This research investigates the distribution and population structure of crustaceans, endemic to anchialine systems in the tropical western Atlantic focusing on cave-dwelling shrimp from the family Barbouriidae. Taxonomic and molecular tools (genetic and genomic) are utilized to examine population dynamics and the presence of phenotypic hypervariation (PhyV) of the critically endangered species Barbouria cubensis (von Martens, 1872). The presence of PhyV and its geographic distribution is investigated among anchialine populations of B. cubensis from 34 sites on Abaco, Eleuthera, and San Salvador, Bahamas. Examination of 54 informative morphological characters revealed PhyV present in nearly 90% (n=463) of specimens with no …

Coastal groundwater aquifers are susceptible to saltwater intrusion from natural and anthropogenic sources. Everglades National Park (ENP) has been adversely impacted by past human activities that altered freshwater flow through the system. In Big Pine Key (BPK), the flat and low-lying topography less than 2m makes the freshwater lens vulnerable to tidal and storm surge events. This study investigated different inversion scenarios and used Electrical Resistivity Tomography (ERT) and Electromagnetic (EM) survey to characterize the spatial and temporal change of the groundwater chemistry and image the aquifers. In Big Pine Key, Hurricane Irma made landfall as a category 4 storm …
An Economic Assessment Of The Impacts Of Outdoor Water Use Restrictions In South Florida, Lara Kiesau
An Economic Assessment Of The Impacts Of Outdoor Water Use Restrictions In South Florida, Lara Kiesau
FIU Electronic Theses and Dissertations
Population growth and climate change are important factors determining residential water demand. Most residential water consumption can be attributed to outdoor use. To reduce water consumption, outdoor water use restrictions (OWRs) have become a popular policy tool in the last decades. We developed an integrated framework consisting of a Difference in Differences (DID) analysis, Value Function approach and Discrete Choice Model to perform an economic assessment of the impacts of OWRs in South Florida. The results reveal a decreasing effect of up to 133 gallons per person per month due to the strictest OWR, equaling a yearly value of almost …

Developing a self-sufficient water supply system in Southeast Florida is one input to the success of the ongoing restoration effort in the Everglades. Maintaining a high groundwater level in the urban side of the Biscayne Aquifer (BA) is important to sustain the urban water supply. However, the long-term groundwater table condition in the Biscayne Aquifer (BA) is threatened by a combination of drought, groundwater pumping, and sea-level rise. Further, the long-term drought pattern, drought drivers, and the aquifer’s response to drought and other stress conditions are not well known. As a result, options that would help to maintain a high …
