Variability of nitrogen fixation in some isolates of Nostoc linckia.
Four clonal isolates of Nostoc linckia isolated from different localities were compared with respect to growth, nitrogen content (cellular and extracellular), and pigment composition. A considerable range of variation was observed among these isolates. This indicates the existence of genetically distinct clonal populations of the alga in natural habitats.
