Variation in the energy density of forage fishes and invertebrates from the southeastern Bering Sea

Creator:: Whitman, Luke D.
Abstract:: The quality and availability of forage fishes and invertebrates can affect the behavior and productivity of predators that rely on these resources. This study measures the proximate composition of forage fishes and invertebrates from the southeastern Bering Sea to estimate prey energy density (quality) using a method that is ecologically...

Reactions of I-(α-pyridyl)-3-buten-1-o1

Creator:: Whitman, James Edgar
Abstract:: The purpose of this project was to study the reactions of 1-(α-pyridyl)-3-buten-1-ol (compound I) and to determine whether or not the products of some of its reactions are quinolizinium salts. Reaction of compound I with bromine or iodine yields halide salts (when no external cooling is applied) instead of the...

Identification of economic, social, and policy factors influencing irrigation district participation in water transactions in the Deschutes Basin

Creator:: Whitman, Cally A.
Abstract:: Surface water in the Deschutes Basin of central Oregon has been largely over allocated since the early 1900s. Therefore, rapid population growth and urban demand for water in the upper Basin lead to an increased reliance on groundwater in the last three decades. The Oregon Department of Water Resources (OWRD)...

Landscape occupancy by free ranging cattle in northeast Oregon

Creator:: Wilson, Kerry D.
Abstract:: Global Positioning System (GPS) and Geographic Information System (GIS) technologies were employed to evaluate cattle occupancy of three landscape attributes on three different grazing allotments administered by the Wallowa Whitman National Forest in Northeast Oregon. Topographic characteristics of slope; 0-4%, 4-12%, 12-35% and >35% were evaluated as well as north...

Public domain withdrawn from mineral entry in Wallowa-Whitman National Forest: a case study

Creator:: Andersen, Steven B.
Abstract:: Since the passage of the mining and mineral leasing laws, a considerable amount of the public domain has been excluded from mineral exploration and development. It has been estimated that as much as fifty-three and sixty-four percent of the public lands have been withdrawn from the jurisdiction of the mining...

Comparing Himalayan blackberry (Rubus armeniacus) management techniques in upland prairie communities of the W.L. Finley National Wildlife Refuge

Creator:: Ensley, Jona L.
Abstract:: Dedicated to the preservation and promotion of many of the nation’s most threatened and endangered species, the W.L. Finley National Wildlife Refuge is highly invested in the management of some of the last remaining upland prairies once prevalent throughout Oregon's Willamette Valley. More than a century of land fragmentation, fire...

A georeferenced digital image analysis of micro-topographic patterns within the Willamette Floodplain Research Natural Area, W. L. Finley National Wildlife Refuge

Creator:: Anderson, Karen L.
Abstract:: The present day vegetation pattern of the Willamette Valley is a result of a long past of human alteration of the landscape. Beginning with aboriginal burning of the grasslands to present day land uses, the vegetation of the valley has been affected by anthropogenic activity. Wet prairie is a vanishing...

Vegetation ecology of Fraxinus latifolia communities in William L. Finley National Wildlife Refuge, Oregon

Creator:: Heinitz, Eric Fajen
Abstract:: Composition and structure of Oregon ash (Fraxinus latifolia) woodlands in the William L. Finley National Wildlife Refuge, Oregon are described. Twenty stands dominated by Fraxinus latifolia were sampled with 500 m2 circular macroplots in which floristic microplot data were collected for plant community synthesis. Plant communities were identified by computer-assisted...

Increasing Vitamin D Levels to Improve Fertilization Rates in Cattle

Creator:: Peixoto de Souza, Vanessa
Abstract:: Recently, an interest in supplementation of vitamin D to improve aspects of health, especially in human fertility, has emerged. However, supplementation of Vitamin D above the minimum required levels to prevent deficiency has yet to be explored in cattle despite evidence for vitamin D receptors in reproductive tissues. The objective...
