The split-plot design used to test whether intraspecific functional variation of dominant species affects community composition and structure over the first 4 yr of community assembly. Six whole plots were randomly assigned to cultivar (n = 3) and non-cultivar (n = 3) source of three dominant grasses within each of two adjacent agricultural fields (blocks). Three unique designed species pools (A–C) of subordinate prairie species were randomly assigned to 5 × 5 m subplots within each whole-plot. This figure also appears in Baer et al. (in review).
