An astonishing number of bat fatalities (2,371 belonging to 15 species) were recovered in a provincial surveillance program at wind farms in Cádiz, at the southern tip of Spain, in 2005–2016. We carefully analysed a subset of this sample intending to estimate the true fatality rate in the year 2011, the year for which we had the richest data set (582 fatalities at 38 wind farms). To estimate the true fatality rate, we conducted search-efficiency and scavenger-removal trials in nine wind farms involving 122 turbines and 289 observed fatalities and calculated the searchable surface. An annual fatality rate of 41.1 dead bats per turbine (26.4 per MW) was estimated in the study area using a self-developed estimator due to the singularities of the surveillance program. Our estimator results are lower than those obtained using the Generalized Mortality Estimator (GenEst) developed by U.S. Geological Survey. Estimates of 37,689 or 33,370 fatalities were made according to the province's number of turbines or MW in 2011. Some areas have registered the highest fatality rates ever recorded for bats in wind turbines anywhere globally, even more so because we have been conservative. There is an urgent need for efficient preventive and mitigation measures at wind farms in risky landscapes and with a high rate of bat fatalities, but trials are also needed to know how well the post-operational monitoring is done and how far it is from reality. Clearly, current official post-construction surveillance programs are inefficient for searching bats and therefore mask a high fatality rate, mainly of sedentary bats.

Human alterations of landscapes, such as habitat conversion and infrastructure buildouts have caused population declines and extinctions of numerous species. Anthropogenic change negatively impacts surrounding landscapes, but in some cases, lead to an increase in synathropy. Bats are one such group that often take advantage of human altered landscapes, roosting in anthropogenic structures such as buildings and transportation infrastructure. However, less is known about how non-traditional or artificial roost sites may affect persistence of synathropic bat species. We conducted a literature review to evaluate the ecological relationship between bats and artificial roosts, specifically transportation structures, as they are often the only roost structures available in some landscapes. Our evaluation revealed that numerous studies on artificial roost selection have been conducted in the eastern region of North America, as well as abroad. Use of transportation structures by bats varies across landscapes, specifically due to variation in annual climate, availability of natural roosts, and bridge structure design. This review enhances our understanding of bat roost ecology, possible pitfalls of synanthropic behaviour, and identify trends related to bat-bridge associations that may improve conservation outcomes for synanthropic species.

The chiropteran collection that has been recovered from the two chronologically different fossiliferous assemblages of the Loutra Almopias Cave A (Pella, Macedonia, Greece) is studied. The specimens retrieved from the cave's floor sediments (LAC) are of the Late Pleistocene, whereas the specimens retrieved from the elevated chamber LAC Ia are of latest Pleistocene age. The first comprehensive systematic taxonomy and biogeographic analysis of a fossil chiropteran fauna from the Greek region was accomplished, based on the determination of the 9,004 chiropteran specimens. This resulted in the identification of 17 species from LAC and 20 from LAC Ia from three families (Rhinolophidae, Vespertilionidae, Miniopteridae) and nine genera (Rhinolophus, Myotis, Nyctalus, Pipistrellus, Vespertilio, Eptesicus, Plecotus, Barbastella, Miniopterus). Seven bat species described from the Loutra Almopias Cave A are the first known records in Greece and one species is the first Late Pleistocene record from the Balkan Peninsula. Eighteen species refer to the southernmost appearance of the Late Pleistocene of the Balkan Peninsula. Loutra Almopias Cave A served primarily as a nursery roost for many bats, and secondarily as a warm refuge during colder periods. Almost all of the chiropteran species described in this paper are now permanently resident in the region adjacent to the cave. Almost all bat species found in the Loutra Almopias Cave A are also present in the records of several localities from the Balkan Peninsula as Similarity analysis between the chiropteran faunas is indicative of an equivalent distribution in the region during the Late Pleistocene. In conclusion, the Late Pleistocene bat fauna from the Loutra Almopias Cave A is, up to date, the richest and most diverse not only from the Greek region, but also from the Balkan Peninsula.

Alopecia, or alopecia syndrome is the partial or complete loss of hair from an animal's body. Following a previous report on bats with alopecia, in this work we complemented the list of bat species with alopecia available in the literature through 2023, adding phyllostomids (Artibeus planirostris, Carollia perspicillata), an emballonurid (Peropteryx pallidoptera), molossids (Molossus rufus, Nyctinomops macrotis), and vespertilionids (Corynorhinus rafinesquii, Eptesicus fuscus, Nycticeius humeralis, Myotis austroriparius, M. grisescens, M. velifer). We also explored factors that may explain alopecia in the first records of this condition in ten Pteronotus mesoamericanus females from Oaxaca, southeastern Mexico, recorded from November 2020 to January 2022. In those individuals, hair loss was observed on the back and head; six of them were lactating and four showed no evidence of reproductive activity. In addition, we documented alopecia on the thorax in four individuals of three species: Artibeus lituratus (one pregnant female and one male with scrotal testes), Pteronotus fulvus (one pregnant female), and Artibeus toltecus (one pregnant female). The alopecic bats presented mild alopecia (the affected area ranged from 1–5 cm2), and only one female showed moderate alopecia (8.1 cm2). Alopecia in P. mesoamericanus, P. fulvus, A. toltecus, and A. lituratus may be due to hormonal or nutritional imbalances associated with reproduction. In addition, in A. lituratus it may also be the result of environmental stress when foraging in an urban area. The causal agents of alopecia in bats are still not fully known, and it is probably a multifactorial phenomenon. La alopecia, o síndrome de alopecia es la pérdida parcial o total del pelo del cuerpo de un animal. Siguiendo un informe previo sobre murciélagos con alopecia, en este trabajo complementamos la lista de especies de murciélagos con alopecia disponibles en la literatura hasta 2023, agregando filostómidos (Artibeus planirostris, Carollia perspicillata), un embalonúrido (Peropteryx pallidoptera), molósidos (Molossus rufus, Nyctinomops macrotis) y vespertiliónidos (Corynorhinus rafinesquii, Eptesicus fuscus, Nycticeius humeralis, Myotis austroriparius, M. grisescens, M. velifer). También exploramos los factores que pueden explicar la alopecia en los primeros registros de esta condición en diez hembras de Pteronotus mesoamericanus de Oaxaca, sureste de México, registradas desde noviembre de 2020 hasta enero de 2022. En esos individuos se observó pérdida de pelo en el dorso y la cabeza; seis de ellos estaban lactando y cuatro no mostraron evidencia de actividad reproductiva. Además, documentamos alopecia en el tórax en cuatro individuos de tres especies: Artibeus lituratus (una hembra gestante y un macho con testículos escrotados), Pteronotus fulvus (una hembra gestante) y Artibeus toltecus (una hembra gestante).

秃发或秃发综合症是指动物身体部分或全部失去毛发。继之前关于秃顶蝙蝠的报道之后，本研究补充了截至2023年文献中已有的秃顶蝙蝠物种列表，增加了phyllostomids (Artibeus planirostris, Carollia perspicillata)、ballonurids (Peropteryx pallidoptera)、Molossus rufus、Nyctinomops macrotis)和vespertilionids (Corynorhinus rafinesquii、Eptesicus fuscus、Nycticeius humeralis、Myotis austroriparius、M. grisescens、M. velifer)。我们还在2020年11月至2022年1月记录的墨西哥东南部瓦哈卡州10只雌性中美洲翼龙的首次记录中探索了可能解释脱发的因素。在这些人中，背部和头部出现脱发;其中6只正在哺乳，4只没有显示出生殖活动的迹象。此外，我们还记录了3个物种的4个个体的胸部脱发:Artibeus lituratus(1名怀孕的雌性和1名有阴囊睾丸的雄性)，Pteronotus fulvus(1名怀孕的雌性)和Artibeus toltecus(1名怀孕的雌性)。秃蝠表现为轻度脱发(发病面积为1 ~ 5 cm2)，雌蝠仅有1只表现为中度脱发(8.1 cm2)。中美洲猿人、黄斑猿人、toltecus猿人和lituratus猿人的脱发可能是由于与生殖有关的激素或营养失衡。此外，在城市地区觅食时，也可能是环境压力的结果。蝙蝠脱发的致病因子尚不完全清楚，它可能是一个多因素现象。秃发症，也就是síndrome秃发症是一种特殊的疾病，特别是在动物身上。2009年1月1日，在文献资料中，我们发现了斑秃的murciciosis，并发现了斑秃的murciciosis，并发现了斑秃的murciciosis。我们发现了filostómidos (planirostris, carcarlia perspicillata)， embalonúrido (peroptertera)， molósidos (Molossus rufus, Nyctinomops macrotis)和vespertiliónidos (Corynorhinus rafinesquii, Eptesicus fuscus, Nycticeius humeralis, Myotis austroriparius, M. grisescens, M. velifer)。加入exploramos危险因素是乙醇explicar拉脱发在洛杉矶首先registros esta身体en diez de hembras de Pteronotus mesoamericanus德瓦哈卡州,墨西哥sureste registradas desde noviembre 2020直到enero区2022。所有个人都看到observó passrdida de pelo En el dorso y la cabeza;这两种动物都有繁殖能力，但没有证据表明它们有繁殖能力。Además, documentamos alopecia en el tórax en cuatro individuos de res species: Artibeus lituratus (una hembra gestante) y un macho con testículos escrotados)， fulonotus (una hembra gestante) y Artibeus toltecus (una hembra gestante)。murciciacos和alopacacos表现为脱发级别(el área afectada osciló中心1-5 cm2)，而solo una hembra presentó中度脱发(8.1 cm2)。黄斑病、黄斑病、黄斑病、黄斑病、黄斑病、黄斑病、黄斑病、黄斑病、黄斑病、黄斑病、黄斑病、黄斑病、黄斑病等。Además, za . lituratus tamamicans和tamamicans的环境关系与tamamicans的环境关系与tamamicans的环境关系与tamamicans的环境关系área urbana。造成斑秃的主要原因aún与完全性差无关，但可能是多因素的fenómeno。

Monitoring of animals over extended periods provides valuable information about their ecology and behaviour. Marking methods have been proposed and successfully used for numerous species, and yet a reliable, inexpensive method has not been found for bats. Available methods, including wing bands and collars, have also caused injury, and, in some cases, lead to death. We propose wing tattoos as an alternative method, as this has been extensively used to mark small mammals in both laboratory and field conditions. Initially we used tattoo equipment from the Animal Identification and Marking System (AIMS™, Canada), but adapted this and bought commercially available tattoo equipment, for human use, to set up our own tattoo system. We captured and tattooed 7,711 bats from 12 species across four years at three locations in South Africa between January 2013 and December 2019. Of these animals a total of 439 were recaptured with one individual captured 2,465 days after the initial tattoo, indicating the longevity of this method. In a captive population of Rousettus aegyptiacus, wing tattoos had no measurable negative effect on the animals, with no deaths and no infections, and remained legible over 927 days. Wing tattoos offer a non-lethal, cost-effective and long-lasting method to mark bats and monitor populations over long distances.

Of these animals a total of 439 were recaptured with one individual captured 2,465 days after the initial tattoo, indicating the longevity of this method. In a captive population of Rousettus aegyptiacus, wing tattoos had no measurable negative effect on the animals, with no deaths and no infections, and remained legible over 927 days. Wing tattoos offer a non-lethal, cost-effective and long-lasting method to mark bats and monitor populations over long distances.","PeriodicalId":50904,"journal":{"name":"Acta Chiropterologica","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2023-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49325810","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lonchophylla is a genus of currently 13 nectar-feeding bat species found throughout Central and South America, including Lonchophylla mordax Thomas, 1903, a species endemic to Brazil. Currently nationally categorized as ‘Data Deficient’, L. mordax has several knowledge gaps, including basic ones on its natural history. Here, we provide information on L. mordax’s pattern of nocturnal activity, reproductive peak, sex and age ratios, its relationship with ectoparasites, as well as its distribution and taxonomy. Fieldwork was conducted in the Caatinga (seasonally dry tropical forest) in north-eastern Brazil between 2012 and 2015, during which we captured 110 L. mordax individuals. Our results showed that there was no significant difference in body mass or forearm length between males and females, with a sex ratio of 1:1. We obtained four adult individuals for every subadult captured. Lonchophylla mordax individuals were active throughout the entire sample night period but with a significant peak in activity in the first 30 min after sunset. The number of captures was strongly negatively correlated with minutes after sunset. Pregnant females were captured between July and February, and subadults were captured mainly in July and August, suggesting that the peak of births occurred at the end of the dry period and the beginning of the rainy period in the study area. Additionally, almost 70% of L. mordax individuals were parasitized by streblid flies, with no significant difference in parasite load observed across seasons, sexes, and ages. However, the individuals’ body condition index was negatively correlated with the parasite load. Natural history research, such as that described here, helps to fill knowledge gaps on L. mordax, including providing data for the decision-making in conservation plans. Moreover, we add information for a species-rich genus with closely related, but poorly-studied, species globally listed as threatened or near-threatened.
