The effects of copper on predator-prey interactions of fathead minnows (Pimephales promelas) and Daphnia pulex

Creator:

Rohm, Christina M.

Abstract:

Total copper concentrations of 10 [mu]g/l to 100 [mu]g/l appeared to alter the predator-prey interactions of fathead minnows (Pimephales promelas) and Daphnia pulex. The effect of copper concentration on the total amounts of D. pulex consumed over a 12-h period varied with the density of prey stocked hourly in the...

Scale patterns indicate changes in use of rearing habitat by juvenile coho salmon, Oncorhynchus kisutch, from 1955 to 1984 in the Tenmile Lakes, Oregon

Creator:

Gunnarsdottir, Hugrun

Abstract:

This study was designed to provide information about the juvenile life history of coho salmon, Oncorhynchus kisutch, in the Tenmile Lakes in Oregon by 1) classifying scales of spawning fish and outgoing smolts (1+), 2) assessing the contribution of juvenile life history types to the returns of adults (3₂) and...

Effects of kokanee (Oncorhynchus nerka) redd superimposition on bull trout (Salvelinus confluentus) reproductive success in the Deschutes River Basin, Oregon.

Creator:

Weeber, Matthew A.

Abstract:

Oregon's only remaining non-reservoir population of adfluvial bull trout (Salvelinus confluentus) is found in Odell Lake, in the headwaters of the Deschutes River. The population size is unknown, but appears to be quite small. Limited spawning and rearing habitats, combined with the effects of introduced species and other anthropogenic changes...

Robots Against Infectious Diseases : A Technologically Grounded, Human-Centered Exploration

Creator:

Kraft, Kory

Abstract:

Robots have the potential to protect health care workers, provide patient care, and ultimately save lives in infectious disease outbreaks. Nevertheless, infectious disease outbreak scenarios present unique technological and social challenges for robotics. This work explores what robots can and should do in the fight against infectious diseases. We present...

Mapping of quantitative trait loci for malting quality in a winter X spring barley (Hordeum vulgare, L.) cross

Creator:

Oziel, Adeline M.

Abstract:

Making quality and winterhardiness in barley are "ultimate" phenotypes composed of component, quantitatively inherited traits. A 69-point genome map of the seven chromosomes of barley was used, in conjunction with multi-environment phenotypes for grain yield and malting quality, to determine the chromosome locations of quantitative trait loci (QTLs). A combined...

Seasonal and diurnal trends of leaf water potential and stomatal conductance of red alder (Alnus rubra Bong) growing along a density gradient in western Oregon

Creator:

Lu, Shengjun

Abstract:

Three Nelder plots of 3-year-old red alder (Alnus rubra Bong) were used for this study at the Cascade Head Experimental Forest, Oregon in the growing season of 1988 at an elevation of 330 meters. Each Nelder plot represented a range of densities from 238 to 101,219 trees per hectare. The...

Tillering, lodging, dry matter partitioning, and seed yield in ryegrass (Lolium spp.) as affected by the plant growth regulator paclobutrazol

Creator:

Hunter, James L.

Abstract:

Seed yield in ryegrass (Lolium spp.) is the product of the number of fertile tillers per unit area and seed weight per spike at maturity. These components of yield develop through a series of growth stages beginning with tiller bud initiation and finishing with seed filling. Environmental conditions during plant...
