Stress and disturbance in the phytoplankton community of a shallow, hypertrophic lake,rbœk Fjord, Denmark..The present data from Hjarbæk Fjord demonstrate the difficulties in distinguishing stress from disturbance in a phytoplankton community, and show that great changes in the phytoplankton community can take place within few days..A collapse of blue-green algae in late June 1986 ca

Diversity and succession of the phytoplankton in a small lake over a two-year period, physical and chemical properties of water, solar radiation energy and zooplankton. In the present paper, the fluctuations in phytoplankton diversity were studied in relation to environmental factors. The special aim for the study was to detect a relation between environmental disturbances and phyto

Hypertrophic phytoplankton and the Intermediate Disturbance Hypothesis,hypertrophic lagoon, paying special attention to the link between species-diversity and environmental disturbances. Phytoplankton diversity yielded different indices depending on the basic unit of calculations (cells, particles, phytoplankton units, biomass). Although their ranges were approximately

Disturbance-diversity relationships in two lakes of similar nutrient chemistry but contrasting distankton was primarily N-limited but diatoms were Si-limited. Plu.see had a very constant mixing depth during summer, while week-to-week changes of several meters were quite common in the more exposed Behler See. In Plu.see, phytoplankton biomass during summer came closer to the carrying capacity as d

Importance of intermediate disturbances for the species composition and diversity of phytoplankton ient limitation: Schlachtensee regularly stratifies very stably. In contrast, size and wind-exposure predispose Lake Tegel to deeper mixing; additionally, stratification is artificially destabilized by aeration. As the duration of aeration was varied, the study period includes interannual changes in

Some notes about the Intermediate Disturbance Hypothesis and its effects on the phytoplankton of th Seven sets of samples were taken from two channels formed below the confluence of Meta and Orinoco rivers between September 1990 and August 1991. The Orinoco river channel (ORISMA-1) had many more species than the Meta river channel (ORISMA2). Chlorophyceae dominated both, except during the rising
