Effects of social dominance and breeding treatment on survivorship. Data are from 10 competition enclosures over 35 weeks. Regardless of treatment, socially dominant (half-filled circles) individuals had greater survivorship than subordinates (triangles) for both male (A) and female (B) founders. Promiscuous line males that were socially dominant (circles) had significantly lower survivorship than monogamous line males that were socially dominant (squares) (C).
