Abstract

The highways play a key role on the country’s social and economical development, for it’s use as an overland transportation route of people and truckloads. However she is seen as a threat to biodiversity, especially to the vertebrates. It can be considered a human action that generates extense impacts on natural environments, with direct and indirect consequences over the biota. One of the direct effects is the fragmentation of habitats that threatens several species, dividing it in little fragments and therefore restraining their movements. Another direct effect is the running over of wild animals that is considered 7 by a serie of authors as the main anthropic factor responsible for the death of wild vertebrates, overcoming the hunt.
