Outcome of mating and remating trials in terms of plugging success, including (a) the number of sperm plugs deposited in females’ paired genitalia by first-mating males; (b) the relationship between male size-corrected mass and plugging success (two plugs vs. one or no plugs) for first-mating males; (c) the number of plugs placed by second-mating males (and how many plugs were already present); and (d) the relationship between relative male size-corrected mass and plugging success (one or two plugs vs. no plugs) for second-mating males (d). Points (b,d) represent raw data, lines are predicted fits and grey areas are approximate 95% CIs from GLMs where male size or size difference is set at its mean for prediction
