Paper Title
Salticidae Species Diversity in Selected Caves of Agusan Del Sur, Philippines

Abstract
Caves are some of the least explored ecosystems in the world. This study aimed to determine the species diversity and zonal distribution of Salticidae or jumping spiders in caves. Six caves in Agusan del Sur were surveyed where four zones were established per cave. Eighteen species of jumping spiders were collected from six caves. Four spider species are suspected novel species. Cave 4 had the highest species diversity (H�=2.197) and the highest species richness (S=9). Results showed that salticids of the same species were found in only one or two caves. Thirteen individuals were observed in the entrance zone of the cave while no salticid was observed in the outside zone. It was found that most salticids kept to a preferred zone in the cave. The species diversity differed in each cave, ranging from low to high indicating that each cave is a singularly unique ecosystem.
