Caracterização da paisagem de Sapajus flavius (Primates, Cebidae) e Alouatta belzebul (Primates, Atelidae) na Mata Atlântica nordestina

Abstract

The effects of fragmentation process and habitat loss have generally resulted in the decrease of species richness, abundance of species, density of species and changes in the distribution of the population, and the reduction of genetic diversity. The arboreal primates are the most sensitive species to habitat fragmentation and the change in habitat quality may affect the disposition of primates group along fragment and cause behavioral changes. In this study we evaluated the landscape structure in the locations that occur both primates species endangered in Atlantic Forest north of the São Francisco River, Alouatta belzebul and Sapajus flavius. Our analyzes suggest that there is no difference between the fragments which these species occur in relation to the landscape metrics used, although some species of primates show sensitivity metric somehow, even so, some fragments are too small, or even distant of other fragment thus showing the need for greater conservation both species. In this chapter emphasizes the importance of having large fragments when there is occurrence of more than one species and a better connection between fragments when these are smaller to facilitate the migration of primates among the fragments.
