Fig. 1 — The relative yield total (RYT) for a water treatments: ambient (dotted line, solid triangles) and decreased (solid line, solid circles); b nutrient treatments: ambient (black line, solid circles) and elevated (gray line, solid triangles). A mixed-effects model demonstrated that RYT responded negatively to water availability (n = 86, P = 0.030), but positively to elevated nutrient availability (n = 86, P = 0.027) and pot proportion of Pseudoroegneria spicata (n = 86, P < 0.001)
