... costs. To date, however, no studies have gauged whether there are significant energetic costs to social call production in bats, which heavily rely on acoustic communication for a diversity of social tasks. We measured energetic expenditure during acoustic signaling in Spix's disc-winged bats...

...Alyson F. Brokaw; Michael Smotherman ABSTRACT Many studies have characterized olfactory-tracking behaviors in animals, and it has been proposed that search strategies may be generalizable across a wide range of species. Olfaction is important for fruit- and nectar-feeding bats, but it is uncertain...

...Peter A. Wagenhäuser; Lutz Wiegrebe; A. Leonie Baier ABSTRACT Many echolocating bats forage close to vegetation – a chaotic arrangement of prey and foliage where multiple targets are positioned behind one another. Bats excel at determining distance: they measure the delay between the outgoing call...

... premaxilla bones of the upper jaw develop abnormally. However, ∼50% of bat species have natural, non-pathological cleft palates. We used the family Vespertilionidae as a model and linear and geometric morphometrics within a phylogenetic framework to (1) explore evolutionary patterns in cleft morphology, and...

Pre-hibernating noctule bats that were fed 13 C-enriched linoleic acid (LA) showed 12 times higher tracer oxidation rates compared with conspecifics fed 13 C-enriched palmitic acid (PA). After this experiment, we supplemented the...
