Uso de recursos espaciais em taxocenose de girinos em uma área de mata atlântica no estado da Paraíba-Brasil

Abstract

The way in which species occupy the spatial resources available in the habitat reflects in how they interact in the community in which they are inserted, and may even reflect on the composition of species from a given place. Therefore, understanding this interaction and the distribution of the assemblage is highly relevant. Previous studies have pointed out several factors that influence and shape the distribution of tadpoles in their habitat, but there is no consensus on the factors that determine and shape such assemblage. Thus, this study aimed to analyze how tadpole species use the spatial resource in a fragment of Atlantic Rain Forest (RVS Mata do Buraquinho), verifying how they a re distributed through habitat and microhabitat and verifying what are the factors that are acting as modeling pressures on the assemblage. The efficiency of the sampling effort was verified through rarefaction curves based on individuals. We collected 126 2 individuals of 8 species. Assemblage was structured and the presence of macrophytes, body water area and turbidity index were the variables that most influenced the distribution of animals in the environment. The main factors that affect the distribution of the studied tadpoles can be altered by anthropic means, therefore, it is crucial to look out for lentic ecosystems present in forests so that the maintenance of amphibian assemblage is possible.
