DEFLER, Thomas R.. SPECIES RICHNESS, DENSITIES AND BIOMASS OF NINE PRIMATE COMMUNITIES IN EASTERN COLOMBIA. Rev. acad. colomb. cienc. exact. fis. nat. [online]. 2013, vol.37, n.143, pp.253-262. ISSN 0370-3908.

This is a preliminary comparison of nine primate communities from Colombian Llanos and Amazonia, including three communities in Llanos gallery forest and six communities from the Amazon basin. Total primate biomass in the extreme eastern Colombian Amazon is considerably lower than reported at other sites at longitudes of 5°-8° south of the Amazon-Solimões in Brazil and Peru. Primate richness at the Colombian sites (up to 10 sympatric species) was below that found at other sites in Brazil and Peru (up to 14 sympatric species), where the highest neotropical species richness seems to be situated. Although primate species richness was reduced in the Colombian gallery forest sites, biomass per community surpassed terra firme moist eastern forest sites, but was comparable to biomass of the only black-water igapó forest in this study.

Keywords : primate communities; primate densities; primate biomass; primate species richness; Colombian Amazon.
