ResumoEstradas causam diversos impactos aos ecossistemas, incluindo perda e fragmentação de hábitat, alteração da paisagem natural e morte de animais, sendo que pouco se sabe sobre o impacto destas mortes sobre as populações. A fauna de serpentes do Estado de Santa Catarina é a menos estudada do Sul do Brasil, não havendo estudos abordando serpentes atropeladas. Neste trabalho apresentamos dados sobre serpentes encontradas mortas em diversas estradas do Estado entre os anos de 2003 e 2008. Foram registrados 165 exemplares pertencentes a 38 espécies que correspondem a 50% das serpentes com ocorrência esperada para o Estado de Santa Catarina. As quatro espécies mais freqüentes foram Philodryas patagoniensis (N= 22; 13,33%), Liophis miliaris (n = 21; 12,72%), P. aestiva (n = 13; 7,87%) e Bothrops jararaca (n = 12; 7,27%), que somadas representam cerca de 41% das serpentes encontradas mortas. Amplia-se ao sul a distribuição de Imantodes cenchoa em cerca de 60km.

AbstractSnakes killed on the roads in the state of Santa Catarina, southern Brazil. Roads cause diverse impacts to ecosystems, including habitat loss and fragmentation, alteration of the natural landscape and death of animals. However, little is known about the impact of this mortality on the animal populations. The snake fauna of the state of Santa Catarina is the least studied of southern Brazil. In this work we present data on 165 snakes of 38 species found dead on the roads of the state between 2003 and 2008, which corresponds to 50% of the snake species in relation to the expected occurrence for the state of Santa Catarina. The four most frequent species were Philodryas patagoniensis (n = 22; 13.33%), Liophis miliaris (n = 21; 12.72%), P. aestiva (n = 13; 7.87%) and Bothrops jararaca (n = 12; 7.27%), which represent together about 41% of the snakes found dead on the roads. We extend the known distribution of Imantodes cenchoa by about 60km southward.
A new record of the Gymnophtalmid lizard Ecpleopus gaudichaudi is presented for the state of Santa Catarina, extending its distribution about 50 km southeastward. We also briefly discuss the species nomenclature.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
