Table 4 Deviance explained by Generalised Dissimilarity models (GDM) for each functional trait of Juniperus thurifera in plots at three forest stages

From: Functional distance is driven more strongly by environmental factors than by genetic relatedness in Juniperus thurifera L. expanding forest stands

  1. In bold, values for models with significant (* p < 0.05) or marginally significant ((*) 0.05 < p < 0.1) p values. Functional traits shown are carbon isotope signature (δ13C), the ratio between leaf carbon and nitrogen concentrations (C:N), leaf carbon concentration (Ccon), leaf nitrogen concentration (Ncon), leaf dry matter content (LDMC), wood density (W.DEN) and a combination of the individual traits studied (COMB). Plots correspond to M1, M2, M3, M4 and M5 (Mature forest stage); to T1, T2, T3, T4, T5 and T6 (Transition forest stage); and to E1, E2, E3, E4, E5 and E6 (Expanding forest stage)
