Summary of mixed-effects models testing for effects of legume species identity and plant diversity on expression of traits related to light acquisition and performance in terms of shoot biomass.

Models were fitted by stepwise inclusion of fixed effects. The first columns show results of likelihood-ratio tests that were applied to assess model improvement (Chi2) and the statistical significance of the explanatory terms (Species = species identity, Diversity = monoculture vs. mixture), where* P ≤ 0.05,** P *** P Arrows indicate increases (↑) or decreases (↓) in trait values in mixture compared to monocultures. Tukey`s test was applied for multiple pair-wise comparisons of sample means per species. Abbreviations are Lp = Lathyrus pratensis, Lc = Lotus corniculatus, Mv = Medicago x varia, Ov = Onobrychis viciifolia, Th = Trifolium hybridum, Tp = Trifolium pratense, Vc = Vicia cracca.Summary of mixed-effects models testing for effects of legume species identity and plant diversity on expression of traits related to light acquisition and performance in terms of shoot biomass.
