Community Structure And Production Of The Macrobenthos On Four Artificial Reefs In The Mississippi Sound In Relation To Substrate And Profile Type, Patrick Daniel Gillam 2016 University of Southern Mississippi

Community Structure And Production Of The Macrobenthos On Four Artificial Reefs In The Mississippi Sound In Relation To Substrate And Profile Type, Patrick Daniel Gillam

Master's Theses

In recent years, the Mississippi Department of Marine Resources (DMR) has made a concerted effort to enhance its coastal fishery resources by creating artificial reefs. Through this effort, 73 nearshore reefs have been created across the MS coast. Different substrate types used to construct MS artificial reefs include oyster shell and cement rubble. Two types of reef architecture used include high profile breakwater and low profile submerged structures. This study compared the benthic biota associated with oyster shell and cement rubble substrates among four artificial reefs representing high and low profile structures in summer 2011. Colonized benthic biota were quantified ...

The Shellfish Corner: Aquaculture Of Exotic Shellfish Species, Michael A. Rice 2016 University of Rhode Island

The Shellfish Corner: Aquaculture Of Exotic Shellfish Species, Michael A. Rice

Michael A Rice

Successful commercial aquaculture operations have grown in the Pacific Northwest and the Canadian West Coast on two exotic species Crassostrea gigas and Tapes philippinarum introduced from Japan during the 20th Century. Introduction of the Asian oyster C. ariakensis was proposed as a means for recovering distressed oyster fisheries in Chesapeake Bay, but it was not pursued after extensive public review deemed the practice too risky. However due to increased global shipping, exotic bivalves are being transferred worldwide. The recent introduction of a Western Hemisphere mussel Mytella charruana into the Philippines provides a good case study of shellfish aquaculture industry opportunities ...


Abundance And Diversity Of Deep-Sea Crustaceans Of Bear Seamount, New England Seamount Chain, Valerie Miranda 2016 Nova Southeastern University

Abundance And Diversity Of Deep-Sea Crustaceans Of Bear Seamount, New England Seamount Chain, Valerie Miranda

HCNSO Ocean Science Jamboree

Bear Seamount (39° 55’ N; 67° 30’ W) is the westernmost peak of extinct undersea volcanoes in the New England Seamount Chain (Moore et al., 2003). It is located on the continental slope off Georges Bank, and is governed by unique environmental factors and currents that may be unlike those of the other seamounts (Moore et al., 2003). Previous cruises to this seamount have been successful in capturing abundant fishes, cephalopods and invertebrates (Moore et al., 2003; Moore et al., 2004; Moore et al., 2008), but only the distribution patterns of the fishes and cephalopods have been examined, leaving a ...


Vision And Bioluminescence In Deep-Sea Crustaceans, Tamara Frank 2016 Nova Southeastern University

Vision And Bioluminescence In Deep-Sea Crustaceans, Tamara Frank

HCNSO Ocean Science Jamboree

Adaptations of the visual systems of deep-sea crustaceans to dim light environments are driven not only by environmental light, but also biologically produced light, or bioluminescence. In the pelagic zone, the relationship is driven, at least in part, by intrinsic bioluminescence. The unusual possession of UV sensitivity, in additional to the expected blue sensitivity, in several species of deep-sea crustaceans appears to be linked to their two modes of bioluminescence. In the benthic zone, the relationship is not so clear. On several NOAA-OER funded research expeditions, electrophysiological studies were conducted on a number of species of decapod crustaceans collected with ...


Monitoring A Problem: Evaluating The Ecological Status Of The Invasive Nile Monitor In Florida And Forecasting Population Expansion Using Computational Gis, Noah Cohen 2016 Nova Southeastern University

Monitoring A Problem: Evaluating The Ecological Status Of The Invasive Nile Monitor In Florida And Forecasting Population Expansion Using Computational Gis, Noah Cohen

HCNSO Ocean Science Jamboree

The state of Florida is an epicenter for the introduction of exotic terrestrial and marine species, often which are attributed to the pet industry. Identifying the threats posed by exotics that may become invasive is critical to manage and protect indigenous species and habitats. One such exotic that is now invasive in Florida is the Nile Monitor (Varanus niloticus). The Nile monitor is a large, predatory lizard native to central and southern Africa that is thought to have been introduced to Florida via both intentional and unintentional releases associated with the exotic pet trade. Since their introduction, Nile monitors have ...


Genomic Assembly Analyses Of Asian Teleost Species Seabass (Lates Calcarifer) And Arowana (Scleropages Formosus), Stephen O'Brien 2016 Nova Southeastern University

Genomic Assembly Analyses Of Asian Teleost Species Seabass (Lates Calcarifer) And Arowana (Scleropages Formosus), Stephen O'Brien

HCNSO Ocean Science Jamboree

The genome assembly and annotation of Asian seabass (Lates calcarifer) , a marine teleost with aquaculture relevance will be described, an initiative of Genome 10K . Though > 500 eukaryotic genome sequences are available in public repositories, the majority are highly fragmented with incomplete assemblies, so considerable effort and resources are often spent to improve their quality. In the present study, PacBio long read sequencing , genetic and optical mapping, and syntenic inference were combined to build a chromosome-length assembly with a contig N50 size over 1 Mb and scaffold N50 size over 25 Mb that span ~90% of the genome was achieved.

If You Build It, Will They Come? Exploring Enhancements To Artificial Structure For Use In Restoration And Mitigation Applications In The Mexican Caribbean, Kirk Kilfoyle 2016 Nova Southeastern University

If You Build It, Will They Come? Exploring Enhancements To Artificial Structure For Use In Restoration And Mitigation Applications In The Mexican Caribbean, Kirk Kilfoyle

HCNSO Ocean Science Jamboree

A study involving standardized artificial reef modules (ReefballsTM) was conducted in Puerto Morelos, Mexico. The purpose was to explore the use of artificial structure in restoration and mitigation projects in a Caribbean coral reef environment similar to South Florida by applying select experimental treatments hypothesized to accelerate their acquisition of a natural coral reef assemblage. Multiple hypotheses on the progression and interaction between artificial structure and the resulting fish, coral, algal, and non-coral invertebrate assemblages were examined. Each of 40 reefball modules received one of 4 treatments (10 modules/treatment): invertebrate substrate pads, coral transplants, settlement plates, or control. Following ...


An Alternate Trawling Method: Reduced Bycatch And Benthic Disturbance Achieved With The Wing Trawling System, Geoffrey Udoff 2016 University of New Orleans

An Alternate Trawling Method: Reduced Bycatch And Benthic Disturbance Achieved With The Wing Trawling System, Geoffrey Udoff

University of New Orleans Theses and Dissertations

The Wing Trawling System (WTS) was tested as an alternative to traditional shrimp capture methods in the Gulf. Compared to an otter trawl, this trawl was conceived to reduce bycatch, retain shrimp catch, and minimize seafloor disturbance. Through seventy-one paired tows, the WTS was assessed against a standard otter trawl. The WTS was found to reduce bycatch by 63-65% and reduce shrimp catch by 30-35%. Additionally, I measured the depth of the scars produced by both trawls and quantified the turbidity of the plumes behind them. The scars left by the WTS and the otter trawl were between 9.9 ...


Connecting The Physiological And Behavioral Response To Heat Stress On A Warming Planet, Anastasia Kalyta 2016 Chapman University

Connecting The Physiological And Behavioral Response To Heat Stress On A Warming Planet, Anastasia Kalyta

Student Research Day Abstracts and Posters

Intertidal communities are considered good models of the biological effects of climate change on ecosystems, as their resident organisms are subjected to heat spells during daytime low tides. The increasing heat exposure can elicit behavioral as well as physiological responses in intertidal organisms. We studied the relationship between these responses to heat stress in the blue-banded hermit crab, Pagurus samuelis, by inducing a “heat shock” with elevated water temperature of 29 °C for 2.5 h. The behavioral effect of heat-shock was quantified using a 30-minute feeding assay, measuring the mass of a standard squid pellet consumed by individual hermit ...


Ocean Acidification And Predator-Prey Relations: Correlating Disruption Of Predator Avoidance With Chemosensory Deficits, Alexandra FW Sidun 2016 Chapman University

Ocean Acidification And Predator-Prey Relations: Correlating Disruption Of Predator Avoidance With Chemosensory Deficits, Alexandra Fw Sidun

Student Research Day Abstracts and Posters

One of the most destructive effects of global climate change is the increased carbon sequestering and consequential acidification of our world’s oceans. The impacts of ocean acidification on marine organisms are still relatively unknown, especially effects on behavioral ecology. Avoiding predation has emerged from recent behavioral ecology literature as a critical feature in the life history of a wide array of animal species; experiments on marine fishes suggest acidic water compromises their predator-avoidance abilities. Recent assays in our lab suggest predator-induced behavior is reduced by weakly acidic water. These experiments do not address the potential factor of generalized malaise ...


Bioavailability Of Dissolved Organic Matter In The North Inlet Estuary, Andrew Mason Gaines Banks 2016 University of South Carolina - Columbia

Bioavailability Of Dissolved Organic Matter In The North Inlet Estuary, Andrew Mason Gaines Banks

Theses and Dissertations

Dissolved organic matter (DOM) is an important source of carbon and energy for microbial food webs in estuaries. The export of DOM from estuaries to the coastal ocean influences shelf productivity and biogeochemical cycles. Chromophoric dissolved organic matter (CDOM) is an important component of the DOM pool that absorbs light, and is photoreactive. There are various optical properties of CDOM that can be used to indicate the sources of DOM, such as whether or not it is derived from terrestrial or marine environments. In this study, the sources and bioavailability of DOM were characterized in the North Inlet estuary near ...


A Comparative Study Of Isolation In Headwater Fishes, Bjorn Victor Schmidt 2016 University of Southern Mississippi

A Comparative Study Of Isolation In Headwater Fishes, Bjorn Victor Schmidt

Dissertations

Headwater resident fishes may be prone to a high rate of population fragmentation within river networks because large streams have habitat conditions outside of their preferred ecological niche and may limit gene flow in the dendritic ecological network. To investigate patterns of population structure, asymmetrical gene flow, and influences on genetic distance and isolation from connecting habitat pathways, species specific ecological traits, and basin scale characteristics, a multi-species, multi-regional study was performed. Six headwater species of fish from four taxonomic groupings were sampled for genetic material in three regions of paired neighbor drainages and then genotyped for eight microsatellite loci ...


Examining The Effectiveness Of Coral Restoration Nurseries, Grace Hanson 2016 University of Rhode Island

Examining The Effectiveness Of Coral Restoration Nurseries, Grace Hanson

Senior Honors Projects

Numerous ecosystems throughout the world are declining and facing conservation challenges. A variety of techniques have been developed in response with active restoration being one of them. Active restoration usually involves planting vegetation in order to restore the area to its previous state. It has been used in multiple ecosystems including seagrasses, forests, and salt marshes. Coral reefs have experienced severe declines worldwide and active restoration has been utilized to help combat their decline. It is generally done by collecting healthy fragments of coral and either transplanting them directly to a declining reef or placing them on a nursery allowing ...
