Abstract:
The Caatinga is highly heterogeneous, with many endemic species found in their regions. Much of the frogs in this area is commonly found in many open environments. In this study both the diversity and the temporal occurrence of frogs were determined to Bela Vista Lagoon, located in the municipality of Cuité, Paraíba. 4 áreas were marked for sampling, which are traversed by walking slowly. The naturalistic observations were conducted from May 2012 until April 2013. Search methods visual and auditory were used simultaneously to capture and frequency of species. We found six frog species belonging to 4 genera, distributed in three families: Bufonidae (2 species), Hylidae (2 species) and Leptodactylidae (2 species). Site 1 showed a wealth of 3 species, other areas have a wealth equivalent of 5 species each. The anurofauna recorded showed a high plasticity in the use of their habitats, the same breadth of occupation did not occur to vocalizations sites, found a high specification as their behavioral strategies. The nonparametric estimators, calculated for the 36 surveys of the lagoon Bela Vista, not reached its asymptote, but Bootstrap model tended to stabilize. Among the four areas sampled area 2 showed the most diversity, areas 3:04 showed the lowest diversity, this fact being related to high dominance of species Rinnella jimi. Regarding temporal distribution, just sort Scinix x-signatus was seen in the rainy season the other species were not influenced with the seasonality of the region, is showing annual species. The frogs tend to vary their temporal and spatial distribution of the parti habitat which they occupy.
