Distribution And Trophic Ecology Of Bathylagus Euryops (Teleostei: Microstomatidae) Along The Northern Mid-Atlantic Ridge, Christopher J. Sweetman, Tracey Sutton
Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures
The distribution and trophic ecology of many deepwater fishes in the North Atlantic are well documented, particularly for commercially important species. However, few studies based on large-scale latitudinal and vertical gradients have been performed. In June 2004, the MAR-ECO (Census of Marine Life) research expedition aboard the R/V G.O. Sars sampled the deep-pelagic fauna over the northern Mid-Atlantic Ridge with the objective of quantitatively assessing the nekton associated with the ridge from Iceland to the Azores. Catch data revealed Bathylagus euryops to be the biomass dominant species and ranked 3rd in total abundance. Generally considered to be a relatively stable …

Vertical Distribution Of Deep-Pelagic (0-3000 M) Fishes Over The Charlie-Gibbs Fracture Zone Region Of The Northern Mid-Atlantic Ridge, April B. Cook, Tracey Sutton, John K. Galbraith, M. Vecchione
Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures
Only a tiny fraction of the world’s largest volume of living space, the ocean’s midwater biome, has ever been sampled. As part of the International Census of Marine Life field project, MAR-ECO, a discrete-depth trawling survey was conducted in 2009 aboard the NOAA ship Henry B. Bigelow to examine pelagic assemblage structure and distribution over the Charlie-Gibbs Fracture Zone of the northern Mid-Atlantic Ridge. The bottom topography in this region ranges from 4500 m in the channel to 700-800 m on top of adjacent seamounts. Sampling was conducted at 11 stations from 0-3000 m using a Norwegian “Krill” trawl with …

Transcriptomic studies of marine organisms are still in their infancy. A partial, subtracted expressed sequence tag (EST) library of the Caribbean octocoral Erythropodium caribaeorum and the sea fan Gorgonia ventalina has been analyzed in order to find novel genes or differences in gene expression related to potential secondary metabolite production or symbioses. This approach entails enrichment for potential non-"housekeeping" genes using the suppression subtractive hybridization (SSH) polymerase chain reaction (PCR) method. More than 500 expressed sequence tags (ESTs) were generated after cloning SSH products, which yielded at least 53 orthologous groups of proteins (COGs) and Pfam clusters, including transcription factors …

Functional Activation Of Cartilaginous Fish Melanocortin Receptors,
2011
University of Denver
Functional Activation Of Cartilaginous Fish Melanocortin Receptors, Christina Lee Reinick
Electronic Theses and Dissertations
The evolution of the melanocortin receptor (MCR) gene family has been dictated by two genome duplication events (2R hypothesis). The gnathostomes are thus predicted to possess a minimum of four MCR genes. Previous studies on cartilaginous fish have shown evidence for the presence of only three MCRs. The purpose of this thesis is to functionally express the MC5R from the spiny dogfish (Squalus acanthias) and the putative MC2R and MC3R from the elephant shark (Callorhinchus milii); these receptors have not yet been fully characterized. In this study, SacMC5R was able to be expressed in CHO cells …

Pelagic seabirds are highly mobile, reducing the likelihood of allopatric speciation where disruption of gene flow between populations is caused by physically insurmountable, extrinsic barriers. Spatial segregation during the non-breeding season appears to provide an intrinsic barrier to gene flow among seabird populations that otherwise occupy nearby or overlapping regions during breeding, but how this is achieved remains unclear. Here we show that the two genetically distinct populations of Cook's petrel (Pterodroma cookii) exhibit transequatorial separation of non-breeding ranges at contemporary (ca. 2–3 yrs) and historical (ca. 100 yrs) time scales. Segregation during the non-breeding season per se appears as …

Sailfish Habitat Utilization And Vertical Movements In The Southern Gulf Of Mexico And Florida Straits, David W. Kerstetter, Shannon Michael Bayse, Jenny Fenton, John E. Graves
Marine & Environmental Sciences Faculty Articles
Pop-up satellite archival tags (PSATs) were deployed on 19 sailfish Istiophorus platypterus captured in the southern Gulf of Mexico and Florida Straits between 2005 and 2007 on commercial pelagic longline gear (n = 18) and recreational rod-and-reel gear (n = 1). The data from three tags indicated mortality events and were excluded from subsequent analyses. All PSATs were programmed to collect pressure (depth), temperature, and light-level data for 10 d at approximately 90-s intervals. These transmitted point data subsequently allowed the reconstruction of vertical movement patterns. The remaining 16 PSAT data sets indicate that sailfish are primarily associated …

Ecological Design Of Marine Construction For Socio-Economic Benefits: Ecosystem Integration Of A Pipeline In Coral Reef Area, Sylvain Pioch, Philippe Saussola, Kirk Kilfoyle, Richard E. Spieler
Marine & Environmental Sciences Faculty Articles
It is critical to understand that an ecosystem integration of construction requires a close Engineering/Biology partnership to meet socio-economic benefits in management goals. Biologists are not typically trained or licensed for the requisite engineering involved in construction. Likewise, non-biologists designing habitat often can lead to egregious results. For example, unintentionally constructing the wrong habitat, i.e., refuge for predators in a nursery area, or habitat that facilitates the spread of non-desirable species can increase, rather than ameliorate, the impact of construction. In recent years, Pioch and co-workers (unpublished) developed an alternative to the “classic” engineering approach to marine construction. This new …

Angler Survey Of The Connecticut River, Justin P. Davis
EEB Articles
The Connecticut River is the largest and most diverse inland fishery resource in the State of Connecticut. Significant improvements in water quality over the past 30 years have led to progressive increases in recreational use, presumably increasing fishing pressure on some species and possibly decreasing overall fishing quality. To address this concern, the Inland Fisheries Division (IFD) of the Connecticut Department of Energy and Environmental Protection (CT DEEP) conducted an angler survey on the entire portion of the Connecticut River within the state during March-October of 2008-09. The survey used a similar design as a smaller-scale survey of the river’s …

Cell Cycle Regulation In The Florida Red Tide Dinoflagellate, Karenia Brevis, Stephanie Alexandra Brunelle
MUSC Theses and Dissertations
The dinoflagellate, Karenia brevis, produces harmful algal blooms in the Gulf of Mexico that cause extensive marine animal mortalities and human illness nearly annually. The molecular mechanisms controlling cell cycle entry in this dinoflagellate are important because bloom development occurs through asexual cell division. The cell cycle of K. brevis is phased to the diel cycle such that any cells entering the cell cycle on a given day do so synchronously. However, a microarray study of gene expression over a diel/cell cycle found no change in cell cycle transcript levels in actively dividing populations, including genes that code for replication …

The 2011-2012 sampling of Acropora corals, other coral reef benthic invertebrates, and marine debris in the Florida Keys National Marine Sanctuary (FKNMS) is being undertaken as a spatially intensive effort to provide updated population distribution and abundance information. The particular focus of surveys in the Florida Keys, as well as in the U.S. Caribbean (Puerto Rico and the U.S.V.I.), concerns the habitat distribution, colony density, size, condition, and population abundance of Acropora corals. Surveys in the Florida Keys also include assessments of urchins, mollusks, anemones, corallimorpharians, and marine debris. These additional assessments are relatively fast and easy to perform. Annual …

Swimming animals may experience significant changes in the Reynolds number (Re) of their surrounding fluid flows throughout ontogeny. Many medusae experience Re environments with significant viscous forces as small juveniles but inertially dominated Re environments as adults. These different environments may affect their propulsive strategies. In particular, rowing, a propulsive strategy with ecological advantages for large adults, may be constrained by viscosity for small juvenile medusae. We examined changes in the bell morphology and swimming kinematics of the limnomedusa Liriope tetraphylla at different stages of development. L. tetraphylla maintained an oblate bell (fineness ratio _ 0.5–0.6), large velar …

Anaerobic Oxidation Of Methane And The Stoichiometry Of Remineralization Processes In Continental Margin Sediments, David J. Burdige, Tomoko Kamada
OES Faculty Publications
In many coastal and continental margin sediments, pore-water property-property plots yield values of rc:s, the stoichiometric ratio of dissolved inorganic carbon (DIC) produced to sulfate reduced, that are lower than the commonly assumed value of 2. Remineralization of organic matter more reduced than CH2O can cause such observations, as can DIC loss due to authigenic carbonate precipitation. However, through studies of Santa Monica Basin sediments, we have observed that these observations could also be related to the occurrence of anaerobic oxidation of methane (AOM) in sediments. Specifically, using a reactive transport sediment model, we have shown …

The meso- and bathypelagic ocean comprises the largest habitat on earth, yet we know very little about the distribution and activity of protists in this environment. These small eukaryotes are responsible for controlling bacterial abundance in the surface ocean and are major players in the material and energy transfer of pelagic food webs. In this paper, we quantify microbial eukaryotes in the deep North Atlantic, as well as provide a basic characterization of eukaryote community changes through the water column. To this end, we counted organisms using 2 different approaches: (1) catalyzed reporter deposition fluorescence in situ hybridization (CARD-FISH, also …

Diel vertical migration is widespread across diverse taxa in the world's lakes and seas, yet its biogeochemical consequences are still poorly understood. The biologically mediated vertical flux of material in the ocean (also known as the "biological pump") is a matter of major interest and concern, as it is thought to play an important role in regulating ocean carbon storage, and by extension, the global carbon cycle. Recent studies spanning multiple trophic levels from fish to dinoflagellates have led us to a concept of coupled vertical migrations that we refer to as "cascading migrations". That is, migrations that …
