Irrigation and Fertigation with Drip and Alternative Micro Irrigation Systems in Northern Highbush Blueberry

Creator:: Vargas, Oscar L., Bryla, David R., Weiland, Jerry E., Strik, Bernadine C., and Sun, Luna
Abstract:: The use of conventional drip and alternative micro irrigation systems were evaluated for 3 years in six newly planted cultivars (Earliblue, Duke, Draper, Bluecrop, Elliott, and Aurora) of northern highbush blueberry (Vaccinium corymbosum L.). The drip system included two lines of tubing on each side of the row with in-line...

Genetic variation in adaptive traits and seed transfer zones for Pseudoroegneria spicata (bluebunch wheatgrass) in the northwestern United States

Creator:: St. Clair, John Bradley, Kilkenny, Francis F., Johnson, Richard C., Shaw, Nancy L., and Weaver, George
Abstract:: A genecological approach was used to explore genetic variation in adaptive traits in Pseudoroegneria spicata, a key restoration grass, in the intermountain western United States. Common garden experiments were established at three contrasting sites with seedlings from two maternal parents from each of 114 populations along with five commercial releases...

Drought-induced amplification of Saint Louis encephalitis virus, Florida

Creator:: Shaman, Jeffrey, Day, Jonathan F., and Stieglitz, Marc
Abstract:: We used a dynamic hydrology model to simulate water table depth (WTD) and quantify the relationship between Saint Louis encephalitis virus (SLEV) transmission and hydrologic conditions in Indian River County, Florida, from 1986 through 1991, a period with an SLEV epidemic. Virus transmission followed periods of modeled drought (specifically low...

Estimating wind-turbine-caused bird and bat fatality when zero carcasses are observed

Creator:: Huso, Manuela M. P., Dalthorp, Dan, Dail, David, and Madsen, Lisa
Abstract:: Many wind-power facilities in the United States have established effective monitoring programs to determine turbine-caused fatality rates of birds and bats, but estimating the number of fatalities of rare species poses special difficulties. The loss of even small numbers of individuals may adversely affect fragile populations, but typically, few (if...

Diversity and distribution of Frankia strains symbiotic with Ceanothus in California

Creator:: Oakley, Brian, North, Malcolm, Franklin, Jerry F., Hedlund, Brian P., and Staley, James T.
Abstract:: Frankia strains symbiotic with Ceanothus present an interesting opportunity to study the patterns and causes of Frankia diversity and distribution within a particular host infectivity group. We intensively sampled Frankia from nodules on Ceanothus plants along an elevational gradient in the southern Sierra Nevada of California, and we also collected...

Acceptance, Acceptability, and Trust for Sagebrush Restoration Options in the Great Basin: A Longitudinal Perspective

Creator:: Gordon, Ryan, Brunson, Mark W., and Shindler, Bruce
Abstract:: In surveys of residents in three urban and three rural locations in the Great Basin we examined the social acceptability of six management practices showing promise for restoring sagebrush-dominated rangelands. Unlike most studies of range management perceptions that have relied on single measurements, we used longitudinal data from a questionnaire...

A Burning Problem: Social Dynamics of Disaster Risk Reduction through Wildfire Mitigation

Creator:: Charnley, Susan, Poe, Melissa R., Ager, Alan A., Spies, Thomas A., Platt, Emily K., and Olsen, Keith A.
Abstract:: Disasters result from hazards affecting vulnerable people. Most disasters research by anthropologists focuses on vulnerability; this article focuses on natural hazards. We use the case of wildfire mitigation on United States Forest Service lands in the northwestern United States to examine social, political, and economic variables at multiple scales that...

Assessing the Carbon Consequences of Western Juniper (Juniperus occidentalis) Encroachment Across Oregon, USA

Creator:: Campbell, John L., Kennedy, Robert E., Cohen, Warren B., and Miller, Richard F.
Abstract:: Our ability to assess the continental impacts of woody encroachment remains compromised by the paucity of studies quantifying regional encroachment rates. This knowledge gap is especially apparent when it comes to quantifying the impact of woody encroachment on large-scale carbon dynamics. In this study, we use a combination of aerial...

Changes in Local School Policies and Practices in Washington State After an Unfunded Physical Activity and Nutrition Mandate

Creator:: Boles, Myde, Dilley, Julia A., Dent, Clyde, Elman, Miriam R., Duncan, Susan C., and Johnson, Donna B.
Abstract:: Introduction: Policies and practices in schools may create environments that encourage and reinforce healthy behaviors and are thus a means for stemming the rising rates of childhood obesity. We assessed the effect of a 2005 statewide school physical activity and nutrition mandate on policies and practices in middle and high...

Riparian litter inputs to streams in the central Oregon Coast Range

Creator:: Hart, Stephanie K., Hibbs, David E., and Perakis, Steven S.
Abstract:: Riparian-zone vegetation can influence terrestrial and aquatic food webs through variation in the amount, timing, and nutritional content of leaf and other litter inputs. We investigated how riparianforest community composition, understory density, and lateral slope shaped vertical and lateral litter inputs to 16 streams in the Oregon Coast Range. Riparian...
