Composição da taxocenose de anuros do Horto Florestal Olho D'água da Bica - Cuité - PB.

Abstract

Knowledge about the ecological characteristics of populations of frogs present an important feature, since these populations have a high microenvironmental specificity and small capacity to adequate to anthropogenic interference making it extremely vulnerable to environmental changes . This work aims to characterize the composition of anuran assemblage of Olho D'água da Bica's Horto Forest as well as describe the microhabitats used by these animals in the study area and its distribution over the sampling months. The study was conducted in the Olho D'água da Bica Horto Forest (ODBHF), located near the campus of the Federal University of Campina Grande (UFCG) — Health and Education Center (HEC), in the city of Cuité - PB, located in the microregion of Western Curimataú of state of Paraíba. Collected data and observations were made monthly for four consecutive days during the night between the months of may 2012 to april 2013. The method employed for the collection was the one of active search in the sampled area. The area is composed of three environments: A permanent artificial small pond, an open area and a permanent soaked pond. They were made hiking while traveling around and margins of each area. The evidence material was deposited in the Zoology Curriculum Collection (ZCC). In the ODBHF were found l3 species of amphibians, belonging to 10 genera of 6 different families ( Hylidae , 6 species; Bufonidae , 2 species; Leptodactylidae , 2 species; Leiuperidae , l species; Pipidae , l species; Microhylidae, l species). The frogs were presented and distributed in 12 microhabitats, identified in the study area, such as water, grass, dry branches, lianas, wall, stones, puddle, fallen log. The microenvironments with higher presence of species were water (8 species), bare soil (7 species) and grass (6 species). The hylids had a higher plasticity of microhabitat use, occupying about 10 environments. It was found that the greater number of individuals took place in april 2013.
