Modeling and dating glacier fluctuations and their relation to Pacific Ocean climate

Creator:: Anslow, Faron S.
Abstract:: This thesis presents the results of an investigation into the interactions between the present-day South Cascade Glacier and the former Mauna Kea ice cap at short (annual to centennial) and long (millennial and multimillennial) time scales. To quantify the response of South Cascade Glacier to atmospheric conditions, a surface energy...

The maintenance and stability of the shell color polymorphism in the rocky intertidal gastropod Thais (Nucella) emarginata

Creator:: Davis, Charles Lee
Abstract:: Thais (Nucella) emarginata is a common predatory gastropod of the rocky intertidal system of western North America. It is usually found at low tide on top of its sedentary prey, barnacles and mussels. Thais is also highly polymorphic for shell color, and breeding of isolated females has shown that the...

A quantitative genetic analysis of fitness characters in Tribolium confusum

Creator:: Zirkle, Dave F.
Abstract:: The objective of this study is to assess the quantitative genetic structure of fitness characters in Tribolium confusum flour beetles. Estimates of genetic variation and covariation for a series of fitness components (two measurements of survival, larval weight, development time, fecundity, and female productivity) were obtained from two populations of...

Spatial patterns of fuel management activities and their effects on wildfire behavior

Creator:: Kim, Young-Hwan
Abstract:: Fuel management has been used as an effective local strategy to reduce the undesirable consequences of wildfires. Many efforts toward scheduling of fuel management activities across a broader landscape have been proposed, with the hope of achieving larger landscape-scale management effects. However, scheduling of fuel management treatments across the broader...

Late Cenozoic Climate, Ice-sheet and Earth-surface Evolution Derived from Terrestrial and Marine Sedimentary Archives

Creator:: Bill, Nicholas S.
Abstract:: The goals of this dissertation are centered on understanding changes in Earth surface and climate systems through the use of geologic proxies as records of past changes in these systems. Specifically, this dissertation (1) establishes a new chronology for retreat of the Ross Sea sector of the West Antarctic Ice...

Influence of soil acidity upon nodulation and growth characteristics of Trifolium subterraneum L.

Creator:: Almendras, Angela S.
Abstract:: Previous research had identified four serogroups of Rhizobium trifolii indigenous to Abiqua soil (fine, mixed, mesic, Cumulic Ultic Haploxerolls). Nodulation of subterranean clover (Trifolium, subterraneum L.) by two of the serogroups, 6 and 36, was influenced by the application of CaC0₃ to the soil. The studies described in this thesis...

Influences of nitrogen on carbon dynamics in forest soil and density fractions

Creator:: Swanston, Christopher W.
Abstract:: Application of N fertilizer is a common forest management practice in the Pacific Northwest, yet the long-term influence of fertilization on forest soil properties is not well known. Although elevated N often increases mineralization of C and N from labile organic matter, negative effects have been documented in recalcitrant organic...
