Riverside families in the Amazon change meals as mercury poisons staple fish
- A database built by Mongabay Latam, based on the analysis of scientific studies that gathered more than 7,000 samples from humans and 5,900 from fish, identified the areas most affected by mercury contamination in the Madeira River, one of the main tributaries of the Amazon.
- Mongabay Latam investigated the impact of mercury contamination on the health of the most affected communities: Lake Puruzinho in the state of Amazonas, and the riverside community of Calama and the Karipuna Indigenous Territory, in Rondônia state.
- Studies show that mercury concentrations among residents of Lake Puruzinho are among the highest recorded in the Madeira River Basin and well above what the World Health Organization considers safe, prompting residents to change their eating habits.
- High levels of mercury in Amazonian communities are related to fish consumption, their main source of protein; the accumulation of mercury in humans can cause serious health damage, such as motor and neurological problems, researchers say.

New analysis maps mercury threat to 951 Amazon communities in three countries
For the first time, Mongabay Latam analyzed 39 scientific studies published between 1997 and 2024 that confirm that 249 Indigenous and riverside communities in Peru, Bolivia and Brazil have been exposed to mercury contamination. Nearly all of them exceed the limits considered safe by the World Health Organization. The stories reported by three journalistic teams […]
New-to-science Amazon frog stands out for its slow ‘lazy’ song
Scientists recently described a new species of a tiny brown frog found in the Amazonian floodplain forests of Ecuador and northwestern Brazil. It looks nearly identical to related species but its slow, widely spaced out call sets it apart, researchers note in a study. “I’ve had to get into arguments because people said the frog […]
Brazil’s Senate passes rare earth minerals regulation, paving the way for boosted exploration
RIO DE JANEIRO (AP) — Brazil’s Senate has approved a bill to regulate the exploration of critical minerals, including rare earths, marking a step toward exploiting its vast reserves. The bill approved Thursday now awaits President Lula’s signature. It establishes a legal framework and offers tax incentives for domestic processing. Brazil holds the world’s second-largest […]
Key tree species boost Amazon forest restoration, new study shows
- A study in Global Change Biology shows that just 15 to 25 tree species make up nearly half of the trees and carbon stocks in regrowing Amazon forests.
- While pioneer species grow quickly, experts warn that forests need a robust succession of stronger trees to avoid ecological decline over time.
- Understanding these forest dynamics may help Brazil meet its international pledge to restore 12 million hectares (30 million acres) of forest by 2030.

Planned Bolivia-Brazil highway threatens Chiquitania dry forest
- Bolivian President Rodrigo Paz signed an agreement to begin technical studies for a highway connecting the municipality of San Ignacio de Velasco in the Chiquitania region with the Brazilian state of Mato Grosso.
- Brazilian businesspeople looking to buy land in the Chiquitano forest for cattle ranching and soy farming are driving the project.
- Brazilian businessman Eraí Maggi, known as the “soy king,” is a central figure behind this agricultural expansion into Bolivia.
- Experts warn the road will accelerate deforestation in the Chiquitania, the largest tropical dry forest in the Americas, in a country that already ranks second globally in tropical forest loss.

Mexico-Brazil oil deal raises concern for ecosystems and energy transition
- This June, Pemex and Petrobras, the state fossil fuel companies of Mexico and Brazil respectively, announced a two-year partnership to jointly explore mature and deepwater oilfields in the Gulf of Mexico.
- Details of the exact arrangement have not been released, despite both companies being state-run and campaigners’ calls for greater transparency, but subsequent reports suggest that exploration could focus on the Bay of Campeche, near the Gulf’s largest marine protected area and several vulnerable reef habitats.
- Both companies have downplayed the significance of the deal as a preliminary step, but environmental campaigners said it risks tying both nations to decades of fossil fuel emissions and pollution.
- Supporters hope the partnership will help staunch a recent run of safety incidents at Mexican petrochemical sites.

Invaders storm Indigenous Amazon land, threatening isolated people
- About 200 people have invaded the Ituna/Itatá Indigenous Land in Brazil’s Pará state since August 13, breaking through Brazil’s Indigenous Affairs Agency (Funai) gates, removing signs and establishing camps.
- The invasion followed the creation of the Bacajaí Environmental Protection Area that completely overlaps with the federally protected Indigenous Land — creating legal confusion which authorities say has been exploited by individuals who wish to occupy the area.
- Federal authorities have warned of an imminent risk of confrontation and potentially genocide against Indigenous people living in voluntary isolation and have called for the urgent deployment of the National Force and Federal Police.
- On August 26, a federal court ordered the Union and Funai to send teams from the Public Security Force within 48 hours to contain the invasion but the deadline has passed and the teams have not yet arrived.

Tiago Karaí and Laudiceia Benites helped reclaim Guarani land. They died with their children in an accident last month.
- Guarani leaders Tiago Karaí and Kerexu Laudiceia Benites died with their two children and three other members of Tekoa Kalipety when a semitrailer struck their car on August 14. Tiago was 34; Laudiceia was 31.
- Tiago began as a teacher of Guarani language and culture before helping reclaim parts of the Tenondé Porã Indigenous Territory and organizing campaigns over land rights, railway impacts, and environmental protection.
- Laudiceia taught philosophy and history, studied traditional medicines, and helped maintain the family’s prayer house. Tiago’s sister Cleonice, who also died in the accident, was a ceremonial singer, midwife, and leader of Guarani women’s gatherings.
- The group was visiting relatives and sharing traditional seeds with Guarani communities facing land shortages. The semitrailer that struck them was carrying maize for industrial agriculture.

Scientists use mining data to build malaria alert system in the Amazon
- Researchers have found a direct link between illegal mining, miners’ routes, and malaria cases in the Yanomami Indigenous Territory in Brazil.
- Now, they’re working on an alert system that will rely on mining data to warn local health agents about the risk of a malaria outbreak.
- The number of malaria cases dropped sharply after authorities expelled illegal miners from the Yanomami land, but Indigenous people worry the potential return of a right-wing government after October’s election could revive the humanitarian crisis.

For 50 years, Philip Fearnside has calculated the costs of losing the Amazon
- Philip Fearnside has spent 50 years studying the practical limits of Amazon development, beginning with the agricultural settlements built along Brazil’s Trans-Amazonian Highway. His work repeatedly asked who benefits from projects and who bears their longer-term costs.
- He produced influential research on deforestation, forest carbon, tropical dams, and the wider effects of roads, often challenging official assumptions about emissions and economic viability. He later contributed to the IPCC’s work on climate change.
- Fearnside has paired research with public engagement, publishing in Portuguese, writing for Amazônia Real and Mongabay, speaking to journalists, and testifying on projects including the BR-319 highway. That role has also made him a target of hostility, including at a 2021 public hearing where his microphone was cut.
- Former students and colleagues credit him with generous, exacting mentorship and an unusual command of the scientific literature. At a recent tribute at Brazil’s National Institute for Amazonian Research, he rejected any suggestion of a farewell: he intends to keep working.

Under protection: The environmentalist’s widow in Brazil who had to disappear to survive
- In 2015, environmentalist Raimundo dos Santos Rodrigues was murdered in an ambush inside the Gurupi Biological Reserve in Brazil’s Maranhão state, where he served as a member of the advisory board.
- A local rancher, who was illegally logging inside the reserve, orchestrated the killing.
- Rodrigues’ wife Maria survived the attack but has spent more than 10 years living in another state in a government protection program.
- Maria experiences a contradiction in her new life: She had to be made invisible by the state to survive the state’s failure to investigate and prosecute socio-environmental crimes.

Brazil relaxes Belo Monte water rule amid El Niño-fueled Amazon drought risk

Tapirs, bats and nests: How plastic infiltrates Amazonian wildlife
- Studies have found microplastics in various species of Amazonian wildlife, including fish, tapirs, crabs and bats, even within protected areas far from major urban centers.
- Contamination spreads through multiple routes, traveling from small forest streams known as igarapés to the mouth of the Amazon River, where birds are building “blue nests” out of plastic debris.
- Although the toxic effects on animals remain poorly understood, data show that microplastics cross between aquatic and terrestrial ecosystems, potentially impacting the entire food chain.

As an industry and a cooking ingredient, seaweed is gaining ground in Brazil
- In Paraty, Brazil, a Caiçara family has transformed seaweed cultivation into gastronomy, educational tourism and a source of income. The venture is driven by strong female participation and a deep connection to their territory.
- Originally introduced in Brazil to supply the carrageenan industry, the macroalgae Kappaphycus alvarezii is also being used as a biofertilizer and increasingly as a food item..
- Its farming also supports ecological balance. It produces oxygen, absorbs carbon and helps improve water quality by filtering out excess nutrients.
- Experts say the expansion of seaweed farming in Brazil faces bottlenecks in credit, marketing, technology and regulation. New research networks and public policies are attempting to organize the sector as part of the country’s growing bioeconomy.

Fatal barge crashes fuel fear over Madeira River waterway expansion in Brazil
- Brazil is planning to dredge the Madeira River to boost grain exports despite recent fatal barge collisions and poor dialogue with local communities.
- In addition to accidents, expanded traffic and dredging pose risks of erosion, water pollution, harm to aquatic species and fishing.
- As national elections approach, communities worry that politicians will prioritize agribusiness over the safety of those who rely on the river to access doctors, schools, work, trade and daily routines.

Increasingly rare: Jaguarundi moves up a notch on the endangered species list
- The jaguarundi needs more attention, researchers say. This small cat, ranging from Mexico to Argentina, was recently recategorized from least concern to near threatened on the IUCN Red List.
- Despite the species’ large territory, monitoring data suggests it’s rare, now among the least abundant felids across its range. Conservationists also warn some populations are in decline due to human-wildlife conflict, dangerous roadways, attacks by dogs and infectious disease.
- With relatively little field study or funding for research, there are huge gaps in researchers’ understanding of this cat, but conservationists hope this change in conservation status will spark greater attention.

New studies portray Amazon as surprisingly resilient, but tipping point looms
- Three 2026 studies reveal that the Amazon can regrow quickly, but deforestation and warming could trigger a system-wide tipping point in the next 15 years.
- Research also shows that repeated wildfires are replacing fire-resistant specialist trees with generalist species, halving biodiversity at forest edges despite a closing canopy.
- According to research, extreme conditions have increased tree mortality due to hydraulic failure, which is key to understanding the forest’s shrinking carbon sinks.
- Ending deforestation is necessary and achievable, but must be combined with global actions to curb climate change, say experts.

How a Brazilian Indigenous ethnobotanist & elders recorded their people’s medicinal knowledge
- In an unprecedented participatory ethnobotany approach, Hemerson Dantas dos Santos Pataxó HãHãHãi, a Brazilian Indigenous ethnobotanist, documented alongside his people their traditional medicinal practices: cataloging 175 medicinal plants, many of which had their use reaffirmed in scientific literature.
- Mongabay visited Hemerson and spoke with several Indigenous elders who survived violent land conflicts about their medicinal knowledge and their efforts to protect it in the Caramuru/Paraguassu Indigenous Territory, a land illegally occupied by cattle farmers for decades in Brazil’s Bahia state.
- Samples of plants collected by Hemerson are being kept at an internationally registered herbarium, and he’s finalizing a book in the hope of keeping the knowledge of the species and ancestral healing practices alive for his people’s future generations.
- The work carried out with his people was essential to make “immortal” the knowledge of the elders, Hemerson said, describing them as “living libraries” and “Guardians of Memories.”

Brazil Supreme Court upholds laws that led to downfall of Amazon soy moratorium
RIO DE JANEIRO (AP) — Brazil’s Supreme Court has upheld state laws denying tax incentives to farmers who adhered to the country’s soy moratorium. The court also affirmed the constitutionality of the voluntary agreement. For nearly 20 years, the pact barred the purchase of soy grown on deforested Amazon land. Major grain traders withdrew from […]
Bolsonaro’s easing of gun control fueled illegal hunting, study indicates
- A new study points to the easing of gun restrictions during the administration of former President Jair Bolsonaro as a primary driver of illegal wildlife hunting in Brazil.
- By mapping social media posts, researchers documented more than 4,000 animals killed from 157 native species across the country, coinciding with a surge in gun purchases by sport hunters.
- The primary hotspots are concentrated in the Amazon’s Arc of Deforestation, where forest loss, environmental degradation, gun availability and agricultural expansion compound pressure on wildlife.
- Researchers are calling for stricter firearm controls, stronger law enforcement and coordinated conservation policies to curb an environmental impact they describe as silent and widespread.

Key Amazon cases reach Brazil’s Supreme Court following Lula’s defeats in Congress
SAO PAULO (AP) — Brazil’s Supreme Court is set to decide cases that could reshape protections for the Amazon rainforest and Indigenous communities. These cases involve Indigenous land rights, environmental safeguards, and infrastructure projects. Congress approved measures that environmentalists say violate constitutional rights, but President Lula vetoed some. Lawmakers overrode these objections, sending disputes to […]
Brazil’s wildcats face multiple diseases due to habitat fragmentation
- Throughout Brazil, the contact between domestic cats and wild felines has been exposing threatened, biologically vulnerable feral species to diseases, which can reduce their populations.
- According to experts, habitat fragmentation is a common denominator of this crisis, from the Amazon to the Pampa, where felines are forced to leave the boundaries of their native areas and approach sites modified by human action.
- From the imposing jaguar to one of the smallest and rarest, the pampas cat, no Brazilian feline escapes the risks of contracting fungi, bacteria, parasites, and known viral diseases, such as feline leukemia and others.
- Studies and veterinarians warn that mass vaccination of domestic animals and the preservation of natural areas are key pieces to address this problem.

Mariano Cenamo, advocate for a sustainable Amazon bioeconomy, has died, aged 46
- Mariano Cenamo spent more than two decades trying to make standing forests economically competitive with cattle ranching and other activities driving Amazon deforestation, helping establish Idesam and later backing a new generation of sustainable businesses.
- His work evolved from early efforts on forest carbon and REDD+ to agroforestry, bioeconomy ventures, investment, and entrepreneurship, always centered on creating practical sources of income for people living in the Amazon.
- Drawing on Cenamo’s own writings and interviews, as well as Vanessa Adachi’s posthumous portrait in Reset, this obituary explores the ideas, motivations, and personal style behind one of the Amazon’s most influential environmental entrepreneurs.
- Cenamo died on July 10 after several years with cancer. He was 46.

Amazon deforestation alerts fall to lowest level since 2013, Brazilian data show
- INPE’s DETER system recorded 2,874 sq km of Amazon deforestation alerts from August 2025 through July 2026, down 36% from the previous year and 55.6% below the preceding 10-year average.
- The total is the lowest since 2013 when earlier DETER data are included. If the trend is confirmed by the higher-resolution PRODES system, Brazil could record its lowest official Amazon deforestation rate since monitoring began in 1988.
- The decline has coincided with stronger environmental enforcement under President Luiz Inácio Lula da Silva. Alerts also fell in the Cerrado, Caatinga, Atlantic Forest, and Pampa, with the Cerrado reaching a five-year low.
- Despite the decline in clear-cutting, the Amazon remains vulnerable to logging, drought, forest degradation, and fire, which can cause substantial ecological damage without immediately appearing in deforestation statistics.

Amazon canopy bridges enable 15,000 wildlife crossings without a single roadkill
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries.

Brazil’s mining agency under fire over corruption and omission probes
- Federal prosecutors are suing the Brazilian mining agency for failing to monitor wildcat gold mines in the Brazilian Amazon.
- Illegal miners take advantage of the agency’s lack of oversight and name small areas as the origins of tons of gold that have actually been taken from protected areas.
- Measures implemented in the past few years have contributed to a sharp decrease in gold laundering in Brazil, but illegal metal is now being smuggled out of the country.
- ANM’s top officials are also under investigation for receiving bribes to favor mining companies.

Researchers find ‘priority zones’ for yellow fever vaccination of golden lion tamarins
- Golden lion tamarins, an endangered species of monkey endemic to Brazil’s Atlantic Forest, are susceptible to yellow fever: An outbreak in 2017-2019 wiped out roughly 30% of the population.
- A new study finds that certain environmental factors, including habitat connectivity and human population, were linked to higher numbers of deaths during the outbreak.
- Scientists have identified areas where tamarins could be at high risk for yellow fever transmission, which could help guide vaccination efforts and help protect the monkeys in the event of another deadly outbreak.

The global gold rush consuming the Amazon (commentary)
- Record gold prices and rising global demand are increasing the incentives for illegal mining across the Amazon, including in protected areas and Indigenous territories.
- Illicit gold can be laundered into legal markets through false documentation, shell companies, traders, and refiners, while mining damages rivers, forests, and communities through deforestation, sediment, mercury contamination, and diesel emissions.
- Central banks and other major buyers should impose stronger sourcing, traceability, audit, and due-diligence requirements to make illegal gold harder to sell, argues Robert Muggah, co-founder and research director of the Igarapé Institute.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

Indigenous Parakanã fear election U-turn may spark new invasions in Brazil
- The Parakanã Indigenous people are reoccupying their territory in Pará state after the eviction of around 3,000 invaders by federal forces.
- The intruders, however, are ready to come back if Brazil’s next administration carries a new anti-environmental agenda in 2027.
- Experts compare illegal activities such as gold mining to powerful bacteria that may return even stronger if you don’t use the proper antibiotic.
- Also in Pará, the state administration has the challenge of keeping deforestation under control after a successful operation in the Triunfo do Xingu Environmental Protection Area.

[…]
Fishers fight for solutions as Brazil lists tambaqui as threatened
- One of the most cooked fish in the Brazilian Amazon, the tambaqui was included in the official national list of threatened species, triggering fear of losses from Amazon small-scale fishers who depend on the species for their livelihood.
- The tambaqui was classified as vulnerable due to projections of a 43.4% overall population decline over three generations as it’s targeted by intense fishing.
- Starting at the end of October, its fishing could be prohibited in Brazil if a recovery plan isn’t implemented, according to the Ministry of Environment and Climate Change.
- The gray triggerfish was also included in the list of 490 fish and invertebrate threatened fauna, triggering reactions from artisanal fishers and the fishing industry.

End of Brazil’s Soy Moratorium risks millions of hectares of Amazon rainforest: Study
Millions of hectares of Amazon rainforest are newly at risk of being legally deforested, a new study estimates. The potential increase in deforestation comes as soy companies have terminated their voluntary participation in the Amazon Soy Moratorium, a private-sector agreement that barred signatories from buying soy grown on land deforested after 2008. Researchers found 9.1 […]
Khuiusi Khisêtjê helped his people recover their land and future in the Xingu
- Khuiusi Khisêtjê assumed leadership after disease and violence reduced his people to around 50 and killed many of their elders.
- He helped recover the Wawi Indigenous Territory, which contained ancestral villages, sacred places, and the graves of Khisêtjê relatives.
- He worked to preserve Khisêtjê songs, language, oral history, and cultural knowledge while preparing younger leaders to navigate Brazilian institutions.
- As soy farms and pesticide use expanded around the territory, he continued defending the land and, in 2018, led his community deeper into the forest.

Scientists call on countries to act on ‘forgotten’ sawfish teeth trade
- Teeth of critically endangered sawfish species continue to be used as cockfighting spurs in Latin America despite bans from cockfighting organizations, a new study found.
- Researchers interviewed cockfighting practitioners in Peru, where the sport is widely prevalent, and leaders from cockfighting associations in Peru, Mexico, Ecuador and Puerto Rico to understand the dynamics of this illegal trade.
- The study found sawfish teeth are sold for anywhere between $25 and $400 per pair, making them some of the most valuable wildlife products. Peru, Ecuador, Costa Rica, Brazil and Colombia supply most of the teeth, while Peru tops the list of consumers.
- All commercial international trade in sawfish is prohibited under CITES, and the fish is a protected species across Latin America. Scientists call on countries to enforce their laws and on CITES to act against hidden illicit trade.

For Brazil’s Xokleng people, saving a sacred tree means saving their culture
- The Zág Institute, an initiative of the Laklãnõ/Xokleng Indigenous people, is restoring the Brazilian pine on their traditional territory in the state of Santa Catarina.
- Sacred to the Indigenous people, the Brazilian pine is a critically endangered species; replanting it is seen as a way of strengthening their identity.
- Nearly 100,000 seedlings have been planted across 1,000 hectares (2,500 acres), in the process restoring water sources and degraded land.
- The reforestation project involves the whole community in planting the seedlings, which is done through collective efforts throughout the year and also by donating them to Indigenous families.

Health fears linger in a Brazilian neighborhood built over oil waste
- Official documents show the historic presence of benzene and other contaminants in São Sebastião’s Itatinga neighborhood. Despite reports of illnesses, an epidemiological study planned for assessing the impacts on the population has never been conducted.
- Documents from multiple agencies show the historic presence of oil-derived contaminants, including benzene, in a residential area of the Itatinga neighborhood in São Sebastião, São Paulo.
- For decades, locals have reported cases of cancer, vision loss and respiratory and neurological problems, but a main study intended to look into the health impacts of exposure has never been conducted.

Amazon tree rings reveal more intense drought and rainfall in the rainforest
Tree rings from the Amazon show that the world’s largest rainforest has developed wetter wet seasons and drier dry seasons over the past four decades. The findings point to intense seasonal swings that can cause significant harm to biodiversity and suggest that widespread drying out across the entire Amazon basin is unlikely. Researchers collected tree […]
Zero roadkill as Amazon canopy bridges secure 15,000 crossings
- Project Reconecta installed eight rope bridges in a municipality in Brazil, and a 15-month study used camera traps to document thousands of arboreal wildlife adapting to new aerial crossings.
- Safe road passages enable seed dispersal and gene diversity, reversing the “domino effect” of biodiversity loss that begins when highways split habitats.
- Reconecta’s creator, biologist Fernanda Abra, a National Geographic Explorer and winner of the Whitley Award, is now expanding these low-cost conservation tools to other Brazilian biomes and neighboring Suriname.
- Brazil’s federal transport department has officially designated the rope bridge design as the recommended national standard for highways to curb the millions of wildlife deaths recorded on roads annually.

Renato Moraes de Jesus was a pioneer of Atlantic Forest restoration in Brazil

Can harpy eagles attack humans? Amazon case rekindles scientific debate
- An attack by a harpy against a tourist in French Guiana has sparked a debate about interactions between humans and the world’s largest eagle.
- Field reports indicate that these episodes are uncommon and usually associated with defending prey, but they can result in serious injuries.
- Although rare, these cases expose a conservation dilemma: They may reinforce stigma against the species but also reveal real conflicts about which there is little public debate.

Amazon deforestation falls to 10-year low in first half of 2026
Deforestation in the Brazilian Amazon has fallen to its lowest level in the past 10 years, according to satellite data published by Brazil’s National Space Agency (INPE). Between January and June 2025, a total of 2,090 square kilometers (807 square miles) of deforestation was recorded in the Brazilian Amazon. In the same months of 2026, […]
Invasive giant prawn spreads through protected areas in Brazil
- A study led by researchers from Brazil and Uruguay confirmed the presence of invasive prawns in several conservation areas along the Brazilian coast, including estuaries listed by UNESCO as Natural World Heritage Sites.
- Considered an opportunistic predator and highly adaptable to different marine conditions, the giant river prawn competes with native species for food and shelter, in addition to being a potential vector for diseases.
- While scientists demand concrete actions to stop the advancement of this intrusive crustacean, small-scale fishers report significant drops in their capture of native animals, warning about the impact of invasive species on their livelihoods.

Meat giant JBS silently ditches bolder environmental targets in latest review

Brazil lists the Amazon river turtle as endangered for the first time
- The cágado-iaçá, or six-tubercled Amazon River turtle, had its risk elevated from near threatened to endangered, entering Brazil’s official list of fauna species threatened with extinction for the first time.
- Despite protection and conservation efforts, cágado-iaçá’s populations over the past 36 years declined by more than 50% in Amazonas and western Pará states, according to official data.
- The species is widely consumed in the northern region, alongside the yellow-spotted river turtle and the Amazon turtle, which remain in a less concerning category, according to ICMBio.
- The hyacinth macaw, the black howler monkey and the red silky anteater were reclassified as vulnerable, adding to the list of 790 species recently published.

How Brazil’s federal fiscal policy hinders Amazon Rainforest conservation (commentary)
- The three Brazilian states whose territory is mostly Amazon Rainforest — and carry the heaviest share of its conservation burden — are among the poorest and most fiscally dependent in the country.
- Amapá, Acre, and Amazonas operate on budgets so dependent on federal funding that they have almost no ability to act on their own, yet they are also precluded from developing their economies within their vast and federally protected swaths of forest.
- “It is a design flaw in Brazil’s fiscal constitution, and it is getting worse,” a new op-ed argues. “Brazil cannot credibly lead global climate diplomacy while its Amazonian states remain fiscally trapped.”
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

Rising seas, garbage and heat threaten Brazil’s migratory shorebirds
- Among the many effects linked to climate change and damages to estuarine ecosystems, research indicates that migratory birds that depend on coastal wetlands could lose half of their habitats by 2050
- The impact is significant for Brazilian shorebirds: besides depending on a continuous chain of healthy wetlands to complete their long journeys between hemispheres, they suffer from the degradation of feeding areas such as mangroves.
- One the most threatened species is the red knot (Calidris canutus): low food availability could impair the bird’s preparation for the 8,000-kilometer (5,000-mile) journey it makes from Brazil’s northeast coast to the U.S. coast.
- Researchers are conducting censuses and conservation projects in areas of high shorebird biodiversity, including the Potiguar Basin in Brazil’s Rio Grande do Norte state, considered a “regionally important site” for these migratory birds.

Lydia Möcklinghoff, champion of the giant anteater, has died in a plane crash. She was 45
- Lydia Möcklinghoff, a German biologist and science communicator, died on July 3, 2026, aged 45, in a plane crash near Campo Grande, Brazil, during a flight connected to Pantanal fieldwork.
- She became one of Germany’s leading experts on giant anteaters, turning a little-understood animal into the focus of serious field research, public writing, radio reporting, and children’s science communication.
- Her work combined patience, humor, and precision, linking the behavior of anteaters to larger questions about habitat, fire, drought, land use, and the future of the Pantanal.
- Through books, columns, podcasts, films, and WDR’s MausRadio, she helped readers and listeners see that overlooked species are worth studying, explaining, and protecting.

Dark earth: Ancient Amazonian soil can boost forest restoration, study finds
- Researchers from the University of São Paulo and the Brazilian Agricultural Research Corporation showed in a study that the ancient organic-rich soil known as Amazonian dark earth (ADE) boosted seedling growth under real field conditions.
- The investigation suggests ADE could work as a “biological engineer” by reshaping the soil’s microbiome, increasing beneficial fungal diversity and reducing pathogenic microbes that hinder tree growth.
- With conservation in mind, scientists are now working to isolate these micro-organisms to develop bioinputs for forest restoration without disturbing the original Amazonian dark-earth deposits.

Brazil boosts budget and number of firefighters amid strong El Niño forecast

The El Niño climate pattern, which emerges from unusually warm waters in the tropical Pacific, typically […]
Brazil’s expanding offshore oil frontier puts biodiversity at risk: study
- Fossil fuel exploration off the northeast coast of Brazil presents a greater cumulative risk of oil spills than previously expected, according to new modeling.
- Seagrass meadows and deep-water reefs in the Potiguar Basin are at greatest risk, as well as portions of the coasts of Ceará, Rio Grande do Norte and Amapá states.

- In early 2023, civil society pressure put the road at the top of the government’s agenda, leading to enforcement operations and a sharp decline in new illegal road openings across the Xingu Basin.
- Conservationists warn the gains remain fragile: Invaded Indigenous territories face violent backlash, illegal mining is regrouping, and this year’s elections could redefine Brazil’s environmental policies.
