Fig. 3.
High-competition males show reduced mating completion after multiple matings. Males were held alone (no competition), in a same-sex pair (low competition), or in a same-sex group of 8 (high competition) before being provided with 5 successive virgin females. Male latency to mating is plotted for each mating. P values are for the overall effect of competition. Data were pooled from two replicates. Confidence intervals are given at 95%. At the start of first mating, nno = 133, nlow = 137, nhigh = 131. By the end of fifth mating, nno = 121, nlow = 133, nhigh = 114.
