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...

Structure and productivity of marine benthic diatom communities in a laboratory model ecosystem

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...

The distribution of epiphytic diatoms in Yaquina Estuary, Oregon

Creator:: Main, Stephen Paul
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...

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...

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...

Distributional patterns and taxonomic structure of diatom assemblages in Netarts Bay, Oregon

Creator:: Whiting, Mark Carlos
Abstract:: Epiphytic, planktonic and benthic diatom assemblages were investigated in Netarts Bay, Oregon. Samples were collected for a one-year period from February 1980 to March 1981. A planktonic flora was observed only during periods of offshore enrichment when marine neritic species were abundant and were transported into the bay by tidal...

Identifying Differences in the Release of Bioactive Milk Peptides Across the Intestinal Tract Between Term and Preterm Infants

Creator:: Beverly, Robert L.
Abstract:: Premature birth interrupts the typical development of the human fetus, leaving the infant born with underdeveloped gastrointestinal and immune systems. Preterm infants have reduced stomach acidity, reduced digestive protease activity, more permeable intestinal membranes, impaired innate and adaptive immune response, and poor microbiome development. Due to these factors, preterm infants...
