Size dependence of offspring production in isopods: a synthesis.

When we centred the model at the minimum female body mass (21.682 mg.), clutch size and offspring body mass appeared to be unrelated (t 1,97 =0.44, p=0.66), but centring at the maximum body mass (131.236 mg) revealed a negative relationship between clutch size and offspring body mass, though the effect was marginally significant (t 1,97 =-1.98, p=0.05).
