Analysis Of Temperature And Salinity Effects On Growth And Mortality Of Oysters (Crassostrea Virginica) In Louisiana, Troy Sehlinger

University of New Orleans Theses and Dissertations

Salinity (S) and temperature (T) control every facet of the eastern oyster (Crassostrea virginica) life cycle, principally reproduction, development, growth, and mortality. Previous studies conducted in in the Breton Sound (BR) and Barataria (BA) estuaries have reported differences in growth and mortality rates between the basins. In the present study, environmental conditions were synchronized to compare growth and mortality rates between basins at similar combinations of T and S. Results indicate that when T and S are the same (synchronized), seasonal oyster growth and mortality rates differ between BR and BA. Seasonal analyses revealed that as salinities increased …

Using Digital Mapping Techniques To Rapidly Document Vulnerable Historical Landscapes In Coastal Louisiana: Holt Cemetery Case Study, Alahna Moore

University of New Orleans Theses and Dissertations

This thesis outlines a technique for rapid documentation of historic sites in volatile cultural landscapes. Using Holt Cemetery as an exemplary case study, a workflow was developed incorporating RTK terrain survey, UAS aerial imagery, photogrammetry, GIS, and smartphone data collection in order to create a multifaceted database of the material and spatial conditions, as well as the patterns of use, that exist at the cemetery.

The purpose of this research is to create a framework for improving the speed of data creation and increasing the accessibility of information regarding threatened cultural resources. It is intended that these processes can be …

Both Sides Of The Barbed Wire: Lives Of German Prisoners Of War And African Americans In Camp Claiborne, Louisiana, 1944-1946, Claire Delucca

University of New Orleans Theses and Dissertations

Located outside of Alexandria, Louisiana, Camp Claiborne was temporarily home to more than 500,000 U.S. servicemen and women during its short existence. Thousands of German prisoners of war also were held for more than two years in a section of the camp. Racial problems stemming from the policies of Jim Crow South and the blatant inequality eventually led to an African American mutiny within the camp. The events from 1944 to 1946 at Camp Claiborne provide insight into the mindsets of white Southerners and the generation of African Americans who would influence the major civil rights victories in the following …
