贵州洋溪省级自然保护区翼手类 物种多样性调查

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。     

太行山南段洞栖蝙蝠的分布及栖息地重要性分析

2009年8月至2010年9月,对太行山南段的洞栖蝙蝠及栖息地进行了调查,共调查洞穴38个,其中28个洞穴为首次调查,共观察到蝙蝠约17000只,隶属2科4属9种,其中分布最广、数量最多的是马铁菊头蝠。测量洞穴的总水平长度、最大宽度和最大高度,并以洞穴内蝙蝠的种群数量(Ai)与根据物种生存状态赋值的权重(Mi)乘积之和评估洞穴重要性。在调查的洞穴中,最重要的洞穴是黄楝树水渠,有8种约2500只蝙蝠在此繁殖和冬眠;其次是涧河洞,有5种约2100只蝙蝠在此繁殖和冬眠。基于洞栖蝙蝠种类和洞穴测量数据的聚类及主成分分析,探讨了太行山南段东西两侧洞栖蝙蝠的分布状况、不同类型栖息地之间的差异以及洞栖蝙蝠对栖息地的选择。太行山南段东西两侧洞栖蝙蝠的种类和种群数量差异不显著。冬眠洞穴的总水平长度、最大宽度、最大高度、郁闭度均显著大于非冬眠洞穴。影响蝙蝠栖息地选择的主要因子有地形因子、隐蔽因子和干扰因子,这3个主成分的累计贡献率达到85.96%。目前,这些洞穴的保护现状均不理想,一些洞穴已经或正在被开发成旅游景点,这使该地区洞栖蝙蝠面临严重的生存危机。本研究结果以期能为决策者在制定开发旅游策略时提供参考和依据。     

澳门翼手类物种多样性调查

2009～2012年,对澳门翼手目(蝙蝠)物种多样性进行了调查.结果共捕捉到10个物种,属5科8属,其中包括澳门原来记载的2个物种,即蹄蝠科的大蹄蝠(Hipposideros armiger)和蝙蝠科的东亚伏翼(Pipistrellus abramus);本研究新增加8个物种,即狐蝠科的犬蝠(Cynopterus sphinx)和棕果蝠(Rousettus leschenaulti),鞘尾蝠科的黑髯墓蝠(Taphozous melanopogon),菊头蝠科的菲菊头蝠(Rhinolophus pusillus),以及蝙蝠科的大足鼠耳蝠(Myotis ricketti、普通伏翼(P.pipistrellus)、普通长翼蝠(Miniopterus schreibersi)和南长翼蝠(M.pusillus).另外,通过野外录音和分析,并与已发表物种声音特征比较核对,发现菊头蝠科和蹄蝠科各一种,前者可能是泰国菊头蝠(R.siamensis)或者中菊头蝠(R.affinis),后者可能是果树蹄蝠(H pomona)或者三叶蹄蝠(Aselliscus stoliczkanus).本文对已捕捉10种蝙蝠的分布、形态特征和回声定位叫声特征进行报道,同时对其种群数量和保护现状进行了讨论.保护蝙蝠栖息生境(洞穴、古老建筑和蒲葵树等)对保护澳门蝙蝠物种多样性至关重要.     

贵州省松桃县东部地区翼手目物种多样性

2008年7月至2009年2月,对贵州省松桃县东部地区的14个镇(乡)47洞穴翼手目的种类、数量、分布及生境进行调查研究。通过标本的采集、鉴定,确定该地区共有翼手目动物3科14种,其中2种为待定种;爪哇伏翼(Pipistrellus javanicus)、棒茎伏翼(P.paterculus)、单角菊头蝠(Rhinolophusmonoceros)3种在贵州省首次发现,其中单角菊头蝠是在中国大陆首次发现。另外,还对该地区蝙蝠的冬眠行为、对冬眠地的选择以及栖息环境的受胁现状进行了初步调查,发现不同种类蝙蝠的冬眠行为是不一样的;同时发现,洞外捕食生境的不同会造成洞穴内分布翼手目种类的不同。

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。     

A faunal survey of streblid flies (Diptera: Streblidae) associated with bats in Paraguay

An extensive survey of the ectoparasites infesting bats in Paraguay provides information regarding the taxonomy and host distribution of streblid bat flies at a geographic interface between subtropical and temperate habitats. Five families of bats representing 45 species, including Molossidae (5 genera and 15 species), Natalidae (1 genus and 1 species), Phyllostomidae (11 genera and 15 species), Noctilionidae (1 genus and 2 species), and Vespertilionidae (4 genera and 12 species) were collected from 24 localities across Paraguay and sampled for ectoparasites. In total, 2,467 bat flies were collected, representing 11 genera and 31 nominal species of Streblidae, of which 6 genera and 24 species are new records for Paraguay. No streblids were collected from vespertilionid bats; 23 species infested phyllostomids, 6 species noctilionids, 1 species a natalid, and 1 species molossids. Streblid bat flies were highly specific to certain host groups and individual host species, and their geographic distributions closely followed those of their host bats. Of 31 streblid species surveyed, 27 were monoxenous (i.e., associated with a single host species), and 4 were stenoxenous (i.e., associated with a group of phylogenetically related hosts). The number of streblid species is greatly reduced in the Chaco region west of the Paraguay River, largely because of the lack of phyllostomid host bats.

<正>翼手目为哺乳动物中的第二大目,中国的翼手目多样性也在不断更新,Smith和解焱(2009)统计中国翼手目118种,蒋志刚等(2015)则认为中国翼手目有7科34属134种。广东省翼手目有6科24属55种(邹发生和叶冠锋,2016),此后也仍陆续有新纪录,如长指鼠耳蝠(Myotis longipes)(张琴等,2017)、卡氏伏翼(Hypsugo cadornae)(Xie et al., 2021);我们前期对澳门翼手目的调查,发现5科8属10种(黄继展等,2013)。     

海口地区犬蝠冬季食性及栖宿地类型

犬蝠(Cynopterus sphinx)是海口地区较为常见的一种果蝠,属于近危兽类。对其生态学研究有助于了解犬蝠在生态系统中的作用,并为野生动物管理提供基础资料。从2005年10月至2006年1月,采用直接观察法、拾遗法、粪便分析法并结合雾网采样法对本地区犬蝠冬季的栖宿地类型及食性进行了研究。结果发现,犬蝠主要栖宿在椰子等棕榈科植物的大型叶片下以及废弃的房屋中;其食物包括9科11种植物的果实、2科2种植物的叶片和1种植物的茎。     

扁颅蝠与褐扁颅蝠的集群结构

2001—2002年在广西宁明县和龙州县利用直接观察、捕捉测量(共捕到197群蝙蝠,全捕180群)和标记重捕法(标记了31群的101只扁颅蝠,重捕到36只)比较研究了扁颅蝠(tylonycteris pachypusa)与褐扁颅蝠(T．robustula)的集群结构。结果发现：扁颅蝠与褐扁颅蝠主要栖宿在刺竹(Bambusa stenostachya)的竹筒内,通过竹筒上的裂缝进出。扁颅蝠栖宿的竹筒长平均为27．7cm,外围直径平均为23．6cm;褐扁颅蝠的分别为28．3cm和23．8cm。扁颅蝠栖宿群大小为1—24只,褐扁颅蝠栖宿群大小为1—13只;2种蝙蝠的栖宿群中皆为独居所占比例最大(扁颅蝠为22．30％,褐扁颅蝠为40．63％),2只所占比例次之(分别为14．87％和18．75％),其它大小类型呈不规则变化。扁颅蝠栖宿群的性别组成,以雌雄混居最常见(占54．72％),其次为独居雄性(占20．95％),而褐扁颅蝠栖宿群雌雄混居群与独居雄性所占比例相当(均为40．63％)。2种蝙蝠的雄性趋向于独居,而雌性趋向于群居。扁颅蝠与褐扁颅蝠可以栖宿在同一片竹林内,并且可以在不同时间轮流使用同一个栖宿竹筒,但2种蝙蝠从未共栖于同一个竹筒内。另外,标记重捕扁颅蝠发现：扁颅蝠经常变换栖宿竹筒(栖宿竹筒不固定);同时栖宿群之间经常发生个体交换[动物学报50(3)：326—333．2004]。     

Seed Dispersal of Morus macroura (Moraceae) by Two Frugivorous Bats in Xishuangbanna, SW China

The dispersal of Morus macroura seeds by two species of frugivorous bats ( Rousettus leschenaulti and Cynopterus sphinx ) was studied in a forest at Xishuangbanna Tropical Botanical Garden in Southwest China from March to May 2005. Feeding roosts were identified within 500 m around parent trees and the types and number of seed loads under each roost were recorded. We found feeding roost density decreased with increasing distance from the parent, but found no correlation between distance and seed deposition. The effect of bat digestion on seed germination was investigated, and we found that germination percentage of all treatments involving ingestion by bats was significantly lower than control seeds and some germination parameters of seeds from different treatments changed.     

四川绵阳洞栖蝙蝠多样性及受胁现状

Isolation of fungi from bats of the Amazon basin.

A total of 2,886 bats captured in the Amazon Basin of Brazil were processed for the isolation of fungi. From the livers, spleens, and lungs of 155 bats (5.4%), 186 fungal isolates of the genera Candida (123 isolates), Trichosporon (26 isolates), Torulopsis (25 isolates), Kluyveromyces (11 isolates), and Geotrichum (1 isolate) were recovered. Seven known pathogenic species were present: Candida parapsilosis, C. guilliermondii, C. albicans, C. stellatoidea, C. pseudotropicalis, Trichosporon beigelii, and Torulopsis glabrata. Twenty-three culture-positive bats showed identical fungal colonization in multiple organs or mixed colonization in a single organ. The fungal isolation rates for individual bat species varied from 1 fungus per 87 bats to 3 fungi per 13 bats, and the mycoflora diversity for members of an individual fungus-bearing bat species varied from 16 fungi per 40 bats to 7 fungi per 6 bats. Of the 38 fungal species isolated, 36 had not been previously described as in vivo bat isolates. Of the 27 culture-positive bat species, 21 had not been previously described as mammalian hosts for medically or nonmedically important fungi.

Seasonal variation in age,sex, and reproductive status of Mexican free-tailed bats

In North America, Mexican free-tailed bats (Tadarida brasiliensis mexicana) consume vast numbers of insects contributing to the economic well-being of society. Mexican free-tailed bats have declined due to historic guano mining, roost destruction, and bioaccumulation of organochlorine pesticides. Long-distance migrations and dense congregations at roosts exacerbate these declines. Wind energy development further threatens bat communities worldwide and presents emerging challenges to bat conservation. Effective mitigation of bat mortality at wind energy facilities requires baseline data on the biology of affected populations. We collected data on age, sex, and reproductive condition of Mexican free-tailed bats at a cave roost in eastern Nevada located 6 km from a 152-MW industrial wind energy facility. Over 5 years, we captured 46,353 Mexican free-tailed bats. Although just over half of the caught individuals were nonreproductive adult males (53.6%), 826 pregnant, 892 lactating, 10,101 post-lactating, and 4327 nonreproductive adult females were captured. Juveniles comprised 11.5% of captures. Female reproductive phenology was delayed relative to conspecific roosts at lower latitudes, likely due to cooler temperatures. Roost use by reproductive females and juvenile bats demonstrates this site is a maternity roost, with significant ecological and conservation value. To our knowledge, no other industrial scale wind energy facilities exist in such proximity to a heavily used bat roost in North America. Given the susceptibility of Mexican free-tailed bats to wind turbine mortality and the proximity of this roost to a wind energy facility, these data provide a foundation from which differential impacts on demographic groups can be assessed.
