The goal of this project is to study the shrew communities by pitfall trapping at different elevation and habitat types, including the composition and abundance of shrews at different sampling sites, their morphology, diets and microhabitat use, in relation to local terrestrial invertebrate fauna and microhabitat characteristics, as well as the genetic variation of shrews at these sites, so that the morphology, diet and habitat requirement of different shrews, and the effect of body size, habitat and food competition on the structure of shrew communities can be examined. A total of 42 shrew individuals, including 7 Crocidura tadae, 8 Crocidura sp., 7 Crocidura attenuata, 20 Soriculus fumidus, were trapped at 14 sampling plots over 848 trapping night. Microhabitat analysis showed that microhabitat use of these species are all relevant to litter-soil humidity. In addition, Crocidura tadae and Crocidura sp. were caught more often in microhabitat with greater litter-soil depth and understory coverage; Soriculus fumidus were also caught more often in microhabitat with higher understory.
