Strength In Numbers: Setting Quantitative Criteria For Listing Species Under The Endangered Species Act, Kalyani Robbins

Akron Law Faculty Publications

My primary thesis is that the Fish & Wildlife Service and the National Marine Fisheries Service need to set quantitative criteria for listing species under the Endangered Species Act in order to promote consistency, transparency, and efficiency. I suggest a model for doing so, the use of which would create an opportunity to move beyond the political quagmire surrounding the selection of vulnerable species for preservation. Like my other environmental scholarship, the article merges scientific research in the field of conservation biology with legal analysis. With the status quo, listing decisions often turn on wildly different factors, including some not …

Where We Can't Follow: A Collection Of Short Stories, Megan Holt

Masters Theses

This humorous collection of short stories revolves around the lives of the patrons and employees who frequent the bars. When men and women come together to congregate over drinks, their conversations turn towards every topic except the important aspects of their various relationships. As underlying conflicts rise to the surface, and the situations become more comical, the characters are faced with a brief epiphany about the true nature of their personalities. Rather than becoming inspired by these moments of clarity, these men and women resist the urge to change. The liquor continues to flow, inhibitions flounder, and these characters hurtle …

Dynamics Of Aggregation Formation In Japanese Beetles, Popillia Japonica, Katelyn A. Kowles

Masters Theses

For most insect aggregations to form, they need to be started by an initial individual (the pioneer) andjoined by later individuals (the joiners). Pioneers and joiners may differ with regard to characteristics such as sex and body size. We carried out three field experiments to examine the characteristics of Japanese beetles, Popillia japonica, pioneering and joining aggregations on host plants. Individual beetles were captured as they arrived on uninhabited grape plants, as well as plants designed to simulate aggregations with model beetles and feeding damage. For all experiments and treatments, the beetles arriving were significantly female-biased, with pioneer females having …

Cloning, Overexpression, Purification And Characterization Of Gcp Ii Homologous Metalloprotein From Caulobacter Crescentus, Dilani Nilushika Gigiriwala Gamage

Masters Theses

A novel zinc metalloprotease gene isolated from Caulobacter crescentus (CCM) was cloned and overexpressed in Escherichia coli. A protease database search using MEROPS predicted this protein is a homolog of Glutamate Carboxypeptidase II (GCP II), a zinc metalloprotease found in humans and many other organisms. GCP II is considered as a suitable target for treating stroke, neurological disorders and a biomarker for prostate cancer. Chromatographic purification of CCM produced pure protein in milligram quantities. Molecular weight detern1ination using MALDI-TOF showed 51,582 Da and the extinction coefficient was found to be 33,007 M"1cm·1. Metal analysis and substrate profiling showed neither sufficient …

Stability Of Heme Proteins: Cytochrome C And Horseradish Peroxidase, Mini Gupta

Masters Theses

A heme protein is a metalloprotein containing the heme prosthetic group. This prosthetic group is responsible for the wide range of biological functions found in heme proteins, from oxygen transport to electron transport. Moreover, heme proteins show a fascinating range of folding architectures, leading to their interest in research on structure-function relationships. The objective of this research in bioinorganic chemistry is to study the structural stability of two heme proteins, iron cytochrome c (Fecyt) and horseradish peroxidase (HRP). Absorbance spectroscopy is used to monitor the structural changes in the protein environment around the heme prosthetic group.

Electrochemical And Spectroscopic Characterization Of A Polypyridyl Ru(Ii) Complex Containing A Fused Alloxazine, Waynie Wilson Olaprath

Masters Theses

Phenanthroline pteridinedione (pptd) is an alloxazine derivative capable of 2e/ 2H+ transfer reactions. Coordination of pptd to a Ru(II) metal center allows for the synthesis of water-soluble metal complexes capable of being reduced by as many as 6 Hatoms making them candidates to be electrochemical mediators. This thesis describes the synthesis and characterization of pptd and [Ru(bpy)2(pptd)](PF6)2(b py = 2,2-bipyridine). The dipyrido[3,2-a: 1' ,2' -c] phenazine (d ppz) and [Ru(bpy)2(d ppz) ](PF6)2 are also synthesized and studied in order to distinguish the properties of the free and coordinated pteridinedione-based pptd ligand from the well-characterized phenazine based ligand.

Ecology And Impacts Of Lianas In Regenerating Forests, Laura Marie Ladwig

Masters Theses

Although they are important components of forest communities, the general ecology of temperate lianas, especially during forest regeneration, is largely unknown. The dependence of lianas on other plants for physical support makes them a potentially important driver of community dynamics. I examined current and past vegetation data from an old-field succession study in the Piedmont region of New Jersey, USA to determine the dynamics of liana expansion and their role in forest regeneration. Fifty years of vegetation data were utilized to determine community controls and population dynamics oflianas during expansion. Five lianas, Celastrus orbiculatus, Lonicera japonica, Parthenocissus quinquefolia, Toxicodendron radicans, …

Aging In The Mammalian Olfactory System, Stephen Clark

Masters Theses

The purpose of this investigation was to investigate genetic and age~related differences in the mammalian olfactory system. The molecule of interest is apolipoprotein E (apoE), a component oflipoprotein molecules which functions in the transport of cell membrane components (triglycerides, lipids, and cholesterol). Specifically in the nervous system, apoE is synthesized by glial cells that function in recycling dead nervous tissue components for delivery to growing or dividing neurons. ApoE is present in three protein isofon11s: apoE2, which has been associated with type III hyperlipoproteinemia; apoE3, rhe normal human isoforrn; and apoE4, which has been associated with Alzheimer's disease (AD). The …

Interaction Of Apoe With Estrogen In The Olfactory System During Nerve Maintenance And Recovery, Michael M. Tonsor Ii

Masters Theses

Estrogen replacement profoundly aids in nerve regeneration after injury in adult mammalian models. Estrogen replacement also protects against olfactory dysfunction in mammals. The mechanism underly1ng estrogen's neuroprotective effects remains ambiguous. My goal is to investigate and better clarify if apolipoprotein E (apoE ), a lipid transporting protein, is a critical intermediary to estrogen's effects on nerve maintenance and regeneration.

My hypothesis is that apoE is a mediator of estrogen's beneficial effects. This hypothesis is based on the following observations from previous studies. First, olfactory nerve regeneration was delayed in apoE-gene knockout (KO) mice as compared to wild type (WT) mice. …

Fragmentation Effects On Fitness In Five Common Prairie Species, Lydia Miramontes Loyd

Masters Theses

Midwest tallgrass prairies have suffered extensive habitat loss and as a result persist as isolated and highly fragmented remnants. In such small, isolated remnants, genetic drift and inbreeding depression can lead to a loss of genetic variation over time. Reduced genetic variation is often associated with reduced levels of growth, survival, and reproduction as well as increased susceptibility to stress. This study examined fitness traits of five common prairie species to determine whether plants in small fragmented remnants had reduced fitness as compared to those in a larger remnant. Five prairie species were chosen for this study based on their …

The Fate Of Salmonella Tennessee And Salmonella Typhimurium In Peanut Butter Subjected To Electron Beam Irradiation, Andrea Lynn Hvizdzak

Graduate Theses, Dissertations, and Problem Reports (ETD)

Peanut butter and peanut paste products were implicated as the vehicle of contamination in an outbreak of Salmonella Typhimurium that began in September 2008 and in the November 2006 outbreak of Salmonella Tennessee; therefore based on the apparent need for intervention measure, the purpose of this research was to evaluate the effectiveness of non-thermal electron beam irradiation for reduction of Salmonella serovars Tennessee (ATCC 10722) and Typhimurium (ATCC 14028) in creamy peanut butter. Each strain was studied independently. Peanut butter samples were inoculated with approximately 7.0 log CFU/g of Salmonella and exposed to e-beam doses ranging from 0--3.1 kGy. Doses …

Acidic Deposition Effects On Above- And Belowground Wood Biomass And Nutrient Status In A Young Hardwood Forest, Brittany Anne Johnson

Graduate Theses, Dissertations, and Problem Reports (ETD)

The impact of acid deposition on forest productivity has been studied extensively during the past 30 years. Mixed results abound due to variations in forest age, species composition, land use history, climate, and different experimental procedures. However, most results suggest alterations in productivity and nutrient status as a result of elevated acid deposition. The Long-Term Soil Productivity (LTSP) site in the Fernow Experimental Forest served as the study site; it was initiated with the purpose of observing the impact of forest management and air quality on biomass production and nutrient cycling (Adams et al. 2004). In its entirety, this experiment …

This study describes a multivariate model demonstrating how lifestyle behaviors and illness related factors work together to predict recurrent headache in an adolescent population.;Method. A descriptive, cross-sectional, secondary analysis using survey data from the National Longitudinal Study of Adolescent Health (Add Health) (1996) will be reported. Add Health is a large database providing a nationally representative …

Random Knn Modeling And Variable Selection For High Dimensional Data, Shengqiao Li

Graduate Theses, Dissertations, and Problem Reports (ETD)

High dimensional data is widely available in bioinformatics, chemometrics and other applications. For example, in gene expression experiments, tens of thousands of genes are probed. Phenotype data may be clinical data such as tumor types, or quantities measuring biological characteristics of a subject. While such high dimensional data can be readily generated, successful analysis and modeling of these data is highly challenging.;Random KNN, as proposed in this dissertation, is a novel generalization of traditional nearest-neighbor modeling. Random KNN consists of an ensemble of base k nearest-neighbor models, each taking a random subset of the input variables. A theoretical and empirical …

Nest Success, Nesting Habitat, & Nestling Feeding Rates Of Red-Headed Woodpeckers In East-Central Illinois, Nathan Cole Hudson

Masters Theses

The Red-headed Woodpecker (Melanerpes erythrocephalus) is a classic oak savanna species that has suffered significant population declines caused, in part, by extensive loss of savanna habitat and agricultural development. Despite consistent data that reveal a dramatic decline throughout much of their range, few studies have examined other possible explanations. In an effort to determine potential causes for their continued decline (as well as add to existing knowledge of nesting biology), we examined nest success and nesting micro-habitat features. We compared micro-habitat variables at: 1) golf and non-golf course sites, 2) successful and failed nest sites, and 3) nest and random …

Analysis Of Transcription Factor Promoter Binding In Rat Hepatoma/Fibroblast Hybrids, Jordan C. Angle

Masters Theses

When hepatomas (liver cancer cells) are fused with fibroblasts (undifferentiated body cells), there is complete extinguishing of all tissue-specific gene expression. Once it was discovered that many hybrid cell lines do not express needed transcription factors for liver-specific gene transcription, the factors were reintroduced and forced to express through the use of plasmids. Even if the two primary transcription factors were present in the system, downstream tissue-specific gene expression was not rescued. To examine potential mechanisms for the repression of liver-specific gene expression in hepatoma x fibroblast hybrid cells, chromatin immunoprecipitation (ChlP) was used. This procedure allows the liver-specific gene …

Long-Term Assessment Of Predatory Fish Removal On A Pond-Breeding Amphibian Community In Central Illinois, Lee M. Gross

Masters Theses

Habitat loss and fragmentation are important contributors to population declines in many species, so maintaining suitable habitat has become a priority for wildlife management. Removal of introduced fish can help restore suitable habitats for amphibian populations, although long-term assessments of such removals are lacking at the community level. In 2001, drift fences and pitfall traps were constructed around the majority of four ponds to monitor an amphibian community in a nature preserve in central Illinois. Rotenone™ was applied to ponds containing introduced fish in 2001, and again, in 2003. I collected data from 2005-2007 to determine the long-term impacts of …

Habitat Selection And Niche Partitioning Of Fox And (Sciurus Niger) And Gray (Sciurus Carolinensis) Squirrels In Charleston, Il, Katelyn Marti

Masters Theses

Two species of tree squirrels inhabit Charleston, IL; fox squirrels (Sciurus niger) and gray squirrels (Sciurus caro/inensis). Although these species are sympatric throughout much of the eastern U.S., urban settings are usually occupied by one or the other. In the few localities where they co-occur, little is known about how they partition habitat. Therefore, the objectives of my study were to determine: (1) the relative abundance of each species, (2) whether habitat use differs between species, (3) if habitat use shifts with season, time of day, domestic predator abundance, or mast availability, and (3) observe interspecific and intraspecific interactions. The …

Survival Strategies Of The Endangered Physaria Ludoviciana (Silvery Bladderpod; Brassicaceae), Marissa Catherine Jernegan Grant

Masters Theses

Physaria ludoviciana (Nuttal) O'Kane and Al-Shehbaz is an endangered species in Illinois and Minnesota sand prairies, but has many individual populations in western states. Areas where P. ludoviciana occurs have high summer temperatures, a sandy soil with low water holding capacity and high drainage, the frequent disturbance of blowing sand and little canopy vegetation, giving it a full sun environment. This habitat is where few other plants are able to establish, providing P. ludoviciana with little competition. Physaria ludoviciana exists in a niche where it is adapted and able to establish and persist. The focus of this study was to …

Factors Affecting Dietary Compliance In The Adolescent With Type 1 Diabetes, Maryjean K. Bargren

Masters Theses

The purpose of this study was to research adult persons with type 1 diabetes and determine what factors played a role in both compliance and non-compliance of their diabetes management as an adolescent. The purpose was also to determine what factors may have caused an adolescent to be non-compliant throughout their adolescent years but who in adulthood became compliant.

Managing diabetes throughout adolescence can be difficult with many changes occurring both hormonally and socially. A medium sized hospital in the Midwest was used to obtain participants for this study. Questionnaires were distributed to patients at their medical appointments. There were …

Faculty, Staff and Student Publications

Persistently low white blood cell count (WBC) and neutrophil count is a well-described phenomenon in persons of African ancestry, whose etiology remains unknown. We recently used admixture mapping to identify an approximately 1-megabase region on chromosome 1, where ancestry status (African or European) almost entirely accounted for the difference in WBC between African Americans and European Americans. to identify the specific genetic change responsible for this association, we analyzed genotype and phenotype data from 6,005 African Americans from the Jackson Heart Study (JHS), the Health, Aging and Body Composition (Health ABC) Study, and the Atherosclerosis Risk in Communities (ARIC) Study. …
