Fig. 2.
Height response under ambient and decreased water (black and gray, respectfully) for a Bromus tectorum in ambient (long dashed line, solid circles) and elevated (dotted line, solid triangles) nutrients and b Pseudoroegneria spicata in ambient (solid line, open circle) and elevated (short dash line, open triangles) temperature. Mixed-effects models demonstrated: a B. tectorum height was negatively affected by P. spicata pot proportion (n = 106, P < 0.001) and decreased water (n = 106, P < 0.001), while it responded positively to increased nutrients (n = 64, P < 0.001); b P. spicata height was negatively affected by P. spicata pot proportion (n = 106, P < 0.001), increased temperature (n = 106, P < 0.001), and decreased water (n = 106, P < 0.001)
