Regressions generated from mean data calculated from six individuals belonging to each of the five juvenile life stages, at each temperature. N = 30 juvenile individuals per temperature. N = 90 juvenile individuals in total. Equations are in the form y = aM b (±95% CI), where y is the variable of interest, a is the coefficient (elevation), b is the exponent (slope), and M is body mass in grams.
NS
Indicates no significant difference in slope between temperatures (ANCOVA, P>0.05);
*indicates a significant difference in elevation between 15 and 25°C (P<0.05);
†
indicates a significant difference in elevation between 15 and 35°C (P<0.05);
‡
indicates a significant difference in elevation between 25 and 35°C (P<0.05).
