<p>(<i>a</i>) The mean root/shoot ratio varied with heterospecific interactions from monocultures, aggregated to dispersed mixture plots. (<i>b</i>) The within-plot mean (left bars) and standard deviation (right bars) in plant height (in cm, calculated over all grids in each plot) versus heterospecific interactions. (<i>c</i>) The average height for each of the eight species varied from monocultures, aggregated mixtures to dispersed mixtures. Data bars for the root/shoot ratio in (<i>a</i>) and the mean height in (<i>b</i>) are mean+1 standard error. Bars with different letters above are significantly different at <i>P</i> = 0.05. The values for the standard deviation for height are shown in (<i>b</i>).</p
