Biological communities are organised at multiple functional spatial scales and interactions between these scales determine both local and regional patterns of species richness. Despite the recognition that species-environment relationships are scale-dependent many ecologists have neglected the influence of scale on species richness patterns and processes. We analysed the influence of spatially explicit bio-physical variables on a bird community in a Mexican region denominated as an important area for bird conservation. Using a multiple scale approach with plot, patch and landscape level variables using abundance and presence-absence data, we demonstrated that landscape variables explained most of the variation in bird species in both abundance and presence-absence analyses in all explanatory sets. Interestingly, results demonstrated that variation in community structure was described best at family-level than at genera- or species-level. In addition, shade coffee plantations could provide habitat forneo-tropicalmigrants and forest-dependent birds (e.g.; endemic, protected species). Selecting the appropriate scale(s) of management in conservation strategies could have important implications for conservation of bird communities in Cuetzalan region.
