Seasonal pattern of nutrient concentration, I_mix and phytoplankton biovolume measured in MUEG and UH (2011).

<p>The colored bands above the graphs indicate the limitation type identified by the bioassays: where No is no limitation; Co is simultaneous or independent co-limitation; P is serial or single P limitation; N is serial or single N limitation; Light is light or co-limitation between light and nutrients. <b>A–D)</b> TN, DIN, TP and SRP; the horizontal lines mark the DIN and SRP concentrations below which N or P limitation are possible according to Maberly et al. <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0096065#pone.0096065-Maberly1" target="_blank">[41]</a>. <b>E</b> and <b>F)</b> I_mix, the horizontal line marks the light intensity below which in situ light treatments were conducted in the bioassays. <b>G</b> and <b>H)</b> Phytoplankton biovolume estimated according to Utermöhl <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0096065#pone.0096065-Utermhl1" target="_blank">[33]</a>.
