Primatas das áreas litorâneas da região Norte do Brasil (primates: platyrrhini).

Abstract

The coastal area of the Amazon harbors representatives of most of the 14 genera of primates that occur throughout the region, many of which are endemic and/or endangered. Basic surveys on geographic distribution, biology or ecology are essential for long-term conservation of these animals. The study area (approximately from Oiapoque to the Gulf of Maranhão - Amapá, Pará and Maranhão) is referred to in taxonomy only as a definitive limit, disregarding ecological factors influencing the geographical distribution of monkeys. Reviews in systematics, ecology, behavior and conservation, as well as the inventory and mapping of localities recorded in the literature and scientific collections have allowed the identification of the forms of Amazonian primates that occur along the coast, their habitats and conservation status, thus relating their geographic distribution with coastal vegetation formations and environmental protection areas. The still preliminary results indicated the presence of 21 primate forms in the area (about 12% of the Brazilian forms), representing 10 genera (62% of the Brazilian genera), some of which with very restricted distribution, including 11 endemic to Brazil.
