Composición y riqueza de anfibios y sus relaciones con las características de los sitios de reproducción en un sector de la Selva Atlántica de Misiones, Argentina. Cuad. herpetol.

Atlantic forest harbors a large number of endemic amphibian's species. At present only 7.5 % of the Atlantic Forest original surface remains. In this study we compare frog's species richness and assemblage composition between different types of reproductive habitats in a sector of the Atlantic Forest of Argentina. Surveys were made during four months in two consecutive years. Four reproductive habitats were surveyed: temporary ponds, pig wallows, temporary streams and permanent streams. Frogs species richness and composition and environmental descriptors were recorded in these habitats. Temporary ponds have the greatest richness. Anuran abundance shows associations with vegetation in the bodies of water. The results suggest that different types of wetlands exert differential pressures (e.g. predation, hidroperiod) on amphibian assemblages. Finally, we highlight the importance of small ponds and vegetation heterogeneity for anuran assemblages of the Atlantic Forest of Argentina.
