As biodiversity decreases worldwide, the development of effective techniques to track
changes in ecological communities becomes an urgent challenge. Together with other …

ABSTRACT The Acoustic Adaptation Hypothesis (AAH) posits that animal acoustic signals
used in long-range communication should be adapted to transmit well within the habitats in …

An animal's behavioral phenotype comprises several traits, which are hierarchically
structured in functional units. This is manifested in measured behaviors often being …

Biosemiotics to date has focused on the exchange of signals between organisms, in line
with bioacoustics; consideration of the wider acoustic environment as a semiotic medium is …

The emergence and maintenance of animal communication systems requires the co-
evolution of signal and receiver. Frogs and toads rely heavily on acoustic communication for …

Animal communication occurs in environments that affect the properties of signals as they
propagate from senders to receivers. We studied the geographic variation of the …

Intra-specific aggressive interactions play a prominent role in the life of many animals. While
studies have found evidence for repeatability in boldness, activity, and exploration in …

Territoriality has been widely described across many animal taxa, where the acquisition and
defence of a territory are critical for the fitness of an individual. Extensive evidence suggests …

Anuran males emit advertisement calls for the purpose of attracting females and repelling
conspecific males. Call transmission is influenced by the acoustics of the propagation …

Animal personality traits are sometimes linked to an individual's degree of plasticity, with
certain personality types being more plastic than others. In territorial species, consistently …
