Results of a single-factor ANOVA showing the local environment for each age class of juvenile walleye pollock (A, group depth; B, bottom depth ; C, group distance above the seafloor; D, adult pollock density; E, euphausiid density; F, sea surface temperature; G, group temperature; and H, bottom temperature). The error bars represent 95% confidence intervals about the mean and are sometimes obscured by the symbol. Black circles represent means from 2009, and the gray circles represent means from 2010. Mix 12 results (e.g., groups with 1 and 2 year olds) are plotted between age 1 and age 2, and mix 23 results (e.g., groups with 2 and 3 year olds) are plotted between age 2 and age 3. Lines above the symbols indicate no statistically significant differences were detected between those age groups based on Tukey's multiple comparison tests.
