Statistical results from univariate ANOVAs, following a MANOVA, to examine the relative abundance and relative biomass of seven species groups in the diet of Forster’s tern (<i>Sterna forsteri</i>) at repeatedly sampled colonies in south San Francisco Bay during 2005–2015.

The model for each species was first run with a year × colony interaction. We removed any non-significant interactions and reran the model to test the effect of year and colony. Significant effects are bold and italicized.
