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 …
The Ecology And Economics Of Seagrass Community Structure, Bryan Dewsbury
The Ecology And Economics Of Seagrass Community Structure, Bryan Dewsbury
FIU Electronic Theses and Dissertations
Coastline communities have experienced a marked increase in human populations over the last few decades. This increase in population places disproportionate pressure on coastal ecosystems to provide economic services to support local economies. At the same time, overuse of these services can aid in the destruction of the ecosystems responsible for them. Seagrass ecosystems are mainly found near coastlines, and are typically a chief provider of some of these economic goods and services. Many previous studies have documented the ecological functions of this seagrasses. Unfortunately, our increasing knowledge of seagrass structure and function has not been fully incorporated into economic …
