“…The rarefaction/extrapolation for q = 0 clearly shows a progressive decline in richness along the elevational gradient (see Supporting Information Appendix S2), despite the convergence to a similar level of richness in the three lowest bands as the sample size increases. This is probably due to an infrequent presence in elevated areas of species that are mostly present at low elevation; the small distances that separate low and high elevation in these mountain ranges can be easily covered by bats for long‐distance dispersal (Esbérard, Godoy, Renovato, & Carvalho, ) or on foraging trips (Mello et al., ).…”

Aim:This study aims to contribute to the identification of ecological determinants of tropical moist forest montane biodiversity, analysing changes in the structure of bat assemblages along an elevational gradient and testing the role of species traits shaping those assemblages.Location: Mountain ranges in the Brazilian Atlantic Forest. Methods:We compiled a dataset with the composition of phyllostomid bat assemblages at 32 forested sites, ranging from 60 m to 1,960 m a.s.l. We quantified how abundance and diversity changed along this elevational gradient, and assessed the capacity of each species to be present and abundant at each elevation, identifying traits that may influence that capacity.Results: Abundance and species diversity declined markedly with increasing elevation. Tolerance to low temperatures, low habitat specialization and cave roosting facilitated success at higher elevations. Owing to trait filtering, and to changes in resource availability with elevation, assemblages were progressively dominated by a smaller number of mostly generalist species as elevation increased. Higher elevations harbour only a subset of the species that are present in the lowland forest, with no mountain specialized species. Main conclusions:High mountains harbour phyllostomid assemblages that are impoverished subsets of those at lower elevations. Phyllostomids have a tropical origin and may thus have a low potential to adapt to montane forest environments, which possibly explains the observed climatic trait filtering. Habitat filtering is also important, keeping forest specialists mostly at lowest elevations. Protected areas in the Atlantic Forest are mostly limited to mountains. While these areas are clearly important to protect biodiversity, including phyllostomid assemblages, it is now critical to protect and restore the few remnants of lower elevation Atlantic Forest where higher productivity and resource levels, increased complexity of vertical structure, and fewer climatic constraints favour the success of a wider range of phyllostomid bat species of tropical origin.

“…Other studies show the opposite effect in non-flying mammals, bats, birds, and trees (Galindo-González & Sosa 2003;Cleary et al 2016;Socolar et al 2019;Pardo et al 2019) . The lack of a significant effect of distance to conserved habitats on bat abundance in disturbed habitats may be related to the variation in habitat disturbance type in our study and the ability of phyllostomids to fly large distances either to migrate or forage (Arnone et al 2016;Esbérard et al 2017;Medellin et al 2018) . In order to determine the effect of these two variables on bat abundance in disturbed habitats, studies that evaluate the effects of habitat disturbance on bat abundance comparing disturbance type and phyllsotomid vagility are necessary.…”

The loss of tropical forest cover caused by land-use change is causing a reduction in functional groups, such as trophic guilds. Phyllostomid bats (family Phyllostomidae) are essential in the Neotropics since they occupy up to six trophic guilds, and are pollinators, seed dispersers, and regulators of vertebrate and invertebrate populations. In this study, a series of meta-analyses were performed in order to analyse their response to habitat disturbance. Data were obtained through a comprehensive literature review whereby we measured the abundance of phyllostomid bats in disturbed habitats and conserved forests. We found that the abundance of phytophagous bats depends on the type of habitat disturbance and the type of forest where it occurs. On the other hand, animal-feeding bats reduce their abundance in any disturbed habitat regardless of disturbance type and forest type. No phylogenetic signal was found in the response of bats to habitat disturbance, nor was the response found to be dependent on the type of crop, the age of the secondary forest, or the distance to a conserved forest. These results demonstrate that feeding and the type of forest where the disturbance occurs are important aspects to understand the reduction of animal populations in the face of habitat destruction processes. This has implications on the conservation of species and their function in ecosystems.HighlightsNo phylogenetic signal was found in the abundance of bats in disturbed habitats.The abundance of bats in disturbed habitats depends on the trophic guild.Forest altitude influences the abundance of bats in disturbed habitats.Animal-feeding bats reduced their abundance in disturbed habitats regardless of disturbance type and forest type.

“…Indeed, bats exhibit frequent mid‐ to long‐distance dispersal events that integrate different communities, especially in the highly fragmented Atlantic Forest (Arnone, Trajano, Pulcherio‐Leite, & Passos, 2016; Bianconi, Mikich, & Pedro, 2006; Mendes, Vieira, Oprea, & Ditchfield, 2009). For example, Artibeus lituratus , Sturnira lilium and Platyrrhinus lineatus have been recorded to move 85, 79 and 120 km, respectively, between communities (Esberard et al., 2017). These are some of the most numerous bats in the Atlantic Forest, suggesting that such integrative movements are common.…”

“…Dispersal distances for such free‐ranging and mobile organisms are difficult to capture and thus such findings are rare and certainly dispersal distances are underestimated. Nonetheless, Neotropical bats have been reported to disperse at least hundreds of kilometres (Esberard, Godoy, Renovato, & Carvalho, 2017). Neotropical bats exhibit extensive, hemispheric gradients in biodiversity characterized not only by species richness (Willig & Lyons, 1998; Willig & Selcer, 1989) but also functional (Stevens, Cox, Strauss, & Willig, 2003), trait (Stevens, Willig, & Strauss, 2006) and phylogenetic (Stevens, Tello, & Gavilanez, 2013) dimensions of biodiversity as well as patterns of taxonomic (Villalobos & Arita, 2010) and phylogenetic diversity fields (Villalobos, Rangel, & Diniz‐Filho, 2013).…”

Aim: Spatial patterns of local species composition are shaped by dispersal ability. Here we examine the effects of dispersal ability on metacommunity structure of bats throughout the Atlantic Forest of South America considering differences among communities, functional groups and species regarding environmental, spatial and connectivity-related drivers of composition. We also examined phylogenetic and ecological correlates, such as incidence (i.e. frequency of occurrence across sites) and wing morphology, of the degree to which species respond to spatial and environmental drivers. Location: Atlantic Forest of Argentina, Brazil and Paraguay. Taxon: Phyllostomid bats. Methods: Data from the Atlantic Bats dataset were compiled for 39 species at 120 sites. Variation was partitioned into pure environmental, pure space, pure connectivity, joint and unaccounted variation fractions. Redundancy analyses or linear regression determined amount of variation in variation fractions that was accounted for by phylogeny or ecological characteristics of species. Results: The metacommunity of Atlantic Forest phyllostomid bats was significantly structured by environmental, space and connectivity characteristics. Animalivore, nectarivores and sanguinivore species composition was significantly related only to connectivity. Frugivores exhibited structure that was significantly related to all three kinds of characteristics (pure environmental, pure spatial and pure connectivity) and similar to that of the overall metacommunity. Species-specific responses to environmental, spatial and connectivity drivers were variable but exhibited strong affinities related to phylogeny and functional group. As incidence of a species increased, variation in distribution and abundance was more related to environmental characteristics. There was no significant relationship between forearm length and magnitude of the connectivity variation partition. Main Conclusions: Metacommunity structure of bats in the Atlantic Forest is complex and includes variation across multiple scales of ecological organization. Structure is strongly associated with phylogenetic, functional and distributional characteristics of species, with these, in turn, related to responses to spatial and environmental gradients in the Atlantic Forest.
