Below is my attempt to represent the main river ecosystem concepts schematically. Read through the four parts of the brief history to get fuller descriptions of the concepts. From left: the Fish Zone ‘Concept’ (strictly, a typology or classification) defines zones based on resident species; the River Continuum Concept emphasizes downstream processing of imported organic matter and predicts that fish species richness increases with stream size; the Flood Pulse Concept maintains that the seasonal ‘flood pulse’ drives floodplain river food webs, and that the floodplain is a nursery and a food source for fish in the channel; the Riverine Productivity Model emphasizes the productivity of local river-edge communities; and the Riverine Ecosystem Synthesis combines the RCC, FPC and RPM and refers to progressions of ‘habitat’ patches formed by local geomorphology and climate.
Aims of this site
This site and blog is mostly about the science of rivers, although it will include cultural aspects of rivers when they catch my eye and take my fancy. It will highlight ideas, concepts and research of interest to students, researchers and managers.
