Abstract We used a field experiment to test the effects of population density on the growth rate and survival of Austrolebias bellottii , a Neotropical annual killifish. Effects differed between the sexes: males at high densities achieved a smaller final size and experienced higher mortality while no such effects were observed in females. This sex‐specific effect could be an indirect consequence of mate competition.
