Ichthyoplankton Composition In The Loop Current And Sargassum Habitats In The Northern Gulf Of Mexico, Stephanie Morgan Taylor 2015 University of Southern Mississippi

Ichthyoplankton Composition In The Loop Current And Sargassum Habitats In The Northern Gulf Of Mexico, Stephanie Morgan Taylor

Master's Theses

Ichthyoplankton in the Gulf of Mexico (GOM) aggregate in two different habitats that serve to provide refuge and concentrate prey in an otherwise oligotrophic environment: the Loop Current (LC) a mesoscale oceanographic feature characterized by the transition of environmental conditions of the water mass between the GOM and Caribbean; and Sargassum, a two species assemblage of floating brown algae that is habitat for many larval and juvenile obligate and associated fishes. The objectives of this study were to characterize the density and community composition of ichthyoplankton within these habitats using multivariate analysis. I identified three unique assemblages of ichthyoplankton at ...

Monitoring Abundance Of Carcinus Maenas Developmental Stages In Seadrift Lagoon, Andrea M. Fieber 2015 California Polytechnic State University

Monitoring Abundance Of Carcinus Maenas Developmental Stages In Seadrift Lagoon, Andrea M. Fieber

STAR (STEM Teacher and Researcher) Program Posters

Able to tolerate a wide range of habitats, temperatures, and salinities, Carcinus maenas thrives in much of its non-native range, out-competing native crabs for resources while diminishing food supplies for a variety of marine and estuarine organisms. In Seadrift Lagoon, a manmade inlet of Bolinas Lagoon in Marin County, California, green crabs comprise a significant portion of benthic fauna, and trapping efforts began in 2009 to eradicate them. We analyzed several years of trapping data to monitor demographic changes for this closed population, performed larvae and megalopae sampling with pot scrubbers, and counted eggs on ovigerous females captured in Seadrift ...


Analyses Of Indices Of Abundance For Important Groundfish Species In The Northern Gulf Of Mexico From 1987-2009, Relative To Shrimp Bycatch; With Age And Growth Of Three Sciaenid Species, Allison Renee Odom 2015 University of Southern Mississippi

Analyses Of Indices Of Abundance For Important Groundfish Species In The Northern Gulf Of Mexico From 1987-2009, Relative To Shrimp Bycatch; With Age And Growth Of Three Sciaenid Species, Allison Renee Odom

Master's Theses

Bycatch in the shrimp fishery became of particular concern in the 1980s during the peak of shrimp harvest in the northern Gulf of Mexico. Shrimp bycatch is of major importance because the majority of catch in the fishery is not intended target species of commercial shrimp, and most of the additional bycatch is returned to the sea dead or dying, inducing higher rates of mortality. This study was developed to assess the potential ecosystem effects of shrimp harvest on thirty selected species/species groups commonly encountered within the shrimp fishery as bycatch. Delta-lognormal modeling (DLM) was used to determine the ...


Evaluation Of Anthropogenic Marine Debris And Sargassum Fluitans And Its Potential Impact On Sea Turtle Hatchlings At Sandy Point National Wildlife Refuge, Christina MacMillan 2015 JLS Middle School

Evaluation Of Anthropogenic Marine Debris And Sargassum Fluitans And Its Potential Impact On Sea Turtle Hatchlings At Sandy Point National Wildlife Refuge, Christina Macmillan

STAR (STEM Teacher and Researcher) Program Posters

Anthropogenic debris, particularly plastic, has become a significant threat for marine species with the increased use of plastics over the years. Marine birds and sea turtles, mostly green, loggerhead and leatherback turtles, are especially vulnerable to mistaking plastic debris for food and ingesting it. There has been a rise in the incidence of turtles having plastic fragments in their GI tracts; even small amounts of plastic may have major long-term health and reproductive effects. On the nesting beaches, both adults and hatchlings may become entangled in debris or have trouble navigating around beach debris during their crawl to the sea ...


Do Marine Protected Areas Affect Emerging Fisheries Population Density?, Jennifer Greene, Katherine O. Grady, Crow White, Danielle Zacherl 2015 California Polytechnic State University - San Luis Obispo

Do Marine Protected Areas Affect Emerging Fisheries Population Density?, Jennifer Greene, Katherine O. Grady, Crow White, Danielle Zacherl

STAR (STEM Teacher and Researcher) Program Posters

Kellet’s whelk, Kelletia kelletii, were observed at sample sites throughout their range from Baja California, Mexico, to Monterey, CA to determine patterns of population density. Sample sites in each region were either located within California marine protected areas where take of the Kellet’s whelk in prohibited, or in non-protected areas where the whelks can be fished both commercially and recreationally. Kellet’s whelk population density was compared between all MPA and non-MPA sample sites. These mean densities were also found for sites in Santa Barbara and San Diego near active fishing ports and compared to data from the ...


Using High Throughput Genomic Sequencing To Predict Ecological Impacts On Sea Turtle Populations, Lesley Anderson 2015 California Polytechnic State University

Using High Throughput Genomic Sequencing To Predict Ecological Impacts On Sea Turtle Populations, Lesley Anderson

STAR (STEM Teacher and Researcher) Program Posters

Marine turtles are long-lived, migratory vertebrates that encounter a variety of human and natural stressors throughout their lives. Understanding the biology and threats of these animals is challenging because they are hard to observe, and can migrate across whole ocean basins. Minimally invasive sampling techniques (e.g., blood samples) allow us to learn about their physiology, genetics, and the environmental conditions they have experienced. In this project, we developed a novel method to extract the RNA from whole green and loggerhead turtle blood from animals inhabiting a variety of sites across the Pacific Ocean. Some habitats are more pristine, while ...


Time-Series Evaluation Of Suspect Rickettsiales-Like Bacteria Presence In Acropora Cervicornis Off Of Broward County From Years 2001–2012, Steven Di Lauro 2015 Nova Southeastern University

Time-Series Evaluation Of Suspect Rickettsiales-Like Bacteria Presence In Acropora Cervicornis Off Of Broward County From Years 2001–2012, Steven Di Lauro

Theses and Dissertations

Rickettsiales-like organisms (RLOs) are thought to be related to bacteria in the order Rickettsiales. They have been reported to occur in the staghorn coral (Acropora cervicornis), and this study investigated trends of infection over time, and in relation to the health of infected corals. This study focuses on tissue samples taken mostly from visibly healthy A. cervicornis thickets in Broward County, Florida, and processed for histological examination. Samples were originally collected and analyzed to document reproduction during years 2001 through 2012, and tissue loss diseases (white-band disease [WBD] types I and II, and rapid tissue loss). The presence of ...


Possible Stock Structure Of Coastal Bottlenose Dolphins Off Baja California And California Revealed By Photo-Identification Research, Richard H. Defran, Marthajane Caldwell, Eduardo Morteo, Aimée Lang, Megan Rice, David Weller 2015 San Diego State University

Possible Stock Structure Of Coastal Bottlenose Dolphins Off Baja California And California Revealed By Photo-Identification Research, Richard H. Defran, Marthajane Caldwell, Eduardo Morteo, Aimée Lang, Megan Rice, David Weller

Bulletin of the Southern California Academy of Sciences

Boat-based photo-identification research has been carried out on bottlenose dolphins in the eastern North Pacific coastal waters of northern Baja California, Mexico and southern and central California, USA from 1981 to 2001. Within these waters, bottlenose dolphins routinely travel back and forth between coastal locations while generally staying within a narrow coastal corridor of about 1 km or less from the shore. Inter-area match rates between 616 dolphins photo-identified in Ensenada, San Diego, Orange County and Santa Barbara between 1981-2000 averaged 76%. To explore possible southern range limits for these California coastal dolphins, photo-identification surveys were carried out in the ...


Identical Response Of Caged Rock Crabs (Genera Metacarcinus And Cancer) To Energized And Unenergized Undersea Power Cables In Southern California, Usa, Milton S. Love, Mary M. Nishimoto, Scott Clark, Ann Scarborough Bull 2015 University of California, Santa Barbara

Identical Response Of Caged Rock Crabs (Genera Metacarcinus And Cancer) To Energized And Unenergized Undersea Power Cables In Southern California, Usa, Milton S. Love, Mary M. Nishimoto, Scott Clark, Ann Scarborough Bull

Bulletin of the Southern California Academy of Sciences

Energy generation facilities (i.e., wave and wind) are being sited in offshore marine waters. The electricity generated from these facilities is transmitted to shore through cables carrying alternating or direct current. This current produces an electromagnetic field (EMF) that is emitted from the cable. Concerns have been voiced regarding how marine organisms, in this instance crabs, respond to the EMF emitted by submarine power cables. Two submarine cables, one energized and the other unenergized, and separated by about 7 m, were used in the experiment. Crabs (Metacarcinus anthonyi (Rathbun, 1897) and Cancer productus (Randall, 1839)) were placed in plastic ...

Connectivity Of Reef Fishes Between Mangroves And Coral Reefs In Broward County, Florida, Jennifer Savaro 2015 Nova Southeastern University

Connectivity Of Reef Fishes Between Mangroves And Coral Reefs In Broward County, Florida, Jennifer Savaro

Theses and Dissertations

Many marine fishes use the mangrove ecosystem for foraging, protection, spawning, and as a nursery habitat. To develop a better understanding of energy flow between the coastal mangrove and coral reef ecosystems, the ontogentic migration and trophic connectivity of reef fishes were examined through the use of carbon (C), nitrogen (N), and oxygen (O) stable isotope ratios. Juvenile and adult gray snapper Lutjanus griseus, lane snapper L. synagris, bluestriped grunt Haemulon sciurus, French grunt H. flavolineatum, sailor’s choice H. parra, yellowfin mojarra Gerres cinereus, and great barracuda Sphyraena barracuda were collected from both mangrove and coral reef sites located ...


Staghorn Coral, Acropora Cervicornis, Restoration In South Florida: Growth And Survivorship Of Outplanted Nursery Corals, Meaghan Johnson 2015 Nova Southeastern University

Staghorn Coral, Acropora Cervicornis, Restoration In South Florida: Growth And Survivorship Of Outplanted Nursery Corals, Meaghan Johnson

Theses and Dissertations

This thesis provides a detailed analysis of the growth and survivorship of outplanted Acropora cervicornis corals from underwater nurseries within three regions of the Florida Reef Tract. Substantial loss of stony coral cover on Florida’s coral reefs, including the branching staghorn coral, Acropora cervicornis, has occurred for decades due to disturbances such as disease, temperature induced bleaching, hurricanes, sedimentation, and pollution. This rapid population decline contributed to A. cervicornis being listed as a threatened species under the U.S. Endangered Species Act in May 2006. To aid in the recovery of the species, coral fragments were grown in underwater ...

Long-distance movements of animals are an important driver of population spatial dynamics and determine the extent of overlap with area-focused human activities, such as fishing. Despite global concerns of declining shark populations, a major limitation in assessments of population trends or spatial management options is the lack of information on their long-term migratory behaviour. For a large marine predator, the tiger shark Galeocerdo cuvier, we show from individuals satellitetracked for multiple years (up to 1101 days) that adult males undertake annually repeated, roundtrip migrations of over 7,500km in the northwest Atlantic. Notably, these migrations occurred between the highly disparate ...
