Some possible roles for selenium in the reproductive physiology of the male graytailed vole (Microtus canicaudus)

Creator:: Whitfield, Stephen Curtiss
Abstract:: The testes of the gray-tailed vole (Microtus canicaudus Miller) exhibited a high affinity for selenium relative to other selected tissues. Uptake of selenium-75 in the testis-epididymis complex was delayed relative to uptake by the whole body, kidney, and liver. This pattern of uptake suggested that selenium was metabolically incorporated into...

Influences of salvage logging on forest birds after fire in the eastern Cascades, Oregon

Creator:: Cahall, Rebecca E.
Abstract:: Previous research examining the influences of post-fire salvage logging on abundances of birds has focused primarily on the response of cavity-nesting species. There is limited research in regard to the impact of salvage logging on a broader range of bird species. In addition, little is known about how different intensities...

Influence of movement corridors on enclosed populations of the gray-tailed vole : do immigrants affect reproduction and dispersal of residents in a patchy environment?

Creator:: Davis-Born, Renee
Abstract:: I monitored demography, movement, and reproductive behavior of gray-tailed voles, Microtus canicaudus, in experimental habitat patches with and without corridors. I tested the hypotheses that reproductive rate, juvenile recruitment, and population size and growth rate would be affected negatively by immigrants that were introduced to resident groups (+ male and...

The effects of light on photosynthesis and rooting of leafy cuttings of Pisum sativum L.

Creator:: Davis, Tim D.
Abstract:: The effects of light incident on leafy cuttings is quite complex because' light influences several factors which may affect root formation. One effect of light is to influence the carbohydrate status of the cutting by influencing photosynthesis. The role of current photosynthate in the rooting of leafy cuttings is uncertain....

Diving into Diversity: Fish Populations and Climate Resilience in an Endorheic Basin

Creator:: Dew, Aleah
Abstract:: The Goose Lake Basin, situated on the border of Oregon and California, USA, faces significant challenges from drought, wildfire, and other environmental stressors. This region hosts numerous endemic fish species such as the Goose Lake redband trout (Oncorhynchus mykiss newberri), Goose Lake lamprey (Entosphenus sp.), Goose Lake tui chub (Siphateles...

A block method approach to solving the Laplace equation on a parallel computer

Creator:: Hitchcock, Paula Ann
Abstract:: This paper continues exploration in the area of programming for parallel computers. The appendix to the paper contains an extensive survey of the literature related to parallel computers and parallel programming techniques. The paper itself presents a new approach to solving the Laplace equation on a. parallel computer. A new...

An investigation of bivariate approximations

Creator:: Bills, Gary Royce
Abstract:: The three important methods of approximation; interpolation, least- squares, and Chebyshev, are extended into bivariate approximations. A method of obtaining polynomial approximations for very general classes of bivariate samples is developed. Bivariate least - square approximations are reviewed and a method of developing bibariate orthogonal sequence is derived. A method...

Rigorous computer inversion of some linear operators

Creator:: Yungen, Walter Arthur
Abstract:: In this thesis we consider computer techniques for inverting n X n matrices and linear Fredholm integral operators of the second kind. We develop techniques which allow us to prove the existence of and find approximations to inverses for the above types of operators. In addition, we are able to...
