Feral Hog Research In Western Louisiana: Expanding Populations And Unforeseen Consequences, Michael D. Kaller, James D. Hudson Iii, Eric C. Achberger, William E. Kelso Jan 2007

Feral Hog Research In Western Louisiana: Expanding Populations And Unforeseen Consequences, Michael D. Kaller, James D. Hudson Iii, Eric C. Achberger, William E. Kelso

Human–Wildlife Interactions

Hunter harvest data suggest that feral hog (Sus scrofa) populations in western Louisiana are increasing, and population control in this region is complicated by the mixing of feral and domestic free-ranged hogs. Aggressive management may be warranted as feral and domestic hogs appear to be having unexpected effects on their ecosystem. We present the results of 3 recent investigations of genetic source-tracking to link waterborne bacteria with bacteria from feral hogs. We integrate our most recent findings with data regarding: (1) water quality in a watershed without hog management and (2) aquatic biota of the same watershed. Hog …

Distribution And Disease Prevalence Of Feral Hogs In Missouri, R. Edwin Hartin, Mark R. Ryan, Tyler A. Campbell

Human–Wildlife Interactions

No attempts have been made to document the distribution of feral hogs (Sus scrofa) in Missouri. Also, antibody prevalence for pseudorabies virus and swine brucellosis have not been reported from Missouri. Our objectives were to characterize the current distribution of feral hogs in Missouri and to determine prevalence and distribution of feral hogs with antibodies against selected important diseases. We collected feral hog sighting data both from the public and Missouri Wildlife Services and Missouri Department of Conservation wildlife biologists. We determined prevalence of antibodies against pseudorabies virus, swine brucellosis, tularemia, and classical swine fever. From 2000 to …

Appreciating Feral Hogs: Extension Education For Diverse Stakeholders In Texas, Dale Rollins, Billy J. Higginbotham, Kenneth A. Cearley, R. Neal Wilkins Jan 2007

Appreciating Feral Hogs: Extension Education For Diverse Stakeholders In Texas, Dale Rollins, Billy J. Higginbotham, Kenneth A. Cearley, R. Neal Wilkins

Human–Wildlife Interactions

Texas harbors the largest population of feral hogs (Sus scrofa) in the United States, with populations estimated at >2 million. Depending on one’s perspective, feral hogs are either a pariah (from the farmer’s standpoint) or a popular sporting animal (from a hunter’s standpoint). As feral hogs increase in range and density, conflicts among stakeholders are sure to increase. Texas Cooperative Extension (TCE) initiated educational programs in 1991 to address concerns regarding the presence and management of feral hogs. Since that time, we have developed various workshops, symposia, and educational materials (e.g., print, videotape, and website) as means of …

A Landscape-Level Survey Of Feral Hog Impacts To Natural Resources Of The Big Thicket National Preserve, Pedro M. Chavarria, Roel R. Lopez, Gillian Bowser, Nova J. Silvy

Human–Wildlife Interactions

We conducted a survey of the impact of feral hog (Sus scrofa) on the natural resources of the Big Thicket National Preserve (BTNP), a unit of the National Park Service. We worked in 3 management units: Lance Rosier, Big Sandy, and Turkey Creek. Random stratified sampling was conducted to assess impacts from hog damage on resources by vegetation type at a landscape scale. Landscape features such as topography, soil moisture, soil type, and dominant vegetative cover types were used to predict hog damage. The overall damage to vegetation from hog rooting or wallowing averaged 28% within the 3 …

Intrafield Patterns Of Wildlife Damage To Corn And Soybeans In Northern Indiana, Travis L. Devault, James C. Beasley, Lee A. Humberg, Brian J. Macgowan, Mónica I. Retamosa, Olin E. Rhodes Jr. Jan 2007

Intrafield Patterns Of Wildlife Damage To Corn And Soybeans In Northern Indiana, Travis L. Devault, James C. Beasley, Lee A. Humberg, Brian J. Macgowan, Mónica I. Retamosa, Olin E. Rhodes Jr.

Human–Wildlife Interactions

Management programs aimed at reducing wildlife damage to row crops rely on information concerning the spatial nature of wildlife damage at local and landscape scales. In this study we explored spatial patterns of wildlife damage within individual corn and soybean fields by describing relationships between specific locations where wildlife damage was recorded and distances from such locations to various habitat types that presumably influenced animal abundance and movements in our study area. Using stratified random sampling, we conducted depredation surveys of 100 corn fields and 60 soybean fields from May through October both in 2003 and 2004 and recorded the …

Efficacy Of Cpth-Treated Egg Baits For Removing Ravens, Peter S. Coates, Jack O. Spencer Jr., David J. Delehanty Jan 2007

Efficacy Of Cpth-Treated Egg Baits For Removing Ravens, Peter S. Coates, Jack O. Spencer Jr., David J. Delehanty

Human–Wildlife Interactions

Human-altered landscapes have provided resource subsidies for common ravens (Corvus corax) resulting in a substantial increase in raven abundance and distribution throughout the United States and Canada in the past 25 years. Ravens are effective predators of eggs and young of ground-nesting birds. During 2002–2005, we tested whether chicken egg baits treated with CPTH (3-chloro-p-toluidine hydrochloride) could be used to manage raven numbers in an area where raven depredation was impacting sharp-tailed grouse (Tympanuchus phasianellus columbianus) and greater sage-grouse (Centrocercus urophasianus) populations in Nevada. We performed multiple raven surveys at a treatment site and …

Crop Diversification Leads To Diverse Bird Problems In Hawaiian Agriculture, Marni E. Koopman, William C. Pitt Jan 2007

Crop Diversification Leads To Diverse Bird Problems In Hawaiian Agriculture, Marni E. Koopman, William C. Pitt

Human–Wildlife Interactions

Over the last 20 years, Hawaii’s agriculture has shifted from a focus on sugar cane (Saccharum officinarum) and pineapples (Ananas comosus) produced on large farms to a diverse array of products produced on a multitude of smaller farms. This dramatic shift in production, in addition to the introduction of many new avian species, has resulted in a concomitant change in the problems faced by agriculture. We surveyed farmers to determine the extent of bird damage to crops, the species responsible, the crops most vulnerable, and control methods employed. Bird problems varied by island, but cardinals ( …

Hazing Of Canada Geese Is Unlikely To Reduce Nuisance Populations In Urban And Suburban Communities, Robin A. Holevinski, Paul D. Curtis, Richard A. Malecki Jan 2007

Hazing Of Canada Geese Is Unlikely To Reduce Nuisance Populations In Urban And Suburban Communities, Robin A. Holevinski, Paul D. Curtis, Richard A. Malecki

Human–Wildlife Interactions

Growing populations of resident Canada geese (Branta canadensis) have caused increased nuisance problems in urban and suburban communities. Hazing, or persistent harassment, is often recommended as a nonlethal management strategy to alleviate these problems. Does hazing simply cause a local redistribution of birds, or can it solve nuisance problems by pushing geese to rural areas where hunting mortality could reduce the population? To answer this question, we marked 368 adult and 400 juvenile geese with leg bands in 1 urban and 1 suburban community in western New York State during June 2002 and 2003. This sample included 30 …

Use Of Decoy Traps To Protect Blueberries From Juvenile European Starlings, Michael R. Conover, Richard A. Dolbeer Jan 2007

Use Of Decoy Traps To Protect Blueberries From Juvenile European Starlings, Michael R. Conover, Richard A. Dolbeer

Human–Wildlife Interactions

Fruit consumption by large flocks of juvenile European starlings (Sturnus vulgaris) is a serious problem for growers of strawberries, grapes, apples, cherries, blueberries, and other small fruit. This study examined if numbers of juvenile European starlings foraging in blueberry orchards could be reduced by catching them in decoy traps and relocating the birds elsewhere. From late July through August of 1989, 620 juvenile starlings were captured in 2 decoy traps at a blueberry orchard in Connecticut. A similar number were caught during the same period in 1990. During these 2 years, numbers of juvenile starlings foraging daily in …

The Effect Of Α-Aminoadipate Δ-Semialdehyde Synthase Knockdown On The Lysine Requirement And Urate Oxidase Knockdown On Oxidative Stress In A Murine Hepatic Cell Line, Beth Marie Cleveland Jan 2007

The Effect Of Α-Aminoadipate Δ-Semialdehyde Synthase Knockdown On The Lysine Requirement And Urate Oxidase Knockdown On Oxidative Stress In A Murine Hepatic Cell Line, Beth Marie Cleveland

Graduate Theses, Dissertations, and Problem Reports (ETD)

The technique of RNA interference was applied in two different systems. In system I, RNA interference was used to knockdown expression of α-aminoadipate δ semialdehyde synthase (AASS). AASS is the bifunctional enzyme containing the lysine α-ketoglutarate reductase (LKR) and saccharopine dehydrogenase activities responsible for the first two steps in the irreversible catabolism of lysine. A rare disease in humans, familial hyperlysinemia, can be caused by very low LKR activity and, as expected, reduces the lysine “requirement” of the individual. This concept was recreated in a murine hepatic cell line (ATCC, FL83B) utilizing RNA interference to achieve AASS mRNA knockdown. Cells …

Exploring The Ligand Binding Site On The Dopamine Transporter By Photoaffinity Labeling And Site-Directed Mutagenesis, Maria Laura Parnas Jan 2007

Exploring The Ligand Binding Site On The Dopamine Transporter By Photoaffinity Labeling And Site-Directed Mutagenesis, Maria Laura Parnas

Theses and Dissertations

The dopamine transporter (DAT) is a neuronal presynaptic transmembrane protein that clears released dopamine (DA) from the synaptic space, regulating the neurotransmitter concentration and availability, DAT and the related serotonin (SERT) and norepinephrine (NET) transporters belong to the SLC6 family of Na+ and CI- dependent symporters, and are major targets for the action of several drugs, including the psychostimulant cocaine. DAT is predicted to possess 12 transmembrane spanning domains (TMs), with both N- and C-termini located intracellularly. Extensive research efforts to gain insight on the molecular aspects of DAT have been attempted, but the three-dimensional arrangement of the protein as …

Instead Of Erklären And Verstehen: William James On Human Understanding, David E. Leary Jan 2007

Instead Of Erklären And Verstehen: William James On Human Understanding, David E. Leary

Psychology Faculty Publications

Perhaps more than any other American psychologist and philosopher, William James (1842-1910) was intimately familiar with contemporary European thought and debate, including the discussion of Erklären and Verstehen advanced by Wilhelm Dilthey (1833-1911) and others around the turn of the twentieth century. Even before this discussion was initiated, James had been dealing with related issues, pondering alternative solutions, and formulating his own original views on human understanding. These views coalesced in a distinctive approach to cognition. Fundamental to this approach was a belief in possibility and probability as innate features of the physical as well as mental manifestations of the …

Age-Appropriate Programs: Best Practice: Effective Programs Are Designed To Match The Developmental Stages Of The Learner, Daphne Sewing, Allison Brody Jan 2007

Age-Appropriate Programs: Best Practice: Effective Programs Are Designed To Match The Developmental Stages Of The Learner, Daphne Sewing, Allison Brody

Education about the Environment

Children and adults learn in completely different ways. Too often, however, children’s programs are developed from an adult’s perspective, rather than that of a child. The best children’s environmental education programs are designed with children’s abilities, developmental needs, interests, and learning styles in mind. Different programs should be created to appropriately meet the needs of different age groups and their respective cognitive development, attention spans, coordination abilities, interests, and ways of interacting with nature.

Oxidative Dna Damage In Mild Cognitive Impairment And Late-Stage Alzheimer's Disease, Mark A. Lovell, William R. Markesbery Jan 2007

Oxidative Dna Damage In Mild Cognitive Impairment And Late-Stage Alzheimer's Disease, Mark A. Lovell, William R. Markesbery

Chemistry Faculty Publications

Increasing evidence supports a role for oxidative DNA damage in aging and several neurodegenerative diseases including Alzheimer's disease (AD). Attack of DNA by reactive oxygen species (ROS), particularly hydroxyl radicals, can lead to strand breaks, DNA–DNA and DNA–protein cross-linking, and formation of at least 20 modified bases adducts. In addition, α,β-unsaturated aldehydic by-products of lipid peroxidation including 4-hydroxynonenal and acrolein can interact with DNA bases leading to the formation of bulky exocyclic adducts. Modification of DNA bases by direct interaction with ROS or aldehydes can lead to mutations and altered protein synthesis. Several studies of DNA base adducts in late-stage …

Improved Nitrate Sensing Using Ion Selective Electrodes Based On Urea–Calixarene Ionophores, Benjamin Schazmann, Dermot Diamond Jan 2007

Improved Nitrate Sensing Using Ion Selective Electrodes Based On Urea–Calixarene Ionophores, Benjamin Schazmann, Dermot Diamond

Articles

Urea–calix[4]arenes 1 and 2 were synthesised and incorporated into ISE membranes for assessment as sensors for inorganic anions in water. 1 revealed a strong response to all anions following the Hofmeister selectivity order. For ISEs of 2, the response to a portion of the anion series was suppressed, increasing the margin of selectivity of nitrate over chloride, a common interferant of nitrate in fresh and marine water samples. The performance of ISEs containing 2 was compared to commercially available alkylammonium nitrate ion-exchange salts used for nitrate sensing. Our ISEs performed favourably in terms of sensitivity, linear range and LOD performing …

Ecological Succession On Abandoned Roads In The Lake Mead National Recreation Area, John Daniel Bolling Jan 2007

Ecological Succession On Abandoned Roads In The Lake Mead National Recreation Area, John Daniel Bolling

UNLV Retrospective Theses & Dissertations

With the intent of describing the processes controlling desert succession, I examined soil and vegetation dynamics along a chronosequence of abandoned roads in the Mojave Desert. Early successional shrubs dominated younger roads; the long-lived Larrea tridentata dominated older roads. Soils on roads were more compacted, and had higher bulk densities, lower available phosphorus and lower total nitrogen than adjacent control areas. No soil factors changed significantly with road age, perhaps due to the observed high spatial heterogeneity. Fertile island development was also slow to occur on roads. Roads created by surface vehicular traffic had higher levels of shrub cover, soil …

Determining The Fate And Transport Of The Acrylamide Monomer (Amd) In Soil And Groundwater Systems, Todd James Arrowood Jan 2007

Determining The Fate And Transport Of The Acrylamide Monomer (Amd) In Soil And Groundwater Systems, Todd James Arrowood

UNLV Retrospective Theses & Dissertations

Acrylamide (AMD) is a known animal and suspected human carcinogen and is used to produce polyacrylamide (PAM), which has been proposed as a technology for seepage control in unlined water delivery canals. Previous studies have not quantified the fate and transport of AMD in soil and groundwater systems. In this study, batch experiments and soil column tests (with and without microbial degradation) were conducted on three materials (control sand, gravelly sand and loam soil) to determine the Kd, retardation factor, the form of the sorption isotherm, and determine microbial degradation rates. Soil core tests from samples collected in canals were …

Prostate Volume Delineation And Seed Localization Using A 3-T Magnetic Resonance Spectrometer, Jason Eric Davis Jan 2007

Prostate Volume Delineation And Seed Localization Using A 3-T Magnetic Resonance Spectrometer, Jason Eric Davis

UNLV Retrospective Theses & Dissertations

With approximately one in six men affected by prostate cancer at some point in their lives, effective treatment of the disease remains a focus of oncology research. Effective treatment using radiation requires the delivery of a significant dose to the prostate volume while sparing surrounding sensitive structures. Treatment success can then be determined by localization of the seeds following implantation and the calculation of a dose distribution across the target volume. Magnetic Resonance Imaging (MRI) yields images with soft tissue contrast that is superior to CT or ultrasound, but has been under-appreciated as a dosimetric tool due to the difficulty …

Identification And Interpretation Of Botanical Remains From Neolithic 'Ais Yiorkis, Cyprus, Leilani Espinda

UNLV Retrospective Theses & Dissertations

The botanical remains from the 2005 field season at 'Ais Yiorkis , Cyprus demonstrates a distinct economic assemblage that has yet to be identified in the Aceramic Neolithic of Cyprus. In addition to the unusually high proportions of two-grained einkorn and the low ratios of other plant parts, 'Ais Yiorkis is characterized by an atypical architectural phenomenon in the form of raised circular platform structures. Furthermore, the archeology is marked by a distinct lithic and groundstone tool industry as well as a massive faunal assemblage, which includes the presence of cattle, previously rare in the Neolithic. Together with the archaeology …

Bodily Poetics: The Rhetorical Politics Of The Self, Allison Renee Kaminsky Jan 2007

Bodily Poetics: The Rhetorical Politics Of The Self, Allison Renee Kaminsky

UNLV Retrospective Theses & Dissertations

This thesis will examine different ways people consciously manipulate their bodies in order to express selfhood, articulate identities, fulfill desires, and signal social and political commitments. The major premise of this research is that bodies are rhetorically constructed through a series of fundamental assumptions about selfhood, social ideals and acceptability, and political struggle. This paper argues that there are no a priori distinctions between the various practices and meanings of body modification. The way we think about body modification is based on a series of assumptions that define each practice. This project will look at three different groupings of modification …
