Appendix A. Primary patterns of variation among sites, years, and site × year combinations, in rates of visitation by five classes of visitor to Ipomopsis aggregata.

† Year, Site, and Year × Site interaction are independent variables. Dependent variables are five visitor groups: hummingbirds, long-tongued bumble bees, Lepidoptera, nectar-robbing bumble bees, and pollen-eating small insects.
