Psychology Faculty Publications
Lateralization of behaviors and information processing are common across species. Hypothesized to be crucial for more efficient responding to environmental stimuli, lateralization has been investigated for a number of topics. Cetaceans are proposed to be hemispheric specialists, given a small corpus callosum, complete decussation of the optic nerve, and the ability to respond to a different visual stimulus presented to each eye simultaneously. Research with cetaceans has shown strong biases in a number of behaviors, including swimming, foraging, social interactions, and responses to myriad visual stimuli. Given similar evolutionary pressures, different species of cetaceans should display similar lateralized preferences. Previous …

Continued Spread Of The Seagrass Halophila Stipulacea In The Caribbean: Documentation In Puerto Rico And The British Virgin Islands, Hector Ruiz, David L. Ballantine, Jorge Sabater
Gulf and Caribbean Research
The geographical spread of Halophila stipulacea in the Caribbean since its first documentation in Grenada in 2001 has been impressive, as it has since been reported from most of the Caribbean. We now document its presence in the northern Caribbean at Culebra Island and in the Atlantic at a site between Humacao and Vieques Island, Puerto Rico. We further report the seagrass from Road Harbour, Tortola, British Virgin Islands. Spread of the invasive seagrass Halophila stipulacea is probably largely driven by Caribbean current patterns from its likely point of introduction in the southeast of the Caribbean basin. Continued spread into …

Luminescent Syllid (Odontosyllis Sp.) Courtship Display Densities Vary Across Marine Habitats Around South Water Caye, Belize, Mitchel Mccloskey, Joshua Scheil, Gregory J. Sandland, Gretchen A. Gerrish
Gulf and Caribbean Research
Bright—green luminescent clouds frequently occur at the surface of shallow waters of the Caribbean Sea. These clouds are produced by syllid polychaetes during courtship. Although temporal variation in the occurrence of these courtship displays has been documented throughout the diurnal and lunar cycle, other factors such as habitat type have not been well studied. In this study, we investigated how syllid courtship—display densities varied across 3 substrate types (grassbed, rubble and coral) over a 3 day period. In line with previous studies, we found that syllid courtship displays occurred over seagrass and rubble substrates; however, we also found that display …

Growth And Spawning Dynamics Of Southern Flounder In The North-Central Gulf Of Mexico, Morgan M. Corey, Robert T. Leaf, Nancy Brown-Peterson, Mark S. Peterson, Samuel D. Clardy, David Dippold
Faculty Publications
Southern Flounder Paralichthys lethostigma is the most commonly harvested flatfish in the north-central Gulf of Mexico (GOM), yet knowledge of this species’ growth and reproduction is limited for the Mississippi region. Given the offshore spawning migrations and likely mixing between state-managed units of the GOM Southern Flounder stock, small-scale environmental influences may constitute a major driver of life history dynamics during early life residency in nearshore estuaries. Therefore, estimates of local demographic characteristics are needed for effective fishery management. Here, we describe critical life history traits of Southern Flounder, including estimation of growth rates and maturity. The three-parameter von Bertalanffy …

Loop Current Spin-Off Eddies, Slope Currents And Dispersal Of Reef Fish Larvae From The Flower Gardens National Marine Sanctuary And The Florida Middle Grounds, Donald R. Johnson, Harriet Perry, Guillermo Sanchez-Rubio, Mark A. Grace
Gulf and Caribbean Research
Large energetic spin—off eddies from Loop Current intrusions into the Gulf of Mexico play a major role in water exchange between the continental shelf and the deep basin in the northern Gulf. Reef fish larvae, spawned on the outer shelf and planktonic during their early life history, are broadly dispersed by this mechanism, but may be lost to the cohort by transport away from suitable settlement habitat. In this study, satellite altimeter data—assimilative ocean model currents (HYCOM) from 2003—2015 are used to calculate kinetic energy of the mixed layer over the upper continental slope (200 m —1000 m) due to …

Population Characteristics And Trophic Interactions Between Pacific Mole Crabs And Redtail Surfperch On Northern California Sandy Beaches, Michelle Lynn Succow
Cal Poly Humboldt theses and projects
A network of marine protected areas (MPAs) was established to protect northern California coastal habitats in December 2012. Populations of two indicator species, Amphistichus rhodoterus (redtail surfperch) and Emerita analoga (pacific mole crabs) were characterized within MPAs and reference sites to provide baseline ecological information for this region. Data were gathered using a series of simple field surveys (hook and line fishing surveys for A. rhodoterus along with core and transect surveys for E. analoga). Relative abundance, lengths, and sex ratios of A. rhodoterus did not differ between MPAs and their respective reference sites, whereas condition (overall health) increased …

Air- Sea Interactions And Ocean Dynamics In The Southwest Tropical Indian Ocean, Jessica Maureen Burns
Theses and Dissertations
The Southwest Tropical Indian Ocean (SWTIO) features a unique, seasonal upward lift of the thermocline, which is known as the Seychelles-Chagos Thermocline Ridge (SCTR; 55°E-65°E, 5°S-12°S). It is known that a high correlation exists between the depth of the thermocline and sea surface temperature (SST; a key ingredient for tropical cyclogenesis). With a particular focus on 2012/2013, this study reveals the dynamic properties of the SCTR that play an important role in the modulation of tropical cyclones in the SWTIO. Phenomena including Indian Ocean Dipole (IOD) and El Niño Southern Oscillation (ENSO) are also well correlated to cyclogenesis through changes …

The Influence Of Phytoplankton Size And Community Composition On Carbon Cycling And Planktonic Food Webs In The Sargasso Sea, Bridget Elise Cotti-Rausch
Theses and Dissertations
The Sargasso Sea is a dynamic physical environment located in the western North Atlantic where strong seasonal variability combines with forcing by mesoscale (~100 km) eddies. These drivers determine nutrient, light, and temperature regimes, and ultimate the size, composition and productivity of the phytoplankton community. My general objective was to determine how the structure and function of planktonic communities affected carbon export from the surface ocean in the Sargasso Sea. On four cruises (2011 and 2012; one eddy per cruise), I investigated links between water column structure, plankton community composition, size, and primary production (PP). I then combined PP data …

Molecular Exploration Of Bioavailable Dissolved Organic Matter Across Aquatic Ecosystems, Yuan Shen
Theses and Dissertations
Dissolved organic matter (DOM) in aquatic ecosystems is a large reservoir of reduced carbon that is mostly resistant to degradation. A small fraction of DOM cycles relatively quickly and is biologically utilized on timescales of days to months. This bioavailable DOM (BDOM) supports aquatic food webs, drives major elemental cycles, and is coupled to atmospheric CO2. Despite wide-ranging importance, bioavailability of DOM and its linkages to ecosystem properties (e.g., primary production, nutrients) are poorly characterized, particularly at the ecosystem level. Bioassay experiments are commonly used to determine BDOM, but this approach alters conditions and has limited spatial and temporal coverage. …

Survey Gear Comparisons And Shark Nursery Habitat Use In Southeast Georgia Estuaries, Jeffrey Cohen Carpenter
UNF Graduate Theses and Dissertations
Gill nets and longlines were compared as shark nursery sampling methodologies in inshore waters of Georgia to (1) assess differences in gear selectivity, bias, and stress of capture and (2) determine potential relationships between habitat features and shark distribution and abundance. Gear selectivity varied between gears as a function of both species and life stage resulting in significantly different estimates of species and life stage compositions. Juvenile bonnetheads (Sphyrna tiburo) and young of the year blacktip sharks (Carcharhinus limbatus) experienced significantly higher stress from gill net capture than longline. Major sources of bias are thought to …

Wind Driven Shelf Circulation: Effects Of Shoreline Orientation, Bathymetry, And Surface Cooling, Xiaodong Wu
Theses and Dissertations
The dynamic region extending from the inner- to outer-shelf is the nearshore region where an accurate understanding of the development of cross-shore flows is important as they control the exchange of constituents (e.g., pollutants, larvae, heat and biota) between the coastline and the open ocean. These flows are driven by a variety of forces, including wind and buoyancy. The wind forcing relevant to shelf circulation broadly falls within the synoptic scale of storm events, consisting of frontal systems (cold and warm fronts) and tropical storms. The buoyancy on the shelf is characterized by a vertical stratification or a pronounced cross-shore …

Development Of A Sandwich Hybridization Assay For The Harmful Cyanobacteria Microcystis Spp., Nicole M. Dearth
Theses and Dissertations
Cyanobacteria are responsible for the largest number of harmful blooms (HABs) worldwide. HABs caused by the genus Microcystis pose public health threats because they often occur within close proximity to humans and produce microcystin (hepatotoxin), which can contaminate drinking water and recreational areas. Novel molecular techniques facilitate monitoring, ‘early warnings’ of HAB events, and appropriate management responses. Sandwich hybridization assay (SHA), the technique considered here, directly (no amplification) identifies and quantifies planktonic species using ribosomal RNA (rRNA)-targeted oligonucleotides. This project developed SHA for Microcystis 16S rRNA and validated the assay using laboratory cultures and samples from a multi-specific cyanobacteria bloom …
Marine Phosphorus Biogeochemistry Ecological Insights From Analytical Chemistry,

University of South Carolina
Marine Phosphorus Biogeochemistry Ecological Insights From Analytical Chemistry, Douglas W. Bell
Theses and Dissertations
The supply of phosphorus (P) directly impacts the growth and speciation of marine microbes (i.e., phytoplankton, bacteria, Archaea). In turn, microbial communities shape the magnitude and rate of marine biogeochemical cycles, ultimately affecting global climate and food production. This dynamic reflects the continuum of temporal and spatial scales at which the marine P cycle operates. However, linking multiple scales of cycling remains a consistent challenge. The primary objective of my dissertation was to gain insight into marine P biogeochemistry, by means of analytical chemistry, at the molecular and environmental scales of cycling. The first component of my research was to …

Today the biggest incentive to attempt the restoration and protection of estuarine systems is their widely recognized ecological and economic importance. In the reconstruction of an estuary where the original aquatic communities disappeared before the restoration interventions, the fish assemblage is an adequate source of indicators of initial recovery. Following substantial restoration efforts, this study reports on the biannual for a lustrum monitoring and assessment of a severely degraded estuary (Garrapatas) in terms of its fish assemblage using a reference estuary (Barberena) in Tamaulipas, Mexico. Twenty fishes were associated with the restoring and reference estuaries. Species composition (richness, abundance, dominance) …

A major impact of global climate change has been the marked increase worldwide in the incidence of coastal hypoxia (dissolved oxygen, DOhif-α; neuronal nitric oxide synthase, nNOS; and insulin-like growth factor binding protein, igfbp mRNAs and protein carbonyl (PC, an oxidative stress indicator) content were elevated several-fold in brain and liver tissues of croaker collected from nGOM hypoxic sites. All of these molecular and biochemical biomarkers were also upregulated ~3-10-fold in croaker brain and liver tissues within 1–2 days of hypoxia exposure in controlled laboratory experiments. These results suggest that hif-αs, nNOS and igfbp-1 transcripts and PC contents …

A Comparison Of Computational Methods For Estimating Estuarine Production And Respiration From Diel Open Water Dissolved Oxygen Measurements, Spencer Tassone
Theses and Dissertations
Diel dissolved oxygen (DO) data were used to characterize seasonal, inter-annual, and longitudinal variation in production and respiration for the James River Estuary. Two computational methods (Bayesian and bookkeeping) were applied to these data to determine whether inferences regarding DO metabolism are sensitive to methodology. Net metabolism was sensitive to methodology as Bayesian results indicated net heterotrophy (production < respiration) while bookkeeping results indicated net autotrophy (production > respiration). Differences in net metabolism among the methods was due to low seasonal variation in respiration using the Bayesian method, whereas bookkeeping results showed a strong correlation between production and respiration. Bayesian results suggest a dependence on allochthonous organic matter (OM) whereas …
