Summary test statistics for a linear mixed model with ln(larval length) as response variable and replicate as a random effect. Adjusted R²: 0.712. N = 709. The parameter estimates are available in table A1 in Additional file 1. Square brackets indicate the nesting structure. Layout details: °d is the degree days-covariate, an asterisk between model term indicates interaction effect, and Df indicates degrees of freedom for the relevant model term.
