Population Dynamics And Community Composition Of Ammonia Oxidizers In Salt Marshes After The Deepwater Horizon Oil Spill, Anne E. Bernhard, Roberta Sheffer, Anne E. Giblin, John M. Marton, Brian J. Roberts Jun 2016

Population Dynamics And Community Composition Of Ammonia Oxidizers In Salt Marshes After The Deepwater Horizon Oil Spill, Anne E. Bernhard, Roberta Sheffer, Anne E. Giblin, John M. Marton, Brian J. Roberts

Biology Faculty Publications

The recent oil spill in the Gulf of Mexico had significant effects on microbial communities in the Gulf, but impacts on nitrifying communities in adjacent salt marshes have not been investigated. We studied persistent effects of oil on ammonia-oxidizing archaeal (AOA) and bacterial (AOB) communities and their relationship to nitrification rates and soil properties in Louisiana marshes impacted by the Deepwater Horizon oil spill. Soils were collected at oiled and unoiled sites from Louisiana coastal marshes in July 2012, 2 years after the spill, and analyzed for community differences based on ammonia monooxygenase genes (amoA). Terminal Restriction Fragment …

Response Of Bird Populations To Long-Term Changes In Local Vegetation And Regional Forest Cover, Mary Buchanan, Robert A. Askins, Chad C. Jones Jan 2016

Response Of Bird Populations To Long-Term Changes In Local Vegetation And Regional Forest Cover, Mary Buchanan, Robert A. Askins, Chad C. Jones

Biology Faculty Publications

We analyzed data from a woodland site for a 59-year period to determine whether changes in bird populations are related to changes in the diversity and relative abundance of woody plant species even when vegetation structure, degree of forest fragmentation in the surrounding landscape, and regional changes in bird populations are taken into account. Principal component analyses generated vegetation factors encompassing variables such as total basal area, shrub density, basal area of common tree species, and measures of tree and shrub species diversity. We also calculated a forest edge/ forest area index based on GIS analysis of the landscape within …


Elasmobranchii: A Survey Study On The Impact Of Our Everyday Choices In Marine Environments, Zoe Davis Jan 2016

Elasmobranchii: A Survey Study On The Impact Of Our Everyday Choices In Marine Environments, Zoe Davis

Biology Honors Papers

Oceans cover two‐thirds of our total planet surface area, ignoring the significance of depth, and even so, humans affect and change the ocean daily. This change is not often intentional or conscious, but rather is usually indirect. The hypothesis that humans do not consider how their actions affect the ocean unless they are educated on the subject matter and/or live within 25 miles of a coastline was examined through two survey studies. The purpose was to observe actions that affected the ocean and see if there were any trends with participants knowing which actions were positive for the ocean or …
