The prehispanic Moche culture, which flourished on the North Coast of Peru in the first millennium AD, has been the focus of archaeological investigation for decades. However, questions still linger regarding the nature of Moche political structure and warfare. The current study seeks to add to the information researchers can turn to when theorizing about the Moche by providing a more thorough examination of the variation in and distribution of violent behavior, including armed combat and human ...

This work addresses a focal question in ecological strategy theory, investigating the importance of carnivory to plant nutrient economy under differing conditions of substrate nutrient availability. Cost/benefit models predict that allocation to carnivory will increase as substrate nutrients decrease. I investigated allocation patterns of Sarracenia purpurea and relative contributions of nitrogen sources to the plant's nutrient budget, in two Gulf of Mexico coastal wet pine savannas differing in...

This study was designed to determine the relationship between Wuchereria bancrofti infection status, levels of circulating microfilarial, parasite antigenemia and antifilarial antibody responses. The effects of transmission season and concurrent helminth infections on filarial infection and antifilarial antibody responsiveness were also examined. The study was conducted in a population of 328 life-long residents aged $\geq$1 yr, in Muhaka, Kwale District, south coastal Kenya, an area endemic for...

The dissertation is comprised of three manuscripts presenting rare earth element (REE) and neodymium (Nd) isotopic analyses for the groundwaters, surface waters, sediments, and bedrocks of two estuaries along the eastern coast of the United States: Indian River Lagoon, Florida, and Pettaquamscutt Estuary, Rhode Island. This research was performed to understand the behavior of REEs in subterranean estuaries, the REE SGD fluxes, and the Nd isotopic composition of SGD. The selection of these sites ...

It is well recognized that rivers are the primary pathway that delivers sediment to the ocean. However, the fate of these sediments is poorly understood, and is complicated by relative sea level rise and meteorological forcings. One coastal system to examine these issues is the Atchafalaya River-Chenier Plain (ARCP) of southwest Louisiana, which relies on Mississippi River sediment supply and is vulnerable to coastal erosion and land loss. Despite regional coastal degradation, some land gain and...

An escalating environmental phenomenon is transpiring across global shorelines. Sea level rise and other factors effecting coastal geomorphology have not only resulted in significant land loss but loss of historical communities. Coastal Terrebonne Parish, located in southeastern Louisiana, experiences a complexity of detrimental factors. Communities with similar stories of diaspora and social marginalization have settled the region. For centuries, they have largely maintained their distinctive c...

The dissertation reports a series of hydrological studies that relates to seawater intrusion in a karst aquifer. In the Woodville Karst Plan (WKP), karst conduit system is well developed and directly open to the Gulf of Mexico that allows seawater intrudes into the aquifer. The Spring Creek Springs Complex and Wakulla Spring, located in a marine estuary and 11 miles inland, respectively, are the two major groundwater discharge spots and connected through subsu...

In the uppermost millimeters of shallow submerged coastal sediments, photosynthesis by microalgae and cyanobacteria during daylight hours can cause oxygen supersaturation of sediment porewater, leading to bubble formation. In shallow water depths, the seabed is affected by the pressure maximum beneath the wave crest and pressure minimum beneath the wave trough. While the photosynthetically-generated gas bubbles persist within the surface layer highly permeable sand sedime...

Submarine groundwater discharge (SGD) assessments conducted both in the laboratory and at a field site in the northeastern Gulf of Mexico, using a continuous-heat type automated seepage meter (seepmeter) have shown that the device has the potential of providing long-term, high-resolution measurements of SGD. The improvements on the device using a simple inexpensive laboratory set up, have shown that: (1) connecting an extension cable to the seepmeter has a negligible effect on its measuring capa...

Coastal ecosystems are among the most productive in the world, and they serve as an invaluable resource to society. Despite many decades of biogeochemical research in the coastal zone, carbon and nutrient budgets remain uncertain largely due to the inherent complexity and spatiotemporal variability observed in coastal ecosystems. This dissertation addresses the rates, pathways, and microorganisms responsible for organic-matter mineralization and nutrient release in the sediments of coastal marin...

The purpose of this study was to explore the knowledge level of nutrition and physical activity among rural school-age children in a north Florida coastal community. There is evidence to support a correlation between nutrition and physical activity with obesity in children. The children who participated were living in a rural, coastal community in north Florida. They were school-age ranging from 3rd grade to 7th grade. This was a convenience sample from an after-school program (The Boy's and Gir...

The purpose and focus of this research was on studying the hazard to Florida's coastal bridges from storm surge induced wave forces inflicted on the bridges during hurricanes. It has been observed in recent years that bridges located in the coastal environment are vulnerable to deck unseating during the applied loading of storm surge wave forces. The goal of the research is to use modern and up-to-date analysis methods to address the risk and vulnerability of coastal bridges to being damaged fro...

Paleotempestology is the study of long-term regional storm history from geological proxy evidence. This relatively recent field of geology offers a glimpse at tropical cyclone activity extending back into geologic time. Historic documentation of tropical storms extends only about 150 years into the past and is not necessarily representative of the geologic record. The historic record can be used to assess decadal and multi-decadal cycles and provide some insight into the near future climate. In ...

During an El Niño anomalous westerly winds in the central equatorial Pacific push the equatorial water eastward, raising the sea level in the eastern equatorial Pacific and lowering it in the western equatorial Pacific. In the western equatorial Pacific, this sea level signal leaks through gaps in the western equatorial Pacific boundary, lowering sea level all around the western and southern coasts of Australia. Opposite anomalies occur during La Niña when the equatorial winds are easterly. Assu...

Shallow water availability coupled with anthropogenic degradation of seagrass beds limits wading bird food resources in dynamic coastal ecosystems. Identifying prey species critical to wading bird reproductive success and the environmental drivers of key prey species abundance is important for understanding how environmental stressors influence prey and change the quality of foraging patches. Little Blue Herons (Egretta caerulea) are reportedly generalists eating insects, crustaceans, and fish; ...

As top-level piscivores, Bald Eagles are a compelling subject for the study of territory dynamics and are highly representative of the distinctive suite of avian species that occupy Florida Bay. Despite successful recovery of Bald Eagles (Haliaeetus leuocephalus) throughout the species range, the population breeding within Florida Bay has not mirrored this trend. Beginning in the late 1980s, Florida Bay has suffered in its capacity to support species diversity and abundance as a result of e...

Shrimp mariculture expansion in developing countries has been criticized for its ecological destruction and the resulting social conflicts. In Ecuador, shrimp pond development particularly affects rural, coastal communities. This study addresses the environmental and social effects of shrimp farming in two Ecuadorian villages, Muisne and Bunche. Interview and survey responses indicate that locals have an overall negative view of the industry. In some instances, such as increased class marginaliz...

New data on human skeletal remains from Site 35 in Salango, Ecuador is combined with existing data presented by Jastremski (2006) to compile a more comprehensive report about the health conditions of the people. Site 35, which is associated with the Manteño culture that flourished in the Integration period from A.D. 500 – 1532, has been determined to comprise a singular population that is represented by a minimum of 27 individuals. In addition to more comprehensive conclusions about Site 35...

The purpose of this dissertation was to study to phylogenetic relationships among a group of uncharacterized bacterial strains isolated from topsoil and two deep aquifer sediments at a study site in South Carolina. Of particular interest were: (i) how these uncharacterized strains are related to established bacterial taxa, (ii) whether strains with similar physiological traits are closely related phylogenetically, and (iii) how closely topsoil and deep-aquifer bacteria at the same study site are...

Thesis advisor: Noah P. Snyder / Substrate size and mobility are important to Atlantic salmon (Salmo salar) spawning and rearing success. Channel geometry is a control on bedload mobility in streams. It is believed that channel morphology in many Maine rivers has been altered by land use practices, creating wider and shallower channels, and lowering stream competence. If correct, these changes may be partially responsible for the limited number of returning salmon currently observed in Maine ...

The subsidized island biogeography hypothesis proposes that nutrient subsidies, those translocated from one ecosystem to another, can indirectly influence species richness on islands by directly increasing terrestrial productivity. However, the lack of a formal statistical model makes it difficult to assess the strength of the hypothesis. I created a formal subsidized island biogeography model to determine how nutrient subsidies, in addition to area and distance from mainland, influence tree spe...

This dissertation explores how the tea-growing districts of China and colonial India were integrated into the global division of labor over a formative century of boom-bust expansion. I explore this history of competition by highlighting two dimensions of economic and intellectual change: the intensification of agrarian labor and the synchronous emergence of new paradigms of economic thought. As tea exports from China and India soared and competition grew fiercer, planters, factory overseers, pe...
