Stated choice random utility frameworks are a valuable tool for eliciting the preferences of fishermen. In typical applications, choice outcomes are known prior to choice selection, which may confound results when outcomes are uncertain. To evaluate the importance of uncertainty in decision making, we applied a contingent sequential stated choice...
This guide covers key nutrient management topics related to tall fescue grown for seed in western Oregon. Crop growth and timing of nutrient uptake is covered. Specific recommendations for nitrogen, phosphorous, potassium, sulfur, and soil pH provided. A number of appendices address micronutrients, and other research projects that are relevant...
Discusses nutrient management and fertilizer recommendations for lime, nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, chloride, and micronutrients on annual ryegrass grown for seed. Includes discussion of research and explanation of nutrient management recommendations.
Family forest owners (FFOs) control a majority of private forestland in the United States and have widely diverse ownership and management objectives. Many FFOs manage their holdings for timber production and, thus, are concerned with issues such as reforestation incentives and tax treatment of timber revenues. Their actual knowledge of...
In Earth science, we must often collect data from sensors installed in remote locations. Retrieving these data and storing them can be challenging. Present options include proprietary commercial dataloggers, communication devices, and protocols with rigid software and data structures that may require ongoing expenses. While there are open-source solutions that...
Understanding the causes and consequences of rapid environmental change is an essential scientific frontier, particularly given the threat of climate-and land use-induced changes in disturbance regimes. In western North America, recent widespread insect outbreaks and wildfires have sparked acute concerns about potential insect-fire interactions. Although previous research shows that insect...
This study investigated the spatial distribution of juvenile North Pacific albacore (Thunnus alalunga) in relation to local environmental variability
[i.e. sea surface temperature (SST)], and two large-scale indices of climate variability, [the Pacific Decadal Oscillation (PDO) and theMultivariate
El Nino/Southern Oscillation Index (MEI)]. Changes in local and climate variables were...
BACKGROUND: Cell lineage-specific DNA methylation patterns distinguish normal human leukocyte subsets and can be used to detect and quantify these subsets in peripheral blood. We have developed an approach that uses DNA methylation to simultaneously quantify multiple leukocyte subsets, enabling investigation of immune modulations in virtually any blood sample including...
Potential for large prairie remnants to provide habitat for grassland-obligate wildlife may be compromised by
nonsustainable range-management practices. In 1979–1980, high nesting densities of 3 species of hawks in the genus
Buteo—Ferruginous Hawk (Buteo regalis), Red-tailed Hawk (B. jamaicensis), and Swainson’s Hawk (B. swainsoni)—were
documented on the Zumwalt Prairie and...
