Tolerance of Placozoa for temperate climates: Evidence for known and new placozoan clades in the southern waters of Australia Open
Placozoans are small multicellular sea-dwelling animals that are typically found in shallow, warm ocean waters and have been reported in various marine environments worldwide. Their unique morphology makes them a powerful new model organis…

Interplay of diet and sympatry in the morphological evolution of noctilionoid bats Open
Aim The remarkable ecomorphological diversity of the bat superfamily Noctilionoidea is the result of a diet‐mediated adaptive radiation. Stemming from a putatively insectivorous ancestor, noctilionoid bats diversified to adapt to the wides…

Bats learn about potential food sources from others: a review Open
Compared to trial-and-error learning, learning from others is often a viable means of adding new adaptive behaviours to an individual’s repertoire. This is especially true in long-lived, group-living species that encounter moderate levels …

Unique near isometric ontogeny in the pterosaur <i>Rhamphorhynchus</i> suggests hatchlings could fly Open
Rhamphorhynchus muensteri is one of the best-known flying reptiles, represented by >130 well-preserved fossil specimens, from hatchlings to full adults. The life history of this pterosaur remains controversial as to when in ontogeny they t…

The influence of bat ecology on viral diversity and reservoir status Open
Repeated emergence of zoonotic viruses from bat reservoirs into human populations demands predictive approaches to preemptively identify virus‐carrying bat species. Here, we use machine learning to examine drivers of viral diversity in bat…

Molecular diet analysis finds an insectivorous desert bat community dominated by resource sharing despite diverse echolocation and foraging strategies Open
Interspecific differences in traits can alter the relative niche use of species within the same environment. Bats provide an excellent model to study niche use because they use a wide variety of behavioral, acoustic, and morphological trai…

Phylogeny matters: revisiting ‘a comparison of bats and rodents as reservoirs of zoonotic viruses’ Open
Diseases emerging from wildlife have been the source of many major human outbreaks. Predicting key sources of these outbreaks requires an understanding of the factors that explain pathogen diversity in reservoir species. Comparative method…

Male and female bats differ in their use of a large urban park Open
Understanding how wildlife respond to ever-encroaching urbanization is of great concern. Bats are the second-most speciose mammalian order and while many appear to be urban adapted, we currently have a limited understanding of their demogr…

Sonar strobe groups and buzzes are produced before powered flight is achieved in the juvenile big brown bat, <i>Eptesicus fuscus</i> Open
Laryngeally echolocating bats produce a rapid succession of echolocation calls just before landing. These landing buzzes exhibit an increase in call rate and decreases in call peak frequency and duration relative to pre-buzz calls and rese…

A method for rapid testing of social learning in vampire bats Open
Designing experiments on social learning using an untested behaviour or species requires baseline knowledge of how the animals will perform. We conducted a pilot study of a procedure for rapidly testing social learning in the highly social…

Younger vampire bats (Desmodus rotundus) are more likely than adults to explore novel objects Open
The effects of age on neophobia and exploration are best described in birds and primates, and broader comparisons require reports from other taxa. Here we present data showing age-dependent exploration in a long-lived social species, the c…

Don’t believe the mike: behavioural, directional, and environmental impacts on recorded bat echolocation call measures Open
Echolocation calls produced by bats in their larynges allow these flying, nocturnal mammals to orient and find food at night. The acoustic signals are not like bird song, and even individual bats exhibit great flexibility in call design an…

Bats without borders: Predators learn novel prey cues from other predatory species Open
Bats learn about novel acoustic prey cues as quickly from heterospecifics as from conspecifics.

Fungus Causing White-Nose Syndrome in Bats Accumulates Genetic Variability in North America with No Sign of Recombination Open
Since its discovery in 2006, the emerging infectious disease known as white-nose syndrome has killed millions of bats in North America, making it one of the most devastating wildlife epidemics in recorded history. We demonstrate that there…

Oilbirds produce echolocation signals beyond their best hearing range and adjust signal design to natural light conditions Open
Oilbirds are active at night, foraging for fruits using keen olfaction and extremely light-sensitive eyes, and echolocate as they leave and return to their cavernous roosts. We recorded the echolocation behaviour of wild oilbirds using a m…

Body Size Predicts Echolocation Call Peak Frequency Better than Gape Height in Vespertilionid Bats Open
In most vocalizing vertebrates, lighter animals tend to produce acoustic signals of higher frequency than heavier animals. Two hypotheses propose to explain this negative relationship in vespertilionid bats: (i) mass-signal frequency allom…
