Abstract
Seasonal zooplankton dynamics in two coastal lagoons differing in degree of their eutrophication are compared. The two water bodies show no clear difference with respect to calanoid copepods. Rotifers in the more eutrophic lagoon show a pronounced peak of abundance in early summer, not observed in the less eutrophic lagoon. It is concluded that grazing of bacteriodetritivorous rotifer species is an important regulator of primary production.
Highlights
Seasonal zooplankton dynamics in two coastal lagoons differ· ing in degree of their eutrophication are compared
An attempt is made to correlate differences in the degree of eutrophication with seasonal variation of a biotic compo nent, i.e., metazooplankton biovolume, in two lagoons differing in the extent of their eutrophication: the highly eutropic chain of boddens south of the Darss-Zingst penin sula (Darss-Zingst Boddens) and the Polish part of the Vistula Lagoon (Fig. 1)
The Vistula Lagoon is only slightly influenced by freshwater run-off from rivers and is less eutrophic (Table 1 ), The aim of this work is to find out whether the difference in extent of eutrophication can lead to major differences in the zooplankton dynamics
Summary
Seasonal zooplankton dynamics in two coastal lagoons differ· ing in degree of their eutrophication are compared. Semi-enclosed shallow brackish water lagoons (boddens) are ecosystems typical of the coastal area of the Southern Baltic. These nontidal horohaline waters exhibit stronf variations in the seasonal dynamics of biotic components due to their shallow· ness and hydrographic variability. An attempt is made to correlate differences in the degree of eutrophication with seasonal variation of a biotic compo nent, i.e., metazooplankton biovolume, in two lagoons differing in the extent of their eutrophication: the highly eutropic chain of boddens south of the Darss-Zingst penin sula (Darss-Zingst Boddens) and the Polish part of the Vistula Lagoon (Fig. 1). The Vistula Lagoon is only slightly influenced by freshwater run-off from rivers and is less eutrophic (Table 1 ), The aim of this work is to find out whether the difference in extent of eutrophication can lead to major differences in the zooplankton dynamics
