Abstract
Population density of Saguinus leucopus in forest remnants with different physical and biological features. Saguinus leucopus is an endemic primate of Colombia. It has a very small distribution on the Andean region of Colombia from 0 to 1500 m asl. This is one of the regions where more habitats are lost by human activities. S. leucopus is an endangered species because of its small distribution area and habitat loss. Our first goal was to compare the population density of S. leucopus in forest patches of different alteration level. The second goal was to evaluate the relationship between population density and the size, isolation distance, shape and altitude of the patches. The final goal was to evaluate its association with plant diversity, and tree density of the forest patches. Population density was estimated using distance sampling with line transect. The population densities were 37 to 149 Individual/km2. We found differences between some patches. Population densities of S. leucopus in the seven patches were separated into three homogeneous groups. Using Poisson regression, we found that population density of S. leucopus increases at higher altitudes and when the patch is more elongated. There was not significant association between population density and plant diversity and structure. © SAREM, 2011.
