Creator:: Ivey, Gary L.
Abstract:: California's Central Valley agricultural landscapes provide several important wintering regions for Pacific Flyway sandhill crane (Grus canadensis) populations; however, the value of those regions is being compromised by urban expansion, other developments, and conversions to incompatible crop types. Greater (G. c. tabida) and lesser sandhill cranes (G. c. canadensis) both...

Abstract:: Microplastics are ubiquitous in our oceans, yet we are still clarifying what risks they pose to marine organisms, which can be challenging due to their trait diversity and spatial patchiness. Laboratory-based studies assessing risk demonstrate that many marine animals internalize microplastics, either actively through ingestion or passively via respiration. However,...

Creator:: Shelton, Christopher T.
Abstract:: The lead-zirconate-titanate (PZT) solid solution system is currently the workhorse of piezoelectric-based microelectromechanical systems (MEMS) research. Among bulk materials it is known to be one of the strongest piezoelectrics, with extremely high piezoelectric coefficients and electro-mechanical coupling factors. Reproducing these exceptional qualities in thin film form, however, requires precise tuning...

Creator:: Balbas, Andrea M.
Abstract:: This dissertation uses argon geochronology and cosmogenic nuclide surface exposure dating methods to address three research questions. The first question concerns a geomagnetic instability recorded in lava flows on the island of Floreana in the Galapagos Archipelago. Changes in the Earth’s magnetic field (intensity and orientation) occur frequently throughout geologic...

Creator:: Payne, Meredith C.
Abstract:: The quantification and description of sea surface temperature (SST) is critically important because it can influence the distribution, migration, and invasion of marine species; furthermore, SSTs are expected to be affected by climate change. Recent research indicates that there has been a warming trend in ocean temperatures over the last...

Creator:: Cooley, Richard Bleier
Abstract:: The ferritin-like superfamily (FLSF) of proteins is composed of a wide variety of functionally diverse proteins involved in oxygen dependent metal-mediated electron transfer reactions. Their biological importance is exemplified by the fact FLSF proteins are found in almost every organism from all three domains of life. Their functions range from...

Creator:: Hahlbeck, Nicholas J.
Abstract:: Climate change is a global phenomenon, but natural selection occurs within landscapes. A central tenet of landscape ecology is that mobile species depend on complementary habitats, which are insufficient in isolation, but combine to support animals through the full annual cycle. For coldwater fishes, it is widely assumed that maximum...

Creator:: Ring, Jeffery R.
Abstract:: At the intersection of higher education and politics, there is demand for an easily understood measure of student success. Graduation rate is the current measure of choice, but the definition of graduation rate excludes many categories of students and types of success particularly applicable to community colleges. The purpose of...
