Predation Rates On Real And Artificial Nests Of Grassland Birds, William Davison, Eric 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 …

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

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 …

A Component Analysis Of Nondirective Play Therapy, Jane E. Wilson

Masters Theses

We evaluated the effects of nondirective play therapy on the inappropriate play of three developmentally normal children with conduct problems . Specifically, we examined the effects of attention (contingent vs noncontingent) and the play environment (enriched vs impoverished) using a reversal design. Our goal was to isolate one of these two variables as the primary effective component of nondirective play therapy for a particular child. For two subjects, attention remained contingent upon inappropriate play across conditions and the play environment was manipulated. Inappropriate play increased for one of these participants in an impoverished environment. For the third participant, an actual …

Male Sexual Behavior: Revisiting The Eiu Sexual Experience Survey And Report, Justin W. Freeman

Masters Theses

The EIU Sexual Experiences Survey of 1989 was given to 1693 Eastern undergraduate students in order to determine the incidence rate of sexual assault on campus. The survey report consisted of descriptive findings only, leaving future correlational research to answer any questions that remained. This study designated 664 male survey respondents with the Illinois legal classification system, and analyzed the demographics of the men surveyed to find any correlational relationships. No meaningful correlational relationships were found across the conditions of perpetrator and non-perpetrator for the male survey respondents.

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 …

Does Creatine Supplementation Increase Muscle Strength In Women?, Tricia Cross

Masters Theses

The purpose of this study was to see if creatine supplementation increased muscular strength in women. Ten females were assigned to either a creatine (CG) or a placebo (PG) group with five subjects in each. 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 …

African American Poets Of The Vietnam War, Megan Guernsey

Masters Theses

Almost 6000 African American men gave their lives in the Vietnam War. While peaceful protests, voter registration drives, and racial confrontations occurred throughout the United States, the government continued to send young Black men to Southeast Asia to preserve the "freedom" of the Vietnamese people. The irony of this situation lies in the fact that these soldiers were asked to fight a War in the name of democracy, to kill in order to secure rights that they themselves were being denied. Although many Black Americans saw military service as a means of escaping poor ghetto life, they often were confronted …

The Noble Survivor And The Sublime Victim: A Study Of Two Hardy Heroines, Elizabeth-Jane And Tess, Wei Gao

Masters Theses

In his novel-writing career, Thomas Hardy created a host of female characters struggling to survive in nineteenth-century England. Whether center stage or in the background, these women embody Hardy's insights into the conditions of the female sex--their frailties, strength, miseries, dreams, and finally, their destinies. Throughout his career as a novelist, Hardy's representation of women has not been consistent. His earlier heroines--heroines in the novels preceding The Mayor of Casterbridge (1886)--are generally depicted as faulty characters eventually subdued or destroyed. In contrast, the later heroines are portrayed with increasing emphasis on their intellectual or mental traits and moral superiority. This …

Current Trends In Psychological Testing, Kimberle L. S. Crawford

Masters Theses

Discussions about the adequacy of psychological measurement and assessment can quickly become controversial therefore; I expect some strong reaction to portions of this manuscript. Debates about the usefulness of criticism of psychological testing are longstanding: Even early psychologists such as Cattell and Jastrow disagreed on this issue. To be clear, I do not believe that use of contemporary tests should cease. I share the view that "psychological tests often provide the fairest and most accurate method of making important decisions" (K. R. Murphy & Davidshoffer, 1988, p. xii).

My first purpose, then, is to provide a historical survey of relevant …

Aggressive Communication, Parental Communication, And Sibling Communication, Kristi K. Eustice

Masters Theses

The family is often seen as the center of instruction for children and the base for learning communication patterns. Aggressive communication is often seen in the family, especially as a parenting method. In this thesis, the current state of available literature on aggressive communication in the family is examined. This includes parenting styles, communication relationships between one parent and one child, and the negative effects verbal aggressive communication has on children. A t-test is used to research the responses of 100 students who have verbally aggressive parents. At 2.59, the t-test supports the hypothesis that parenting communication styles concerning aggressiveness …

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 …

Effects Of Leafy Spurge (Euphorbia Esula) Infestation On Breeding Birds Of The Sheyenne National Grassland, Nd, Daniel M. Scheiman

Masters Theses

Leafy spurge (Euphorbia esula) is an exotic invasive weed in the northern Great Plains. We examined the effects of leafy spurge infestation on densities and nest success of breeding birds in grasslands on the Sheyenne National Grassland (SNG), ND. We categorized spurge-infested grasslands into three levels of infestation, based on the area covered by spurge patches: (a) low (0-20%), (b) medium (20-60%) and, (c) high (> 60%). We surveyed 60 100-m radius circular plots (20 in each category), and searched for nests in three 16-ha plots (one in each category). There were no statistically significant differences in mean species richness …

Emergence And Reproductive Patterns In The Japanese Beetle, Popillia Japonica (Coleoptera: Scarabaeidae), Steven J. Van Timmeren

Masters Theses

Sex-biased emergence patterns are common in insects resulting in either protandry (males emerging before females) or protogyny (females emerging before males). The Japanese beetle, Popillia japonica Newman, has been shown to exhibit protandry but shows some characteristics of a protogynous species. For example, females mate and oviposit multiple times and this species displays last male sperm advantage. This study investigated the emergence and egg laying patterns of Japanese beetles in east-central Illinois. Although variation existed among study sites none showed protandry and overall they displayed protogyny. Females did not initiate oviposition until several days after emergence and the number of …

The Relationship Between Neurotic Perfectionism And Symptoms Of Eating Disorders In College-Age Women, Valerie L. Devillez

Masters Theses

This study was designed to examine the relationship between neurotic perfectionism and symptoms of eating disorders in college-age women. There is minimal published research addressing this relationship, and only one study has been conducted in which eating-disordered subjects were compared to non-eating-disordered subjects. Sixty-five female participants completed survey materials including the Eating Disorder Inventory-2 (EDI-2) and the Neurotic Perfectionism Questionnaire (NPQ.) Participants were recruited from the Pavilion, the Eastern Illinois University Counseling Center, and from introductory psychology classes at Eastern Illinois University. Results suggest that there is a direct relationship between neurotic perfectionism and symptoms of eating disorders in college-age …

The Effects Of Gender And Parental Marital Status On Late Adolescent Risk-Taking, Jeff Daugherty

Masters Theses

Risk taking behavior among the adolescent population has increased in recent years putting America's youth in danger of many detrimental outcomes. Many adolescents currently engage in behaviors that represent health risks as well as those that are potential criminal risk. This study attempted to assess late adolescent risk-taking as a function of gender and parental marital status. Similarly, the self-esteem of late adolescent participants was also measured within the contexts of gender and family status. This study provides partial support for the idea adolescents with divorced parents engage in a significantly greater amount of risk-taking behavior than those with married …

A Time Resolved Laser Spectroscopy Study Of Resonance Energy Transfer Between Tb(Iii) And An Organic Dye: 6-Hydroxy-5-[(2-Methoxy-5-Methyl-4-Sulfophenyl)Azo]-2-Naphthalenesulfonic Acid Disodium Salt, Ronald Wesley Tennis

Masters Theses

Intermolecular energy transfer is a process of crucial importance to photochemistry and photophysics. Complexed lanthanide ions are well suited as energy transfer donors because they display dependable absorption and luminescence qualities with narrow rare-earthion emission in addition to relatively long excited-state lifetimes.

This project used a pulsed nitrogen laser and high speed digital techniques to study energy transfer dynamics between excited state Tb(acac)₃ and an ionic organic dye called Red 40. Luminescence decay profiles of excited terbium atoms in the presence of the quencher were measured in both high and low viscosity solvents. The effects of solvent viscosity and …

Effects Of Apolipoprotein E On Olfactory Neuron Plasticity In Mice, Rafia Nisar

Masters Theses

Previous studies have shown that apoE is upregulated in injured nerves, and that it may participate in nerve regeneration by recycling lipids from the degenerating myelin sheath to axonal growth cones. However, these studies fail to differentiate apoE function in degeneration and regeneration, because of temporal juxtaposition of degeneration and regeneration in these models. In this study, we characterized the apoE expression during olfactory nerve regeneration in mice, which occurs over an extended seven week period. Olfactory nerves were lesioned in 2-3-month-old mice by intransal irrigation of Triton X-100. Following lesioning the olfactory bulbs were collected at 0, 3, 7, …

Relationship Between Protective Effects Of Estrogen, Apoe And Alzheimer's Disease, Sara M. Ludwig

Masters Theses

Alzheimer's disease (AD) is a neurodegerative disorder characterized by progressive memory loss and loss of cognitive function. The pathogenesis and progression of AD is poorly understood. Recently, several risk factors have been determined, however, how these risk factors function to induce AD onset has yet to be elucidated.

Apolipoprotein E genotype has been clearly demonstrated to be a risk factor for AD. The apoE2 and apoE3 isoforms appear to be protective against AD, whereas the apoE4 isoform has been implicated in the development of AD. The apoE4 allele works in a dosage-dependent fashion; that is, the greater the expression of …

Differences In The Dreaming Style Of Schizophrenic And Non-Schizophrenic Subjects Based On Subscales Of The Dreaming Style Questionnaire, Larry Knopp

Masters Theses

The differences in dreaming style between 25 participants diagnosed with schizophrenia and 90 participants comprising a control group were examined. A Dreaming Style Questionnaire (DSQ), was administered to each participant. Nine subscales of the DSQ were used to explore differences in dreaming style between these two groups. A significant difference (p <.003) was found for the familiarity of characters subscales, showing those diagnosed with schizophrenia report that the characters in their dreams are unfamiliar to them. Trends were noted for the subscales assertiveness, low involvement, participation, and bizarreness. Information processing, function of rapid eye movement (REM) sleep, and dreaming style, were reviewed. It is concluded that dreaming style differences are found between the two groups. The significance of dream research is that innovative treatment methods for common mental health issues are being implemented and are proving to exhibit benefits to the recipient. Hopefully, research will shed some light on the etiology of mental health disorders resulting in better treatment methods.

Prairie Analysis At Prairie Ridge State Natural Area, Jasper County, Il, Annette Kessler

Masters Theses

Five restored prairie sites at Prairie Ridge State Natural Area in Jasper County were studied during the growing season of 1998. These sites varied in age from two years to thirty years and in size from 4 acres to 10 acres. Key areas of data recorded were an overall and site specific vascular species lists, phenology of various species, and cover analysis of each site. Frequency cover and importance values of the taxa were determined using randomly located quadrats along line transects. Prairie quality of each site was determined, as well as a similarity index that compared the sites to …
