adaptive reasons, one must determine whether the preferred trait could have provided …

Papers on sexual selection often highlight the incredible diversity of sexually selected traits
across animals. Yet, few studies have tried to explain why this diversity evolved. Animals use …

There is a bewildering diversity of signals, sensory systems, and signaling behavior. A
consideration of how these traits affect each other's evolution explains some of this diversity …

Patterns of variation in the acoustic properties of advertisement calls of several species of
treefrogs (family Hylidae) are related to patterns of female preferences for these same …

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

Interest in the evolution of female mating preferences has increased greatly in recent years,
and numerous hypotheses have been proposed to explain how mating preferences evolve …

Territorial systems are characterized by the relative longevity and stability of interactions
between neighbouring individuals. Two abilities of signal receivers that can be seen as …

Octopamine has been called the 'fight or flight'hormone of insects. We tested this hypothesis
by measuring octopamine levels in the haemolymph of field crickets after fighting, flying …

The male-female interaction is an asymmetrical, usually obligate mutualism in which there
are conflicts of interest whenever multiple potential partners that vary in quality are available …

This book provides the reader with a perspective on current research into sound
communication in insects, with particular emphasis on the evolution of this method of …
