Abstract:: Epiphytic diatom assemblages in the intertidal zone of Yaquina Bay and estuary were obtained from the following host macrophytes: Zostera marina, Fucus evanescens, and species of Enteromorpha, Polysiphonia, and Ulva. Samples were collected in September 1970 and in January and May 1971 from seven stations approximately evenly spaced between the...

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...

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...

Creator:: Wulff, Barry Lee
Abstract:: Effects of light intensity, exposure to desiccation, reduced salinity, and thermal elevation on the functional and structural characteristics of marine benthic diatom communities were investigated in a laboratory model ecosystem and a respirometer chamber. Measurements of biomass (dry weight and ash-free dry weight) and chlorophyll a were made for each...

Creator:: Berglund, Lisette Aline
Abstract:: Successional patterns of attached estuarine diatoms were investigated using laboratory model ecosystems. Artificial substrates of acrylic plastic were exposed to 0, 4, and 10 hours of desiccation per day. Diatom assemblages that developed under temperatures normal for Yaquina Bay, Oregon (control ecosystem) were compared to assemblages that developed at temperatures...
