] is a chance to better understand these animals while their world changes around them. We know narwhals are often associated with sea ice, and we know the sea ice is shrinking.
- WWF is trying to understand how narwhals, as well as all other ice associated animals in the arctic can adapt to a changing environment,” says Peter Ewins with WWF-Canada.

The glass is half-full: conservation has made a difference
Focused conservation efforts, including reintroduction of captive individuals into the wild, have saved the golden lion tamarin from extinction. Photo by: Rhett A. Butler. Don’t despair: that’s the message of a new paper in Trends in Ecology and Evolution, which argues that decades of conservation actions at multiple scales have had a positive impact for […]
Decline in top predators and megafauna ‘humankind’s most pervasive influence on nature’
Lioness defends wildebeest kill in Tanzania. Photo by: Rhett A. Butler. Worldwide wolf populations have dropped around 99 percent from historic populations. Lion populations have fallen from 450,000 to 20,000 in 50 years. Three subspecies of tiger went extinct in the 20th Century. Overfishing and finning has cut some shark populations down by 90 percent […]
Animal picture of the day: humpback whale breaching
Humpback whale breaching in Alaska. Photo by Rhett Butler. The humpback whale (Megaptera novaeangliae) is a conservation success story. Decimated by centuries of whaling, most populations have risen since a moratorium was placed on commercial whaling in the 1966. Today, over 60,000 humpback whales migrate through the world’s oceans, though this is still considerably less […]
Rise in the number of whales hit by ships prompts Coast Guard to consider changes
A bumper crop of krill along the West Coast this past summer lured whales into the paths of cargo ships. With five collision deaths confirmed, and many more suspected, the US Coast Guard is investigating ways to mitigate future losses of these rare mammals. The first was a humpback whale with propeller gouges that washed […]
Kite-photography gives new perspective to whale migration
A new project sponsored by Nokia uses KAPing – kite aerial photography – to get an innovative look at whale behavior. The project will be taking place in Hawaii and will document the area’s annual humpback whale migration. KAPing uses kites to suspend cameras, providing a birds-eye view of a scene without need for a […]
Disappearance of arctic ice could create ‘grolar bears’, narlugas; trigger biodiversity loss
The melting of the Arctic Ocean may result in a loss of marine mammal biodiversity, reports a new study published in the journal Nature and conducted jointly by the National Oceanic and Atmospheric Association (NOAA), the University of Alaska, and the University of Massachusetts. The study is the first to project what might happen if […]
Island nation announces Ukraine-sized sanctuary for whales and dolphins
Dolphins, whales, and dugongs will be safe from hunting in the waters surrounding the Pacific nation of Palau. At the Convention on Biological Diversity (CBD) in Nagoya, Japan, Palau’s Minister of the Environment, Natural Resources and Tourism, Harry Fritz, announced the establishment of a marine mammal sanctuary covering over 230,000 square miles (600,000 square kilometers) […]
Flickr reveals longest whale migration
Communal photo sharing site, Flickr, has allowed researchers to discover the longest migration by a whale yet recorded. Ten years ago a female humpback whale swam from Brazil to Madagascar, covering around 6,090 miles (9,800 kilometers). The migration tops the previous record by 2,485 miles (4,000 kilometers). Not only is this a record for a […]
Oil disaster threatens Gulf of Mexico’s deep water titans
As I discovered in the course of researching my book, No Rain in the Amazon: How South America’s Climate Change Affects the Entire Planet (Palgrave, 2010), the oil industry has had a poor record when it comes to protecting aquatic sea life. Take for example the manatee, which has been put at risk from the […]
Conservation photography: on shooting and saving the world’s largest temperate rainforest, an interview with Amy Gulick
Most of the US’s large ecosystems are but shadows of their former selves. The old-growth deciduous forests that once covered nearly all of the east and mid-west continental US are gone, reduced to a few fragmented patches that are still being lost. The tall grassy plains that once stretched further than any eye could see […]
In the midst of marine collapse will we save our last ocean?
An interview with David Ainley. Imagine an ocean untouched by oil spills: a sea free of pollution, invasive species, dead zones, and over-exploitation; waters where marine animals exist in natural abundance and play ecological roles undimmed by mankind. Such a place may sound impossible in today’s largely depleted oceans, but it exists: only discovered in […]
Whaling talks break down: ban stays in place, yet whaling will continue
Update: The International Whaling Commission (IWC), which was supposed to decide a way forward for whales over the next decade has ended without an agreement. Talks broke down, according to participants, because countries opposed to whaling and those that continue hunting and killing whales despite a ban on commercial whaling—i.e. Japan, Norway, and Iceland—have been […]
To whale or not to whale?: nations, environmental groups do some soul-searching
There are two ways forward on whaling according to visions being put forward at the International Whaling Commission this week. One way is to uphold the 24-year-long ban on hunting and killing whales. While this road sends a strong pro-conservation message, it also means that Japan, Norway, and Iceland will continue whaling as they have […]
The penguin crisis: over 60 percent of the world’s penguins threatened with extinction
Everyone loves penguins. With their characteristic black-and-white ‘tuxedo’ markings, upright waddle, and childlike stature, penguins seem at once exotic and familiar: exotic because they live far from most human habitations, familiar because they appear in innumerable books and movies. From Mr. Popper’s Penguins to Happy Feet, and from March of the Penguins to And Tango […]
Will we ever know the full wildlife toll of the BP oil spill?
Will we ever know the full wildlife toll of the BP oil spill? The short answer: no. The gruesome photos that are making the media rounds over the last week of oiled birds, fish, and crustaceans are according to experts only a small symbol of the ecological catastrophe that is likely occurring both in shallow […]
Whale skeleton reveals species unknown to science
The importance of a whale to the oceanic ecosystem does not end with its life. After dying, a whale’s body sinks to the bottom of the ocean and becomes food for many species, some of whom specialize on feeding on these corpses. Using underwater cameras, researchers with the University of Gothenburg, Sweden have discovered nine […]
Slaughter of dolphins and whales begins in cove made famous by film
Japan Probe reports that the annual dolphin slaughter by fishermen in the Japanese town of Taiji has begun. The hunt was delayed by the presence of Japanese and foreign press in the cove during the first days when the hunt was supposed to begin. Japan Probe states that thirteen boats left the harbor at 5:30 […]
