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...

Convinced of the divinity of the human body,...
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...
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)...
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...

of the public lands have been withdrawn from the jurisdiction
of the mining...

AN ABSTRACT OF THE THESIS OF
Jona L. Ensley for the degree of Master of Science in
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...
