Gulf Sturgeon (Acipenser Oxyrinchus Desotoi) Pre-Restoration Occupancy Patterns On Ship Island, Mississippi Sound With An Evaluation Of Designated Critical Habitat Use By Eastern And Western Population Segments, Page Elizabeth Vick
Critical spawning and feeding habitat was designated for federally threatened, anadromous Gulf Sturgeon (GS) to aid in population recovery. This study examined GS occupancy, habitat use, and movement through critical habitat monitored by the Ship Island (SI) acoustic array during overwintering periods from 2011 to 2015 prior to MsCIP SI restoration. An occupancy index analyzed patterns of spatial and temporal habitat use of both western and eastern population segments (WPS and EPS, respectively) of GS on the SI array. The ends of SI along with the passes and cuts of the island, especially Dog Keys Pass (DKP), were occupied by ...

Evaluation Of Methods To Enhance Reef Restoration, David S. Gilliam, Alison L. Moulding, Vladimir N. Kosmynin, Vanessa I. P. Brinkhuis, Richard E. Dodge
The coral reefs of southeast Florida are offshore a highly urbanized area with a population exceeding 5 million people and three major shipping ports with over 6000 ships calling on an annual basis. Reef injury events are common and have been caused by ship groundings and marine construction activities such as channel dredging and cable placement. Restoration activities generally only include the reattachment of dislodged stony corals, removal of rubble, and boulder stabilization. The Florida Department of Environmental Protection has recognized these limited activities and is collaborating with Nova Southeastern University’s Oceanographic Center to study ways to accelerate coral ...
Coral Of Opportunity Survivorship And The Use Of Coral Nurseries In Coral Reef Restoration, 2016 Nova Southeastern University Oceanographic Center
Coral Of Opportunity Survivorship And The Use Of Coral Nurseries In Coral Reef Restoration, Jamie A. Monty, David S. Gilliam, Kenneth Banks, David K. Stout, Richard E. Dodge
Coral reef damage is unfortunately becoming a common occurrence off southeast Florida, U.S.A. Reattachment of the dislodged scleractinian corals usually initiates damage site restoration. Because mortality of dislodged colonies is typically high and natural recovery in southeast Florida is typically slow, transplantation of additional scleractinian corals into a damaged area has been used to accelerate reef recovery. Donor colonies available for transplantation have been grown in situ, grown in laboratories, and taken from nondamaged reef areas. An alternative source of donor colonies for transplantation into damaged sites is “corals of opportunity,” which we define as scleractinian corals that ...
Determining The Extent And Characterizing Coral Reef Habitats Of The Northern Latitudes Of The Florida Reef Tract (Martin County), 2016 Nova Southeastern University Oceanographic Center
Determining The Extent And Characterizing Coral Reef Habitats Of The Northern Latitudes Of The Florida Reef Tract (Martin County), Brian K. Walker, David S. Gilliam
Climate change has recently been implicated in poleward shifts of many tropical species including corals; thus attention focused on higher-latitude coral communities is warranted to investigate possible range expansions and ecosystem shifts due to global warming. As the northern extension of the Florida Reef Tract (FRT), the third-largest barrier reef ecosystem in the world, southeast Florida (25–27° N latitude) is a prime region to study such effects. Most of the shallow-water FRT benthic habitats have been mapped, however minimal data and limited knowledge exist about the coral reef communities of its northernmost reaches off Martin County. First benthic habitat ...
Dredging And Shipping Impacts On Southeast Florida Coral Reefs, 2016 Nova Southeastern University Oceanographic Center
Dredging And Shipping Impacts On Southeast Florida Coral Reefs, Brian K. Walker, David S. Gilliam, Richard E. Dodge, Joanna Walczak
Many coastal regions have experienced extensive population growth during the last century. Commonly, this growth has led to port development and expansion as well as increased vessel activity which can have detrimental effects on coral reef ecosystems. In southeast Florida, three major ports built in the late 1920’s along 112 km of coastline occur in close proximity to a shallow coral reef ecosystem. Recent habitat mapping data were analyzed in GIS to quantify the type and area of coral reef habitats impacted by port and shipping activities. Impact areas were adjusted by impact severity: 100% of dredge and burial ...

Background: The rising temperature of the world’s oceans has become a major threat to coral reefs globally as the severity and frequency of mass coral bleaching and mortality events increase. In 2005, high ocean temperatures in the tropical Atlantic and Caribbean resulted in the most severe bleaching event ever recorded in the basin.
Methodology/Principal Findings: Satellite-based tools provided warnings for coral reef managers and scientists, guiding both the timing and location of researchers’ field observations as anomalously warm conditions developed and spread across the greater Caribbean region from June to October 2005. Field surveys of bleaching and mortality ...
Analysis Of Factors Influencing Southeast Florida Coral Reef Community Composition, 2016 National Coral Reef Institute, Nova Southeastern University Oceanographic Center
Analysis Of Factors Influencing Southeast Florida Coral Reef Community Composition, M. A. Phillips, David S. Gilliam, L. K. B. Jordan, Richard E. Dodge, Louis E. Fisher
The southeast Florida reef system lies offshore a heavily populated and urbanized coast. These high latitude reefs are not only affected by their geography but also by anthropogenic factors that accompany an urban area such as dredging activities, ship groundings, waste water outfalls, runoff and beach erosion. Sedimentation has been shown to influence stony coral community composition including dominance, abundance, cover, diversity, and colony size. Using annual monitoring data collected since 2000, the southeastern Florida reef community is being analyzed to examine if and how sedimentation and other factors such as depth, distance from shore and distance from port channels ...

Significant coral reef community development along the eastern shelf of the United States continues northward of the Florida Keys through Miami-Dade, Broward, Palm Beach, and Martin Counties, Florida (to Latitude 27° N). These Southeast Florida high-latitude coral communities have approximately 30 species of stony corals, stony coral coverage of 2-3%, and a diverse assemblage of reef gorgonians, sponges, and fishes. This system lays within 3 km of the coast offshore a highly urbanized area comprising a population of over 5 million people (the population of Broward County alone exceeds 1.7 million). These reefs are important economic assets: a 2001 ...
An Experimental Histopathological Rating Scale Of Sedimentation Stress In The Caribbean Coral Montastraea Cavernosa, 2016 Nova Southeastern University, Oceanographic Center
An Experimental Histopathological Rating Scale Of Sedimentation Stress In The Caribbean Coral Montastraea Cavernosa, Bernardo Vargas-Ángel, Bernhard Riegl, David S. Gilliam, Richard E. Dodge
Colonies of Montastraea cavernosa were exposed to daily applications of approx. 200–225 mg cm– 2 sediments, during a four-week period, in order to investigate coral responses to increased sedimentation. Effects were assessed based on the histopathological condition of specimen tissues. Mild stress responses were noted as early as week one, including tissue swelling and polyp retraction, as well as changes in size and appearance of mucous secretory cells. As stress progressed, further inflammation of the mucous secretory cells was observed. Severe effects were observed in weeks 3 and 4, including atrophy of the outer epidermis, increased granularity and debris ...

Artificial Substrate And Coral Reef Restoration: What Do We Need To Know To Know What We Need, 2016 Nova Southeastern University Oceanographic Center
Artificial Substrate And Coral Reef Restoration: What Do We Need To Know To Know What We Need, Richard E. Spieler, David S. Gilliam, Robin L. Sherman
To use artificial substrate effectively in coral reef restoration certain basic knowledge is required: (1) what is the artificial substrate expected to accomplish relative to the goals of the restoration effort and (2) what are the expected interactions of the selected substrate’s composition, texture, orientation, and design with the damaged environment and the biota of interest. Whereas the first point is usually clear, at least in general terms, the second is not. In this review, we examine: the functions of artificial substrate in restoration and some of the physical (i.e., composition; surface texture; color and chemistry; and design ...
Acoustic Remote-Sensing Of Reef Benthos In Broward County, Florida (Usa), 2016 Nova Southeastern University Oceanographic Center
Acoustic Remote-Sensing Of Reef Benthos In Broward County, Florida (Usa), Ryan P. Moyer, Bernhard Riegl, Richard E. Dodge, Brian K. Walker, David S. Gilliam
Benthic assemblages of variable density cover three progressively deeper ridges that parallel the Broward County, Florida, coast. An acoustic bottom classification survey using QTCView5 with a 50 kHz transducer showed different acoustic classes on the shallow reef-ridge and the two deeper reef-lines, which both showed the same acoustic signature. Ground-truthing showed that the differences in acoustic signature corresponded to different benthic assemblages: nearshore hardgrounds had low live cover and were dominated by algae covering substrate, the two deeper reef-ridges had the same acoustic signature and similar benthic assemblages (dominated by sponges and gorgonians). The QTCView5 was also able to differentiate ...
A Tale Of Germs, Storms, And Bombs: Geomorphology And Coral Assemblage Structure At Vieques (Puerto Rico) Compared To St. Croix (U.S. Virgin Islands), 2016 National Coral Reef Institute, Nova Southeastern University Oceanographic Center
A Tale Of Germs, Storms, And Bombs: Geomorphology And Coral Assemblage Structure At Vieques (Puerto Rico) Compared To St. Croix (U.S. Virgin Islands), Bernhard Riegl, Ryan P. Moyer, Brian K. Walker, Kevin E. Kohler, David S. Gilliam, Richard E. Dodge
The former U.S. Navy range at Vieques Island (Puerto Rico, United States) is now the largest national wildlife refuge in the Caribbean. We investigated the geomorphology and benthic assemblage structure to understand the status of the coral reefs. Coral assemblages were quantified at 24 sites at Vieques and at 6 sites at St. Croix, U.S. Virgin Islands. These sites were chosen to represent the major zones of reef geomorphology. Sites consisted of two or three 21-m-long photo-quadrate belt transects. The results revealed surprisingly little differentiation in the coral assemblages within and between reefs of comparable geomorphological and oceanographic ...
Vision And Bioluminescence In Deep-Sea Crustaceans, 2016 Nova Southeastern University
Vision And Bioluminescence In Deep-Sea Crustaceans, Tamara Frank
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 ...
Vision And Bioluminescence In The Deep-Sea Benthos, 2016 Nova Southeastern University
Vision And Bioluminescence In The Deep-Sea Benthos, Tamara M. Frank, Sonke Johnsen, Heather D. Bracken-Grissom, Charles Messing, Edith A. Widder
During a NOAA-OER funded research cruise, novel collecting techniques were used to collect live, deep-sea benthic animals for studies of bioluminescence and vision. True color images and emission spectra of bioluminescence were obtained from a number of species, including the spiral octocoral Iridogorgia sp., the sea fan Chrysogorgia sp., the sea pen Umbellula sp., and the caridean shrimp Heterocarpusoryx. Electrophysiological studies were conducted on 3 species of decapod crustaceans collected with methods that limited light damage to their photoreceptors. The caridean shrimp, Bathypalaemonella, collected from 1920m, was always found in association with the bioluminescent spiral octocoral Iridogorgia. While moribund at ...
Light And Vision In The Deep-Sea Benthos: I. Bioluminescence At 500-1000 M Depth In The Bahamian Islands, Sönke Johnsen, Tamara M. Frank, Steven H.D. Haddock, Edith A. Widder, Charles Messing
Bioluminescence is common and well studied in mesopelagic species. However, the extent of bioluminescence in benthic sites of similar depths is far less studied, although the relatively large eyes of benthic fish, crustaceans and cephalopods at bathyal depths suggest the presence of significant biogenic light. Using the Johnson-Sea-Link submersible, we collected numerous species of cnidarians, echinoderms, crustaceans, cephalopods and sponges, as well as one annelid from three sites in the northern Bahamas (500–1000 m depth). Using mechanical and chemical stimulation, we tested the collected species for light emission, and photographed and measured the spectra of the emitted light. In ...
