AGE STRUCTURE, REPRODUCTION, AND RECRUITMENT OF ATLANTIC STURGEON (<i>Acipenser oxyrinchus</i>) AND SHORTNOSE STURGEON (<i>Acipenser brevirostrum</i>) IN THE COOPER RIVER, SOUTH CAROLINA
This study investigated the age structure, recruitment, and reproduction of two endangered anadromous fish species, Atlantic Sturgeon (<i>Acipenser oxyrinchus</i>) and Shortnose Sturgeon (<i>Acipenser brevirostrum</i>), ... -
Investigation of the population genetic structure, salinity tolerance, and occurrence of a parasite in the island apple snail, <i>Pomacea maculata</i>, in South Carolina, USA
The island apple snail, <i>Pomacea maculata</i> (Gastropoda:Ampullariidae), is an invasive freshwater gastropod native to South America that is currently established in several southeastern states, including South Carolina. ... -
Age and Size Dependency of Spawning, and Effects on Egg Production, in Gag and Scamp Grouper off the Southeastern U.S.A.
Stock assessments have historically used spawning stock biomass as a proxy for reproductive output in marine fishes, assuming an invariant number of batches spawned per female fish. The number of batches spawned has been ... -
Cryptic lineages and hybridization in a cosmopolitan marine invertebrate
Some biological invasions pose a severe threat to marine coastal ecosystems, but can be difficult to track due to inaccurate species identifications and unrecognized cryptic diversity. Expanding on the published work of ... -
The Removal of Microplastics by Wastewater Treatment Plants in Charleston, SC and a Survey of Treatment Processes
Wastewater treatment plants (WWTPs) serve to collect and treat wastes that are known to include microplastic (MP) particles, fibers and microbeads. WWTPs are often suspected as a source of MPs into the marine environment, ... -
SEASONAL DISTRIBUTION AND HABITAT USE OF THE FLORIDA MANATEE (<i>TRICHECHUS MANATUS LATIROSTRIS</i>) IN SOUTH CAROLINA, U. S. A. FROM 1903-2015
Since as early as 1975, the South Carolina Department of Natural Resources (SCDNR) has been collecting opportunistic sightings of the Florida manatee (<i>Trichechus manatus latirostris</i>) in South Carolina. Despite this ... -
EFFECTS OF MODEL DESIGN AND ENVIRONMENTAL VARIABLES ON JUVENILE U.S. SOUTH ATLANTIC KING MACKEREL (<i>Scomberomorus cavalla</i>) ABUNDANCE
As growing human populations put an increasing demand on finite ocean resources, fisheries management tools rely ever more on high quality inputs and a comprehensive understanding of model factors. Stock assessment modeling ... -
Invasive Lionfish Biology Between Two Regions of the Western Atlantic and Caribbean
Invasive lionfish (<i>Pterois spp</i>.) were first detected off the coast of Florida in the 1980s and since then have spread throughout the western Atlantic and the Caribbean. Lionfish consume other fish species as well ... -
SPATIAL AND TEMPORAL VARIATION IN MERCURY BIOACCUMULATION OF A COMMONLY CONSUMED FRESHWATER FISH REDBREAST SUNFISH (<i>Lepomis auritus</i>)
Spatial and temporal patterns of mercury (Hg) concentrations were analyzed in tissue samples of redbreast sunfish (<i>Lepomis auritus</i>) and bluegill sunfish (<i>Lepomis macrochirus</i>) from the Congaree River, Columbia, ... -
CAN WOMEN EFFECTIVELY TACKLE CLIMATE CHANGE IN THE OFFICE? UNDERSTANDING THE GENDER DYNAMICS IN ENVIRONMENTAL AGENCIES
As climate change becomes a major concern for many governments and industries, the ability to communicate and discuss climate change in the workplace is vital. Previous research indicates that even though women show greater ... -
EVALUATION OF STATE HAZARD MITIGATION PLANS: AN ASSESSMENT OF PLAN QUALITY AND STAKEHOLDER INVOLVEMENT
Plan quality serves as the primary foundation for successful hazard mitigation practices, yet there is little research that investigates the impact of stakeholders on state hazard mitigation plan quality. The objective of ... -
FORECASTING ALLERGENIC POLLEN LEVELS THROUGH SPATIALLY-BASED REGRESSION MODELING
The south-central United States has many allergenic plants that cause allergic respiratory disease. Current pollen forecasts methods have short-term predictive ability and fail to capture environmental variation. Advanced ... -
EVALUATING THE EFFECTIVENESS OF A RECYCLING INITIATIVE FOR COLLECTING SHUCKED SHELL FROM RESTAURANTS IN THE BEAUFORT REGION OF SOUTH CAROLINA ORGANIZED AS A FOR-PROFIT BUSINESS
Oysters are a crucial species in the estuarine waters of South Carolina, as well as the majority of the United States. Overfishing, pollution, and disease have had devastating negative effects on oyster populations around ... -
IMPACT OF VITAMIN B12 AND NITRATE ON DIMETHYLSULFONIOPROPIONATE (DMSP) CONCENTRATIONS IN <i>PHAEODACTYLUM TRICORNUTUM</i> AND <i>THALASSIOSIRA PSEUDONANA</i>
Phytoplankton play countless roles in the support and regulation of marine ecosystems, as well as in global biogeochemical processes. One such process in the global sulfur cycle is the pathway, which is hypothesized to ... -
Effects of venting and recompression on post-release behavior of snapper-grouper species
Many traditional fisheries management regulations result in regulatory discards, which may experience mortality due to factors such as barotrauma. This study investigated the effects of common catch-and-release procedures ... -
SPERMATOGENESIS ZONALITY AND AGE OF SEXUAL MATURITY IN MALE COMMON BOTTLENOSE DOLPHINS (<i>Tursiops truncatus</i>) STRANDED IN SOUTH CAROLINA, USA
The common bottlenose dolphin (<i>Tursiops truncatus</i>) is the most frequently stranded marine mammal in the southeastern United States. Age of sexual maturity is an important life history parameter used to plan and ... -
POPULATIONS OF THE GREEN PORCELAIN CRAB, <i>Petrolisthes armatus</i>, VARY IN COLD TOLERANCE WITHIN THE SPECIES’ NORTHERNMOST INVADED RANGE
The green porcelain crab, <i>Petrolisthes armatus</i>, is a highly abundant invader of intertidal oyster reef habitats in Atlantic waters of the southeastern US. Cold water temperatures likely limit the species’ poleward ... -
Free Algebras
In this thesis, we develop a useful framework for studying the free (nonassociative) algebra on a set. This framework will be used to prove several results regarding subalgebras of a free algebra and quotient algebras of ... -
A GEOMETRIC MORPHOMETRIC APPROACH TO IDENTIFY PATTERNS OF TOOTH SHAPE IN EXTANT AND FOSSIL ELASMOBRANCHS
Isolated chondrichthyan teeth are among the most abundant vertebrate fossil represented in the fossil record, and are widely distributed along the southeastern United States. The coastal plain in South Carolina contains ... -
RAPID EVOLUTION OF THERMAL TOLERANCE AND GENOMIC DIVERGENCE DURING THE INVASION OF A PROLIFIC NON-NATIVE RED SEAWEED, Gracilaria vermiculophylla
Biological introductions have rapidly increased during the 20<sup>th</sup> century and can negatively impact recipient communities by homogenizing biodiversity. Commonly, colonization success has been attributed to ...
