Diversidad de anfibios anuros del Parque Nacional El Palmar (Provincia de Entre Ríos, Argentina)

el palmar national park (npep) is an important protected area in the eastern of entre rios province, argentina. it was created for preserving one of the last fragments of yatay palm (butia yatay). this study examines the biodiversity of the community of anurans that inhabit three types of environments of the park, the grassland, the straw zone and the gallery forest. sampling was conducted between the spring-summer 2008 and 2009. there were found 16 species of amphibians for npep, belonging to 6 families and 9 genera. among the types of environments, the straw zone showed the highest diversity and species richness. the relative abundances of the species were equitative in all three environments and there were significant differences in species composition among them being the grassland and pasture the most similar. this work is a significant contribution to the knowledge of the npep herpetofauna and a basis for future studies of natural history of amphibians. this also provides a tool for this protected area management and conservation.
