Table 1. Effects of developmental stage and location on body dimensions.

Results of separate general lineal models testing for effects of developmental stage (two levels, pueruli and first juveniles) and location (two levels, Puerto Morelos and Bahía de la Ascensión) on five body dimensions of individuals collected between August 2012 and September 2013: carapace length (CL), weight (W), total length (TL), carapace height (CH) and carapace width (CW).
