How barriers to gene flow arise and are maintained are key questions in evolutionary
biology. Speciation research has mainly focused on barriers that occur either before mating …

Insect male genitalia are among the fastest evolving structures of animals. Studying these
changes among closely related species represents a powerful approach to dissect …

Research over the past three decades has shown that ecology-based extrinsic reproductive
barriers can rapidly arise to generate incipient species—but such barriers can also rapidly …

The aim of this study rests on three premises:(i) humans are altering ecosystems
worldwide,(ii) environmental variation often influences the strength and nature of sexual …

Genital morphology reveals rapid diversification among species, and species-specific
divergence in genital morphology may result in reproductive isolation and promote …

Natural selection against maladaptive interspecific reproductive interactions may cause
greater divergence in mating traits between sympatric populations than between allopatric …

Secondary contact between incipient species and selection against maladaptive
hybridization can drive reinforcement between populations in contact and result in …

In reproductive interference (RI), the fitness of individuals or populations is decreased
through reproductive interactions with other species. This process results in positive …

The rapid divergence of genital morphology is well studied in the context of sexual selection
and speciation; however, little is known about the developmental mechanisms underlying …

To understand geographic body size variation in an insect species, various factors including
habitat temperature, correlation between life history traits, and food availability must be …
