Relationships between the major environmental variables and functional redundancy. Relationships for the vascular plant community a and bryophyte community b. Black lines represent the whole plant community (black), while the coloured lines represent the plant species in the two co-response clusters (blue = cluster I, red = cluster II). MAT = mean annual temperature (°C), TS = seasonality in temperature (°C), MAP = mean annual precipitation (mm), SO _x  = total sulphur deposition (mg m⁻² yr⁻¹), NH _x  = total reduced nitrogen deposition (mg m⁻² yr⁻¹). Linear regression models and two-tailed P-values are shown in Table 1
