The economics of spatial choice and displacement: case study of the Oregon bottom trawl groundfish fishery

Creator:: Valcic, Branka
Abstract:: To increase the knowledge needed to successfully implement the ecosystem-based approach to fishery management, this dissertation investigates important issues within the economics of choice and the economics of displacement. In particular, a discrete choice model of the fishing location decision in the Newport, Oregon bottom trawl groundfish fishery is estimated...

Addressing the future of water in Oregon : a look at the human and institutional factors shaping Oregon water management

Creator:: Wolters, Erika Allen
Abstract:: Oregon is a state with great social and ecological diversity. Unfortunately however, Oregon's water-rich reputation is more rumor than reality. As with many Western states, Oregon struggles with water scarcity, especially during dry summer months. Recent efforts by the state to develop an integrated water resource strategy (IWRS) to manage...

Comparative genomics of Vibrio and characterizing microbial communities at a shellfish hatchery

Creator:: Delgado, Hanna
Abstract:: Vibrio bacteria are commonly found in freshwater, marine, and estuarine environments. Members of this genus can exist in commensal relationships with marine animals or as planktonic bacteria, however, they are well known for their roles as pathogens towards humans and animals. In this dissertation, I investigated aspects of host-bacteria relationships...

Quantitative, multi-spectral, light-transmission imaging of colloid transport in porous media at the meso scale

Creator:: Kraft, Erika Lorna
Abstract:: Colloids, particles smaller than ten microns in diameter, are ubiquitous in the subsurface. Colloids have an effect on the transport of contaminants that bind to their surfaces, and can reduce the permeability of aquifer materials through deposition. Some microorganisms, including pathogens, are also transported in the subsurface as colloids. The...

Reproductive strategies of the Ocoee salamander, Desmognathus ocoee

Creator:: Adams, Erika M.
Abstract:: The majority of female animals are polyandrous: offspring within a single reproductive event are sired by more than one male. However, we lack a clear understanding of the ultimate causes of polyandry, and of the male reproductive strategies which have evolved in response to selection occurring after insemination. I addressed...

Genomic Resource Development for European Hazelnut (Corylus avellana L.)

Creator:: Rowley, Erik R.
Abstract:: European hazelnut (Corylus avellana L.) is an important crop Oregon's Willamette Valley, producing 99% of the hazelnuts grown in North America and brings over US $60 million dollars to the region annually. Hazelnuts are rich in fiber and vitamins, as well in demand by consumers due to their popularity as...

Investigating the effects of temperature on secondary metabolism in Vitis vinifera L. cv. merlot berries

Creator:: Cohen, Seth D.
Abstract:: Grapes (e.g. Vitis vinifera L.) are one of the more important fruit crops from an economic standpoint with world market values over 550 million US dollars in 2007 and 2008, second to apples (United States Department of Agriculture). While a satisfactory level of ripeness is of primary concern, the quality...

Evaluation of Methods for Applying Phosphorus, Potassium, and Boron Fertilizers in Northern Highbush Blueberry (Vaccinium corymbosum L.)

Creator:: Leon-Chang, David P.
Abstract:: Previous studies indicated that fertigating with nitrogen (N) was more effective than using granular N fertilizers in production of northern highbush blueberry (Vaccinium corymbosum L.). To build on these findings, four studies were conducted in western Oregon to determine whether fertigation was also an effective method for applying other nutrients,...

Crossing behavior, RAPD analysis and chlorophyll flourescence in relationship to the geographic adaption of birdsfoot trefoil (Lotus corniculatus L.)

Creator:: García de los Santos, Gabino
Abstract:: Birdsfoot trefoil (Lotus corniculatus L.) is a popular perennial, non-bloating forage legume used for pasture, hay and silage throughout the temperate regions of Europe, Asia Minor, North Africa and North and South America. It is regarded as the most morphologically and biochemically variable species in the genus. Research investigating the...
