Studies of female mate choice commonly use virgin females as test subjects, either to control
for the effects of mating or because virgin females are presumed to be more responsive to …

Behaviors associated with reproduction are major contributors to the evolutionary success of
organisms and are subject to many evolutionary forces, including natural and sexual …

Compared to those of their parents, are the traits of first-generation (F1) hybrids typically
intermediate, biased toward one parent, or mismatched for alternative parental phenotypes …

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

The target gene of rapamycin (TOR) is conserved from invertebrates to vertebrates, and
plays critical roles in cell growth, nutrient sensing, lifespan and reproduction. In this paper …

Divergence in phenotypic traits often contributes to premating isolation between lineages,
but could also promote isolation at postmating stages. Phenotypic differences could directly …

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

Complex sets of cues can be important in recognizing and responding to conspecific mating
competitors and avoiding potentially costly heterospecific competitive interactions. Within …

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 …

The relative importance of male and female mating preferences in causing sexual isolation
between species remains a major unresolved question in speciation. Despite previous work …
