Data from: Habitat suitability and connectivity modeling reveal priority areas for Indiana bat (Myotis sodalis) conservation in a complex habitat mosaic
Context <p>Conservation for the Indiana bat (<i>Myotis sodalis), </i>a federally endangered species in the United States of America, is typically focused on local maternity sites; however, the species is a regional migrant, interacting with the environment at multiple spatial scales. Hierarchical levels of management may be necessary, but we have limited knowledge of landscape-level ecology, distribution, and connectivity of suitable areas in complex landscapes.</p> Objectives <p>We sought to 1) identify factors influencing <i>M. sodalis </i>maternity colony distribution in a mosaic landscape, 2) map suitable maternity habitat, and 3) quantify connectivity importance of patches.</p> Methods <p>Using 3 decades of occurrence data, we tested <i>a priori</i>,<i> </i>hypothesis-driven<i> </i>habitat suitability models. We mapped suitable areas and quantified connectivity importance of habitat patches with probabilistic habitat availability metrics.</p> Results <p>Factors improving landscape-scale suitability included limited agriculture, more forest cover, forest edge, proximity to medium-sized water bodies, lower elevations, and limited urban development. Areas closer to hibernacula and rivers were suitable. Binary maps showed that thirty percent of the study area was suitable for <i>M. sodalis</i> and 29% was important for connectivity. Most suitable patches were important for intra-patch connectivity and far fewer contributed to inter-patch connectivity.</p> Conclusions <p>While simple models may be effective for small, homogenous landscapes, complex models are needed to explain habitat suitability in large, mixed landscapes. Suitability modeling identified factors that made sites attractive as maternity areas. Connectivity analysis improved our understanding of important areas for bats, identified suitable patches that may be isolated from the habitat network, and prioritized areas to target restoration.</p>
Data from: Loss of sweet taste despite the conservation of sweet receptor genes in insectivorous bats
<p>The evolution of taste perception is usually associated with the ecology and dietary changes of organisms. However, mismatches between feeding ecology and taste receptor evolution have been identified in some vertebrate animals. One example is the sweet taste receptor gene <em>Tas1r2</em>. Previous analysis of partial sequences has revealed that <em>Tas1r2</em> has undergone equally strong purifying selection between insectivorous and frugivorous bats. To test whether the sweet taste function is also important in bats with contrasting diets, we examined the complete coding sequences of both sweet taste receptor genes (<em>Tas1r2</em> and <em>Tas1r3</em>) in 34 representative bat species. Although these two genes are highly conserved between frugivorous and insectivorous bats at the sequence level, our behavioral experiments revealed that an insectivorous bat (<em>Myotis ricketti</em>) showed no preference for natural sugars, whereas the frugivorous species (<em>Rousettus leschenaultii</em>) showed strong preferences for sucrose and fructose. Furthermore, while both sweet taste receptor genes are expressed in the taste tissue of insectivorous and frugivorous bats, our cell-based assays revealed striking functional divergence: the sweet taste receptors of frugivorous bats are able to respond to natural sugars whereas those of insectivorous bats are not, which is consistent with the behavioral preference tests, suggesting that functional evolution of sweet taste receptors is closely related to diet. This comprehensive study suggests that using sequence conservation alone could be misleading in inferring protein and physiological function, and highlights the power of combining behavioral experiments, expression analysis, and functional assays in molecular evolutionary studies. </p>
Data from: Development of conserved microsatellite markers of high cross-species utility in bat species (Vespertilionidae, Chiroptera, Mammalia)
Comparative ecological and behavioural studies of the widespread and diverse Vespertilionidae, which comprise almost 400 of the 1,100 bat species, have been limited by the availability of markers. The potential of new methods for developing conserved microsatellite markers which possess enhanced cross-species utility has recently been illustrated in studies of birds. We have applied these methods to develop enhanced microsatellite markers for vespertilionid bats, in particular for the genus Myotis (103 species). We compared published bat microsatellites with their homologs in the genome sequence of the little brown bat, Myotis lucifugus to create consensus sequences which were used to design candidate primer sets. Primer sets were then tested for amplification and polymorphism in 22 species of bat from nine of the largest families (including 11 Vespertilionidae). Of 46 loci tested, 33 were polymorphic, on average, for each of seven Myotis species tested, 20 in each of four non-Myotis vespertilionid species, and two in 11 non-vespertilionid species.

Figure 4 Caves of El Peñon are located riverside of Río Ulúa. This agglomeration of 7 caves is located riverside of the Río Ulúa. During the surveys we found an owl (Strigidae) coming out of the cave when the activity of the bats (18:00) started, and also, we found remains of the food belonging to a presumably Chironectesminimus (Didelphidae), that use rocks of these caves to eat fishes. The photos were taken by Hefer Ávila.

Figure 2 Species richness of bats in Ceguaca, Santa Bárbara based on the abundance of individuals captured during 2015 and 2016. Based on the estimator indexes, between 35.05 and 58.29% of bat species are still unrecorded. None of these accumulation curves reached an asymptote, which reflects that more sampling effort is needed in the area.
