Abstract

This study focused on spiders associated with rivers and streams, their age structure and guild composition, and the relationship of study site elevation on their diversity. The survey was conducted in two sites: Molawin Creek in UPLB and the river along the secondary forest of the Science and Technology Campus of DLSU (STC-DLSU). Orsinome vethi (Hasselt) (Tetragnathidae) dominated the samples (154 individuals) for Molawin Creek and STC-DLSU rivers combined. Other tetragnathid species were found to be the most dominat in the entire collection period. It was noted that female adults and sexually-undetermined immatures dominated the Molawin Creek samples. On the other hand, for STC-DLSU river samples, only the sexually-undetermined immatures were noticeable. The spiders collected were further classified into six different guilds. It was confirmed that species diversity increases with elevation.
