Gravesoil Microbial Community Structure During Carcass Decomposition, Amy E. Maile

Department of Entomology: Dissertations, Theses, and Student Research

Dead bodies placed on soil represent unique challenges for investigators. Although processes in soils can be used to estimate postmortem interval, we know very little about how carcasses and insects affect gravesoil microbial communities.

To address this, the current project was composed of two experiments. Experiment one was conducted to investigate the effect of surface type on carcass decomposition and evaluate soil ecology methods. Experiment two was conducted to investigate the presence of an insect population (Lucilia sericata Meigen) on gravesoil microbial communities. Both experiments were conducted in a laboratory setting using freshly killed mouse carcasses. Mouse carcasses were …

Habitat Use And Abundance Patterns Of Sandhill Cranes In The Central Platte River Valley, Nebraska, 2003–2010, Todd Joseph Buckley

School of Natural Resources: Dissertations, Theses, and Student Research

The Central Platte River Valley (CPRV) in Nebraska is an important spring stopover area for the midcontinent population of sandhill cranes. Alterations to crop rotation and loss habitat in the CPRV pose a risk to the population. Personnel drove designated routes in the CPRV from 2003–2010 to record the presence of cranes in agricultural fields and estimate abundance. I developed and evaluated models to predict habitat use and flock sizes. Alfalfa was predicted to receive the highest use followed by corn, soybeans, winter wheat, grassland, and shrubland. Use of all habitats and flock size increased as field area increased. Flock …

Magnetic Susceptibility As A Proxy For Investigating Microbially Mediated Iron Reduction, Farag M. Mewafy, Estella A. Atekwana, D. Dale Werkema, Lee D. Slater, Dimitrios Ntarlagiannis, Andre Revil, Magnus E. Skold, Geoffrey N. Delin

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

We investigated magnetic susceptibility (MS) variations in hydrocarbon contaminated sediments. Our objective was to determine if MS can be used as an intrinsic bioremediation indicator due to the activity of iron-reducing bacteria. A contaminated and an uncontaminated core were retrieved from a site contaminated with crude oil near Bemidji, Minnesota and subsampled for MS measurements. The contaminated core revealed enriched MS zones within the hydrocarbon smear zone, which is related to iron-reduction coupled to oxidation of hydrocarbon compounds and the vadose zone, which is coincident with a zone of methane depletion suggesting aerobic or anaerobic oxidation of methane is coupled …

Pparδ Regulates Satellite Cell Proliferation And Skeletal Muscle Regeneration, Alison R. Angione, Chunhui Jiang, Dongning Pan, Yong-Xu Wang, Shihuan Kuang

Department of Animal Sciences Faculty Publications

Peroxisome proliferator-activated receptors (PPARs) are a class of nuclear receptors that play important roles in development and energy metabolism. Whereas PPARδ has been shown to regulate mitochondrial biosynthesis and slow-muscle fiber types, its function in skeletal muscle progenitors (satellite cells) is unknown. Since constitutive mutation of Pparδ leads to embryonic lethality, we sought to address this question by conditional knockout (cKO) of Pparδ using Myf5-Cre/Pparδ^flox/flox alleles to ablate PPARδ in myogenic progenitor cells. Although Pparδ-cKO mice were born normally and initially displayed no difference in body weight, muscle size or muscle composition, they later developed metabolic syndrome, which …

A Bayesian Model For Gene Family Evolution, Liang Liu, Lili Yu, Venugopal Kalavacharla, Zhanji Liu

Biostatistics: Faculty Publications

Background

A birth and death process is frequently used for modeling the size of a gene family that may vary along the branches of a phylogenetic tree. Under the birth and death model, maximum likelihood methods have been developed to estimate the birth and death rate and the sizes of ancient gene families (numbers of gene copies at the internodes of the phylogenetic tree). This paper aims to provide a Bayesian approach for estimating parameters in the birth and death model.

Results

We develop a Bayesian approach for estimating the birth and death rate and other parameters in the birth …

Detection And Characterization Of A Distinct Bornavirus Lineage From Healthy Canada Geese (Branta Canadensis), Susan Payne, Lina Covaleda, Guo Jianhua, Seth Swafford, John A. Baroch, Pamela J. Ferro, Blanca Lupiani, J Jill Heatley, Ian Tizard

United States Department of Agriculture Wildlife Services: Staff Publications

Avian bornaviruses (ABV), identified in 2008, infect captive parrots and macaws worldwide. The natural reservoirs of these viruses are unknown. Reverse transcription-PCR (RT-PCR) was used to screen oropharyngeal/ cloacal swab and brain samples from wild Canada geese (Branta canadensis) for ABV. Approximately 2.9% of swab samples were positive for bornavirus sequences. Fifty-two percent of brain samples from 2 urban flocks also tested positive, and brain isolates were cultured in duck embryo fibroblasts. Phylogenetic analyses placed goose isolates in an independent cluster, and more notably, important regulatory sequences present in Borna disease virus but lacking in psittacine ABVs were …

Innate And Adaptive Immunity To The Nematode Strongyloides Stercoralis In A Mouse Model., Sandra Bonne-Annee, Jessica A. Hess, David Abraham

Department of Microbiology and Immunology Faculty Papers

Mice have been used to the study the mechanisms of protective innate and adaptive immunity to larval Strongyloides stercoralis. During primary infection, neutrophils and eosinophils are attracted by parasite components and kill the larvae by release of granule products. Eosinophils also function as antigen-presenting cells for the induction of a Th2 response. B cells produce both IgM and IgG that collaborate with neutrophils to kill worms in the adaptive immune response. Vaccine studies have identified a recombinant diagnostic antigen that induced high levels of immunity to infection with S. stercoralis in mice. These studies demonstrate that there are redundancies in …

A False Start In The Race Against Doping In Sport: Concerns With Cycling’S Biological Passport, Nicholas Hailey

Duke Law Journal

Professional cycling has suffered from a number of doping scandals. The sport’s governing bodies have responded by implementing an aggressive new antidoping program known as the biological passport. Cycling’s biological passport marks a departure from traditional antidoping efforts, which have focused on directly detecting prohibited substances in a cyclist’s system. Instead, the biological passport tracks biological variables in a cyclist’s blood and urine over time, monitoring for fluctuations that are thought to indirectly reveal the effects of doping. Although this method of indirect detection is promising, it also raises serious legal and scientific concerns. Since its introduction, the cycling community …

Arms Control And Proliferation Challenges To The Reset Policy, Stephen J. Blank Dr.

Books, Monographs & Collaborative Studies

The current U.S. reset policy with Russia involves efforts to blaze a path of mutual cooperation on arms control and proliferation. In arms control, we see determined administration attempts to promote greater nuclear reductions in the direction of nuclear zero, including reductions in tactical nuclear weapons. This necessarily leads Moscow to raise issues of missile defense in Europe that it vehemently opposes. This monograph analyzes Russia’s position on these arms control issues and examines the chances for the United States to achieve its arms control goals in the foreseeable future. It also looks at the Russian position with regard to …

Status Of Institutional Repositories In Asian Countries: A Quantitative Study, Mohammad Nazim, Bhaskar Mukherjee

Library Philosophy and Practice (e-journal)

With the development of information communication technologies, a number of alternative strategies to the traditional scholarly publishing system have been evolved. Among these, Open Access (OA) model which promise to be extremely advantageous to peers everywhere, especially to those who have acute shortage of resources for purchasing scholarly literature. The impetus of OA was boosted by the Open Society Institute (OSI) in a small meeting convened in Budapest on December 1-2, 2001. The purpose of the meeting was to accelerate progress in the international effort to make research literature in all academic fields freely available on the Internet (OAIS, 2002; …

Heritable Epigenetic Variation Among Maize Inbreds, Steve R. Eichten, Ruth A. Swanson, James C. Schnable, Amanda J. Waters, Peter J. Hermanson, Sanzhen Liu, Cheng-Ting Yeh, Yi Jia, Karla Gendler, Michael Freeling, Patrick S. Schnable, Matthew W. Vaughn, Nathan M. Springer

Department of Agronomy and Horticulture: Faculty Publications

Epigenetic variation describes heritable differences that are not attributable to changes in DNA sequence. There is the potential for pure epigenetic variation that occurs in the absence of any genetic change or for more complex situations that involve both genetic and epigenetic differences. Methylation of cytosine residues provides one mechanism for the inheritance of epigenetic information. A genome-wide profiling of DNA methylation in two different genotypes of Zea mays (ssp. mays), an organism with a complex genome of interspersed genes and repetitive elements, allowed the identification and characterization of examples of natural epigenetic variation. The distribution of DNA methylation …

Zap1 Control Of Cell-Cell Signaling In Candida Albicans Biofilms, Shantanu Ganguly, Andrew C. Bishop, Wenjie Xu, Suman Ghosh, Kenneth W. Nickerson, Frederick Lanni, Jana Patton-Vogt, Aaron P. Mitchell

Kenneth Nickerson Papers

Biofilms of Candida albicans include both yeast cells and hyphae. Prior studies indicated that a zap1/ mutant, defective in zinc regulator Zap1, has increased accumulation of yeast cells in biofilms. This altered yeast-hypha balance may arise from internal regulatory alterations or from an effect on the production of diffusible quorum-sensing (QS) molecules. Here, we develop biosensor reporter strains that express yeastspecific YWP1-RFP or hypha-specific HWP1-RFP, along with a constitutive TDH3-GFP normalization standard. Seeding these biosensor strains into biofilms allows a biological activity assay of the surrounding biofilm milieu. A zap1/ biofilm induces the yeast-specific YWP1-RFP reporter in a wild-type …

An Exploratory Study Of Indian Science And Technology Publication Output, G. Buchandiran

Library Philosophy and Practice (e-journal)

The contribution of a nation to research promotes the knowledge building process. Understanding the research contribution of a nation is the basic component in science policy. In reality, science auditing is a complex process. The science policy makers employ a large number of science indicators - not all are equally important. Metrics employed in this study are not comprehensive as they are limited to scientific publications. Science auditing is not confined to a small set of indicators. To arrive at a broad science policy, we need to use many other indicators.

High-Performance Affinity Chromatography And The Analysis Of Drug Interactions With Modified Proteins: Binding Of Gliclazide With Glycated Human Serum Albumin, Ryan Matsuda, Jeanethe Anguizola, K.S. Joseph, David S. Hage

David Hage Publications

This study used high-performance affinity chromatography (HPAC) to examine the binding of gliclazide (i.e., a sulfonylurea drug used to treat diabetes) with the protein human serum albumin (HSA) at various stages of modification due to glycation. Frontal analysis conducted with small HPAC columns was first used to estimate the number of binding sites and association equilibrium constants (K_a) for gliclazide with normal HSA and glycated HSA. Both normal and glycated HSA interacted with gliclazide according to a two-site model, with a class of high affinity sites (average K_a, 7.1-10 × 10⁴ M⁻¹) …

Extent Of Coterminous Us Rangelands: Quantifying Implications Of Differing Agency Perspectives, Matthew Clark Reeves, John E. Mitchell

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Rangeland extent is an important factor for evaluating critical indicators of rangeland sustainability. Rangeland areal extent was determined for the coterminous United States in a geospatial framework by evaluating spatially explicit data from the Landscape Fire and Resource Management Planning Tools (LANDFIRE) project describing historic and current vegetative composition, average height, and average cover through the viewpoints of the Natural Resources Inventory (NRI) administered by the Natural Resources Conservation Service and the Forest Inventory and Analysis (FIA) program administered by the US Forest Service. Three types of rangelands were differentiated using the NRI definition encompassing rangelands, afforested rangelands, and transitory …

Everybody’S Doin’ It (Right?): Neighborhood Norms And Sexual Activity In Adolescence, Tara D. Warner, Peggy C. Giordano, Wendy D. Manning, Monica A. Longmore

Department of Sociology: Faculty Publications

A neighborhood’s normative climate is linked to, but conceptually distinct from, its structural characteristics such as poverty and racial/ethnic composition. Given the deleterious consequences of early sexual activity for adolescent health and well-being, it is important to assess normative influences on youth behaviors such as sexual debut, number of sex partners, and involvement in casual sexual experiences. The current study moves beyond prior research by constructing a measure of normative climate that more fully captures neighborhood norms, and analyzing the influence of normative climate on behavior in a longitudinal framework. Using recently geo-coded data from the Toledo Adolescent Relationships Study …

Multiple Paternity Of Caretta Caretta Within The Northwestern Atlantic Ocean Population On Wassaw Island, Ga, Jacob Lasala

College of Graduate Studies: Theses & Dissertations

Characterizing the mating system of a species is important for understanding demography and population dynamics and can contribute information to conservation efforts. Mating systems can impact the ecology, evolution, effective population size and genetic variability of a species. Polyandry, resulting in multiple paternity can influence the maintenance of genetic variation within a population. Within Testudines, the frequency of multiple paternity varies extensively among species (0-100% of nests). Previous studies on the loggerhead turtle (Caretta caretta) have shown that within the large management unit of peninsular Florida, multiple paternity occurs in approximately 30% of nests. This study examines nests from the …
