Quality of bluebunch wheatgrass (Agropyron spicatum) as a winter range forage for Rocky Mountain Elk (Cervus elaphus nelsoni) in the Blue Mountains of Oregon

Creator:: Bryant, Larry Duane
Abstract:: This research was conducted on three study areas on elk winter ranges in Northeast Oregon. One was on the Starkey Experimental Forest and Range and the others were in the same vicinity. Plant appendages, spring and fall defoliation and fall growth of bluebunch wheatgrass were evaluated in terms of quality...

An evaluation of understory vegetation dynamics, ecosystem resilience and state and transition ecological theory in an eastern Oregon ponderosa pine forest

Creator:: Carr, Craig A.
Abstract:: Relatively recent increases in ponderosa pine abundance have effected unprecedented changes to ecosystem structure and function. Efforts to restore ponderosa pine systems are often focused on the manipulation of tree structure and the re-introduction of a more natural fire regime. Successful restoration should also incorporate understory components but information addressing...

Water management in the North Deschutes unit irrigation district : geographic perspectives and remote sensing applications

Creator:: Nellis, M. Duane
Abstract:: The North Unit irrigation District of Central Oregon, a water project developed under the guidelines of the Bureau of Reclamation, is characterized by limited water and the need for efficient utilization and control of the irrigation system. To manage the limited water resource, irrigators need a timely and economical method...

Seasonal floodplain wetlands as fish habitat in Oregon and Washington

Creator:: Baker, Cynthia F.
Abstract:: To begin to understand freshwater seasonal floodplain fish communities in the context of human alteration of the physical system, species introductions and wetland restoration efforts, I studied fish assemblages in fifteen seasonal floodplain wetlands within four geographic regions (coastal, upper Columbia River estuary, Puget Sound and eastern Oregon/Washington) in the...

Ova tranfers in sheep and rabbits : studies on material influences and irradiation damage

Creator:: Hunt, William Lynn
Abstract:: The first study utilized ova transfer in sheep and involved hormonal treatments for synchronization of estrus and superovulation in an investigation of crossbred maternal influences on inbred and linecross lambs. Synchronization of estrus in ewes was achieved effectively with either oral progestogen, 6 α-methyl-17α-hydroxy-progesterone acetate (60 mg./ewe/day), or intramuscular injections...

A numerical analysis of ice fog produced by automobiles

Creator:: Nelson, William George
Abstract:: A model of an exhaust plume was developed and programmed on a digital computer. The purpose of the model was to predict the concentration and size distribution of ice particles produced from automobile exhaust during arctic conditions. The model accounted for the nucleation, growth, and freezing of the condensed water...

Sedimentary texture--a key to interpret deep-marine dynamics

Creator:: Allen, David William
Abstract:: The processes responsible for transporting and depositing thick sections of coarse-grained terrigenous clastics on the abyssal floor and for forming associated sedimentary structures are still conjectural. Many workers attribute coarse deep-sea sediments and their probable lithified equivalent, the graywackes of flysch deposits to some type of density movement. Deductions concerning...

Evaluating Multi-objective Trade-offs in Mature Douglas-fir (Pseudotsuga menziesii) Stands of Western Oregon

Creator:: Williams, Neil G.
Abstract:: Contemporary forest management involves a more extensive and diverse suite of management objectives than was the case throughout much of the Twentieth Century. Heightened public and political awareness of local and global biodiversity decline, and interest in arresting these trends, has increased the emphasis on broad-based biodiversity conservation as an...
