Biological control of spider mites (Acari: Tetranychidae) on grape emphasizing regional aspects

Creator:: Prischmann, Deirdre A.
Abstract:: During summer of 1998 and 1999, 34 and 10 vineyard sites, respectively, were sampled to assess spider mite pests and associated biological control by phytoseiid mites. Vineyards studied spanned five major valleys in western Oregon where grape production occurs. Leaf samples were taken from site perimeters and centers. One leaf...

Effects of grazing management and tree planting pattern in a young Douglas-fir argoforest

Creator:: Carlson, Deirdre H.
Abstract:: A silvopastoral system using a Douglas-fir (Pseudotsuga menziesii) tree crop and subclover (Trifolium subterraneum) as a nitrogen-fixing forage crop was investigated near Corvallis, Oregon, during 1983-1985. Treatments included all possible combinations of three planting patterns (no trees, trees planted 2.5 m apart in a grid, and clusters of five trees...

High-resolution estimates of net community production and air-sea CO₂ flux in the northeast Pacific

Creator:: Lockwood, Deirdre, Quay, Paul D., Kavanaugh, Maria T., Juranek, Lauren W., and Feely, Richard A.
Abstract:: Rates of net community production (NCP) and air-sea CO₂ flux in the Northeast Pacific subarctic, transition zone and subtropical regions (22°N–50°N, 145°W–152°W) were determined on a cruise in August–September 2008 by continuous measurement of surface values of the ratio of dissolved oxygen to argon (O₂/Ar) and the partial pressure of...

... as Forage in the Ecosystem: The Demand for Ecosystem Valuation

Creator:: Lee, Min-Yang, Deroba, Jonathan, Gaichas, Sarah, Feeney, Rachel G., Boelke, Deirdre, and Irwin, Brian
Abstract:: Birds, mammals, and fish eat Atlantic Herring. For the first time, fisheries managers in New England are explicitly considering these, and other, predators when setting harvest control rules for the Atlantic Herring fishery. Based on single-species biological reference points, the herring stock is currently well above MSY levels. However, management...

Physicochemical and biological controls on primary and net community production across northeast Pacific seascapes

Creator:: Kavanaugh, Maria T., Emerson, Steven R., Hales, Burke, Lockwood, Deirdre M., Quay, Paul D., and Letelier, Ricardo M.
Abstract:: The subarctic-subtropical transition zone in the North Pacific represents the second largest sink of atmospheric carbon dioxide in the world ocean, yet the relative importance of physical and biological processes in this uptake is debated. In a step toward understanding the spatiotemporal variability of environmental, physiological, and ecological factors that...

Ambulatory and aerial dispersal among specialist and generalist phytoseiid mites

Creator:: Jung, Chuleui
Abstract:: Specialist and generalist phytoseiid mites are widely used for biological control of spider mites. Understanding dispersal attributes of these mites is important to implementing more stable, cost-efficient integrated pest management. In this regard, we studied dispersal of phytoseiid mites from a local ambulatory phase of movement within a prey patch...

Realizable Path Planning and Execution for Robotic Systems

Creator:: Jones, Dylan A.
Abstract:: Performing autonomous robotic tasks in the field, such as ocean monitoring and aerial surveillance, requires planning and executing paths in dynamic environments. In these uncertain and changing environments, it is not uncommon to see a large difference between the path planned by the robotic vehicle and the path that the...
