Gender-dimorphic plants are often subject to sex-differential enemy attack, but whether and
how this contributes to trait evolution is unknown. To address this gap, we documented the …

We explore the effects of gender dimorphism on resistance (damage avoidance) and
tolerance (growth and fitness compensation) to a flower bud clipping weevil in a …

Evolutionary biologists have repeatedly argued that environmental factors have influenced
the evolution of dioecy (males and females) from hermaphroditism in plants. While many …

The optimal deployment of reproductive resources by hermaphrodites to male versus female
function (ie, their sex allocation) depends directly on opportunities for mating. If …

Hermaphroditic animals often exhibit mating mechanisms that seem more damaging than
those in species with separate sexes. Our analyses indicate that this difference is real. While …

We explored the idea that sex ratio represents a unique context for selection on attractive
traits by manipulating sex ratio and pollinator abundance in experimental populations of a …

Sex-specific interactions with antagonists may explain female maintenance in
gynodioecious populations if seeds produced by hermaphroditic plants are preferred over …

Summary 1 In gender dimorphic species, reproductive allocation (RA, the ratio of
reproductive to vegetative biomass) is predicted to be greater in female plants than in male …

In dioecious plants, males and females frequently show 'leaky'sex expression, with
individuals occasionally producing flowers of the opposite sex. This leaky sex expression …

Sex ratios are subject to strong frequency-dependent selection regulated by the mating
system and the relative male versus female investment. In androdioecious plant populations …
