Effects of esfenvalerate on native macroinvertebrates representative of Pacific Northwest streams

Creator:: Johnson, Katherine R.
Abstract:: Aquatic insects are essential components of healthy stream ecosystems, contributing to nutrient cycling, trophic dynamics and other ecological functions. Aquatic insect species, particularly those in the orders Ephemeroptera, Plecoptera and Trichoptera (EPT taxa) are however, extremely sensitive to insecticide contamination. Given that urban and agricultural use of synthetic pyrethroid insecticides...

Change detection of land cover in a meadow landscape : the“Ranches” meadow, Silver Falls State Park, Oregon

Creator:: Anderson, Carl G.
Abstract:: From a landscape ecology perspective, meadows are often seen as landscapes in transition. Succession and change in meadows may be investigated by considering the physical and anthropogenic factors that influence the landscape through time. What is often unknown is how changes occur and how physical and anthropogenic factors contribute to...

Abstract:: Modern upwelling conditions and corresponding oceanographic properties are investigated and reconstructed for the Late Quaternary. The oceanographic conditions considered influence diatom ecology and the record of fossil diatom frustules in the sediments. Diatoms from modern sediments are evaluated as paleoceanographic proxies and transfer functions (TFs) are calibrated using the Imbrie...

Abstract:: Mule deer (Odocoileus hemionus), elk (Cervus elaphus), and cattle share rangelands throughout much of interior western North America. Considerable debate exists about the degree to which facilitation or competition occurs for forage between these three species (Nelson 1982, Wisdom and Thomas 1996, Miller 2002).

Development of a hybrid modeling framework for intensively managed Douglas-fir plantations in the Pacific Northwest

Creator:: Weiskittel, Aaron R.
Abstract:: Forest growth models in the Pacific Northwest are predominantly empirical. Predictions of yield under alternative silvicultural regimes cannot rely completely on field trials; yet empirical growth models are often inadequate for extrapolating untested regimes and genotypes. The limitations of current models include (1) long time-steps (e.g. 5-10 years); (2) insufficient...

Functions and regulation of cytokinin glucosyltransferases

Creator:: Pineda Rodó, Albert
Abstract:: Cytokinins can be conjugated to N- and O-glucosides. While N-glucosylation generally leads to irretrievable loss of activity, O-glucosides are thought to play an important role in cytokinin storage and homeostasis since they can be hydrolyzed to the corresponding aglycones. The first zeatin O-glycosyltransferase genes isolated were ZOG1 and ZOX1 from...

The nonlinear optical properties of gallium arsenide pertaining to terahertz generation

Creator:: Hurlbut, Walter C.
Abstract:: Gallium arsenide shows excellent promise for terahertz generation using mid infrared. This is for two reasons. First, the indices of refraction for the terahertz (nTHz=3.61 at 1 THz) and mid infrared (nopt=3.431 at 2 μm) are close allowing a long interaction length. Second, the linear absorption is low at terahertz...
