The Impact Of Nutrient Depletion On The Effect Of Hhq On Emiliania Huxleyi, Marley Gonsalves
The Impact Of Nutrient Depletion On The Effect Of Hhq On Emiliania Huxleyi, Marley Gonsalves
Honors Theses and Capstones
Emiliania huxleyi is a ecologically important, bloom-forming coccolithophore. HHQ is a bacteria compound that causes cell stasis in E. huxleyi that can lead to bloom termination. This study analyzed the role that nutrient depletion plays in this relationship. Results show that nitrogen depletion protects cells from the effects of HHQ, affecting bloom dynamics.
Screening Ocean Samples From Georgia For The Presence Of Msx And Dermo Using Pcr And Qpcr Methods, Olivia Michelle Williams
Screening Ocean Samples From Georgia For The Presence Of Msx And Dermo Using Pcr And Qpcr Methods, Olivia Michelle Williams
Honors Theses and Capstones
This Senior Thesis project aimed to be able to screen samples that came in from a PhD student in Georgia for the presence of two oyster diseases, MSX and Dermo. This study was done using PCR followed by visualizing on E-gels for initial presence of disease. These were then followed by qPCR and visualization on Criterion gels. These Criterion gels were able to be analyzed in order to calculate the pg/uL of MSX and Dermo in the original ocean samples. Since the samples were sent in over the course of February-August ‘21 the presence over time was also able to …

Isolation And Identification Of Bacterial Endosymbionts In The Brooding Brittle Star Amphipholis Squamata, Abbey Rose Tedford
Honors Theses and Capstones
Symbiotic associations with subcuticular bacteria (SCB) have been identified and studied in numerous echinoderms, including the SCB of the brooding brittle star, Amphipholis squamata. These SCB, however, have not been studied using current next generation sequencing technologies. Previous studies on the SCB of A. squamata placed these bacteria in the genus Vibrio (γ-Proteobacteria), but subsequent studies suggested that the SCB are primarily composed of α-Proteobacteria. The present study examines the taxonomic composition of SCB associated with A. squamata from the Northwest Atlantic. DNA was extracted using a CTAB protocol and 16S rRNA sequences were amplified …
