Relative importance values (RIVs) of weather variables for total species (A) richness and (B) Shannon diversity (H') for Shortgrass Steppe. RIVs are calculated as the sum of Akaike weights (wi) across all models in which a given variable appeared. See Appendix B for description of all a priori models and Supplement 8 for all results of AICC analyses. CV = coefficient of variation, sum = summer, spr = spring, win = winter, PPT = precipitation, TEMP = temperature, t_1 = season preceding growing season (spring and summer) when plants were sampled.
