The field of bioacoustics is rapidly developing and characterized by diverse methodologies,
approaches and aims. For instance, bioacoustics encompasses studies on the perception of …

ABSTRACT The Acoustic Adaptation Hypothesis (AAH) predicts that acoustic signals
emitted at sites with greater vegetation density should have spectral and temporal …

Anurans emit advertisement calls with the purpose of attracting mates and repelling
conspecific competitors. The evolution of call traits is expected to be associated with the …

Zoologists have widely acknowledged the utility of classification systems for characterising
variation in anuran egg and clutch types, tadpole morphotypes, embryonic and tadpole …

Ambotuy Favoring males' specific sexual signals, female preferences play a major role in
frogs' evolutionary process by selecting traits linked to those signals. However, the factors …

Many animals produce long-distance acoustic signals to mediate a variety of social
interactions, and the efficacy of transmission depends in part on environmental attenuation …

Effective communication in birds is often hampered by background noise, with much
research focusing on the effect of anthropogenic noise on passerine bird song. Continuous …

Acoustic segregation is a way to reduce competition and allows for species coexistence
within anuran communities. Thus, separation in at least one acoustic niche dimension is …

Acoustic signals degrade and attenuate as they propagate through the environment, thus
transmitting information with lower efficiency. The acoustic adaptation hypothesis (AAH) …

The acoustic adaptation hypothesis (AAH) and ecological character displacement (ECD) are
two potential mechanisms shaping call evolution that can predict opposite trends for the …
