Eutrophication as a possible cause of decline in the seagrass Zostera noltii of the Dutch Wadden Sea

The present thesis describes the results of research on the distribution and possible causes for the decrease of the seagrass Z. noltii in the Wadden Sea, carried out from 1986 to 1990. Chapter 2 examines the relation between the distribution of Zostera dominated ecosystems in the international Wadden Sea and several possibly limiting environmental factors, i.e. period of emersion, sediment type, sediment stability, mean salinity and geographical region. Chapter 3 describes the former and present distribution of Z.noltii dominated ecosystems in the Dutch Wadden Sea in relation with their envir... Mehr ...
