Abstract

Richness, diversity and abundance of spider species associated with the highland savanna in Valle Nuevo National Park is recorded and compared between a wet and a dry season. Four plots of 20x20 m (two in each season) were established and five grids of 2x2 m were delimited within each plot. A total of 222 specimens belonging to 19 families, 23 genera and 35 species were collected. No significant difference was found between seasons for the Shannon index (P=0.86), Simpson index (P>0.99) and Pielou index (P=0.41). The Jaccard similarity index between seasons was 0.46. The highest quantity of estimated species was 46 (Chao 2) for the dry season and 39 (ACE) for the rainy season. In the rainy season, Salticidae was the most abundant family (21.54%) and Linyphiidae the most diverse (four species); Barronopsis barrowsi (Gerstch) was the most abundant species (18.96%). In the dry season, the family Anyphaenidae was the most diverse and abundant (four species and 44.31%) and Anyphaena pusilla Bryant the most abundant species (21.69%).
