Tissue-Diet Discrimination Factors And Turnover Of Stable Carbon And Nitrogen Isotopes In White-Footed Mice (Peromyscus Leucopus), Rachel L. Demots, James M. Novak, Karen F. Gaines, Aaron J. Gregor, Christopher S. Romanek, Daniel A. Soluk
Tissue-Diet Discrimination Factors And Turnover Of Stable Carbon And Nitrogen Isotopes In White-Footed Mice (Peromyscus Leucopus), Rachel L. Demots, James M. Novak, Karen F. Gaines, Aaron J. Gregor, Christopher S. Romanek, Daniel A. Soluk
Faculty Research & Creative Activity
Stable isotope analysis has become an increasingly valuable tool in investigating animal ecology. Here we document the turnover rates for carbon in the liver, muscle, and whole blood tissue, as well as the tissue-diet discrimination values for carbon and nitrogen isotopes in the liver, whole blood, muscle, and hair, of the white-footed mouse (Peromyscus leucopus (Rafinesque, 1818)). A 168-day diet-switching experiment was conducted with a laboratory population of white-footed mice. The δ13C values for all tissues deviated less than 1‰ from those of the diet except for whole blood, which had a slightly higher tissue-diet discrimination factor of 1.8‰. All …
Mechanisms Of Apoptosis In Crustacea: What Conditions Induce Versus Suppress Cell Death?, Michael A. Menze, Grady Fortner, Suman Nag, Steven C. Hand
Mechanisms Of Apoptosis In Crustacea: What Conditions Induce Versus Suppress Cell Death?, Michael A. Menze, Grady Fortner, Suman Nag, Steven C. Hand
Faculty Research & Creative Activity
Arthropoda is the largest of all animal phyla and includes about 90% of extant species. Our knowledge about regulation of apoptosis in this phylum is largely based on findings for the fruit fly Drosophila melanogaster. Recent work with crustaceans shows that apoptotic proteins, and presumably mechanisms of cell death regulation, are more diverse in arthropods than appreciated based solely on the excellent work with fruit flies. Crustacean homologs exist for many major proteins in the apoptotic networks of mammals and D. melanogaster, but integration of these proteins into the physiology and pathophysiology of crustaceans is far from complete. Whether apoptosis …
Slope-Driven Goal Location Behavior In Pigeons, Daniele Nardi, Kristian P. Nitsch, Verner P. Bingman
Slope-Driven Goal Location Behavior In Pigeons, Daniele Nardi, Kristian P. Nitsch, Verner P. Bingman
Faculty Research and Creative Activity
A basic tenet of principles of associative learning applicable to models of spatial learning is that a cue should be assigned greater weight if it is a better predictor of the goal location. Pigeons were trained to locate a goal in an acute corner of an isosceles trapezoid arena, presented on a slanted floor with 3 (Experiment 1) or 2 (Experiment 2) orientations. The goal could be consistently determined by the geometric shape of the arena; however, its position with respect to the slope gradient varied, such that slope position was not a good predictor of the goal. Pigeons learned …
Responses Of Bats To Forest Fragmentation In The Mississippi River Alluvial Valley, Arkansas, Usa, Rex E. Medlin Jr., Matthew B. Connior, Karen F. Gaines, Thomas S. Risch
Responses Of Bats To Forest Fragmentation In The Mississippi River Alluvial Valley, Arkansas, Usa, Rex E. Medlin Jr., Matthew B. Connior, Karen F. Gaines, Thomas S. Risch
Faculty Research & Creative Activity
Intense conversion of bottomland hardwood forests to rice and soybeans in the Mississippi River Valley of Arkansas has restricted the remaining forest to isolated fragments. Habitat fragmentation has proven to be detrimental to population sustainability of several species, and is the subject of intense study with often species and latitude specific responses. We compared both coarse land area classes and landscape fragmentation metrics from six 30 km × 30 km subsets centered on publicly owned management areas to bat captures obtained from a 2005 population study. Patch density was the strongest predictor of total captures (R 2 = 0.801, p …

Reconstitution Of The Olfactory Epithelium Following Injury In Apoe-Deficient Mice, Britto P. Nathan, Salina Gairhe, Ikemefuna Nwosu, Stephen Clark, Robert G. Struble
Faculty Research & Creative Activity
ApoE, a protein component of lipoproteins, is extensively expressed in the primary olfactory pathway. Because apoE has been shown to play a vital role in nerve repair and remodeling, we hypothesized that apoE expression will increase in the injured olfactory epithelium (OE), and that apoE deficiency in apoE knockout (KO) mice will lead to delayed/incomplete reconstitution of the OE following injury. To directly test this hypothesis, we compared OE regeneration in wild-type (WT) and KO mice following injury induced by intranasal irrigation of Triton X-100. OE was collected at 0, 3, 7, 21, 42, and 56 days post lesion. The …

Faculty Research & Creative Activity
Stylisma pickeringii var. pattersonii (Convolvulaceae) is endangered in Illinois and Iowa, and occurs in scattered populations in other states. During 1999 and 2000, two insect species previously unreported from Illinois were observed visiting its flowers. This study was undertaken to survey additional insect visitors, as well as to characterize the plant community where S. pickeringii occurs. The objectives were to survey: 1) floral traits (anthesis and flower density) of S. pickeringii, 2) associated plant species, and 3) insect visitor characteristics. Floral traits were determined and associated plant species surveyed in Mason County (degraded hay field on private property) and Henderson …
The Role Of Slope In Human Reorientation, Daniele Nardi, Nora S. Newcombe, Thomas F. Shipley
The Role Of Slope In Human Reorientation, Daniele Nardi, Nora S. Newcombe, Thomas F. Shipley
Faculty Research and Creative Activity
Studies of spatial representation generally focus on flat environments and visual stimuli. However, the world is not flat, and slopes are part of many natural environments. In a series of four experiments, we examined whether humans can use a slope as a source of allocentric, directional information for reorientation. A target was hidden in a corner of a square, featureless enclosure tilted at a 5° angle. Finding it required using the vestibular, kinesthetic and vis-ual cues associated with the slope gradient. Participants succeeded in the task; however, a large sex difference emerged. Men showed a greater ability in using slope …
Spatiotemporal Dynamics Of Lianas During 50 Years Of Succession To Temperate Forest, Laura Ladwig, Scott J. Meiners
Spatiotemporal Dynamics Of Lianas During 50 Years Of Succession To Temperate Forest, Laura Ladwig, Scott J. Meiners
Faculty Research & Creative Activity
Although they are important components of forest communities, the general ecology and spatiotemporal patterns of temperate lianas during forest regeneration are largely unknown. The dependence of lianas on other plants for physical support makes them a potentially important driver of community dynamics. We examined 50 years of vegetation data from an old-field succession study to determine the dynamics and community controls on liana expansion within the Piedmont region of New Jersey, USA. Four lianas, Lonicera japonica, Parthenocissus quinquefolia, Toxicodendron radicans, and Vitis spp., occurred in enough abundance for detailed analyses. In general, liana cover peaked during mid-succession (20–30 years post-abandonment) …

Dna Double-Strand Breakage As An Endpoint To Examine Metal And Radionuclide Exposure Effects To Water Snakes On A Nuclear Industrial Site, Stephanie M. Murray, Karen F. Gaines, James M. Novak, Michael Gochfeld, Joanna Burger
Faculty Research & Creative Activity
This study examined metal levels (especially U and Ni) in the tail tissues of water snakes from contaminated (Tim’s Branch) and reference areas on the Department of Energy’s Savannah River Site (SRS). Home ranges of snakes were quantified to determine the ratio of the habitat that they use in relation to the contaminated areas to better estimate exposure Compared to conventional methods that do not. The exposure assessment indicated that water snakes in the contaminated areas could expect U exposure at 3–4 orders of magnitude greater than the Agency for Toxic Substances and Disease Registry’sMinimum Risk Level (MRL) from ingestion …

Physiological Status Of Male And Female Popillia Japonica (Coleoptera: Scarabaeidae) Affects Mating And Grouping Behavior, Natasha Tigreros, Rashmi Jadhav, Katelyn A. Kowles, Britto P. Nathan, Paul Switzer
Faculty Research & Creative Activity
Because mating may be costly, sexually active males or females are predicted to be in relatively good physiological condition and may preferentially direct their mating behavior toward relatively high-quality mates. We tested this hypothesis in Japanese beetles (Popillia japonica Newman), a pest species in which males and females may be either isolated or in aggregations while feeding on host plants. We examined male size and lipid content and female size and egg load with respect to both their pairing status and whether they were isolated or in aggregations. Males that were paired had the highest lipid levels, and single, isolated …

An Economic Model Of Literary Studies, Devin Charles Black
An Economic Model Of Literary Studies, Devin Charles Black
Masters Theses
While much scholarly discussion exists on the future of literary studies and its value to society at large, much of this discussion revolves around economic terminology, such as value, without discussing the issues and concerns of literary studies in a larger economic framework. In this project, I look at the advent ofliterary theory as the catalyst that transformed literary studies into a capitalist economic system. This project aims to look at the complexity of value systems operating within the discipline without championing one theory over another or, indeed, championing or arguing against theory itself. Instead, an economic model allows us …
Monstrous Transformations: Loyalty And Community In Four Medieval Poems, Mary Lieske
Monstrous Transformations: Loyalty And Community In Four Medieval Poems, Mary Lieske
Masters Theses
The thesis focuses on loyalty as performed by individuals within a social community and on how loyalty is a necessity for knights. The four poems I examined, Bisclavret, Guillaume of Palerne, The Wife of Bath's Tale and Sir Gawain and the Green Knight, include a transformation that enhances the acts of loyalty either by forcing characters and readers to focus on the acts themselves or by complicating the acts with the addition of social expectations and additional promises. The thesis is separated into two chapters categorized by transformation type. The human-to-animal transformation focuses on the acts ofloyalty and their ties …
Wordsworth, Emerson, And The "Art Of Loss", Nicholas M. Shaner
Wordsworth, Emerson, And The "Art Of Loss", Nicholas M. Shaner
Masters Theses
The discussion in Robert Weisbuch's Atlantic Double-Cross about the ways in which American writers wrote both with and against their British contemporaries is analogous to the way Ralph Waldo Emerson is influenced by and connected to William Wordsworth through the "art of loss". Wordsworth is the poet of human suffering, and through many of his poems about dealing with loss and mortality, especially, The Excursion, and the "Intimations Ode," he has a profound impact on Emerson. Emerson's ability to deal with the loss of his young son Waldo is difficult, and he attempts to look to Wordsworth's poems on death …

Multiple Endpoints Of Endocrine Disruption In Gravid Watersnakes (Colubridae:Nerodia) As A Function Of Ingestion Of A Common Herbicide, Lorin Anne Neuman-Lee
Multiple Endpoints Of Endocrine Disruption In Gravid Watersnakes (Colubridae:Nerodia) As A Function Of Ingestion Of A Common Herbicide, Lorin Anne Neuman-Lee
Masters Theses
Ecotoxicological studies that focus on a single endpoint might not accurately represent the true ecological effects of a contaminant. Exposure to atrazine, a widelyused herbicide, disrupts endocrine function and sexual development in amphibians, but studies involving reptilian species are lacking. This study examines several effects of atrazine ingestion on gravid females and neonates exposed in utero of the Northern Watersnake (Nerodia sipedon). Twenty-five gravid N. sipedon were collected and kept in the lab for the entirety of their gestation period. Each snake received one of four doses of atrazine: control, 2, 20, or 200 ppb. Blood samples were drawn each …
A Spatially Explicit Model To Predict Radiocesium Body Burdens In White-Tailed Deer On The Department Of Energy's Savannah River Site, Christopher W. Bobryk
A Spatially Explicit Model To Predict Radiocesium Body Burdens In White-Tailed Deer On The Department Of Energy's Savannah River Site, Christopher W. Bobryk
Masters Theses
A spatially explicit exposure model was developed to interpolate and predict radiocesium (137Cs) body burdens found in white-tailed deer (Odocoileus virginianus) on the U.S. Department of Energy's Savannah River Site (SRS) in west-central South Carolina. Since 1965 hunting has been allowed from permanent stands as a mechanism to manage the herd and all animals have been monitored in the field for gross beta/gamma activity levels providing a long-term spatially explicit dataset. Until now no study has attempted to model deer 137Cs at the hunt-stand level, but rather at the compartment level (1,000 - 5,200 ha). The models described here use …
Prey Preference As A Function Of Feeding Experience And Prey Type In Neonate Gartersnakes (Colubridae: Thamnophis), Kathryn B. Hale
Prey Preference As A Function Of Feeding Experience And Prey Type In Neonate Gartersnakes (Colubridae: Thamnophis), Kathryn B. Hale
Masters Theses
Several species of potential prey have been introduced into the geographic range of the Two-striped Gartersnake, Thamnophis hammondii. Some of these prey species possess defenses that present novel challenges to the snake predator. Despite novel predator defense mechanisms (including secretions from skin glands), adult T. hammondii ingest several of these prey species without adverse effects. Although ~dult T hammondii are dietary generalists, almost nothing is known about prey preferences in newborn individuals that lack feeding experience. My study determined whether or not T. hammondii innately exhibits a preference among native and introduced prey types. Furthermore, I compared the degree of …

The Best Predictors Of Self-Reported Depressed Mood In Adolescents, Melissa H. Wineberg
Masters Theses
The present study examined multiple predictors of depression simultaneously in order to determine which variables best predict self-reported depressed mood in adolescents. Although the current literature has identified several individual variables and their relationship to depression in adolescents, few studies have investigated multiple variables at the same time in relation to depression. Participants included 4,693 high school students from a Midwestern state. Of these students, 4 7% were girls, 4 7% were boys, and 6% did not indicate their gender. These students attended various high schools across seven counties and were recruited for a health prevention program called I Sing …
Increasing Written Language Skills Utilizing Writing Software And Traditional Methods, Caroline Larson
Increasing Written Language Skills Utilizing Writing Software And Traditional Methods, Caroline Larson
Undergraduate Honors Theses
A grid based computer program, Clicker5, appeared to have many features that logically may assist struggling writers. It utilizes pictures, sound, speech synthesis, word banks and a spelling checker. Karemaker et al. (2008) examined the use of Clicker5 and observed increased attention and focus during reading, and greater gains in word recognition and rhyme awareness. Scattered research exists on some of the multimedia features that Clicker5 utilizes (e.g. auditory and visual instruction, specific feedback, student specific examples, Wissick & Gardner, 2000; composition processes and revision facilitation, MacArthur 2000; spell checkers with strategy instruction, and speech synthesis to increase error …
