Raccoons As Potential Vectors Of Radionuclide Contamination To Human Food Chains From A Nuclear Industrial Site, Karen F. Gaines, Christine G. Lord, C. Shane Boring, I. Lehr Brisbin Jr., Michael Gochfeld, Joanna Burger

Faculty Research & Creative Activity

Although the raccoon (Procyon lotor) is commonly harvested and consumed throughout the southeastern United States, little is known regarding the fate and effects of environmental pollutants to this species, and the potential for it to act as a contaminant vector to humans or other predators. Muscle and liver tissues were collected from 76 raccoons from locations on and near the Department of Energy's Savannah River Site (SRS) in South Carolina and analyzed for radiocesium (137Cs). Raccoons were trapped from areas near a former reactor cooling reservoir known to be contaminated from former nuclear production activities, a stream drainage system also …

Season And Distance From Forest - Old Field Edge Affect Seed Predation By White-Footed Mice, Scott J. Meiners, James T. Mccormick

Faculty Research & Creative Activity

We studied the spatial pattern of seed predation across a forest-old field edge in both fall and winter to assess the potential for seed predators to influence plant spatial patterns. We used a 100 x 100 m grid that began 30 m inside the forest and extended 60 m into the old field. Inside this grid we placed seed stations at regular 10 m intervals and monitored seed removal. Seed predation varied significantly across the edge gradient in both fall and winter with the highest rate of seed removal at the edge in both trials. The spatial pattern of seed …

Metals And Metallothionein In The Liver Of Raccoons: Utility For Environmental Assessment And Monitoring, Joanna Burger, Christine G. Lord, Edward J. Yurkow, Lynn Mcgrath, Karen F. Gaines, I. Lehr Brisbin Jr., Michael Gochfeld

Faculty Research & Creative Activity

The relationship between metallothionein levels and concentrations of several metals and radionuclides was examined in liver tissues of raccoons (Procyon lotor, n = 47) from the Department of Energy’s Savannah River Site in South Carolina to determine the applicability of metallothioneins as an initial screening device for exposure assessment in free-living mammals and environmental monitoring. Using a fluorescent marker and a cell sorter to measure metallothionein, a significant positive correlation was found across animals between levels of metallothioneins and concentrations of selenium (Pearson’s r = .30) , mercury (Pearson’s r = .31) , and copper (Pearson’s r = .30) in …

Proximate Constraints On Intruder Detection In The Dragonfly Perithemis Tenera (Odonata: Libellulidae): Effects Of Angle Of Approach And Background, Paul V. Switzer, Perri K. Eason

Faculty Research & Creative Activity

The implications of insects’ vision for territorial defense have been relatively little studied in the field. In the dragonfly Perithemis tenera Say we investigated whether either the angle at which an intruder was viewed by a territorial resident or the background against which it was viewed affected the detection of that intruder. Residents detected intruders at a greater distance if the intruders were directly in front of them; they also detected more intruders in front of them than from other angles. Intruders viewed against distant vegetation were detected more readily than were intruders against near vegetation. Residents detected more intruders …

Predation Rates On Real And Artificial Nests Of Grassland Birds, William B. Davison, Eric K. Bollinger

Faculty Research & Creative Activity

We estimated nesting success at real and artificial nests of grassland birds to test the influence of nest type, nest position, and egg size on predation rates. We distributed wicker nests and realistic woven-grass nests baited with a clay egg and either a Northern Bobwhite (Colinus virginianus) egg or a House Sparrow (Passer domesticus) egg in four grasslands that were part of the Conservation Reserve Program in east-central Illinois. Nesting success averaged 86.5% for 12 days of exposure for artificial nests. For real nests, nesting success was markedly lower, averaging 39% over the entire nesting cycle and 59% during approximately …

Binding Of Urate And Caffeine To Hemocyanin Of The Lobster Homarus Vulgaris (E.) As Studied By Isothermal Titration Calorimetry †, Michael A. Menze, Nadja Hellmann, Heinz Decker, Manfred K. Grieshaber

Faculty Research & Creative Activity

Hemocyanin serves as an oxygen carrier in the hemolymph of the European lobster Homarus Vulgaris. The oxygen binding behavior of the pigment is modulated by metabolic effectors such as lactate and urate. Urate and caffeine binding to 12-meric hemocyanin (H. Vulgaris) was studied using isothermal titration calorimetry (ITC). Binding isotherms were determined for fully oxygenated hemocyanin between pH 7.55 and 8.15. No pH dependence of the binding parameters could be found for either effector. Since the magnitude of the Bohr effect depends on the urate concentration, the absence of any pH dependence of urate and caffeine binding to oxygenated hemocyanin …

Foraging Ecology Of The Endangered Wood Stork Recorded In The Stable Isotope Signature Of Feathers, Christopher S. Romanek, Karen F. Gaines, A. L. Bryan Jr., I. L. Brisbin Jr.

Faculty Research & Creative Activity

Down feathers and regurgitant were collected from nestling wood storks (Mycteria americana) from two inland and two coastal breeding colonies in Georgia. The stable isotopic ratios of carbon ( 13 C/12 C) and nitrogen ( 15N/ 14N) in these materials were analyzed to gain insights into the natal origins of juvenile storks and the foraging activities of adults. Down feathers differed in δ 13 C between inland and coastal colonies, having average isotopic values that reflected the sources of carbon fixed in biomass at the base of the food web. Feathers from the inland colonies differed between colonies in δ …

Rural African Americans And Progressive Reform, Debra A. Reid

Faculty Research & Creative Activity

Histories of African Americans in the postbellum rural South tend to depict sharecroppers and tenants as victims of the crop lien system, racism, and the capitalization of agriculture. This paper concentrates instead on rural re? formers who celebrated life in the country and believed that comfortable homes, better schools, and wholesome residents could free blacks from bondage. Their agrarian ideology reflected Euro-American influences; most believed in the Jeffersonian rhetoric that linked land ownership to virtue and independence. Because they realized that the crop lien system made prop? erty acquisition an impossible dream for most blacks, they advocated diversification and sustainable …

The Effect Of Predator Chemical Cues And Conspecific Alarm Signals Upon Behavior In Early And Late Developmental Stages Of American Toad (Bufo Americanus) Tadpoles, Carol Lynette Johnson

Masters Theses

The chemosensory capability and subsequent habitat choice of larval American toad (Bufo americanus) tadpoles were quantified using choice of refuge with both early and late developmental stages. Treatments were performed with two tadpole densities to ascertain the effect of social aggregations upon behavior. Bluegill (Lepomis macrochirus) and predaceous diving beetle larvae (Dytiscus sp.) predators were used to condition water. Conspecific tadpoles as well as Southern leopard frog (Rana sphenocephala) tadpoles were used to prepare treatment extracts.

Tadpole density (n=10 and n=20) had no significant effect upon the percentage of tadpoles seeking cover …

Effects Of Apolipoprotein E On Neurite Outgrowth From Adult Mice Cortical Neurons, Yanwen Jiang

Masters Theses

Apolipoprotein (apo) E4, one of the three common isoforms of apoE, has been implicated in Alzheimer's disease (AD). The mechanism whereby apoE4 leads to the pathogenesis of AD is unknown. In the present study, I examined the effects of apoE on neurite outgrowth from adult mice cortical neurons (AMC) in culture. I found that neurite outgrowth from AMC neurons derived from apoE deficient/apoE gene knockout (apoE KO) mice is significantly shorter than that from age-, sex-, and strain-matched wild-type control mice. Furthermore, I present evidence for the differential effects of two isoforms of human apoE, apoE3 and apoE4, on neurite …

The study lasted five weeks with one week of pre-testing, three weeks of creatine use which included one week of loading (12-13 g/day for seven days) and two weeks of maintenance (3-4 g/day for 14 days), and one week of post testing. Pre- and post-test strength were measured with a one repetition maximal lift (1RM) on the bench press and the leg press. All subjects …

Patterns And Implications Of Aberrant Singing Behaviors Of Black-Capped (Poecile Atricapillus) And Carolina (Poecile Carolinensis) Chickadees In Illinois, Patrick Caesar Enstrom

Masters Theses

I studied the singing behavior of the closely related Black-capped (Poecile atricapillus) and Carolina (Poecile carolinensis) Chickadees along their range interface in central Illinois. These sibling species are parapatrically distributed from the Appalachians through the Midwest to Kansas. Where their ranges do overlap, small hybrid zones form and chickadees in these areas frequently sing aberrant songs. The majority of the songs studied were recorded 17 April-16 July 1999 in fifteen counties throughout central Illinois. I measured 8 frequency and duration characteristics of the first two notes of songs that began with two whistled notes. The averages of these characteristics …

Lessing And Emerson: Conscious Evolution And Ideal Reality, Rachel Hills Newell

Masters Theses

Although Doris Lessing writes during the twentieth century in England and Ralph Waldo Emerson wrote during the nineteenth century in America, they both explore the complexity of human existence through their work. Both authors visualize the possibility of an "ideal reality," or human evolution, and believe human beings are capable of transforming ordinary, or actual, reality into ideal reality. The human potential for the creation of the ideal, however, depends on the development of that potential to its fullest extent. Lessing and Emerson believe only the individual is capable of completely developing human potential. Through a series of steps, or …

Audre Lorde's Expansive Influence On Black Lesbians: Jewelle Gomez, Cheryl Clarke, And Kate Rushin, Denise L. Fitzer

Masters Theses

Audre Lorde, who named herself black, feminist, lesbian, mother, poet, and activist, was a pioneer for black lesbians everywhere. In her poetry and prose, Lorde challenged the myths and taboos associated with black women, lesbians, and feminists. Although her work focused on a broad range of topics that illuminated her many identities, she concentrated most heavily on issues of multiple oppression and its resulting fear and silence. In naming herself, Lorde urged others to do the same — to fight the self-imposed and socially-imposed silence surrounding triple oppression.

Countless women from the black community of writers have paid tribute to …

From Hierarchy To Balance: Anne Bradstreet's Union Of Renaissance And Puritan Influences, Christy Shannon

Masters Theses

Anne Bradstreet was confronted with two very different influences when she began writing her poetry. One was the Renaissance literary style that she encountered in her native England; the other was a strict Puritan upbringing that would be the controlling factor of her life in the colonies. Both of these influences put a strong emphasis on order and a hierarchical structure. Bradstreet was unable to accept either of these influences completely, but she did manage to combine them in order to create some of the most interesting and memorable poetry of her time. The conflict that she faces is evident …

Effect Of Antioxidants On Ultra High Molecular Weight Polyethylene (Uhmwpe), Clifford Schrader

Masters Theses

This thesis presents a study on the effects of antioxidants on the oxidative induction time (OIT), thermal behavior, and hardness property of ultra high molecular weight polyethylene (UHMWPE). The antioxidants were dissolved into methanol alcohol before the solution was mixed with UHMWPE powder. The mixture was degassed under vacuum, and then compression-molded into disks 1.25 in. in diameter.

Different antioxidants were evaluated at concentrations up to 0.6 percent. A 0.6 percent concentration was used to screen the effectiveness of various antioxidants. Effect of antioxidant concentration was investigated in the range between 0 and 0.6 percent. OIT was evaluated on UHMWPE …

Impacts Of White-Tailed Deer Grazing On Spring Wildflower Communities, Faye Frankland

Masters Theses

High deer densities on state forests and nature preserves throughout Illinois have prompted concerns that deer are impacting the growth, survival, and reproduction of spring-flowering herbaceous plants. I investigated the impacts of white-tailed deer (Odocoileus virginianus) on the herbaceous vegetation, particularly spring wildflowers, at Beall Woods Nature Preserve (BWNP). BWNP was selected as the site for this study because it supports a diverse community of spring wildflowers and a large deer population. The objectives for this study were to: (1) quantify the extent of deer foraging on representative spring-flowering plant species at Beall Woods Nature Preserve, (2) investigate the effects …
