RESUMEN
El atropellamiento vehicular de fauna es un problema generalizado alrededor del Mundo pero escasamente estudiado en las carreteras colombianas, especialmente en áreas periurbanas. Aquí se describe la mortalidad de mamíferos entre los años 2008 a 2013 en la vía El Escobero (Envigado, Antioquia). Los mamíferos más atropellados en este periodo fueron los marsupiales (54.3 %), los carnívoros (25.7 %) y los roedores (17.5 %). Aunque en general se encontró una menor diversidad y un menor número de individuos atropellados que en años anteriores en la misma carretera, se reporta un número mayor de algunas especies desconocidas y amenazadas tales como Leopardus tigrinus, Puma yagouaroundi y Bassaricyon neblina. Este estudio también adiciona tres nuevas especies a la lista de atropellamientos de fauna de esta carretera.
ABSTRACT
Vertebrate roadkills is a generalized problem around the world but scarcely documented on Colombian roads, especially in periurban areas. Here it is described roadway mortality of mammals in a six year-period (2008-2013) on the El Escobero road (Envigado, Antioquia). Mammal groups that presented the greatest mortality were marsupials (56 %), carnivores (24 %) and rodents (18 %). Although there was a general lower diversity and lesser individual number of fatalities than previous years for the same road, this study reports a greater number of fatalities for some endangered and unknown species such as Leopardus tigrinus, Puma yagouaroundi y Bassaricyon neblina. This study also added three new species to the roadkill list on this road.
