Males can evolve lower resistance to sexually transmitted infections to infect their mates and thereby increase their own fitness

Johns, Sophie; Henshaw, Jonathan; Jennions, MIchael D.; Head, Megan

Description

Sexually transmitted infections (STIs) often lower their host's future reproductive success by inducing sterility. Females can minimise the reproductive cost of infection by plastically increasing their current reproductive effort (i.e. terminal investment) before they become sterile. In polyandrous systems, long-term female survival or fecundity is often irrelevant to male fitness. Mating with an infected, terminally investing female potentially yields greater fitness gains for males than...[Show more]
