Symbiont Type And Photophysiology Of Acropora Loripes And Platygyra Daedalea Under Future Scenarios Of Rising Ocean Temperatures And Pco2, Lauren Howe-Kerr
Independent Study Project (ISP) Collection
Coral cover is declining at an alarming rate, and it is estimated that 60% of reefs worldwide may be lost by 2030. Elevated seawater temperatures and ocean acidification are contributing to an increase in the frequency and severity of bleaching events. These events disrupt the symbiosis between corals and their photosynthetic dinoflagellates (Symbiodinium spp). Relatively little is known about the ability of corals to acclimatize to changing environmental conditions or whether the rate of climate change is too fast for corals to keep up, limiting the accuracy of future predictions for reef resilience. However, the ability of some coral species …

Bacterial Indicators Of Fecal Pollution: Exploring Relationships Between Fecal Coliform And Enterococcus Groups In Central And South Florida Surface Waters, Shelby G. Craig
HCNSO Student Theses and Dissertations
Ambient and recreational surface waters worldwide experience fecal pollution due to a variety of anthropogenic sources. Fecal waste has been proven, for over a century, to harbor pathogenic microorganisms which subsequently cause a variety of disease and illness in human hosts. The benefits of utilizing fecal indicator bacteria (FIB) as a simple, inexpensive means to detect fitful human pathogens within a variety of water matrices are vast. However, no universal agreement exists in regard to which indicator is best suited for detection of fecal contamination and pathogens in environmental waters, and no single standard for bacterial indicators has been federally …

The Role Of Traditional Knowledge About And Management Of Seaworms (Polychaeta) In Making Austronesian Worlds, Cynthia Twyford Fowler
Faculty Scholarship
This paper discusses how Kodi make their worlds cognitively as well as experientially, and how these worlds relate to sustainability and wellbeing. Kodi construct their cognitive worlds as well as their biophysical landscapes whilst interacting with many other species. This presentation focuses on human-polychaete interactions in order to illustrate world making processes. Seaworm traditions have deep historical roots in Austronesian societies and continue to be crucial for the wellbeing of contemporary communities. World-making processes are evident in what Kodi people say about seaworms and how they move through space relative to seaworms. While Kodi construct time they simultaneously construct space …

Arts & Sciences Faculty Publications
The Atlantic sea scallop Placopecten magellanicus is an economically important species in the offshore fisheries on the east coast of the USA. Recently, animals collected from waters ranging from Massachusetts to Maryland have shown variably sized (up to 1 cm in diameter) orange nodular foci, predominantly in the adductor muscle tissue, but also in other organs. Histological evaluation of the nodular lesions showed rod-shaped bacteria that stain acid-fast positive and Gram-positive. PCR methodology was employed to identify the causative organism of the nodules as a Mycobacterium sp. using analysis of the partial 16S gene and the 16S-23S internal transcribed spacer …

Coral Genotype Influence On Growth And Stress Resistance In Acropora Cervicornis: Investigating Potential Energy Tradeoffs, Peter T. Grasso
HCNSO Student Theses and Dissertations
Over the last few decades coral reefs have faced unprecedented declines in health due to natural and anthropogenic sources. Until recently few studies have examined genotypic variation of growth and thermal stress resistance in Acropora cervicornis. This study aims to assess the potential for energy trade-offs between growth and thermal stress resistance by following 120 coral fragments from 12 genotypes of Acropora cervicornis over the course of 15 months to determine average growth rates for each genotype. Following the completion of the growth observation a bleaching event occurred in the lower Florida Keys providing the opportunity for examining thermal …

An Endemic Commensal Leucothoid Discovered In The Tunicate Cnemidocarpa Bicornuta, From New Zealand (Crustacea, Amphipoda), Kaitlyn M. Brucker
HCNSO Student Theses and Dissertations
Precise descriptions and comprehensive taxonomies of species and their ecology are essential in monitoring changes in marine biodiversity at multiple spatial scales. A currently undescribed species of commensal amphipod in the genus Leucothoe is reported from New Zealand, collected from the endemic tunicate Cnemidocarpa bicornuta. This species differs from others in the genus in having a one-articulate first maxilla palp and an apically produced tuberculate lobe on the inner margin of the outer plate of the maxilliped. Previous taxonomic surveys in New Zealand waters did not document this species, indicating that it may be a recent arrival. This research …

Dataset For: Simulating Cell Death In The Termination Of Karenia Brevis Blooms: Implications For Predicting Aerosol Toxicity Vectors To Humans, Jason M. Lenes
C-IMAGE data
A non-linear lysis term for simulation of K. brevis HAB termination on the West Florida Shelf is introduced, with the assumption that particle encounters of planktonic microalgae and bacteria can be described as the square of the phytoplankton biomass. This formulation also accounts for nutrient-limitation of K. brevis as a precondition for susceptibility to bacterial and viral attack, and potentially programmed cell death. Two model simulations were run of linear and non-linear lysis cases. Model output was compared against observed weekly maximum K. brevis concentrations, with statistical metrics calculated over three HAB phases during 2001. Introduction of the non-linear lysis …

Sponge Distribution And The Presence Of Photosymbionts In Moorea, French Polynesia, Christopher J. Freeman, Cole Easson
Marine & Environmental Sciences Faculty Articles
Photosymbionts play an important role in the ecology and evolution of diverse host species within the marine environment. Although sponge-photosymbiont interactions have been well described from geographically disparate sites worldwide, our understanding of these interactions from shallow water systems within French Polynesia is limited. We surveyed diverse habitats around the north coast of Moorea, French Polynesia and screened sponges for the presence of photosymbionts. Overall sponge abundance and diversity were low, with <1% cover and only eight putative species identified by 28S barcoding from surveys at 21 sites. Of these eight species, seven were found predominately in shaded or semi-cryptic habitats under overhangs or within caverns. Lendenfeldia chondrodeswas the only species that supported a high abundance of photosymbionts and was also the only species found in exposed, illuminated habitats. Interestingly, L. chondrodes was …

Distribution, Abundance And Movement Of Fish Among Seagrass And Mangrove Habitats In Biscayne Bay, Patrick C. Goebel
HCNSO Student Theses and Dissertations
Inshore tropical and subtropical estuaries harbor a relatively high abundance and diversity of organisms. Specifically within estuaries, mangrove and seagrass habitats provide shelter and food for a plethora of organisms, through some or all their life histories. Given the biological connection between offshore coral reefs and coastal estuaries, there is a critical need to understand the underlying processes that determine distribution and abundance patterns within mangrove-seagrass habitats. The predatory fish assemblage within the mangrove and seagrass beds of Biscayne Bay, Florida (USA), was examined over 24-hr. time periods along a distance and habitat gradient from the mangrove edge and nearshore …

Assessing The Impacts Of Oil-Associated Marine Snow Formation And Sedimentation During And After The Deepwater Horizon Oil Spill, Kendra L. Daly, Uta Passow, Jeffrey Chanton, David Hollander
Marine Science Faculty Publications
The Deepwater Horizon oil spill was the largest in US history, unprecedented for the depth and volume of oil released, the amount of dispersants applied, and the unexpected, protracted sedimentation of oil-associated marine snow (MOS) to the seafloor. Marine snow formation, incorporation of oil, and subsequent gravitational settling to the seafloor (i.e., MOSSFA: Marine Oil Snow Sedimentation and Flocculent Accumulation) was a significant pathway for the distribution and fate of oil, accounting for as much as 14% of the total oil released. Long residence times of oil on the seafloor will result in prolonged exposure by benthic organisms and economically …
