Mating duration following the first and second matings in the Two Exposures experiment. R = held with a rival, 0 = without a rival prior to each mating (e.g. R0 = first exposure was with a rival, second exposure without a rival). (a) Mating duration at each mating. (b) The difference in mating duration between first and second matings standardized to the mean of the ‘no change’ treatments. Asterisk indicates a significant difference from the ‘no change’ regime, after applying sequential Bonferroni correction.
