    Description: A working group of the Delta Institute at Yerseke, The Netherlands, studies the ecosystem of saline lake Grevelingen, a former estuary. The theme of the group is the cycling of organic matter in the two phases of the Grevelingen. The pool of particulate organic matter in the Grevelingen estuary (385 g C m-2 yr-1) was fed from various sources. The amount of organic carbon from the North Sea, entering the estuary as detritus equalled the in situ primary production. After the closure of the estuary the import of organic matter from the North Sea was completely cut off. Overall yearly production of the phytoplankton was not notably influenced by the closure, notwithstanding the large changes in environmental conditions. The significance of the phytobenthos production increased considerably. The total amount of organic matter available for consumers, decreased by roughly 40% to a level of 235 g C m-2 yr- 1. In the estuary net production of macrozoobenthos was estimated at 28 g C m- 2 yr-1. This production was almost divided by a factor two after the closure, just as the amount of food available. Changes in the feeding habits of birds may reflect the often less striking changes in the lower parts of the foodchains. Herbivore bird consumption has increased more than 20 fold after the closure. Consumption of zoobenthos showed a threefold decrease whereas the predation by fish-feeding birds increased about a 30 fold after the closure. The change from an estuarine into a stagnant saline ecosystem, bordering the North Sea, resulted in a sharp decrease in the amount of organic matter available as food, and a shift in the relative significance of predominant species.

    Notes: Abstract Traditional approaches for biomass assessment of estuarine macrophytes over vast areas are time consuming. A methodology for quick and accurate biomass estimation of macrophytes, growing at intertidal mudflats, has been developed and verified. Using a calculated relation between biomass and colour densities on the aerial photographs, biomass of macrophytes over a large area (ca 900 ha) could be assessed with an accuracy of about 10%. Biomass estimates could be partitioned over seagrasses, various green algae and brown algae.

    Notes: Abstract The 1930's wasting disease among the North Atlantic population of eelgrass,Zostera marina, is still an ecological and historical enigma, despite several attractive theories. Van der Werff investigated the die-back of eelgrass in the thirties in the Dutch Wadden Sea, and he considered the micro-organismLabyrinthula as the possible cause of the disease. In 1980, Grevelingen lagoon, harbouring an extensive population ofZostera marina, experienced a major decline of the area covered by the submerged macrophyte. Speculations about the cause of this dramatic decline induced us to think that the wasting disease had struck again. Van der Werff investigated the Grevelingen population and found bothLabyrinthula and a Chaetophoracean endophytic alga to be presumably responsible for the decline. During the quest for the ultimate cause of the wasting disease the question remains whether both micro-organisms are the cause of the disease or simply an effect of decomposition processes triggered by other factors.

    Notes: Abstract The wax and wane of the eelgrass (Zostera marina L.) population in Grevelingen lagoon (East Atlantic; The Netherlands) has been documented for over 25 years, together with quantitative and semi-quantitative data on environmental variables. The population expanded after the closure of the Grevelingen estuary in 1971, but declined from 4600 ha surface area in 1978 to less than 100 ha in 1993. There is little causal evidence which factors are responsible for the observed dynamics of the population. The incomplete picture emerging from the data is that of an extremely impoverished eelgrass population, living under constant oligo-mesotrophic marine conditions. Both the sexual and the vegetative modes of reproduction are severely stressed by environmental variables, most likely a combination of low temperatures, high salinity, low dissolved silicate and low ammonium concentrations. Survival of the population asks for the restoration of moderate estuarine conditions.
