Predicting the spatial variability in soil properties using DSM across Malheur National Forest

Creator:: Seeno, Elizabeth A.
Abstract:: Soil properties may hold the key to improved predictions of soils during digital soil mapping (DSM), which has developed with a focus on environmental factors external to soil. The spatial variability in soil properties was modeled across Malheur National Forest in eastern Oregon as an approach to improve DSM. The...

Reactive polyphenols and dissolved nutrients in a nitrogen-limited headwater catchment, western Cascades, Oregon, USA

Creator:: Rasmussen, Janet K.
Abstract:: In undisturbed N-limited forested catchments, DON may represent over 90% of the total N lost in streams. Some ecologists have suggested that plant-derived reactive polyphenols may be responsible for DON binding and transport because polyphenol-protein complexes are known to precipitate out of solution, bind to mineral surfaces or organic matter...

An evaluation of biological control of Linaria dalmatica with Mecinus janthinus in Oregon

Creator:: Park, Alexander
Abstract:: Dalmatian toadflax (Linaria dalmatica) has become a prolific invasive plant of rangelands in Oregon since its arrival in the early 20th century. In 2001, the Oregon Department of Agriculture initiated a release program promoting the distribution of the stem-boring weevil, Mecinus janthinus as classical biological control agent to reduce densities...

Interactions between ecosystem nitrogen and bedrock control long-term calcium sources in Oregon Coast Range forests

Creator:: Hynicka, Justin D.
Abstract:: Ecosystem nitrogen (N) supply strongly influences the availability and cycling of other essential nutrients in temperate forests, especially calcium (Ca). Short-term additions of N that exceed ecosystem demands often increase dissolved nitrate fluxes and decrease soil pH, which can stimulate soil Ca loss. However, the long-term effects of high N...

The Role of Natural Resources Information in Oregon Legislative Policy-Making; Two Case Studies from the 1991 Legislative Session

Creator:: Brown, Mara Arwyn
Abstract:: This paper focuses on the role of natural resources information in Oregon legislative policy-making, based on the two legislative case studies from the 1991 Legislative Session, surveys conducted of state natural resource agency legislative liaisons, and a review of current literature addressing policy-making and the role of science in policy-making....

Spatio-temporal Patterns and Ecological Drivers of Harbor Porpoise (Phocoena phocoena) off the Central Oregon Coast, USA

Creator:: Holdman, Amanda
Abstract:: The marine environment is under increasing pressure from human activities worldwide, particularly in coastal waters, creating a need to better understand fine-scale distributions of highly mobile species that occur in the area, as they are frequently most threatened. Harbor porpoise (Phocoena phocoena) occur frequently in Oregon’s nearshore habitat, but due...

Growth of Staphylococcus aureus of enterotoxin production in pre-cooked tuna meat

Creator:: Wu, Xulei
Abstract:: Staphylococcus aureus is a human pathogen capable of producing enterotoxins causing staphylococcal food poisoning, one of the most economically important foodborne diseases in the U.S. This pathogen may be introduced to pre-cooked tuna meat used for the production of canned tuna because significant manual handling occurs after cooking of the...

Characterization of pathogenic and non-pathogenic Vibrio parahaemolyticus strains and the antimicrobial activity of fruit juice and fruit extracts against seafood pathogens

Creator:: Du, Jingyi
Abstract:: Vibrio parahaemolyticus is frequently isolated or detected from raw seafoods, especially shellfish. Also, Listeria monocytogenes, Salmonella spp. are pathogens that are frequently found in ready-to-eat (RTE) seafood, such as smoked fish and shellfish, seafood salad, cooked shrimp and crabmeat, and seafood consumed raw. Two studies to improve safety in RTE...

Working relations and marketing channels in the seafood industry: a multi-sector analysis

Creator:: Anderson, Finlay
Abstract:: With indications that fisheries production has plateued at a global capacity of 85 million metric tons in the 1990's, further exploitation of marine stocks on a sustainable basis is unrealistic. Economic development of coastal and regional economies will benefit from new approaches to maximizing benefits from harvested products that include...
