Leaf nutrient concentration of hardy kiwifruit [Actinidia arguta var. arguta (Siebold and Zucc.) Planch. ex Miq.] was evaluated throughout two growing seasons (2008-2009) for determinate and indeterminate shoots of female ('Ananasnaya') and male vines. While research has been conducted on the more commonly grown fuzzy kiwifruit (A. chinensis var. deliciosa...
Freshwater discharge affects the biogeochemistry of river-influenced nearshore environments by contributing with carbon and nutrients. An increase in human activities in river basins may alter the natural riverine nutrients and carbon export to coastal ecosystems. Along a wide latitudinal range (32° 55'S-40° 10'S), this study explores the role of climate...
Trichodesmium, a major colonial cyanobacterial nitrogen fixer, forms large blooms in NO₃-depleted tropical oceans and enhances CO₂ sequestration by the ocean due to its ability to fix dissolved dinitrogen. Thus, its importance in C and N cycles requires better estimates of its distribution at basin to global scales. However, existing...
Escalating demand for organic blueberries has driven a significant expansion of northern highbush blueberry (NHB; Vaccinium corymbosum L.) production area. This expansion is particularly pronounced in regions of the Pacific Northwest where native soil conditions are sub-optimal for NHB, notably east of the Cascade Mountain Range of Oregon and Washington,...
Spalting fungi show strong potential as natural colorants on a variety of materials, specifically textiles and wood. Four species of spalting fungi are currently utilized in this manner: Scytalidium cuboideum, which produces a red pigment called draconin red, Scytalidium ganodermophthorum, that produces an unknown yellow pigment, and Chlorociboria aeruginosa and...
Cabbage maggot, Delia radicum (Diptera: Anthomyiidae) impacts the production of Brassicaceae crops worldwide. The larva feed on the roots of crops causing reductions in yields due to impaired root function and unmarketability of crops. Chemical and cultural management programs are commonly used to control cabbage maggot with varying rates of...
“Active carbon” is a rapidly cycling soil organic carbon (SOC) fraction that acts as an energy and nutrient source for the microbial community. Dilute permanganate oxidation has been used to measure an “active carbon” fraction with the assumption that permanganate oxidation mimics enzymatic decomposition. Permanganate oxidizable carbon (PoxC) has become...
This study models the household demand for vehicle miles traveled with a focus on the effects from bicycle ridership and transit ridership. Through the use of data from the Oregon Household Activity Survey collected on behalf of the Oregon Department of Transportation, evidence is found that households participating in bicycle...
Breast cancer is the most common cancer among women as it accounts for about 25% of all female cancer cases. Studies have shown that early detection of breast cancer increases the chances of a positive prognosis amongst patients therefore it is crucial to provide accurate diagnosis tools in routine exams....
Due to public and regulatory restrictions, genetic containment technology is critical for research and development of transgenic trees in forestry. A multi-year field trial demonstrated that the RNAi-LFY construct successfully induces sexual sterility in 6K10 poplar (Populus alba) without visible effects on vegetative development. However, its limited number of replicates...
