In this paper, we summarize and examine recorded ecological effects of roads and infrastructure on vertebrates populations. A review of the literature showed that roads cause decline or extinction in vertebrate populations, promote forest fragmentation, facilitates access for resource extraction and exploitation, and precipitates the creation or consolidation of new human settlements, in neotropical forests. In developing countries, roads are conceived as necessary interventions to improve life standards of rural inhabitants. It is crucial for conservation and sustainable development decisions to have reliable information on the effect of roads (or infrastructure) in Neotropical areas. Not all types of roads and species respond or interact in the same way. Our results suggest that the area influenced by a road can be described as a function of road types and the ecology of the species. Populations of specialists tend to decline, whereas generalist species can even increase. Animals wich narrow habitat requirements are more susceptible to the effect of roads and infrastructure.
