Research on animal signaling enhances our understanding of links between sensory
processing, decision making, behavior, and evolution. Studies of sexually-selected signals …

A long-standing goal for biologists has been to understand how female preferences operate
in systems where males have evolved numerous sexually selected traits. Jumping spiders of …

Complex courtship signals can be dissected into distinct components that can either function
independently or via interactions with one another. Male Rabidosa rabida wolf spiders use …

In many animals, males display colorful ornaments to females during courtship, the
effectiveness of which depends on the ambient lighting environment. While a variety of …

Many animals communicate using multiple sensory channels simultaneously and this ability
enables them to overcome the challenges of living in variable environments. Studies of wolf …

A broad understanding of multimodal courtship function necessitates knowledge of the
potential information content of signal components, the efficacy of signal components in …

Recently, work has shown that multimodal communication is common throughout the animal
kingdom but the function of multimodal signals is still poorly understood. Phidippus clarus …

In many animals, males display costly, condition-dependent ornaments to choosy females.
Indicator models of sexual selection predict that females should choose mates based on …

Differences between males and females can evolve through a variety of mechanisms,
including sexual and ecological selection. Because coloration is evolutionarily labile …

Identifying the various factors that influence complex signal evolution is a difficult task, yet it
is fundamental to understanding the evolution of animal communication. Here we explore …
