Harpacticoid copepod community structure in two North Sea estuaries in relation to pollution OMA
Van Damme, D.; Heip, C.H.R.; Herman, R.; Vaeremans, M..
The harpacticoid copepod assemblages of two estuaries in the Netherlands, the Westerschelde and the Eems-Dollard, are compared. Both estuaries have similar physical characteristics but the Westerschelde is much more polluted than the Eems-Dollard. Harpacticoid copepod assemblages in both estuaries are similar in terms of species composition. However, there is a striking difference in quantitative characteristics : the highest annual averages of density, biomass and diversity in the Westerschelde are below the lowest annual averages in the Eems-Dollard estuary. Because both estuaries are extensively monitored, data concerning many possible causes of this difference could be compared. It is argued that it is the high load of heavy metals in the Westerschelde...

Influence of pollution on the harpacticoid copepods of two North Sea estuaries OMA
Van Damme, D.; Heip, C.H.R.; Willems, K.A..
Seasonal monitoring of the meiobenthos in the Dutch estuaries revealed an anomaly in density and diversity of harpacticoid copepods in the Westerschelde. Another Dutch estuary, the Eems Dollard, has comparable hydrodynamical, physical and sedimentological, characteristics and a similar fauna, but even in the severely organically polluted oligohaline mudflats of this estuary, annual average density and diversity of endo-epibenthic harpacticoid communities are higher than at similar less enriched meso- to polyhaline biotopes of the Westerschelde. Besides the concentrations of inorganic pollutants, such as phosphates and nitrates, the concentration of pesticides, cyanide, detergents, phenols, oils, polychlorobenzenes, polycyclic aromatic hydrocarbons and...
