Fig. 3: Relative yield and relative growth advantage of the submerged macrophytes.

From: Eutrophication drives regime shift via changes in stoichiometric homeostasis-based submerged macrophyte assemblages

Fig. 3

a Relative yield total, b relative yield of Potamogeton maackianus, c relative yield of Hydrilla verticillata, d relative growth advantage of H. verticillata over P. maackianus. Error bars indicate standard errors (n = 3). Data were not obtained for H. verticillata under OP on day 90, as the plants died. Values with different lowercase letters are significantly different among P levels on the same day (p < 0.05). OP, MP, EP indicated three P levels of oligotrophic P (P concentration under detection limit and no P addition), mesotrophic P (0.05 mg L−1), eutrophic P (0.10 mg L−1), respectively. NSI indicates neutral species interaction (RY or RYT = 1); NSA indicates that there was no significant advantage (RGA = 0).
