Argulus Yucatanus N. Sp. (Crustacea: Branchiura) Parasitic On Cichlasoma Urophthalmus From Yucatan, Mexico, William J. Poly

Gulf and Caribbean Research

A new species, Argulus yucatanus, is described based on 14 specimens from Cichlasoma urophthalmus collected in Celestun Lagoon, Yucatan, Mexico. Diagnostic characters include the number of and shape of sclerites in the suction cup support rods, shape of and position of respiratory areas, and modifications on the legs of males. In males, the coxae of the 2nd legs bear an angular lobe with 5–7 erect scales and 13–21 sensilla. The new species is compared to Argulus funduli Krøyer, 1863, A. chromidis Krøyer, 1863, A. cubensis Wilson, 1936, A. rhamdiae Wilson, 1936, and A. varians Bere, 1936.

Manatee Occurrence In The Northern Gulf Of Mexico, West Of Florida, D. Fertl, A.J. Schiro, G.T. Regan, C.A. Beck, N. Adimey, L. Price-May, A. Amos, G.A.J. Worthy, R. Crossland

Gulf and Caribbean Research

Reports of West Indian manatees (Trichechus manatus) in the US Gulf of Mexico west of Florida have increased during the last decade. We reviewed all available manatee sighting, capture, and carcass records (n = 377) from Alabama, Louisiana, Mississippi, and Texas since the early 1900s; only 40 of these were previously published. Manatees were reported most often in estuarine habitats, usually either near a freshwater source or natural or industrial warm-water springs/runoffs during winter months. The recent increase in manatee records may be due to a combination of increased public awareness and dispersal of manatees, most likely seasonal …

Selected Life-History Observations On The Cayman Gambusia, Gambusia Xanthosoma Greenfield, 1983 (Poeciliidae), Michael A. Abney, Richard W. Heard, Chet F. Rakocinski

Gulf and Caribbean Research

The Cayman gambusia (Gambusia xanthosoma Greenfield, 1983) is an uncommon species within the G. punctata species group, endemic to North Sound, Grand Cayman Island, BWI. Since the original description (Greenfield 1983) only phylogenetic information has been published and little is known of its habitat, feeding ecology, or reproductive life history (Wildrick and Greenfield 1985, Rauchenberger 1988). Originally described from a brackish-water (30 psu) mosquito control ditch, the species also occurred throughout marine mangrove habitat and inland saline ponds adjacent to North Sound, Grand Cayman Island. Here we present information on the habitat, diet, reproduction, life history, and parasites of …

Ecology Of The Mayan Cichlid, Cichlasoma Urophthalmus Günther, In The Alvarado Lagoonal System, Veracruz, Mexico, Rafael Chavez-Lopez, Mark S. Peterson, Nancy J. Brown-Peterson, Ana Adalia Morales-Gomez, Jonathan Franco-Lopez

Gulf and Caribbean Research

The Mayan cichlid, Cichlasoma urophthalmus, has a wide distribution in southeastern Mexico where it inhabits rivers and coastal lagoons. In the Alvarado lagoonal system, Veracruz, it is distributed towards the north in Camaronera Lagoon. The Mayan cichlid shows an affinity for oligohaline to mesohaline sites with submerged vegetation, well-oxygenated, deep, and transparent water. The major abundance and biomass of this species was obtained during December to February. The diet of Mayan cichlids consists principally of plant detrital material and algae. Length-frequency distribution shows 2 size classes during both the dry and rainy seasons, corresponding to reproductive fish and young …

Seasonal And Spatial Patterns In Salinity, Nutrients, And Chlorophyll Α In The Alvarado Lagoonal System, Veracruz, Mexico, Angel Moran-Silva, Luis Antonio Martinez Franco, Rafael Chavez-Lopez, Jonathan Franco-Lopez, Carlos M. Bedia-Sanchez, Francisco Contreras Espinosa, Francisco Gutierrez Mendieta, Nancy J. Brown-Peterson, Mark S. Peterson

Gulf and Caribbean Research

Ten monthly collections, distributed among three seasons, were taken from July 2000 to June 2001 in the Alvarado lagoonal system, Veracruz, Mexico. Variables measured in situ included dissolved oxygen, salinity, and water temperature. Water samples were collected to determine concentrations of ammonium, nitrates, nitrites, orthophosphates, total phosphorus and chlorophyll α. Collections representing the rainy season were taken in September and October, those for the nortes season were taken in November, December, and January, and dry season collections were taken during February, March, May June, and July. There was seasonal and spatial variation in nutrient concentrations, and they were related to …

Long-Term Fish Assemblage Dynamics Of The Alvarado Lagoon Estuary, Veracruz, Mexico, Rafael Chavez-Lopez, Jonathan Franco-Lopez, Angel Moran-Silva, Martin T. O'Connell

Gulf and Caribbean Research

The fish assemblages of Alvarado Lagoon Estuary (a complex of coastal lagoons in the state of Veracruz, Mexico) have been surveyed intermittently by different researchers over the last 40 years. Assessing longterm trends in fish assemblage composition for this ecosystem is problematic due to differences in sampling efforts among the survey periods (1966–1968, 1987–1988, 1989, 1989–1990, 1990–1991 and 2000–2001) and by the inherent ecological variability of estuaries. To overcome these data limitations and better understand fish assemblage change over time, we used robust, simulation-based analyses to compare collections from the different surveys. The 107 fish species collected from the Alvarado …

Political Psychology And Personality, Aubrey Immelman

Psychology Faculty Publications

Following a brief overview of historical approaches to personality-in-politics inquiry, this book chapter reviews the current state of the field – specifically, psychodynamic approaches, trait/motivational perspectives, and cognitive models – and argues that Theodore Millon’s personological model offers an integrative framework for assessing personality in politics and building a conceptual bridge between personality patterns and political leadership styles.

Millon’s model accounts for structural and functional personality attributes at the behavioral, phenomenological, intrapsychic, and biophysical levels of analysis and provides a theoretically coherent framework for studying personality in politics consonant with established principles in the adjacent sciences and integrative with respect …

Truly An Awesome Spectacle: Gender Performativity And The Alienation Effect In Angels In America, Allen Gorney

Electronic Theses and Dissertations

Tony Kushner's two-part play Angels in America uses stereotypical depictions of gay men to deconstruct traditional gender dichotomies. In this thesis, I argue that Kushner has created a continuum of gender performativity to deconstruct these traditional gender dichotomies, thereby empowering the effeminate and disempowering the masculine. I closely examine Kushner's use of Brechtian and Aristotelian tenets in the first Broadway production of the play to demonstrate that Kushner sought to induce social awareness of gay male oppression, contingent on the audience's perception of Kushner's deconstruction of the traditional gender dichotomy. I also scrutinize the role of the closet and its …

Only Screen Deep? Evaluating Aesthetics, Usability, And Satisfaction In Informational Websites, Carrie Avery

Electronic Theses and Dissertations

This thesis explores the role aesthetics plays in informational websites. In commercial interfaces, aesthetics (the perceived visual appeal and appropriateness of an object) has shown to correlate positively with many aspects of usability and emotional satisfaction. This thesis examines whether aesthetics has similar positive correlations in informational websites. Heuristics or guidelines for evaluating informational websites are developed based on empirical research and practitioner expertise. Categories for heuristic evaluation include usability, credibility, visual clarity, visual richness, and emotional satisfaction. A class of graduate students browsed three academic websites, evaluated them, and critiqued the heuristics. Results indicate that aesthetics does correlate with …

Measurement Of Lipid Peroxidation In Biology Models Using Gas-Chromatography-Aass Spectrometry, Madhavi Lokireddy

Master's Theses and Doctoral Dissertations

C2C12 mouse myoblast cells, grown in glass vials, were connected to a cryofocusing unit to trap volatile organic compounds (VOCs). The VOCs were eluted from the trap by capacitive discharge into a gas chromatograph with time-of-flight mass spectral capabilities (GC-TOFMS) and were found to include the lipid peroxidation product hexanal. The pro-oxidant cumene hydroperoxide elevated the levels of these lipid peroxidation products, whereas the anti-oxidant butylated hydroxy toluene (BHT) impaired their production. Derivatization of the aldehyde products of lipid peroxidation in the same myoblast cells with pentafluorobenzyl hydroxylamine hydrochloride (PFB) provided evidence for formation of non-volatile products of lipid peroxidation …
