Appendix F
Principal components analysis (PCA) of the nine environmental variables used to describe environmental conditions of each source population. These variables included spring precipitation, temperature (min, mean, and max), dew point (mean), vapor pressure deficit (min and max), elevation, and plant density as described in Mackin et al. (2021). FF = French Flat, HD = Hazel Dell, HR = Horse Rock, JF = Jefferson, LT = Lower Table Rocks, SL = Sublimity, UW = Upper Weir, WS = Whetstone.
