The distribution and abundance of chroococcoid cyanobacteria

Abstract: The abundance of phycoerythrin-containing chroococcoid cyano-bacteria in the surface waters between Australia and Antarctica were determined by counts of yellow autofluorescing cells on four transects of the Southern Ocean in the 1985/86 austral summer and by analysis of the pigment zeaxan...

Description
Summary:Abstract: The abundance of phycoerythrin-containing chroococcoid cyano-bacteria in the surface waters between Australia and Antarctica were determined by counts of yellow autofluorescing cells on four transects of the Southern Ocean in the 1985/86 austral summer and by analysis of the pigment zeaxanthin. Despite widely differing daylengths on these transects the principal determinant of cyano-bacterial abundance appears to be temperature, with cell number being exponential-ly related to water temperature. Ultrastructural differences found in the cell wall of Southern Ocean cyanobacteria may indicate the presence of different strains. 1.
