Animal communication systems have evolved so that individuals can make decisions based
upon the behaviour, physiology or morphology of others. Receiving mechanism s probably …

I analyze and summarize the empirical evidence supporting alternative hypotheses posed to
explain the evolution of rodent group-living. Eight hypotheses are considered: two rely on …

SYNOPSIS. Acoustic signals transmitted over large distances differ significantly from those
emitted by the signaler. Acoustic signals degrade in amplitude, spectral and temporal …

For optimal transfer of power to the surrounding medium, a sound source should have a
radius of 1/6 to 1/4 of the sound wavelength. Sound-waves propagate from the source as …

Sound recordings obtained from passive acoustic monitoring systems are increasingly used
to sample animal biodiversity. However, sound recorders sample variable detection spaces …

Any signal must get from a sender to a receiver if information is to be transmitted. In the case
of bird song, the acoustic properties of the habitat may hinder this being achieved. However …

While we may have always assumed that insects employ auditory communication, our
understanding of it has been impeded by various technical challenges. In comparison to the …

Publisher Summary The sounds produced by orthopteran insects are very diverse. They are
widely studied for the insight they give into acoustic behaviour and the biophysical aspects …

Individually distinctive vocalizations are ubiquitous; however, group distinctive calls have
rarely been demonstrated. Under some conditions, selection should favor calls indicating …

The efficiency of long-distance acoustic signalling of insects in their natural habitat is
constrained in several ways. Acoustic signals are not only subjected to changes imposed by …
