Show moreMusicians and non-musicians were evaluated during pilot testing of the Visual Oddball and Go/No-Go as measured with P3 event-related potentials. Amidst COVID-19, we are collecting online questionnaire data with a sample of 34 participants, which will be tested in-person once safety protocols are established. Factors from the Brief Music Experience Questionnaire were correlated to variables from a Basic Information Questionnaire. For the Oddball and Go/No-Go testing, lower reaction times were observed for two musicians as well as higher accuracy on the Oddball task. Musicians demonstrated higher amplitudes and later peak latencies for the Go/No-Go, but lower amplitudes and later peak latencies for the Oddball. Preliminary correlations were found between years playing an instrument, and proficiency playing an instrument with innovative musical aptitude and reactive musical behavior components. Upon collecting more data, differences are expected in cognition between musicians and non-musicians during tasks of stimulus evaluation and inhibition.

Prominent carvings include dual four leaf clover designs and a zoomorphic hook. Margate-Blount was discovered in 1959 by former Pompano Beach Mayor Bruce Blount, who found a wooden crypt filled with skeletons after engineers bulldozed the area he was leasing. Archaeologists began to study the site north of Northwest 72nd Street and west of University Drive. Subsequent digs were conducted through 2002. Items pulled over the years include ceramics, shells, antlers, carved animal bones, shark teeth and a shark vertebrae. It's one of about 500 Indian archaeological sites scattered everywhere from along the beach in Fort Lauderdale all the way out to Weston and the Everglades.

Title: Monitoring coral bleaching and disease through the Southeast Florida Action Network BleachWatch program.
Name/Creator: Camden, Lauren
Abstract/Description: Corals are made up of many animals called coral polyps, which receive ninety percent of their food and energy through photosynthesis from microscopic algae living within them called zooxanthellae. These algae have a symbiotic relationship with coral, both relying on each other to survive. The zooxanthellae give corals their characteristic colorful appearance. However, when placed under stress coral expel their zooxanthellae, exposing their white tissue and skeletons, and losing their main...
Show moreCorals are made up of many animals called coral polyps, which receive ninety percent of their food and energy through photosynthesis from microscopic algae living within them called zooxanthellae. These algae have a symbiotic relationship with coral, both relying on each other to survive. The zooxanthellae give corals their characteristic colorful appearance. However, when placed under stress coral expel their zooxanthellae, exposing their white tissue and skeletons, and losing their main food source. This is called coral bleaching and has been occurring in increasing severity in the last twenty years. Mass bleaching events have been increasingly observed where a wide range of species bleach over a large area of reef. These mass bleaching events have been correlated to rising sea surface temperatures that cause the coral thermal stress. A rise in temperature of only one to two degrees Celsius can trigger bleaching events, and when long term averages are raised, mass bleaching is more likely to occur. This can cause eventual mortality if environmental stressors are not resolved quickly enough to give corals a chance to recover. Disease is the second part of the two-part threat causing coral casualties in the tropical Atlantic and wider Caribbean region. Beginning in the 1970s, disease has been observed at staggering levels worldwide and is the result of a bacteria, virus, fungus, or abnormal growth. In the Florida Reef Tract, this can present as black band disease, stony soral tissue loss disease, or tumors. It is identified by a change in tissue color or structure and causes tissue loss and eventual mortality. BleachWatch is a program designed to detect and monitor coral bleaching events and disease outbreaks in the Florida Reef Tract and serve as an early warning system for bleaching events. Southeast Florida Action Network (SEAFAN) in conjunction with the Florida Department of Environmental Protection developed the SEAFAN BleachWatch program in 2013 as a compliment to the Florida Keys BleachWatch program managed by Mote Marine Laboratory and the Florida Keys National Marine Sanctuary. The northernmost one-third of the Florida Reef Tract is in the SEAFAN BleachWatch program’s jurisdiction, beginning at the end of Biscayne National Park, and ending at the Hobe Sound National Wildlife Refuge. BleachWatch consists of a combination of oceanographic data and field observations recorded by an Observer Network made up of trained volunteers and scientists that are used to generate a Current Conditions Report monthly, weekly, or bi-weekly, depending on conditions. The National Oceanic and Atmospheric Administration’s Coral Reef Watch is used to predict likelihood of future bleaching events and alerts are sent out to the Observer Network if a risk of bleaching is deemed. Participants then complete and submit data sheets to be used in the next Current Conditions Report. In 2019, three such reports were generated in July, September, and October. Sea surface temperatures remained consistently above monthly averages in two-thirds of the reports, and bleaching and disease were consistently reported, especially in Broward County. However, participation was low, with only nineteen data sheets being submitted over the entire annual period. More participation and submitted data sheets are greatly needed for more accurate results and better analysis. Still, the program has helped to improve scientific understanding regarding the timing, distribution, and severity of disease and bleaching in southeast Florida. It also gives citizen scientists the chance to be involved in collecting data to enable the restoration of their local reefs and enables assessment of the health of the Florida Reef Tract while providing an outlook for potential future events. Current Condition Reports aid in making responsible management decisions by the Florida Department of Environmental Protection and the Florida Keys National Marine Sanctuary regarding Florida’s beautiful and invaluable coral reef ecosystems.

Title: A case study of ocean acidification and South Florida’s coral reefs.

Abstract/Description: Levels of the greenhouse gas carbon dioxide have been increasing dramatically in the atmosphere since the onset of the Industrial Revolution with a sharp escalation occurring due to anthropogenic causes such as the burning of fossil fuels.

Show moreLevels of the greenhouse gas carbon dioxide have been increasing dramatically in the atmosphere since the onset of the Industrial Revolution with a sharp escalation occurring due to anthropogenic causes such as the burning of fossil fuels. The ocean acts as a carbon sink for this atmospheric CO2, absorbing a large majority of it. This process causes a chemical reaction that has been increasing the acidity level of ocean water and progressively lowering the average pH value. When a carbon dioxide molecule is absorbed into sea water, two positively charged ions are produced. Because pH value is a measurement of hydrogen ion concentration in any given solution, these added hydrogen ions effectively lower the pH value of the ocean. Since these hydrogen ions are positively charged, they go on to interact with the negatively charged bases already present in the ocean. One of these bases is CaCO3, or the carbonate ion. Carbonate is essential to calcifying marine organisms, who use this ion to build and maintain their shells and skeletons. However, as atmospheric carbon dioxide levels increase and the resulting chemical reactions occur, the ocean’s carbonate saturation decreases. Coral is one such calcifying organism that essential to the aquatic ecosystem in a number of ways, most of which can be attributed to the fact that coral reefs are one of the planet’s most biodiverse ecosystems despite inhabiting only a very small portion of the ocean. Several studies have linked coral’s carbonate production to their ability to create functional skeletons. One such study was published by Kuffner et al in 2013 in the Florida Keys. Four sites ranging from Miami to the Dry Tortugas were selected, and two batches of forty Siderastrea siderea (massive starlet coral) each were selected for two experimental runs. At six-month intervals, these samples were analyzed to determine linear expansion rates and calcification levels. After analysis in both runs, a strong correlation between linear expansion rates and calcification levels was determined. Corals that experienced heightened calcification rates also experienced heightened linear expansion. This experiment solidified the negative affect ocean acidification will have in future years on coral reefs if left unacknowledged. Langdon et al also published an experiment done in the Florida Keys in 2013 that determined a relationship between increased atmospheric CO2 levels and decreased calcification rates of coral. Eleven samples of a combination of Siderastrea radians (shallow water starlet coral) and Solenastrea hyades (smooth star coral) were epoxied to cinderblocks with sensors recording environmental data at thirty-minute intervals. Random samples were incubated in tanks in situ and given a treatment regime designed to simulate increased ocean acidification conditions through chemical injections of NaHCO3 (sodium bicarbonate) and HCl (hydrogen chloride). This treatment lowered pH value in the incubation chambers by 0.1 to 0.2 units. Calcification rates of the incubated coral samples were determined through statistical analysis. Coral samples that experienced a 0.1 unit drop in pH value experienced decreased calcification rates of 50% and coral samples that experiences a 0.2 unit drop in pH value experienced a decreased calcification rate of 52%. Both of these studies combined showcases the two-part threat ocean acidification is placing on coral reefs in the Florida Keys. As the average pH of ocean water drops, corals are unable to achieve net carbonate accretion and calcification rates drop. This causes corals to experience stunted linear expansion, density, rugosity, and reproduction rates. As coral population dwindles, Florida will experience several negative socio-economic impacts such as diminished coastal protection from storms, tourism, income and jobs created by fisheries, and medicinal opportunities as new life-saving medicines will no longer be able to be harvested from dying reefs. Mitigation and adaptation methods must include reducing other local stressors to coral.

Show moreQueen conch (Lobatus gigas) have been experiencing low reproduction rates throughout their distribution. Imposex female conchs have been observed with male verges in the British Virgin Islands and have been linked to areas of high boating activity. While in the Florida Keys, reduced reproduction has been linked to Lobatus gigas located in nearshore habitats. This literature review will evaluate the most effective method to determine a cause for reproductive failure in Lobatus gigas. In the British Virgin Islands, Cassander Titley-O’Neal analyzed imposex females and performed a butylin analysis on the digestive glands and food resources within the habitat the conch were collected. Titley-O’Neal recognized imposex morphology in Lobatus gigas and collected samples based on these features in areas of high boating activity, using reproductively normal conch from areas of low boating activity as reference. Gabriel Delgado compared the gonadal tissue and cerebral ganglia cell diameter and density of non-imposex queen conch offshore and nearshore in the Florida Keys. In the La Parguera area of Puerto Rico, Shawna E. Reed compared the gonads of imposex females to normal female conch gonads. Low concentrations of Tributyltin (TBT) in the turtle grass and marine algae samples taken by Titley-O’Neal, suggested food source is not enough uptake of TBT to cause imposex in Lobatus gigas. The presence of TBT was found in both male and female digestive glands, and in all sites, except one reference site, Anegada, but was highest in boating active sites. Concentration of Tributyltin was observed to be higher in male conch compared to females of the same area. The nearshore male and female queen conch of the Florida Keys were found to have less than 50% developed gametogenic tissue resulting in more than half being sexually inactive. The offshore population were observed to be highly reproductive with over 50% developed oogenic tissue in females and over 75% spermatogenic tissue in males. Delgado concluded that there appears to be abnormalities in the cerebral ganglion (c.g. responsible for hormone production) and deficiencies in the gonads of nearshore conch, both associated with reproduction. Given there was no environmental samples taken, there is no confirmed environmental or physical source for the cause of the abnormality in nearshore conch, other than the closer geographic proximity to anthropogenic factors. Reed compared imposex gonads to the gonads of normal reproducing females and determined no difference in sexual tissue. Imposex females demonstrated no male-like behavior. One imposex female was collected near an egg mass and had emptied signet cells, indicating successful reproduction. After evaluating each method, it appears abnormalities in cerebral ganglia, and deficiencies in gonads have been more successful in providing reason for reproductive failure in Lobatus gigas, compared to looking at masculinized females. Imposex has not yet been proven to have a negative effect on conch reproduction other than hypothesized issues regarding eggs masses as of present. Further study in the spawning of normal and imposex queen conch, with specific attention to their egg masses and habits, can potentially link imposex to failing reproduction among aggregations. Butlytin analysis on the gonads of queen conch may determine a link between Tributyltin concentration and delay in gametogenic tissues. Further research in water quality and sediment sampling to detect TBT in habitats of Lobatus gigas spawning.
