Appendix D. Three tables summarizing the ANOVAs for the net effect from 2003–2007, and for the complementarity effect and selection effect in 2003, 2005–2007, using a statistical model in which species richness was fitted prior to functional group composition (described as model 1 in the Methods section).
Tables D1–D3: Summary of the ANOVA for NE (D1) from 2003–2007, and CE (D2) and SE (D3) in 2003, 2005–2007 (model 1 in "Methods"), using typeI sums of squares. Indented terms show the linear contrast for FG richness and its deviation from linearity (FG composition residuals). The sum of these two terms corresponds to FG composition. Year was fitted as a 5level factor for NE and as a 4level factor for CE and SE. The column % contains the proportions of explained betweenplotvariation.
