Abstract
Enumeration and measurements of cell size in Baltic picoplanktic cyanobacteria were performed by video recording of autofluorescent images of unicells with a diameter of 5 cells ml−1 from the surface to 20 m depth, with an average value of 5.6 and 3.8 × 105 cells ml−1 in July and August, respectively. Thee size classes were distinguished on the basis of morphometric analysis, as well as four types of cell aggregates frequently occurring in the samples. Variations were detected between the 2 months in picocyanobacterial populations present in the mixed layer, mainly concerning decrease in cell number, and increase in dimensions in August. Ecological and taxonomic implications arising from the data are discussed.Keywords
