  • Ecological constraints on planktonic nitrogen fixation in saline estuaries. I. Nutrient and trophic controls 

    Marino, Roxanne; Chan, Francis; Howarth, Robert W.; Pace, Michael L.; Likens, Gene E. (Inter-Research, 2006-03-15)
    Heterocystous, planktonic cyanobacteria capable of fixing atmospheric N2 into available nitrogen (N) are common and critically important to nutrient cycling in many lakes, yet they are rarely observed in estuaries at ...
