Eggs lost to predation	Wilcoxon signed rank	5.37  ±  0.26	6.13  ±  0.28	<0.01
Mating success of randomly chosen sons	Sign	22 of 30*	8 of 30*	<0.05
Mating success of mean-sized sons	Sign	23 of 30*	7 of 30*	<0.01
Fecundity of randomly chosen daughters	Paired t	392.01  ±  5.44	370.21  ±  7.08	<0.05

Values are means ± SEM. 

*The unit value represents the mean value for offspring from a particular mating.
