Habitats tend to be selected by individuals of different species in order to increase the fitness according to multiple ecology and behaviors factors, such as environment structure, foraging cost, competition and dispersion. Understanding of the environmental features that favors the occurrence of certain species in detriment of others species is important because it generates basic information for the comprehension of the patterns of distribution and abundance of populations. Thereby, the major aims of this study were evaluate the patterns of spatial distribution of three species of Pseudopaludicola, and to verify what environmental variables best explains the species occurrence and abundance. Following these objectives, will be characterized and sampled at least 40 water bodies in northwest São Paulo. The Pseudopaludicola species occurrence will be verified and it will be auditorily estimated the abundance of males in reproductive activity. The water bodies will be characterized according to landscape features (five variables), structural features (13 variables), physico-chemical properties of water (five variables). The influence of each feature of the three set of variables in Pseudopaludicola specie's spatial distribution will be evaluate using the Generalized Linear Model. After obtaining the best predictive model of the specie's abundance distribution, the influence of each variable existent in the model will be evaluated using the Hierarchical Partitioning analysis.
