Brevetoxin Body Burdens In Seabirds Of Southwest Florida, Karen E. Atwood

USF Tampa Graduate Theses and Dissertations

Harmful algal blooms (HABs, or "red tides") of the brevetoxin-producing dinoflagellate Karenia brevis occur periodically along Florida's Gulf coast. Mass mortalities of marine birds have long been associated with these blooms, yet there are few data documenting the accumulation of brevetoxins (PbTx) in the tissues of birds.

Post-mortem evaluations were performed on 185 birds representing 22 species collected from October 2001 through May 2006 during red tide and non-red tide events to quantify their body burdens of brevetoxins. A variety of tissues and organs were selected for brevetoxin analysis including blood, brain, heart, fat, stomach or gut contents, intestinal contents …

Predator Behavior And Prey Demography In Patchy Habitats, Brian J. Halstead

USF Tampa Graduate Theses and Dissertations

Habitat loss and fragmentation are among the greatest threats to biodiversity, and these threats can be exacerbated or alleviated by the presence of interacting species. The effect of habitat loss and fragmentation on predator-prey systems has received extensive theoretical attention, but empirical studies of these systems yield few clear patterns. I examined the influence of prey abundance and spatial distribution on the foraging ecology and spatial ecology of Masticophis flagellum (Coachwhip) using capture-mark-recapture and radio telemetry techniques. I also examined the influence of saurophagous snake abundance on the survival rate of Sceloporus woodi (Florida Scrub Lizard) populations. Masticophis flagellum positively …

Demography Of The Yarrow's Spiny Lizard, Sceloporus Jarrovii, From The Central Chihuahuan Desert, Héctor Gadsden, José L. Estrada-Rodríguez

Western North American Naturalist

The demography of a population of Yarrow's spiny lizard, Sceloporus jarrovii, was examined from 2004 to 2006 in the canyon Las Piedras Encimadas, located in Gomez Palacio, Durango, México. Lizards were studied using a mark-recapture technique. Reproduction in females occurred between November and May, coinciding with dry conditions. Reproductive activity was highest (percent of females with vitellogenic follicles or embryos) in the middle of the dry season (November and December). Thirteen percent of females reached sexual maturity at an average age of 8.5 months. The population structure was similar in spring and fall, but not in summer. A notable …

Geographic Patterns Of Ground-Dwelling Arthropods Across An Ecoregional Transition In The North American Southwest, David C. Lightfoot, Sandra L. Brantley, Craig D. Allen

Western North American Naturalist

We examined the biogeographic patterns of ground-dwelling arthropod communities across a heterogeneous semiarid region of the Southern Rio Grande Rift Valley of New Mexico. Our 3 sites included portions of 5 ecoregions, with the middle site a transition area where all ecoregions converged. We addressed the following 3 questions: (1) Do the species assemblage patterns for ground arthropods across habitats and sites conform to recognized ecoregions? (2) Are arthropod assemblages in distinct vegetation-defined habitats within an ecoregion more similar to each other or to assemblages in similar vegetation-defined habitats in other ecoregions? (3) Is there a detectable edge effect with …

Fashion Advertising, Men’S Magazines, And Sex In Advertising: A Critical-Interpretive Study, Jennifer Ford

USF Tampa Graduate Theses and Dissertations

This study examines sexualized portrayals of women in fashion advertising found in metro-sexual men's magazines as visual rhetoric. Historically, studies on sexual images of women in advertising have focused on content analyses of these images and how they affect women. This study asks how sexualized imagery of women functions rhetorically as part of a branding message designed to sell products. The exemplar advertisements were chosen specifically for their sexual imagery from an earlier study by the researcher on sexual images of women in fashion advertisements found in men's magazines.

The messages interpreted within the visuals of this study reveal a …

The Case For Humboldtensis: A Subspecies Name For The Indigenous Cutthroat Trout (Oncorhynchus Clarkii) Of The Humboldt River, Upper Quinn River, And Coyote Basin Drainages, Nevada And Oregon, Patrick C. Trotter, Robert J. Behnke

Western North American Naturalist

In the early years of his research on the native trouts of western North America, Behnke (1960, 1966, 1979) observed consistent differences in certain meristic characters between the cutthroat trout of the Humboldt River drainage and those from the Truckee, Carson, and Walker river drainages of the Lahontan Basin, and proposed that the Humboldt trout be recognized as a distinct subspecies. He coined the subspecies name humboldtensis, but a formal description was never published. Here we again present the early evidence for subspecific distinction of the Humboldt drainage cutthroat trout, and add more recent findings from the fields of …

Dynamics Of Rodent Populations In Semiarid Habitats In Lassen County, California, Sara C. Gillespie, Dirk H. Van Vuren, Douglas A. Kelt, John M. Eadie, Daniel W. Anderson

Western North American Naturalist

From 1996 to 2004, we studied population dynamics of a rodent assemblage in semiarid habitats in Lassen County, California. Abundances of rodents appeared affected by fluctuations in precipitation from a high in 1996 to average and slightly below-average levels in subsequent years; perhaps reflecting this, assemblage composition also changed dramatically during the study period. California kangaroo rats (Dipodomys californicus) declined from abundant to extremely rare, abundances of deer mice (Peromyscus maniculatus) fluctuated greatly during the study period, and, perhaps most notably, populations of dusky-footed woodrats (Neotoma fuscipes) appeared to decline to local extinction, possibly …

Observations On Body Mass Of Prairie Dogs In Urban Habitat, Seth B. Magle

Western North American Naturalist

The black-tailed prairie dog is an important component of prairie and steppe ecosystems. Currently many prairie dog colonies are fragmented by, or adjacent to, urban development, but little is known about what effects urbanization may have on these animals. I compare body weights and sex ratios of prairie dogs in isolated urban habitat in Denver, Colorado, to published data for black-tailed prairie dogs at the same time of year. Prairie dogs in this study had summer weights similar to those reported in the literature, although males apparently gained weight earlier in the year, and observed sex ratios were not significantly …

Recognition Memory For Emotional Words: An Event Related Potential Study, Catherine C. Balderston

USF Tampa Graduate Theses and Dissertations

Evidence suggests that emotion affects memory often yielding enhanced recall and recognition of stimuli with emotional content. The nature of the relationship between emotion and memory for words has been particularly difficult to parse in part because of the stimulus characteristics. For example, emotional words tend to engender greater levels of physiological and psychological arousal, which have also been shown to enhance memory. Inter item relatedness has also been suggested as playing a part in the observed effects (i.e., emotional words belong to a closed semantic category compared to neutral words and are therefore easier to remember). While the enhancement …

The Drowned Girl, Karen Brown Gonzalez

USF Tampa Graduate Theses and Dissertations

The Drowned Girl is a novel-in-stories that depicts the lives of eight characters living in a small Connecticut town. This work is one told through varying perspectives. Characters are mothers and fathers, husbands and wives, daughters, sons, and lovers. Their lives intersect physically, and emotionally, and the separate stories reveal the facets and repercussions of events both past and present: the death of a son and brother in a car accident, the life and death of a notorious town figure, the past and tragic future of a young woman, Jules, whose body is found one spring in the Connecticut river. …

Tightly Integrating Optical And Inertial Sensors For Navigation Using The Ukf, Sedat Ebcin

Theses and Dissertations

The motivation of this research is to address the benefits of tightly integrating optical and inertial sensors where GNSS signals are not available. The research begins with describing the navigation problem. Then, error and measurement models are presented. Given a set of features, a feature detection and projection algorithm is developed which utilizes inertial measurements to predict vectors in the feature space between images. The unscented Kalman filter is applied to the navigation system using the inertial measurements and feature matches to estimate the navigation trajectory. Finally, the image-aided navigation algorithm is tested using a simulation and an experiment. As …

Rnai-Mediated Gene Silencing In Tick Synganglia: A Proof Of Concept Study, Shahid Karim, Bronwyn Kenny, Emily Troiano, Thomas N. Mather

Plant Sciences and Entomology Faculty Publications

Background: Progress in generating comprehensive EST libraries and genome sequencing is setting the stage for reverse genetic approaches to gene function studies in the blacklegged tick (Ixodes scapularis). However, proving that RNAi can work in nervous tissue has been problematic. Developing an ability to manipulate gene expression in the tick synganglia likely would accelerate understanding of tick neurobiology. Here, we assess gene silencing by RNA interference in the adult female black-legged tick synganglia.

Results: Tick β-Actin and Na⁺-K⁺-ATPase were chosen as targets because both genes express in all tick tissues including synganglia. …
