Abstract
This work presents data on the relative diversity, abundance, and distribut ion patterns of primates in a 20 km(2) area of the Tapiche River in the Per uvian Amazon. Population data were collected while the study area was both inundated and dry (March to September 1997) using conventional line-transec t census techniques. Survey results reflected the presence of 11 primate sp ecies, but population parameters on only eight of the species will be prese nted, including saddleback tamarins (Saguinus fuscicollis), Bolivian squirr el monkeys (Saimiri boliviensis), brown capuchins (Cebus apella), white-fro nted capuchins (Cebus albifrons), monk sakis (Pithecia monachus), red titi monkeys (Callicebus cupreus), red uakaris (Cacajao calvus), and red howler monkeys (Alouatta seniculus). Woolly monkeys (Lagothrix lagotricha), night monkeys (Aotus nancymaae), and pygmy marmosets (Callithrix: pygmaea) were a lso seen in the area. The data for the smaller-bodied primates is similar t o that reported almost 18 years earlier, but the data for the larger-bodied primates reflect a loss in the number of animals present in the area. Pres sure from hunters and the timber industry may account for declining numbers of large bodied primates, while it appears that natural features peculiar to the conservation area contribute to the patchy pattern of distribution.
