Equilibrium phytoplankton stoichiometry as a function of nutrient supply stoichiometry in chemostats.

<p>(A) Klausmeier et al. <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0107737#pone.0107737-Klausmeier1" target="_blank">[15]</a> model predicted phytoplankton N: P under three dilution (growth) rates. The solid line represents Rhee's <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0107737#pone.0107737-Rhee1" target="_blank">[36]</a> experimental setup, with dilution (growth) rate α = 0.59 d⁻¹. The dashed and dotted lines represent higher dilution rates, α = 0.9 and α = 1.05 d⁻¹, respectively. (B) Dependencies of the molar ratios of N:P of <i>Rhinomonas reticulata</i> cells at a range of inflow N:P ratios under high light (open symbols) and low light (filled symbols). The dashed-line represent the 1∶1 line and error bars represent standard deviation <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0107737#pone.0107737-Leonardos1" target="_blank">[17]</a>. Since this example is a clear case but there are only very few data points, the solid line is fitted by eye to the data.
