Describing The Effect Of Thin Layer Sediment Placement On Coastal Microbial Communities Using Foraminifera Diversity, Elizabeth B. Billings
Describing The Effect Of Thin Layer Sediment Placement On Coastal Microbial Communities Using Foraminifera Diversity, Elizabeth B. Billings
Senior Honors Projects
Salt marshes are rich ecosystems that play an important role in aquatic food systems and prevent erosion while also providing essential habitats for wildlife. Climate change has resulted in rising sea levels and erosion of these coastal wetlands. Thin Layer Sediment Placement (TLP) is a restoration effort being implemented to mitigate the effects of climate change on coastal ecosystems. The TLP process raises elevation of the marsh and provides substrates for vegetative growth by spraying dredged sediment over existing marsh. The impacts of TLP on microbial populations is not widely understood, therefore metrics are required to study the effects of …
Surveying Apicomplexan Diversity And Dynamics In Narragansett Bay, Evelyn Spencer
Surveying Apicomplexan Diversity And Dynamics In Narragansett Bay, Evelyn Spencer
Senior Honors Projects
Parasites play an important role in marine ecosystems and their diversity is generally understudied. Apicomplexans, a group of parasitic protists in the phylum Alveolata, infect a wide variety of animal hosts and are abundant in ecosystems spanning from Polar Regions to Neotropical rainforests. Previous data generated from marine sediments in Antarctica, Naples Bay, and off the coast of Oslo, exhibit high diversity and numbers of apicomplexans. Abundance and diversity of these protists are unknown for Narragansett Bay, despite the fact that they infect many commercially important species. The aim of my study was to obtain abundance data and understand genetic …
Brown Algal Diversity In Bermuda Revealed Using Molecular Tools, Alyssa L. Rogers
Brown Algal Diversity In Bermuda Revealed Using Molecular Tools, Alyssa L. Rogers
Senior Honors Projects
For nearly 60 years there has been very little investigation of the marine algal flora in Bermuda, which is an ideal location for a biodiversity assessment due to its size and location. Residing approximately 1000km off the coast of North Carolina, Bermuda is influenced by the cool water from the north during winter and by the warm water eddies that spin off the Gulf Stream for the much of the other seasons. The Bermuda Seaweed Project aims to extensively survey the marine algal flora in Bermuda and generate morphological and molecular data for all three major groups of macroalgae present. …

Hexachlorocyclohexanes (HCHs) are a family of chlorinated organic compounds that were previously used as agricultural insecticides. HCHs are recognized as persistent organic pollutants due to their toxicity, recalcitrant properties, and tendency to bioaccumulate in food webs. Although HCH was first synthesized in 1825, its use was not widespread until the discovery of the insecticidal activity of the γ-HCH isomer in 1942. γ-HCH and its toxic waste isomers α-HCH and β-HCH were banned from production and use by the United Nations in 2009, yet these chemicals still present environmental problems due to their persistence in soils and surface waters. HCHs continue …
