采用PCR技术获得了翼手目(菊头蝠总科、蝙蝠科以及鞘尾蝠科)16种19个个体的核基因重组激活基因2(Recombination activating gene,RAG2)部分序列,长度为730～760 bp.结合从Genbank中提取的翼手目3科14个体的RAG2序列,通过构建贝叶斯(Bayesian inference,BI)和最大似然树对翼手目种属间的系统进化关系进行研究.研究表明:在菊头蝠总科中,菊头蝠科和蹄蝠科是两个独立的科,且在蹄蝠科中,大蹄蝠、中蹄蝠、普氏蹄蝠3种之间的亲缘关系非常近;蝙蝠科中的南蝠属与棕蝠属是姊妹群;长翼蝠亚科应提升为长翼蝠科.此外,鞘尾蝠科与犬吻蝠科形成姊妹群关系.     

贵州省四种蝙蝠携带病毒组

翼手目(Chiroptera)动物已被确认是人畜共患病毒的重要自然宿主。贵州省翼手目物种多样性资源丰富,包括了2亚目7科19属65种,但在其携带病毒方面的研究仍然不全面。本文基于病毒宏基因组学和s RNA病毒检测,对贵州省广泛分布的大蹄蝠(Hipposideriderosarmiger)、三叶蹄蝠(Aselliscus wheeleri)、贵州菊头蝠(Rhinolophus rex)和皮氏菊头蝠(R. pearsoni)携带的病毒进行注释及鉴定。通过分析得到所携带病毒的种类;并比较了贵州省与云南省和广西省3个地区翼手目携带病毒在种类上的差异。结果显示,在4种蝙蝠中检测出脊椎动物病毒、昆虫病毒、植物病毒、细菌病毒4大类,共计53科111属170余种病毒,其中具有公共卫生学意义病毒9科10属46种,如:人疱疹病毒1型病毒(Human herpesvirus 1)、戊型肝炎病毒(Hepatitis E virus)、人乳头瘤病毒16型(Human papillomavirustype16)等相关的病毒。贵州省与云南省和广西省3个地区的蝙蝠所携带病毒种类比较发现,只有腺病毒科(Adenoviridae)和逆转录病毒科(Retroviridae)均存在于3个省份的蝙蝠体内,说明病毒种类在不同地域分布的蝙蝠种类中存在较大的差异。贵州省分布的大蹄蝠、三叶蹄蝠、贵州菊头蝠和皮氏菊头蝠携带病毒的种类较多,其病毒种类在公共卫生学上具有一定的代表性,对开展贵州省分子流行病学调查具有重要价值。

2018年7月至2021年2月,采用栖息地调查法和网捕法对贵州洋溪省级自然保护区翼手目动物物种多样性及保护现状进行了调查。共记录到翼手目动物3科6属13种,包括蝙蝠科5种,菊头蝠科5种,蹄蝠科3种。按照中国动物地理区划,以东洋界种类为主,共有11种,另有2种为广布种。列入《中国生物多样性红色名录：哺乳动物》近危级（NT）7种、无危级（LC）物种6种;列入IUCN物种红色名录近危（NT）级1种,无危级（LC）12种。此次在洋溪自然保护区共调查了27个洞穴,其中20个洞穴有蝙蝠栖息。大蹄蝠（Hipposideros armiger）分布最广,在10个洞穴有分布;其次是皮氏菊头蝠（Rhinolophus pearsonii）,在8个洞穴发现;小菊头蝠（R. pusillus）在7个洞穴有分布。对蝙蝠栖息洞穴的干扰情况进行调查发现,超过一半（55%,n = 20）的洞穴存在人类干扰活动,如村民进洞游玩、在洞内饲养家畜、驱赶蝙蝠、进行祭祀活动以及破坏洞口等。建议对村民在洞内养殖家畜、游玩、驱赶蝙蝠等行为加以限制,并通过引导村民文明祭祀、对被封洞口进行疏通、对古老建筑进行修缮等方式,加强对该地区蝙蝠的保护。同时还建议对该保护区的蝙蝠及其栖息地进行长期监测。     

四川七种蝙蝠的核型

本报道了四川地区7种蝙蝠的核型。菊头蝠科2种,即角菊头蝠(Rhinolophus comutus)的核型为2n=62,FN=60;栗黄菊头蝠(R．ssinicus)的核型为2n=36,FN=60。蹄蝠科1种,即大蹄蝠(H．armiger)的核型为2n=32,FN=60。蝙蝠科3种,即伏翼(Pipistrellus abramns)的核型为2n=26,FN=44;南蝠(Iaio)的核型为2n=50,FN=48;山蝠(Nyctalus velutinus)的核型为2n=36,FN=50。犬吻蝠科的皱唇蝠(Tadarida teniotis)的核型为2n=48,FN=62。南蝠的核型为首次报道,但栗黄菊头蝠的核型2n=36与安徽张维道报道相同,而与印度和斯里兰卡同种R．rouxii的核型2n=56迥异。分布在中国的栗黄菊头蝠R．sinicus应为独立种而不是R．rouxii的中国亚种。另5种蝙蝠的核型与前人研究结论基本一致。     

蝙蝠和鲸都是种名吗

初中《动物学》课本在讲哺乳纲的翼手目和鲸目时,介绍了蝙蝠和鲸。我们查阅了《辞海》(生物分册)553页,书中写到:“蝙蝠,哺乳纲、翼手目动物的通称,是具有飞翔能力的哺乳动物……分大蝙蝠和小蝙蝠两大类。前者体型大,第一和第二指均有爪,以果实为食,如狐蝠、果蝠、犬蝠。后者体型较小,仅第一指具爪,种类较多,一般以昆虫为食,如菊头蝠、蹄蝠、伏翼(家蝠)、山蝠、大耳蝠等。可见,     

潇水河永州零陵段沿岸蝙蝠物种多样性调查

2011年5月—2013年8月对潇水河永州零陵段沿岸蝙蝠物种多样性进行了初步调查。共记录到蝙蝠8种,分属3科5属。从分布型看,东洋型种类占多数(62.5%);从种群数量看,东亚伏翼Pipistrellus abramus与大蹄蝠Hipposideros armiger占优势,斑蝠Scotomanes ornatus数量最为稀少。区域内蝙蝠喜栖于竹丛、树冠、岩壁、洞穴、民居与古建筑等处。上、下游所栖蝙蝠种类存在差异,但均喜好在水体与植被交接处活动而形成活动聚集地,且洞穴冬眠型蝙蝠的年活动周期较房屋冬眠型蝙蝠的短。调查结果增加了对潇水河沿岸蝙蝠生存现状的了解,可为进一步开展蝙蝠研究和保护提供参考。     

香港大蹄蝠出飞时间及其季节变化

于2014年5月至2015年4月,对香港低海拔栖息地的大蹄蝠夜晚出飞活动时间进行了研究。结果显示大蹄蝠出飞时间平均为日落后（14.6±6.1) min,出飞时间与民用曙暮光呈强正相关（r = 0.968, P < 0.0001）,而出飞结束时刻同样与民用曙暮光时间呈现显着相关(r = 0. 977, P < 0. 0001)。。在一年中较冷的12月和1月则没有蝙蝠出飞记录。大蹄蝠虽然在亚洲分布广泛,但是相对于温带地区的蝙蝠物种来说, 关于该物种的基础生态学研究较少。本文对大蹄蝠的季节性出飞行为所开展研究工作,以利有关长远保育的深入研究。

Acoustic identification of eight species of bat (mammalia: chiroptera) inhabiting forests of southern hokkaido, Japan: potential for conservation monitoring

Assessing the impact of forest management on bat communities requires a reliable method for measuring patterns of habitat use by individual species. A measure of activity can be obtained by monitoring echolocation calls, but identification of species is not always straightforward. We assess the feasibility of using analysis of time-expanded echolocation calls to identify free-flying bats in the Tomakomai Experimental Forest of Hokkaido University, Hokkaido, northern Japan. Echolocation calls of eight bat species were recorded in one or more of three conditions: from hand-released individuals, from bats flying in a confined space and from bats emerging from their roost. Sonograms of 171 calls from 8 bat species were analyzed. These calls could be categorized into 3 types according to their structure: FM/CF/FM type (Rhinolophus ferrumequinum), FM types (Murina leucogaster, Murina ussuriensis, Myotis macrodactylus and Myotis ikonnikovi) and FM/QCF types (Eptesicus nilssonii, Vespertilio superans and Nyctalus aviator). Sonograms of the calls of R. ferrumequinum could easily be distinguished from those of all other species by eye. For the remaining calls, seven parameters (measures of frequency, duration and inter-call interval) were examined using discriminant function analysis, and 92% of calls were correctly classified to species. For each species, at least 80% of calls were correctly classified. We conclude that analysis of echolocation calls is a viable method for distinguishing between species of bats in the Tomakomai Experimental Forest, and that this approach could be applied to examine species differences in patterns of habitat-use within the forest.     

菲菊头蝠回声定位声波频率的性二态有利于性别识别

许多动物的叫声频率呈现性二态现象。蝙蝠夜间活动,主要利用声音信号导航空间、追踪猎物、传递交流信息。本研究选择成体菲菊头蝠作为研究对象,检验回声定位声波频率性二态是否有利于性别识别。研究发现,菲菊头蝠回声定位声波频率参数具有显著性别差异。播放白噪音、雄性回声定位声波及雌性回声定位声波期间,实验个体的反应叫声数量依次递减。播放白噪音、雌性回声定位声波及雄性回声定位声波后,实验个体的反应叫声数量依次递增。白噪音诱导反应叫声强度高于回声定位声波诱导反应叫声强度。研究结果表明,菲菊头蝠回声定位声波的频率参数编码发声者性别信息,有利于种群内部的性别识别。本研究暗示,回声定位声波可能在蝙蝠配偶选择中扮演一定作用。     

Identification of sympatric bat species by the echolocation calls

One hundred and thirty-eight echolocation calls of 63 free-flying individuals of five bat species (Rhinolophus ferrumequinum,Myotis formosus,Myotis ikonnikovi,Myotis daubentoni and Murina leucogaster)were recorded (by ultrasonic bat detector (D980)) in Zhi'an village of Jilin Province,China.According to the frequency-time spectra,these calls were categorized into two types:FM/CF (constant frequency) / FM (R.ferrumequinum) and FM (frequency modulated)(M.formosus,M.ikonnikovi,M.daubentoni and M.leucogaster).Sonograms of the calls of R.ferrumequinum could easily be distinguished from those of the other four species.For the calls of the remaining four species,six echolocation call parameters,including starting frequency,ending frequency,peak frequency duration,longest inter-pulse interval and shortest inter-pulse interval,were examined by stepwise discriminant analysis.The results show that 84.1% of calls were correctly classified,which indicates that these parameters of echolocation calls play an important role in identifying bat species.These parameters can be used to test the accuracy of general predictions based on bats' morphology in the same forest and can provide essential information for assessing patterns of bat habitat use.     

蝙蝠回声定位声波的可塑性及其生态适应

蝙蝠通过调节回声定位声波特征来满足自身的感官需求,表现出回声定位声波的可塑性及其对生态环境与需求的适应。声波频率、强度、脉冲持续时间和间隔时间等特征与蝙蝠所处的生态位密切相关,声波可塑性在蝙蝠进化过程中起着至关重要的作用。本文结合马铁菊头蝠(Rhinolophus ferrumequinum)和大趾鼠耳蝠(Myotis macrodactylus)回声定位声波可塑性的研究,从回声定位声波的方向性、目标距离、环境复杂度和应对干扰4个方面总结了蝙蝠如何通过改变回声定位声波特征来满足自身在导航和捕捉猎物过程中的感官需求与生态适应,并阐述了回声定位声波可塑性的研究现状,为开展蝙蝠声学和行为学研究提供参考。     

菲菊头蝠不同地理种群回声定位声波差异及其影响因子

回声定位声波地理差异及其形成原因是蝙蝠生态学研究领域一个基本而关键的问题,对于探索物种生存机制、物种形成及其保护具有重要科学意义。本研究从较大地理尺度上(9个地理种群)研究了菲菊头蝠(Rhinolophus pusillus)回声定位声波结构的地理差异,并进一步探讨了影响回声定位声波地理种群差异的因素。结果表明,菲菊头蝠雌性的体型较雄性略大,其主频较高。不同地理种群之间回声定位声波差异明显,包括脉冲持续时间、脉冲间隔、主频以及带宽在不同的地理种群之间均表现出一定程度的差异。进一步分析发现,不同地理种群之间的雌性菲菊头蝠前臂长和体重均与主频呈较弱的负相关,降雨量与雌性的主频呈较强的正相关;而不同地理种群之间的雄性前臂长、体重和降雨量与回声定位声波参数均无相关性;此外,地理距离、温度、湿度均与雌雄回声定位声波参数无相关性。本研究结果表明,菲菊头蝠不同地理种群间的回声定位声波出现明显差异,其中,体型和降雨量为主要影响因子,说明蝙蝠回声定位叫声的进化主要受到了当地生境的影响,表现出动物对不同生境的适应性进化。     

Interspecific responses to distress calls in bats (Chiroptera: Vespertilionidae): a function for convergence in call design?

Distress calls were recorded from three sympatric species of pipistrelle bat (Pipistrellus nathusii, P. pipistrellus and P. pygmaeus) in England and Northern Ireland. At foraging sites, we conducted playback experiments, consisting of experimental distress call sequences from each species and control sequences of random noise and sound recorded with no bats present. We measured response by simultaneously recording ultrasound during playbacks and counting the echolocation pulses above a predetermined threshold which were then identified to species. All three species responded to each other's calls. The number of recorded echolocation pulses of all species increased eight-fold, on average, during the playback of distress call sequences compared with the playback of ultrasonic noise, and four-fold compared with the playback of silence. In a separate playback experiment, the number of echolocation pulses of P. pygmaeus increased 14-fold during the playback of distress calls of four endemic species of bat from Madagascar (Emballonura atrata, Myotis goudoti, Miniopterus majori and M. manavi) compared with the playback of silence. This increased response might have been caused by the high calling rates of the Malagasy species. Distress calls of P. nathusii, P. pipistrellus and P. pygmaeus were structurally convergent, consisting of a series of downward-sweeping, frequency-modulated elements of short duration and high intensity with a relatively strong harmonic content. Selection may favour convergence in the structure of distress calls among bat species, if attracting heterospecifics increases the chance of repelling predators by mobbing.     

在不同状态和生境复杂度中大蹄蝠回声定位叫声的可塑性

蝙蝠回声定位声波的可塑性对其适应不同状态、生境以及捕食和社会交流具有重要的作用。为进一步研究大蹄蝠的回声定位声波在不同状态和生境下的可塑性,通过室内行为实验,对大蹄蝠在4 种不同状态(室内飞行、静息、布袋内和手持)和4 种不同生境复杂度(室外、室内0 棵树、室内1 棵树、室内5 棵树)条件下飞行的回声定位声波特征进行研究。结果表明:大蹄蝠的回声定位声波为CF - FM 型,通常连续发出2 - 4 个脉冲组成一个脉冲组。对比大蹄蝠在4 种不同状态下的回声定位叫声发现,主频按静息、布袋内、手持、飞行的顺序依次降低,后端FM 频宽则按手持、布袋内、飞行和静息的顺序依次变短;而脉冲间隔和脉冲时程则均按静 息、飞行、布袋内、手持的顺序依次增加。对比大蹄蝠在4 种不同生境复杂度中飞行的回声定位叫声发现,主频按室外、室内0 棵树、室内1 棵树、室内5 棵树依次提高,而脉冲时程及脉冲间隔则依次缩短;室外放飞条件下的后端FM 频宽比室内飞行的短。研究结果说明,大蹄蝠在不同状态、不同生境复杂度条件下的回声定位叫声具有明显的可塑性和生境适应性。     

Testing the performances of automated identification of bat echolocation calls: A request for prudence

Echolocating bats are surveyed and studied acoustically with bat detectors routinely and worldwide, yet identification of species from calls often remains ambiguous or impossible due to intraspecific call variation and/or interspecific overlap in call design. To overcome such difficulties and to reduce workload, automated classifiers of echolocation calls have become popular, but their performance has not been tested sufficiently in the field. We examined the absolute performance of two commercially available programs (SonoChiro and Kaleidoscope) and one freeware package (BatClassify). We recorded noise from rain and calls of seven common bat species with Pettersson real-time full spectrum detectors in Sweden. The programs could always (100%) distinguish rain from bat calls, usually (68–100%) identify bats to group (Nyctalus/Vespertilio/Eptesicus, Pipistrellus, Myotis, Plecotus, Barbastella) and usually (83–99%) recognize typical calls of some species whose echolocation pulses are structurally distinct (Pipistrellus pygmaeus, Barbastella barbastellus). Species with less characteristic echolocation calls were not identified reliably, including Vespertilio murinus (16–26%), Myotis spp. (4–93%) and Plecotus auritus (0–89%). All programs showed major although different shortcomings and the often poor performance raising serious concerns about the use of automated classifiers for identification to species level in research and surveys. We highlight the importance of validating output from automated classifiers, and restricting their use to specific situations where identification can be made with high confidence. For comparison we also present the result of a manual identification test on a random subset of the files used to test the programs. It showed a higher classification success but performances were still low for more problematic taxa.
