Organically certified Northern Highbush Blueberry (NHB; Vaccinium corymbosum L.) production in the Columbia Basin region of Oregon and Washington is expanding. Soils in the region are typically calcareous and highly alkaline, often requiring pH adjustment to an ideal range of 4.5–5.5 to support the establishment of the acid-loving, ericaceous crop....
The rates of biological introductions and invasions are increasing, driving up the associated harms to ecosystems and economies.

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,...
In the process of building international water policies and management institutions, like international treaties and River Basin Organizations, States simultaneously signal the values that they view as most important in these different institutions. Examining expressed and acted-upon values for transboundary freshwater management are currently under-explored areas where overlapping lenses of...
European hazelnut (Corylus avellana L.) is a diploid with 11 pairs of chromosomes (2n = 2x = 22), monoecious, dichogamous and wind-pollinated. Eastern filbert blight (EFB) caused by Anisogramma anomala is a serious disease of European hazelnut (Corylus avellana) in North America, and infection leads to cankers that girdle branches...
Gray wolves are essential keystone species that regulate a biological ecosystem. (Estes, Terborgh, Brashares, Power, Berger, Bond and Wardle, 2011) There are many reasons why maintaining a healthy population of keystone species in the wild is essential. Gray wolves: 1) Are family pack animals that work together as a team,...
