Studies were conducted to assess influencing the effectiveness of sheep for grazing control of false brome (Brachypodium sylvaticum) an invasive grass species. Orphan lambs were exposed to false brome via grass extract in their milk and naturally reared lambs were exposed by grazing dense stands of false brome with their...
The ionotropic glutamate receptors are ligand-gated ion channels that mediate the majority of excitatory neurotransmission in the brain. The three classes of ionotropic glutamate receptors are alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA), N-methyl-D-aspartate (NMDA), and kainite. These three classes have unique subunits. NMDA receptors play important roles in development, forms of synaptic plasticity,...
Port-Orford-cedar (POC) (Chamaecyparis lawsoniana (A. Murl.) Parl) is an
important tree species native the coastal ranges of southern Oregon and northern
California. The tree is a false-cedar in the cypress (Cupressaceae) family and is used for
timber and planted as an ornamental. The tree in most of its native range...
An analytical method was adapted to extract semi-volatile organic compounds (SOCs) from conifer needles. Needles from Abies concolor
(white fir) and Pinus contortas (lodgepole pine) from Sequoia National Park (SNP) were collected during the summer of 2003, and analyzed for SOCs. The goal of this research was to determine differences...
Five new anti-zebrafish cytochrome P450 (CYP) antipeptide polyclonal antibodies were tested for tissue specificity using immunohistochemistry. The antibodies are for the zebrafish CYPs IA, 2K6, 2K7, 3A65 and 3C1. Three of these antibodies were also compared to existing antibodies made against CYP isozymes in rainbow trout (Oncorhynchus mykiss). Individual staining...
Motivation: It can take considerable amounts of time and effort to use existing computational tools to analyze a small RNA sequence for the purpose of determining if it is characteristic of microRNA. It is similarly tedious to search for homologs to known microRNA sequences in the rapidly growing collection of...
The nursery industry plays a critical role in Oregon's economy. An increase in wood-boring insect, or borer, activity has impacted the industry. The goal of this research is to determine key borer species in the nursery industry, flight times so targeted spray schedules can be established, and assess grower knowledge...
Little is known about upland agricultural grassland soil invertebrate composition and its contribution to ecosystem functioning. Soil-dwelling organisms play a central role in soil formation, plant nutrition, and are significant food contributors for organisms in several trophic levels. Information is needed about mesofauna seasonal population and composition trends throughout the...
