Plastic pollution is widespread across the Amazon Rainforest’s rivers, plants and animals, according to a recent study. Previous research suggests up to 10% of total plastics in the ocean arrive there via the vast network of waterways that’s the Amazon Basin. To understand how and where plastic pollution is present within the basin itself, researchers […]
Scientists warn that “flying rivers” — invisible streams of moisture that carry rain from the Atlantic Ocean westward across the Amazon — are weakening as deforestation and climate change advance.
The Amazon biome, stretching over a vast area across nine countries in northern South America, is renowned for its extreme diversity (biological and cultural) and its abundant water resources. Indeed, the major features of the Amazon are linked by interconnected water flows, both on land and in the air (Beveridge et al. 2024). The natural […]

What's the difference between telling someone's story and sharing it? We are committed to our collaboration with our partners, the Indigenous Maijuna of Peru - and this means that it's their story to tell. It's our privilege to share it. Our ongoing work is to do this well. This video was produced in close collaboration with the Federación de Comunidades Nativas Maijuna (FECONAMAI) and they have given us permission to share it with you.
Free Lesson from Subjet to Climate: In this interdisciplinary lesson, students learn about the benefits of the Amazon rainforest and the technology-based solutions that people are using to protect it.
For the first time in history, the world’s largest climate conference is heading to the heart of the Amazon. From November 10 to 21 2025, Belém do Pará, a vibrant city rich in biodiversity and culture and home to 1.3 million people, will host the 30th Conference of the Parties to the United Nations Framework […]
The frog’s loud croaking turned out to be a call to its own demise. The researchers walking along the steep muddy bank on a rainy November day in 2022 in the Imeri Range on the Brazil-Venezuela border were alerted by the unfamiliar sound. They found the frog sitting outside the opening to a tarantula’s burrow […]
The Amazon Basin is a biodiversity hotspot, with vertically stratified forests fostering complex habitats and high mammal diversity. Although mammals play a critical role in maintaining ecosystem structure, less is known about arboreal mammal activity and habitat use across forest canopy layers. As forest fragmentation increases, understanding how these changes impact arboreal species is essential for effective conservation efforts. Here, we provide a snapshot of canopy walkway use by arboreal mammals in an Amazonian forest with unfragmented canopy cover, providing insight into their spatial and temporal movement patterns across different canopy layers. This study was conducted at the Amazon Conservatory for Tropical Studies, in the Napo-Sucusari Biological Reserve outside Iquitos, Perú. During a three-week survey, we deployed camera traps at multiple heights along a canopy walkway system to monitor arboreal mammal activity. A total of seven mammal species used this canopy walkway system during our study period. Linnaeus’s two-toed sloth (Choloepus didactylus) and the long-tailed porcupine (Coendou longicaudatus longicaudatus) were the most commonly observed species, with several observations of the more reclusive and data-deficient C. ichillus also recorded, among other species. Peak activity occurred between 1900 and 2100 h, coinciding with higher temperature and humidity than nighttime averages. Mid-canopy layers (ca. 21 to 27 m above ground) were most frequently used, with decline in use at higher and lower canopy layers. Our findings provide baseline data on arboreal mammal use of canopy walkways in a tropical forest, which may help inform the design of human-created arboreal corridors to connect forest fragments.
Inspired by naturalist Alfred Russel Wallace’s visit nearly two centuries ago, an isolated Indigenous community in Brazil worked with scientists to survey local birds and documendocument cultural traditions. In doing so, they flipped the script of how research gets done.

Grâce à la connexion satellitaire, cette communauté indigène du nord-est péruvien peut désormais alerter en direct, surveiller son territoire et raconter sa culture au monde. Un outil qui change leur quotidien et pourrait peser dans la protection de l’Amazonie.
This memoir is a creative account of Dr. Brian Griffiths’s research on mammal ecology and conservation conducted in collaboration with the Indigenous Maijuna people of Peru.
