| 中文摘要: |
| 于湖南省永州市铜岩洞采集到14只蝙蝠,经鉴定为大足鼠耳蝠(Myotis ricketti),为湖南省翼手目新纪录。本文报道了该物种体型和头骨特征,并与浙江和安徽样本进行比较。大足鼠耳蝠发出典型的下扫调频声波,其低峰频、短时程的声波特征以及强壮的后足和锋利的爪等形态特征与其在水面"拖网式(trawling)"捕食鱼类的捕食行为密切相关。 |
| 英文摘要: |
| Fourteen bats were captured at the Tongan Cave in Yongzhou of Hunan Province and identified as Myotis ricketti which is a new record of the Chiroptera in Hunan Province. The morphological measurements and skull characteristics were reported and compared to the same specimens in Zhejiang and Anhui Province. The species produces short echolocation calls with downward frequency-modulated(FM) components and low peak frequency. The special echolocation calls and morphology such as strong hind foot and sharp claws contribute M.ricketti to trawl fish over the water surface. |
