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 “Community livelihoods depend upon accurate wildlife estimates”
On November 10, 2015, large numbers of white-lipped peccaries moved across the town of Caracaraà in Roraima State, Brazil. Many became trapped in yards or were killed by townspeople. Caracaraà has a population of over 10,000 people.  Jose Fragoso (1997, 2004) described these exceptional movements as possible population level dispersal events or perhaps a herd that abandoned its usual home area after long term persecution by humans.

More than 170 white-lipped peccaries were filmed crossing the Rio Branco River in Caracaraà County, Roraima, Brazil in the Amazon. The peccaries were filmed for over 30 minutes when in the middle of the almost 2 km wide Rio Branco by agents of Brazil’s wildlife agency Ibama. Recording made on November 7, 2015.

We have completed a major work describing the sustainability of hunting, farming (land use) and local livelihoods in the tropics. We devised an agent based computer simulation model and explored the relationships between the above mentioned elements to consider what the future may hold for tropical forest biota, ecosystems and peoples.
Stanford University, Mongabay and others published news reports about the work. You can view two here: http://news.stanford.edu/news/2014/june/amazon-sustainability-model-061314.html
