After providing an introduction to the physical and chemical circumstances of running water, there is an analysis of the biology and ecology of these systems, covering the following topics: the ecological role of autotrophic and heterotrophic energy producers; the trophic ecology of consumer organisms in lotic food webs; the community ecology of flowing waters, including herbivory, predation and competition, and their integration with abiotic factors in determining comm...
