Vulnerable island carnivores the endangered endemic dwarf procyonids from Cozumel Island
Insular carnivores represent some of the most critically threatened species, but also the least known. To evaluate the conservation status of these species, thorough abundance estimates are urgently required. To better understand the population biology and conservation status of the endemic and threatened pygmy raccoon (Procyon pygmaeus) and dwarf coati (Nasua nelsoni) on Cozumel Island, Mexico, we worked island-wide to identify the presence of these species, and for the pygmy raccoon we studied several populations in depth during 2001-2003. On Cozumel, trapping was conducted for >6,600 trap nights in 19 locations of varying habitat types.
