Linear mixed effect models for the response variables of total length (mm) and estimated age (year).

<p>Columns present the estimates of differences (positive or negative) of group response variables with the intercept (piscivorous ecotype), standard error and <i>p</i>-values of the factor. <i>p</i>-values in bold are significantly different. The two-terms coefficients (separated by hyphens) represent the nested factors.
