Dynamics of water phosphorus in summer.

<p>Dynamics of water phosphorus (in μg.l⁻¹.g⁻¹ of plant initial dry mass) and results of a linear model regression analyses under eutrophic and hypertrophic conditions, for all the possible combinations of water and subpopulation, during the summer experiment. In the legend, AA, AV, VA, VV include the information on the treatment, the first letter refers to the type of water and the second one to the subpopulation (e.g. AV means <i>Alsatian</i> water and <i>Vosgian</i> subpopulation).
