Effects of St. Lucie Estuarine Discharge Water and Thermal Stress on the Coral Montastraea cavernosaUnknown Date (has links)
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 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. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2017. / FAU Electronic Theses and Dissertations Collection

Heavy metals in biota from temperate Australian estuariesClaus, Sonia Carmel, University of Western Sydney, College of Science, Technology and Environment, School of Science, Food and Horticulture January 2003 (has links)
The detection of anthropogenic impacts in our estuaries has become a critical social, political and scientific concern in recent years. Work has focussed on the effects of these impacts on the spatial and temporal patterns of biotic assemblages and searched for bioindicators and biomarkers of pollutants that may act as early warning signs. The estuaries in temperate Southeastern Australia have a diversity of biotic assemblages living in the soft sediment. One of the most abundant macroinvertebrates is the little studies mussel, Xenostrobus securi that is found living with an assemblage of benthic biota including amphipods, crabs, isopods and tanaids, bivalves and gastropods. Two commercial fish species bream and mullet also inhabit these estuaries. Numerous stormwater drains can be found entering the estuaries through the mangrove forests lining the shores. Along with inputs of freshwater, stormwater drains are thought to be responsible for the entry of heavy metals into estuaries. These heavy metals have the potential to alter the patterns of biotic assemblages and bioaccumulate in the tissues of miacroinvertebrates, mussels and fish living within temperate estuaries. Over the time of this study the concentrations of heavy metals in the sediment tissues and shell of X.Securis varies spatially and temporally. Although this study adds substantially to current knowledge there is still more that is needed to establish X. Securis as a bioindicator. Questions remain about uptake, depuration and response to environmental gradients of heavy metals in X. Securis. Before X Securis can be used routinely in monitoring heavy metal contamination these questions need to be further investigated / Doctor of Philosophy (PhD)
