“…Probably these unsuitable characteristics are what force the species to move to other sites. In addition, it is known that Mormopids have a preference for shelters with temperatures higher than 30 °C in other roosts (Rezsutek & Cameron, 1993;Ávila-Flores & Medellín, 2004;Torres-Flores & Santos-Moreno, 2017;Ayala-Téllez, Iñiguez-Dávalos, Olvera-Vargas, Vargas-Contreras, & Herrera-Lizaola, 2018). Maximum temperatures are not higher than 27 °C in any of the shelters observed in this study.…”

Introduction: Reproduction is a critical phase for most living organisms and in bats the reproductive strategies exhibit considerable complexity and variability. Objective: To describe the reproductive patterns and population dynamics of seven bat species (Artibeus toltecus, Carollia perspicillata, Glossophaga soricina, Mormoops megalophylla, Pteronotus fulvus, Pteronotus mesoamericanus and Natalus mexicanus) that roost in one mine (La Mina) and two caves (El Apanguito and Cerro Huatulco) in the State of Oaxaca, in Southeastern México. Methods: Sampling was conducted monthly from July 2016 to June 2017. Bats were captured using a harp trap, which was placed at the entrance of the roosts. The captured bats were identified using taxonomic keys, marked with an aluminum ring, sex and age class were also determined. Reproductive activity was modeled through 63 GLMs for each species (504 in total). The best model was selected according to the Akaike Information Criterion (AIC). Results: A total of 5 836 bats were captured and marked, classified into 14 species, 10 genera, and five families. The most abundant species were: P. fulvus and P. mesoamericanus, representing 41 % and 32.3 % of the captures, respectively. The mormopids M. megalophylla, P. fulvus, P. mesoamericanus, together with N. mexicanus showed a restricted seasonal monoestrous pattern, while the phyllostomids A. toltecus, C. perspicillata, and G. soricina showed a seasonal bimodal polyoestry pattern. The monthly abundance of species fluctuated significantly (H= 13, df= 11, P= 0.044) in the three roosts throughout the entire study period and the best supported GLM that included the seven species showed that the six chosen variables (season, sex, roost, temperature, precipitation and humidity) were positively associated with reproductive activity. Conclusions: The reproductive activity of each species seems to be synchronized with the end of the dry season and the beginning of the rainy season, as well as influenced by factors such as temperature, humidity and roost site.

“…These environments tend to be more stable and have the optimal structural and microclimatic conditions (temperature and humidity) required by several species (Fenton et al., 1994; Furey & Racey, 2015). Cohabitation by different bat species is common in caves, and some caves may harbour very high richness, sometimes surpassing 20 species (Barros et al., 2021; Torres‐Flores & Santos‐Moreno, 2017).…”

Species richness, occurrence and rarity of bats in Brazilian caves

Caves are among the most important roosts of hundreds of bat species worldwide. However, caves can be formed in different lithologies. Cave structure and characteristics, which are shaped by lithology, can, in turn, influence roost preferences for different bat species. Therefore, cave lithology and characteristics can help us to better understand why some bat species may be rare in some caves and common in others. Brazil is a continental country, rich in bat species (181 spp.), lithologies and caves (>23 000). However, only a small fraction of the known caves has been sampled for bats so far, with no emphasis on the role lithology may have. Based on a literature review and using data on bat occurrence, in this study, we investigated the influence of lithology on bat species richness and rarity in Brazilian caves. We evaluated 117 studies, including data from 552 caves, and updated the number of bat species occurring in Brazilian caves to 81. Species richness differed between lithologies: carbonate caves had higher species richness, whereas iron caves had lower species richness. Richness was positively related to carbonate caves and with cave size: the bigger the cave, the more species‐rich it tends to be. Overall, caves in the Cerrado had the highest species richness, followed by Atlantic Forest, Caatinga caves and Amazonian caves. Thirteen species can be considered as primarily cave‐dwelling species, recorded in 10%–20% of the caves. Rarity was common among primarily cave‐dwelling species. Nearly 22% of the sampled caves harboured endangered species, reaching 53% of the species‐richest caves. Our analysis provides a comprehensive baseline for bat fauna in different types of caves in Brazil. Even so, we strongly recommend the establishment of long‐term monitoring of population trends for bats in Brazilian caves, which is necessary information but almost non‐existing for the country.

“…Unprotected karst is especially susceptible to destruction, with an average loss of around 5.7% of area annually due to mining and other uses [35][36][37] . This loss of cave habitat is coupled with unregulated hunting and tourism, and foraging habitat loss; therefore understanding the impacts of these factors on the population status of bats and biotically important caves are urgently needed 23,30,38,39 . It is estimated that at least 50% of global bat species are dependent on caves 23 but the degree of threat to bat cave communities and prioritisation has never been analysed across large scales 30 .…”

Research and conservation interventions are disproportionately focused on taxa perceived as charismatic, while other systems with high levels of endemism, and often under-protected such as caves and subterranean ecosystems remain neglected. Bats are keystone to cave ecosystems making them ideal surrogates to understand diversity patterns and assay conservation priorities. Using a novel framework, we assessed and mapped the global bat cave vulnerabilities and priorities at the biome and site level. Almost half (N = 678, 48%) of bat species across the world regularly use caves, with 32% endemic to a single country, and 15% currently threatened with extinction. Tropical realms and small-ranged species faced the highest levels of risk. Our analyses consistently showed that most caves with lower threat levels show higher cave biotic potential (i.e., evolutionary distinctiveness and endemism), though this may be due to the loss of species from more disturbed caves. We estimate that 3% to 28% are high-priority caves for conservation in broad-scale (biome level) and fine-scale (site-dependent) analyses respectively. Amongst regions, the highest concentration of conservation priority areas are in the Palearctic and tropical regions (except Afrotropical), which requires more intensive data sampling. Our results further highlight the importance of prioritising bat caves at local scales but show that broader scale analysis is possible if robust cave data is present and effective parameters are included (i.e., appropriate landscape features and threats). Developing priorities for these systems requires more systematic approaches as a standard measure to develop the priorities needed to maintain cave diversity.
