Variability Of Paralarval-Squid Occurrence In Meter-Net Tows From East Of Florida, Usa, Carrie A. Erickson, Clyde F.E. Roper, Michael Vecchione

Ocean Engineering and Marine Sciences Faculty Publications

We attempted to determine cross-shelf, diel, and seasonal distribution patterns of paralarval cephalopods off eastern Florida during a 5-year study that employed both open-net and discrete-depth closing-net sampling. Based on our 303 samples, abundant and common squid taxa included the squid Doryteuthis spp., which tended to be in coastal and intermediate waters, and Abralia cf veranyi (Eye-Flash Squid), Illex spp. (shortfin squid), and Ommastrephidae Type A (which could include Ommastrephes bartramii [Neon Flying Squid] and Ornithoteuthis antillarum [Atlantic Bird Squid]), mostly in intermediate and Florida Current waters. Species diversity and abundance were usually greatest in Florida Current waters versus coastal …

Reef Fish Assemblage Biogeography Along The Florida Reef Tract, Cory Ames

HCNSO Student Theses and Dissertations

Understanding the biogeography of reef fish assemblages is paramount to reef conservation, management, and conducting appropriate population survey designs. Reef fish assemblages are a multispecies complex of reef-associated fish and are shaped by multiple environmental and biological factors (e.g. temperature, depth, benthic habitat, and topographic relief), which determine the species constituents residing in an area. Assemblages typically change with latitude where the number of families, genera, and/or densities of species specific to warmer climates decrease poleward into colder climate regimes. The Florida Reef Tract (FRT) extends for 595 km from the Dry Tortugas in the south-west to Martin County in …

Dynamics Of Prochlorococcus And Synechococcus At Station Aloha Revealed Through Flow Cytometry And High-Resolution Vertical Sampling, Ger J. Van Den Engh, Joseph K. Doggett, Anne W. Thompson, Martina A. Doblin, Carla N.G. Gimpel, David M. Karl

Biology Faculty Publications and Presentations

The fluorescence and scattering properties of Prochlorococcus and Synechococcus at Station ALOHA as measured by flow cytometry (termed the FCM phenotype) vary with depth and over a variety of time scales. The variation in FCM phenotypes may reflect population selection or physiological acclimation to local conditions. Observations before, during, and after a storm with deep water mixing show a short-term homogenization of the FCM phenotypes with depth, followed by a return to the stable pattern over the time span of a few days. These dynamics indicate that, within the upper mixed-layer, the FCM phenotype distribution represents acclimation to ambient light. …

"The Effects Of Ocean Warming And Sedimentation On The Survival And Growth Of Acropora Cervicornis" And "Differential Prevalence Of Chimerism During Embryogenesis In Corals", Hayley De Marchis

HCNSO Student Theses and Dissertations

Part I:

Coral reefs are essential to coastal economies, protecting coastlines from storms, and harboring high biodiversity. However, reefs are declining due to local anthropogenic stressors and ocean warming. Sedimentation, a local stressor, aggravates the impacts of warming on corals and hinders their survival and growth. Therefore, it is important to investigate whether sedimentation and temperature have a synergistic effect on vulnerable coral species, especially during earlier stages of development. To quantify these effects, survival and growth of newly settled Acropora cervicornis corals were measured at two temperatures (29 and 31°C, representing current and predicted for 2050 Summer temperatures) and …

Hardbottom Mapping And Community Characterization Of The West-Central Florida Gulf Coast, December 2011 - June 2016, Brian K. Walker, Rene Baumstark, Sean Keenan, Cory Ames

Marine & Environmental Sciences Faculty Datasets

The continental shelf off Florida’s west coast is a mosaic of fish habitats including seagrass beds and carbonate reef outcroppings (hard bottom) classified by the National Marine Fisheries Service (NMFS) as Essential Fish Habitat. Habitat maps and community baseline data, however, are nonexistent for a majority of the region. This collaborative effort between Nova Southeastern University, Florida Fish and Wildlife Conservation Commission, NMFS and other scientists will characterize and map continental shelf seagrass and hard bottom habitats in nearshore areas fished by many recreational fishermen. Objectives include: 1) map hard bottom and seagrass beds using various data types including sonar …

Evaluating The Ecological Status Of The Introduced Nile Monitor (Varanus Niloticus) In Florida: Forecasting Presence And Population Expansion Using Computational Geographic Information Systems, Noah G. Cohen

HCNSO Student Theses and Dissertations

The Nile monitor (Varanus niloticus) is a large, carnivorous lizard that has become a notorious invasive species in Florida, USA. Initially released in the 1980s from the pet trade, the species has since established at least three breeding populations and spread throughout much of southern Florida. While current control efforts have failed to eradicate V. niloticus, it is important to attain a better understanding of its invasive dynamics to guide and inform better control strategies. In this study, available georeferenced records of V. niloticus in Florida were compiled and linked to a habitat classification map to evaluate ecotype preferences. Factored …

Multimodal In Situ Datalogging Quantifies Inter-Individual Variation In Thermal Experience And Persistent Origin Effects On Gaping Behavior Among Intertidal Mussels (Mytilus Californianus), Luke P. Miller, Wesley Dowd

Faculty Publications, Biological Sciences

In complex habitats, environmental variation over small spatial scales can equal or exceed larger-scale gradients. This small-scale variation may allow motile organisms to mitigate stressful conditions by choosing benign microhabitats, whereas sessile organisms may rely on other behaviors to cope with environmental stresses in these variable environments. We developed a monitoring system to track body temperature, valve gaping behavior and posture of individual mussels (Mytilus californianus) in field conditions in the rocky intertidal zone. Neighboring mussels' body temperatures varied by up to 14°C during low tides. Valve gaping during low tide and postural adjustments, which could theoretically lower …

Thermal History And Gape Of Individual Mytilus Californianus Correlate With Oxidative Damage And Thermoprotective Osmolytes, Lani Gleason, Luke Miller, Jacob Winnikoff

Faculty Publications, Biological Sciences

The ability of animals to cope with environmental stress depends – in part – on past experience, yet knowledge of the factors influencing an individual's physiology in nature remains underdeveloped. We used an individual monitoring system to record body temperature and valve gaping behavior of rocky intertidal zone mussels (Mytilus californianus). Thirty individuals were selected from two mussel beds (wave-exposed and wave-protected) that differ in thermal regime. Instrumented mussels were deployed at two intertidal heights (near the lower and upper edges of the mussel zone) and in a continuously submerged tidepool. Following a 23-day monitoring period, measures of …

Microbial And Genomic Analysis Of Environmental Samples In Search Of Pathogenic Salmonella, Jorie L. Skutas

HCNSO Student Theses and Dissertations

Salmonellosis or “food poisoning” is a foodborne infection brought on by the pathogen Salmonella from the ingestion of the bacterium on contaminated foods such as vegetables. Infection from Salmonella leads to the highest incidence of hospitalizations and deaths each year, compared to any other bacterial foodborne illness. South Florida is the second largest agricultural winter vegetable producer in the United States, and contamination of vegetables is often observed in preharvest practices. A hardy bacterium, Salmonella, has been shown to live up to 6 weeks in soil and water up to 42°C without a host.

Seasonal Shifts In Bacterial Community Responses To Phytoplankton-Derived Dissolved Organic Matter In The Western Antarctic Peninsula, Catherine M. Luria, Linda A. Amaral-Zettler, Hugh W. Ducklow, Daniel J. Repeta, Andrew L. Rhyne, Jeremy J. Rich

Arts & Sciences Faculty Publications

Bacterial consumption of dissolved organic matter (DOM) drives much of the movement of carbon through the oceanic food web and the global carbon cycle. Understanding complex interactions between bacteria and marine DOM remains an important challenge. We tested the hypothesis that bacterial growth and community succession would respond differently to DOM additions due to seasonal changes in phytoplankton abundance in the environment. Four mesocosm experiments were conducted that spanned the spring transitional period (August-December 2013) in surface waters of the Western Antarctic Peninsula (WAP). Each mesocosm consisted of nearshore surface seawater (50 L) incubated in the laboratory for 10 days. …

Timing Anthropogenic Stressors To Mitigate Their Impact On Marine Ecosystem Resilience, Paul Pao-Yen Wu, Kerrie Mengersen, Kathryn Mcmahon, Gary A. Kendrick, Kathryn Chartrand, Paul H. York, Michael A. Rasheed, M. Julian Caley

Research outputs 2014 to 2021

Better mitigation of anthropogenic stressors on marine ecosystems is urgently needed to address increasing biodiversity losses worldwide. We explore opportunities for stressor mitigation using whole-of-systems modelling of ecological resilience, accounting for complex interactions between stressors, their timing and duration, background environmental conditions and biological processes. We then search for ecological windows, times when stressors minimally impact ecological resilience, defined here as risk, recovery and resistance. We show for 28 globally distributed seagrass meadows that stressor scheduling that exploits ecological windows for dredging campaigns can achieve up to a fourfold reduction in recovery time and 35% reduction in extinction risk. Although …

Species-Specific Metabolism Of Naphthalene And Phenanthrene In 3 Species Of Marine Teleosts Exposed To Deepwater Horizon Crude Oil, Erin Pulster, Kevan Main, Dana Wetzel, Steven Murawski

C-IMAGE Publications

The 2 most abundant polycyclic aromatic hydrocarbons (PAHs) measured in Deepwater Horizon crude oil, naphthalene and phenanthrene, and their associated homologs have both been shown to be acutely toxic in fish. Although fish have a relatively high metabolic capacity for PAHs, hydroxylated PAH (OH-PAH) derivatives formed during the initial metabolic response can negatively impact the health of fish. Species-specific metabolism of naphthalene and phenanthrene was evaluated in 3 marine teleosts, red drum (Scianops ocellatus), Florida pompano (Trachinotus carolinus), and southern flounder (Paralichthys lethostigma). Fish were exposed to Deepwater Horizon crude oil by intraperitoneal injections at time 0 and 48 h, …

Validating Sidescan Sonar As A Fish Survey Tool Over Artificial Reefs, Michael A. Bollinger, Richard Kline

School of Earth, Environmental, & Marine Sciences Faculty Publications

Visual observation methods via SCUBA are commonly used to survey artificial reef fish, although conditions in the Gulf of Mexico often make surveys difficult or even dangerous for divers. In this study, sidescan sonar was used to quantify water-column fish abundance and was compared to the established visual observation methods on SCUBA over four reef sites. Calibrated intensity values measured from sidescan sonar echo returns were used to estimate fish body length and to calculate scaled biomass (g/m2 reef) from a pooled fish length–weight relationship of commonly observed reef fish in the area. Sidescan sonar methods were equivalent to SCUBA …

Composition And Quantification Of Polycyclic Aromatic Hydrocarbons In Deep-Pelagic Fauna. Cruises Dp02, Dp03, And Dp04 From August 2015 - August 2016, Isabel C. Romero
