Females know best: dispersal polymorphism maintained by sex-specific foraging

Polymorphisms are maintained over time by trade-offs that alternatively favor morphs over space or time. In a polyphenic population of amphibians (Arizona tiger salamander; Ambystoma mavortium nebulosum ), two morphs—paedomorphs and metamorphs—exhibit a trade-off in dispersal capacity. Larvae select...
