Nested ANOVAs evaluating the random effects of Pollen Donor and Pollination Type (cross or self) nested within Pollen Donor on temperature-adjusted pollen performance traits in exilis (Stark Creek population), as well as in unguiculata, parviflora, and xantiana populations. We used the restricted maximum likelihood (REML) method to estimate variance components for each taxon. Effects associated with variance components whose 95% confidence intervals (CI) do not include zero are statistically significant and are indicated in bold italics.
