Electronic Supplementary Material 2 Results of community-based approach analysis. The changing incidence of traits during the course of succession revealed by comparing weighted trait values with the abundance of species over time in the different communities. Arrows indicate a significant (P<0.1) direction of the change in incidence (increasing and decreasing) and/or dynamics of the attribute with the age of the succession. ∩ and U indicate peak and valley-shape dynamics of the attribute during succession. (P) – primary succession, (S) – secondary succession
