responses may be modulated by the scents in the environment.•We tested these predictions …

Communication sounds are ubiquitous in the animal kingdom, where they play a role in
advertising physiological states and/or socio-contextual scenarios. Human screams, for …

Many groups of vertebrates produce distress calls when attacked by predators as a last
attempt to survive. However, few studies investigate whether recognition of distress calls …

The pink fairy armadillo Chlamyphorus truncatus is the smallest extant armadillo and one of
the least‐known fossorial mammals. The aim of this study was to establish if its middle ear is …

Predatory interactions result in strong selection pressures acting on multiple aspects of
animal behaviour. Anti‐predator strategies are therefore common in most animals, typically …

Abstract Information contained in vocal signals can include a caller's individual identity,
which can be potentially used for individual recognition. Individual recognition at a distance …

Birds often vocalize when threatened or captured by a predator. We present detailed
qualitative analyses of calls from 24 red-capped plover (Charadrius ruficapillus) and 117 …

Distress vocalizations are emitted by animals experiencing extreme physical distress, such
as when caught by a predator. These signals are emitted by numerous and phylogenetically …

Background The rutting vocal display of male impala Aepyceros melampus is unique for its
complexity among ruminants. This study investigates bouts of rutting calls produced towards …

Although communication capabilities are displayed by many vertebrate groups, some
repertoires are poorly known, such as the case of xenarthrans, particularly armadillos, for …
