Trait means for each functional group.

<p>Trait means ± standard error for the functional groups from plants grown in a greenhouse on mesotrophic acid soil. FG1 is dominated by perennial forbs and grasses, FG2 is dominated by caespitose grasses, while FG3 has annual grasses, forbs and legumes.</p>*<p>information taken from the Ecoflora database (<a href="http://www.ecoflora.co.uk/" target="_blank">http://www.ecoflora.co.uk/</a>).</p

Effect of precipitation change and functional identity on photosynthetic rate at different time points.
