On November 10, 2015, large numbers of white-lipped peccaries moved across the town of Caracaraí in Roraima State, Brazil.  Many became trapped in yards or were killed by townspeople.  Caracaraí 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 Caracaraí 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.

Map Rupununi

Anthony Ravindra Cummings led the Project Fauna team in the production of a vegetation map for the Rupununi region of Guyana, with the participation of Makushi, Wapichana and other Amerindians. Cummings and co-authors Jane Read (Syracuse University, USA) and Jose Fragoso state that with hunter’s vegetation descriptions and remotely sensed imagery we produced an eleven-class vegetation map that covered the main vegetation types described by hunters. “The final map shows that indigenous hunters can be important partners in the map-making process…”.

Stanford University produced a short documentary of our monitoring of plants and animals of the Amazon. Watch amazing scenes of caimans, capybaras, tapirs, giant anteaters, giant otters, macaws and other unusual creatures filmed during our field studies. The interview focuses on the successful monitoring of these animals by indigenous people. The take home message is that indigenous people use wildlife in a sustainable fashion.

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:
