Abstract |
Dominance of N2-fixing algae has frequently been observed in freshwater environments in late spring or summer when the ratio of available N and P is low. This dominance is apparently due largely to the unique ability of the algae to fix atmospheric N2 while the limitation of combined N restricts the growth of non-N2-fixing species. As the ratio of available N to P decreases, P limitation changes to N limitation for the nonfixers, but for N2-fixing species N-fixation takes over as the primary source of N. In the present study the authors investigated how P requirements, C-fixation and growth kinetics of N2-fixing blue-green algae are affected by various inorganic N species. |
