Two-stage opening of the northwestern basin and range in eastern Oregon : evidence from the Miocene Crane basin

Creator:: Milliard, Justin B.
Abstract:: New data are presented that provide evidence for the onset of extensional deformation in the Northwestern Basin and Range within 1 million years after the eruption of the Steens Basalt at 16.5 Ma. New geologic mapping (1:24,000), stratigraphic sections, and ⁴⁰Ar/³⁹Ar dating of the Crane Basin rocks provide a control...

Monensin and zeranol alone and in combination for growing-finishing steers and growing heifers

Creator:: Wooten, Donald Griffin
Abstract:: Ninety-two spring-born and 76 fall-born steer and heifer calves (Hereford and Angus x Hereford) averaging 188 and 255 kg, respectively, were utilized in a 2x2 factorial arrangement of treatments to study the effects of zeranol and monensin, alone and in combination, on growth rate, feed efficiency and carcass characteristics. After...

'Hysterical preservationists' and 'gouge-and-run bulldozer boys' : the land-use controversy in Idaho’s White Cloud Mountains, 1968-1972

Creator:: Jensen, Erica (Erica Lyn)
Abstract:: Similar to other spectacular scenic areas in the American West, Idaho’s White Cloud Mountains have been a contested landscape since the beginning of the 20th century. Although, legislation was introduced in Congress as early as 1913 to protect the towering mountains of south-central Idaho as a national park, the issue...

The effects of ryegrass straw and monensin on performance of feedlot lambs

Creator:: Shqueir, Adnan Ali
Abstract:: The objectives of this study were to investigate the effects of the by-product, ryegrass straw, and the feed additive, monensin, on the performance of feedlot lambs. Four pelleted rations were fed ad libitum: Ration 1 - 50% barley, 50% alfalfa hay; Ration 2 - 50% barley, 50% alfalfa hay and...

Natural enemies of native bumble bees (Hymenoptera: Apidae) in western Oregon

Creator:: Maxfield-Taylor, Sarah A.
Abstract:: Bumble bees (Hymenoptera: Apidae) are important native pollinators in wild and agricultural systems, and are one of the few groups of native bees commercially bred for use in the pollination of a range of crops. In recent years, declines in bumble bees have been reported globally. One factor implicated in...

Correlation of endophyte toxins (ergovaline and lolitrem B) with clinical disease : fescue foot and perennial ryegrass staggers

Creator:: Tor-Agbidye, John
Abstract:: Endophytic fungi (A. coenophialum and A. lolii) which infect grasses produce ergot alkaloids that serve as the grasses' chemical defenses and enhance the vigor of the grass. Turf-type tall fescue with high endophyte levels has been deliberately developed to produce a greener, more vigorous, pest-resistant turf. Consumption of endophyte-infected grass...

Atlantic Puffin (Fratercula arctica) Foraging Ecology During Marine Heatwave Conditions

Creator:: Kennerley, William L.
Abstract:: Marine heatwaves (“MHWs”) are discrete periods of anomalously warm ocean conditions that can lead to shifts in the distribution and abundance of marine organisms. Low-trophic level, pelagic forage species are frequently among those affected by MHWs, often resulting in considerable impacts upon their predators. In the North Atlantic Ocean, Atlantic...

Environmentally Sustainable Product Design : Understanding the Environmental Impact of Product Function and Product Labeling

Creator:: Ferrero, Vincenzo J.
Abstract:: Using repositories to store product design information can provide additional and extensive design knowledge to the global design community. Using repository data in the design of new products can be especially impactful for DfX design objectives, such as product sustainability, about which many engineering designers have limited knowledge. Furthermore, repositories...
