Legacy mining facilities pose significant risks to aquatic resources. From March 30th to April 9th, 2021, 814 million liters of phosphate mining wastewater and marine dredge water from the Piney Point facility were released into lower Tampa Bay (Florida, USA). This resulted in an estimated addition of 186 metric tons of total nitrogen, exceeding typical annual external nitrogen load estimates to lower Tampa Bay in a matter of days. An initial phytoplankton bloom (non-harmful diatoms) was first observed in April. Filamentous cyanobacteria blooms (Dapis spp.) peaked in June, followed by a bloom of the red tide organism Karenia brevis …


Shallow-Water Coral Communities Support The Separation Of Marine Ecoregions On The West-Central Florida Gulf Coast, Brian K. Walker, Shelby Eagan, Cory Ames, Sandra Brooke, Sean Keenan, Rene Baumstark Jun 2020

Shallow-Water Coral Communities Support The Separation Of Marine Ecoregions On The West-Central Florida Gulf Coast, Brian K. Walker, Shelby Eagan, Cory Ames, Sandra Brooke, Sean Keenan, Rene Baumstark

Florida’s west coast is a 170,000 km2 bedrock shelf (west Florida shelf, WFS) comprised of north-south discontinuous carbonate outcroppings extending more than 200 km from the intertidal zone to a depth of 200 m. These outcrops support diverse benthic communities, which contribute to a multi-billion dollar recreational and commercial fishing industry, yet only about 5% of their extent has been studied in detail. Benthic communities shift over a 6.5° geographic range, but the locations of these shifts are not well-defined. Previous studies have suggested a break in biogeographic regions at Tampa Bay, south at Cape Romano, and north at …


Shallow- Water Hardbottom Communities Support The Separation Of Biogeographic Provinces On The West- Central Florida Gulf Coast, Shelby Eagan Jul 2019

Shallow- Water Hardbottom Communities Support The Separation Of Biogeographic Provinces On The West- Central Florida Gulf Coast, Shelby Eagan

HCNSO Student Theses and Dissertations

Several studies have found separation of biogeographic provinces on the West Florida Shelf (WFS), but the location of this separation differs depending on different organisms with faunal boundaries proposed at Apalachicola, Cedar Key, Anclote Key. Tampa Bay, Charlotte Harbor, Cape Romano, or Cape Sable. Biogeographic boundaries can be gradual over a given space and are often species-specific. Analyses of marine benthic mapping and community characterization of Florida’s West-central coast shallow water (depth) hardbottom habitats indicate a major shift in the benthos across Tampa Bay. Quantitative benthic surveys of 29 sites yielded a total of 4,079 individuals of nine stony coral …


Sex And The Seas: Gene Transfer Agents, Elizabeth Young Jan 2011

Sex And The Seas: Gene Transfer Agents, Elizabeth Young

USF Tampa Graduate Theses and Dissertations

Gene Transfer Agents (GTAs) are phage-like pthesiss that are produced by many alpha proteobacteria in late stationary growth phase and are capable of transferring chromosomal genes (termed "constitutive transduction"). Examination of alpha proteobacterial genomic sequences indicated widespread occurrence of GTA-like elements. The goal of this study was to investigate gene transfer potential of GTAs of marine alpha proteobacteria in culture as well as in natural marine environments. Another goal was to determine the potential of bacterial symbionts from zooxanthellae and coral to genetically transfer beneficial properties between symbionts. Ruegeria mobilis (ID 45A6) was isolated from cultures of the coral endosymbiotic …
