Animals that communicate by means of acoustic signals show diverse strategies in the presence of noise interference. Penna et al. (2005, Animal Behaviour, 70, 639e651) found that the leptodactylid frog Eupsophus calcaratus ...

The underground environment poses particular communication challenges for subterranean rodents. Some loud and low-pitched acoustic signals that can travel long distances are appropriate for long-range underground communication ...

Animals using sound communication have developed different strategies to overcome noise interference, but studies have rarely examined animals behaving in their natural environments. Males of the leptodactylid frog Eupsophus ...

Unlike humans, who communicate in frequency bands between 250 Hz and 6 kHz, rats can communicate in frequencies above 18 kHz. Their vocalization types depend on the context and are normally associated to subjective or ...

Cetaceans produce a variety of vocalizations to communicate; however, little information exists on the acoustic behavior displayed by Commerson?s dolphins (Cephalorhynchus commersonii) in the wild other than their echolocation ...

The Antillean manatee (Trichechus manatus manatus) is an endangered marine mammal that inhabits the Caribbean Sea and riverine systems in Central America. Their acoustic behavior is relevant for individual identification, ...
