Geography of roadkills within the Tropical Andes Biodiversity Hotspot: Poorly known vertebrates are part of the toll

Biotropica, Volume 53, Issue 3, Page 820-830, May 2021., 2021
We analyzed wildlife roadkill patterns along a road network between tree protected areas in the Andes of Ecuador. Roadkills included poorly known small and endemic vertebrates, such as caecilians (Gymnophiona) and fossorial snakes (Atractus spp.). Most roadkills occurred in areas where roads crossed pasturelands adjacent to natural habitat.
