摘要。研究了越南中部高原大叻高原林东省比杜普努伊巴国家公园（BNBNP）蝙蝠群落的物种多样性、季节性繁殖和回声定位模式。在26 994 m2雾网小时和3015 m2捕集器小时的努力下，共捕获了27种，211只。发现翼足类5种，食虫蝙蝠22种，分4科，其中包括越南地区有记录的种类和在越南罕见捕获的种类。目前已知BNBNP的蝙蝠物种丰富度为33种，其中包括先前研究中发现的6种。根据Simpson多样性逆指数，捕获的均匀度较低，反映了少数物种的高丰度，而许多物种仅被一两个个体记录。食虫蝙蝠在旱季后期怀孕，而在哺乳期发生的湿季不会怀孕，并且会捕获叛逆的幼崽。测定了19种食虫蝙蝠的回声定位叫声特征。呼叫模式与东南亚其他地方的一些文献报道一致，但并非全部。这表明东南亚蝙蝠的回声定位叫声是否存在隐种或地理和栖息地的差异，需要进一步研究。
Abstract. We determined species diversity, seasonal reproduction, and echolocation patterns in the bat community of Bidoup Nui Ba National Park (BNBNP), Lam Dong Province, on the Dalat Plateau of the Central Highlands of Vietnam. We documented 27 species with 211 individuals captured in 26 994 m2 mist-net-hours and 3015 m2 harp-trap-hours of effort. We found five species of pteropodids and 22 species of insectivorous bats in four families, including regional records and species seldom captured in Vietnam. Bat species richness at BNBNP is now known to be 33 species, including six found in a prior study. Based on the inverse Simpson Index of Diversity, evenness of captures was low, reflecting the high abundance of a few species with many species documented by just one or two individuals. Insectivorous bats were pregnant in the late dry season, but not during the wet season when lactation occurred and volant juveniles were captured. Echolocation call characteristics were determined for 19 species of insectivorous bats. Call patterns were consistent with some but not all reports in the literature from elsewhere in southeast Asia. This suggests the existence of cryptic species or geographic and habitat variability in echolocation calls of southeast Asian bats that requires further study.
