Environmental Influences On Juvenile Fish Abundances In A River-Dominated Coastal System, Laure Carassou, Brian Dzwonkowski, Frank J. Hernandez, Jr., Sean P. Powers, William M. Graham, Kyeong Park, John Mareska

University Faculty and Staff Publications

We investigated the influence of climatic and environmental factors on variations in juvenile abundances of marine fishes in a river-dominated coastal system of the north-central Gulf of Mexico, where an elevated primary productivity sustains fisheries of high economic importance. Fish were collected monthly with an otter trawl at three stations near Mobile Bay from 1982 to 2007. Fish sizes were used to isolate juvenile stages within the data set, and monthly patterns in juvenile fish abundance and size were then used to identify seasonal peaks for each species. The average numbers of juvenile fish collected during these seasonal peaks in …

Field Ecology Patterns Of High Latitude Coral Communities, Kristi A. Foster

HCNSO Student Theses and Dissertations

Some climate models predict that, within the next 30-50 years, sea surface temperatures (SSTs) will frequently exceed the current thermal tolerance of corals (Fitt et al. 2001; Hughes et al. 2003; Hoegh-Guldberg et al. 2007). A potential consequence is that mass coral bleaching may take place (i) during warm El Niño-Southern Oscillation (ENSO) events which are predicted to occur in some regions more frequently than the current 3-7 year periodicity (Hoegh-Guldberg 1999; Sheppard 2003) or (ii) perhaps as often as annually or biannually if corals and their symbionts are unable to acclimate to the higher SSTs (Donner et al. 2005, …

Green Marine Construction, Sylvain Pioch, Kirk Kilfoyle, Harold Levrel, Richard E. Spieler

Marine & Environmental Sciences Faculty Articles

The oceans incorporate three-quarters of the Earth's surface, and most of humanity lives in coastal regions. For example, more than half of the total U.S. population presently lives in coastal areas, and the coastal population is projected to increase by 7 million between now and 2015. Similar projections can be made for other developed countries many of which depend on the coastal zone as a major source of tourism-related income. The long-term ecological health and sustainability of the marine and coastal environments are obviously at risk. Coastal projects such as beach re-nourishment, housing developments, and pipe-line, harbor and marina construction …

Circulation Of The Western Antarctic Peninsula: Implications For Biological Production, Maria Andrea Piñones Valenzuela

OES Theses and Dissertations

The western Antarctic Peninsula (wAP) continental shelf is characterized by large persistent populations of Antarctic krill ( Enphausia superba) and by regions of enhanced concentrations of marine mammals and other predators (hot spots). This study focused on understanding the role of ocean circulation in providing retention/connectivity of wAP Antarctic krill populations and in maintaining biological hot spot regions. Numerical Lagrangian particle tracking simulations obtained from the Regional Ocean Modeling System (ROMS) configured for the wAP region provided quantitative estimates of retention, immigration and emigration from the wAP continental shelf. Additional simulations with a one-dimensional temperature-dependent growth model for krill …

Present Limits To Heat-Adaptability In Corals And Population-Level Responses To Climate Extremes, Bernhard Riegl, Samuel J. Purkis, Ashraf S. Al-Cibahy, Mohammed A. Abdel-Moati, Ove Hoegh-Guldberg

Marine & Environmental Sciences Faculty Articles

Climate change scenarios suggest an increase in tropical ocean temperature by 1–3°C by 2099, potentially killing many coral reefs. But Arabian/Persian Gulf corals already exist in this future thermal environment predicted for most tropical reefs and survived severe bleaching in 2010, one of the hottest years on record. Exposure to 33–35°C was on average twice as long as in non-bleaching years. Gulf corals bleached after exposure to temperatures above 34°C for a total of 8 weeks of which 3 weeks were above 35°C. This is more heat than any other corals can survive, providing an insight into the present limits …

Background

Coral reefs are facing increasing pressure from natural and anthropogenic stressors that have already caused significant worldwide declines. In January 2010, coral reefs of Florida, United States, were impacted by an extreme cold-water anomaly that exposed corals to temperatures well below their reported thresholds (16°C), causing rapid coral mortality unprecedented in spatial extent and severity.

Methodology/Principal Findings

Reef surveys were conducted from Martin County to the Lower Florida Keys within weeks of the anomaly. The impacts recorded were catastrophic and exceeded those of any previous disturbances in the region. Coral mortality patterns were directly correlated to in-situ and satellite-derived …

Application Of A Gene-Based Population Dynamics Model To The Optimal Egg Size Problem: Why Do Bivalve Planktotrophic Eggs Vary In Size?, Eric N. Powell, Jason Morson, John M. Klinck

CCPO Publications

The presumption is that egg quality influences larval survival and that egg size influences egg quality. Thus, larger eggs should be favored by selection. Counterweighing the tendency for egg size to increase is the number of eggs that can be produced if egg size remains small. We examine how egg size and egg number counterbalance in Crassostrea oysters, resulting in an average egg size near 50 mu m. Simulations imposing a diversity of ranges in larval survivorship-from little advantage for large eggs relative to small eggs to a great advantage-yield some anticipated outcomes in which genotypes generating larger eggs are …

A Molecular Assessment Of Speciation And Evolutionary History Of The Globally Distributed Spotted Eagle Ray (Aetobatus Narinari), Vincent P. Richards, Marcy Henning, Wayne Witzell, Mahmood S. Shivji

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

The spotted eagle ray (Aetobatus narinari), a species of conservation concern (Near Threatened IUCN category) is commonly associated with coral reef ecosystems worldwide where it is likely to play an important predatory role. Currently described as a single, circumglobally distributed species, geographic differences in parasite diversity have led to suggestions that A. narinari may constitute a species complex. There has been no systematic evidence to support this suggestion, however. If multiple species of spotted eagle ray exist, each will likely posses decreased geographic ranges and population sizes, altering the impacts of threats and requiring separate assessments of conservation …

Study Of The Far Wake Of A Large Ship, M. Gilman, Alexander Soloviev, H. Graber

Marine & Environmental Sciences Faculty Articles

A large dataset of high-resolution photographic images of far wakes of a volunteer observing ship (Royal Caribbean’s Explorer of the Seas) has been acquired under various meteorological conditions and ship operation modes. This work presents the description of instrumentation, methodology, and the results of the experiment. Environmental and ship operation factors that affect appearance and geometric properties of ship wakes in photographic and satellite-based radar images have been analyzed. The photo imagery reveals an asymmetry of the wake depending on wind direction relative to the ship course. In addition, a good agreement between the averaged shape of the wakes …

Nudibranch Predators Of Octocorallia, Eric Brown

HCNSO Student Capstones

Nudibranchs are soft-bodied marine heterobranch gastropod molluscs which lack a shell and mantle cavity. The basic body plan is bilaterally symmetrical with an expanded notum, but in regards to other physical characteristics they exhibit a wide range of forms. Compared to other molluscs, evolutionarily the head and body became flattened and streamlined and tentacles have been lost or shifted to different areas of the body. Nudibranchs are found in many variations of size and color; despite the fact that these animals in general are noted for flamboyant colors and prominent external anatomical structures, many species rely upon a more cryptic …

A New Species Of Leucothoid Amphipod, Anamixis Bananarama, Sp. N., From Shallow Coral Reefs In French Polynesia (Crustacea, Amphipoda, Leucothoidae), James Darwin Thomas, Traudl Krapp-Shickel

Marine & Environmental Sciences Faculty Articles

Both leucomorph and anamorph developmental stages of Anamixis bananarama sp. n., are illustrated and described from shallow back reef environments of Moorea, French Polynesia. Distinguished by vestigial fi rst gnathopods that persist in post-transformational adult males, this is the second species in the genus to exhibit this unusual character. In other features such as coxae and second gnathopods A. bananarama sp. n. resembles other Pacific Plate endemics of Anamixis known from the region. Specific host association is not documented but suspected to be small calcareous asconoid sponges associated with coral rubble.

Super-Aggregations Of Krill And Humpback Whales In Wilhelmina Bay, Antarctic Peninsula, Douglas P. Nowacek, Ari S. Friedlaender, Patrick N. Halpin, Elliott L. Hazen, David W. Johnston, Andrew J. Read, Boris Espinasse, Meng Zhou, Yiwu Zhu

Environmental, Earth, and Ocean Sciences Faculty Publication Series

Ecological relationships of krill and whales have not been explored in the Western Antarctic Peninsula (WAP), and have only rarely been studied elsewhere in the Southern Ocean. In the austral autumn we observed an extremely high density (5.1 whales per km²) of humpback whales (Megaptera novaeangliae) feeding on a super-aggregation of Antarctic krill (Euphausia superba) in Wilhelmina Bay. The krill biomass was approximately 2 million tons, distributed over an area of 100 km² at densities of up to 2000 individuals m⁻³; reports of such ‘super-aggregations’ of krill have been absent in …

Difficulties in scaling up theoretical and experimental results have raised controversy over the consequences of biodiversity loss for the functioning of natural ecosystems. Using a global survey of reef fish assemblages, we show that in contrast to previous theoretical and experimental studies, ecosystem functioning (as measured by standing biomass) scales in a non-saturating manner with biodiversity (as measured by species and functional richness) in this ecosystem. Our field study also shows a significant and negative interaction between human population density and biodiversity on ecosystem functioning (i.e., for the same human density there were larger reductions in standing biomass at more …

The Effect Of Air Temperature On The Incubation Period And Hatching Success Of In Situ Loggerhead Sea Turtle (Caretta Caretta) Clutches In Broward County, Florida, Lucy Teal Kawana, Curtis M. Burney, Louis Fisher

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

The survival rates of pre-emergent sea turtle hatchlings are critically dependent upon temperature. This study aims to determine if changes in air temperature have influenced the incubation time and/or the survivorship of the pre-emergent loggerhead sea turtle (Caretta caretta) hatchlings for past sea turtle nesting seasons in Broward County. Air temperature data within the hatching seasons of 1999 to 2009 was obtained from the NOAA National Climatic Data Center’s Fort Lauderdale beach station. The loggerhead sea turtle hatching data collected by the Broward County Sea Turtle Conservation Program from the same time period was examined to assess the …

Population Dynamics Of Sheepshead (Archosargus Probatocephalus; Walbaum 1792) In The Chesapeake Bay Region: A Comparison To Other Areas And An Assessment Of Their Current Status, Joseph Charles Ballenger

OES Theses and Dissertations

Sheepshead recently have seen an increase in fishing pressure in Virginian waters of the Chesapeake Bay. This increase in fishing pressure has led to demands to install effective management measures to protect the fishery. However, no study regarding the population dynamics, and thus potential yield, of sheepshead has been conducted north of Cape Hatteras. We addressed the need for information regarding the population dynamics of Chesapeake Bay sheepshead by investigating their age distribution, growth rate and reproductive biology. We used this information to construct yield-per-recruit models, which local management agencies may use in the formation of scientifically based management measures. …

Alternate Trophic Pathways Support Enhanced Bathypelagic Biomass Over A Mid-Ocean Ridge System, Tracey Sutton, Jeanna M. Hudson, Joel C. Hoffman, Tone Falkenhaug, Odd Aksel Bergstad, M. Heino

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

A classic paradigm of oceanic ecology is that pelagic animal biomass decreases exponentially with depth. Results of a muti-year study of the distribution and ecology of the pelagic fauna over the northern Mid-Atlantic Ridge (MAR), from Iceland to the Azores, revealed that water column biomass maxima can occur at deep meso- and bathypelagic depths (>750 m). Further, topographic association of the deep-pelagic fauna occurs at some locations. For example, bathypelagic fish abundance and biomass maxima were observed within the benthic boundary layer (<200 m above the bottom) during the 2004 G.O. Sars MAR-ECO expedition. Results of a pelagic food-web model over the MAR suggest that alternate trophic pathways contribute significantly to this deep biomass maxima. Consumption of decapod crustacea and gelatinous zooplankton represented major portions of the total consumption by pelagic fishes. Stable isotope analysis of 63 species, from zooplankton to large benthic predators, suggest short food chains and high trophic efficiency may account for enhanced deep-pelagic biomass.

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 …

Marine & Environmental Sciences Faculty Articles

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 …

Sampling Methods For Acropora Corals, Other Benthic Coral Reef Organisms, And Marine Debris In The Florida Keys: Field Protocol Manual For 2011-2012 Assessments, Steven Miller, Leanne M. Rutten, Mark Chiappone

Marine & Environmental Sciences Faculty Reports

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 …

Basal Food Web Dynamics In A Natural Eelgrass (Zostera Marina) Community: Cage-Free Field Experimentation, Matthew A. Whalen

Dissertations, Theses, and Masters Projects

The relative strength of bottom-up and top-down processes operating within food webs is a fundamental determinant of community structure and function. In marine systems, inconspicuous but often highly abundant invertebrate herbivores (mesograzers) are implicated as strong consumers of primary production and important prey for higher-order consumers. Because of their small size, however, mesograzer abundance is not easily manipulated in the field, which limits our ability to adequately assess their grazing impacts. Seagrass systems present a pressing need for the study of food web dynamics because anthropogenic nutrient and sediment inputs decrease the amount of light reaching seagrass leaves, which limits …

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 …

Behavior Constrains The Dispersal Of Long-Lived Spiny Lobster Larvae, Mark J. Butler Iv, Claire B. Paris, Jason S. Goldstein, Hirokazu Matsuda, Robert K. Cowen

Biological Sciences Faculty Publications

Behavior such as ontogenetic vertical migration (OVM) limits the transport of marine larvae with short pelagic larval durations (PLDs), but its effect on the supposed long-distance dispersal of larvae with long PLDs is unknown. We conducted laboratory tests of ontogenetic change in larval phototaxis and examined size-specific patterns of larval distribution in the plankton to characterize OVM in the Caribbean spiny lobster Panulirus argus during its long (6 mo) PLD. We then used a coupled biophysical model to explore the consequences of OVM and hydrodynamics on larval P. argus dispersal in the Caribbean Sea. Larvae reared in the laboratory were …

Cascading Migrations And Implications For Vertical Fluxes In Pelagic Ecosystems, Stephen M. Bollens, Gretchen Rollwagen-Bollens, Joel A. Quenette, Alexander B. Bochdansky

OES Faculty Publications

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 …
