Landscape Ecology of Aquatic Ecosystems

Landscape ecology has only a short history as a recognized discipline, but it has transformed our thinking about the interplay between pattern and process. We now understand that many smaller-scale phenomena are driven by spatial processes, such as the proximity of different habitats to one another, the ability of organisms to move through landscapes, and the dynamics of natural disturbance...
