The role of ultrasonic bat detectors in improving inventory and monitoring surveys in Vietnamese karst bat assemblages

Bats account for 30% of mammal diversity in SE Asia and are potential bioindicators of wider biodiversity impacts resulting from habitat loss and climate change. As existing sampling techniques in the region typically fail to record bats that habitually fly in open areas and at higher altitudes, current inventory efforts are less than comprehensive. Acoustic sampling with bat detectors may help to overcome these limitations for insectivorous bats, but has yet to be tested in mainland SE Asia. To do so, we sampled bats while simultaneously recording the echolocation calls of insectivorous species commuting and foraging in a variety of karst habitats in north Vietnam. Monitoring of cave-dwelling bats was also undertaken. Discriminant function analysis of 367 echolocation calls produced by 30 insectivorous species showed that acoustic identification was feasible by correctly classifying 89. 1% of calls. In all habitats, acoustic sampling and capture methods recorded significantly more species each night than capture methods alone. Capture methods consequently failed to record 29% （ten spp. of aerial insectivores） of the bat fauna in commuting and foraging habitats and 11% （two spp. ） of that in our cave sample. Only four of these species were subsequently captured following significantly greater sampling effort. This strongly suggests that acoustic methods are indispensable for maximizing bat inventory completeness in SE Asia. As accurate inventories and monitoring are essential for effective species conservation, we recommend the inclusion of acoustic sampling in future studies of bat assemblages across the region [ Current Zoology 55 （5）： 327 - 341, 2009].

Distribution and ultrastructure of Merkel cell of the fishing bat (Myotis ricketti)

Science China(Life Sciences) 2009年第9期52卷 802-806页

作者： racey paul School of Biological Sciences University of Aberdeen

The distribution and ultrastructure of Merkel cells were described in detail in piscivorous bats through immunohistochemistry and transmission electron microscopy techniques. The findings indicated that Merkel cells are commonly found in raised-domes,hair follicles and in the basal epidermis of the skin from their back,abdomen,intercrural membranes,wing membranes and footpads. However,the density of Merkel cells is significantly higher in the footpad than in other places. These results suggested that there may be a link between Merkel cells and tactile sense,and also might imply that raised-domes with air-flow sensitive hairs played an important role in adjusting flying gestures by monitoring the air flow around the body. The ultrastructure of Merkel cells is similar to other vertebrates except having more intermediate filaments and larger granules.

Global biodiversity is currently in the midst of the sixth mass extinction,and countless species and their key ecosystem services are threatened across different habitats(Vos et al.2015).Constructive actions to address the negative impacts of changing conditions require rigorous biodiversity data integration and synthesis to inform effective policy-making decisions(Heberling et al.2021).Care is needed to ensure objectivity and remove biases in analyses to avoid generating misleading ***,Ramírez-Fráncel et al.(2022)published a review offering an update on the vital ecosystem services of bats on a global *** applaud the authors for their attempt to conduct an extremely challenging large-scale analysis in major areas of bat ecosystem services.

本文通过免疫组织化学与透射电子显微镜技术对食鱼蝙蝠Merkel细胞的分布及超微结构进行了详尽的研究.研究表明,Merkel细胞广泛存在于食鱼蝙蝠背部、腹部、股间膜、脚掌、翼膜皮肤的凸起、毛囊及表皮的基层.脚掌Merkel细胞的密度显著多于其他部位.这些结果意味着Merkel细胞可能与触觉有关:凸起物毛发对空气流动敏感,它可能通过感知身体周围空气的流动来调节飞行过程中的姿势.超微结构表明,与其他脊椎动物相比,食鱼蝙蝠的Merkel细胞含有较多的中间纤维及较大的内含物颗粒.
