Individual-level reproductive success of males during sperm competition and extra-territorial mating. Mean and standard errors are calculated from two competition enclosures using parentage analysis. There were no effects of paternal breeding treatment on the size of mixed (multiple paternity) (A) or pure (single paternity) (B) litters. Individual promiscuous (P) line males (circles) had more offspring within their own defended territories (within-territory), inside the territories of neighboring dominant males (extra-territory), and in undefended territories than monogamous (M) line males (squares) (C).
