Application Of Biomarkers And Compound Specific Stable Isotopes For The Assessment Of Hydrology As A Driver Of Organic Matter Dynamics In The Everglades Ecosystem, Ding He
FIU Electronic Theses and Dissertations
The Everglades is a sub-tropical coastal wetland characterized among others by its hydrological features and deposits of peat. Formation and preservation of organic matter in soils and sediments in this wetland ecosystem is critical for its sustainability and hydrological processes are important divers in the origin, transport and fate of organic matter. With this in mind, organic matter dynamics in the greater Florida Everglades was studied though various organic geochemistry techniques, especially biomarkers, bulk and compound specific δ13C and δD isotope analysis. The main objectives were focused on how different hydrological regimes in this ecosystem control organic matter …
A Review Of The Effects Of Altered Hydrology And Salinity On Vertebrate Fauna And Their Habitats In Northeastern Florida Bay, Jerome J. Lorenz
A Review Of The Effects Of Altered Hydrology And Salinity On Vertebrate Fauna And Their Habitats In Northeastern Florida Bay, Jerome J. Lorenz
FCE LTER Journal Articles
Estuarine productivity is highly dependent on the freshwater sources of the estuary. In Florida Bay, Taylor Slough was historically the main source of fresh water. Beginning in about 1960, and culminating with the completion of the South Dade Conveyance System in 1984, water management practice began to change the quantity and distribution of flow from Taylor Slough into Northeastern Florida Bay. These practices altered salinity and hydrologic parameters that had measurable negative impacts on vertebrate fauna and their habitats. Here, I review those impacts from published and unpublished literature and anecdotal observations. Almost all vertebrates covered in this review have …
