Monitoring and Evaluating the Susceptibility of Colorado Potato Beetle, Leptinotarsa decemlineata Say, against Insecticides in the Columbia Basin of Northeastern Oregon

Creator:: Yang, Pahoua
Abstract:: Potato (Solanum tuberosum L.) is among one of the largest and most important staple food crops in the world. One of the most productive growing potato regions is the USA is the Oregon and Washington Columbia Basin. Both states produce approximately 26% of the USA potatoes in the market. In...

Nature of the inheritance of gluten strength and carotenoid pigment content in winter by spring and durum wheat crosses (Triticum turgidum L. Var. durum)

Creator:: Ammar, Karim
Abstract:: Durum wheat cultivars for North-Eastern Oregon have to be competitive in terms of their yield potential with soft white winter wheat cultivars and meet strict quality requirements of the milling industry. Combining the high yield potential of fall planted durum wheat cultivars which have an acceptable level of winter hardiness...

Establishment of Kura clover for seed with wheat intercrops

Creator:: Snelling, John P.
Abstract:: Kura clover (Trifolium ambiguum M. Bieb.) is slow to establish and has low seed yields the year after establishment. Intercropping a cereal grain during clover seed field establishment could provide additional revenue to seed growers, provided that intercropping did not jeopardize future clover seed yields. Factorial combinations of spring- and...

Paleoclimatic changes revealed by soil carbonate, and stable carbon and oxygen isotopes, Eastern Korinthia, Greece

Creator:: Bruno, Caroline R.
Abstract:: Soil carbonate is used to interpret paleoenvironmental conditions in the Eastern Korinthia, Greece, with the use of stable carbon and oxygen isotopes. The Eastern Korinthia consists of a series of marine terraces ranging in age from ~600 to 70.2 ka. The lateral stratigraphic context of the marine terraces allows the...

Interactions between nitrogen, phosphorus, and molybdenum in forest soils and cyanobacterial lichen in the Oregon Coast Range

Creator:: Marks, Jade A.
Abstract:: Molybdenum is an essential component of biogeochemical cycling, most notably as a component of the nitrogenase enzyme used in biological nitrogen (N) fixation. While the important role of phosphorus (P) in limiting N fixation in ecosystems has been well documented, occurrence and prevalence of molybdenum (Mo) limitation is largely unknown....

An Analysis of Nutrient Depletion in Douglas-fir Forests of the Oregon Coast Range

Creator:: Siah, Kaveh G.
Abstract:: Nutrient limitation constrains tree growth in many managed forests. Nitrogen (N) is the most common limiting nutrient, but high N supply can shift limitation to other nutrients, particularly phosphorus (P) and the base cations calcium (Ca), magnesium (Mg), and potassium (K). As different soil minerals have different capacities to supply...

Improving Best Management Practices for Potato Production in the Columbia Basin : An Evaluation of Essential Oils for Control of Verticillium Wilt and the Fate of Chloride in the System

Creator:: Light, Sarah Elizabeth
Abstract:: Although the potato (Solanum tuberosum L.) is a global crop, few growing regions rival the high yields of the Columbia Basin of Eastern Oregon and Washington. Two research projects were conducted in Hermiston, OR to contribute to best management practices for the region. The first project evaluated the efficacy of...

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 development and decline dynamics of two ectomycorrhizal fungal mat soil microbial communities in response to a reciprocal soil transfer experiment in old-growth Douglas-fir forests

Creator:: Cappellazzi, Jed E.
Abstract:: Ectomycorrhizal fungi (EmF) form symbioses with trees. These symbioses profoundly influence forest ecology. Certain EmF form specialized profusions of hyphae, known as ectomycorrhizal fungal mats (mats) which are visible to the naked eye, alter forest soil biogeochemistry, substantially contribute to soil microbial biomass/respiration and support unique microbial communities. Piloderma and...
