1同地共栖四种蝙蝠食性和回声定位信号的差异及其生态位分化显示文摘本研究于 2 0 0 2年 5月初至 2 0 0 3年 9月中旬在北京房山区霞云岭四合村蝙蝠洞进行 ,分析了共栖同一山洞四种蝙蝠的形态特征、食性和回声定位信号。大足鼠耳蝠食谱中以宽鳍等三种鱼为主 (体积百分比为5 3% ) ,回声定位主频 4 1 87± 1 0 7kHz;马铁菊头蝠主要掠捕鳞翅目昆虫 (73% ) ,恒频叫声主频 74 70± 0 13kHz ;中华鼠耳蝠以近地面或在地表活动的鞘翅目昆虫步甲类和埋葬甲类为主要食物 (6 5 4 % ) ,声脉冲主频较低 35 73± 0 92kHz;白腹管鼻蝠捕食花萤总科和瓢虫科等鞘翅目昆虫 (90 % ) ,回声定位信号主频为 5 9 4 7±1 5 0kHz。结果证实同地共栖四种蝙蝠种属特异的回声定位叫声和形态结构的差异 ,以及不同的捕食生境和捕食策略 。马杰 Walter METZNER 梁冰 张礼标 张劲硕 张树义 沈钧贤 2004动物学报2004,50,2:15
2Vocalization during copulation behavior in greater horseshoe bats,Rhinolophus ferrumequinum显示文摘Vocal communication plays an important role for individual recognition and male-female interaction during mating in greater horseshoe bats,especially in respect to mate fidelity,which ensures that the bats can maintain a stable social organization.Few studies,however,have addressed the calling behavior during copulating in bats.Here,we initially report the copulation vocalizations and behaviors of both male and female greater horseshoe bats.During copulation,the male assumed a dorsal position and arched his back,arming around the female using his feet and thumbs.The male repeatedly produced very short constant frequency(SCF) syllables with high intensity and repetition rate(male 1:16.48±4.8 ms,male 2:17.79±4.03 ms) when he tried to insert the penis into the female,and then long syllables(male 1:42.08±12.67 ms,male 2:43.02±11.44 ms) after penile insertion.The female bats sometime refused the male bats in the early phase of copulations as emitting noise bursts and broad-band vocalizations,but kept silence during actual copulation.We also found that the SCF copulation calls of one male remained stable peak frequencies on different copulation days although its echolocation call frequency varied each day.Moreover,different male individuals maintained their own 'private frequency' in the SCF copulation calls.Therefore,we predicted that the SCF copulation calls may serve as an indicator for female greater horseshoe bats to recognize the mating males in order to maintain mate fidelity because horseshoe bats exhibit sexual segregation before mating.Our results stipulate further studies on mating system and copulation strategies in polygynous bats.Such work may also aid in promoting the preservation of greater horseshoe bats.LIU Ying METZNER Walter FENG Jiang 2013Chinese Science Bulletin2013,58,17:4
