From this enjoyable and successful occasion, augmented by additional written contributions, the present vo

Succession of phytoplankton in a deep stratifying lake: Mondsee, Austriaing the year 1982. Secchi-disk transparency varied from 10 m in winter to 2 m in September. Prior to the onset of stratification phosphate-phosphorus concentration was 4 .g 1. decreasing to undetectable values thereafter. Nitrate-nitrogen dropped from 590 .g l. to about 100 .g 1. during the same tim

Seasonal variation in size spectra of phytoplankton assemblages in Loch Leven, Scotlandpecies in the shallow eutrophic Loch Leven (S.E. Scotland). Two-weekly samples over the period 1979–1982 have been analysed to determine whether variation in size spectra show seasonal trends. Size frequency distributions are displayed using — for the first time in studies of phytoplankton assemblag

Experimental manipulations of the phytoplankton periodicity in large limnetic enclosures in Blelham enclosures at Blelham Tarn, English Lake District. Three categories of manipulations are considered..The effects of variation in the scale and frequency of phosphorus loading (range: 0.3 to 2.5 g P m. a.) upon the mean phytoplankton biomass, its seasonal distribution and specific dominance are show
