CACERES, Nilton C; CASELLA, Janaina  e  DOS SANTOS GOULART, Charla. Spatial and seasonal variation of mammal road kill in the BR-262 highway, Cerrado biome, southwestern Brazil. Mastozool. neotrop. [online]. 2012, vol.19, n.1, pp. 21-33. ISSN 0327-9383.

The composition and abundance of mammal road kills were examined on two stretches of the BR-262 Federal Road, besides relationship between city distance and road kill, road-kill spatial distribution, seasonality effects, and relationship with vehicles daily volume. The killed animals were registered over 2 years and 4 months, between Campo Grande and Miranda, in southwestern Brazil. A total of 231 mammal specimens was found, which were distributed in 20 species, being Carnivora, Cingulata and Pilosa the main orders. The road-kill frequency was more intense far from big urban centers. Analyzing the spatial distribution of road kills, Cerdocyon thous and Tamandua tetradactyla showed defined peaks of road kill, in specific sites of the road, being also seasonally marked. There were no differences in the species richness between road stretches or between seasons. However, the number of road kills was higher in the stretch near the Pantanal biome, with emphasis to Carnivora and Pilosa. Overall, there were more road kills during the rainy season, with Cingulata as the main order. Management recommendations are done in order to diminish the road impact, such as the use of road sign in critical locations for road kills, use of fences for faunal contention in critical stretches, and facilitation of faunal movements for crossing safely the road.
