贵州省松桃县东部地区翼手目物种多样性

2008年7月至2009年2月,对贵州省松桃县东部地区的14个镇(乡)47洞穴翼手目的种类、数量、分布及生境进行调查研究。通过标本的采集、鉴定,确定该地区共有翼手目动物3科14种,其中2种为待定种;爪哇伏翼(Pipistrellus javanicus)、棒茎伏翼(P.paterculus)、单角菊头蝠(Rhinolophusmonoceros)3种在贵州省首次发现,其中单角菊头蝠是在中国大陆首次发现。另外,还对该地区蝙蝠的冬眠行为、对冬眠地的选择以及栖息环境的受胁现状进行了初步调查,发现不同种类蝙蝠的冬眠行为是不一样的;同时发现,洞外捕食生境的不同会造成洞穴内分布翼手目种类的不同。

The Chiroptera Species Diversity in Eastern of Songtao, Guizhou Province

From July 2008 to February 2009,we conducted a survey on the bats species diversity in 47 caves at 14 townships in eastern of Songtao County,Guizhou Province. We found it showed 14 species belonging to 3 families,one of them need to identify further. Three species, Pipistrellus javanicus, P. paterculus, and Rhinolophus monoceros are the new records to Guizhou Province,and R. monoceros was found first time in the mainland of China. We also collected information on the hibernation behavior and habitat selection of bats,as well as the threats to their habitat. The hibernation behavior was obvious differences between different species of bat,and the species variation between caves might be indicated by the habitat type difference out of the cave.
