  1. In the GLMs, standard length (SL) and either one of the morphological indices (MI1–3) were incorporated as explanatory variables. Coefficients (Coef.) indicate the regression estimate values. The z values in tests for frequency of attacks and proportion of amphipods are the statistics in Poisson and binomial models, respectively
