Male mating success in relation to age. Proportion of males accepted as mates for each age class when exposed to females in one-male choice experiment (A) or together with males of other classes (B). Overall comparisons reveal significant differences in the proportion of males accepted as mates among age classes (P = 0.043 and P < 0.001). In both series of experiments females tended to mate more frequently with older males. Error bars depict the 95% confidence limits for the proportions.
