Несколько видов ягодных культур коммерчески выращивают в штате Орегон, в том числе, летом плодоносящие и плетье-плодоносящие малины (красная и черная) и ежевика то есть ажина. Эта публикация направлена на оценку содержания и внесения питательных веществ, применяющихся в выращивании кустарных ягод в западной части Орегона.
The federally threatened northern spotted owl (Strix occidentalis caurina) is the focus of intensive
conservation efforts that have led to much forested land being reserved as habitat for the owl and associated wildlife
species throughout the Pacific Northwest of the United States. Recently, however, a relatively new threat to spotted...
Rising atmospheric [CO₂], cₐ, is expected to affect stomatal regulation of leaf gas-exchange of woody plants, thus influencing energy fluxes as well as carbon (C), water, and nutrient cycling of forests. Researchers have proposed various strategies for stomatal regulation of leaf gas-exchange that include maintaining a constant leaf internal [CO₂],...
Faculty and librarians agree on the qualities of a good research question. However, in an exploratory study, they differed on when students should develop their research question. While librarians stated that students should develop their question early, first-year writing faculty advocated for delaying the development of the research question. The...
1. Chronic infections may have negative impacts on wildlife populations, yet their effects are difficult to detect in the absence of long-term population monitoring. Brucella abortus, the bacteria responsible for bovine brucellosis, causes chronic infections and abortions in wild and domestic ungulates, but its impact on population dynamics is not...
Critical information for evaluating the effectiveness of management strategies for species of concern include distinguishing seldom occupied (or low-quality) habitat from habitat that is frequently occupied and thus contributes substantially to population trends. Using multi-season models that account for imperfect detection and a long-term (1981-2002) dataset on migratory Arctic Peregrine...

Reproductively and geographically isolated populations of predators may be synchronized by a phenomenon known as the Moran effect—specifically if they exhibit common responses to external processes, such as climate, density dependence (parasites, disease), or prey. Prey has the ability to synchronize predators if geographically isolated predator populations target the same...
