Resumen
Descripción general del contenido del recurso.
This work was conducted in «La Quebrada» Reserve, a protected area that is a representative of the Sierras Chicas. The aim of the present study was to describe the composition and diversity of the herpetofaunal community, its seasonal changes, and to test the differences in composition among herpetofaunal assemblages in highland pastures, forest and stream borders. The relationship between abundance, diversity and climatic variables was also tested. One to three sampling lines with 15 pitfall traps 10 m apart from each other were set in each environment. The traps were monthly checked between February 1991 and May 1994. The total number of trapped animals was 147, distributed among 21 species: 8 amphibians (n= 114), 8 snakes and 5 lizards. Odontophrynus occidentalis and Hyla pulchella cordobae comprised 60% of the total abundance. H. p. cordobae was the only species found in all environments. The species with the highest abundance were Odontophrynus americanus and Leptodactylus gracilis in highland pastures, O. occidentalis and Mabuya dorsivittata in forest and O. occidentalis and H. p. cordobae in stream borders. Neither of the 3 studied environments showed differences in both species abundance and richness, but in each environment the herpetofaunal community had different structural and functional features. The highland pastures had the highest diversity (H´= 1,93) followed by forest (H´= 1,41) and stream borders (H´= 1,19). Abundance, richness and diversity of the herpetofaunal community as a whole were related directly with temperature and rainfall. Two different communities were detected, one related to the grassland habitat and the other to the forest-stream border unity. The high deforestation rates recorded in the area might modify the abundance relationships between species and the patterns of herpetofaunal diversity.
