Appendix A. Composition of species richness (SR) and functional richness (FR) used in experimental assemblages.

TABLE A1. Composition of species richness (SR) and functional richness (FR) used in experimental assemblages. Functional groups are grasses (G1, species a and b + G2, Poa sandbergii), early-season rhizomatous forbs (F1, species a–c), late-season rhizomatous forbs (F2, species a–c) and mid-season tap-rooted forbs (F3, species a–c). The 16 species assemblage (treatment # 23) contains the additional grass (G2 , Poa sandbergii) and forbs from two additional functional groups, perennial spring ephemerals (F4a, Dodecatheon pulchellum and Fb, Lewisia rediviva) and late summer, tap rooted species (F5a, Aster falcatus and Fb, Artemesia frigida). These species were not grown in monoculture. Where specific species identity is not shown (i.e., “x” or “y” subscript) a species was drawn at random from the pool of three species from that particular functional group.
