Factors influencing nest success of greater sandhill cranes at Malheur National Wildlife Refuge, Oregon

Creator:: Ivey, Gary L.
Abstract:: I developed a priori hypotheses and used logistic regression to model Greater Sandhill Crane (Grus canadensis tabida) nest success in relation to weather, habitat and management variables for cranes breeding at Malheur National Wildlife Refuge (MNWR) in southeast Oregon. My primary interest was to investigate the effects of habitat conditions...

Cell cycle regulation of DNA precursor accumulation in the yeast Saccharomyces cerevisiae

Creator:: Koc, Ahmet
Abstract:: In budding yeast, many of the genes that encode enzymes required for DNA precursor synthesis (MCB genes) are expressed under cell cycle control in late G1/S. The relationship between MCB gene expression, dNTP synthesis and DNA synthesis was investigated by using α factor-synchronized Saccharomyces cerevisiae. The levels of all four...

DC trains and Pc3s : source effects in mid-lattitude geomagnetic transfer functions

Creator:: Egbert, Gary D., Eisel, Markus, Boyd, O. Sierra, and Morrison, H. Frank
Abstract:: Magnetotelluric (MT) data from two sites 150 and 300 km southeast of San Francisco, California (geomagnetic dipole latitude: 43 degrees, L approximately 1.9) show that the usual MT assumption of spatially uniform external magnetic fields is violated to a significant degree in the period range 10-30 s. Inter-station transfer functions...

Lesser prairie-chicken brood habitat in sand sagebrush: invertebrate biomass and vegetation

Creator:: Hagen, Christian A., Salter, G. Curran, Pitman, James C., Robel, Robert J., and Applegate, Roger D.
Abstract:: Invertebrates are an important food source for grouse chicks, especially within the first 2 weeks of life. Invertebrate abundance is highly patchy and dependent upon herbaceous cover and vegetation structure. We examined the relationship between invertebrate biomass (from sweepnet samples) and habitat structure at lesser prairie-chicken (Tympanuchus pallidicinctus) brood-use and...

Distant effect of assimilation of moored currents into a model of coastal wind-driven circulation off Oregon

Creator:: Kurapov, Alexander, Allen, John S., Egbert, Gary D., Miller, Robert N., Kosro, P. Michael, Levine, Murray D., and Boyd, Timothy John, 1958-2013
Abstract:: An optimal interpolation (OI) sequential algorithm is implemented for a three-dimensional primitive equation model to assimilate current measurements from acoustic Doppler profilers moored on the Oregon shelf as a part of the Coastal Ocean Advances in Shelf Transport (COAST) upwelling experiment (May–August 2001). A stationary estimate of the forecast error...

Mooring observations from the Oregon continental shelf : April-September 1999 : a component of the prediction of wind-driven coastal circulation project

Creator:: Boyd, Timothy John, 1958-2013, Levine, Murray D., Kosro, P. Michael, and Gard, Steve R.
Abstract:: This report documents oceanographic and meteorological measurements made from instruments deployed on four moorings over the continental shelf west of Oregon, from spring through summer, 1999. These moorings were a component of an observational and numerical modeling program to study the response of the coastal ocean to wind forcing. The...

Climate and Fisheries: Costs and Benefits of Change

Creator:: Sharp, Gary D., Klyashtorin, Leonid, and Goodridge, James
Abstract:: Many records provide the bases for a clearer understanding of the roles of climate regime shifts and short-term perturbations in ecosystem dynamics, hence fisheries responses. Too few have taken the long view of the role of humans in this "Grand Fugue". As one of many predators, it is imperative that...

Western larch resistance to Douglas-fir beetle attack

Creator:: Neal, Tiffany A.
Abstract:: Live western larch, Larix occidentalis Nutt., a tree species resistant to the Douglas-fir beetle, Dendroctonus pseudotsugae Hopkins, produces the monoterpene 3-carene in higher concentrations compared to Douglas-fir, the preferred host of D. pseudotsugae (Reed et al. 1986). The inhibitory effects on attraction to aggregation pheromones and toxicity of 3-carene to...

Structure elucidation of bioactive natural products from Madagascar marine algae and cyanobacteria

Creator:: Andrianasolo, Eric Hajaniriana
Abstract:: This thesis is an investigation of the natural products deriving from marine algae and cyanobacteria and has resulted in the discovery of eleven new secondary metabolites. The structure elucidations of these new molecules were performed using a variety of spectroscopic techniques. Four new macrolides were isolated and characterized from the...

Biologically active cyclic depsipeptides from marine cyanobacteria

Creator:: Medina, Rebecca A.
Abstract:: This thesis describes the chemical investigation of marine cyanobacteria collected in Madagascar and Panama with an emphasis on the isolation and structure elucidation of medicinally relevant secondary metabolites. A collection of the marine cyanobacterium Lyngbya majuscula from the Radames Islands, Madagascar yielded two new cyclic depsipeptides, radamamides A and B,...
