M. Hornung et B. Reynolds, THE EFFECTS OF NATURAL AND ANTHROPOGENIC ENVIRONMENTAL-CHANGES ON ECOSYSTEM PROCESSES AT THE CATCHMENT SCALE, Trends in ecology & evolution, 10(11), 1995, pp. 443-449
The catchment is the smallest natural unit of the landscape that combi
nes linked terrestrial and aquatic ecosystems. The fluxes of water and
elements through the catchment link the various components of the sys
tem; biotic and abiotic, terrestrial and aquatic, plants and soils, at
mosphere and vegetation, soils and waters. A large amount of empirical
evidence now demonstrates that the impacts of natural and anthropogen
ic changes on the various components of catchment ecosystems are tight
ly connected.
