Abstract:There is an increasing interest between abiotic and biotic environments of rivers, lakes, estuaries and seas. In the Wadden Sea, biological activity can have a considerable influence on changes in bed level and composition. For example, Macoma balthica redistributes and destabilises the bed by motion through the bottom. Diatoms stabilise the bed by forming a sticky substances which glues the sediment together. Mussel bed increase the roughness of the bed and by filtrating the water column, they increase the deposition of faeces between their shells. Apart from natural hazards to biology, like cold winters and storms, there is a huge scala of human interests, which can influence biology. There are industrial interests like gas and sand mining, and fishery, or recreational interests, like mud pounding (in Dutch: wadlopen), and water sports.
