The question of how new species evolve has been examined at every level, from
macroevolutionary patterns of diversification to molecular population genetic analyses of …

Male secondary sexual traits are one of the most striking and diverse features of the animal
kingdom. While these traits are often thought to evolve via sexual selection, many questions …

Courtship songs have undergone a spectacular diversification in the Drosophila buzzatii
cluster. Accordingly, it has been suggested that sexual selection has played a significant …

Abstract Changes in elements of courtship behaviour can influence sexual isolation
between species. Large‐scale analyses of changes, including loss and gain of courtship …

Populations may become isolated by distance, geographic barriers or both. Isolated
populations often diverge in behavioral, morphological and genetic traits as a result of …

Acoustic signals play an important role in premating isolation based on sexual selection
within many taxa. Many male parasitic wasps produce characteristic courtship songs used …

Closely related species often differ in the signals involved in sexual communication and
mate recognition. Determining the factors influencing signal quality (ie signal's content and …

Aggression is a key determinant of fitness in many species, mediating access to mates, food,
and breeding sites. Variation in intrasexual aggression across species is likely driven by …

A wide spectrum of song complexity has been documented in a broad range of animal taxa.
However, the underlying processes sha** acoustic differences are still poorly understood …

Populations may become isolated by distance, geographic barriers or both. Isolated
populations often diverge in behavioral, morphological and genetic traits as a result of …
