Investigating Influences of Natural and Anthropogenic Lead Sources on Environmental Archives at Multiple Spatial and Temporal Scales: Evidence from Oysters and Ice Cores

Creator:: Wensman, Sophia M.
Abstract:: Environmental archives provide records of natural and anthropogenic variation in the environment at different temporal and spatial scales. Lead (Pb) concentrations and isotopic ratios are useful tracers of anthropogenic emissions from industrial activities including mining, smelting, and leaded gasoline use, however, methods of measuring Pb are largely limited in low...

How Nearshore Currents affect Larval Dispersal and Genetic Connectivity of China Rockfish (Sebastes nebulosus) Along Oregon and Washington Coasts

Creator:: Avila, Alexandra M.
Abstract:: Connectivity of fish populations is a crucial question for fisheries conservation and the development of spatial management plans. Both adult and larval movement define the extent and direction of ecological and evolutionary overlap between geographic regions and, therefore, how we define stocks for management purposes. Within that context, my work...

Beached Bones: Exploring the Genetic Impact of Exploitation on the Diversity of Great Whales in the South Atlantic

Creator:: Sremba, Angela L.
Abstract:: Commercial whaling during the 20th century drastically reduced many populations of great whales in the Southern Hemisphere. The Antarctic blue whale, for example, is estimated to have been reduced to less than 0.1% of its original abundance based on catch records and population dynamic models. Despite this population bottleneck, several...

Long Term Trends and Sources of Sound in United States Waters

Creator:: Haver, Samara M.
Abstract:: Passive acoustic monitoring is a valuable tool for observing the status of marine environments. Comparisons of underwater soundscapes over temporal and spatial scales can provide data to inform marine conservation efforts, including protection of threatened and endangered species. This dissertation utilizes passive acoustic data collected via a broadly spaced array...

Influence of Novel Ocean Conditions on Life History Characteristics of a Nearshore Rockfish with Implications for Population Assessment and Management

Creator:: Rosemond, Rebecca C.
Abstract:: The California Current Large Marine Ecosystem (CCLME), located on the eastern boundary of the North Pacific Ocean, is highly dynamic, with variable conditions driven by seasonal upwelling, regional oceanography, and broad scale climate patterns. In the last decade, the northeast Pacific Ocean has experienced several marine heatwaves (MHWs), prolonged periods...

Response Sensitivity Formulations for Geometrically Nonlinear Finite Element Analysis

Creator:: Al-Aukaily, Alabbas
Abstract:: Significant amounts of uncertainty owing to both modeling decisions and inherent randomness are present in simulating the material and geometric nonlinear response of structural systems to extreme loading. Computing the sensitivity of structural response with respect to model parameters indicates which parameters have the largest affect on the response, which...

The Ecophysiology of Thiamine Deficiency Complex : Evaluating Sources of Thiaminase in Great Lakes Food Webs

Creator:: Evans, Allison N.
Abstract:: Thiamine (vitamin B₁) is required by all living organisms for carbohydrate metabolism and synthesis of amino acids. Thiamine deficiency is responsible for several related classes of early life stage mortality disorders in salmonines, including Thiamine Deficiency Complex (TDC) in the Laurentian Great Lakes, Cayuga Syndrome in the Finger Lakes, and...

Geneticist L.C. Dunn : politics, activism, and community

Creator:: Gormley, Melinda (Melinda Brooke)
Abstract:: L. C. Dunn (1893-1974) spent most of his scientific career conducting research in developmental genetics as a member of the Zoology Department at Columbia University in the City of New York. He had an accomplished scientific career researching mutations in mice, which earned him respect from other geneticists and scientists....

Monte Carlo simulations of magnetic semiconducting Superlattices

Creator:: Scott, Silas Menlo
Abstract:: Computer simulations invoking the Metropolis Algorithm and Monte Carlo techniques were constructed to model the behavior ofvarious systems of magnetic semiconductors. Among the systems modeled were bulk type II FCC antiferromagnets and simple cubic thin films and superlattices. Studies of bulk antiferromagnets revealed dependence of Neel Temperature on nearest neighbor...

Investigating the Quality Dynamics of American Aroma Hops Intended for Dry-Hopping Beer

Creator:: Lafontaine, Scott R.
Abstract:: Historically, brewers have used dry-hopping (a cold extraction of nonvolatile and volatile chemicals from hops into fermenting or finished beer) to increase the microbial stability and shelf life of their beer. As hoppy beer styles have gained in popularity over the last decade (2007-2017), the objective of dry-hopping has turned...
