Post-eruption recovery and secondary production of grazing insects in two streams near Mt. St. Helens

Creator:: Meyerhoff, Richard Dietrich
Abstract:: The eruption of Mt. St. Helens provided the opportunity to study secondary production of grazing insects in the context of disturbance. Two stream sites were chosen that significantly differed in how their watersheds were impacted by the eruption. Clearwater Creek was catastrophically disturbed (physical alteration of habitat, loss of riparian...

Energy transfer in an autotrophic-based ecosystem : with special reference to effects of fertilizer nitrogen additions

Creator:: Speir, Jon A. and U.S. International Biological Program. Coniferous Forest Biome
Abstract:: Three aspects of lotic ecology have been analyzed utilizing data collected from totally autotrophic-based streams maintained by the Weyerhaeuser Company: energy transfer, effects of nitrogen addition, and simulation modeling. All three streams had very similar periphyton, grazer, collector, invertebrate predator, and vertebrate predator (fish) communities during the study period (1972-1974)....
