Model terms are food availability, rearing temperature, water depth, and sex. Generalized least-squares method was used to address heteroscedasticity between food treatment levels (Zuur et al. 2009). Factors were selected using backward elimination until all P-values ≤ 0.05 or only main effects remained (Quinn and Keough 2002).
