Pengaruh fisik goa terhadap struktur komunitas kelelawar pada beberapa goa karst di Gombong kabupaten Kebumen Jawa Tengah

Abstract

Research on the influence of physical environment to bat community structure in various cave at Gombong Karst Kebumen Central Java was conducted on September 2008 to March 2009. This research has been done at 12 caves. Map of bat's roost in each cave were produce by forward method (Hikespi, 1988). Bats were collected using mist net, harp net and stalk net. Fifteen species of bat were collected from this research, which are E. spelaea, R. amplexicaudatus, C. brachiotis, C. horsfieldii, H. sorenseni, H. diadema, H. bicolor, H. ater, H. cf. ater, C. plicata, H. larvatus, M. australis, M. screinbersii, R. affinis and R. borneensis, Redundance analysis (RDA) and spearman correlation analysis showed that length, height and width of cave's room correlated with bat community structure. However, number of cave entrance and cave ventilation did not correlate with bat community structure.
