    Bats play multifaceted roles in ecosystems, profoundly impacting both the environment and human societies through their diverse ecosystem services. This review aims to summarize the current status and future prospects of studies concerning bat ecosystem services, with particular emphasis on their roles in provisioning, regulating, cultural, and supporting services. In terms of provisioning services, bats provide valuable resources for agriculture and medicine, particularly bat guano (known as‘Ye Mingsha’), which is an important component in traditional Chinese medicine and can also serve as an efficient organic fertilizer that significantly improves soil quality and crop yields. Additionally, some biological characteristics of bats, such as anticoagulant proteins and antiviral compounds in their saliva, provide an essential basis for new drug development, driving innovation in biotechnology and medicine. In regulating services, insectivorous bats not only reduce agricultural pest populations and pesticide use but also create a‘landscape of fear’through predation risks, altering prey behavior and physiology, thereby further reducing their fitness. Frugivorous bats contribute to plant pollination and seed dispersal, improving crop production sustainability and enhancing ecosystem health. In cultural services, the image of bats holds significant symbolic meaning in both Eastern and Western cultures and contributes to local economies through eco-tourism. In supporting services, bats maintain ecosystem health and stability through seed dispersal, plant pollination, and nutrient cycling. The review also anticipates future research directions, underscoring the importance of protecting bats and their ecosystem services to address challenges posed by global environmental changes and to promote sustainable development in human societies.

    Bats, as proficient night-flying mammals, are effective pollinators for flowering plants in diverse lineages in tropical regions. The interactions between frugivorous/nectarivorous bats and their foraging flowers provide a valuable system for studying interspecific interactions, adaptation, and diversification. In this review, we firstly summarize the diversity of bat pollination systems, and then construct the evolutionary relationship between bats and bat-pollinated plants. To outline the adaptive characteristics of the chiropterophilous pollination system, five aspects are discussed: bat vision and flower color, olfactory and flower fragrance, echolocation and flower shape, body and flower mechanical fit (morphological match), nutritional requirements and floral rewards. Perspectives of ecology and evolution in bats and some issues worthy of further exploration are proposed.

    Acoustic communication is a crucial phenotype for animals to maintain social stability, and it has always been a hotspot in the field of animal behavior research. Bats, as key group in ecosystems, primarily rely on acoustic signals to move around in environments and have long been model organisms for acoustic research. Here, we provide a comprehensive overview of communication calls in bats and propose future development directions. In general, bat communication calls exhibit diverse spectral structures, encode various information about individual identity, body size, or social status, and serve functions including defense and alarm, courtship and mating, and social bonding. Bats can adjust the structure, intensity, and complexity of their calls in response to noise interference. Bat communication calls exist geographic variation and possess syntactic structure, vocal rhythm, and complexity. Additionally, bats exhibit vocal learning and variability in sound development. Compared to echolocation calls, research on bat communication calls is relatively lacking. We recommend that future studies should focus on the multi-level evolutionary aspects of bat communication calls, innovate sound analysis methods, develop high-performance on-board sound recording devices, establish a global bat acoustic database, strengthen interdisciplinary collaborations, and conduct long-term systematic observations to advance the field of bat communication calls research.

    Hipposideros armiger (Chiroptera: Hipposideridae) is traditionally categorized into four recognized subspecies: H. a. armiger, H. a. fujianensis, H. a. terasensis, and H. a. traninhensis. In China, the first three subspecies are known to be widely distributed across 16 provinces. However, the validity of this subspecies classifacation is still debated. In order to reassess and clarify the subspecies classification status of H. armiger, based on samples recently collected from Xizang, which are geographically close to the type locality in Nepal, we integrated morphological and molecular data and evidences from samples from various provinces. Our findings indicate a lack of significant morphological and cranial metric differences among H. a. armiger, H. a. fujianensis, and H. a. terasensis. The phylogenetic analysis revealed that sequences from China forming a well-supported distinct lineage, with sequences from Fujian and Taiwan nested within this lineage. The genetic distances among the three subspecies are minimal, ranging from 0. 002 to 0. 013.The haplotype network analysis also reveals no significant population genetic structure or geographic differences among three subspecies. The morphological and molecular evidence presented herein supports the reclassification of H. armiger in China as a single subspecies, H. a. armiger. This results not only clarifies the subspecies classification of H. armiger in China, but also provides foundational data for future research on phylogeography and conservation status.

    Artificial light has altered the nocturnal environments of most ecosystems, posing a threat to biodiversity and associated ecosystem services. Foraging behavior is essential for animals to obtain the nutrition and energy from the external environment. To date, it remains uncertain whether the intensity of artificial light affects the foraging behavior in nocturnal animals. Here, we used Japanese pipistrelle bats (Pipistrellus abramus) as a model for insectivorous bats to investigate the effects of artificial light intensity on their foraging behavior. We established three study sites situated 5 m below three different bridges. At each site, we monitored the intensity of artificial light and recorded the number of passes and feeding buzzes in P. abramus. The Kruskal-Wallis test showed no significant difference in the number of P. abramus passes between the relatively dark site and the site with low light intensity. However, a remarkable reduction in the number of P. abramus passes was observed at the site with high light intensity when compared to the relatively dark site. There was an increasing tendency in the number of feeding buzzes emitted by P. abramus at the site with low light intensity relative to the relatively dark site. The number of feeding buzzes in P. abramus was significantly diminished at the site with high light intensity relative to the site with low light intensity. Generalized linear mixed models indicated that the intensity of artificial light negatively influenced the number of passes and feeding buzzes in P. abramus. These results demonstrate that high levels of artificial illumination can disturb the foraging behavior of P. abramus. Our findings provide a scientific basis for the regulation of light pollution in habitats utilized by synanthropic bats.

    Caves are important habitats for bats, often serving as breeding sites, hibernacula, and temporary nocturnal roosts for a wide range of species. Cave utilization studies are thus key to bat conservation. From June to August 2023 and from December 2023 to February of the following year, we conducted bat species and population surveys in Gu cave in Shanmen Town, Siping City, Jilin Province, to explore the cave utilization strategies of five sympatric bat species. Daytime observations revealed that Rhinolophus nippon roosted in Gu cave during summer, and one Myotis ikonnikovi roosted in the cave on July 15th only. Cluster size of R. nippon decreased and then increased overall from June to August. We recorded two instances of R. nippon mothers holding their young in July. Echolocation of four species of FM bats (Hypsugo alaschanicus, Pipistrellus abramus, Vespertilio sinensis, and Myotis ikonnikovi) was recorded during the summer by night time acoustic sampling. Kruskal-Wallis test and Bonferroni multiple comparisons analysis showed that the number of echolocation pulses of P. abramus, V. sinensis, and M. ikonnikovi did not differ significantly between summer months, and that of H. alaschanicus differed significantly between July and August. During the nine sampling occasions in summer, the average peak emergence period of R. nippon ranged from 15 min to 60. 56 min after sunset, and the average end time of emergence was (60. 56 ±5. 27) min after sunset. Pipistrellus abramus and M. ikonnikovi ap‐peared at the peak of the activity of R. nippon on one occasion and five occasions, respectively, and H. alaschanicus and V. sinensis appeared after the peak of the activity of R. nippon, which suggests that the four species only temporarily roosted at night in the cave. No echolocation pulses from the five bat species were recorded during the winter. The results suggest that the Gu cave is used as a summer breeding site by R. nippon and as a temporary roosting site at night for the other four species of bats, and is not utilized in winter. The results of this study reveal the cave utilization strategies of the five sympatric bat species and provide a reference for subsequent bat habitat conservation and management.

    Hibernation plays a vital role in the reproductive success and sustainability of bat populations. Prior studies have recognized the artificial channel tunnels in Jiyuan, Henan, as important hibernation habitats for bats, with annual increases in hibernating populations and variations in hibernation patterns. Nonetheless, the extent of dynamic fluctuations in species composition and individual numbers of hibernating bats during hibernation remains uncertain. To address this, we conducted four surveys assessing the population dynamics of hibernating bats in this region from November 2023 to February 2024. Although historical data indicated a consistent upward trend in hibernating populations, our monitoring from 2023 to 2024 revealed no significant increase in the overall population. Notably, there was a shift in species composition: Murina aurata was absent, while Rhinolophus episcopus was newly recorded. The proportion of bat numbers among different bat species showed minimal fluctuation, with R. nippon remaining the predominant species, followed by R. pusillus. The population demonstrated consistent fluctuations during the hibernation period, with overall numbers remaining stable in November and December, peaking in January, and reaching their lowest point in February. Spatially, the proportion of hibernating individuals in areas with low-temperature fluctuations, located less than 30 meters from the cave entrance, decreased from a historical 20. 0% to 7. 8%. The hibernating population of R. pusillus demonstrated considerable variability, indicating a preference for warmer areas. Notably, the extreme cold wave events from December 2023 to February 2024 exacerbated microclimate fluctuations at the cave entrance, prompting spatial redistribution and adjustments in the population dynamics of hibernating bats. Our subsequent investigations revealed that numbers of hibernating bats undergo dynamic changes, with both population size and habitat selection during hibernation may be influenced by changes in external environmental conditions. These findings enhance the ecological understanding of bat hibernation in China and provide scientific evidence on the impact of extreme environmental conditions on hibernating bat populations.

    To explore and clarify the bat species diversity in China, a series of bat surveys were carried out in Hunan Province and Fujian Province. From September 2022 to July 2023, 9 bats (5♂, 4♀) were collected using harp traps in Huaihua and Shaoyang cities in Hunan Province, and in Wuyishan City, Fujian Province. These bats are relatively small, with forearm length ranging from 28. 70 mm to 32. 80 mm, and with black noses and short tube-like nostrils. Dorsal fur has a banded appearance, with a dark gray base, light yellow middle band, and blackish tip. Ventral fur is orange-yellow. Throat fur is banded with a gray-white base and light yellow/orange tip. Their skulls are relatively small, ranging from 15. 15 mm to 16. 39 mm, and exhibit a prominent rostrum, indistinct lambdoid sutures, and lack a sagittal crest. These characteristics are consistent with those of Murina shuipuensis. Phylogenetic analysis based on the Cyt b sequence segment confirmed this identification. The specimens are deposited at the Key Laboratory of Biodiversity Dynamics and Conservation of South China, Guangzhou University, and represent a new bat species record in Hunan and Fujian provinces. Moreover, to predict the potential suitable habitats for M. shuipuensis in China, we applied Ensemble Species Distribution Models (ESDM). We collected 30 distribution points of M. shuipuensis and selected 11 less-correlated environmental variables. The Ensemble function in the R package ‘SSDM’ was used to infer the ensemble model and predict the potential suitable habitats. The performance of the model was evaluated based on AUC and Kappa values. The prediction result was superimposed with distribution points and geographical base map using QGIS to obtain a prediction map of potential suitable areas. We found that the distribution of this species is mainly related to precipitation factors, and tends to be far from human disturbance areas. Regions with high habitat suitability are predominantly located in the mountainous areas of South, East, and Central China, concentrated in northwestern Hunan, northern Guangdong and Guangxi, central to northern Fujian, and central to southwestern Zhejiang. Moderate suitable areas surround the highly suitable area. Overall, suitable areas are closely related to mountains, mainly around Nan Ling, Wuyi Mountains, and Luoxiao Mountains. These predictions could benefit future bat field surveys. The specimens are deposited at the Key Laboratory of Biodiversity Dynamics and Conservation of South China, Guangzhou University presently.

    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, Houjiazhuang 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 external morphology, cranial parameters, and molecular phylogenetic analysis (Cyt b and ND1 genes), the captured individuals 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 frequency modulation, short downward frequency modulation, and wrinkled frequency modulation) and one compound syllable (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.

    In July 2022, eight long-eared bats (consisting of 2 females and 6 males) were captured in a mine in Inner Mongolia, China using mist nets. These bats had a medium body size, in the range of one of the largest species of Plecotus, with mostly naked faces and large ears. Their ear membranes and wings were light brown and slightly transparent. The ear tragus was lighter in color than the ear membrane. The back fur was brownish yellow and the belly fur was light gray to white. Their skulls had a distinct depression in the forehead area and on the top of the head, and a large auditory bullae. The dental formula was 2. 1. 2. 3/3. 1. 3. 3 = 36, featuring slender canine teeth and tiny upper outer incisors and first premolars, and their lower second premolars were slightly smaller than first premolars. These characteristics are in line with those of Plecotus kozlovi. Genetic differences and phylogenetic analysis based on mitochondrial cytochrome b (Cyt b) gene sequences support the morphological identification. This study constitutes the first field record and rediscovery of P. kozlovi in China, confirming that the species still exists in the country and adding to the country’s bat species records.

    A bat survey was conducted in Nanjing Fangshan Scenic Area and Jiangsu Yancheng Wetland and Rare Birds National Nature Reserve in Jiangsu Province in July 2023. Two male bats were captured using mist nets and hand-held nets. One specimen is small, with a forearm length of 34. 0 mm. Its ear is long and narrow and the tragus is straight and slender, reaching half the length of the ear. The skull is long and narrow, with a total cranial length of 12. 8 mm. The cranium is full and prominent. The sagittal ridge is thin, and the herringbone ridge is not obvious. The dental formula is 2. 1. 3. 3/3. 1. 3. 3 = 38. These characteristics are consistent with Myotis siligorensis. The other specimen is mediumsized, with a forearm length of 48. 4 mm. The wings are long and narrow, and are inverted when resting. The ears are short and round with a small tragus. The snout is low and slightly wide, with the tip slightly upturned and the middle slightly concave. The cranium is high, large and round, with a total cranial length of 16. 0 mm. The sagittal ridge is low and slender and the herringbone ridge is not obvious. Dental formula is 2. 1. 2. 3/3. 1. 3. 3 = 36. These characteristics accord with those of Miniopterus fuliginosus. The identification was further validated by phylogenetic inference using Cyt b gene. Therefore, the bats collected in this study are identified as Myotis siligorensis and Miniopterus fuliginosus respectively, which are new bat records in Jiangsu Province. Our finding enriches the knowledge of bat diversity and distribution in Jiangsu Province.

    During a investigation of Chiroptera diversity in Guangxi Zhuang Autonomous Region, seven Myotis bats (3 males and 4 females) were captured from May to June, 2023 in Tuoqi water conservancy tunnel, Youliaogu water conservancy tunnel, and G80 culvert in Tianyang District, and in Lilangtun tunnel in Leye County, all in Baise City, Guangxi Zhuang Autonomous Region. The species of the aforementioned specimens were identified using a combination of traditional morphological methods and molecular phylogenetic analysis. Among the captured specimens, four bats were small to medium size, with forearm lengths of 33. 7 - 37. 4 mm. The dorsal hairs are dark brown to black, with light gray on the abdominal hair tips near the tail, and the wings are a uniform dark brown. The skull is long and narrow, with a robust snout, relatively flat skull roof, and delicate cranial bones, with a noticeable slope at the frontal bone. These morphological characteristics and measurements are consistent with Myotis horsfieldii. The other three bats were medium-sized, with forearm length of 45. 2 - 45. 5 mm. The dorsal hairs are long and dark brown, with light yellow-brown tips on the abdominal hairs, and the wings are of a single color and attach at the base of the first toe. The skull is massive with a broad and short rostrum; the cranial profile is flattened. Zygomata are strong, and the sagittal and lambdoid crests are well pronounced. The morphological characteristics and measurements are consistent with those of Myotis indochinensis. Phylogenetic analysis based on the Cyt b gene also supported the above morphological identification results. This report represents a new distribution record of M. horsfieldii and M. indochinensis in Guangxi Zhuang Autonomous Region. The specimens are kept in the Institute of Zoology, Guangdong Academy of Sciences.

    In July 2022 and July 2023, two bats were captured using mist nets in Jian Village, Dongguan Town, Qixian County, Jinzhong City, Shanxi Province, and Qianlijia Village, Huoshui Town, Wuan City, Hebei Province, respectively. The external morphology of the samples from Shanxi and Hebei were assessed, echolocation sound waves were recorded, and Cyt b sequences were amplified from the wing membrane. Additionally, the skulls of the Shanxi and Hebei specimens were dissected and measured. The fur color of the two specimens exhibited a light hue with a dark brown root. They exhibited darker ears and faces, with the wing membrane originating at the base of the toe, the tail membrane at the ankle joint, and the tail extending beyond the tail membrane by approximately 3 mm. Their forearm lengths are 34. 3 mm and 35. 6 mm, tail lengths are 38. 5 mm and 40. 2 mm, ear lengths are 10. 9 mm and 10. 5 mm, and the greatest length of the skull are 13. 0 mm and 14. 0 mm. External and cranial measurements were consistent with those of Hypsugo alaschanicus. Their echolocation calls exhibited frequency modulation (FM) and peak frequencies of 60. 0 kHz and 64. 2 kHz. Analysis of the phylogenetic tree constructed using Cyt b gene sequences indicated that the samples from Shanxi and Hebei formed a cluster with H. alaschanicus, consistent with the results of morphological characterization. The H. alaschanicus specimen from Shanxi represents a new Chiroptera record in the province.
