“…Upon capture, bats were identified in the field and released at the same location. We focused on bats of the family Phyllostomidae because mist nests are less effective for capturing bats from other families (Appel et al, 2022).…”

“…Species inventories, defined here as a comprehensive list of species detected in a specific geographic area, have provided a critical role as key response variable in biogeographical and community ecology studies, as well as in conservation planning (da Silva et al, 2012, 2014; Stevens, 2004, 2013; Stevens et al, 2007). Although methods for measuring species inventories typically vary with the biology of the taxon of interest (Appel et al, 2022; da Silva, 2010), it is virtually impossible to detect all species in a geographic area, especially in species‐rich assemblages with many rare species (Chao et al, 2009, 2020; Gotelli & Chao, 2013). Thus, understanding the required sample effort to estimate species richness and composition in a community can be valuable in establishing protocols for inventories and field surveys.…”

Here we assessed the efficacy of performing field surveys during both dry and rainy seasons to estimate species richness and composition of phyllostomid bats in 12 sites of the Brazilian Atlantic Forest. Our goal was to elucidate two opposite scenarios. If bat species compositions differ between the dry and rainy seasons, then field surveys in both seasons will be considered complementary for estimating local bat assemblages. In contrast, if bat species compositions in the dry season are a nested subset of the species present in the rainy season, then field surveys in both seasons will be considered redundant. Our results showed that field surveys performed only during the rainy season exhibited the same efficacy in recording bat species as field surveys considering both dry and rainy seasons combined. Consequently, the rare species sampled in the rainy season contributed to the uniqueness of communities in terms of species composition. Considering that time, funding, and the number of field personnel available for work are important factors when determining the sampling effort in highly biodiverse regions like the tropics, our results can be useful in establishing protocols for research projects with limited resources aiming to create a comprehensive list of species.

“…These searches returned a total of 203 studies, which were then filtered in two steps. First, we removed those studies that did not contain data on the Phyllostomidae family, as bats in this family are best sampled by mist nets (Kunz & Parsons, 2009), which is the most used method in bat studies in the Amazon biome (Appel et al, 2021). We only included studies that presented a species list with the intention of sampling the local species composition.…”

Aim:We evaluated the relative importance of geographical and environment variables for taxonomic, phylogenetic and functional β-diversity of phyllostomid bats along the entire Amazon biome and specifically in the lowlands.Location: Amazon biome.Taxon: Chiroptera. Methods:We carried out a bibliographic review and compiled a wide and unprecedented database of 106 phyllostomid bat species at 102 sites throughout the Amazon biome. For all possible pairs of sites in both datasets, we estimated the Jaccard pairwise dissimilarity, that is, β-diversity, considering its three dimensions-taxonomic, phylogenetic and functional-for its two components-turnover (substitution of species) and differences in species richness. The association between dissimilarity measurements and geographical and environment variables was assessed using multiple regressions on distance matrices (MRM). Results:We found that turnover and differences in species richness had similar contributions to the taxonomic β-diversity. However, for phylogenetic and functional β-diversity, lineages and functions richness differences contribute slightly more than

“…The study of bats in tropical regions has been restricted by limitations in sampling techniques. To fully sample a community and thus avoid biases in taxonomic and ecological coverage, bat surveys require a combination of survey methods (Appel et al, 2021)—a challenge that is amplified in species diverse tropical regions. Live‐capture methods (e.g.…”

1. Logging is the most widespread disturbance in tropical forests, altering ecological communities and functions. However, many species can persist in logged forests, particularly where disturbance is low. Despite a growing understanding of how logging affects wildlife, there remains little information for Southeast Asia's bats-in part due to major challenges in monitoring.2. We integrated remote sensing data from passive acoustic bat detectors with LiDAR-derived measures of forest structure from a human-modified landscape in Sabah, Borneo. Our appraisal of logging effects benefitted from a semi-automated classifier of bat calls that vastly speeds up the analysis of acoustic recording data.We recorded 105,576 bat passes from 21 phonic groups across a habitat disturbance gradient, comprising old-growth forest, repeatedly logged forest and tree plantations.3. We show that logging pressure (as depicted by changes to habitat quality, e.g. canopy height or shape) had negligible impact on the acoustic activity of bats. However, bat activity was higher in areas with a greater extent of high-biomass forest, as well as areas with greater topographical ruggedness. Logged forest supported higher levels of activity for several common bat phonic groups compared to old-growth forest. Across the landscape, plantations supported the lowest levels of bat activity, representing a threefold decrease compared to old-growth forest, and several species were not recorded in this habitat. 4. We found different call groups demonstrated different responses to forest disturbance. Sheath-tailed bats (Emballonura spp.) were active across all habitat types and were the most resilient to logging. Edge/open foragers were more prevalent in highly forested and topographically rugged areas. Horseshoe and leaf-nosed bats (flutter clutter foragers) demonstrated idiosyncratic responses to logging but were consistently absent from plantations.5. Synthesis and applications. Logged forests can provide an important refuge for many common bat species in Southeast Asia, but do not capture the full breadth of forest-specialist species. Nevertheless, logged forests provide substantially
