“…Phyllostomid bats are also dominant in other Neotropical biomes (Gorrensen and Willig 2004;Stevens 2013). Among phyllostomids, we already expected that Sturnira lilium would be one of the most frequently captured bats in the study area, since Solanaceae, its main food-plants, are very abundant in the area (Muylaert et al 2013). We also captured the phyllostomid bats Pygoderma bilabiatum, Vampyressa pussilla, Chiroderma doriae, Sturnira tildae, and Uroderma bilobatum only in cerradão areas.…”

We studied bat assemblages in seven sampling sites in the rural zone of São Carlos, southeastern Brazil. The sampling sites were two riparian forests, two types of Brazilian savanna (cerrado sensu stricto and cerradão), a Pinus plantation, a semideciduous forest, and an open area. We sampled bats from January 2007 to December 2011 with mist nets, totalizing 100 capture nights and 38,587 m2h of capture effort. We captured 523 individual bats of 23 species belonging to three families. Sturnira lilium was the most frequently captured species and represented 40% of all captures, followed by Carollia perspicillata (17%) and Glossophaga soricina (12%). The studied heterogeneous landscape harbors a rich bat fauna compared to other studies with similar effort in well-preserved savannas.

“…These bats, however, are known to forage on the ground, where they feed on fallen fruits and occasionally are captured in rodent traps (Eisenberg & Redford, ; Muylaert et al. ). Further ecomorphological investigations of these species should focus on an improved crawling ability, not recorded in other stenodermatines studied so far (e.g.…”

Comparative morphology and scaling of the femur in yangochiropteran bats

Better known by their remarkable forelimb morphology, bats are also unique among mammals with respect to their hindlimbs. Their legs are rotated through 180°, generally reduced in size, and in some extant taxa particular bones (e.g. fibula) can even be absent. The femur is the main leg bone, but to date few bat studies have considered its morphology in detail, none in a wide-scale comparative study. Yangochiroptera is the largest bat taxon, spans nearly three orders of magnitude in body mass, and is highly diverse both in ecology and behavior, representing a good model for comparative analyses. Here, we describe the anatomy of the femur in a large sample of yangochiropteran bats (125 species, 70 genera, and 12 families), and explore major trends of morphological variation and scaling patterns in this bone. We used 13 categorical characters in the anatomical description and five linear dimensions in the quantitative analyses. Based on the categorical data, each family studied here was diagnosed, and those from the Neotropical region were included in an identification key. From the phylogenetic principal component analysis (pPCA) we showed that, in addition to size, major axes of variation in bat femur are related to robusticity and head morphology, features that are clearly distinct among some families. We also generated a phylomorphospace based on pPCA scores, highlighting convergences in femur shape. Molossidae, Mystacinidae, and Desmodontinae were grouped based on their greater robusticity, a pattern that was also recovered from categorical data. In these families, we found anatomical features (e.g. presence of tubercles and posterior ridges on the greater trochanter, long or medially/distally displaced lateral ridges on the shaft) that are well-known from their functional link with quadrupedal locomotion. Using phylogenetic regressions, we found out that compared with body mass, femur length scaled with negative allometry, as expected, but that femur width scaled isometrically, counter to expectations. As a result, robusticity index (the ratio of width to length), scaled with positive allometrylarger bats tended to have more robust hindlimbs. At species level, our most remarkable finding was related to Myotis simus, which presented the most robust femur (for its size) among yangochiropterans. Our results reinforce the informative potential of the chiropteran femur from both taxonomic and functional perspectives. Furthermore, the allometric trends seen in this bone may help understand the strategies adopted by flying vertebrates to deal with the high energetic cost of flight and, at the same time, evolve diversified foraging behaviors.

“…Compared with behavioural traits such as food selection, digestive capacity differs little among individual bats, only among bat species (Ayala‐Berdon et al. , Saldaña‐Vázquez & Schondube , Muylaert et al ). This trait is therefore more representative of dietary specialization among bat species and, in interaction with chiropterochoric plant diversity, could influence the structure of bat communities.…”

Frugivory is a feeding habit that evolved on two independent occasions in the order Chiroptera. In the Neotropical phyllostomid bats Carollia, Sturnira and Artibeus, this feeding habit has evolved to become specialized in the core plant taxa Piper, Solanum, and Ficus and Cecropia, respectively. I review the intrinsic factors that promote differences in diet among frugivorous bats of the genera Carollia, Sturnira and Artibeus and the interaction between these and extrinsic factors that affect bat community structure. The intrinsic factors are internal variables associated with fruit selection, body mass and nutrient digestibility that constrain the animals to exploit fruits with different morphological and nutritional characteristics. Intrinsic factors that explain frugivorous bat diet can thus drive community structure in frugivorous bats. The extrinsic factors that affect frugivorous bat community structure are associated with chiropterochoric plant phenology and composition, as well as with human activities that impact food availability. Nutritional diversity in chiropterochoric plants and the digestive capacity of frugivorous bats are key factors in understanding diet partitioning in Neotropical frugivorous bats. These factors are related to food availability and nutrition in bats and could be the major determinants of community structure of frugivorous bats in conserved and disturbed habitats.
