TRáFICO DE MONOS NOCTURNOS Aotus SPP. EN LA FRONTERA ENTRE COLOMBIA, PERú Y BRASIL: EFECTOS SOBRE SUS POBLACIONES SILVESTRES Y VIOLACIóN DE LAS REGULACIONES INTERNACIONALES DE COMERCIO DE FAUNA ESTIPULADAS POR CITES

this study describes significant levels of trade of night monkeys (aotus nancymaae, a. vociferans and a. nigriceps) at the brazil-colombia-peru tri-border area for the malaria biomedical research market. interviews with 43 traders/collectors from the three countries suggest that for the period 2007-2008, around 4000 night monkeys were traded. census at 8 localities in peru and colombia reported contrasting population density estimates for aotus (peru: 3,6 ind/km2; colombia: 44 ind/ km2). it is critical for cites regulations to be enforced at the 3 countries in order to curb the decline of wild populations of aotus and the degradation of their habitat.
