Abstract: Roads are widespread and increasing feature of most landscapes.The road networks increase the society wealth and make people's life more convenient,whereas they also result in serious ecological problems.We reviewed the ecological effects of roads on terrestrial animals.There are five general effects: mortality from road construction and collision with vehicles,which has been a primary lethal factor for vertebrates; barrier to movements between conspecies populations and complementary resources for individuals of terrestrial animals; road avoidance of forest-interior and edge-sensitive species; reproduction depression of the avian; and biotic invasion facilitated by dispersal of small wildlives along road edge.Road verge,as a special edge,is an ecological mortality trap for edge species and other animals attracted onto the physically and chemically modified environment of road habitat.The problem of isolated small population can be exacerbated by the combined impacts of those five effects above,which will inevitably reduce the persistence probability for populations of the vulnerable and endangered wildlives.
