Abstract (en):
The present work evaluates the accidental mortality for collisions over wildlife and vehicles associated to
the road that going from Toluviejo town to Ciénaga de la Caimanera in the department of Sucre, Colombia,
crossing an important portion of Montes de María, it passes through by antropic savannas until arriving to
the area of mangroves in the Caribbean coast. Were registered 431 individuals road killed: mammals 28,1 % (121), birds 28,8 % (124), reptiles 21,8 % (94) and amphibians 21,3 % (92). Specifically the species with more mortality were: Cerdocyon thous (10.9 %), Iguana iguana (10.8hj%), Crotophaga ani (9.5%), Tamandua mexicana (7.7 %) and Didelphis marsupialis (6.1 %). The rate runover was superior in all the cases, both as, in a general and as specified way when comparing it with related works. The analyzed road doesn't present any signaling protection for the wild fauna, it lacks illumination, and it is built in its entirety in asphalt, with relative good state. The running over rate it is related to factors such as: vehicular flow, wide of the road, behavior of the species, vegetable covering and the vehicular speed, being all of great importance and wide influence in the detected road killed.
Abstract (es):
El presente trabajo evalúa la mortalidad accidental debida a atropellamiento de fauna silvestre en la carretera que va desde el poblado de Toluviejo a la ciénaga de La Caimanera, departamento de Sucre, Colombia. Esta atraviesa una porción de los Montes de María, pasando por sabanas antrópicas hasta llegar a una zona de manglares en la costa Caribe. Se registraron 431 individuos atropellados, de 31 especies: mamíferos 28,1 % (121), aves 28,8 % (124), reptiles 21,8 % (94) y anfibios 21,3% (92). Específicamente las especies con más atropellamientos fueron: Cerdocyon thous (10,9%), Iguana iguana (10,8 %), Crotophaga ani (9,5 %), Tamandua mexicana (7,7 %) y Didelphis marsupialis (6,1 %). La tasa de atropellamiento fue superior en todos los casos, tanto de manera general como específica, al compararla con trabajos relacionados. La vía analizada no presenta señalización para la protección de la fauna silvestre, carece de iluminación, está construida en su
totalidad en asfalto y en relativo buen estado. La tasa de atropellamiento está relacionada con factores como flujo vehicular, ancho de la vía, comportamiento de las especies, cobertura vegetal y velocidad, siendo todas de gran importancia y de amplia influencia en los atropellamientos detectados.
