ContextPrimates are an important component of biodiversity in tropical regions. However, many studies on the effects of habitat change on primates ignore the relative influence of landscape composition and configuration.ObjectivesThis study addresses the question: how important are landscape-scale forest area and composition relative to patch-scale (1–1080 ha) and site-scale (transect of 1 km) habitat variables for the occupancy and abundance of four primate species in the Colombian Llanos.MethodsUsing a randomly stratified survey design, 81 fragments were surveyed for primate occupancy and abundance. We used zero-inflated models to test the relative influence of landscape-scale, patch-scale and site-scale variables on occupancy and abundance for each species. A 95% confidence set of models was constructed using the cumulative Akaike weight for each model and the relative importance of each set of variables calculated for each primate species.ResultsOccupancy was determined by a combination of site-scale, patch-scale and landscape-scale variables but this varied substantially among the primate species.ConclusionOur study highlights the importance of managing primates at a range of scales that considers the relative importance of site-, patch- and landscape-scale variables. |
