Metabolic adaptations of the marine gastropod Thais emarginata

Creator:: Sweat, Sister Jean
Abstract:: Thais emarginata is a gastropod which inhabits the midlittoral zone of the intertidal region. Oxygen consumption of high-level and low-level organisms was determined at various seasons of the year over an experimental temperature range of 5 to 20° C. No significant difference in respiratory rate between separate populations of high-level...

Oxygen consumption by Dendroctonus pseudotsugae Hopkins

Creator:: King, Keith Irl
Abstract:: Oxygen uptakes of Douglas-fir beetles collected during November 1969 through April 1970 were measured at different experimental temperatures. The oxygen uptakes of adult beetles increased at each experimental temperature as the seasons progressed from winter to spring. The larval and pupal Douglas-fir beetles, collected in February 1970, had lower oxygen...

Some aspects of the sulfur cycle in tidal flat areas, and their impact on estuarine water quality

Creator:: Ramm, Alan Edmund
Abstract:: A conceptual model of the tidal flat system, emphasizing the sulfur cycle was presented. Measurements were made of the vertical distribution within tidal flat deposits of total aerobic and sulfate reducing bacteria, total sulfides, redox potential, volatile solids, and particle size. Variations in dissolved oxygen and free sulfides in the...

The influence of behavior and water requirements on the distribution and habitat selection of the gray-tailed vole (Microtus canicaudus) with notes on Microtus townsendii

Creator:: Pearson, John Philip
Abstract:: Microtus canicaudus Miller, the gray-tailed vole, was studied in the field and laboratory in order to clarify aspects of the relationship of this species to its habitat. All trapping and sampling was done on permanent pasture land in the William L. Finley National Wildlife Refuge 12 miles south of Corvallis,...

The comparative metabolism of cadmium, mercury and zinc as environmental contaminants in the freshwater mussel, Margaritifera margaritifera

Creator:: Mellinger, P. J.
Abstract:: The uptake, tissue distribution and retention patterns of cadmium, mercury and zinc were examined in the freshwater mussel, Margaritifera margaritifera. All three of these heavy metals are found in the environment. Both cadmium and mercury are toxic at low environmental concentrations. Zinc may also be toxic at low concentrations but...

Effects of fractionated radiation doses on survival times of the newt (Taricha granulosa)

Creator:: Campbell, Carol Lee
Abstract:: This was a study designed to determine the occurrence of recovery from radiation damage in Taricha granulosa. Irradiation with either gamma or x-ray sources in the range of 96-10,000 rads was given. (The mean or median survival times were determined.) Doses were fractionated and the survival times for the same...

A quantitative method for using an inventory of the soil and water resources of the state of Oregon to determine human population carrying capacities for two acceptable qualities of life

Creator:: Karr, Don John
Abstract:: A method was developed for converting the food producing capabilities of Oregon's soils to numerical data from which state and county carrying capacities for human populations could be calculated. Another method was developed for converting the needs for housing and related support construction to numerical data which would consume cultivated...

The effects of tritiated seawater on development of the goose barnacle Pollicipes polymerus

Creator:: Abbott, David Thomas
Abstract:: The purpose of this study was to determine the effects of tritiated seawater (HTO) on selected developmental stages of the goose barnacle, Pollicipes polymerus. Barnacle embryos were cultured in Millipore cytology monitors with HTO concentrations of 0, 10⁻⁵, 10⁻³, 10⁻¹, and 10¹ μCi/ml. After 22 days, hatching was complete and...

The solid state photochemistry and photophysics of a triphenylmethyl dye cyanide

Creator:: Vernier, David L.
Abstract:: Triphenylmethyl dye cyanides have been known to be sensitive to ultraviolet radiation since early in this century. Under appropriate conditions, exposure to uv leads to heteropolar fission of the C-CN bond (photoionization) and intense coloration due to dye formation. Thin homogeneous films of hexahydroxyethyl pararosaniline cyanide in a nylon matrix...
