Much of the primary production within the channels of streams and rivers, particularly those with fast flowing water, is typically restricted to benthic habitats involving algae and cyanobacteria. PRIMARY PRODUCTIVITY IN A SOUTHERN GREAT PLAINS STREAM1 William R. Duffer2 and Troy C. Dowis Aquatic Biology Laboratory, Oklahoma State University, Stillwater 74075 ABSTRACT Physico-chemical conditions and community metabolism in a relatively undisturbed stream in Oklahoma were studied from June 1963 to August 1964. Liao, C. F.-H. and D. R. S. Lean. To explore how the variation in primary production within and among individual stream reaches can give rise to emergent river network productivity regimes, we scaled annual stream productivity regimes using simulated river networks.

In streams, primary producers generally are associated with benthic substrates, and include algae, cyanobacteria, bryophytes, and vascular macrophytes, although algae are usually the major producers. 1979. Report to U.S. These studies showed the importance of allochthonous organic matter inputs supporting consumer organisms and gave rise to the generalization that stream ecosystems were heterotrophic (i.e., that respiration exceeded photosynthesis annually, Hynes, 1963; Cummins, 1974). 1977.

Although rates of net primary production are similar across ecosystems (Cebrian 1999), herbivorous zooplankton in lakes remove a three to four times greater proportion of primary productivity than grazers in terrestrial systems (Cyr & Pace 1993; Hairston & Hairston 1993; Cebrian 1999), and aquatic consumers can be anywhere from six to sixty times more abundant on an areal basis within … 1964.
