Comportamentos territoriais de Tropidurus semitaeniatus (Spix, 1825) (Sauria, Tropiduridae) em uma área de caatinga do Sertão Paraibano.

Abstract

Lizards reach different temperatures for tangible physiological and behavioral reasons that are directly related to the availability of thermal resources of the environment in time and space. The territorial behavior occurs more intensely in the reproductive period and form of defense consisting of displays, fights and chases, vigorous fighting may occur. T. semitaeniatus heliothermic is a lizard that lives in open areas, one of the few species of reptiles that are commonly studied within the environment of Caatinga in northeastern Brazil. This study aimed to analyze the territorial behavior, thermal, foraging and reproductive behaviors made possible by T. semitaeniatus Site in Angola, São Mamede, Paraíba. 34 collections were made during the eighteen (18) months of research, were sighted 267 T. semitaeniatus and 33 of these were sighted were collected for morphometric analysis. The mean body temperature was (32.73 ° C) and for males (37.13 ° C) for females showing similarity to other species of the genus thereby justifying that the body temperature is influenced by thermal sources microhabitat (temperature air and substrate) homogeneously. Your hourly activity remained constant throughout the day and the species used microhabitats with little nearby vegetation of rocks used as habitat for foraging and termorregular, especially during the hottest times of the day observed during data collection.
