River/land ecotones: scales and patterns

  title={River/land ecotones: scales and patterns},
  author={Gernot Bretschko},
On a continental scale a river system itself is an ecotone, mediating between the terrestrial system and the sea. On the landscape scale, ecotones appear between terrestrial and river systems. At decreasing scales, the number and diversity of ecotones increases. Ecotone processes are discussed in relation to the entire ‘river’ ecosystem, on scales ranging from the activity range of fish fry up to that of adult fish.
