Comparison of the allometric model (value of b regressed by model fitting) to the isometric model (b = 1).

As the allometric model we used the predictive regression equation ‘mI + II + III’. As size at the event of interest, we used average values at hatching SCL = 4.5 cm [33], recruitment SCL = 48 cm [9], and nesting SCL = 93 cm [28, 31] for the relationships of carapace width and body depth to carapace length. For the relationship of body depth to carapace width we calculated SCW values that would correspond to average carapace lengths at hatching, recruitment, and nesting, using ‘mI + II + III’. Error was calculated for loge transformed data as [100(value predicted by isometric model—value predicted by allometric model)/ value predicted by allometric model].
