Comparison of results of linear regression and randomization analyses

Sizes of diaspores presented to ants.

<p>Mean (± SE) a) seed mass, b) elaiosome mass, and c) ratio of elaiosome to seed mass for seeds collected by ants in removal trials. Different letters indicate statistically significant differences (Tukey-adjusted p≤0.05).</p

Oleic acid content of the focal myrmecochorous species.

<p>Mean (± SE) concentration of free oleic acid in elaiosomes. Different letters indicate statistically significant differences (Tukey-adjusted p≤0.05).</p

Seed removal by <i>Aphaenogaster rudis</i> workers.

<p>Numbers of diaspores of <i>Asarum canadense, Sanguinaria canadensis, Trillium erectum,</i> and <i>Trillium grandiflorum</i> removed by workers within one minute, out of a total of 48 presented to colonies. Time to removal was measured from the time workers first discovered a diaspore. Different letters indicate statistically significant differences in removal, as assessed by full survival analysis models (see text).</p

Effects of diet treatment on colony performance.

<p>Mean (± SE) a) brood mass and b) numbers of eggs, c) larvae, and d) dead workers 10 weeks after treatment. Different letters indicate statistically significant differences (Tukey-adjusted p≤0.05).</p
