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

New Publication: Line Transect Surveys Underdetect Terrestrial Mammals: Implications for the Sustainability of Subsistence Hunting

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.

New Publication: Socio–environmental sustainability of indigenous lands: simulating coupled human–natural systems in the Amazon

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!

Research collaborators Takuya Iwamura, Eric Lambin, Kirsten Silvius, Jeffrey B Luzar, and José Fragoso have a new paper in press. The publication examines the resiliency and sustainability of biodiversity, human livelihoods and forest cover within Amazonian indigenous lands under various future development scenarios. The paper is scheduled for publication in the February 2016 issue of the journal “Frontiers in Ecology and the Environment”
