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...

William Keith Brooks (1848-1908) : a case study in morphology and the development of American biology

Creator:: Benson, Keith Rodney
Abstract:: The major historical studies that have examined American biology have emphasized the development of experimental biology at the end of the nineteenth century. In this characterization, the descriptive branch of biology has often been treated as less than important and, in several cases, as a hindrance in the application of...

The marine biological station of San Diego : its development as related to the ideas and ideals of William Emerson Ritter (1856-1944)

Creator:: Alexander, Gail Marie
Abstract:: A number of historians of science have been involved in studying the nature of biology at the turn of the century, and the picture that they have developed describes biology during this time as a field struggling to define itself. During the late nineteenth and early twentieth centuries, biologists were...

An evaluation of two methods for determinations of polynuclear aromatic hydrocarbons in water

Creator:: Schaffer, Randy Lee
Abstract:: Research has been completed that evaluates two methods for the extraction of polynuclear aromatic hydrocarbons (PNAH) from water. The two methods compared were EPA Method 610, a liquid-liquid extraction method, and a method involving PNAH adsorption on commercially available short C₁₈ bonded phase columns, Sep-Paks, in series with glass microfiber...

Deposition and persistence of polynuclear aromatic hydrocarbons after slash burning clear-cut sites in Oregon

Creator:: Sullivan, Timothy Joseph
Abstract:: Research has been completed which identifies qualitatively and quantitatively the deposition, persistence and fate of polynuclear aromatic hydrocarbons (PNAH) on burned clear-cut sites in Oregon. Eight PNAH were identified and quantified in post-burn litter samples taken from four slash-burned sites. Deposition of lower molecular weight, 3-4 ring compounds was considerably...

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...

Physiological and hematological changes in chum salmon (Oncorhynchus keta) infected with erythrocytic necrosis virus

Creator:: Haney, Dennis C.
Abstract:: Chum salmon (Oncorhynchus keta) were artificially infected with erythrocytic necrosis virus (ENV) to study the physiological and hematolgical consequences of ENV-infection. Infected and control fish were held in pathogen-free seawater and sampled weekly for five weeks. Physiological tests included plasma cortisol, glucose, protein, and osmolality, blood lactic acid, and liver...

The accumulation of cadmium, copper and nickel in freshwater mussels (Margaritifera margaritifera), algae (Cladophora sp.), and sediment from Elk Creek, Oregon

Creator:: Sigismondi, Linda A.
Abstract:: Concern about heavy metal pollution has increased during the past decade in which studies have shown that heavy metals are accumulating in the environment and that these metals, in excess, are toxic to organisms, including man. Because of this concern, scientists have suggested the use of indigenous organisms as monitors...

Development of a system to test for the toxicity of solar irradiated polynuclear aromatic hydrocarbons and preliminary data using mammalian cell cultures

Creator:: McNair, Vannin Marie Hutchinson
Abstract:: Polynuclear aromatic hydrocarbons (PNAH) classified as noncarcinogens may be photooxidized to mutagenic or toxic products by near-ultraviolet (NUV) wavelengths of sunlight (290-320 nm). The possibility that this represents a major degredation pathway in the aquatic environment is of increasing concern. Large quantities of PNAH from accidental oil spills, anthropogenic and...

Uptake and retention of technetuim [i.e. technetium] by two freshwater species, the crayfish Pacifastacus leniusculus and the snail Juga silicula

Creator:: McKenzie-Carter, Michael A.
Abstract:: The patterns of uptake, retention, and tissue distribution of ⁹⁵mTc in two freshwater species, the crayfish Pacifastacus leniusculus and the snail Juga silicula have been investigated. The animals were chronically exposed in water to which sodium pertechnetate had been added. Final whole-body concentration ratios (CR) obtained were 1.6 and 41...
