A History Of Place: Using Phytolith Analysis To Discern Holocene Vegetation Change On Sanak Island, Western Gulf Of Alaska, Cricket C. Wilbur

Antioch University Dissertations & Theses

This study investigated a terrestrial climate proxy, phytoliths, as a complimentary approach to documenting the dynamics of present and past vegetation on Sanak Island, the largest island in a small island group in the eastern Aleutian archipelago, and as a new basis by which to interpret Holocene environmental variability in Alaska. A phytolith reference collection was established from 59 selected plant species of maritime tundra belonging to 27 families. The grass species and a sedge species produced abundant phytolith forms whereas the majority of dicotyledons in this study were trace producers of phytoliths. A paleoenvironmental reconstruction from fossil phytoliths recovered …

A Study Of The Spatial Dynamics Of Some Introduced Avian Species In The Southwest Region Of Western Australia, Desiree L. Moon

Theses: Doctorates and Masters

The Southwest region of Western Australia is a recognised ‘biodiversity hotspot’, as it possesses high levels of biodiversity and endemism; it also holds a number of species threatened by habitat loss. The arrival of Europeans in the region wrought major changes on the natural landscape. Extensive tracts of bushland were cleared for housing, infrastructure, forestry, farming, and mining. Another challenge to regional biodiversity was the spread of exotic plants and animals (including birds); the latter provide the focus for the present study. The research examines four bird species that colonised the Southwest region following European settlement: Australian White Ibis (Threskiornis …

The Fall Of "Augustinian Adam": Original Fragility And Supralapsarian Purpose, John Schneider

University Faculty Publications and Creative Works

This essay is framed by conflict between Christianity and Darwinian science over the history of the world and the nature of original human personhood. Evolutionary science narrates a long prehuman geological and biological history filled with vast amounts, kinds, and distributions of apparently random brutal and pointless suffering. It has also unveiled an original human person with animal psychosomatic heredity. This narrative seems to discredit Christianity's (Augustinian) metanarrative of the Fall-Paradise Lost and Paradise Regained. The author contends that the Augustinian story and its character of Adam are implausible, anyway, for reasons of theology and apologetics. He proposes that Christians …

Review Of Conspecific Attraction And Area Sensitivity Of Grassland Birds, David R.W. Bruinsma, Nicola Koper

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Many species of grassland birds are area sensitive, which may exacerbate the ecological effects of the extensive loss and fragmentation of grasslands that has taken place across the northern Great Plains. However, the reasons for this area sensitivity are unclear, as vegetation structure, matrix composition, and restriction of movements among patches do not seem to provide viable explanations for species native to grasslands. Con specific attraction, whereby species are behaviorally stimulated to select habitat or establish territories near individuals of the same species, may help explain this area sensitivity. We review and discuss theoretical and empirical research on avian conspecific …

The Ecological Role Of Rhizophytic Green Algae In Soft-Bottom Habitats, Laura Bedinger

USF Tampa Graduate Theses and Dissertations

Rhizophytic algae are large, abundant primary producers throughout tropical and subtropical areas worldwide where they grow as an understory in seagrass beds, as well as form mixed or monospecific beds of exclusively rhizophytic algal species. In this dissertation, "rhizophytic algae" refers to coenocytic green algae (Chlorophyta) in the order Bryopsidales that use a net of rhizoids to anchor in unconsolidated sediments. In the development of seagrass beds, rhizophytic algae colonize bare patches and are thought to facilitate seagrass colonization by stabilizing sediments and providing organic matter. However, despite their prominence little is known about many aspects of the ecology of …

Paleobiological Assessment Of Controls Underlying Long-Term Diversity Dynamics, Andrés L. Cárdenas

USF Tampa Graduate Theses and Dissertations

Deciphering the factors underlying both long-term patterns of diversity and taxonomic turnover rates (i.e., extinction, and origination) has been one of Paleobiology's major foci for the past three decades. The importance of documenting these components is that they will expand our ability to interpret and model the evolutionary processes underlying those trends, highlight the evolutionary impact of historical events, and contribute to the formulation of robust predictions about the future of global diversity in response to the current anthropologically driven environmental changes. Accordingly, the first part of this study examines the possible occurrence of global marine evolutionary environmental controls into …

From A Rodent To A Rhetorician: An Ideological Analysis Of George Alexander Kennedy's Comparative Rhetoric, James Begley

Masters Theses

George Alexander Kennedy, a professor of classics at the University of North Carolina at Chapel Hill, has given birth to a new understanding of rhetorical studies: he argues for the evolution of rhetoric from animals to humans. Using Sonja Foss's methodology of "ideological criticism," this thesis examined Kennedy's case as presented in his book, Comparative Rhetoric: an Historical and Cross-Cultural Introduction. This study discovered that the book was heavily influenced by a secular, pro-evolutionary ideology which dually contributed to its selective use of scientific evidences and production of inconsistent arguments. Evaluated on the basis of Biblical principles, this thesis concluded …

Channel Width And Least Tern And Piping Plover Nesting Incidence On The Lower Platte River, Nebraska, Joel G. Jorgensen, Mary Bomberger Brown, Andrew J. Tyre

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Endangered interior least terns (Sternula antillarum athalassos) and threatened northern Great Plains piping plovers (Charadrius melodus) nest together on midstream sandbars in large rivers in the interior of North America. We investigated the relationship between river channel width and tern and plover nesting incidence on the lower Platte River, Nebraska, using a model-based logistic regression analysis. Multiple channel width measurements and a long-term nesting data set were used in the analysis. Nesting incidence was positively associated with increasing river channel width proximal to the nesting site. At a greater distance, up to 802 m away from …

Reproduction And Population Characteristics Of White-Tailed Jackrabbits In South Dakota, Charles Dieter, Dustin Schaible

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

We evaluated the reproductive biology of314 white-tailed jackrabbits (Lepus townsendii) in 44 counties throughout South Dakota from June 2004 to September 2005. We classified jackrabbits as juveniles or adults based on the closure of the proximal epiphysis of the humerus using X-ray analysis. We determined annual reproductive activity through fluctuations in measured weights of reproductive organs for both sexes. The 2005 breeding season started in late February and proceeded until mid-July, approximately 142 days, allowing for females to potentially produce 3.3 litters. We found four distinct breeding periods by the overlap of estimated conception and parturition dates. Mean …

Plant Species Richness And Species Area Relationships In A Florida Sandhill, Monica Ruth Downer

USF Tampa Graduate Theses and Dissertations

Pine sandhill are integral pyrogenic communities in the southeastern United States. Though once widespread, habitat destruction, fire suppression and fragmentation have reduced the population to nearly 3%. It is important to learn as much as possible about these unique areas in order to implement best management practices to conserve and restore the existing populations of these communities.

Fire is central to the maintenance of pine sandhill communities and two conceptual hypothesis regarding burn frequency have come to light in maintaining the unique species composition and richness of these areas. The first is the Intermediate Disturbance Hypothesis which suggests that intermediate …

Assessing The Link Between Coastal Development And The Quality Of Fish Habitat In Mangrove Tidal Tributaries, Justin Micheal Krebs

USF Tampa Graduate Theses and Dissertations

To assess the potential influence of coastal development on the quality of estuarine habitat for nekton, we characterized land use and the intensity of land development surrounding small tidal tributaries of Tampa Bay. Based on this characterization, we classified tributaries as undeveloped, industrial, urban or man-made (i.e., mosquito-control ditches). Over one-third (37%) of tributaries were determined to be heavily developed, while fewer than one-third (28%) remain relatively undeveloped. We then examined the nekton community from eleven tributaries in watersheds representing the defined land-use classes. Whereas mean nekton density and species richness were both independent of land use, nekton-community structure differed …

The Kennebec River: A Historic Maine Resource, Elise Begin

Historical Ecology Atlas of New England

The Kennebec River has been considered one of Maine’s most important resources for at least the past 6-8 thousand years; its basin is located in west central Maine and drains 5,893 square miles, an area that is approximately one-fifth the area of the state. The river originates at Moosehead lake and runs 170 miles to the Atlantic Ocean. The river can be divided into two basins: the upper basin, which spans from Moosehead Lake to Waterville; and the lower basin, which spans from Waterville to the ocean.

Before the arrival of Europeans in 1606, the Abenaki Indians controlled the entirety …

Bath, Maine: A City Of Ships, Taylor Witkin

Historical Ecology Atlas of New England

Known as Maine’s city of ships, Bath sits on the shores of the Kennebec River, about 15 miles from the Gulf of Maine and 40 miles up the coast from Portland. Though small in population, Bath’s impact on Maine, the rest of United States, and even on the world has been anything but small. Today Bath is known mostly for the Bath Iron Works, which supplies the US Navy with a large portion of its fleets, however, in Bath’s early days it built large, wooden yachts and schooners mostly for trade, not war. The next few pages will explore Bath’s …

The Happy Valley, Cassie Raker

Historical Ecology Atlas of New England

On the Connecticut River in Western Massachusetts, there exists the Happy Valley. Surrounded by the humble Holyoke Range, today you will find a bustling New England settlement dominated by local colleges and universities. But it was not always so. The picturesque Mount Holyoke and its accompanying hotel, known as the Summit House, have overlooked the area for hundreds of years, watching it change from forest to farmland to industry to the modern landscape it is today.

Reintegrating Human And Nature: Modern Sentimental Ecology In Rachel Carson And Barbara Kingsolver, Richard M. Magee

English Faculty Publications

Rachel Carson and Barbara Kingsolver were both trained as scientists and may be expected to embrace the rationalist, mechanical view of nature as something separate from, and perhaps even inferior to, the world of humans. Yet these two women both promoted a more complex approach to modernism's scientific paradigm in which nature is not merely a separate entity for dispassionate study but also an integral part of the human community. Both women display in their rhetorical choices a keen understanding of the language of community and interconnection, and their language and writing styles constantly promote the reintegration of humans and …

Toward The History Of Study Of Symbiogenesis: On The English Translation Of B. M. Kozo-Polyansky’S A New Principle Of Biology (1924), Victor Fet

Victor Fet gives a brief history of this new translation, enthusiastically initiated and supported by Lynn Margulis (1938–2011), a famous naturalist who was always eager to gave credit …

Oyun: A New, Free Program For Iterated Prisoner’S Dilemma Tournaments In The Classroom, Charles H. Pence, Lara Buchak

Faculty Publications

Evolutionary applications of game theory present one of the most pedagogically accessible varieties of genuine, contemporary theoretical biology. We present here Oyun (oy-oon, http://charlespence.net/oyun), a program designed to run iterated prisoner's dilemma tournaments, competitions between prisoner's dilemma strategies developed by the students themselves. Using this software, students are able to readily design and tweak their own strategies, and to see how they fare both in round-robin tournaments and in “evolutionary” tournaments, where the scores in a given “generation” directly determine contribution to the population in the next generation. Oyun is freely available, runs on Windows, Mac, and Linux computers, …

Consequences Of Kleptoplasty On The Distribution, Ecology, And Behavior Of The Sacoglossan Sea Slug, Elysia Clarki, Michael Louis Middlebrooks

USF Tampa Graduate Theses and Dissertations

The sacoglossan sea slug Elysia clarki is able to photosynthesize for three to four months using chloroplasts sequestered from its algal food sources. Furthermore, the slug is able to store multiple chloroplasts from different algal species within the same cell. This research, consisting of several related studies, explores the role that provision of organic nutrients via photosynthesis plays in the biology of the slug. The first chapter demonstrates that, under conditions of starvation, photosynthetic activity in E. clarki remains fully functional for one month after which it then declines. During the first month of starvation the slug exhibits similar feeding …

Ontogeny And Littoral Structure Of Lakes Created On Phosphate Mined Lands Of Central Florida, Chrysoula Mitraki

USF Tampa Graduate Theses and Dissertations

Created lakes are an end product of phosphate mining in Florida. Beginning in 1975, Florida reclamation rules set criteria for phosphate created lakes aiming to approximate the structure of natural lakes, and emphasizing extensive littoral zones with both emergent and submersed vegetation.

Lake development relative to lake age and design were examined for 22 phosphate lakes representing a 40-year age trajectory, utilizing water quality and benthic invertebrate communities from littoral and deep-water locations (Chapter 1). The relative importance of morphometry and lake age in the development of littoral plant communities was examined using multiple vegetation surveys throughout the year, in …

Modification Of Trophic Links Between An Omnivore And Macroinfaunal Prey From Sandy Beaches Of Differing Physical Regimes, Kristina Joan Morrow

USF Tampa Graduate Theses and Dissertations

Sandy beach ecosystems have been studied worldwide; however, ecological data are sparse for the extensive barrier islands of Florida. Accordingly, I investigated the feeding patterns of the ghost crab (Ocypode quadrata), a dominant omnivore inhabiting beaches along the Floridian coast. Density data was collected for ghost crabs and swash macroinfaunal prey. In addition, I utilized stable isotopes in conjunction with the mixing models IsoSource and SIAR to characterize diets of ghost crabs across three barrier islands in spring and summer 2011. Results showed that ghost crabs at Cayo Costa feed primarily on swash macroinfauna, while those from Anclote Key shifted …

Use Of Adventitious Roots For The Determination Of Hydroperiod In Isolated Wetlands, Michael Joseph Reyes

USF Tampa Graduate Theses and Dissertations

Abstract

Accurate measurement of the hydroperiod in isolated wetlands currently relies upon the installation and frequent monitoring of devices such as piezometers and staff gauges. Observations of biological indicators of the hydroperiod may be able to supplement data collected from these devices and could potentially replace them as a means of accurately determining this hydrologic interval. The study objective was to determine whether adventitious root formation and maturation on buttonbush (Cephalanthus occidentalis) could be used as a viable indicator of the hydroperiod in isolated wetlands. Buttonbush seedlings were flooded in a controlled environment over a three month period in the …

Placing Birds On A Dynamic Evolutionary Map: Using Digital Tools To Update The Evolutionary Metaphor Of The "Tree Of Life", Sonia Stephens

Electronic Theses and Dissertations

This dissertation describes and presents a new type of interactive visualization for communicating about evolutionary biology, the dynamic evolutionary map. This web-based tool utilizes a novel map-based metaphor to visualize evolution, rather than the traditional "tree of life." The dissertation begins with an analysis of the conceptual affordances of the traditional tree of life as the dominant metaphor for evolution. Next, theories from digital media, visualization, and cognitive science research are synthesized to support the assertion that digital media tools can extend the types of visual metaphors we use in science communication in order to overcome conceptual limitations of traditional …

Stable Isotope Analysis Of Busycon Sinistrum To Determine Fort Walton-Period Seasonality At St. Joseph Bay, Northwest Florida, Ryan Michael Harke

USF Tampa Graduate Theses and Dissertations

ABSTRACT

Recent archaeological investigations indicate that coastal Fort Walton cultures in the St. Joseph Bay region of northwest Florida emphasized marine and estuarine foraging. These late prehistoric (A.D. 1000-1500) peoples collected fish, shellfish, and other aquatic resources. At the Richardson's Hammock site (8Gu10), radiocarbon-dated to about A.D. 1300, as at dozens of other shell middens around this salty bay, large gastropods were a major subsistence component. This adaptation is in sharp contrast with that of contemporaneous inland Fort Walton societies, who relied on maize agriculture. It is unknown whether coastal groups represent separate hunter-gatherer-fisher populations or seasonal migrations by inland …

Comparative Developmental Transcriptomics Of Echinoderms, Roy Vaughn

USF Tampa Graduate Theses and Dissertations

The gastrula stage represents the point in development at which the three primary germ layers diverge. At this point the gene regulatory networks that specify the germ layers are established and the genes that define the differentiated states of the tissues have begun to be activated. These networks have been well characterized in sea urchins, but not in other echinoderms. Embryos of the brittle star Ophiocoma wendtii share a number of developmental features with sea urchin embryos, including the ingression of mesenchyme cells that give rise to an embryonic skeleton. Notable differences are that no micromeres are formed during cleavage …

Swamp : Walking The Wetlands Of The Swan Coastal Plain ; And With The Exegesis, A Walk In The Anthropocene: Homesickness And The Walker-Writer, Anandashila Saraswati

Theses: Doctorates and Masters

This project is comprised of a creative work and accompanying exegesis. The creative work is a collection of poetry which examines the history and ecology of the wetlands and river systems of the Swan Coastal Plain, and which utilises the practice of walking as a research methodology. For the creative practitioner walking reintroduces the body as a fundamental definer of experience, placing the investigation centrally in the corporeal self, using the physical senses as investigative tools of enquiry. As Rebecca Solnit comments in her history of walking, ‘exploring the world is one of the best ways of exploring the mind, …
