The Amazon rainforest may be home to more animals than previously thought, Stanford scientists show

News report from Stanford University on our research: “By tapping the expertise of indigenous hunters, researchers found that conventional surveying techniques underestimate animal populations and miss species in the remote Amazon. Producing an accurate count is important for planning conservation efforts.” Continue reading

News article from Virginia Tech University on our research: “Evidence of wildlife passage, such as tracks, scat, fur, and disturbed surroundings, is a more accurate tool for assessing wildlife conservation status than actual encounters with animals, according to an international team of scientists from six universities, publishing in the April 13, 2016, issue of PLOS ONE.” Continue reading

Our new paper in the journal PLOS ONE reports that we are grossly under-detecting hunted animal species.  The results challenge the many studies showing serious negative impacts of subsistence hunting on wildlife species.  Seems like the animals may be hiding from us.  This research indicates that we need to reassess how we measure hunting impacts in the tropics.

“Populações habitam a região amazônica há milhares de anos, mas o avanço de elementos da vida moderna está pondo em risco a sustentabilidade desses povos e do ecossistema onde vivem. Essa é a conclusão de um estudo elaborado pela equipe do biólogo português José Fragoso, da Universidade Stanford, nos EUA.” “ — Os resultados da pesquisa mostram que apenas não invadir áreas indígenas não é suficiente — diz Fragoso. — O que acontece no entorno das reservas tem grande impacto no interior.”

Stanford University reports on how our computer model simulating sustainability sheds light on how modern interventions can affect tropical forests and indigenous peoples. Our computer simulation shows that carefully designing government interactions with rural indigenous people is critical for protecting the sustainability of people, wildlife and the land.

Our latest publication is out in Frontiers in Ecology and The Environment. We examine the socio-environmental sustainability of protected areas inhabited by indigenous and rural peoples and describe how socio-ecological change and development (e.g., forest clear-cutting outside indigenous areas, religious conversion, improved child mortality rates and introduction of resources from outside) outside these areas influences the sustainability of biodiversity, forest cover, and people inside. There are some surprising results so read the publication!
