Dieta, forrageamento e ecologia reprodutiva de Tropidurus hispidus e Tropidurus semitaeniatus (Squamata, tropiduridae) de ambientes rochosos na Região de patos, Paraíba.

Abstract

The Caatinga is not a homogeneous biome and without distinctive wildlife, as until recently was admitted.; however, there still many studies to will be realized to understand the real dynamics o f this biome and use any kind o f strategies to preservate the speciess. Particularly characteristics like type o f soil, seasonal and undefinied pluviometric period and proper vegetation promote higher diversification o f reptiles, including lizards. The lizards are excellent models to study several aspects o f ecology and natural history, because are considered common and abundant in all places o f ocurrence.The genus Tropidurus present mainly lizards in open formations, heliophylus and generalists based on diet. Tropidurus hispidus show geographic distribution in all South portion o f american continent and in Caatinga biome is founded in sympatry with Tropidurus semitaeniatus, an endemic lizard o f this biome. Studies on the ecology o f lizards in the Caatinga has focused on factors that influence the life history of these animais and the developed strategies and adaptations to survive the determinants taxes to the inhabitants o f this biome.
