Diversidade de lagartos (Squamata) em uma floresta estacional semidecidual da Serra de Santa Catarina, Sertão Paraibano.

Abstract

The diversity of lizards was studied in the Serra de Santa Catarina (SSC), located in the municipality of São José da Lagoa Tapada, Paraíba, between the months of July 2012 and January 2014. Five (5) environments with different vegetation types were chosen in this study area with the aim of analyzing the similarity of species presented in them, and show what factors are responsible for its occurrence. With this aim, 30 environmental variables were observed. 15 species of lizards were found and 13 species were captured (except Iguana iguana and Vanzosaura rubricauda) using pitfall traps, glue traps and active search limited by time and chance encounter. The 15 species found in the SSC belong to families Anguidae, Gekkonidae, Gymnophtalmidae, Iguanidae, Phyllodactylidae, Sphaerodactylidae, Teiidae and Tropiduridae. From the 150 individuals captured, the most abundant species was Micrablepharus maximiliani (33), which represented 22% of all individuals collected, followed by Colobosauroides cearensis (31), being this the first record of its occurrence beyond their typical locality (state of Ceará). There was greater similarity between the environments I and III when comparing the type of environment versus environmental variables (according to the Bray-Curtis coefficient, based on abundance data) and environments III and IV (according to the Jaccard coefficient, based on the presence-absence of species). The type of environment versus species richness of environments I and III were also the most similar, totalizing nine (9) and eight (8) species presented, respectively. Beyond a survey of species and comparison between five (5) types of environments, from the environmental variables observed, this study also showed aspects of morphometry and folidose analysis of each species studied.
