The Lives, Lore, And Literature Of Cranes: A Catechism For Crane Lovers, Paul A. Johnsgard, Thomas D. Mangelsen

Zea E-Books Collection

This book provides basic information on cranes that should be of interest and importance to crane-loving birders (“craniacs”) as well as to ornithologists and wildlife managers. Primary consideration is given to the sandhill and whooping cranes, but all 13 of the Old World cranes are also discussed. Special consideration is given to the relative abundance and conservation status of all of the world’s species, of which nearly half are declining and a few are in real danger of long-term survival. More than 80 refuges and preserves in the United States and Canada, where the best chances of seeing cranes in …

Effects Of Freshwater Crayfish On Influenza A Virus Persistence In Water, J. Jeffrey Root, Jeremy W. Ellis, Susan A. Shriner

United States Department of Agriculture Wildlife Services: Staff Publications

Several investigations have recently assessed the ability of some aquatic invertebrates to act as tools for avian influenza A virus (IAV) surveillance as well as their potential role(s) in IAV ecology. Because of this, as well as the high IAV seroprevalence rates noted in select mesocarnivores that commonly inhabit aquatic and semi-aquatic habitats, we evaluated the effects that freshwater crayfish have on IAV in water at three dose levels and monitored for the presence of IAV in crayfish tissues (gill and green gland) and haemolymph at multiple time points. At relatively high, medium 432 and low (approximately 10 , 10 …

Tradiciones Plásticas Y Ontologías: Problemas En Torno Al Estudio De La Iconografía Del Período Medio Del No. Argentino, María Alba Bovisio

Congreso internacional sobre iconografía precolombina, Barcelona, 2019. Actas.

En este trabajo se analizan piezas producidas entre los siglos VII-XI, en el valle de Hualfín (Catamarca, Argentina) con fines cúlticos y ceremoniales, que presentan una iconografía de notable complejidad. Al respecto se propone indagar: el posible significado de las imágenes metafóricas y metonímicas que articulan humanos, felinos, saurios y reptiles, en relación al poder sagrado (lo waka) y, el rol que juega cada “tradición plástica” (escultores, grabadores, pintores) en la materialización, a través de los objetos e imágenes, del orden ontológico y cosmológico vigente en las comunidades del noroeste argentino en época prehispánica.

Jay F. Storz Publications

Environmental limits of animal life are invariably revised when the animals themselves are investigated in their natural habitats. Here we report results of a scientific mountaineering expedition to survey the high-altitude rodent fauna of Volcán Llullaillaco in the Puna de Atacama of northern Chile, an effort motivated by video documentation of mice (genus Phyllotis) at a record altitude of 6,205m. Among numerous trapping records at altitudes of >5,000 m, we captured a specimen of the yellow-rumped leaf-eared mouse (Phyllotis xanthopygus rupestris) on the very summit of Llullaillaco at 6,739 m. This summit specimen represents an altitudinal world …

An Applied Ecology Of Fear Framework: Linking Theory To Conservation Practice, Kaitlyn M. Gaynor, Michael J. Cherry, Sophie L. Gilbert, Michael T. Kohl, Courtney L. Larson, Thomas M. Newsome, Laura R. Prugh, Justin P. Suraci, Julie K. Young, Justine A. Smith

United States Department of Agriculture Wildlife Services: Staff Publications

Research on the ecology of fear has highlighted the importance of perceived risk from predators and humans in shaping animal behavior and physiology, with potential demographic and ecosystem-wide consequences. Despite recent conceptual advances and potential management implications of the ecology of fear, theory and conservation practices have rarely been linked. Many challenges in animal conservation may be alleviated by actively harnessing or compensating for risk perception and risk avoidance behavior in wild animal populations. Integration of the ecology of fear into conservation and management practice can contribute to the recovery of threatened populations, human–wildlife conflict mitigation, invasive species management, maintenance …

Agricultural Nuisance Liability In Nebraska After Lb 227 (2019), Anthony B. Schutz

Nebraska Law Bulletin (Selected Issues)

In the 2019 legislative session, the Nebraska Legislature considered LB 227. Driven in part by a concern for large verdicts awarded in cases in North Carolina and a need to expand producer protections to accommodate agricultural growth, it adopted modest changes to the statutory nuisance protection for agricultural producers. That statutory protection is often referred to as a “right-to-farm law.”

Nebraska first started wrestling with the issue of protecting producers from nuisance suits in 1977, with significant amendments in 1980. In 1982, Nebraska adopted new statutes that largely displaced those earlier efforts. Those 1982 statutes, Neb. Rev. Stat. sections 2-4401 …

Low grade, chronic inflammation is a critical risk factor for immunologic dysfunction including autoimmune diseases. However, the multiplicity of complex mechanisms and lack of relevant murine models limit our understanding of the precise role of chronic inflammation. To address these hurdles, we took advantage of multi-omics data and a unique murine model with a low but chronic expression of IFN-γ, generated by replacement of the AU-rich element (ARE) in the 3’ UTR region of IFN-γ mRNA with random nucleotides. Herein, we demonstrate that low but differential expression of IFN-γ in mice by homozygous or heterozygous ARE replacement triggers distinctive gut …

Epstein Barr Virus-Immortalizedｂlymphocytes Exacerbate Experimental Autoimmune Encephalomyelitis In Xenograft Mice, Pascal Polepole, Alison Bartenslager, Yutong Liu, Thomas M. Petro, Samodha C. Fernando, Luwen Zhang

Nebraska Center for Virology: Faculty Publications

Multiple sclerosis (MS) is the most common autoimmune disorder affecting the central nervous system. Epstein-Barr virus (EBV) is a causative agent for infectious mononucleosis (IM) that is associated with MS pathogenesis. However, the exact mechanism by which EBV, specifically in IM, increases the risk for MS remains unknown. EBV immortalizes primary B lymphocytes in vitro and causes excessive B lymphocyte proliferation in IM in vivo. In asymptomatic carriers, EBV-infected B lymphocytes still proliferate to certain degrees, the process of which is tightly controlled by the host immune systems. Experimental autoimmune encephalomyelitis (EAE) mimics key features of MS in humans …

Evaluating Opportunities For Integrated Crop Livestock Systems In Eastern Nebraska, Elizabeth Kay Christenson

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Current agricultural systems focused on production of few commodities are facing production, economic, and environmental challenges. To address these challenges, Integrated Crop Livestock Systems (ICLS) have emerged through three primary methods 1) perennial grasslands for grazing and/or hay production, 2) crop residue grazing, and 3) cover crop grazing. To evaluate potential of ICLS mitigating current challenges, a field scale model ICLS was developed in 2015. The ICLS includes 4-ha each of ‘Newell’ smooth bromegrass (Bromus inermis L.), ‘Liberty’ switchgrass (Panicum virgatum L.), and ‘Shawnee’ switchgrass. The ICLS also included 8-ha of continuous corn (Zea mays L.). In …

Understanding The Impact Of Room Acoustic Conditions On The Kurtosis Levels Of Various Noise Signals, William Spallino

Durham School of Architectural Engineering and Construction: Dissertations, Theses, and Student Research

Impulsive noise can be common in certain occupational and recreational settings, such as manufacturing plants, construction sites, and firing ranges. While many regulations and guidelines for noise exposure exist, their mathematical basis is stronger for continuous noise, and concerns have been raised about the possibility that impulsive noise may be more harmful to people’s hearing than those metrics would let on. Much work has been done on establishing metrics that accurately assess the severity and hearing risk associated with impulsive noise, but the effects of room acoustic conditions on those metrics have been heretofore understudied.

This study calculated room impulse …

Metabolic Benefits Of Plant-Based N-3 Polyunsaturated Fatty Acids On Brown Thermogenesis, Kyung Ho Park

Department of Nutrition and Health Sciences: Dissertations, Theses, and Student Research

There are two essential fatty acids for humans, a-linolenic acid (ALA) and linoleic acid (LA), which should be taken from foods to maintain health. Once incorporated into cells, ALA and LA, which are omega-3 poly unsaturated fatty acid (n-3 PUFA) and n-6 PUFA respectively, undergo elongation and desaturation to generate longer and more unsaturated fatty acids influencing inflammation and immunological responses. Numerous studies showed a dietary reduction of n-6/n-3 PUFA ratio improves cardiovascular health, inflammation, and insulin resistance. Fish oil, the main resource for n-3 PUFA, is shown to increase these health benefits. In our lab, we investigated the efficacy …

Frontal Vehicle Illumination Via Rear-Facing Lighting Reduces Potential For Collisions With White-Tailed Deer, Travis L. Devault, Thomas W. Seamans, Bradley Blackwell

United States Department of Agriculture Wildlife Services: Staff Publications

nimal–vehicle collisions cause many millions of animal deaths each year worldwide and present a substantial safety risk to people. In the United States and Canada, deer (Odocoileus spp.) are involved in most animal–vehicle collisions associated with human injuries. We evaluated a vehicle-based collision mitigation method designed to decrease the likelihood of deer–vehicle collisions during low-light conditions, when most collisions occur. Specifically, we investigated whether the use of a rear-facing light, providing more complete frontal vehicle illumination than standard headlights alone, enhanced vehicle avoidance behaviors of white-tailed deer (O. virginianus). We quantified flight initiation distance (FID), the likelihood …

A Survey Of Dairy-Goat Keeping In Zanzibar, Tiffanie Stone, Charles A. Francis, L. O. Eik

Department of Agronomy and Horticulture: Faculty Publications

Dairy goats with improved genetics for milk production were recently introduced onto small-scale farms in Zanzibar through governmental and non-governmental projects. These projects were meant to support small-scale farmers by improving both income and household nutrition through milk production. No follow up had been conducted to understand what effects dairy goat keeping had on these small-scale farms, or how they could be improved. A survey of 193 dairy goat farmers in Zanzibar was conducted, including 30% and 60% of all dairy goat farmers on Unguja and Pemba, the two largest islands, respectively. The objective was to understand the impact keeping …

Effects Of Ndf Digestibility On Lactating Jersey Cows: Observed And Modeled Performance, Kirby Craig Krogstad

Department of Animal Science: Dissertations, Theses, and Student Research

Improving the digestibility of fiber and our understanding of how to feed it will optimize the ruminants’ niche in our society, which is to convert human inedible products to high quality protein in the form of meat and milk. Neutral detergent fiber (NDF) digestibility has been studied and modeled for decades, but it is increasingly important as livestock production is scrutinized for resource use and sustainability. Increasing the amount of NDF fed and improving models of NDF digestibility will improve sustainability by increasing the precision at which we feed livestock which results in less nutrient and greenhouse gas (GHG) emissions. …

The Role Of Postnatal Adrenergic Manipulation In The Mediation Of Fetal Programming Adaptions In Growth And Skeletal Muscle Glucose Metabolism That Persist In The Juvenile Iugr-Born Lamb, Rachel L. Gibbs

Department of Animal Science: Dissertations, Theses, and Student Research

Our 1^st study assessed growth deficits in IUGR juvenile lambs and the benefits of treatment with adrenergic and inflammatory mediators. Growth metrics including bodyweight, rate of gain, and crown-rump length were diminished by placental insufficiency-induced IUGR through 2 mo. of age but were recovered by daily clenbuterol or curcumin supplementation. Body composition metrics indicated by bioelectrical impedance, proximate analysis, and loin size revealed that fat-free lean mass, specific muscle group sizes, and protein-to-fat ratios were reduced in unsupplemented IUGR lambs but recovered to or even past controls in clenbuterol-supplemented lambs. From these findings, we conclude that IUGR impairs postnatal …
