Multiple regression models testing for geographic clines in flowering time with and without control for neutral processes and climatic variation. All models were conducted on inbred line means for Arabidopsis thaliana plants grown in a common garden experiment in Toronto. Principal components (PC) describe mean monthly climate at home from October through to April, for the variable indicated in the column header. Gray shading indicates that the term was omitted from the model. Significant effects at α= 0.05 are bolded.
