Data from: Phylogenetic community structure of North American desert bats: influence of environment at multiple spatial and taxonomic scales

Lorelei E. Patrick & Richard D. Stevens
1. Numerous processes influence community structure. The relative importance of these processes are thought to vary with spatial, temporal, and taxonomic scale: density dependent interactions are thought to be most influential at small scales, at intermediate scales environmental conditions may be the most influential factor, and biogeographic processes are thought to be of greater importance at larger scales. Additionally, the stress-dominance hypothesis suggests that communities experiencing harsher environmental conditions will be predominantly structured by habitat...

Data from: Resource availability and roosting ecology shape reproductive phenology of rain forest insectivorous bats

Elias Nurul-Ain, Rosli Hashim, Tigga Kingston & Hashim Rosli
Bats in temperate and subtropical regions typically synchronize birth of a single young with peaks in resource availability driven by local climate patterns. In tropical rain forest, insects are available throughout the year, potentially allowing departures from seasonal monoestry. However, reproductive energy budgets may be constrained by the cost of commuting to foraging grounds from distant roosts. To test these hypotheses, we simultaneously tracked female reproductive activity of 11 insectivorous bat species, insect biomass, and...

Data from: Threshold effect of habitat loss on bat richness in cerrado-forest landscapes

Renata L. Muylaert, Richard D. Stevens & Milton C. Ribeiro
Understanding how animal groups respond to contemporary habitat loss and fragmentation is essential for development of strategies for species conservation. Until now, there has been no consensus about how landscape degradation affects the diversity and distribution of Neotropical bats. Some studies demonstrate population declines and species loss in impacted areas, although the magnitude and generality of these effects on bat community structure are unclear. Empirical fragmentation thresholds predict an accentuated drop in biodiversity, and species...

Data from: Taxonomic and phylogenetic determinants of functional composition of Bolivian bat assemblages

Luis F. Aguirre, Flavia A. Montaño-Centellas, M. Mercedes Gavilanez, Richard D. Stevens, Luis Acosta, Marcos F. Terán, M. Gabriela Flores-Saldaña & Aideé Vargas
Understanding diversity patterns and the potential mechanisms driving them is a fundamental goal in ecology. Examination of different dimensions of biodiversity can provide insights into the relative importance of different processes acting upon biotas to shape communities. Unfortunately, patterns of diversity are still poorly understood in hyper-diverse tropical countries. Here, we assess spatial variation of taxonomic, functional and phylogenetic diversity of bat assemblages in one of the least studied Neotropical countries, Bolivia, and determine whether...

Data from: Fossil evidence of the avian vocal organ from the Mesozoic

Julia A. Clarke, Sankar Chatterjee, Zhiheng Li, Tobias Riede, Federico Angolin, Franz Goller, Marcelo P. Isasi, Daniel R. Martinioni, Francisco J. Mussel & Fernando E. Novas
From complex songs to simple honks, birds produce sounds using a unique vocal organ called the syrinx1, 2. Located close to the heart at the tracheobronchial junction, vocal folds or membranes attached to modified mineralized rings vibrate to produce sound1, 2, 3, 4, 5, 6, 7. Syringeal components were not thought to commonly enter the fossil record6, and the few reported fossilized parts of the syrinx are geologically young8, 9, 10, 11 (from the Pleistocene...

Data from: Is there a correlation between abundance and environmental suitability derived from ecological niche modelling? A meta-analysis

Marcelo M. Weber, Richard D. Stevens, José Alexandre F. Diniz-Filho & Carlos Eduardo V. Grelle
It is thought that species abundance is correlated with environmental suitability and that environmental variables, scale, and type of model fitting can confound this relationship. We performed a meta-analysis to (i) test whether species abundance is positively correlated with environmental suitability derived from correlative ecological niche models (ENM), (ii) test whether studies encompassing large areas within a species range (>50%) exhibited higher AS correlations than studies encompassing small areas within a species range (<50%), (iii)...

Data from: Efficacy of a probiotic bacterium to treat bats affected by the disease white-nose syndrome

Tina L. Cheng, Heather Mayberry, Liam P. McGuire, Joseph R. Hoyt, Kate E. Langwig, Hung Nguyen, Katy L. Parise, Jeffrey T. Foster, Craig K. R. Willis, Auston Marm Kilpatrick & Winifred F. Frick
The management of infectious diseases is an important conservation concern for a growing number of wildlife species. However, effective disease control in wildlife is challenging because feasible management options are often lacking. White-nose syndrome (WNS) is an infectious disease of hibernating bats that currently threatens several North American species with extinction. Currently, no effective treatments exist for WNS. We conducted a laboratory experiment to test the efficacy of treatment with Pseudomonas fluorescens, a bacterium that...
