Effects Of The Wetlands Reserve Program On Waterfowl Carrying Capacity In The Rainwater Basin Region Of South-Central Nebraska, Andy A. Bishop, Mark P. Vrtiska

Nebraska Game and Parks Commission: Staff Research Publications

The purpose of this Conservation Effects Assessment Project (CEAP) assessment was to evaluate the energetic contribution of the Wetlands Reserve Program (WRP) for migratory waterfowl using the Rainwater Basin Wetland Complex (RWB). The RWB is located in south central Nebraska and encompasses 6,150 mi2 that is dominated by row crop agriculture. Historically, > 204,000 acres of playa wetlands were scattered across this region, but currently, just over 40,000 acres of wetlands remain. Annually, an estimated 12.4 million migratory waterfowl use this region during fall and/or spring migrations. Although used with less intensity as a fall stopover, approximately 9.8 million birds use …

Urban Essentials, Ruthie G. Gould

Architecture Masters of Science Program: Theses

Industrial development throughout the world has led to a global society. Although sharing of information and technology is beneficial in many ways, these global means have also created many issues that are not always contributing to economic and social societies. International business is not only unsustainable for environmental reasons, but it also often means that many unethical decisions are made for the purposes of cheap labor, mass revenue, and other un-amiable intentions. The Urban Essentials project’s purpose is to create an urban area that searches for a solution against these capitalistic means of business. This idea is realized in the …

Analysis Of Gnrh Receptor Gene Expression On Lines Of Swine With Divergent Ovulation Rates, Jacqueline E. Smith

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

To examine the relationship between the molecular mechanisms underlying ovulation rate and transcriptional regulation of the porcine GnRHR gene, our laboratory has isolated the GnRHR gene promoter from the Control, Index and Meishan lines (McDonald, 2005). Previous work in our laboratory has indicated divergent luciferase activity among reporter vectors containing 5000 bp of 5’ flanking region for the porcine GnRHR gene from all three genetic lines transiently transfected into gonadotrope-derived αT3-1 cells (Fig 1.1; McDonald, 2005). This suggests differential mechanisms involved in the transcriptional regulation of the GnRHR gene among pig strains. Additionally, our laboratory identified a single base alteration …

Leaf Area Index Simulation In Soybean Grown Under Near-Optimal Conditions, T. D. Setiyono, Albert Weiss, James E. Specht, Kenneth G. Cassman, A. Dobermann

Department of Agronomy and Horticulture: Faculty Publications

Different approaches have been used to simulate leaf area index (LAI) in soybean (Glycine max L. Merr). Many of these approaches require genotype-specific calibration procedures. Studies modeling LAI dynamics under optimal growth conditions with yields close to the yield potential of soybean have remained scarce. A sink-driven approach was developed and evaluated for LAI simulation in soybean under near-optimal environments. The rate of change in expanding leaf area was simulated using the first derivative of a logistic function accounting for plant population density, air temperature, and water deficit. The rate of change in senescing leaf area was also simulated …

Artificial Neural Network Estimation Of Soil Erosion And Nutrient Concentrations In Runoff From Land Application Areas, Minyoung Kim, John E. Gilley

Department of Agricultural and Biological Systems Engineering: Faculty Publications

The transport of sediment and nutrients from land application areas is an environmental concern. New methods are needed for estimating soil and nutrient concentrations of runoff from cropland areas on which manure is applied. Artificial Neural Networks (ANNs) trained with a backpropagation (BP) algorithm were used to estimate soil erosion, dissolved P (DP) and NH₄–N concentrations of runoff from a land application site near Lincoln, Nebraska, USA. Simulation results from ANN-derived models showed that the amount of soil eroded is positively correlated with rainfall and runoff. In addition, concentrations of DP and NH₄–N in overland flow …

Elk Calf Survival And Mortality Following Wolf Restoration To Yellowstone National Park, Shannon M. Barber-Meyer, L. David Mech, P. J. White

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

We conducted a 3-year study (May 2003–Apr 2006) of mortality of northern Yellowstone elk (Cervus elaphus) calves to determine the cause for the recruitment decline (i.e., 33 calves to 13 calves/100 adult F) following the restoration of wolves (Canis lupus). We captured, fit with radiotransmitters, and evaluated blood characteristics and disease antibody seroprevalence in 151 calves ≤6 days old (68M:83F). Concentrations (x, SE) of potential condition indicators were as follows: thyroxine (T4; 13.8 μg/dL, 0.43), serum urea nitrogen (SUN; 17.4 mg/dL, 0.57), γ-glutamyltransferase (GGT; 66.4 IU/L, 4.36), gamma globulins (GG; 1.5 g/dL, 0.07), and insulin-like growth …

Gnrh Immunocontraception Of Male And Female White-Tailed Deer Fawns, Lowell A. Miller, James P. Gionfriddo, Jack C. Rhyan, Kathleen A. Fagerstone, Donald C. Wagner, Gary J. Killian

United States Department of Agriculture Wildlife Services: Staff Publications

Immunocontraceptive vaccines based on gonadotropin-releasing hormone (GnRH) have been tested in adult white-tailed deer (Odocoileus virginianus), but their effects on fawns are unknown. The purpose of this study was to determine if early immunization against GnRH would induce a long-lasting immune response in fawns, and if it would delay or prevent sexual development. We gave primary and subsequent booster injections of a KLH-GnRH/Freund’s vaccine to 6 male and 6 female fawns. This vaccine contained the same active ingredients as GonaCon™ vaccine, but it contained Freund’s adjuvant instead of AdjuVac™ adjuvant. Two 450-μg injections were given 1 month apart …

Nitrogen Uptake, Fixation And Response To Fertilizer N In Soybeans: A Review, F. Salvagiotti, Kenneth G. Cassman, James E. Specht, Daniel T. Walters, Albert Weiss, Achim R. Dobermann

Department of Agronomy and Horticulture: Faculty Publications

Although relationships among soybean (Glycine max [L.] Merr) seed yield, nitrogen (N) uptake, biological N₂ fixation (BNF), and response to N fertilization have received considerable coverage in the scientific literature, a comprehensive summary and interpretation of these interactions with specific emphasis on high yield environments is lacking. Six hundred and thirty-seven data sets (site–year–treatment combinations) were analyzed from field studies that had examined these variables and had been published in refereed journals from 1966 to 2006. A mean linear increase of 0.013 Mg soybean seed yield per kg increase in N accumulation in above-ground biomass was evident in …

An Investigation Of Techniques For Using Oxalic Acid To Reduce Varroa Mite Populations In Honey Bee Colonies And Package Bees, Nicholas Aliano

Department of Entomology: Dissertations, Theses, and Student Research

I investigated strategies for reducing Varroa mite populations (Varroa destructor) in honey bee colonies (Apis mellifera) using oxalic acid (OA). I examined the efficacy of OA in both broodless colonies and colonies that contain brood. My data indicate that OA is most effective at reducing Varroa populations when colonies are broodless because repeated applications of OA did not significantly reduce mite populations in colonies when brood was present. Next, I quantified the contact toxicity of OA to Varroa mites and their honey bee hosts in laboratory bioassays. The results indicate that OA has a low acute …

Implementing Mass Nutrient Balance Procedures On Swine Production Facilities, Richard Koelsch, Alan Sutton

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Whole Farm Nutrient Balance (WFNB) approaches have been used to provide a measure of environmental performance (Aarts et al., 1992; Lanyon and Beegle, 1993; Klausner, 1995). Whole farm balance concepts are used as part of the Netherlands Mineral Accounting System public policy that includes compulsory mineral input and output reports from livestock farms and levies for excess imbalances (Jongbloed and Lenis, 1998). Procedures for measuring WFNB will be followed in measurements made on commercial swine facilities for 2006 and 2007. The conclusions developed based upon data from 13 for 2006 include:

• On average, the participating swine producers import 1.5 units …

Molybdoproteomes And Evolution Of Molybdenum Utilization, Yan Zhang, Vadim N. Gladyshev

Vadim Gladyshev Publications

The trace element molybdenum (Mo) is utilized in many life forms, where it is a key component of several enzymes involved in nitrogen, sulfur, and carbon metabolism. With the exception of nitrogenase, Mo is bound in proteins to a pterin, thus forming the molybdenum cofactor (Moco) at the catalytic sites of molybdoenzymes. Although a number of molybdoenzymes are well characterized structurally and functionally, evolutionary analyses of Mo utilization are limited. Here, we carried out comparative genomic and phylogenetic analyses to examine occurrence and evolution of Mo utilization in bacteria, archaea, and eukaryotes at the level of (i) Mo transport and …

Extending The Security Net The Impact Of Rangeland Insurance On Ranching Economy And Culture, Rex J. Rowley

Great Plains Quarterly (through 2013)

Humans have a complex relationship with the land. At the base of it lies our need for what the land can give: materials for shelter, food and water for sustenance, and scenic beauty for pleasure. But, similar to our interactions with other humans, our relationship with the land is not always perfect. The land can often be our worst enemy. Storm, drought, famine, and pestilence are common words from the historical record representing times when this connection between humans and nature is challenged.

Crop insurance is a relatively recent invention that attempts to level the playing field in our contest …

Porcine Reproductive And Respiratory Syndrome Virus Infects Mature Porcine Dendritic Cells And Up-Regulates Interleukin-10 Production, Lilian Flores-Mendoza, Erika Silva-Campa, Monica Resendiz, Fernando A. Osorio, Jesus Hernandez

Nebraska Center for Virology: Faculty Publications

Porcine reproductive and respiratory syndrome virus (PRRSV) infects mature dendritic cells (mDCs) derived from porcine monocytes and matured with lipopolysaccharide. The infection of mDCs induced apoptosis, reduced the expression of CD80/86 and major histocompatibility complex class II molecules, and increased the expression of interleukin-10, thus suggesting that such mDC modulation results in the impairment of T-cell activation.

Spatial Distribution Of Transcript Changes In The Maize Primary Root Elongation Zone At Low Water Potential, William G. Spollen, Wenjing Tao, Babu Valliyodan, Kegui Chen, Lindsey G. Hejlek, Jong-Joo Kim, Mary E. Lenoble, Jinming Zhu, Hans J. Bohnert, David Henderson, Daniel P. Schachtman, Georgia E. Davis, Gordon K. Springer, Robert E. Sharp, Henry T. Nguyen

Department of Agronomy and Horticulture: Faculty Publications

Background: Previous work showed that the maize primary root adapts to low Ψ_w (-1.6 MPa) by maintaining longitudinal expansion in the apical 3 mm (region 1), whereas in the adjacent 4 mm (region 2) longitudinal expansion reaches a maximum in well-watered roots but is progressively inhibited at low Ψ_w. To identify mechanisms that determine these responses to low Ψ_w, transcript expression was profiled in these regions of water-stressed and well-watered roots. In addition, comparison between region 2 of water-stressed roots and the zone of growth deceleration in well-watered roots (region 3) distinguished stress-responsive genes …

Miniature Cattle: For Real, For Pets, For Production, Dana W. R. Boden

University of Nebraska-Lincoln Libraries: Faculty Publications

Recent years have seen more and more interest in small, hobby farms, as well as retirees moving to acreages. The growing group of small landowners and producers is driving a move supporting production of smaller cattle. Miniature cattle are perfect for these settings. These cattle are located in all fifty U.S. states, as well as around the world. This article addresses: reasons for the recent, growing interest in miniature cattle; how their miniature status is defined; the major players involved in the breeding, development and promotion of these cattle; the populations miniature cattle are most attractive to; the breeds being …
