While bird vocalizations (produced by the syrinx) have been the focus of countless studies, mechanical sounds (produced by external body structures) have received much less attention. In particular, the evolutionary interplay ...

Time reversal of acoustic waves can be achieved efficiently by the persistent control of excitations in a finite region of the system. The procedure, called Time Reversal Mirror, is stable against the inhomogeneities of ...

Animal communication is a key feature of intra- and inter-specific interactions in nature. Vocalizations and plumage coloration are two of the most exploited signaling pathways among birds and they have an important role ...

© 2014 Elsevier Ltd.Geographic variation of traits may represent the first step for evolutionary divergence potentially leading to speciation. Signals are behavioral traits of particular interest for the study of variation ...

Propagation patterns of animal acoustic signals provide insights into the evolution of signal design to convey signalers information to potential recipients. However, propagation properties of vertebrate calls have been ...

Vocalization is one of the major means of communication in animal groups and is crucial in anuran mate recognition. Animal calls consist of spectral and temporal parameters, whose evolution can be influenced by environmental ...
