Show moreThe projects described in this dissertation concentrated on investigating Caribbean species for qualitative and quantitative chemical differences. Chapter one includes a brief update on the status of natural products as drugs, a discussion of the biodiversity of Caribbean marine organisms as well as a discussion about the chemistry of algae and sponges. In chapter two, an experiment to test for possible effects of warmer, more acidic water and how that will impact coral reef organisms was conducted. Six common Caribbean coral reef sponge species were grown in seawater for 24 days ranging from values experienced at summer-maxima (temperature = 28 ºC; pH = 8.1) to those predicted for the year 2100 (T = 31 ºC; pH = 7.8). For each species, attachment rates, growth, and survival were similar between temperature and pH levels. Only two metabolite concentrations varied significantly between treatments but were similar to baseline levels. In chapter three, a chemical survey of Florida Keys algae was performed using MeOH extraction and HP-20 SPE with varying Me2CO:H2O solutions. 1H NMR spectra were collected for each fraction and analyzed for interesting signals. A Laurencia sp. was extracted and found to contain the known compound isodactylyne (61) with the structure determined using spectroscopic analyses. In chapter four, a Laurencia obtusa specimen was investigated to determine the compound causing oxygenated signals between 4.50 – 4.80 ppm in the 1H NMR spectra observed in chapter three. A large scale extraction and fractionation was performed and the compound was determined to be 1-O-palmitoyl-2-O-myristoyl-3-O-(6-sulfo-α- D-quinovo-pyranosyl)-glycerol (63). In chapter five, the isolation and structural elucidation of a new compound, furocaespitanenone (64) and two known compounds (10R)- and (10S)-10-O-methylfurocaespitanelactol 65 and 66, from a Laurencia sp. collected off of the Florida Keys using MeOH extraction and HP-20 column chromatography is described. A potential biosynthesis of 64 from furocaepsitane (68) is proposed.

Title: Effects of Electromagnetic Hydrolysis on Dissolved Oxygen in Small Ponds.
Creator: Iles, Matthew, Bloetscher, Frederick, Florida Atlantic University, College of Engineering and Computer Science, Department of Civil, Environmental and Geomatics Engineering
Abstract/Description: This pilot study was conducted to determine if an Electron Magnetics Oxygen and Hydrogen (EMOH) device can increase the dissolved oxygen (DO) concentration of a residential surface water. By using EMOH, DO concentration will increase and allow bacteria to remove the substrate that creates blue-green algae for which the City of Boynton Beach (City) receives complaints. Those complaints center on odors and the visual appearance of the ponds. The study was conducted in-situ at the INCA Pond...
Show moreThis pilot study was conducted to determine if an Electron Magnetics Oxygen and Hydrogen (EMOH) device can increase the dissolved oxygen (DO) concentration of a residential surface water. By using EMOH, DO concentration will increase and allow bacteria to remove the substrate that creates blue-green algae for which the City of Boynton Beach (City) receives complaints. Those complaints center on odors and the visual appearance of the ponds. The study was conducted in-situ at the INCA Pond system in the City of Boynton Beach, Florida with data collection taking place bi-weekly, using surface aeration techniques. Water sampling was conducted in the INCA Pond system via a handheld water sensor. Primary variable monitored included: water temperature, barometric pressure, DO concentration, and DO saturation (DOSAT). Biomass of dead algae at the bottom of the pond was also monitored to determine if increased DO concentration aided the biological digestion of the organic matter. Data analysis shows that exposure to EMOH treatment allowed the relationship between DO and temperature to change from a negative correlation (the expected relationship) to a positive trend. Furthermore, pressure and DOSAT became less correlated after exposure to EMOH effluent. In all, EMOH was shown to be an effective means of treating hypoxic pond water. The optimal EMOH effluent discharge is determined to be deep in the subject pond. Backed by research on the surface-air water and bubble-water oxygen transfer coefficients, DO concentration in the subject pond was 110% higher when effluent was directed down toward the floor of the pond.

Title: Ocean Acidification Effects on Photosynthesis in Tropical Marine Macroalgae.
Creator: Zweng, Regina C., Koch, Marguerite, Florida Atlantic University, Charles E. Schmidt College of Science, Department of Biological Sciences
Abstract/Description: Field data from CO2 vents, a current model of future ocean acidification conditions, show a positive correlation between elevated seawater pCO2 and fleshy macroalgal abundance, as well as a negative correlation between elevated seawater pCO2 and calcareous macroalgal abundance on coral reefs. One underlying physiological mechanism for increases of fleshy macroalgae species in response to greater pCO2 could be an increase in their photosynthesis. Furthermore, inorganic carbon use mechanisms,...
Show moreField data from CO2 vents, a current model of future ocean acidification conditions, show a positive correlation between elevated seawater pCO2 and fleshy macroalgal abundance, as well as a negative correlation between elevated seawater pCO2 and calcareous macroalgal abundance on coral reefs. One underlying physiological mechanism for increases of fleshy macroalgae species in response to greater pCO2 could be an increase in their photosynthesis. Furthermore, inorganic carbon use mechanisms, irradiance and depth may influence species-specific responses to ocean acidification. Therefore, this thesis aimed to discern carbon use strategies and photosynthetic responses to elevated pCO2 of dominant tropical fleshy and calcareous macroalgae. All species studied were able to utilize HCO3 - for photosynthesis. 33% of calcifying macroalgae and 80% of fleshy macroalgae had increased photosynthetic rates in response to lower pH. Thus, future conditions of OA may perpetuate or exacerbate the abundance of fleshy seaweeds at the expense of calcareous species.

Title: The impacts of harmful algal blooms on a Florida reef fish community.
Creator: Baumberger, Rex E., Jr., Charles E. Schmidt College of Science, Biology
Abstract/Description: Coral reefs worldwide are threatened by many environmental disturbances including harmful algal blooms (HABs) which have been increasing on Florida coasts over the past decade. Research has mainly focused on HAB identification, percent cover and other effects on the benthos but the relationship of HABs with upper trophic levels has received less attention. To study this relationship, a two-year investigation on a 10-m deep reef off of Hallandale Beach, was conducted. Stationary fish census...
Show moreCoral reefs worldwide are threatened by many environmental disturbances including harmful algal blooms (HABs) which have been increasing on Florida coasts over the past decade. Research has mainly focused on HAB identification, percent cover and other effects on the benthos but the relationship of HABs with upper trophic levels has received less attention. To study this relationship, a two-year investigation on a 10-m deep reef off of Hallandale Beach, was conducted. Stationary fish census coupled with benthic transect videos were conducted quarterly between April 2005-July 2007. A significant correlation between Lyngbya sp. blooms and alterations in fish assemblages was observed. Lyngbya had a negative interaction with fish species and abundance; additionally, HAB sample periods were significantly different from low algal abundance periods. Blooms of Dictyota sp. had no measurable relationship with the fish assemblage indicating HABs may have variable impacts on fishes depending on family, species and chemistry of the algae.
