Ecological Biogeography of Primates in Guyana

摘要: One of the goals ecological biogeography is to determine correlates species diversity and abundance in biological communities. Although large-scale disturbances, such as deforestation, have been linked declining mammal population sizes tropical forests, effects less severe forms natural disturbances (flooding, black water swamps) anthropogenic (logging, hunting, agriculture) are poorly understood. Moreover, interspecific associations may influence presence or absence primate species. We used data from 2108 km surveys we conducted 1994–1997 eight Guyana.
