中国特有种大卫鼠耳蝠回声定位声波、翼型特征及夏季食性分析
Echolocation calls, wing shape and summer diet of the Endemic Chinese bat, Myotis davidii
本文分析了中国特有种大卫鼠耳蝠（Myotis davidii）的回声定位声波、翼型特征和夏季食性。结果表明，大卫鼠耳蝠回声定位声波主频为60.4 ± 10.03 kHz （Mean ± SD），带宽为54.69 ± 8.53 kHz，能率环为7.37 ± 3.54 %；翼展比为6.15 ± 0.77，翼载为5.32 ± 0.92 N / m2，翼尖指数为2.16 ± 0.78；夏季食物主要以鞘翅目（57.70 %，体积百分比）和双翅目（36.01%）为主。根据其回声定位声波、翼型特征及食性结果，推测大卫鼠耳蝠主要在相对复杂的森林生境捕食，建议加大对当地森林的保护力度。
he echolocation calls, wing shape and summer diet of an endemic Chinese bat, Myotis davidii were analyzed in this paper. The results indicated that the peak frequency, bandwidth and duty cycle of echolocation calls in M. davidii is 60.4 ± 10.03 kHz (Mean ± SD), 54.69 ± 8.53 kHz and 7.37 ± 3.54 %, respectively. Aspect ratio, wing loading and tip shape index is 6.15 ± 0.77, 5.13 ± 0.64 N / m2 and 2.16 ± 0.78, respectively. Fecal analysis revealed that the summer diet of Myotis davidii is mainly consisted of Coleoptera (57.70 %, volume percent) and Diptera (36.01 %) insects. Based on the analysis of echolocation calls, wing shape and summer diet, we confer that Myotis davidii mainly probably forage in complex forest habitat. So we proposed to protect the local forest.
