Eastern Spotted Skunk (Spilogale Putorius) At The Ouachita Mountains Biological Station, Polk County, Arkansas, L. M. Hardy

Journal of the Arkansas Academy of Science

A population of the eastern spotted skunk (Spilogale putorius) has been discovered at the Ouachita Mountains Biological Station in the Ouachita Mountains of Polk County, Arkansas. In 2010 a motion camera recorded a very brief infrared video of an animal that, after much study and conversation with other biologists, was concluded to be an eastern spotted skunk. Since that time the identification has been confirmed with at least 6 still photographs and one additional video that have been obtained from 2 other locations on the station. At least 2 or 3 individuals are present. All were photographed at night in …

Assessment Of The Modern Fish Assemblage In Mound Pond (Lonoke County) And Comparison With The Archeological Record, A. V. Fernando, M. A. Eggleton

Journal of the Arkansas Academy of Science

Mound Pound is a 56-ha oxbow lake of the Arkansas River. The lake has been disconnected from the Arkansas River main channel for over 2,500 years. The lake lies adjacent to the Toltec Mounds Archeological State Park, which contains the Toltec Mound Complex (3LN42). In October 2012, a multiple-gear sampling of the fish assemblage in Mound Pond was conducted using boat-mounted electrofishing, mini-fyke nets, and experimental gill nets. Across all gears, 501 fish specimens were collected and identified to species. Percent Similarity Index (PSI) and Shannon-Weiner Diversity Index (H') values were calculated using data from this survey and a previous …

Scarab Beetles (Coleoptera: Scarabaeidae) In The Dung Of Native Arkansas Mammals, J. B. Kelley, J. L. Hunt, M. B. Connior

Journal of the Arkansas Academy of Science

Dung beetles are important ecological components of natural ecosystems. One primary activity is the fragmentation and recycling of animal dung. Little is known about the ecological impact of beetles associated with the dung of mammals native to Arkansas. We surveyed the dung of native mammals within Arkansas to determine the species and distributional patterns associated with dung. We searched and collected beetles in situ from the dung or nests of native mammalian species within Arkansas. We also set simple pitfall traps using dung of various native Arkansas mammals as bait. Most of the beetles collected were common dung beetles. However, …

Ecological Effects And Genetic Diversity Of The Invading Rhizocephalan Parasite Loxothylacus Panopaei In The Flatback Mud Crab Eurypanopeus Depressus, Kathryn A. O'Shaughnessy

Electronic Theses and Dissertations

The rhizocephalan barnacle Loxothylacus panopaei (Gissler, 1884) is a parasite of xanthid crabs. Infection results in parasitic castration and anecdysis of the host. Loxothylacus panopaei is invasive to the US Atlantic coast. The parasite's range was expanded by introduction of infected crabs to Chesapeake Bay in the mid-1960s, and now extends from Long Island Sound, New York to Cape Canaveral, Florida. Monthly flatback mud crab (Eurypanopeus depressus Smith, 1869) collections over 13 months (January 2012-January 2013) at three South Carolina locations found an overall parasite prevalence of 24.2% (391 of 1,615), and provided the first reports of L. panopaei at …

Genetically Modified Myoglobin As A Mimic For Heme Enzymes, Subhash Chand

Chemistry & Biochemistry Dissertations - Archive

This study addresses the mechanistic relationships between formation of reactive oxygen species (ROS) and their catalytic oxidation functions in oxygenation and peroxygenation reactions in heme enzymes. Even though both cytochrome P450s (CYP P450s) and peroxidases have different catalytic activities, the involvement of common ROS (Compound 0 and Compound I) have been proposed. Therefore, to understand the generation and activation of peroxide to form ROS, genetically-engineered myoglobin (Mb) mutants were created by incorporating redox-sensitive 3-amino-L-tyrosine (NH2Tyr) or L-3, 4-dihydroxyphenylalanine (DOPA) into its active site. Distal His 64 replaced with redox amino acids mutant Mb showed excellent turnover rates for thioanisole and …

Evaluating The Use Of Autonomous Recording Units To Monitor Yellow Rails, Nelson's Sparrows, And Le Conte's Sparrows, Anna Marie Sidie-Slettedahl

Electronic Theses and Dissertations

Population status and habitat use of yellow rails (Coturnicops noveboracensis) (YERA), Nelson’s sparrows (Ammodramus nelsoni) (NESP), and Le Conte’s sparrows (Ammodramus leconteii) (LCSP) are poorly known, so systematic surveys of these elusive species are needed to inform conservation planning and guide management. A standardized protocol for monitoring secretive marsh birds exists (Conway 2009, 2011); however, these species call at night and may be missed during early-morning marsh bird surveys. I tested the effectiveness of autonomous recording units (ARUs) to survey these species by analyzing recorded vocalizations using bioacoustics software. I deployed 22 ARUs at 54 sites in northern Minnesota and …

Heavy Metals In Traditionally Used Fruits Among The Lakota, Joanita M. Kant

Electronic Theses and Dissertations

Heavy metals concentrations in soils and plants on and near Pine Ridge Reservation (PRR), SD, are a cause of concern to Oglala Lakota tribal government, particularly because of current and past uranium mining nearby, as well as familiarity with occasional selenium poisoning in livestock. In this study, concentrations of As, Ba, Pb, Se, and U were determined using ICP-OES for selected traditionally edible berries and small fruits, and the soils in which they grow. Results indicated that the heavy metals are likely of natural origin, and ingestion of these culturally important fruits at levels reported in interviews among the Lakota …

Sagebrush Ecosystem Characterization, Monitoring, And Forecasting With Remote Sensing: Quantifying Future Climate And Wildlife Habitat Change, Collin G. Homer

Electronic Theses and Dissertations

Sagebrush (Artemisia spp.) ecosystems constitute the largest single North American shrub ecosystem and provide vital ecological, hydrological, biological, agricultural, and recreational ecosystem services. Disturbances continue to alter this ecosystem, with climate change possibly representing the greatest future disturbance risk. Improved ways to characterize and monitor gradual change in this ecosystem are vital to its future management. A new remote sensing sagebrush characterization approach was developed in Wyoming which integrates three scales of remote sensing to derive four primary continuous field components (bare ground, herbaceousness, litter, and shrub), and four secondary components (sagebrush, big sagebrush, Wyoming sagebrush, and shrub …

Impacts Of Land Cover Changes On Ecosystem Services Delivery In The Black Hills Ecoregion From 1950 To 2010, Suzanne Cotillon

Electronic Theses and Dissertations

Environmental degradation generated by land use choices and human activities is the first driver of change in the provision of ecosystem goods and services. One of the challenges in ecosystem services research is to evaluate the contribution of each land cover unit to ecosystem services delivery while considering multiple services. In this thesis, I develop a framework to assess the capacity of many land covers to independently produce ecosystem services (i.e., potential production) and the capacity of the whole landscape to deliver multiple services to the population (i.e., potential supply). In the first part, this methodology is used to report …

Impacts Of Spring-Interseeded Cover Crops On Late-Emerging Weed Suppression And Ground Cover In Corn (Zea Mays L.) Production Systems, Alex D. Bich

Electronic Theses and Dissertations

Any alternative crop management strategy will only be adopted by growers if yield is not negatively impacted, fits within a current management practice, is easily implementable with minimal cost, or provides other beneficial features such as weed control or suppression. Corn production that incorporates a cover crop as an alternative weed control strategy and ground cover may support a sustainable system that is less dependent on herbicidal weed control. In addition, the cover crop may be used as a fall forage, act as a slow release fertilizer source the following year, and provide ground cover to reduce soil erosion. In …

Cultural Fit Wanted: A Content Analysis Of Human Resource Generalist Job Advertisements, Kelli J. Chromey

Electronic Theses and Dissertations

This content analytic study explored organizational anticipatory socialization through job advertisements. Human Resource (HR) Generalist positions (n = 100) listed on the Society of Human Resource Management (SHRM) website between November 6, 2012, and January 28, 2013 were analyzed through seven quantitative categories (organizational goals, HR job descriptions, job skills and abilities, communication skills, website, mission/values, and word count/reading level). Results indicated that these listings generally included information such as company name and location, but rarely revealed organizational goals, missions and values. The addition or absence of a website, along with readability and word count were also included. Implications included …

The Key Role Of Micromorphology In Studies Of The Genesis Of Clay Minerals And Their Associations In Soils And Its Relevance To Advances In The Philosophy Of Soil Science, Gordon Jock Churchman

Turkish Journal of Earth Sciences

Micromorphological observations from 3 different published works have been studied to aid understanding of aggregation and of colloids, both unique to soils. Saprolites in Hong Kong included ‘veins’ of different thicknesses and colours. Optical mineralogy identified them as infill from the neogenesis of clays in rock fractures. The common thicker infills resulted from weathering. Dark infill contained comminuted primary minerals whereas thin pale infill originated hydrothermally. Scanning electron microscopy (SEM) showed that the size, shape, and mineralogy of the kaolin minerals formed in infill depended on the types of cracks in the saprolites and on drying. Energy-dispersive X-ray spectroscopy analyses …

Inheriting Your Wind: Lawrence And Lee’S Lessons In Avoiding Servitude To The “Wise”, Lauren Lee

Understanding by Design: Complete Collection

This unit primarily seeks to explore the theme of Lawrence and Lee’s play Inherit the Wind, which Lawrence defined as “the dignity of the individual mind, and that mind’s lifelong battle against limitation and censorship”. The authors based their text around the Scopes Monkey Trial in 1925, but ambiguity in date and location suggest this play is, moreover, an allegory of events which subvert truth in favor of belief. In so exploring Lawrence and Lee’s theme, this unit connects a driven high school freshmen to contemporary and historical happenings that suppress fact and overvalue opinion, regardless of whether such beliefs …

Why Is It There: Placing Companies In The United States And Canada [9th Grade], Luaren Heath

Understanding by Design: Complete Collection

This unit is designed to discuss the regions of the United States and Canada from a more economic, rather than historical, point of view. The students must understand that the physical and human geography of a region affects the people and the economic activities. In order to achieve this, students will first look at the physical and human characteristics of the United States and Canada. This will include an investigation of the climate, landforms, other demographic information, migration patterns, and where people live. Then, using this information along with available maps the students will determine the best location for a …

Beyond Virtual Replicas: 3d Modeling And Maltese Prehistoric Architecture, Filippo Stanco, Davide Tanasi

History Faculty Publications

In the past decade, computer graphics have become strategic for the development of projects aimed at the interpretation of archaeological evidence and the dissemination of scientific results to the public. Among all the solutions available, the use of 3D models is particularly relevant for the reconstruction of poorly preserved sites and monuments destroyed by natural causes or human actions. These digital replicas are, at the same time, a virtual environment that can be used as a tool for the interpretative hypotheses of archaeologists and as an effective medium for a visual description of the cultural heritage. In this paper, the …

Forcings, Lee Anne Fennell

Coase-Sandor Institute for Law & Economics Research Paper Series

Eminent domain receives enormous amounts of scholarly and popular attention, and for good reason—it is a powerful form of government coercion that cuts to the heart of ownership. But a mirror-image form of government coercion has been almost entirely ignored: forced ownership, or "forcings." While legal compulsion to begin or continue ownership is neither entirely unstudied as an academic matter nor entirely unprecedented as a doctrinal matter, the category lacks a unified treatment. Because coercively imposed ownership can substitute for other forms of government coercion, forcings deserve attention, even if they will rarely dominate other alternatives. Attending to forcings as …
