Human Disturbance Of Seagrass Beds In Hoga Island, Indonesia : Impacts On Edge Effects, Anthony John Suleski
Theses, Dissertations and Culminating Projects
Ecosystems are broad classifications of areas where overlapping communities exist which can contain relatively high faunal and floral diversity. These communities characteristically are often influenced by external forces. Disturbances can create incongruencies in these communities and have been demonstrated to change community dynamics in varying ways. Humans are responsible for many disturbances which alter habitat and community structure and many habitat edges or ecotones are artificially created by these human disturbances. In Wakatobi National Park, Hoga Island, Indonesia, three bays exist and are in close proximity to one another with varying levels of human influence. This study investigated how anthropogenic …

Record Body Size For The Red Lionfish, Pterois Volitans (Scorpaeniformes), In The Southern Gulf Of Mexico, Alfonso Aguilar-Perera, Leidy Perera-Chan, Luis Quijano-Puerto
Gulf and Caribbean Research
Non-native species are those that have been transported, via human actions, from one continent and introduced into another (Lockwood et al. 2007). In the 1980s, red lionfish, Pterois volitans (Linnaeus, 1758), traded in the US aquarium industry from the Pacific Ocean, was introduced into the coral reefs off Florida's coast by aquarium hobbyists (Morris and Whitfield 2009). It is unknown how this introduction occurred, but after more than 20 years the red lionfish population is widespread, occupying a large portion of the Western Atlantic (Schofield 2010) where it represents a threat to the marine ecosystem (Green et al. 2012). The …
Time-Activity Budgets Of Stoplight Parrotfish (Scaridae: Sparisoma Viride) In Belize: Cleaning Invitation And Diurnal Patterns,

Time-Activity Budgets Of Stoplight Parrotfish (Scaridae: Sparisoma Viride) In Belize: Cleaning Invitation And Diurnal Patterns, Wesley A. Dent, Gary R. Gaston
Gulf and Caribbean Research
The primary objective of this study was to analyze diurnal behavior of Sparisoma viride in South Water Caye Marine Reserve (SWCMR), Belize. Time-activity budgets were used to characterize behavior (using swimming, feeding, hovering, sheltering, defecating, and cleaning categories) during the diel cycle, and to illustrate differences among the life phases of this species.

Effects Of Black Mangrove (Avicennia Germinans) Expansion On Saltmarsh (Spartina Alterniflora) Benthic Communities Of The South Texas Coast, Jessica Lunt, Kimberly Mcglaun, Elizabeth M. Robinson
Gulf and Caribbean Research
This study examined the effects of mangrove expansion on benthic communities. This was accomplished by examining plant composition, benthic community composition, and belowground root biomass. Two sites were examined: Corpus Christi Pass, Corpus Christi, TX where mangroves have become more common in the last decade and the Lower Laguna Madre, South Padre Island, TX where mangroves are well established. This research seeks to provide preliminary results to provide direction for future studies examining the interplay of S. alterniflora and A. germinans habitat on benthic communities. We hypothesize that the more established site of South Padre Island will have greater numbers …

Doc Dynamics In Eddies Of The Sargasso Sea, Eric Matthew Lachenmyer
Theses and Dissertations
Bacterial productivity and size-fractioned rates of dissolved organic carbon (DOC) excretion from primary and secondary producers were measured in two eddy types, one anti-cyclonic (February 2012) and one cyclonic eddy (July 2012), in the Sargasso Sea. Bacterial productivity (BP) rates in the cyclonic eddy were highest in the center (9.2 mg C m-2d-1) and edge (10.4 mg C m-2d-1) of the eddy compared to the anti-cyclone center (2.2 mg C m-2d-1) and edge (5.1 mg C m-2d-1). Rates of DOC excretion from14C-tracer experiments were not significantly higher than background; lack of accumulation of labeled material indicated very fast uptake of …

The Effects Of Thermal Stress And Algal Competition On The Early Life-History Stages Of Porites Astreoides And The Development Of Stress-Detecting Biomarkers For Use In Scleractinan Corals, Kevin C. Olsen
UNF Graduate Theses and Dissertations
Scleractinian coral populations are declining worldwide in response to numerous stressors operating on both global and regional scales. Rising sea surface temperatures associated with global climate change and the increasing frequency of coral-macroalgae competitive interactions are two of the gravest ecological drivers facing coral reef ecosystems. However, little is known about how these stressors interact to impact corals, their health, and potential modes of population recovery. These threats also highlight the need to develop reliable techniques that detect stress in multiple life-history stages of hermatypic corals prior to the degradation of coral reef habitats. To address these concerns we evaluated …

The Spacial And Temporal Community Structure Of Ichthyoplankton In A Northeast Florida Estuary : A Study Of Ingress At A Faunal Boundary, Breanna Korsman
UNF Graduate Theses and Dissertations
Estuaries are widely recognized as important habitats for the early life history stages of commercially and recreationally important marine fish species. In general the estuaries of northeast Florida are understudied, and there is a need to characterize the ichthyoplankton community at this important faunal boundary between temperate and tropical marine zones. To determine community structure and temporal patterns in the distribution and abundance of larval fish ingressing in to the Guana-Tolomato-Matanzas (GTM) estuary through its two inlets (St. Augustine and Matanzas), ichthyoplankton were sampled bi-weekly for one year at both inlets during nighttime spring flood tides beginning in March 2012. …

Habitat Availability And Heterogeneity And The Indo-Pacific Warm Pool As Predictors Of Marine Species Richness In The Tropical Indo-Pacific, Jonnell C. Sanciangco, Kent E. Carpenter, Peter J. Etnoyer, Fabio Moretzsohn
Biological Sciences Faculty Publications
Range overlap patterns were observed in a dataset of 10,446 expert-derived marine species distribution maps, including 8,295 coastal fishes, 1,212 invertebrates (crustaceans and molluscs), 820 reef-building corals, 50 seagrasses, and 69 mangroves. Distributions of tropical Indo-Pacific shore fishes revealed a concentration of species richness in the northern apex and central region of the Coral Triangle epicenter of marine biodiversity. This pattern was supported by distributions of invertebrates and habitat-forming primary producers. Habitat availability, heterogeneity, and sea surface temperatures were highly correlated with species richness across spatial grains ranging from 23,000 to 5,100,000 km(2) with and without correction for autocorrelation. The …

Genetic Population Structure Of Us Atlantic Coastal Striped Bass (Morone Saxatilis), David T. Gauthier, Corinne A. Audemard, Jeanette E. L. Carlsson, Tanya L. Darden, Michael R. Denson, Kimberly S. Reece, Jens Carlsson
Biological Sciences Faculty Publications
Genetic population structure of anadromous striped bass along the US Atlantic coast was analyzed using 14 neutral nuclear DNA microsatellites. Young-of-the-year and adult striped bass (n = 1114) were sampled from Hudson River, Delaware River, Chesapeake Bay, North Carolina, and South Carolina. Analyses indicated clear population structure with significant genetic differentiation between all regions. Global multilocus F-ST was estimated at 0.028 (P < 0.001). Population structure followed an isolation-by-distance model and temporal sampling indicated a stable population structure more than 2 years at all locations. Significant structure was absent within Hudson River, whereas weak but significant genetic differences were observed between northern and southern samples in Chesapeake Bay. The largest and smallest effective striped bass population sizes were found in Chesapeake Bay and South Carolina, respectively. Coalescence analysis indicated that the highest historical gene flow has been between Chesapeake Bay and Hudson River populations, and that exchange has not been unidirectional. Bayesian analysis of contemporary migration indicated that Chesapeake Bay serves as a major source of migrants for Atlantic coastal regions from Albemarle Sound northward. In addition to examining population genetic structure, the data acquired during this project were capable of serving as a baseline for assigning fish with unknown origin to source region.

Corrected Numbers For Fish On Red List, Bruce B. Collette, Beth Polidoro, Kent Carpenter
Biological Sciences Faculty Publications
(First paragraph) Kelly Swing gives inaccurate numbers for marine fish species on the International Union for Conservation of Nature (IUCN) Red List of Threatened Species. He also mistakenly conflates the scientific process of species assessment for the Red List with the separate political process of IUCN member voting (Nature 494, 314; 2013).

Texas A&M University, Corpus Christi
What Is Known About Species Richness And Distribution On The Outer-Shelf South Texas Banks?, Harriet L. Nash, Sharon J. Furiness, John W. Tunnell Jr.
Gulf and Caribbean Research
The outer-shelf South Texas Banks, also known as the snapper banks, are known by fishermen to be excellent fishing grounds. However, few scientific studies have been conducted to describe the ecology of these uncommon but distinctive habitats. This paper describes results of a literature review and an assessment to determine what is known about the biota of the South Texas Banks and to assist in developing renewed interest and focus on these topographic highs. The outer-shelf South Texas Banks include relict coralgal reefs and relict barrier islands, and we also include data for a nearshore site, which is geographically and …

Assessment Of Seagrass Floral Community Structure From Two Caribbean Marine Protected Areas, Paul A.X. Bologna, Anthony J. Suleski
Gulf and Caribbean Research
Seagrass communities represent spatially complex and biomass producing systems comprised of intermixed seagrass and algal species. We investigated shallow water communities from two Marine Protected Areas (MPAs) in the Caribbean: St. John, United States Virgin Islands and Cayos Cochinos, Honduras. St. John sites (4) lie within the Virgin Islands National Park and the Coral Reef National Monument and are designated within an UNESCO Biosphere Reserve. Honduran sites (4) lie within the designated Marine National Monument. Our results indicate that both MPAs were dominated by Thalassia testudinum with spatial coverage and shoot density significantly greater in Honduras. Many sites also showed …

Depuration Of Macondo (Mc-252) Oil Found In Heterotrophic Scleractinian Corals (Tubastrea Coccinea And Tubastrea Micranthus) On Offshore Oil/Gas Platforms In The Gulf, Steve R. Kolian, Scott Porter, Paul W. Sammarco, Edwin W. Cake Jr.
Gulf and Caribbean Research
The impetus for this study began on 8 May 2011, when we noted sporadic mortality of colonies of orange—cup corals, Tubastrea coccinea (Lesson, 1829), and green sun corals, Tubastrea micranthus (Ehrenberg, 1834; Cnidaria, Anthozoa, Scleractinia) among colonies of coral that appeared to be in good health at the GI 90 block platforms. Colonies of T. coccinea which appeared to be healthy displayed markedly less tissue regression and were bright orange in color. The morbid polyps were dark brown or black. The corals were collected, transported to the laboratory, and segregated; healthy—appearing corals were placed in quarantine tanks. After 12 h …

A Preliminary Examination Of An In Situ Dual Dye Approach To Measuring Light Fluxes In Lotic Systems, Elizabeth C. Minor, Elizabeth James, Jay A. Austin, Veronica Nelson, Ryan Lusk, Kenneth Mopper
Chemistry & Biochemistry Faculty Publications
Light is a critical parameter in aquatic ecosystems, affecting primary production and in situ photochemistry. However, measuring light exposure for suspended particles or dissolved components in a dynamic water column can be challenging with existing Eulerian approaches. Here, we assess the simultaneous deployment of two dyes differing in photolability (rhodamine WT and fluorescein) as a Lagrangian measure of sunlight exposure in a lotic system. Fluorescein is sensitive to light exposure; rhodamine WT is relatively photostable. We examined dye fluorescence at various pH, salinity, and temperature conditions. We also tested dye photolability as a function of pH and wavelength range. In …

Occurrence Of An Intersexual Blacktip Shark In The Northern Gulf Of Mexico, With Notes On The Standardization Of Classifications For This Condition In Elasmobranchs, Jill M. Hendon, David M. Koester, Eric R. Hoffmayer, William B. Driggers Iii, Angela M. Cicia
Faculty Publications
An intersexual Blacktip Shark Carcharhinus limbatus with a testis, immature female reproductive tracts (embedded), and claspers was caught in the Gulf of Mexico. Histology of the single gonad revealed that all stages of spermatogenesis were occurring; however, the absence of ovaries and a male duct system suggests that neither sex would have been functional in this individual. Intersexuality has been reported in 17 families and 36 species of elasmobranchs. The degree to which the different sexes are present in a given individual is often difficult to categorize by normal hermaphroditic standards, as this is typically an anomalous presentation in elasmobranchs. …

Consumptive And Non-Consumptive Effects Of Predatory Fishes On Lobster In Southern Maine, Erin B. Wilkinson
All Theses And Dissertations
The American lobster, Homarus americanus, is an important consumer in the Gulf of Maine benthic community and supports the most valuable fishery in New England. Many fish predators that feed on juvenile lobster are found in the Gulf of Maine, but their abundance has varied over the previous decades. For example, striped bass, Morone saxatilis, have recovered from near extinction to become a viable recreational fishery on the east coast, and previous work examining the gut contents of striped bass found that juvenile lobsters were a large component of their diet during the summer in Massachusetts. However, striped …
