Forest Successional and Disturbance Dynamics in the Southern Blue Mountains of Eastern Oregon

Creator:: Johnston, James D.
Abstract:: The application of modern land management practices beginning at the turn of the 20th century is widely believed to have dramatically transformed forest landscapes of the inland Pacific Northwest. Restoring historical conditions to make forests resilient to future climate and disturbance regimes is a major goal of federal forest managers....

Unraveling the Diagenetic Cycling and Sequestration of Rare Earth Elements (REEs) in Marine Sediments to Understand REE Accumulation in Ancient Shales

Creator:: Yang, Jon
Abstract:: The rare earth elements (REEs) have been established as powerful tracers for a range of physiochemical processes occurring in the natural environment. They also hold significant economic importance as many technological advancements are reliant upon the REEs for their unique magnetic, luminescent, and electrochemical characteristics. In sedimentary settings, understanding the...

Modeling riparian zone processes : biomass production and grazing

Creator:: Korpela, Edwin J.
Abstract:: Seasonal trends in forage production and environmental parameters for five plant community types within a northeastern Oregon riparian zone were described and modeled using correlation and path analysis. Wet meadows produced the greatest amount of herbage biomass, followed by moist bluegrass meadows, gravel bars, forests and dry bluegrass meadows. Trends...

Influence of irrigation and plant population on yield parameters, flower and pod abscission, and photosynthate distribution in snap beans, Phaseolus vulgaris L.

Creator:: Mauk, Craighton Stiles
Abstract:: During 2 seasons effects of high and low irrigation (water applied at -0.6 and -2.5 bars soil water potential, respectively) and density were evaluated on yield parameters and flower/pod development at mainstem nodes 2 and 6 (terminal) of 'Oregon 1604', a determinate snap bean. High and low plant densities were...

Development of a methodology for containership load planning

Creator:: Cho, Doug Woon
Abstract:: Ship turnaround time at a marine containerport is an important measure of the port's efficiency and attractiveness. Both the speed and quality of load planning affect the length of turnaround time considerably. Past attempts at computerizing the load planning function have been unsatisfactory and have not reflected the port's objective...

Interactions of Amphorophora agathonica Hottes with raspberry viruses and resistant red and black raspberry

Creator:: Lightle, Danielle
Abstract:: In recent years, red raspberry production in Washington and British Columbia has been severely limited by a newly emerged virus complex that causes symptoms of crumbly fruit. The complex is comprised of three viruses: Raspberry bushy dwarf virus (RBDV), Raspberry leaf mottle virus (RLMV) and Raspberry latent virus (RpLV). Both...

Beaches, Wine, and Weed: Economic Implications of Land Use Change in Oregon

Creator:: Beasley, W. Jason
Abstract:: The economic analysis of land use decisions provides insight into incentive structures faced by landowners and the impacts of landowner decisions on others. Qualifying and quantifying these incentives and impacts offers insight into the relevant characteristics of decision-making. In turn, this allows the researcher to model and predict land use...

The ecological legacy of Indian burning practices in southwestern Oregon

Creator:: Carloni, Kenneth R.
Abstract:: Two research questions are posed: (1) How have ecosystem conditions changed through time in southwestern Oregon? (2) How have culture-driven and climate-driven processes contributed to ecosystem change in southwestern Oregon? A brief introduction to the Little River study area is followed by a cultural and ecological history of the watershed....
