Habitat Use By Juvenile Gag, Mycteroperca Microlepis (Pisces: Serranidae), In Subtropical Charlotte Harbor, Florida (Usa), J. Patrick Casey, Gregg R. Poulakis, Philip W. Stevens

Gulf and Caribbean Research

Estuaries play a key role in the juvenile stage of gag (Myeteroperca microlepis). The use of estuarine habitats by juvenlle gag has been examined in temperate estuaries, which are at the northern limits of the range of this species, but the importance of subtropical estuaries during the early life history of this species has not been studied extensively. Gag were collected in subtropical Charlotte Harbor, Florida, during routine monthiy sampling from January 1996 to Decemher 2002. Juvenlle gag were collected using a 21.3-m seine, a 183-m haul seine, and a 183-m purse seine. A total of 738 individuals …


Strategic Investments In Large Pelagic Research, Nancy B. Thompson, Eric D. Prince Jan 2007

Strategic Investments In Large Pelagic Research, Nancy B. Thompson, Eric D. Prince

Gulf and Caribbean Research

The Southeast Fisheries Science Center (SEFSC) of the US NOAA Fisheries provides much of the US science advice for the management of Highly Migratory Species (HMS) in the Atlantic, Gulf of Mexico and US Caribbean Sea. These stocks include the tunas, sharks, billfishes and swordfish all of which are targeted either commercially or recreationally or both in US waters. These species are managed internationally through membership to the International Commission for the Conservation of Atlantic Tunas (ICCAT); however, while the US is an ICCAT member, few Caribbean nations are members.


Observations Of A Feeding Aggregation Of Whale Sharks, Rhincodon Typus, In The North Central Gulf Of Mexico, Eric R. Hoffmayer, James S. Franks, William B. Driggers Iii, Kenneth J. Oswald, Joseph M. Quattro Jan 2007

Observations Of A Feeding Aggregation Of Whale Sharks, Rhincodon Typus, In The North Central Gulf Of Mexico, Eric R. Hoffmayer, James S. Franks, William B. Driggers Iii, Kenneth J. Oswald, Joseph M. Quattro

Gulf and Caribbean Research

On 26 June 2006 an aggregation of 16 whale sharks was observed for a period of 4 hr in the north central Gulf of Mexico (GOM). The sharks remained within an area about 1.0 km2 in size and continuously ram filter fed at the surface. Visual analysis of a plankton sample collected from the study site revealed the presence of copious amounts of fish eggs in mid-embryonic development and a minor amount of other zooplankton. A second plankton sample (control) collected about 3.5 km from the study site in an area where no whale sharks were present contained few …


Nocturnal Depth Distribution Of Western North Atlantic Swordfish (Xiphias Gladius, Linnaeus, 1758) In Relation To Lunar Illumination, Joshua K. Loefer, George R. Sedberry, John C. Mcgovern Jan 2007

Nocturnal Depth Distribution Of Western North Atlantic Swordfish (Xiphias Gladius, Linnaeus, 1758) In Relation To Lunar Illumination, Joshua K. Loefer, George R. Sedberry, John C. Mcgovern

Gulf and Caribbean Research

Swordfish are known to undergo large diel vertical movements from surface waters at night to > 300 m depth during the day. Evidence presented over the past several deeades suggests the lunar cycle affects these vertical migrations. This study collected data concurrently from 7 swordfish throughout 3 consecutive lunar cycles using pop-up satellite archival tags. All individuals demonstrated an inverse relationship between recorded nocturnal depths and lunar illumination.


Genetic Analysis Of Blue Marlin (Makaira Nigricans) Stock Structure In The Atlantic Ocean, Jan R. Mcdowell, Jeanette E.L. Carlsson, John E. Graves Jan 2007

Genetic Analysis Of Blue Marlin (Makaira Nigricans) Stock Structure In The Atlantic Ocean, Jan R. Mcdowell, Jeanette E.L. Carlsson, John E. Graves

Gulf and Caribbean Research

The genetic basis of stock structure of blue marlin (Makaira nigricans Lacepède 1802) in the Atlantic ocean was inferred from analyses of mitochondrial control region sequences. Blue marlin were collected in 1998 from 4 major geographic locations: western North Atlantic, Caribbean Sea, western South Atlantic and eastern Atlantic. Haplotype diversity (h) ranged from 0.99-1.0 and nucleotide sequence diversity (π) ranged from 0.11-0.13 within samples indicating that the control region harbors a significant amount of genetic variation. However, no significant differences were found in the spatial partitioning of genetic variation among the 4 collections; all pairwise ϕST …


Patterns Of Vertical Habitat Use By Atlantic Blue Marlin (Makaira Nigricans) In The Gulf Of Mexico, Richard T. Kraus, Jay R. Rooker Jan 2007

Patterns Of Vertical Habitat Use By Atlantic Blue Marlin (Makaira Nigricans) In The Gulf Of Mexico, Richard T. Kraus, Jay R. Rooker

Gulf and Caribbean Research

We examined data from pop-up archival transmitting (PAT) tags (n = 18) to characterize aspects of vertical habitat use by blue marlin (Makaira nigricans) from the Gulf of Mexico (GOM). Two of these tags were recovered and provided fine-scale information about diving patterns and the relationship between time at depth and temperature. Similar to previous studies, blue marlin in the GOM spent most of their time at the surface and at temperatures within 3° C of surface temperatures. Time at depth was multimodal and the magnitude of the smaller modes was dependent upon the strength and depth …


Large Pelagics In The Southern Section Of The Seaflower Marine Protected Area, San Andres Archipelago, Colombia: A Fishery In Expansion, Erick Castro, Heins Bent, Carlos Ballesteros, Martha Prada Jan 2007

Large Pelagics In The Southern Section Of The Seaflower Marine Protected Area, San Andres Archipelago, Colombia: A Fishery In Expansion, Erick Castro, Heins Bent, Carlos Ballesteros, Martha Prada

Gulf and Caribbean Research

Isolated and sparse reef atolls comprising the southern section of the Seaflower MPA have been traditionally exploited by artisanal fishers using handlines. These practices have severely depleted the demersal fish stock and now fishers have shifted their efforts to the pelagic stock. The pelagic fishery included the extraction of more than 25 species, with Thunnus atlanticus, Acanthocybium solandri, Coryphaena hippurus, and Katsuwonus pelamis being the most common. Three years of fishery-dependent data (2004–2006) were used to describe traditional fishing methods and techniques, and to document, for the first time, a declining trend in the large pelagic stock. …

Identification Of A 17-Nucleotide Splicing Enhancer In Hpv-16 L1 That Counteracts The Effect Of Multiple Hnrnp A1-Binding Splicing Silencers, Ziaomin Zhao, Joanna Fay, Stefan Schwartz, Helen Lambkin

Articles

Human papillomavirus type 16 (HPV-16) infections can in rare cases persist and cause lesions that may progress to cervical cancer. Cells in the lesions are not permissive for virus production, nor are cervical cancer cells. The intracellular environment is such that it prevents production of the highly immunogenic, viral structural proteins L1 and L2. One may speculate that inhibition of L1 and L2 expression is a prerequisite for persistence and cancer progression.We have therefore investigated how expression of HPV-16 L1 is regulated.We found that the only splice site in the HPV-16 late region, which is used to produce L1 mRNAs, …


Mutagenesis Of The Catalytic Triad Of Tissue Transglutaminase Abrogates Coeliac Disease Serum Iga Autoantibody Binding, Greg Byrne, Fergus Ryan, John Jackson, Con Feighery, Jacinta Kelly Jan 2007

Mutagenesis Of The Catalytic Triad Of Tissue Transglutaminase Abrogates Coeliac Disease Serum Iga Autoantibody Binding, Greg Byrne, Fergus Ryan, John Jackson, Con Feighery, Jacinta Kelly

Articles

Background and aims: Tissue transglutaminase (tTG) is an autoantigen in coeliac disease and the related disorder, dermatitis herpetiformis. The detection of autoantibodies directed against tTG is a highly specific marker of coeliac disease; however, it is unclear if there is a role for these autoantibodies in the disease process. The aim of this study was to investigate whether the catalytic triad of tTG is targeted by coeliac disease autoantibodies. Methods: A full-length wild-type recombinant tTG and a novel site-directed mutagenic variant lacking the catalytic triad were produced in Escherichia coli. Serum samples from 61 biopsy-proven coeliac disease and 10 dermatitis …

Reflections: A Theatrical Journey Into The Lives Of Adolescent Girls, Leah Page Jan 2007

Reflections: A Theatrical Journey Into The Lives Of Adolescent Girls, Leah Page

Electronic Theses and Dissertations

Adolescence is a difficult time for young women. Their bodies are changing and they are being asked to conform to a new set of feminine standards if they are to be accepted (Pipher 39). Studies have found that girls experience a decrease in self-esteem during this time. They are less likely to speak their minds openly and honestly, which can lead to depression and a feeling of falseness. As young women attempt to comprehend this turbulent time in their lives, they often find strength through positive relationships with others as well as from their own knowledge and self-awareness. Reflections is …


Tree Calls Of Three Treefrogs (Hyla Femoralis, H. Gratiosa, And H. Squirella): Analysis Of Environmental, Behavioral, And Acoustic Characteristics, Kristine Schad Jan 2007

Tree Calls Of Three Treefrogs (Hyla Femoralis, H. Gratiosa, And H. Squirella): Analysis Of Environmental, Behavioral, And Acoustic Characteristics, Kristine Schad

Electronic Theses and Dissertations

Male frogs typically call near water at dusk to attract females for breeding. During the breeding season, male treefrogs also emit diurnal "tree calls" or "rain calls" from the tops of trees. Very little is known about tree calls, although many treefrogs use them. Tree calls may be used to attract females, deter males or be triggered by weather conditions favorable for breeding: high temperature and relative humidity, and a drop in barometric pressure. As dusk approaches, male treefrogs continue tree calls from lower in the trees, and if conditions are favorable, jump to the ground and travel to a …


A Mathematical Study Of Two Retroviruses, Hiv And Htlv-I, Dana Ali Baxley Jan 2007

A Mathematical Study Of Two Retroviruses, Hiv And Htlv-I, Dana Ali Baxley

Electronic Theses and Dissertations

In this thesis, we examine epidemiological models of two different retroviruses, which infect the human body. The two viruses under study are HIV or the human immunodefiency virus and HTLV-I, which is the human T lymphotropic virus type I. A retrovirus is a virus, which injects its RNA into the host, rather than it's DNA. We will study each of the different mathematical models for each of the viruses separately. Then we use MATLAB-SIMULINK to analyze the models by studying the reproductive numbers in each case and the disease progression by examining the graphs. In Chapter 1, we mention basic …


Dynamics Of Cicrobial Communities Associated With Typha Angustifolia (Cattail) Litter In A Wetland Ecosystem: Effects Of Litter Manipulations On Microbial Decay Processes, Andrew John Foley Jan 2007

Dynamics Of Cicrobial Communities Associated With Typha Angustifolia (Cattail) Litter In A Wetland Ecosystem: Effects Of Litter Manipulations On Microbial Decay Processes, Andrew John Foley

Master's Theses and Doctoral Dissertations

Quantification of microbial processes involved in plant decomposition is important in understanding energy flow and nutrient recycling in wetlands. Prior studies examining emergent plant decomposition have often used litter that had been prematurely harvested (senescent) and/or manipulated (oven-dried). I examined the effects of litter manipulations on microbial decay dynamics associated with litter of the emergent macrophyte Typha angustifolia. Plant litter was harvested after senescence and after a period of standing-dead decay. This collected litter was either air-dried or oven-dried, placed into fine mesh (1 mm) litterbags, and submerged in the wetland. Litterbags were retrieved periodically and analyzed for microbial biomass, …

The Role Of Attention In Second Language Development, Amanda Marie Mcginnis Jan 2007

The Role Of Attention In Second Language Development, Amanda Marie Mcginnis

Graduate Student Theses, Dissertations, & Professional Papers

This pilot study investigated the role of attention in language learning. I began by examining the most current research into how attention functions in the brain; then I discussed how attention as a cognitive mechanism is believed to fit into models of data processing and language learning. Once the nature and role of attention in language development was understood, it became possible to discover the practical implications for language teachers and learners. The most recent means to a grammar pedagogy is the Focus on Form approach: a language teaching option which takes into account the research on the role of …


The Role Of The Macrophage In Asbestos Induced Autoantibody Production, David J. Blake Jan 2007

The Role Of The Macrophage In Asbestos Induced Autoantibody Production, David J. Blake

Graduate Student Theses, Dissertations, & Professional Papers

Environmental exposure to silicate compounds such as silica and asbestos has been associated with increased autoimmune responses and the development of autoimmune disease in humans. Residents of Libby, MT have experienced significant asbestos exposure due to an asbestos contaminated vermiculite mine near the community over several decades. Residents have developed numerous asbestos-related diseases as well as increased autoimmune responses. However, the exact mechanism by which Libby amphibole asbestos generates autoimmune responses is unclear. To elucidate a possible mechanism for asbestos induced autoimmunity, the cellular effects of Libby amphibole asbestos were characterized in vitro using a phagocytic murine macrophage cell line, …

Alternative Exon Usage Selectively Determines Both Tissue Distribution And Subcellular Localization Of The Acyl-Coa Thioesterase 7 Gene Products., Mary Hunt, Sinead Greene, Kjell Hultenby, L. Thomas Svensson, Susanna Engberg, Stefan E H Alexson

Articles

Acyl-CoA thioesterases (ACOTs) catalyze the hydrolysis of acyl-CoAs to free fatty acids and coenzyme A. Recent studies have demonstrated that one gene named Acot7, reported to be mainly expressed in brain and testis, is transcribed in several different isoforms by alternative usage of first exons. Strongly decreased levels of ACOT7 activity and protein in both mitochondria and cytosol was reported in patients diagnosed with fatty acid oxidation defects, linking ACOT7 function to regulation of fatty acid oxidation in other tissues. In this study, we have identified five possible first exons in mouse Acot7 (Acot7a-e) and show that all five first …

Characteristics Of Cooked Chickpeas And Soybeans During Combined Microwave–Convective Hot Air Drying, Aoife Gowen, Nissreen Abu-Ghannam, Jesus Maria Frias, Jorge Oliveira Jan 2007

Characteristics Of Cooked Chickpeas And Soybeans During Combined Microwave–Convective Hot Air Drying, Aoife Gowen, Nissreen Abu-Ghannam, Jesus Maria Frias, Jorge Oliveira

Articles

Moisture content, shrinkage, water activity (Aw), color and texture of cooked chickpeas and soybeans during convective, microwave and combined microwave–convective drying were studied. Combined drying was significantly (P < 0.05) faster than either convective or microwave drying, and resulted in less shrinkage of the dehydrated product. Rapid burning occurred when samples were dried below a Aw of 0.27 ± 0.07 for chickpeas (P < 0.05), and 0.13 ± 0.04 for soybeans (P < 0.05). Both chickpeas and soybeans displayed a transitional behavior in texture when dried to a Aw below 0.40 ± 0.10 (P < 0.05) for chickpeas, and below 0.63 ± 0.15 (P < 0.05) for soybeans, when samples became brittle. Shelf stable dehydrated chickpea and soybean products with low water activity (Aw = 0.35) and good visual quality could be obtained within 14 min of combination drying.


Effects Of Single Mutations On The Stability Of Horseradish Peroxidase To Hydrogen Peroxide., Barry Ryan, CiaráN Fagan Jan 2007

Effects Of Single Mutations On The Stability Of Horseradish Peroxidase To Hydrogen Peroxide., Barry Ryan, CiaráN Fagan

Articles

Horseradish Peroxidase (HRP) is a commonly used enzyme in many biotechnological fields. Improvement of HRP stability would further increase its potential application range. In the present study, thirteen single- and three double- mutants of solvent exposed, proximal lysine and glutamic acid residues were analysed for enhanced H2O2 stability. Additionally, five single- and one pentuple-consensus mutants were investigated. Most mutants displayed little or no alteration in H2O2 stability; however, three (K232N, K241F and T110V) exhibit significantly increased H2O2 tolerances of 25- (T110V), 18- (K232N), and 12- fold (K241F). This improved stability may be due to an altered enzyme-H2O2 catalysis pathway or …


Proteinparser:A Community Based Tool For The Generation Of A Detailed Protein Consensus And Fasta Output, Barry Ryan, Ronan Barrett Jan 2007

Proteinparser:A Community Based Tool For The Generation Of A Detailed Protein Consensus And Fasta Output, Barry Ryan, Ronan Barrett

Articles

Comparison of bioinformatic data is a common application in the life sciences and beyond. In this communication, a novel Java based software tool, ProteinParser, is outlined. This soft- ware tool calculates a detailed consensus, or most common, amino acid at a given position in an aligned protein set, whilst also generating a full consensus protein FASTA output. A second application of this software tool, computing a consensus amino acid given a toler- ance threshold, is also demonstrated. The phytase and the common bacterial �-lactamase proteins are analysed as ‘proof of concept’ examples. Consensus proteins, as generated by ProteinParser, are regularly …


"Big Love"'? The Recognition Of Customary Marriages In South Africa, Penelope Andrews Jan 2007

"Big Love"'? The Recognition Of Customary Marriages In South Africa, Penelope Andrews

Articles & Chapters

This Comment contextualizes the issue of polygamous marriages within the South African constitutional paradigm, one committed unequivocally to the principle of equality. This Comment analyzes how South African law, European in origin, had to incorporate the laws and institutions of indigenous communities within the national legal framework, as part of the overall transformative legal project underway in the country since 1994. By focusing on the Recognition of Customary Marriages Act, this Comment examines such incorporation, while questioning its effect on the overall project of constitutionalism, human rights, and equality.
