Results of five separate generalized linear mixed models analyzing variation in estimated total phenotypic selection (STS) on five traits of Gilia tricolor experimental plants across three habitat zones and two years.

Separate series of models were conducted for each of five plant traits analyzing interactions between trait, habitat zone, and year. Significance of fixed effects was assessed by likelihood ratio tests (LR) using single-term deletions; plot was a random effect in each model. Fitness was relativized and traits were standardized within habitat zone and year. Effects significant at the P§denotes where the exterior habitat zone was excluded from analyses because of limited sample size in 2008.*denotes tests that showed significant variation in direct phenotypic selection (βDS) when biomass was included as a covariate.
