Male genitalia show patterns of divergent evolution, and sexual selection is recognised as
being responsible for this taxonomically widespread phenomenon. Much of the empirical …

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 …

Adult dietary restriction (DR) extends lifespan, but the mechanisms that underlie this effect
are not well understood. Many DR studies have demonstrated that lifespan extension tends …

Increased protein intake by adults typically enhances reproduction and shortens life, but
much less is known about the effects of protein intake prior to reproductive maturity. In …

Newly discovered non‐genetic mechanisms break the link between genes and inheritance,
thereby also raising the possibility that previous mating partners could influence traits in …

Competitive displacements or reductions of resident populations of insects, often effected by
a related species, may be caused by a variety of mechanisms. Satyrization is a form of …

Within-population variation in ageing remains poorly understood. In males, condition-
dependent investment in secondary sexual traits may incur costs that limit ability to invest in …

External male reproductive structures have received considerable attention as a cause of
reproductive isolation (RI), because the morphology of these structures often evolves rapidly …

Male genital morphology is remarkably diverse across internally fertilizing animals, a
phenomenon largely attributed to sexual selection. Ecological differences across …

We investigated the oviposition behavior of Ae. aegypti and Ae. albopictus. In particular we
examined whether small‐scale site characteristics and the presence of conspecifics or …
