北京宽耳蝠河北新纪录及其声音和食性初步研究
New record of Barbastella beijingensis in Hebei Province and preliminary studies on its acoustic and dietary characteristics
摘要
Abstract
The Beijing Barbastelle(Barbastella beijingensis)is endemic to China and has limited information on its calls,diet and distribution.In July 2023,five Barbastelle bats were captured in a mine cave in Suanzaoping Village,Hou-jiazhuang Town,Xingtai City,Hebei Province(37°22′15.59″N,114°02′16.8″E,727 m elevation).We collected the bats'feces,echolocation calls,distress calls,and morphological data.These individuals are medium-sized,with a forearm length of(43.8±1.6)mm.There is a connection between the ears at the forehead,the outer ear contour is nearly square and has a distinct transverse ridge,and the middle outer edge has a smaller ear protrusion.The skulls are narrow and long,with a total length of 15.50 mm to 16.02 mm,a smooth skull top,and a larger interorbital distance.Based on ex-ternal morphology,cranial parameters,and molecular phylogenetic analysis(Cyt b and ND1 genes),the captured individ-uals were identified as B.beijingensis.The echolocation calls of the B.beijingensis are frequency-modulated,with the highest energy at the second harmonic,a peak frequency of(70.90±3.75)kHz,a bandwidth of(26.17±4.96)kHz,and a pulse duration of(2.89±1.13)ms.The distress calls were divided into three simple syllables(long downward fre-quency modulation,short downward frequency modulation,and wrinkled frequency modulation)and one compound syl-lable(noise-wrinkled frequency modulation).The diet mainly consists of insects from the order Lepidoptera(relative read abundance 99.7％),as well as a small amount of insects from the orders Blattodea,Diptera,and Hymenoptera.This discovery represents a new bat species record for Hebei Province,and it enriches the acoustic and dietary data of the B.beijingensis,providing basic data for subsequent in-depth research.关键词
