Reproductive isolation and interspecific hybridization in the threatened species, Sidalcea nelsoniana

Creator:: Gisler, Steven D.
Abstract:: In addition to its longstanding recognition as an influential evolutionary process, interspecific hybridization is increasingly regarded as a potential threat to the genetic integrity and survival of rare plant species, manifested through gamete wasting, increased pest and disease pressures, outbreeding depression, competitive exclusion, and genetic assimilation. Alternatively, hybridization has also...

Conservation of Sidalcea nelsoniana through habitat management : effects of burning, mowing, and altered flooding regime on a rare Willamette Valley perennial

Creator:: Bartels, Marilynn R.
Abstract:: Active habitat management plays a key role in the preservation of native ecosystems and rare species, especially in the Willamette Valley of Oregon, where natural succession to woodlands threatens the few wetland prairies remaining after 150 years of agriculture and urbanization. Sidalcea nelsoniana, listed as threatened under the federal Endangered...

Investigation of the Effects of Commercial Salmon Fishery Management in Upper Cook Inlet, Alaska

Creator:: Fleming-Craig, Danielle
Abstract:: Optimal commercial fishery management sustains each salmon species' population while maximizing economic benefits. This thesis addresses two questions. What are the Alaska Department of Fish and Game's and the Board of Fisheries' intentions when conducting a fishery management plan in Upper Cook Inlet? How does it compare to its implementation?...

On Morality, Psychology, and Conservation: An Interdisciplinary Appraisal of Ethics in Context

Creator:: Batavia, Chelsea K.
Abstract:: Conservation is, among other things, the expression of a relationship between humans and nonhuman nature. This relationship can be described empirically using the methods of social science, but it can also be prescribed in the form of philosophical arguments. Scholars in the field of environmental ethics have discussed and debated...

The effects of land use on stream nitrate concentrations : from the catchment scale to the regional scale

Creator:: Poor, Cara J.
Abstract:: This work furthers the understanding of processes occurring in catchments that affect stream nitrate concentrations using two different approaches: a temporally intensive case study of three headwater catchments with varying land use (through storm event monitoring) and a spatially intensive study on the regional scale (through statistical modeling) of 1st-4th...

Estuarine sediment controls on trace metal distributions

Creator:: Davies-Colley, Robert J.
Abstract:: Sediments are the major compartment in aquatic environments for many materials of toxic or nutrient concern. The lack of knowledge of the phase associations of toxic metals in sediments is the largest deficiency in our understanding of the environmental hazard posed by metal contamination. This study examined the sedimentary partitioning...

Silicon biogeochemistry in the open-ocean surface waters : insights from the Sargasso Sea and equatorial Pacific

Creator:: Krause, Jeffrey W.
Abstract:: Diatoms are a ubiquitous group of plankton responsible for 20-40% of oceanic primary production, and a higher fraction of organic matter export to the ocean interior. Diatoms actively transport dissolved inorganic silicon into their cells, and through the process of silicification (i.e. biogenic silica production) they build tough and intricate...

Ecological Forestry : A Critical Analysis

Creator:: Batavia, Chelsea
Abstract:: Although science is widely accepted as a fundamental source of information underlying decisions about forest management and conservation, considerably less attention has been paid to the inevitable role that normative values and beliefs play in such decisions. This thesis highlights the normative dimensions of "ecological forestry," a strategy of forest...
