Variation In Coral Recruitment And Juvenile Distribution Along The Southeast Florida Reef Tract, Leah M. Harper
Variation In Coral Recruitment And Juvenile Distribution Along The Southeast Florida Reef Tract, Leah M. Harper
HCNSO Student Theses and Dissertations
Coral recruitment in Southeast Florida is being outpaced by mortality, resulting in population declines in many species. Identifying the coral species most likely to recruit and survive on Southeast Florida reefs and evaluating spatial variation in recruitment and survivorship is crucial for managing decreasing coral populations. This study focuses on 12 sites in Broward and Miami-Dade counties that have served as long-term stations for monitoring adult coral cover and demographics. At each site, thirty-two 225cm2 grooved terracotta settlement tiles were attached to the substrate in winter of 2015 and retrieved in winter of 2016 to evaluate scleractinian and octocoral …
Copper Tolerance Of Amphibalanus Amphitrite As Observed In Central Florida, Hannah Grace Brinson
Copper Tolerance Of Amphibalanus Amphitrite As Observed In Central Florida, Hannah Grace Brinson
Theses and Dissertations
Copper tolerance in the invasive barnacle Amphibalanus amphitrite has been observed in Florida by the Center for Corrosion and Biofouling Control since 2012 and by Weiss (1947). To test the theory that this barnacle preferentially settles on copper coated surfaces to avoid settlement competition by other sessile species, a series of two experiments and a literature review of historical copper toxicity tests on larval barnacles was conducted. The barnacle A amphitrite was preferentially used in many previous toxicity studies because it is readily available, has high fecundity, and is more sensitive to some toxicants than other species, including the native …
Presence/Absence And Density Data For Epipelagic Tows From 48 Stations In The Northern Gulf Of Mexico From R/V Blazing Seven Cruises Lf2015a And Lf2015b June 2015 And July 2015, Jay R. Rooker, R.J. David Wells
Presence/Absence And Density Data For Epipelagic Tows From 48 Stations In The Northern Gulf Of Mexico From R/V Blazing Seven Cruises Lf2015a And Lf2015b June 2015 And July 2015, Jay R. Rooker, R.J. David Wells
DEEPEND Datasets
Larval catch data after the oil spill is being used to improve our understanding of the causes of temporal variability as it relates to the Deep Water Horizon oil spill (DWHOS). Bongo and neuston net tows were conducted at 48 stations in both June and July, 2015 in the northern Gulf of Mexico. Cruise data collected at each site included latitude/longitude, date, time and environmental data (temperature, salinity, dissolved oxygen). The occurrence and density of selected epipelagic (e.g., billfishes, tunas, dolphinfishes, flyingfishes) and deep pelagic (e.g., lanternfishes, bristlemouths, marine hatchetfishes) fish larvae were quantified and are being used to extend …

Development Of An Age-Frequency Distribution For Ocean Quahogs Arctica Islandica On Georges Bank, Sara M. Pace, Eric N. Powell, Roger Mann, M. Chase Long, John M. Klinck

Ocean quahogs [Arctica islandica (Linnaeus, 1769)] are the longest-lived, noncolonial animal known today, with a maximum life span exceeding 500 y. Ocean quahogs are a commercially important bivalve, inhabiting the continental shelf of the North Atlantic Basin. Although considerable information exists on the growth and physiology of A. islandica, limited information is available regarding recruitment; accordingly, sustainably managing the fishery is a challenge. To investigate long-term recruitment trends, the age of ocean quahogs from Georges Bank which were fully recruited to the commercial fishery (>80 mm shell length) was determined by analysis of annual growth lines in …
