We addressed the question of why juvenile R. ferrumequinum that are born early (May to early June) in the nursery roost at Stackpole, West Wales, tend to have a higher forearm growth rate than individuals born later (late June to July). An appropriate nonlinear growth equation (either logistic, Gompertz, von-Bertalanffy, or asymptotic regression) was identified to fit the measurements of the forearms of juvenile R. ferrumequinum collected from marked individuals at the roost between 1994 and 2013. The logistic growth model provided the best line of fit to the changes in the forearm lengths, indicated by the lowest standard error. Over the 20-year study period, the mean values of the logistic growth parameters were asymptotic length (L∞) = 55.10 mm and growth constant (K) = 0.11 day-1. Multiple regression analysis indicated that the most significant predictors of the variance in L∞ and K (R2 = 58.7% and 54.3%, respectively) were the nursery roost temperatures at midnight, and the total foraging times of the adult bats during the night. If the juveniles were born early, when the roost temperature was colder, and the foraging times of the adults were shorter, then a lower value of K produced forearms that grew toward a longer L∞. If the juveniles were born late, when the roost temperature was warmer, and the foraging times of the adults were longer, then a higher value of K produced forearms that grew toward a shorter L∞. Reasons are proposed to explain the differences between the growth of early and late born individuals, including the effect of increased body mass associated with warmer roost temperatures and possible causes of longer foraging times.

The breeding biology of bats is in part regulated by environmental parameters, which in certain cases result in considerable intraspecific variation in reproduction periods. Few details are available on the reproductive behavior of Malagasy bats and this study focuses on parameters related to the mating and parturition periods in the endemic frugivorous and cave-roosting Rousettus madagascariensis (Pteropodidae). The birth period was estimated based on observations of mating behavior and presence of neonates in video recordings made at Ankarana (northern Madagascar) during different seasonal periods in 2017 and 2018. Based on animals captured in the same cave between 2014 and 2022, we also estimated the age of neonates in order to evaluate annual variation in parturition periodicity. Based on video recordings, mating was mainly observed (ordered based on highest frequency) in September, July, and January. This behavior, which generally took place during the dry season, was negatively correlated with temperature and rainfall, and had a low positive correlation with cave relative humidity. With most mating taking place between July and September, one parturition period occurs just before or during the wet season (between December and February), the period of highest fruit abundance in Ankarana. For cases of mating in January, excluding the possibility of sperm storage or delayed implantation, another parturition would occur in mid-April, a time of low fruit availability; however, no neonate was filmed or trapped in April and video recording data indicated that neonates were present between July and September, suggesting a parturition taking place from July to September. Parturition periods show some annual variation and appear to be mainly regulated by climatic aspects including rainfall and principally temperature; however, this variation was less pronounced as compared to other non-Malagasy pteropodid species. Further research on Malagasy fruit bats should focus on possible sperm storage or delayed embryonic development and, if found, associated correlations with environmental parameters.

Los reclamos acústicos para murciélagos son dispositivos capaces de reproducir ultrasonidos, y que se utilizan en investigación científica debido a la respuesta comportamental de los murciélagos frente a estímulos acústicos. Los reclamos se utilizan como atrayentes de murciélagos, generalmente durante los muestreos en campo mediante capturas. Este trabajo resume las directrices y protocolos utilizados hasta la fecha con reclamos acústicos, obtenidos a través de un formulario online distribuido ampliamente en sectores científicos y de conservación de quirópteros, mediante el que recopilamos información sobre las experiencias de sus usuarios. Recibimos 55 respuestas correspondientes a investigadores de 21 países, quienes utilizaron los reclamos en un total de 34 países, aunque predominantemente en el Reino Unido, la Unión Europea y los Estados Unidos de América. Investigaciones recientes indican que los reclamos pueden atraer a algunas especies a la vez que disuadir a otras, por lo que, principalmente, deberían usarse para proyectos centrados en especies concretas en lugar de proyectos más amplios centrados en la composición de los ensamblajes. Más de la mitad de los participantes expresaron preocupaciones éticas, afirmando que el uso de reclamos debería limitarse debido a la falta de comprensión de sus efectos secundarios sobre los murciélagos y la alteración de su comportamiento. Alentamos a los usuarios a usar los reclamos con precaución y comprobar su eficacia para que, con el tiempo, entendamos mejor sus ventajas y limitaciones. Con este fin, también recomendamos que, junto con los resultados de los estudios, se publiquen las pautas y protocolos utilizados para mejorar la comprensión sobre el funcionamiento de los reclamos, y su efecto en las especies de murciélagos a nivel global.

A Global Survey on Acoustic Bat Lures Highlights Ethical Concerns and the Need for Standardised Methods

全球声学蝙蝠诱捕器调查凸显伦理问题及标准化方法的必要性

Due to global agricultural expansion and intensification, many animal species must now survive within a landscape dominated by agroecosystems. For bats, agroecosystems can provide a valuable foraging-habitat, and many species of bats thrive within such habitats whilst also providing a range of ecosystem services for farmers. Despite this, bat usage of many agroecosystem types remains unstudied. Here, we investigated the diversity of insectivorous bats in the vanilla agroecosystems of northeastern Madagascar, the world's principal vanilla-growing region. To assess bat diversity, we used a passive acoustic survey technique, and we identified and classified bat species diversity using PCA and DFA analysis of echolocation call acoustic parameters. In total, we were able to detect the presence of at least 13 different bat species within Madagascar's vanilla agroecosystems, seven of which we were able to confidently identify to species level. However, due to our conservative classification approach, the true diversity of bats in vanilla agroecosystems is likely to be higher. The results of this study indicate that Madagascar's vanilla agroecosystems represent suitable foraging habitat for numerous bat species, particularly forest-specialists, which is a highly encouraging finding for the conservation of Madagascar's bats. Expansion of vanilla agroecosystems is therefore likely to provide valuable habitat extensions for Madagascar's forest bats in the future, provided this expansion does not come at the expense of existing largely-undisturbed natural habitats.

Many individuals of the nectar-feeding phyllostomid bat, Leptonycteris yerbabuenae, visit hummingbird feeders in southern Arizona for nearly three months each year prior to migrating back to Mexico. We monitored bat activity at four feeders with trail cameras or security cameras all night for 19–57 nights during the 2021 ‘nectar bat season’. As in previous years, peak visits occurred in mid-September. Detailed analysis of data from one feeder on 22 nights indicated that non-adults (juveniles and yearlings) were visiting it and that visitation patterns were highly variable from night to night. Statistical analysis of these patterns revealed that clusters of bats were visiting this feeder more often than expected by chance, suggesting that bats are foraging in groups. Surprisingly, bats did not leave feeders once they were drained but continued to visit them for up to five hours each night. Energetic calculations suggest that some bats are potentially expending half of their foraging energy visiting empty feeders. Studies of individually tagged bats are needed to begin to understand this behavior.

We investigated the effect of anthropogenically-driven habitat modifications on insectivorous bat activity and diversity along a stretch of the Eerste River, Stellenbosch, South Africa, by determining insect abundance, water quality and vegetation and river characteristics at four sites of varying anthropogenic impact. Passive acoustic monitoring was used to determine species composition and activity of bats at each of the sites. A total of 14,457 bat passes was recorded, with the same six species being found at each of the sites: four clutter edge foragers (Myotis tricolor, Eptesicus hottentotus, Miniopterus natalensis and Laephotis capensis) and a single clutter forager (Rhinolophus clivosus) and open-air forager (Tadarida aegyptiaca). Bat activity was greater at the lower two most eutrophied sites, and greatest at the residential (urban) site. Laephotis capensis, an urban-adapted species, was by far the most active, probably on account of both insensitivity to light pollution, and roost-site availability. The highest and most pristine site (Eiland) and the lowest and most polluted site (Spier) displayed the greatest diversity, despite highly elevated levels of chloride and nitrate at the latter site. So anthropogenic effects on water quality appear not to have negatively affected bat diversity along this stretch of the Eerste River. As these effects are likely to increase, this study serves as a baseline for future monitoring of bats along its course.

Integrated air temperature between January 1 and March 31 was recorded from 1983 to 2023 near a nursery roost of Pipistrellus pygmaeus in West Wales, U.K. Integrated air temperature was defined as accumulated heat above a threshold temperature above 5°C when Chironomid prey flew. Between 2003–2023 integrated air temperatures were in the same range (71–264 degree days) as those from 1983 to 2002 but the incidence of warm years increased. There were eight years from 2003–2023 when records were > 203 degree days compared with four years from 1983–2002. The effect on P. pygmaeus was investigated and weekly exit records from April 1 to September 27 during 1983–2002 showed six years when the first peak exit count in May–June (NJN) occurred earlier than anticipated (weeks 6–8, April 1 = week 1) so NJN counts were not within the U.K. national monitoring period (weeks 9–12). Subsequently, the probability of early NJN counts in weeks 6–8, based on the changes in the integrated air temperature January to March, was calculated. A binary logistic model predicted that for 95% of the time, the likelihood of an earlier peak exit count in six to eight weeks exceeded 1.0 (OR = 1.06, 95% CI = 1.02–1.10) for every one degree day of increase in the integrated air temperature. The probability of an early peak exit count in weeks 6 to 8 stabilized to 0.80 to 0.95, when the integrated air temperature increased linearly from 210 to 264 degree days. The annual integrated air temperatures from January to March at 66.7% of 24 nursery roost sites in the U.K. from 2019–2023 ranged from 150–259 degree days, so prediction of early peak exit events could optimize nursery roost counts by addition of counts in weeks 6–8 at selected maternity roosts when the annual integrated air temperature ranged from 210–264 degree days and enable assessment of the extent and pace of climate change on P. pygmaeus.

This study examines the impact of habitat management on the seasonal and spatial activities of bat species in Mediterranean scrublands of southern France. Three study sites, presenting managed and unmanaged scrublands, were sampled by acoustic recording to assess their ecological potential for bat conservation. General linear mixed models (GLMMs) were used to identify the key factors driving variation in activity patterns of these areas. A total of 16 bat species were recorded, and no significant differences in taxonomic composition were found between managed and unmanaged areas. Bats have an opportunistic tendency to explore different habitats over long distances. In addition to the strong seasonal dynamics observed in most species, we found evidence of a shift in activity rhythms suggesting species adaptation to seasonal thermal variations and prey availability. In this study, the impact of managed areas on activity patterns depends on the functional traits of each species. Level of activity differed considerably from one species to another, suggesting that the 'management' effect is not the only ecological parameter involved in conditioning bats' preferred occupancy patterns.

The vespertilionid bat genus Hesperoptenus, comprising only five species and showing a distribution in the tropical regions from India to Sulawesi, was hitherto underrepresented in recent taxonomic studies. Here, modern cytogenetic techniques were applied to compare the karyotypes of two Hesperoptenus species, H. tomesi and H. blanfordi. Despite having the same chromosome number, 2n = 32, the karyotypes of H. tomesi and H. blanfordi were found to differ extensively. Instead, H. tomesi was found to share all nine derived Robertsonian fusion products with the previously published karyotype of H. doriae (2n = 26), which points to a closer relationship between both species. In line with our chromosomal data, mitochondrial DNA analyses also provided evidence for a closer relationship of H. tomesi with H. doriae and H. tickelli, for which no banded karyotype has been examined. Again, H. blanfordi was clearly separated from the remaining Hesperoptenus species. As a consequence, the subgenus Milithronycteris, comprising all species of Hesperoptenus except the type species H. doriae, is rendered paraphyletic. We therefore suggest to synonymize Milthronycteris with the subgenus Hesperoptenus. A chromosomal character, found in all three Hesperoptenus species examined but absent in other vespertilionid genera studied so far, namely a particular G-banding pattern on the homolog to Myotis chromosome MMY13, may serve as a synapomorphy for the genus Hesperoptenus.

Riparian ecosystems are valuable habitats for bats, due to high densities of emergent aquatic invertebrates that provide high-quality feeding areas. Throughout Europe, decline and extirpation of European beaver (Castor fiber) has been a key driver in the decline of the extent and quality of riparian habitat, and thus recolonisation has considerable potential to restore degraded areas. Previous research has shown that beaver-modified ecosystems can support more bats, but the assumed causal link (an increase in invertebrate prey) has not been tested. Here, we study bat activity and richness/abundance of aquatic macroinvertebrates at a site where free-roaming beavers have colonised naturally from a nearby (unofficial) release location versus a nearby control site with very similar hydrology and habitat matrix. Bat activity was recorded using walked activity transects and fixed-point acoustic detectors. Although bat species richness was similar, bat activity was substantially and significantly higher at the beaver site versus the control site overall (42.7%) and for four specific taxa: soprano pipistrelle (Pipistrellus pygmaeus; 8.4%), Daubenton's (Myotis daubentonii; 46.5%), common pipistrelle (Pipistrellus pipistrellus; 110.4%) and common noctule (Nyctalus noctula; 170.9%). Richness of the larvae/nymphs of emergent aquatic macroinvertebrate species known to form an important part of bat diet was 205.5% higher at the beaver site compared to the control site, while abundance was 817.4% higher. Overall bat activity was also linked to habitat (lotic > lentic), survey method (transect > fixed-point), and season (May–July peak). This is the first evidence of a likely causal link between beaver recolonisation and bat activity via an increase in abundance of key aquatic invertebrate prey and we recommended that benefits of beaver reintroduction on bats be considered in future feasibility studies.
