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 …

A Sketch-Based Language For Representing Uncertainty In The Locations Of Origin Of Herbarium Specimens, Barry Kronenfeld, Andrew Weeks

Faculty Research and Creative Activity

Uncertainty fields have been suggested as an appropriate model for retrospective georeferencing of herbarium specimens. Previous work has focused only on automated data capture methods, but techniques for manual data specification may be able to harness human spatial cognition skills to quickly interpret complex spatial propositions. This paper develops a formal modeling language by which location uncertainty fields can be derived from manually sketched features. The language consists of low-level specification of critical probability isolines from which a surface can be uniquely derived, and high-level specification of features and predicates from which low-level isolines can be derived. In a case …

Relative Allelopathic Potential Of Invasive Plant Species In A Young Disturbed Woodland, Nikki Pisula, Scott Meiners

Faculty Research & Creative Activity

Invasive plant species are often more successful within introduced areas when compared to their natural ranges. Allelopathy has been suggested as a potential mechanism for this success because invasive plants frequently establish monocultures and may produce allelochemicals evolutionarily novel to the recipient community. However, species are typically tested in isolation making the relative strength of allelopathy difficult to assess. We conducted laboratory bioassays for 10 co-occurring non-native species to determine the relative strength of their allelopathic potential. These species represented a suite of successful invaders within a young forest and were from a variety of plant life forms: trees, lianas, …

Allelopathic Effects Of Goldenrod Species On Turnover In Successional Communities, Nikki Pisula, Scott Meiners

Faculty Research & Creative Activity

While goldenrod species are often found to be allelopathic in laboratory settings, its importance in controlling plant community dynamics has been much more difficult to assess. We designed a study to determine whether allelopathy is related to the success of goldenrods in abandoned agricultural land. To accomplish this, we conducted laboratory bioassays for six co-occurring goldenrod species and compared these results to the cover and impacts of these species in the field. We determined the germination responses of two target species to a gradient of leaf extract concentrations to assess the allelopathic potential of these goldenrods. We also used long-term …

Spatiotemporal Dynamics Of Lianas During 50 Years Of Succession To Temperate Forest, Laura Ladwig, Scott 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) …

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 …

Surveys Of Stylisma Pickeringii Var. Pattersonii (Convolvulaceae), Its Associated Plant Species, And Its Insect Visitors, Ann E. Claerbout, Brent L. Todd, Janice M. Coons, Henry R. Owen, Donald W. Webb, John E. Ebinger, William E. Mcclain

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 …

From Viruses To Russian Roulette To Dance: A Rhetorical Critique And Creation Of Genetic Metaphors, Marita Gronnvoll

Faculty Research and Creative Activity

This essay critiques and creates metaphoric genetic rhetoric by examining metaphors for genes used by representatives of the lay American public. We assess these metaphors with a new rhetorical orientation that we developed by building onto work by Robert Ivie and social scientific qualitative studies of audiences. Specifically, our analysis reveals three themes of genetic metaphors, with the first two appearing most frequently: 1) genes as a disease or problem 2) genes as fire or bomb, and 3) genes as gambling. We not only discuss the problems and untapped potential of these metaphors, but also we suggest metaphorically understanding genes …

Liana Host Preference And Implications For Deciduous Forest Regeneration, Laura M. Ladwig, Scott J. Meiners

Faculty Research & Creative Activity

Lianas have the potential to shape forest communities and alter forest regeneration. However, impacts of lianas on forest regeneration, particularly in temperate forests, are largely unstudied. To understand potential liana impacts on the community we need to first know the location and intensity of liana burdens on host trees. We examined liana-tree host references within a series of young regenerating deciduous forests in the Piedmont region of New Jersey, USA. Established trees ($ 5 cm dbh) and the lianas associated with each tree were surveyed in 2008. The five most abundant liana species were Celastrus orbiculatus, Lonicera japonica, Parthenocissus quinquefolia, …

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 …

Feathers As Bioindicators Of Pcb Exposure In Clapper Rails, Jay W. Summers, Karen F. Gaines, N. Garvin, Warren L. Stephens Jr., James C. Cumbee Jr., Gary L. Mills

Faculty Research & Creative Activity

In this study we used feathers to biomonitor exposure to the polychlorinated biphenyl (PCB) Aroclor 1268 congener mixture in clapper rails (Rallus longirostris). This species has been used as an indicator species of environmental damage for the LCP superfund site located in Brunswick, GA, USA which is contaminated with Aroclor 1268, a congener mixture that has been used in limited amounts elsewhere and therefore can be used as a contaminant marker. The Aroclor 1268 congener mixture, including congener profiles, were quantified in feathers using gas chromatography (GC). Concurrently, each sample was quantified for the total Aroclor 1268 congener mixture using …

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 …

It's Not Catharsis, It's Cognition: A New Approach To Emotion In Composition, Caronia (Nia) Klein

Masters Theses

Therapeutic writing, or writing as a method of emotional healing, seeks to facilitate psychological healing through self-discovery as a result of analyzing, interpreting, and making conclusions about challenging life experiences. Likewise, in composition theory, expressivist, feminist, and collaborative pedagogies advocate the empowerment of students through discovery and articulation of voice as a way to make meaning and develop as persons and students. Both approaches to writing foreground the use of personal experience as a way to process the external world through the emotional landscape of the writer, yet critics ofemotionally expressive writing decry its usefulness to composition pedagogy because of …

Genre Awareness In The Writing Center, Ashok Bhusal

Masters Theses

This thesis explores how genre theory is represented in writing center scholarship and practice by analyzing tutor training textbooks and also doing a case study of the EIU Writing Center to examine how genre awareness is perceived by writing consultants. This study concludes that increased awareness of genre features should influence the practice of writing consultants and writing centers. Based on the two surveys from my case study, the EIU Writing Center consultants did not appear to have a strong understanding of genre theory since their practicum course (English 5500) and tutor training textbooks have not explicitly provided them with …

War And The Sentimental Past: Memory And Emotion In The Aftermath Of The Franco-Prussian War, Chad R. Cussen

Masters Theses

This thesis argues that the Franco-Prussian War provoked strong emotional responses that were encoded in the memory of the war. The management of this emotional response represented an important aspect for the establishment of the Third Republic's legitimacy. By uniting French citizens through a public memory of the warby means of commemorations, funerals, and narratives among others-the Third Republic fostered an intense national consciousness that emerged as a feature of French identity. In contrast to Eugen Weber's influential work Peasants Into Frenchmen, which emphasizes the development of "Frenchness" through interactions in social institutions such as the military and the educational …

Gender Identity Development In Male Student Leaders At A Midwestern University, Kolin R. Straub

Masters Theses
