Table 2. Parameters of ordinary least-squares regressions between body dimensions.
Parameters (with 95% confidence intervals, CI) of ordinary least-squares regressions with untransformed values of dependent (Y) and independent (X) variables, describing relationships between measurements of body size (mm) and weight (mg) for pueruli and first juveniles of Panulirus argus collected in Puerto Morelos and Bahía de la Ascensión between August 2012 and September 2013. Regressions were computed separately for pueruli and first-stage juveniles and the slopes statistically compared between developmental stages; when slopes did not differ significantly, intercepts were compared.
