Effects of St. Lucie Estuarine Discharge Water and Thermal Stress on the Coral Montastraea cavernosa

Effects of St. Lucie Estuarine Discharge Water and Thermal Stress on the Coral Montastraea cavernosa.

Abstract/Description
Coral reef declines, particularly in coastal zones, have been linked to thermal stress and anthropogenic impacts on water quality. St. Lucie Reef near Stuart, Florida receives increased estuarine efflux as a result of watershed changes and management policies that have substantially altered historic, natural flows. This research used ambient and elevated temperatures (25°C and 30°C, respectively), and offshore versus St. Lucie Estuarine discharge water to investigate the individual and...
Show moreCoral reef declines, particularly in coastal zones, have been linked to thermal stress and anthropogenic impacts on water quality. St. Lucie Reef near Stuart, Florida receives increased estuarine efflux as a result of watershed changes and management policies that have substantially altered historic, natural flows. This research used ambient and elevated temperatures (25°C and 30°C, respectively), and offshore versus St. Lucie Estuarine discharge water to investigate the individual and interactive effects of thermal and water quality stress on Montastraea cavernosa, a dominant scleractinian coral species at St. Lucie Reef. These goals were accomplished using ex-situ, factorial, experimental design that was supplemented with existing in-situ monitoring on St. Lucie Reef. Zooxanthellae density and chlorophyll content were evaluated to determine effects on the corals and their symbionts. Zooxanthellae populations were significantly affected by thermal stress. Significant interactions between temperature and water treatment were observed, suggesting that the impacts of discharge water may be supplanted when corals are exposed to thermal stress. In a supplement to the experiment, M. cavernosa colonies transplanted from Palm Beach to St. Lucie Reef demonstrated resilience despite exposure to more variable environmental conditions. Collaborative partnerships with multiple state agencies and local government offices facilitated data sharing to inform decision making for South Florida’s resource management strategies. Creating effective resource management is crucial for the conservation of coastal ecosystems impacted by land-based sources of pollution both locally and globally.

An Assessment of Fecal Pollution in the St. Lucie Estuary and Indian River Lagoon
Title
An Assessment of Fecal Pollution in the St. Lucie Estuary and Indian River Lagoon.
Creator
Perricone, Carlie S., McCarthy, Peter J., Florida Atlantic University, Charles E. Schmidt College of Science, Department of Biological Sciences
Abstract/Description
Contamination of recreational waters with fecal waste, indicated by the presence of enterococci, can have consequences for human and ecosystem health. The difficulty in determining the extent and origin of fecal pollution in dynamic estuarine systems is compounded by contributions from sources including septic tanks and agricultural runoff. This study investigated fecal pollution at five sites with variable hydrological conditions in the St. Lucie Estuary and Indian River Lagoon. The...
Show moreContamination of recreational waters with fecal waste, indicated by the presence of enterococci, can have consequences for human and ecosystem health. The difficulty in determining the extent and origin of fecal pollution in dynamic estuarine systems is compounded by contributions from sources including septic tanks and agricultural runoff. This study investigated fecal pollution at five sites with variable hydrological conditions in the St. Lucie Estuary and Indian River Lagoon. The distribution and occurrence of enterococci was assessed using traditional cultivation. A human-associated microbial source tracking assay was validated and applied in these estuaries using qPCR. Results demonstrated a correlation between enterococci concentrations, rainfall, and salinity. The human-associated assay was sensitive and specific in the lab; however, human fecal pollution was not detected in the field even though samples contained high levels of enterococci. This study highlights the importance of expanding the range of water quality assessment.

The Ascidian Styela plicata As a Potential Bioremediator of the Brown Tide Pelagophytes Aureoumbra lagunensis and Aureococcus anophagefferens
Title
The Ascidian Styela plicata As a Potential Bioremediator of the Brown Tide Pelagophytes Aureoumbra lagunensis and Aureococcus anophagefferens.
Creator
Klarmann, Phyllis A., Hartmann, James X., Florida Atlantic University, Charles E. Schmidt College of Science, Department of Biological Sciences
Abstract/Description
A brown tide bloom of the pelagophyte Aureoumbra lagunensis caused significant impacts to north Indian River Lagoon (IRL) in 2012-2013, including seagrass die-offs, fish kills, and reduced growth and grazing of ecologically important bivalves. There is potential for another pelagophyte, Aureococcus anophagefferens, to expand into this system. Filtration rates (FR) of the pleated tunicate Styela plicata exposed to Aureoumbra lagunensis and Aureococcus anophagefferens were measured against...
Show moreA brown tide bloom of the pelagophyte Aureoumbra lagunensis caused significant impacts to north Indian River Lagoon (IRL) in 2012-2013, including seagrass die-offs, fish kills, and reduced growth and grazing of ecologically important bivalves. There is potential for another pelagophyte, Aureococcus anophagefferens, to expand into this system. Filtration rates (FR) of the pleated tunicate Styela plicata exposed to Aureoumbra lagunensis and Aureococcus anophagefferens were measured against exposure to a control alga (Tisochrysis lutea) in order to determine its potential use as a bioremediator against these harmful algal blooms (HABs). In addition, whether S. plicata might serve as a vector of HABs was studied by culturing fecal deposits. Short-term exposure to HABs significantly reduced FR, whereas long-term exposure indicates comparable cell removal compared to the control. Vector potential of S. plicata was inconclusive. Results warrant further research to determine whether S. plicata can acclimate or respond to HAB conditions over time.
