Linear regression of dry mass (DW), carbon (C), nitrogen (N), and energy content of eggs and larvae from Mar Chiquita (MC) and San Antonio (SA) populations. Y-intercept, slope, coefficient of determination (R ²) and significance level of correlations (P) are shown
P homogeneity of the slopes of the equations of both populations for each variable, ANCOVA P′-value of ANCOVA analysis for the same variables
*Significant values of P and P′
