Cover of Impatiens glandulifera in summer 2016 in dependence of light and volumetric soil water content. A Cover of I. glandulifera is represented by point size and color as given in the legend. Grouping the plots into the micro-habitats moist–bright, wet–bright, moist–dark and wet–dark is based on the medians of light and soil water content. B Fitted function of the same data shown in 3d-space. f(cover) = light + light2 + light3 + water content + water content3. Linear model, R2 = 0.208, F(5,108) = 6.928, p < 0.001, n = 114.
