Diversity assessement of chiroptera at Lata Bijih and Lata Janggut by using mist netting technique.

Previously, there was no data on bats diversity assessment at Lata Bijih and Lata Janggut. This research was mainly conducted to assess the diversity of bats at the selected study areas. 10 sets of mist net were deployed on each site for a week. Selected point of deployment had been choosing according to its probability of getting good sampling results. All nets were daily changed its coordinate to increase sampling effort. A total of 34 individuals of bats had been recorded from 13 different species. The overall result shows the diversity at Lata Bijih is higher (0.574 index of species evenness) than Lata Janggut (0.457 index of species evenness). Rousettus leschenaulti had been recorded as a new record of bat species at Lata Janggut. Factors that influenced the sampling result have been discussed to improve the next research. All the samples were properly preserved in containers by adding 70% of alcohol solution. The data was interpreted by rarefaction curve and diversity indexes (species richness, species evenness, Shannon-wiener index) while species accumulative curve was constructed to show the effectiveness of sampling period towards sampling results.
