Selection and use of calling site by Boana leptolineata and Phyllomedusa distincta during the reproductive season

ABSTRACT Climatic conditions and microhabitat characteristics, such as the substrate type of vegetation, influence choice male anurans for calling sites that optimize their reproductive success. We evaluated structure selection vocalization 17 individuals Phyllomedusa distincta Lutz, 1950 25 Boana leptolineata (Braun & Braun, 1977), in a subtropical forest southern Brazil. measure height perch, distance between perch edge body water quadrants used by individuals. The same attributes were measured available (but not used) classified microhabitats visual estimate, assigning percentages coverage each quadrant herbaceous, shrub, tree wetland vegetation. observed both species selected microhabitat, since characteristics occupied different from those available. was more associated with heterogeneous microhabitats, while B. occurred environments greater strata. Additionally, we shrubs frequently site. these must be strategies to use habitat, based on morphological behavioral species. Finally, it is possible infer differences can facilitate coexistence context heterogeneity environment.
