Analyzing the present and future Pacific-North American teleconnection using global and regional climate models

Creator:: Allan, Andrea M.
Abstract:: In this thesis I present the results of a comprehensive assessment of the Pacific-North American (PNA) teleconnection pattern in general circulation models (GCMs) and a regional climate model (RCM). The PNA teleconnection pattern is a quasi-stationary wave field over the North Pacific and North America that has long been recognized...

Eclipse Ice Core Accumulation and Stable Isotope Variability as an Indicator of North Pacific Climate

Creator:: Kelsey, Eric P., Wake, Cameron P., Yalcin, Kaplan, and Kreutz, Karl
Abstract:: The high accumulation rate and negligible amount of melt at Eclipse Icefield (3017 m) in the Saint Elias Range of Yukon, Canada, allows for the preservation of a high-resolution isotopic and glaciochemical records valuable for reconstruction of climatic variables. Each of the three Eclipse ice cores have a well-constrained depth–age...

Changing Storms and Snowpack Fate in the Western United States

Creator:: Hu, Jyun-Yi Michelle
Abstract:: Cold-season storms are responsible for generating most of the snow that accumulates in mountainous watersheds across the western United States, but with overwhelming evidence of warming temperature trends, this seasonal snowpack is at risk for melt, The vast majority of snow trend studies utilize undifferentiated air temperature records – these...

Deciphering ocean carbon in a changing world

Creator:: Moran, Mary Ann, Kujawinski, Elizabeth B., Stubbins, Aron, Fatland, Rob, Aluwihare, Lihini I., Buchan, Alison, Crump, Byron C., Dorrestein, Pieter C., Dyhrman, Sonya T., Hess, Nancy J., Howe, Bill, Longnecker, Krista, Medeiros, Patricia M., Niggemann, Jutta, Obernosterer, Ingrid, Repeta, Daniel J., and Waldbauer, Jacob R.
Abstract:: Dissolved organic matter (DOM) in the oceans is one of the largest pools of reduced carbon on Earth, comparable in size to the atmospheric CO₂ reservoir. A vast number of compounds are present in DOM, and they play important roles in all major element cycles, contribute to the storage of...

The genome of Aiptasia, a sea anemone model for coral symbiosis

Creator:: Baumgarten, Sebastian, Simakov, Oleg, Esherick, Lisl Y., Liew, Yi Jin, Lehnert, Erik M., Michell, Craig T., Li, Yong, Hambleton, Elizabeth A., Guse, Annika, Oates, Matt E., Gough, Julian, Weis, Virginia M., Aranda, Manuel, Pringle, John R., and Voolstra, Christian R.
Abstract:: The most diverse marine ecosystems, coral reefs, depend upon a functional symbiosis between a cnidarian animal host (the coral) and intracellular photosynthetic dinoflagellate algae. The molecular and cellular mechanisms underlying this endosymbiosis are not well understood, in part because of the difficulties of experimental work with corals. The small sea...

Backbones of evolutionary history test biodiversity theory for microbes

Creator:: O'Dwyer, James P., Kembel, Steven W., and Sharpton, Thomas J.
Abstract:: Identifying the ecological and evolutionary mechanisms that determine biological diversity is a central question in ecology. In microbial ecology, phylogenetic diversity is an increasingly common and relevant means of quantifying community diversity, particularly given the challenges in defining unambiguous species units from environmental sequence data. We explore patterns of phylogenetic...

Trends in streamflow above and below dams across the Columbia River basin from 1950 to 2012 : assessing sub-basin sensitivity

Creator:: Hammond, John C.
Abstract:: Climate change, combined with population growth, is expected to exacerbate water scarcity globally. In the Columbia River basin (CRB), streamflow is managed for multiple objectives with a network of dams and reservoirs distributed throughout the basin that may mitigate climate change effects on water scarcity. This study quantified trends in...

Microstructure of radiation damage in the uranium film and its backing materials irradiated with 136 MeV 136Xe+26, Microstructure of radiation damage in the uranium film and its backing materials irradiated with 136 MeV ¹³⁶Xe⁺²⁶

Creator:: Sadi, Supriyadi
Abstract:: Microstructure changes in uranium and uranium/metal alloys due to radiation damage are of great interest in nuclear science and engineering. Titanium has attracted attention because of its similarity to Zr. It has been proposed for use in the second generation of fusion reactors due to its resistance to radiation-induced swelling....

The effect of climate variation on agro-pastoral production in Africa

Creator:: Stige, Leif Christian, Stave, Jørn, Chan, Kung-Sik, Ciannelli, Lorenzo, Pettorelli, Nathalie, Glantz, Michael, Herren, Hans R., and Stenseth, Nils Chr.
Abstract:: Using national crop and livestock production records from 1961–2003 and satellite-derived data on pasture greenness from 1982–2003 we show that the productivity of crops, livestock, and pastures in Africa is predictably associated with the El Niño Southern Oscillation and the North Atlantic Oscillation. The causal relations of these results are...

Theoretical Prediction of Disrupted Min Oscillation in Flattened Escherichia coli

Creator:: Schulte, Jeff B., Zeto, Rene W., and Roundy, David
Abstract:: The dynamics of the Min-protein system help Escherichia coli regulate the process of cell division by identifying the center of the cell. While this system exhibits robust bipolar oscillations in wild-type cell shapes, recent experiments have shown that when the cells are mechanically deformed into wide, flattened out, irregular shapes,...
