Abstract

Vanderhaege’s toad-headed turtle (Mesoclemmys vanderhaegei) natural history is poorly known. The goal of this study was to describe the population structure of a M. vanderhaegei population in a silvicultural system in Alto Paranapanema River Basin, in Southeastern Brazil. We captured 31 individuals in funnel traps from October 2010 to April 2011 in three ponds: Lagoa Suja (n=20); Lagoão (n=6) and Açude do Cerrado (n=5). The population size of Lagoa Suja has been estimated in 26 individuals (0.65 individual/ha; 492 g/ha). Sex ratio was approximately 1:1 (?:?). Approximately half of the total population (48%) had injuries. Females were larger than males, and the overall size of both sexes in the present study were greater when compared to other populations.
