Appendix D. Dietary data for cannibals and victims in three mesocosm experiments on tiger salamander cannibalism. The data were first analyzed using a two-way MANOVA for the effects of cannibal presence and size of potential conspecific victims on diet.  Because there was no or weak evidence for cannibal-induced  niche shifts in any of the size classes of victims, we combined  the victim data from tanks with and without cannibals within the three experiments for comparison to the cannibal diets in part 2 below.

FIG. D1. Comparative diets of tiger salamander size combinations (paedomorphic adults and age 2+ and 1+ yr larvae) in mesocosm cannibalism experiments. Bars with lower case letters indicate groups of means that do not differ based on Tukey’s post hoc tests for significant ANOVA results (above).

FIG. D2. Comparative diets of tiger salamander size combinations (paedomorphic adults and two size classes of YOY larvae) in mesocosm cannibalism experiments. Bars with lower case letters indicate groups of means that do not differ based on Tukey’s post hoc tests for significant ANOVA results (above).

FIG. D3. Comparative diets of tiger salamanders (age 3+ yr, 1+ yr, and two sizes of YOY larvae) in mesocosm cannibalism experiments. Bars with lower case letters indicate groups of means that do not differ based on Tukey’s post hoc tests for significant ANOVA results (above).
