Previous issue date: 2008-08-28 / Tropidurus semitaeniatus and Tropidurus hispidus are lizard species that are widely distributed in Brazil. The former is endemic to the Caatingas, where they live in syntopy with
the latter, which is distributed in other ecosystems and biomes. In this work, diet was evaluated including seasonal variations as well as foraging behavior, to determine the
importance of these factors in the structure of these populations and the coexistence of these species in syntopy. No significant difference was found in diet composition between the two species, although T. hispidus feed on larger preys than do T. semitaeniatus; this fact, along
with the different foraging behavior in the rainy season, are ecological factors that contribute to the syntopic coexistence of these species in the Caatinga area studied / Tropidurus semitaeniatus e Tropidurus hispidus s?o esp?cies de lagartos que t?m ampla distribui??o no Brasil, sendo que a primeira ? reconhecida como end?mica das Caatingas,
onde vive em sintopia com a segunda, que se distribui em outros ecossistemas e biomas. Neste trabalho, avaliou-se a dieta incluindo varia??es sazonais e o comportamento de
forrageio, para averiguar a import?ncia de tais fatores na estrutura dessas popula??es e coexist?ncia dessas esp?cies em sintopia. N?o se constatou diferen?a significativa na
composi??o da dieta das duas esp?cies, embora T. hispidus se alimente de presas maiores do que T. semitaeniatus; este fato, aliado ? diferen?a no comportamento de forrageio na esta??o chuvosa, s?o fatores ecol?gicos que contribuem para a coexist?ncia sint?pica dessas esp?cies na ?rea de Caatinga estudada
