                         mammals concerning their population densities. However, few 
                         studies have evaluated the factors that influence the spatial 
                         variation in the population density of primates, which limits the 
                         possibility of inferences towards this animal group, especially at 
                         the landscape-level. Here, we compiled density data of Sapajus 
                         nigritus from 21 forest patches of the Brazilian Atlantic Forest. 
                         We tested the effects of climatic variables (temperature, 
                         precipitation), landscape attributes (number of patches, mean 
                         inter-patch isolation distance, matrix modi- fication index) and 
                         patch size on the population density using linear models and the 
                         Akaike information criterion. Our findings showed that the density 
                         of S. nigritus is influenced by landscape attributes, particularly 
                         by fragmentation and matrix modification. Overall, moderately 
                         fragmented landscapes and those surrounded by matrices with 
                         intermediate indexes of temporal modification (i.e., crop 
                         plantations, forestry) are related to high densities of this 
                         species. These results support the assumptions that ecologically 
                         flexible species respond positively to forest fragmentation. 
                         However, the non-linear relationship between S. nigritus density 
                         and number of patches suggests that even the species that are most 
                         tolerant to forest cover changes seem to respond positively only 
                         at an intermediate level of habitat fragmentation, being dependent 
                         of both a moderate degree of forest cover and a high quality 
                         matrix. The results we found here can be a common response to 
                         fragmentation for those forest dweller species that are able to 
                         use the matrix as complementary foraging sites.",
