Abstract:
A study on understory bat species diversity and relative abundance by using mist nets was carried out in Kayan Mentarang National Park, East Kalimantan, Indonesia in 2003. A total of 11 species of bats from three families and nine genera were captured using mist nets during 16 sampling nights. This represents approximately 12% of the total chiropteran fauna known to occur in Borneo. Capture rates were 72 bats per 100 net night. A total of seven species of pteropodid bat species, accounting for 91.6% of the total capture,were recorded in the forest understory. The most frequently caught species was Cynopterus brachyotis followed by Aethalops alecto, which comprised 58.9% and 16% of the total captures, respectively. A low relative abundance was observed for four entomophagous species, which represented by seven or less captures. The daily species accumulation curve showed no signs of leveling out, which may be confounded by the heterogeneous habitats between sites, suggesting that additional effort might yieldmore species of bats. As this study was concentrated mainly in the understory, additional trapping efforts and utilization of ultrasonic bat detectors and harp traps in the forest canopy and sub-canopy will be necessary to add more species to our recent findings.
