Abstract/Description
Coastal development shifts natural hydrology through water redirection, increased impervious surfaces, and increased connectivity to the coastal ocean through inlets. In Southeast Florida, watershed alterations can cause flash-freshening in nearshore coastal habitats, threatening coral reef ecosystems. This study assessed the hyposalinity tolerance threshold of two prominent scleractinian corals in Southeast Florida. In a series of experiments, we determined that Montastraea cavernosa corals...
Show moreCoastal development shifts natural hydrology through water redirection, increased impervious surfaces, and increased connectivity to the coastal ocean through inlets. In Southeast Florida, watershed alterations can cause flash-freshening in nearshore coastal habitats, threatening coral reef ecosystems. This study assessed the hyposalinity tolerance threshold of two prominent scleractinian corals in Southeast Florida. In a series of experiments, we determined that Montastraea cavernosa corals have an LC50 of 19 PSU but can survive for at least 21 days at an intermediately stressful salinity of 25 PSU. Porites astreoides corals demonstrated an LC50 of 19 PSU, but experienced mortality when exposed to 25 PSU for 17–18 days. Prior to mortality, corals displayed decreased polyp activity, altered coloration, and decreased tissue integrity. These data suggest that lower-volume, longer-duration releases of freshwater from reservoirs may preserve coral health in Southeast Florida.

Abstract/Description
Short-term increases in temperatures above 31°C have been shown to influence the structure and diversity of coral reefs through coral bleaching episodes, but quantitative information on how these thermal events affect macroalgae on coral reef communities has rarely been described.

Show moreShort-term increases in temperatures above 31°C have been shown to influence the structure and diversity of coral reefs through coral bleaching episodes, but quantitative information on how these thermal events affect macroalgae on coral reef communities has rarely been described. Using laboratory mesocosm experiments, I examined six species of commonly occurring macroalgae from two functional form groups on the Florida Keys reef tract to determine their temperature thresholds, quantified by the point at which photosynthesis, quantum yield (Fv/Fm), and mortality rates were significantly affected. Red crustose coralline sp., classified in the calcareous group, showed no significant changes in Fv/Fm, and experienced no mortality at elevated temperatures of 34°C. However, Halimeda incrassata, another calcareous species showed significant changes in photosynthesis at thermal treatments of 32°C, and experienced 75% mortality at 34°C. Sargassum fluitans, a branching fleshy macroalgae maintained photosynthetic rates up to 32°C, but at 34°C succumbed to 100% mortality. Laurencia chondroides, also a branching fleshy macroalgal form experienced 50% mortality at 34°C. My results, among the first high temperature experiments on dominant tropical macroalgae, indicate that macroalgae are more robust than corals (∼32°C) in their thermal tolerance, but have varying thresholds among species.

Abstract/Description
Coral bleaching involves the loss of symbiotic algae (zooxanthellae) from reef corals and other cnidarians during periods of environmental stress, particularly elevated temperature. In this study the thermal bleaching responses of the zoanthid Palythoa caribaeorum from three populations along the southeast coast of Florida were compared. Winter (2002--2003) and summer (2003) samples from three geographically separate sites were exposed to increased temperatures and the loss of zooxanthellae...
Show moreCoral bleaching involves the loss of symbiotic algae (zooxanthellae) from reef corals and other cnidarians during periods of environmental stress, particularly elevated temperature. In this study the thermal bleaching responses of the zoanthid Palythoa caribaeorum from three populations along the southeast coast of Florida were compared. Winter (2002--2003) and summer (2003) samples from three geographically separate sites were exposed to increased temperatures and the loss of zooxanthellae was measured. Zooxanthellae populations were sampled and identified using PCR-DGGE. The results showed that samples of P. caribaeorum from reefs that experience smaller annual thermal ranges released the most zooxanthellae. Seasonal comparisons revealed winter samples experienced a greater amount of zooxanthellae loss than summer samples. P. caribaeorum was found to harbor two genetic strains of zooxanthellae, C1 and D1a. Colonies either contained monotypic populations of these, or a combination of both.

Abstract/Description
Coral reefs on Florida’s Reef Tract (FRT) are susceptible to many anthropogenic influences including controlled freshwater discharges and agricultural runoff as well as high natural environmental variability from seasonal rainfall, runoff and upwelling. To better understand coral population structure and responses to sublethal stressors, populations of the scleractinian coral Montastraea cavernosa in the northern FRT were examined using a combination of genomic and transcriptomic techniques....
Show moreCoral reefs on Florida’s Reef Tract (FRT) are susceptible to many anthropogenic influences including controlled freshwater discharges and agricultural runoff as well as high natural environmental variability from seasonal rainfall, runoff and upwelling. To better understand coral population structure and responses to sublethal stressors, populations of the scleractinian coral Montastraea cavernosa in the northern FRT were examined using a combination of genomic and transcriptomic techniques. Microsatellite genetic markers identified high local retention among sites and a slight southward gene flow. An in-situ temporal gene expression analysis utilizing a tag-based sequencing transcriptomic approach was used to analyze baseline coral health at St. Lucie Reef (SLR), off Stuart, FL. Temporal variation had the greatest influence of differential gene expression among M. cavernosa at SLR. Results will be shared with local resource managers and coupled with a complementary ex-situ experimental trial.

Distribution and Diversity of Benthic Foraminifera Within the Nearshore Ridge Complex off Pompano Beach, Broward County, Florida.
Creator

Abstract/Description
Benthic foraminifera are exceptional organisms with distinctive features that allow for interpretation of both past and present environmental conditions. Some benthic foraminifera are widely distributed while some are restricted to specific environments due to their way of life. Foraminiferal assemblages south of Biscayne Bay and north of Cape Canaveral have previously been investigated; however, a gap exists in data covering a transitional zone along the Florida coast between the tropical...
Show moreBenthic foraminifera are exceptional organisms with distinctive features that allow for interpretation of both past and present environmental conditions. Some benthic foraminifera are widely distributed while some are restricted to specific environments due to their way of life. Foraminiferal assemblages south of Biscayne Bay and north of Cape Canaveral have previously been investigated; however, a gap exists in data covering a transitional zone along the Florida coast between the tropical waters of the western Atlantic and the cooler coastal waters along the North American coast. The purpose of this study was to collect baseline data on the benthic foraminifera of the small marine environment off of Pompano Beach that falls within this zone. This environment has a very particular relict reef system that includes a near-shore ridge complex, the unique foraminiferal assemblage of which has not been documented. Thirteen rubble samples were collected from this near shore ridge complex between October 2013 and April 2015 from depths of 2.5m – 9m. Abundances and diversity indices were calculated, and multivariate analysis and SHEBI analysis carried out to summarize baseline data for the area. Substrate types and seasonal collections were compared with foraminiferal abundances to determine if benthic foraminifera diversity varied between the four substrate types found on the near-shore ridge and between wet and dry seasons in Florida. Results revealed a variation in abundances for both substrates and seasons with the dominant genera being Quinqueloculina, Laevipeneroplis, and Archaias. Multivariate analysis displayed dissimilarities between substrates colonized by corals and those that were uncolonized. Comparison of studies from surrounding areas revealed fewer, however similar, species and different dominant genera. Overall, this area has proven to be a different environment compared to surrounding coastal areas and merits further investigation.
