Animals engage in complex social encounters that influence social groups and resource
allocation. During these encounters, acoustic signals, used at both short and long ranges …

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 …

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 …

Sexual selection can result in extreme development of multimodal mate-attracting traits,
including complex constructions. Male Great Bowerbirds build bowers for attracting females …

Highlights•Tropical crickets use anthropogenic objects as calling sites.•Males calling on
anthropogenic objects show a considerably increased sound amplitude.•Louder calls lead …

The development of road infrastructures causes the loss and fragmentation of natural
habitats, structurally, due to the landscape reconfiguration, and functionally, due to the noise …

The effective production of acoustic signals is critically important for intraspecific
communication in vocal animals; however, it is also highly time-consuming, energetically …

Animals choosing particular display sites often balance sexual and natural selection
pressures. Here we assess how physical properties of display sites can alter this balance by …

Advertisement calls are emitted by anuran males to attract females or repel competitors. Call
frequencies are coupled with the vocal apparatus and, thus, likely with body size due to …

Monoaminergic neurotransmitters are essential for a multitude of physiological and
behavioral functions including territoriality and parental care. The Puerto Rican coquí frog …
