Case 3270: Isometrinae Clark, 1917 (Ecinodermata, Crinoidea): Proposed Emendation Of Spelling To Isometrainae To Remove Homonymy With Isometrinae Kraepelin, 1891 (Arachnida, Scorpiones), Victor Fet, Charles G. Messing

Marine & Environmental Sciences Faculty Articles

The purpose of this application, under Articles 55 and 29 of the Code, is to remove the homonymy between the crinoid subfamily name ISOMETRINAE Clark, 1917 (type genus Isometra Clark, 1908; family ANTEDONIDAE) and the scorpion subfamily name ISOMETRINAE Kraepelin, 1891 (type genus Isometrus Ehrenberg in Hemprich & Ehrenberg, 1828; family BUTHIDAE). It is proposed that the entire generic name of Isometra should be adopted as the stem, so that the correct spelling of the crinoid subfamily will become ISOMETRAINAE Clark, 1917.

Age, Growth And The Annual Cycles Of Lipogenesis And Reproduction Of Acanthurus Bahianus In Southeastern Florida, Stacy M. Wolfe

HCNSO Student Theses and Dissertations

The ocean surgeon, Acanthurus bahianus, is a coral reef fish inhabiting the tropical and subtropical waters of the western Atlantic, including southeastern Florida. This study was a 23-month analysis of the reproductive cycle correlated with the annual build up and depletion of fat reserves in the fish. In addition, an age and growth analysis of this species was conducted. A total of 507 fish were analyzed for length, weight, gonad weight and fat body weight. 478 were aged by microscopic examination of the transverse section of the sagittae otolith. The von Bertalannfy growth equation was used to determine length at …

Coastal Observatory Investigates Energetic Current Oscillations On Southeast Florida Shelf, Alexander Soloviev, Rebekah J. Walker, Robert H. Weisberg, Mark E. Luther

Marine & Environmental Sciences Faculty Articles

Coastal circulation along the southeast Florida shelf is strongly related to the dynamics of the Florida Current. The current follows the steep bottom terrain along the shelf break separating the deep ocean from the coastal zone (Figure 1 a, b). Energetic and complex flow regimes arise along the current's western edge, causing transient features such as sub-meso-scale eddies [Lee and Mayer, 1977; Shay et al., 2000] and energetic internal oscillations [Mooers, 1975; Soloviev et al., 2003], which affect mixing between the shelf and deeper ocean waters. Understanding of these regimes is important for modeling and prediction of the …

Who Is Eating Most Of The Zooplankton In The Oceanic Gulf Of Mexico? The Impact Of Mesopelagic Fishes, Tracey Sutton, Scott E. Burghart

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

Deep-sea pelagic fishes are the most abundant vertebrates on Earth, yet their role in the overall economy of these is poorly known. Low latitude oligotrophic regimes, typified by the eastern Gulf of Mexico, constitute most of the world ocean and consequently support the largest global ecosystems. Thus, we have little information on the trophic role of most of Earth's vertebrates. To address this, the diets of an entire midwater fish assemblage (164 species, constituting > 99% of assemblage numbers) were analyzed to assess feeding guilds and predation impact. Zooplanktivory was the dominant feeding mode (80% of prey biomass taken), followed by …

A Rapid Assessment Of Coral Reefs Near Hopetown, Abaco Islands, Bahamas (Stony Corals And Algae), Joshua Feingold, Susan L. Thornton, Kenneth W. Banks, Nancy J. Gasman, David S. Gilliam, Pamela Fletcher, Christian L. Avila

Marine & Environmental Sciences Faculty Articles

Coral reefs at 13 sites ranging in depth from 1-16 m near Hopetown, Abaco Islands, Bahamas were surveyed utilizing the Atlantic and Gulf Rapid Reef Assessment (AGRRA) benthos protocol. A total of 35 species of scleractinian corals and 2 species of calcareous hydrocorals were observed. The overall coral cover averaged just over 14%. Among corals that were at least 10 cm in diameter, small colonies (< 40 cm diameter) predominated in all sites except for the Fowl Cay pinnacles where 68% were larger than 60 cm in diameter. Large colonies (> 40 cm diameter) were also found in the Lynyard Cay spur-and-groove formations and the Sandy Cay fore reef. Zero-4% of the colonies were affected by disease. Total (recent + old) partial-colony mortality ranged from …

Phytoplankton Response To Intrusions Of Slope Water On The West Florida Shelf: Models And Observations, John J. Walsh, Robert H. Weisberg, Dwight A. Dieterle, Ruoying He, Brian P. Darrow, Jason K. Jolliff, Kristen M. Lester, Gabriel A. Vargo, Gary J. Kirkpatrick, Kent A. Fanning, Tracey Sutton, Ann E. Jochens, Douglas C. Biggs, Bisman Nababan, Chuanmin Hu, Frank E. Muller-Karger

Marine & Environmental Sciences Faculty Articles

Previous hypotheses had suggested that upwelled intrusions of nutrient-rich Gulf of Mexico slope water onto the West Florida Shelf (WFS) led to formation of red tides of Karenia brevis. However, coupled biophysical models of (1) wind- and buoyancy-driven circulation, (2) three phytoplankton groups (diatoms, K. brevis, and microflagellates), (3) these slope water supplies of nitrate and silicate, and (4) selective grazing stress by copepods and protozoans found that diatoms won in one 1998 case of no light limitation by colored dissolved organic matter (CDOM). The diatoms lost to K. brevis during another CDOM case of the models. In …

Energetic Baroclinic Super-Tidal Oscillations On The Southeast Florida Shelf, Alexander Soloviev, Mark E. Luther, Robert H. Weisberg

Marine & Environmental Sciences Faculty Articles

Historical and recent data reveal a very energetic regime on the shelf off southeast Florida. In addition to spin off eddies, large-amplitude tidal velocity fluctuations with amplitudes exceeding 0.5 ms⁻¹ are observed. Recent exploratory measurements conducted as a part of the South Florida Ocean Measurement Center (SFOMC) show that the time scale of these oscillations is about 10 hrs. This period does not coincide either with the inertial period (27 Hrs) or with the semidiurnal M₂ (12.42 hrs) or S₂ (12 hrs) tidal constituents. In addition, these internal oscillations appear to be modulated seasonally. A possible explanation …

Biology And Ecologyof Epigean Crayfish That Inhabit Everglades Environments Procambarus Alleni (Faxon) And Procambarus Fallax (Hagen), Peggy G. Vanarman

HCNSO Student Theses and Dissertations

Two species of epigean crayfish, Procambarus alleni (the Everglades crayfish) and Procambarus fallax (slough crayfish), may be keystone species that inhabit wetlands in south Florida and the Everglades. Recent field studies showed that although these two species occur in sympatric and syntopic distribution, Everglades crayfish prefer shallow water and short hydroperiod conditions, whereas slough crayfish prefer areas that are more permanently flooded (Hendrix 2000). Slough crayfish have invaded some areas within the range occupied by Everglades crayfish, and may be the more successful competitor. Because of their critical role throughout the trophic structure of Everglades wetlands, shifts in relative abundance …

Habitat Utilization By Bottlenose Dolphins (Tursiops Truncatus) In Biscayne Bay, Florida, Christine A. Hudak

HCNSO Student Theses and Dissertations

Bottlenose dolphins (Tursiops truncatus) exhibit variable distribution patterns, depending upon their geographic location. Habitat utilization patterns in Biscayne Bay, Florida, were examined using the Biscayne Bay Bottlenose Dolphin Photo-ID database obtained from the National Oceanic and Atmospheric Administration (NOAA) Southeast Fisheries Science Center (SEFSC) Miami Laboratory. Habitat coverages in Biscayne Bay were obtained from the Atlas of Marine Resources Version 1.3B CD and the Biscayne Bay National Park CD. Dolphin sightings were overlaid on the habitat coverages using GIS Arcview software.

The effects of habitat, season, behavior, zone (sectioned area of Biscayne Bay), and depth on patterns …

Habitat Standardization Of Cpue Indices: Research Needs, C. Phillip Goodyear, David Die, David W. Kerstetter, Donald Olson, Eric Prince, Gerald P. Scott

Marine & Environmental Sciences Faculty Reports

Habitat standardization for billfish CPUE offers a potentially useful alternative to the statistical procedures used in the past. However, most of the assumptions of the current habitatstandardization methodology remain untested and some are not consistent with current knowledge about the behavior of billfish. This paper outlines research required to ensure the methods for habitat standardization produce robust estimates of CPUE.

Habitat Preferences Of Istiophorid Billfishes In The Western North Atlantic: Applicability Of Archival Tag Data To Habitat-Based Stock Assessment Methodologies, John E. Graves, David W. Kerstetter, Brian E. Luckhurst, Eric D. Prince

Marine & Environmental Sciences Faculty Reports

The Japanese pelagic longline fishery, which has a broad temporal and spatial coverage in the Atlantic Ocean, provides an important time series used in assessments of istiophorid billfishes. Past assessments of Atlantic blue marlin and white marlin by the ICCAT SCRS indicate a pronounced decrease in stock abundance of both species over the past fifty years. The current biomass of the white marlin is estimated to be 15% of that necessary for maximum sustainable yield (BMSY), while blue marlin are estimated to be at 0.4 BMSY. Over the past fifty years Japanese pelagic longline fishing operations have moved from shallow …

Status Of Coral Reefs Of Little Cayman, Grand Cayman And Cayman Brac, British West Indies, In 1999 And 2000 (Part 1: Stony Corals And Algae), Carrie Manfrino, Bernhard Riegl, Jerome L. Hall, Robert Graifman

Marine & Environmental Sciences Faculty Articles

A benthic assessment of the isolated Cayman Islands was completed at 42 sites. Major changes in the reef community structure were documented by comparison with earlier studies. Acropora palmata and A. cervicornis, once abundant as shallow framework builders, were uncommon. Diseased stony corals were seen in >90% of the study sites, with the highest averages in Little Cayman, especially at Bloody Bay which is one of the most highly regulated marine parks in the Cayman Islands. The Montastraea annularis species complex accounted for two-thirds of the diseased corals which, along with other massive species, were affected largely by white-plague …

Assessment Of The Coral Reefs Of The Turks And Caicos Islands (Part 1: Stony Corals And Algae), Bernhard Riegl, Carrie Manfrino, Casey Hermoyian, Marilyn Brandt, Kaho Hoshino

Marine & Environmental Sciences Faculty Articles

Major constituents of the benthic reef community (stony corals, algae) were assessed in 28 reefs on the Caicos, Turks and Mouchoir Banks. Living stony coral cover ranged from 8-28%, averaging 18% overall. Montastraea annularis and M. faveolata of “intermediate” sizes (cm) dominated all examined reefs. Acropora palmata and A. cervicornis were scarce. The most frequently recruiting scleractinians were Porites astreoides and Agaricia agaricites; Montastraea recruits were uncommon. Old partial-colony mortality (overall mean = 23%) was greater than recent partial-colony mortality (mean = 3%). Crustose coralline algae and turf algae were generally more abundant than macroalgae. Mouchoir Bank, with the …

Histidine-Decarboxylase Knockout Mice Show Deficient Nonreinforced Episodic Object Memory, Improved Negatively Reinforced Water-Maze Performance, And Increased Neo- And Ventro-Striatal Dopamine Turnover, Ekrem Dere, Maria A. De Souza-Silva, Bianca Topic, Richard E. Spieler, Helmut L. Haas, Joseph P. Huston

Marine & Environmental Sciences Faculty Articles

The brain's histaminergic system has been implicated in hippocampal synaptic plasticity, learning, and memory, as well as brain reward and reinforcement. Our past pharmacological and lesion studies indicated that the brain's histamine system exerts inhibitory effects on the brain's reinforcement respective reward system reciprocal to mesolimbic dopamine systems, thereby modulating learning and memory performance. Given the close functional relationship between brain reinforcement and memory processes, the total disruption of brain histamine synthesis via genetic disruption of its synthesizing enzyme, histidine decarboxylase (HDC), in the mouse might have differential effects on learning dependent on the task-inherent reinforcement contingencies. Here, we investigated …

Assessment Of The Coral Reefs Of The Turks And Caicos Islands (Part 2: Fish Communities), Kaho Hoshino, Marilyn Brandt, Carrie Manfrino, Bernhard Riegl, Sascha C. C. Steiner

Marine & Environmental Sciences Faculty Articles

Ecologically and commercially significant coral reef fishes were surveyed at 28 sites in the Turks and Caicos Islands during August 1999. Our results constitute the first quantitative census of these fishes and can serve as baseline information for subsequent studies. Their density and size generally were highest off West Caicos and lowest in Mouchoir Bank. Herbivore density overall showed no correlation with macroalgal index (a proxy for biomass) or live stony coral cover, but surgeonfish density was positively correlated with macroalgal index. Species richness of these select fishes was positively correlated with the species richness of stony corals that were …

Growth And Survivorship Of Meandrina Meandrites And Montastrea Cavernosa Transplants To An Artificial Reef Environment, And The Effectiveness Of Plugging Core Holes In Transplant Donor Colonies, Elizabeth Glynn Fahy

HCNSO Student Theses and Dissertations

The growth and survivorship of two species of scleractinian coral transplants, Meandrina meandrites and Montastrea cavernosa, were investigated. Identically sized replicate transplants were obtained from the second reef, off Dania Beach, using a hydraulic drill fitted with a 4” core barrel. The transplants were fixed to Reef Ball™ substrates using an adhesive marine epoxy. Drill holes in the donor corals (core holes) were filled with concrete plugs to prevent the detrimental effects of bioeroders. Control corals, of comparable size to both the donor colonies and the transplant corals, were selected for comparison. The transplant corals, donor corals, and controls …
