Abstract |
The heterogeneity of habitat structure as well as water quality are main factors for the maintenance of a diverse fish fauna in rivers. One of the most promising approaches to improving management of riverine ecosystems is the maintenance and restoration of well-functioning land-water ecotones. The buffering strip between land and water determines habitat structures, acces to light, and temperature. It reduces the transfer of nutrients and pollutants and stabilizes the organic matter supply to the aquatic environment. These factors to a great extent influence the structure and function of fish communities. The hierarchy of ecotone effects changes in a predictable pattern along the river course. |
