Understanding The Genomic Influence And Virulence Capabilities Of Environmentally Isolated Vibrios, Shannon Elizabeth Pipes
Understanding The Genomic Influence And Virulence Capabilities Of Environmentally Isolated Vibrios, Shannon Elizabeth Pipes
Theses and Dissertations
The genus Vibrio consists of Gram-negative bacteria that possess a curved rod shape and are routinely isolated from estuarine and coastal salt water. Vibrio cholerae, Vibrio parahaemolyticus, and Vibrio vulnificus are the major three species that contribute to human disease worldwide, and a variety of other Vibrio species contribute to persistent problems in the aquaculture and fishing industries. The CDC estimates that vibrios cause 80,000 cases of disease each year in the United States alone, however, this number is thought to be underestimated, since some disease is only self-limiting, meaning patients may not seek medical treatment and have …
Panoramic Spatial Vision In The Bay Scallop Argopecten Irradians, Daniel R. Chappell, Tyler M. Horan, Daniel Isaac Speiser
Panoramic Spatial Vision In The Bay Scallop Argopecten Irradians, Daniel R. Chappell, Tyler M. Horan, Daniel Isaac Speiser

We have a growing understanding of the light-sensing organs and light-influenced behaviours of animals with distributed visual systems, but we have yet to learn how these animals convert visual input into behavioural output. It has been suggested they consolidate visual information early in their sensory-motor pathways, resulting in them being able to detect visual cues (spatial resolution) without being able to locate them (spatial vision). To explore how an animal with dozens of eyes processes visual information, we analysed the responses of the bay scallop Argopecten irradians to both static and rotating visual stimuli. We found A. irradians distinguish between …
Characterizing The Temporal And Spatial Distribution Of The Cannonball Jellyfish (Stomolophus Meleagris) In The South Atlantic Bight, Lauren G. Faulk
Characterizing The Temporal And Spatial Distribution Of The Cannonball Jellyfish (Stomolophus Meleagris) In The South Atlantic Bight, Lauren G. Faulk
Theses and Dissertations
The cannonball jellyfish, Stomolophus meleagris, is commercially harvested throughout its range in the tropical and sub-tropical Americas, including in the South Atlantic Bight, where an estimated 4,000 tons (less than 2.4% of the estimated stock in South Carolina during the spring) are harvested annually. Like many Scyphozoan jellyfish, cannonball jellies have high interannual variability and little is known about the environmental drivers of their distribution and phenology. To better understand the ecology of this targeted species, we used fisheries-independent abundance data of cannonball jellyfish from 2001 to 2019 collected by the Southeast Area Monitoring and Assessment Program (SEAMAP) throughout the …
Cyclic Fluctuations Of Zooplankton Dynamics In A Tidal Salt-Marsh Basin, Jamaal Jacobs
Cyclic Fluctuations Of Zooplankton Dynamics In A Tidal Salt-Marsh Basin, Jamaal Jacobs
Senior Theses
Zooplankton are pelagic aquatic animals that are limited in their movements by the water currents around them and are major links in aquatic food webs between primary producers and higher trophic levels. Their populations are temporally and spatially variable, as they are sensitive to changes in salinity, temperature, and dissolved oxygen. This is especially true in highly dynamic environments, like estuaries, where environmental conditions are highly variable across seasonal and daily cycles. In order to examine the variability in zooplankton populations across a tidal cycle, we collected zooplankton samples from North Inlet Estuary at 30-minute intervals over a half tidal …
Ordination Obscures The Influence Of Environment On Plankton Metacommunity Structure, Tad Dallas, Andrew M. Kramer, Marcus Zokan, John M. Drake
Ordination Obscures The Influence Of Environment On Plankton Metacommunity Structure, Tad Dallas, Andrew M. Kramer, Marcus Zokan, John M. Drake
Faculty Publications
The composition of plankton communities in individual habitats is often influenced by environmental conditions like pH or hydroperiod. At larger scales, environmental gradients can influence community structure across interconnected local communities. Detecting the role of environmental and spatial factors on metacommunity structure depends on the ordering of sites and species prior to analysis. We investigated this ordination in two wetland metacommunities; a well-sampled, hyper-diverse zooplankton metacommunity, and a Central American phytoplankton metacommunity. We calculated coherence, turnover, and boundary clumping to classify the structure of the metacommunity, and we propose a statistic that responds to variation in both coherence and turnover. …
Co-Extinction In A Host-Parasite Network: Identifying Key Hosts For Network Stability, Tad Dallas, Emily Cornelius
Co-Extinction In A Host-Parasite Network: Identifying Key Hosts For Network Stability, Tad Dallas, Emily Cornelius
Faculty Publications
Parasites comprise a substantial portion of total biodiversity. Ultimately, this means that host extinction could result in many secondary extinctions of obligate parasites and potentially alter hostparasite network structure. Here, we examined a highly resolved fish-parasite network to determine key hosts responsible for maintaining parasite diversity and network structure (quantified here as nestedness and modularity). We evaluated four possible host extinction orders and compared the resulting co-extinction dynamics to random extinction simulations; including host removal based on estimated extinction risk, parasite species richness and host level contributions to nestedness and modularity. We found that all extinction orders, except the one …
