Abstract

Tasikmalaya district has a large karst area with many potential caves. Up to the present, subterranean biodiversity in this karst area was still poorly understood. This project aimed to investigate the diversity and abundance of cave-dwelling insecta also abiotic parameters in three selected caves located in Tasikmalaya karst area. Insecta samplings were conducted in each cave zonation (entrance, twilight and dark zones) by hand collecting, pitfall traps, and Berlese extractors. Abiotic parameters including light intensity, air temperature, relative humidity (RH), soil temperature, soil moisture, and soil pH were also measured. In total 1142 individuals grouped into 9 orders, 19 families and 37 morphospecies were collected during the study. Richness and diversity indices were greater in entrance and twilight zones compared to dark zone, while evenness index was varying among communities. Camel cricket (Rhaphidophoridae) and Cockroach (Family: Blattidae and Blaberidae) were dominant in the dark zone. Abiotic parameters were varying within cave zonation. Light intensity and soil pH were higher in entrance and twilight zones compared to dark zone, otherwise air temperature, RH, soil temperature, and soil moisture were higher in the dark zone. Richness and diversity were positively correlated with light intensity and soil pH but negatively correlated with air temperature, RH, soil temperature and soil moisture.
