Phototrophic picoplankton were detected in 105-106 cells/ml concentrations in seven water bodies of differing chemistry and trophic level. Dominant picoplankters were, at all sites, coccoid cyanobacteria of 0.8-1.2 pm dimensions, exhibiting red or yellow autofluorescence. Apart from the effects of w

โฆ Synopsis
Sites and methods
The populations of bacteria were followed for a year in two small shallow lakes, one naturally eutrophic (Upton Broad), the other culturally eutrophic (Alderfen Broad). In Upton Broad there were peaks in population in summer and late autumn. In Alderfen Broad peaks occurred at the beginning of the year, in spring and in autumn. Annual respiration amounted to 4.89 KJ1 -1 and 4.40 KJ1-' at Upton and Alderfen Broads respectively, with annual production estimated at 0.39 KJI-' and 0.35 KJI -'.
