Successional changes associated with benthic assemblages in experimental streams

Creator:: Busch, David E.
Abstract:: Experimental streams constructed by the Weyerhaeuser Company, Tacoma, Washington, at Kalama Springs, Washington, were used to observe successional changes in the benthos. Community changes were observed relative to experimental manipulations of light intensity and nitrate concentration in two experiments. The development of benthic assemblages was followed for 150 days after...

Production dynamics of sediment-associated algae in two Oregon estuaries

Creator:: Davis, Michael W.
Abstract:: Sediment-associated gross primary production, oxygen uptake, microalgal biomass expressed as chlorophyll a concentration, macroalgal biomass and total organic matter concentration expressed as ash-free dry weight were measured monthly at medium sand, fine sand and coarse silt sites between 0.5 m and 2.0 m above MLLW during an entire year at...

Effects of current velocity, irradiance, and herbivory on algal assemblages in laboratory streams

Creator:: Steinman, Alan D.
Abstract:: Effects of current velocity, irradiance, and grazing on the biomass, taxonomic structure, physiognomy, and chemical composition of lotic algal assemblages were investigated. Four experiments, lasting 32 to 75 days, were conducted in laboratory streams to determine how these factors affect algal assemblages singly, and in concert with each other. Regardless...

The distribution of intertidal diatoms associated with the sediments of Yaquina Estuary, Oregon

Creator:: Amspoker, Michael C.
Abstract:: Sediment samples were collected from eight sampling sites along the Yaquina Estuary, Oregon from Yaquina Bay to Elk City near the head of the estuary. Samples were collected in November 1973, February 1974, May 1974 and August 1974 from two or three intertidal levels depending on the magnitude of the...

Effects of the insecticide dieldrin on benthic algae in laboratory streams

Creator:: Rose, Frederick Louis
Abstract:: The accumulation of dieldrin and its effects on species composition of benthic algal communities were studied in laboratory streams. Effects of dieldrin on photosynthetic and respiratory rates of the blue-green alga Phormidium retzii were determined using a Gilson Differential Respirometer. Dieldrin concentrations ranging from 0.05 to 7.0 ppb were maintained...
