Microbial Community Assembly Found With Sponge Orange Band Disease In Xestospongia Muta (Giant Barrel Sponge), Rebecca Mulheron Aug 2014

Microbial Community Assembly Found With Sponge Orange Band Disease In Xestospongia Muta (Giant Barrel Sponge), Rebecca Mulheron

HCNSO Student Theses and Dissertations

The giant barrel sponge, Xestospongia muta is an iconic and essential species of the coral reefs in South Florida. The sponge has primary roles providing ecosystem services and creating unique habitats for diverse microbial communities. On April 27, 2012 an outbreak of Sponge Orange Band Disease (SOB) was detected off the coast of South Florida. The disease begins with sponge bleaching, followed by mesohyl or “mesohyl” necrosis and often total mesohyl disintegration. Sampling from two diseased populations at Boynton Beach and Fort Lauderdale, FL took place on May 11th and May 29th, 2012. Each of the nine diseased sponges from …


Long-Term Stony Coral Transplantation Success Offshore Southeast, Florida, Usa, Theresa Elizabeth Robitaille Aug 2014

Long-Term Stony Coral Transplantation Success Offshore Southeast, Florida, Usa, Theresa Elizabeth Robitaille

HCNSO Student Theses and Dissertations

Transplanted coral (Order: Scleractinia) colony condition was surveyed at five injury event sites, two coral nurseries, and one impact minimization location off the coast of Broward County, Florida, USA in 2012. Because stony corals are long-lived and slow growing, generally growing less than one centimeter in diameter per year, determining transplantation success requires long-term (greater than two years) monitoring. Long-term monitoring efforts, however, are rarely completed. This study is unique in that it examined stony coral transplantation success of several projects over a time period of 6-17 years. Control colonies were also surveyed in order to compare naturally growing coral …


Loggerhead Sea Turtle (Caretta Caretta) Hatchling Disorientation In Broward County, Florida, Allison Durland Donahou Jul 2014

Loggerhead Sea Turtle (Caretta Caretta) Hatchling Disorientation In Broward County, Florida, Allison Durland Donahou

HCNSO Student Theses and Dissertations

Hatchling disorientation after emergence is a major factor impacting sea turtle populations. This study utilized data from over 1,200 Florida Fish and Wildlife Conservation Commission (FWC) Marine Turtle Disorientation Report forms from years 2006 to 2011 to assess changes in the severity and locations of disorientation events and the impact of municipal beach lighting ordinances. While the FWC forms were completed for all sea turtle species observed, this study focused only on loggerhead sea turtles (Caretta caretta). A Disorientation Severity Index (DSI) was derived from the number of hatchlings and the direction of their tracks leaving the nests …


Biophysical Interactions In The Straits Of Florida: Turbulent Mixing Due To Diel Vertical Migrations Of Zooplankton, Cayla Whitney Dean Jul 2014

Biophysical Interactions In The Straits Of Florida: Turbulent Mixing Due To Diel Vertical Migrations Of Zooplankton, Cayla Whitney Dean

HCNSO Student Theses and Dissertations

Diel vertical migrations (DVM) comprise the largest animal migration on the planet and are a phenomenon present in all bodies of water on Earth. A strong sound scattering layer undergoing DVM was observed in the Straits of Florida via a bottom-mounted Acoustic Doppler current profiler (ADCP) Workhorse Longranger 75 kHz (Teledyne RD Instruments) located at the 244 m isobath. ADCP average backscatter showed a clear periodicity corresponding with sunrise and sunset times indicating the presence of a nocturnal DVM. Analysis of the ADCP backscatter data indicated zooplankton swimming velocities were faster during sunrise than sunset times. In several cases the …

Reproduction And Population Of Porites Divaricata At Rodriguez Key: The Florida Keys, Usa, John Mcdermond Jan 2014

Reproduction And Population Of Porites Divaricata At Rodriguez Key: The Florida Keys, Usa, John Mcdermond

HCNSO Student Theses and Dissertations

Sexual reproduction in Porites divaricata (Le Sueur, 1820) was studied over a one year period (August, 2012 to August, 2013) in a shallow water (~2m depth) carbonate bank (also described as marginal) habitat at Rodriguez Key, a small island located 1.44 km off the east coast of Key Largo. Porites divaricata is a brooding, gonochoric species with peak reproductive output (planula release) occurring in March and at least a smaller event in May. This species showed an overall female to male sex ratio of 3.5:1. However, during peak reproduction, the sex ratio was 1.2:1. Spawning (sperm release) most likely occurred …


Ocean Current Measurements: Challenges And Opportunities In The Florida Current, William E. Baxley Mar 2013

Ocean Current Measurements: Challenges And Opportunities In The Florida Current, William E. Baxley

HCNSO Student Capstones

The water velocities offshore south Florida are dominated by the Florida Current, and these effects result not only from the tremendous flow of water between Florida and the Bahamas, but also from the eddies and other rotational components imparted by the change in flow direction from eastward to northward along the Florida Keys and the end of the peninsula. These currents have been measured for decades, with methods ranging from subsurface floats to acoustic Doppler current profilers (ADCPs) and surface current measuring radars. Data suggests that there is a large degree of variability in the mean flow, including significant vorticity …
