OR 1- Figure 1: Individual gas exchange rates measured in grass, legume and forb monocultures () and mixtures (). Data are distributed along the x-axis in the order in which they were taken, so that peaks or differences between measurements can be observed. The observed exchange rates show values within the same order of magnitude. Only for CH₄ gas emission we find two values that exceed the average (3.08 mg m^-2 h^-1) in one order of magnitude. The figure includes data from the three measuring periods: May and June, when eight plots (6 monocultures and 2 centroid mixtures) were sampled and July, when a broader set of plant communities were included (6 monocultures, 2 centroid mixtures and 6 dominated mixtures). After the first fertilizer application in June, the measured rates include data for fertilized (light symbols) and unfertilized (dark symbols) plots.
