SUMMARY:

Autoecology is the branch of ecology responsible for the study of the relationships of species with the environment in which they live. Autoecological aspects, such as feeding, use of microhabitat, reproductive biology, morphology and parasitology, are of fundamental importance for understanding the natural history and ecology of the species. In addition, such aspects contribute to environmental and species management and conservation strategies. Research in this area has been developed with different types of animals, including lizards. Therefore, considering that the data in the literature on populations of G. geckoides, in the state of Pernambuco, remain poorly, or not studied, in addition to revealing obsolete data on their autoecological aspects, the present work aimed to elaborate an updated description, in addition to being more accurate. , on autoecological aspects of this lizard, in a remnant of Caatinga, in the state of Pernambuco. In total, 203 individuals were analyzed, 68 females, 98 males and 31 juveniles, plus 6 animals that could not be identified by gender. The data obtained allow us to classify G. geckoides as a generalist lizard, whose diet varies according to the availability of the environment, presenting variations in the number of ingested prey, as well as the ingestion of energetically advantageous prey during rainy periods. The micro-habitat also varies according to the environment, indicating a preference for native vegetation, when present. The parasite-host relationship revealed a positive and significant relationship of the helminths found with morphology and seasonality, as well as the types of prey ingested, such as coleoptera. Finally, the energy reserve factors, as well as the modification of reproductive cells, indicate that this species presents continuous and acyclic reproduction, being highly correlated with the rainy season, in which a higher frequency of females carrying eggs in the oviduct and ovaries in the vitellogenic stage could be found. . Therefore, energy reserves are used on a larger scale by this group as a function of pregnancy and ovary maturation.
