Subterranean clover yield and nutrient content as influenced by soil molybdenum status

Creator:: Bhella, Harbans Singh
Abstract:: During the Spring of 1969, 47 surface soil samples (0 to 15 cm) as well as foliage samples of subterranean clover were collected from 32 selected western Oregon pastures, in an effort to determine their molybdenum status and to evaluate the use of anion exchange resin method as a means...

Population dynamics of the cinnabar moth, Tyria jacobaeae (Lepidoptera: Arctiidae)

Creator:: Isaacson, Dennis
Abstract:: The dynamics of a field population of the cinnabar moth, Tyria jacobaeae L., were studied near Jordan, Linn County, Oregon. In both 1970 and 1971 larval populations were so large that all foliage of the host weed, tansy ragwort, Senecio jacobaea L., was consumed. The ensuing starvation accounted for the...

Metabolic adaptations of the marine gastropod Thais emarginata

Creator:: Sweat, Sister Jean
Abstract:: Thais emarginata is a gastropod which inhabits the midlittoral zone of the intertidal region. Oxygen consumption of high-level and low-level organisms was determined at various seasons of the year over an experimental temperature range of 5 to 20° C. No significant difference in respiratory rate between separate populations of high-level...

Influence of marine environment on age and size at maturity, growth, and abundance of chum salmon, Ohcorhynchus keta (Walbaum), from Olsen Creek, Prince William Sound, Alaska

Creator:: Helle, John H.
Abstract:: Effects of the marine environment on age and size at maturity, early marine growth, and abundance of chum salmon, Oncorhynchus keta, were studied at Olsen Creek during 1959-77. Chum salmon returned to Olsen Creek as predominately 3-, 4-, and 5-year fish; however, age composition varied from year to year. The...

A genetic study of the red-band trout (Salmo sp.)

Creator:: Wilmot, Richard L.
Abstract:: A group of trout that reside in streams of the desiccating lake basins of southeastern Oregon differ markedly from other known Salmo. Known commonly as the red-band trout, this fish was subjected to chromosome analysis for comparison with other species of western North American Salmo. The karyotype of the red-banded...

The MOS tetrode transistor

Creator:: Limvorapun, Thawee
Abstract:: The MOS tetrode transistor is studied in this project. This device is ideally suited for high frequency and switching application. In effect it is the solid state analogy of a multigrid vacuum tube performing a very useful multigrid function. A new structure is developed for p-channel 10 ohm-cm. silicon substrate...

Heat energy exchange between the Killdeer, its eggs, and the environment

Creator:: Cronan, James Zan
Abstract:: The vegetation surrounding a nest shades and insulates the incubating bird in addition to concealing it. The vegetative material that makes up a nest insulates the eggs from its warmer or cooler surroundings. Since a Killdeer builds a stone-lined nest on barren ground, both egg and adult are subject to...

Vaccination studies with bovine adenovirus type 3 in a dairy calf herd

Creator:: Wangelin, James Richard
Abstract:: In October 1977, a study was undertaken to determine the role of bovine adenovirus type 3 in enzootic pneumonia of calves, and the efficacy of using a vaccine for prevention of disease. Bovine adenovirus type 3 was isolated from the herd under study in the previous year. Calves in the...

Habitat factors affecting pronghorn use of playas in south central Oregon

Creator:: Good, James Ronald
Abstract:: Pronghorn (Antilocapra americana) use of four playas (intermittent lakebeds) on Hart Mountain National Antelope Refuge (NAR) in south central Oregon was studied during the summers of 1974 and 1975. Percent canopy cover of playa vegetation, plant phenology, percent desiccated vegetation, soil moisture, available surface water and pronghorn use of range...
