RESUMO
Predation activity of Tropidurus hispidus (Sauria, Tropiduridae) in Nisia floresta- RN, Brazil. Tropidurus sp is a generalist predator who uses both sit and wait foraging strategy or sedentary strategy to catch prey. In this study we noticed thepredation activity of Tropidurus hispidus in a rain forest area in Nísia Floresta from december 6th to 10th, 2004. The scan sampling and ad libitum observation methods were used to collect data. Our search showed that T. hispidus presented a sedentary predation behavior. There was significant difference (p 0,001) for couple analysed area in predation. We noticed a bimodal occurrence in predation. This data were related with the sun incidence. This suggests that the temperature and the catch prey type, in association, can determine its foraging behaviors temporal profile.
