Estimating Population Parameters Of The Louisiana Black Bear In The Upper Atchafalaya River Basin, 2011 University of Tennessee, Knoxville
Estimating Population Parameters Of The Louisiana Black Bear In The Upper Atchafalaya River Basin, Carrie Lynne Lowe
In 1992, the Louisiana black bear (Ursus americanus luteolus) was granted threatened status under the Endangered Species Act primarily because of extensive habitat loss and fragmentation. Currently, the Louisiana black bear is restricted to 3 relatively small, disjunct breeding subpopulations located in the Tensas River Basin of northeast Louisiana, the upper Atchafalaya River Basin (ARB) of south-central Louisiana, and coastal Louisiana. The 1995 Recovery Plan mandates research to determine the viability of the remaining subpopulations. I conducted a capture-mark-recapture study during 2007–2009 to estimate population parameters for the ARB bear subpopulation by collecting hair samples (n = 2,977) from ...
Design And Synthesis Of Metabolically Stabilized Lipid Probes For The Investigation Of Protein–Lipid Binding Interactions, 2011 University of Tennessee - Knoxville
Design And Synthesis Of Metabolically Stabilized Lipid Probes For The Investigation Of Protein–Lipid Binding Interactions, Ashdeep Kaur Rajpal
Protein–lipid binding interactions play crucial roles in various physiological and pathological processes, making it very important to study these interactions at the molecular level. However, investigation of these interactions is complicated by several issues, including the inherent complexity of membranes as well as the diverse mechanisms by which proteins interact with the membrane surfaces. As a result, many of these interactions remain poorly characterized. Synthetic probes are useful tools employed for studying protein–lipid binding interactions. This thesis will detail the design and synthesis of metabolically stabilized analogues of various signaling lipids, which mimic the natural species and are ...
Allometric Scaling Of Dietary Linoleic Acid On Changes In Tissue Arachidonic Acid Using Human Equivalent Diets In Mice, 2011 University of Tennessee, Knoxville
Allometric Scaling Of Dietary Linoleic Acid On Changes In Tissue Arachidonic Acid Using Human Equivalent Diets In Mice, Kylie A Weldon
The ability to extrapolate nutritional intervention data from experimental rodent models to humans requires standardization of dietary design. The inability to translate the level of nutrients from animal models to humans has contributed to contradictory findings between species. It is hypothesized that dietary linoleic acid (LA) promotes chronic and acute diseases by enriching tissues with arachidonic acid (AA), its downstream metabolite. However, levels of LA in rodent diets are notoriously erratic making interspecies comparisons unreliable. Therefore, the ability to extrapolate the biological effects of dietary LA from experimental rodents to humans necessitates an allometric scaling model that is rooted within ...
Causes, Extent, And Consequences Of Lead-Pellet Ingestion By Chukars (Alectoris Chukar) In Western Utah: Examining Habitat, Search Images, And Toxicology, R. Justin Bingham
All Graduate Theses and Dissertations
Lead ingestion adversely affects humans and over 130 species of wildlife. Wild chukars (Alectoris chukar) are documented to ingest lead, but the causes and consequences of this ingestion are poorly understood. The objectives of this research were to 1) examine the influence of habitat use, the hunting season, and seasonal climate on the extent and severity of lead ingestion by chukars in western Utah, 2) assess the effects of habitat use, feeding behaviors, and lead density on the causes of lead-pellet ingestion in captive and wild chukars, and 3) investigate the consequences of lead-pellet ingestion in captive chukars as a ...
Eugenics And Modern Biology: Critiques Of Eugenics, 1910-1945, 2011 Washington University in St Louis
Eugenics And Modern Biology: Critiques Of Eugenics, 1910-1945, Garland E. Allen
Biology Faculty Publications & Presentations
Eugenics in most western countries in the first four decades of the twentieth century was based on the idea that genes control most human phenotypic traits, everything from physical features such as polydactyly and eye color to physiological conditions such as the A-B-O blood groups to mental and personality traits such as “feeblemindedness”, alcoholism and pauperism. It assessing the development of the eugenics movement – its rise and decline between 1900 and 1950 – it is important to recognize that its naïve assumptions and often flawed methodologies were openly criticized at the time by scientists and non-scientists alike. This paper will present ...

We report evidence that Amblyomma maculatum tick populations are well established in southeastern Virginia. We found that 43.1% of the adult Gulf Coast ticks collected in the summer of 2010 carried Rickettsia parkeri, suggesting that persons living in or visiting southeastern Virginia are at risk for infection with this pathogen.
The Effects Of Bisphenol A On Adipose Tissue Development, Metabolism, And Endocrine Function And The Role It May Play In The Development Of Obesity, 2011 University of Tennessee, Knoxville
The Effects Of Bisphenol A On Adipose Tissue Development, Metabolism, And Endocrine Function And The Role It May Play In The Development Of Obesity, Brantley Nelson Wyatt
While diet and sedentary lifestyle remain important factors in the development of obesity, recent findings have shown the possible involvement of environmental obesogens, chemicals that can disrupt homeostatic energy balance and increase adiposity. Bisphenol A (BPA) is a compound used in the manufacturing of plastics as a hardening agent and is ubiquitous in the environment due to its widespread use. BPA has been shown to be an endocrine disruptor through its ability to mimic estrogen, which is now known to play important roles in adipose tissue growth and metabolism. In fact, a small but compelling number of studies have shown ...
Functional Cloning And Characterization Of Antibiotic Resistance Genes From The Chicken Gut Microflora, 2011 University of Tennessee, Knoxville
Functional Cloning And Characterization Of Antibiotic Resistance Genes From The Chicken Gut Microflora, Wei Zhou
A recent study using human fecal samples in conjunction with a culture-independent approach revealed immense diversity of antibiotic resistance (AR) genes in the human gut microflora. We hypothesize that food animal gut microflora also contain diverse and novel AR genes which could contribute to the emergence and transmission of AR in pathogens important in animal and human health. To test this, we examined AR reservoir in chicken gut microflora using a metagenomic, functional cloning method. Total genomic DNA was extracted from individual cecal contents of two free range chickens and two conventionally raised chickens. The DNAs were physically sheered into ...
Climate Change And Community Dynamics: A Hierarchical Bayesian Model Of Resource-Driven Changes In A Desert Rodent Community, Glenda M. Yenni
All Graduate Plan B and other Reports
Predicting effects of climate change on species persistence often assumes that those species are responding to abiotic effects alone. However, biotic interactions between community members may affect species’ ability to respond to abiotic changes. Latent Gaussian models of resource availability using precipitation and NDVI and accounting for spatial autocorrelation and rodent group-level uncertainty in the process are developed to detect differences in seasons, groups, and the experimental removal of one group. Precipitation and NDVI have overall positive effects on rodent energy use as expected, but meaningful differences were detected. Differences in the importance of seasonality when the dominant group was ...
Evaluation Of Delivery Conditions For Cutaneous Plasmid Electrotransfer Using A Multielectrode Array, 2011 Old Dominion University
Evaluation Of Delivery Conditions For Cutaneous Plasmid Electrotransfer Using A Multielectrode Array, Bernadette Ferraro, Loree C. Heller, Yolmari L. Cruz, Siqi Guo, Amy Donate, Richard Heller
Electroporation (EP) is a simple in vivo method to deliver normally impermeable molecules, such as plasmid DNA, to a variety of tissues. Delivery of plasmid DNA by EP to a large surface area is not practical because the distance between the electrode pairs, and therefore the applied voltage, must be increased to effectively permeabilize the cell membrane. The design of the multielectrode array (MEA) incorporates multiple electrode pairs at a fixed distance to allow for delivery of plasmid DNA to the skin, potentially reducing the sensation associated with in vivo EP. In this report, we evaluate the effects of field ...
Hermetic On-Farm Storage For Maize Weevil Control In East Africa, 2011 Iowa State University
Hermetic On-Farm Storage For Maize Weevil Control In East Africa, Ali Yakubu, Carl J. Bern, Joel R. Coats, Theodore B. Bailey
Agricultural and Biosystems Engineering Publications
Maize (Zea mays L.) consumption makes up over half of daily caloric intake of persons in East Africa and adequate supply is necessary for food security for subsistence farmers, as well as for domestic stability. Hermetic post-harvest maize storage is an attractive non-chemical control strategy for maize weevil,Sitophilus zeamais (Motsch.), which is the principal cause of insect damage to stored maize grain. Laboratory experiments were conducted on instrumented hermetic and non-hermetic containers to measure effects of temperature (10 vs. 27°C) and maize moistures (6.3 to 16%) on maize weevil biology and mortality rate, and to quantify weevil ...
Effects Of Gypsy Moth Outbreaks On North American Woodpeckers, 2011 Old Dominion University
Effects Of Gypsy Moth Outbreaks On North American Woodpeckers, Walter D. Koenig, Eric L. Walters, Andrew M. Liebhold
Biological Sciences Faculty Publications
We examined the effects of the introduced gypsy moth (Lymantria dispar) on seven species of North American woodpeckers by matching spatially explicit data on gypsy moth outbreaks with data on breeding and wintering populations. In general, we detected modest effects during outbreaks: during the breeding season one species, the Red-headed Woodpecker (Melanerpes erythrocephalus), increased over pre-outbreak levels, while during the winter one species, the Yellow-bellied Sapsucker (Sphyrapicus varius), increased and one, the Downy Woodpecker (Picoides pubescens), decreased from pre-outbreak levels. Responses following outbreaks were similarly variable, and in general we were unsuccessful at predicting population responses to outbreaks from a ...
Development For The Past, Present, And Future: Defining And Measuring Sustainable Development, 2011 University of Rhode Island
Development For The Past, Present, And Future: Defining And Measuring Sustainable Development, Max Cantor
Senior Honors Projects
In 1987, the United Nations released the Brundtland Report, which defined sustainable development as “development which meets the needs of the present without compromising the ability of future generations to meet their own needs.” While this definition provides a relatively stable theoretical base from which development economists and political scientists can begin to tackle issues surrounding sustainable development, the inherently amorphous nature of this definition has also created a fair amount of ambiguity in both the economic literature surrounding sustainable development and the subsequent attempts by economists to measure it.
Historically, those interested in the science of development have typically ...
The Importance Of Undecideds In The Evolution Vs. Creationism Debate, 2011 University of Rhode Island
The Importance Of Undecideds In The Evolution Vs. Creationism Debate, Seth Steinman
Senior Honors Projects
As a scientific theory, evolution has as much empirical support for its core assertions as the heliocentric universe theory or the belief that the Earth is round. Despite a unanimous consensus in the scientific community about evolution’s validity, the General Social Survey (GSS) consistently reports that 85 percent of Americans are either undecided or do not believe in evolution.
This divide between evolutionists, led by scientists, and creationists, led by religious leaders, has enormous scientific and political implications, which include funding for basic scientific research, acting to stop global warming, and what schools should be teaching our children.

Heartworm in Canines
Faculty Sponsor: Darlene Jones, DVM, Animal Science
Each year thousands of dogs in the United States become infected with heartworm, which is caused by Dirofilaria immitis. D. immitis is a parasite that is transmitted to dogs via a bite by an infected mosquito. Nine of the seventy competent mosquito species reside in Rhode Island. The true incidence of D. immitis is unknown. Current incidence maps are derived from data generated at veterinary clinics and do not include shelter dogs. The objective of this study is twofold: to determine the prevalence of D. immitis in shelter ...

Influence Of Ensiling Time And Inoculation On Alteration Of The Starch-Protein Matrix In High-Moisture Corn, 2011 University of Wisconsin-Madison
Influence Of Ensiling Time And Inoculation On Alteration Of The Starch-Protein Matrix In High-Moisture Corn, P. C. Hoffman, N. M. Esser, R. D. Shaver, W. K. Coblentz, Marvin Paul Scott, A. L. Bodnar, R. J. Schmidt, R. C. Charley
The fates of hydrophobic zein proteins, which encapsulate corn starch to create vitreous endosperm, have not been investigated in high-moisture corn (HMC). To assess influences of ensiling time and inoculation on zein proteins in HMC, quadruplicate samples of 2 random corn hybrids (A and B), containing 25.7 and 29.3% moisture, were ground, inoculated with (I) or without 600,000 cfu/g of Lactobacillus buchneri 40788 (Lallemand Animal Nutrition, Milwaukee, WI), and ensiled for 0, 15, 30, 60, 120, and 240 d. Nutrient composition [crude protein (CP), starch, acid detergent fiber, and neutral detergent fiber], fermentation (pH, lactate, and ...

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
PURPOSE. To define the contributions of the beaded filament (BF), a lens-specific intermediate filament (IF), to lens morphology and biomechanics.
METHODS. Wild-type and congenic CP49 knockout (KO) mice were compared by using electrophysiological, biomechanical, and morphometric approaches, to determine changes that occurred because of the absence of this cytoskeletal structure.
RESULTS. Electrophysiological assessment established that the fiber cells lacking the lens-specific IFs were indistinguishable from wild-type fiber cells. The CP49 KO mice exhibited lower stiffness, and an unexpected higher resilience than the wildtype lenses. The absence of these filaments resulted in lenses that were smaller, and exhibited a higher ratio ...
