Trophic ecology and foraging behavior of Tropidurus hispidus and Tropidurus semitaeniatus (Squamata, Tropiduridae) in a caatinga area of northeastern Brazil.

Ecologia trófica e comportamanto de forrageamento de Tropidurus hispidus e Tropidurus semitaeniatus (Squamata, Tropiduridae) em uma área de caatinga do nordeste do Brasil. (Portuguese)

The article discusses findings of a study which determined the foraging behavior and diet composition of the Tropidus hispidus (T. hispidus) and T. semitaeniatus lizards found in Caatinga, Brazil. It describes the climatic conditions and trophic ecology of the Serido Ecological Station where the species was studied. Researchers used the Mann-Whitney U test for determining the seasonal diets and mean size of food ingested by the male and female species, while foraging intensity was observed based on number of moves, time spent stationary, and number of attacks on prey items.
