Estimating Relative Abundance Of Young-Of-The-Year American Eel, Anguilla Rostrata, In The Virginia Tributaries Of Chesapeake Bay, Spring 2018, Troy D. Tuckey, Mary C. Fabrizio
American Eel (Anguilla rostrata) is a valuable commercial species along the Atlantic coast of North America from New Brunswick to Florida. In the U.S., harvests have declined, with similar patterns occurring in the Canadian Maritime Provinces (Meister and Flagg 1997). An average of 62% of the annual landings of U.S. commercial harvest since 1993 have come from the Chesapeake Bay (personal communication from the National Marine Fisheries Service, Fisheries Statistics Division, 9 February 2015). In 2013, Virginia commercial landings were approximately 100,298 lbs; since mandatory reporting began in 1993, average annual landings in Virginia have been 193 ...
Depth-Dependent Environmental Drivers Of Microbial Plankton Community Structure In The Northern Gulf Of Mexico, 2019 Middle Tennessee State University
Depth-Dependent Environmental Drivers Of Microbial Plankton Community Structure In The Northern Gulf Of Mexico, Cole Easson, Jose Lopez
Biology Faculty Articles
The Gulf of Mexico (GoM) is a dynamic marine ecosystem influenced by multiple natural and anthropogenic processes and inputs, such as the intrusion of warm oligotrophic water via the Loop Current, freshwater and nutrient input by the Mississippi River, and hydrocarbon inputs via natural seeps and industrial spills. Microbial plankton communities are important to pelagic food webs including in the GoM but understanding the drivers of the natural dynamics of these passively distributed microorganisms can be challenging in such a large and heterogeneous system. As part of the DEEPEND consortium, we applied high throughput 16S rRNA sequencing to investigate the ...

Changing Oceanic Conditions On The Foraging Patterns Of Cassin’S Auklets, Ptychoramphus Aleuticuschanging Oceanic Conditions On The Foraging Patterns Of Cassin’S Auklets, Ptychoramphus Aleuticus, Clare Flynn
Pomona Senior Theses
Cassin’s auklet (Ptychoramphus aleuticus) reproductive success has been monitored on Southeast Farallon Island (SEFI) for the past 45 years. Their productivity has varied with oceanic conditions. The purpose of this study is to connect how oceanic conditions affect Cassin’s auklet foraging behaviors. The California Current System (CCS) can normally maintain high plankton productivity, and thus high seabird productivity, because of coastal upwelling. I hypothesized that lower upwelling and/or higher sea surface temperatures (SSTs) lead Cassin’s auklets to spend more time on intensive foraging behaviors such as flying and diving, and have less time to spend resting ...
In The Eye Of The Storm: Houston After Hurricane Harvey, 2019 Claremont Colleges
In The Eye Of The Storm: Houston After Hurricane Harvey, Brandon Tolentino-Serrano
Pomona Senior Theses
Situated in one of the wettest climates in America, Houston, TX has had a long history of heavy rains and unprecedented floods. Unfortunately, floods have become more common over the last few decades as climate change increases the frequency and intensity of hurricanes around the globe. To complicate matters further, Houston has quickly sprawled to accommodate over 2.5 billion people. Rapid urbanization has rendered the landscape even more susceptible to floods through excess concretization and watershed disturbance. This thesis traces the history of the Bayou City in relation to the damages caused by Hurricane Harvey. By mapping out the ...
Living Shoreline Stabilization To Increase Resiliency At De Soto National Memorial, 2018 University of Central Florida
Living Shoreline Stabilization To Increase Resiliency At De Soto National Memorial, Linda Walters, Melinda Donnelly, Christian Pilato, Suzanne Connor
CEELAB Research Data
De Soto National Memorial (Bradenton, FL) is an important location where both Native Americans and De Soto's army of soldiers once lived. We have been working closely with the National Park Service and the University of Central Florida to understand how to best stabilize this shoreline using living shoreline techniques combined with long-term natural recruitment. Stabilizing De Soto's shoreline is essential to decrease erosion and shoreline loss to protect the Park's cultural and natural resources, especially the numerous historically significant shell middens. Through pre-restoration monitoring, we determined that high-energy boat wakes were limiting natural mangrove recruitment. Lack ...
Legacy Habitat Suitability Of Eastern Oysters (Crassostrea Virginica) In Louisiana: A Prelude To Mississippi River Delta Freshwater Diversions, Tasia Mv Denapolis
University of New Orleans Theses and Dissertations
The Louisiana oyster industry is greatly impacted by freshwater and sediment diversions that are part of the effort to restore the state’s coastline. A habitat suitability index (HSI) proposes species-habitat relationships that can be instrumental in creating impact assessments and suitability predictions for management as new diversions are implemented. An oyster (Crassostrea virginica) HSI was developed using three variables crucial to oyster sustainability: average annual salinity, minimum monthly salinity, and average salinity during the spawning season. These Legacy HSI visualizations show annual fluctuations in the distribution of zones suitable for oyster cultivation prior to proposed diversions in Pontchartrain and ...

A Comparison Of Phytoplankton Nutrient Limitation Between The Marsh And Beach Environments Of Waties Island, Sc, 2018 Coastal Carolina University
A Comparison Of Phytoplankton Nutrient Limitation Between The Marsh And Beach Environments Of Waties Island, Sc, Raymond Sgambati, George Boneillo
The aim of this study was to investigate the differences in nutrient limitation within the beach and marsh environments at Waties Island, SC. Conducting the experiment on Waties Island allowed most physical factors to be held as constant, meaning the marsh and beach environments would serve as the only variables. Experiments were performed in the winter, spring, summer and fall of 2018 to determine temporal changes in limitation to phytoplankton and cyanobacteria growth. Nutrient additions included dissolved inorganic nitrogen (nitrate, nitrite, and ammonium), dissolved organic nitrogen (urea), and phosphate. To test for co-limitation, a nitrate & phosphate treatment was also used. Triplicate treatments were incubated for 48 hours in a Thermo Scientific Precision Model 818 Incubator. Changes in phytoplankton and cyanobacteria biomass were determined by monitoring chlorophyll, phycocyanin, and phycoerythrin concentrations fluorometrically. What was found was typical of coastal marine environments in the southeastern United States; that nitrogen is the main ...
Can A Global Fund Help Solve The Global Marine Plastic Debris Problem?, 2018 University of Wollongong
Can A Global Fund Help Solve The Global Marine Plastic Debris Problem?, Karen Raubenheimer, Alistair Mcilgorm
Journal of Ocean and Coastal Economics
The problem of marine plastic debris impacts all of the world’s oceans and requires all nations to respond. However, developing States require funds to improve waste management infrastructure and services in order to reduce marine debris at source. Plastics manufacturers and retailers globally must be incentivised to design products for the environment as well as for the collection and end-of-life treatment facilities available within the intended markets. Given the oceans are a global common, we investigate the option of developing a global fund mechanism to progress the necessary actions to reduce plastic waste entering the world’s oceans. This ...

Peruvian Pinnipeds As Archivists Of Enso Effects, Mickie Rae Edwards
HCNSO Student Theses and Dissertations
Environmental fluctuations in the eastern Pacific Ocean are reflected in the tissues of some of its most vulnerable apex predators, the Peruvian fur seal (PFS) Arctocephalus australis ssp.and the South American sea lion (SASL) Otaria byronia.These large pinnipeds live in sympatry along the Pacific coastline of South America and forage within the neritic waters over the continental shelf. The coastal waters off Peru are a region of great environmental fluctuations due to periodic, oscillating El Niño- La Niña- Southern Oscillation (ENSO) events, which result in ecosystem-wide food web changes. Pinniped vibrissae (whiskers) are continuously growing keratinous tissues and ...
Indirect Effects Of Ocean Warming And Acidification On The Realized Recruitment Of Agaricia Agaricites, 2018 Nova Southeastern University
Indirect Effects Of Ocean Warming And Acidification On The Realized Recruitment Of Agaricia Agaricites, Allan Anderson
HCNSO Student Theses and Dissertations
Over the past few decades, coral cover has declined worldwide due to overfishing, disease, and storms, and these effects have been exacerbated by ocean warming and acidification. Corals are extremely susceptible to these changes because they are already living close to their thermal and aragonite saturation thresholds. Ocean warming and acidification (OAW) may also impact coral survival and growth by impacting their settlement cues. Coral larvae use crustose coralline algae (CCA) and their associated biofilms as cues for settlement, i.e., habitat selection. Settlement cues can also be negatively affected by increased water temperature and acidity. It was hypothesized that ...

OEAS Faculty Publications
The Antarctic silverfish (Pleuragramma antarctica) is a critically important forage species with a circumpolar distribution and is unique among other notothenioid species for its wholly pelagic life cycle. Previous studies have provided mixed evidence of population structure over regional and circumpolar scales. The aim of the present study was to test the recent population hypothesis for Antarctic silverfish, which emphasizes the interplay between life history and hydrography in shaping connectivity. A total of 1067 individuals were collected over 25 years from different locations on a circumpolar scale. Samples were genotyped at fifteen microsatellites to assess population differentiation and genetic structuring ...

Microbiome Diversity Of Coastal Tidal Floodwater In Southeastern Florida, Marissa Wickes
HCNSO Student Theses and Dissertations
Over 3.7 million people are in high risk of coastal flooding and live within 1 mile of high tide in the US alone. The Atlantic coast is one of the most vulnerable areas due to its low elevation, large population, and economic importance (Bray, et. al, 2016). Coastal municipalities in the region of Southeast Florida, such as the cities of Miami, Miami Beach, Fort Lauderdale, etc., are at especial risk from coastal flooding related to sea level rise. The US National Climate Assessment has named Miami, Florida as the economically most vulnerable city impacted by this sea level rise ...
Blue Marlin (Makaira Nigricans) Horizontal Movements In The Western South Atlantic, 2018 Nova Southeastern University
Blue Marlin (Makaira Nigricans) Horizontal Movements In The Western South Atlantic, Eduardo W. Wanick
HCNSO Student Capstones
Blue marlin (Makaira nigricans) have been documented to undertake long – and sometimes transoceanic – migrations, according to electronic pop-up satellite archival tag (PSAT) data obtained primarily in the western North Atlantic, with additional reported deployments from selected locations in the Pacific. Information on the movements of blue marlin in the South Atlantic, however, is lacking, despite evidence of spawning aggregations off the coast of Brazil during the Southern Hemisphere’s late spring and summer. Additionally, there are no reported long-term PSAT tag deployments on blue marlin in the western South Atlantic. Therefore, their movements in that large area remain unknown.
Population Dynamics And Genotypic Richness Of The Threatened Acropora Spp. And Their Hybrid In The U.S. Virgin Islands, 2018 Nova Southeastern University
Population Dynamics And Genotypic Richness Of The Threatened Acropora Spp. And Their Hybrid In The U.S. Virgin Islands, Hannah F. Nylander-Asplin
HCNSO Student Theses and Dissertations
Since the 1980’s, there has been an unprecedented decline in the reef-building Caribbean corals, Acropora cervicornis and A. palmata, which has led to their listing as “threatened” under the U.S Endangered Species Act. Despite this protective status, these Acropora species continue to experience declines primarily attributed to disease, global climate change, and storm damage. Recent evidence suggests the hybrid of these threatened species (A. prolifera) is found at abundances similar to or higher than the parental species at many sites throughout the Caribbean. However, there is still much that is unknown as to how and why hybrids may ...
