- Assessment of multiple paternity for the queen conch, Strombus gigas.
- Creator
- Harris, Chris., Harriet L. Wilkes Honors College
- Abstract/Description
-
The commercially important queen conch, Strombus gigas, has been observed copulating with multiple partners and laying multiple egg masses during a reproductive season (Randall, 1964). While multiple paternity has been confirmed using microsatellite based genetic analysis for a variety of other gastropods, this technique has not been employed for S. gigas. Determining whether or not this species is capable of multiple paternity is important to understanding and maintaining genetic diversity...
Show moreThe commercially important queen conch, Strombus gigas, has been observed copulating with multiple partners and laying multiple egg masses during a reproductive season (Randall, 1964). While multiple paternity has been confirmed using microsatellite based genetic analysis for a variety of other gastropods, this technique has not been employed for S. gigas. Determining whether or not this species is capable of multiple paternity is important to understanding and maintaining genetic diversity of natural and captive populations. While an assessment of multiple paternity is the ultimate goal of this study, for my thesis, I have completed preliminary work which includes perfecting methods of tissue collection, DNA extraction, and DNA amplification with six non-labeled polymorphic microsatellite molecular markers, using cultured Strombus gigas animals. In addition, I collected tissue and extracted DNA from three wild S. gigas adult females and their egg masses from Pelican Shoal in the Florida Keys.

- Ecosystem health and environmental influences on innate immune function in the loggerhead (Caretta caretta) and green (Chelonia mydas) sea turtle.
- Creator
- Sposato, Patricia L., Milton, Sarah L., Florida Atlantic University, Charles E. Schmidt College of Science, Department of Biological Sciences
- Abstract/Description
-
Loggerhead (Caretta caretta) and green (Chelonia mydas) turtles recruit to nearshore environments as juveniles. These often degraded habitats are associated with emerging diseases such as green turtle fibropapillomatosis (GTFP), however there are few studies on immune function in sea turtles. The objective of this research was to quantify phagocytosis of the innate immune system by flow cytometry and compare levels between animals from a degraded habitat (the Indian River Lagoon, FL) to a...
Show moreLoggerhead (Caretta caretta) and green (Chelonia mydas) turtles recruit to nearshore environments as juveniles. These often degraded habitats are associated with emerging diseases such as green turtle fibropapillomatosis (GTFP), however there are few studies on immune function in sea turtles. The objective of this research was to quantify phagocytosis of the innate immune system by flow cytometry and compare levels between animals from a degraded habitat (the Indian River Lagoon, FL) to a more pristine environment (the Trident Basin, Port Canaveral, FL), and across a range of temperatures. While in vitro temperatures did not alter rates of phagocytosis, it was higher in samples obtained in the summer than winter. Rates of phagocytosis in sea turtles with GTFP and from degraded environments with increased prevalence of GTFP were low compared to animals from the more pristine environment, suggesting that the environment can alter innate immunological function and thus contribute to the development of disease.

- Toxicity and availability of copper and zinc to queen conch: implications for larval recruitment in the Florida Keys.
- Creator
- Garr, Amber L., Charles E. Schmidt College of Science, Department of Biological Sciences
- Abstract/Description
-
The presence of heavy metals and other pollutants is detrimental to marine ecosystems. The queen conch, once an important fisheries species in the Florida Keys, has not sufficiently recovered after a 25-year fishery closure. Research has shown high levels of copper and zinc in the gonads and digestive glands of adult conch found in the nearshore waters. Four sites relevant to queen conch larval recruitment were tested in 2010 for the presence of copper and zinc in the water, phytoplankton,...
Show moreThe presence of heavy metals and other pollutants is detrimental to marine ecosystems. The queen conch, once an important fisheries species in the Florida Keys, has not sufficiently recovered after a 25-year fishery closure. Research has shown high levels of copper and zinc in the gonads and digestive glands of adult conch found in the nearshore waters. Four sites relevant to queen conch larval recruitment were tested in 2010 for the presence of copper and zinc in the water, phytoplankton, sediment, and seagrass epiphytes over seven months. Both metals were detected in all sample types and no seasonal or geographical differences were detected. Surface water concentrations from the field were used to conduct acute and chronic toxicity tests on various ages of queen conch larvae and their phytoplankton food source. When zinc concentrations (0-40 (So(Bg/L) similar to those measured in situ were used, there was no significant impact on conch larval survival although some velar lobe de velopment was impaired. However, field concentrations of copper (0-15 (So(Bg/L), which often surpassed water quality standards, negatively impacted growth, survival, and development of the larvae. Chronic exposure to copper, through the water and food, disrupted the metamorphic success of competent larvae and decreased post-metamorphosis survival. Exposure to copper at later life stages increased mortality, suggesting that heavy metals have a negative effect on larval recruitment in localized areas of the Florida Keys. Structural equation modeling revealed that copper and zinc are moving through the systems differently and are best represented by two different models.

- Coral-Algal Symbioses in Mesophotic Montastraea cavernosa in the Gulf of Mexico.
- Creator
- Polinski, Jennifer, Voss, Joshua, Florida Atlantic University, Charles E. Schmidt College of Science, Department of Biological Sciences
- Abstract/Description
-
Mesophotic reefs represent biodiverse ecosystems that may act as a refuge for depth-generalist coral species threatened in shallow habitats. Despite the importance of coral-algal symbioses, few studies focus on mesophotic zooxanthellae assemblages and their influence on connectivity. This study compared zooxanthellae in Montastraea cavernosa at shallow and mesophotic depths at Flower Garden Banks National Marine Sanctuary and McGrail Bank. Mesophotic corals contained more zooxanthellae and...
Show moreMesophotic reefs represent biodiverse ecosystems that may act as a refuge for depth-generalist coral species threatened in shallow habitats. Despite the importance of coral-algal symbioses, few studies focus on mesophotic zooxanthellae assemblages and their influence on connectivity. This study compared zooxanthellae in Montastraea cavernosa at shallow and mesophotic depths at Flower Garden Banks National Marine Sanctuary and McGrail Bank. Mesophotic corals contained more zooxanthellae and more chlorophyll a and c2 per unit area coral. Increased zooxanthellae within mesophotic corals may represent an adaptive strategy to optimize light capture in low-light environments. Genetic profiles for zooxanthellae assemblages from shallow and mesophotic corals showed similar diversity across banks and between depths. The dominant sequence making up assemblages was identified as Symbiodinium type C1. Similar assemblage diversity suggests that zooxanthellae assemblages will not limit connectivity potential between shallow and mesophotic corals at these reefs.
