Isotope Ratio Studies Of Marine Mammals In Prince William Sound, Donald M. Schell, Amy Hirons

Marine & Environmental Sciences Faculty Reports

This project consists of two components: (1) provision of analytical services for the stable isotope ratio investigations associated with Exxon Valdez oil spill projects, and (2) an investigation of food web relationships and trophic interactions of harbor seals and other top consumers of Prince William Sound (PWS). Through the use of harbor seal tissues collected from native harvested animals and tagging programs, seasonal and migrational information has been obtained with regard to prey utilization and trophic status at differing locations within the sound and the adjacent Gulf of Alaska. Preliminary results indicate that within PWS, harbor seals fall at the …

Barium Chronologies From South Florida Reef Corals - Environmental Implications, D. Anderegg, Richard E. Dodge, Peter K. Swart, L. Fisher

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

Benthic algal blooms (e.g., Codium isthmocladum) have become increasingly common on reefs and hardgrounds of Southeast Florida. The contribution from possible responsible nutrient sources, including natural upwelling and local pollution, has not been quantified. In an attempt to differentiate each potential source, lattice-bound barium concentrations in the skeletons of two common Southeast Florida stony coral species (Montastraea faveolata and Solenastrea bournoni) were measured by isotope dilution inductively coupled mass spectrometry (ICP/MS). Specimens were collected offshore between 26˚01'-57'N at shallow (10m) and deep (20m) reefs. X-rays of skeletal slabs revealed annual density bands which guided annual and subannual …

Species Composition, Abundance, And Vertical Distribution Of The Stomiid (Pisces: Stomiiformes) Fish Assemblage Of The Gulf Of Mexico, Tracey Sutton, T. L. Hopkins

Marine & Environmental Sciences Faculty Articles

Species composition, abundance, and vertical distribution of the stomiid fish assemblage were investigated in the eastern Gulf of Mexico, a low-latitude, oligotrophic oceanic ecosystem. Seventy-two described species, representing 18 genera, and one undescribed species were identified from 1155 trawl samples. With an additional 10 species reported elsewhere, the stomiid species number now known equals 83, making the Stomiidae the most diverse fish family in the Gulf of Mexico. The assemblage was dominated by three species,Photostomias guernei, Chauliodus sloani and Stomias affinis. These species, as well as four other common species, exhibited an asynchronous diel vertical migration pattern (450–900 …

Observation Of Spatial Variability Of Diurnal Thermocline And Rain-Formed Halocline In The Western Pacific Warm Pool, Alexander Soloviev, Roger Lukas

Marine & Environmental Sciences Faculty Articles

High-resolution measurements of temperature and salinity were made in the near-surface layer of the ocean during the Tropical Oceans-Global Atmosphere Coupled Ocean-Atmosphere Response Experiment, using probes mounted on the bow of the R/V Moana Wave. Because of surface waves and pitching of the vessel, the bow probes profiled the near-surface layer of the ocean within depths of 0–4.0 m. In the near-surface layer of the ocean in the western Pacific warm pool, strong variability of temperature and salinity produced by diurnal heating and/or rain was often observed. The contoured density field revealed cases of pronounced spatial variability. The shallow …

Corals Of The South-West Indian Ocean Iv. The Hard Coral Family Faviidae Gregory, 1900 (Scleractinia: Faviina), Bernhard Riegl

Marine & Environmental Sciences Faculty Reports

This annotated check-list deals with the scleractinian coral family Faviidae in subtropical south-east Africa (the African mainland coast south of the Tropic of Capricorn). Material from the atoll Bassas da India in the Mozambique channel was included. Most species are of wide Indo-Pacific distribution. The faviid fauna of Mozambique was richer (28 species) than the South African fauna (21 species). The fauna of Bassas da India was similar to that on the African mainland coast with four additional species. South-east Africa has a moderately rich faviid fauna compared with other areas in the Indo-Pacific region. Field and laboratory characteristics are …

A 240-Year Stable Oxygen And Carbon Isotopic Record In A Coral From South Florida: Implications For The Prediction Of Precipitation In Southern Florida, Peter Koenraad Swart, Richard E. Dodge, Harold J. Hudson

Marine & Environmental Sciences Faculty Articles

This study reports on the δ¹⁸O and δ¹³C composition of the skeleton from a 240-year-old specimen of Montastraea faveolata growing in Biscayne National Park, South Florida. Annual variations in the δ¹⁸O of the skeleton deposited during the summer months show a bimodal correlation with summer rainfall. During wetter years, the δ¹⁸O of the coral skeleton and the amount of precipitation during the summer months are inversely correlated (r = -0. 7) reflecting dilution of the seawater by meteoric water lower in δ¹⁸O. During years in which summer rainfall is less …

Ecology And Behavior Of Maxillipius Commensalis, A Gorgonophile Amphipod From Madang, Papua New Guinea (Crustacea: Amphipoda: Maxillipiidae), James Darwin Thomas

Marine & Environmental Sciences Faculty Articles

Maxillipius commensalis Lowry, is reported as an ectocommensal on arborescent gorgonaceans from coral reefs at Madang, Papua New Guinea. The family is reviewed and the male of this species is described. In-situ behavior studies show the amphipods to crowd close together in large numbers on one side of a gorgonian stalk. The terminal articles of the sixth pereopods are greatly elongated and whip-like and are waved at the sides in a circular motion, possibly facilitating spacing or feeding. When disturbed, the amphipods react en masse as a coherent group rather than as individuals.

Diet And Seasonal Feeding Habits Of The Yellow Stingray, Urolophus Jamaicensis, T. Patrick Quinn

HCNSO Student Theses and Dissertations

Urolophus jamaicensis, the yellow stingray, is a common elasmobranch found on and around the coral reefs off Florida's southeastern coast. Its diet consists of polychaetes, crustaceans, nemerteans, sipunculids, nematodes, and chaetognaths with polychaetes and crustaceans comprising almost 67% of the stomach contents by volume. There does not appear to be any diet preference between the male and females stingrays. The seasonal changes in diet preference are limited to an increase in the proportion of polychaetes found in the stomach during spring when compared to fall.

Regulation Of Beta-Glucosidase In Marine Bacteria, Dennis Stetter

HCNSO Student Theses and Dissertations

The following is a study of the regulation of production of a catabolic enzyme, beta-glucosidase, by isolated strains of marine bacteria. Catabolic enzymes transform organic matter to monosaccharides which are utilized as an energy source for growth by bacteria. The bacterial strains were isolated from the Gulf Stream off the coast of Florida, as well as from particulate matter collected from waters adjacent to the Florida coast.

The first section describes the preparation of a liquid medium using sterile saltwater supplemented with inorganic nutrients and a carbohydrate component. This medium allowed growth of marine bacteria under carbohydrate-limiting conditions. A solid …

Phosphorous Limitation And Trophic Status In Limestone Quarry Lakes, Dade County, Fl, Isaac Peter Chase

HCNSO Student Theses and Dissertations

While limestone quarry lakes have existed in South Florida for many years, only recently have they received serious scrutiny. A thorough understanding of the trophic dynamics of these lakes has yet to be achieved. Questions have arisen as to the value of these lakes for such purposes as water reclamation, conservation, and recreational use. The purpose of this study was twofold, 1) to investigate the trophic processes within these lakes with special regard to phosphorus limitation, and 2) to help provide a better understanding of the linmology of these lakes, specifically through the quantification and identification of the invertebrate life …

Final Report Biological Monitoring Of The Hollywood-Hallandale Beach Renourishment, Richard Dodge, Walter Goldberg, Charles Messing, Steven C. Hess

Marine & Environmental Sciences Faculty Reports

A four-year study was undertaken to survey Broward County, Florida (southeast Florida) coral communities and infaunal marine biota in relation to possible effects from the Hollywood- Hallandale Beach renourishment project. Beach restoration involves dredging sand from offshore deposits and placing it on eroded beaches, activities which may cause sedimentation and turbidity. Coral reefs were assessed using transect and quadrat surveys at a total of 15 stations, unevenly distributed between dredging impact (n=9) and control (n=6) areas to characterize and quantify populations of sponges, gorgonians, scleractinian corals, as well as other less well represented groups. In addition, the infauna of sand …

Molecular Evolution Of Numt, A Recent Transfer And Tandem Amplification Of Mitochondrial Dna Into The Nuclear Genome Of The Domestic Cat (Felis Catus), Jose V. Lopez

Oceanography Faculty Theses and Dissertations

Mitochondrial DNA (mtDNA) are functional cytoplasmic chromosomes, tracing origins to a symbiotic infection of eukaryotic cells by bacterial progenitors. As prescribed by the Serial Endosymbiosis Theory, symbionts have gradually transferred their genes to the nuclear genome that enable functional interaction. In this dissertation, a 7.9 kb transposition of a typically 17.0 kb mitochondrial genome to a specific chromosomal position in the domestic cat is reported. The integrated mtDNA has amplified about 38-76 times and now occurs as a "macrosatellite"-like tandem repeat with multiple length alleles resolved by pulse field gel electrophoresis (PFGE) segregating in cat populations. To examine the tempo …

Tissue Damage In Scleractinian And Alcyonacean Corals Due To Experimental Exposure To Sedimentation, Bernhard Riegl, Jonathan P. Bloomer

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

Four South African scleractinian corals (Favia favus, Favites pentagona, Platygyra daedalea and Gyrosmilia interrupta) and four alcyonacean corals (Lobophytum depressum, Lobophytum venustum, Sinularia dura and Sinularia leptoclados) were experimentally exposed to high sedimentation conditions in the laboratory during a period of six weeks. Experimental sedimentation corresponded to the highest measured sedimentation levels on South African coral reefs, being 200 mg cm-2h-l. Corals were monitored for tissue necroses and bleaching during the course of the experiment and histological sections were prepared after the termination of the experiment. During the experiment, tissue necroses appeared earlier and more frequently in alcyonacea than in …

Is Coral Community Structure Linked To Damage Susceptibility? A Case Study From South Africa, Bernhard Riegl, Peter A. Cook

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

Africa's southernmost coral communities are situated in northern Natal, South Africa (27°50' S), within the Maputaland and St. Lucia Marine Reserves. Growing concern about the possible impact of recreational acti vities on the health of the coral ecosystem prompted the present study on the structure and health of the reefs. Coral community studies by means of line transects identified three basic coral community types, which correlated with the geomorphology of the sandstone outcrops on which corals grew. 1) Fossil dunes were dominated by alcyonacea in depths between 8 and 24 m. 2) Flat outcrops between 18 and 24 m depth …
