Applying a Dynamic Time Warping Approach to Stratigraphic Correlation: Quaternary Magnetostratigraphy and Ediacaran–Cambrian Chemostratigraphy

Creator:: Hagen, Cedric J.
Abstract:: Magneto- and chemostratigraphic correlation underpins much of our understanding of Earth history, yet typical correlation techniques are neither quantitative nor objective. Within this dissertation, I detail my efforts to develop and apply dynamic programming-based algorithms that accomplish optimal and reproducible stratigraphic alignment. I apply these algorithms to three geologic intervals:...

Drug Discovery and Chemical Ecology Investigations of Specialized Metabolism in Tolypocladium and Paraisaria

Creator:: Tehan, Richard M.
Abstract:: Since the discovery of penicillin in 1928, the fungal kingdom has remained a fertile source for the discovery of new, biologically active, natural products. Further, as natural products continue to be discovered from fungi, a deeper understanding of the critical role of specialized metabolism in fungal ecology is afforded. The...

Econometric Analysis of Private Decisions on Renewable Natural Resources

Creator:: Zhao, Zichu
Abstract:: Natural resources play a crucial role in human society by providing both market value and non-market value. Effective management of these resources is necessary to achieve a balance between economic value and other non-market benefits. Econometric studies focusing on natural resource management help us understand the costs and benefits of...

Generalized Preconditioning to Accelerate Simulations with Large Multiphase Chemical Kinetics Models

Creator:: Walker, Anthony S.
Abstract:: Combustion emissions produced from burning real transportation fuels have many environmental impacts. However, detailed chemistry across multiple phases, time scales, and thermodynamic conditions make predicting combustion emissions challenging. Detailed modeling of the gas phase alone is prohibitively expensive, due to the large size and stiffness of the kinetic models. The...

Mycorrhizal Fungi on the Sagebrush Steppe: Benefits for Restoring Keystone Rangeland Plant Species

Creator:: Prado-Tarango, David E.
Abstract:: Arbuscular mycorrhizal fungi (AMF) are plant symbionts that associate with the vast majority of terrestrial plants species. The AMF colonizes the plant roots by penetrating the root cortical cells, where the fungi exchanges mineral nutrients with the host plant for photosynthates. This association exists as a complex system in which...

Environmental and Community Exposures and Children’s Infectious Diseases in Bangladesh

Creator:: Ahmed, Sharia M.
Abstract:: Under-5 mortality has decreased globally, but millions of children still die every year. In Bangladesh, respiratory infection and diarrheal disease remain leading causes of morbidity and mortality for children under-5, despite incredible progress in the past three decades. Immune system development begins in utero and continues into adulthood. Toxic environmental...

The Interaction of Fire Refugia and Climate Refugia: A Case Study within California’s Diablo Mountain Range

Creator:: Turk, Douglas E.
Abstract:: As climate change contributes to larger and more severe wildfires in California, areas of fire refugia – considered unburned and low-severity burn patches – are playing an increasingly important role in sustaining ecosystem resilience, maintaining biodiversity, and supporting post-disturbance recovery. At the same time, climate refugia – which are areas...

The Identification of Common Environmental and Demographic Associations for Tick-Borne Disease Risk and Surveillance Efforts in the United States

Creator:: Ashraf, Benjamin J.
Abstract:: Ixodes scapularis (e.g. blacklegged tick) is a hard-bodied tick considered endemic to certain regions within the United States. This species is considered a primary vector of Lyme disease (Borrelia burgdorferi), anaplasmosis (Anaplasma phagocytophilum) and babesiosis (Babesia microti). Each of these tick-borne diseases represent a growing health concern within the nation...
