Corn Stalk Nitrate Concentration Profile: Implications For The End-Of-Season Stalk Nitrate Test, Wally Wilhelm, Gary E. Varvel, James S. Schepers

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The end-of-season corn (Zea maysL.) stalk nitrate-N test was developed as a post-mortem to determine if excessive or insufficient N was available to the corn crop during the latter part of the season. The stalk section specified for the test was very specific, the 20 cm-long section between 15 and 35 cm above the soil. Under production conditions, it may not always be possible to collect this precise stalk section. The objective of this study was to determine how nitrate concentration varied within the stalk from the soil level to the ear node, and how this variation could …

Attracting Consumers With Locally Grown Products, Food Processing Center

Food Processing Center: Reports

This report summarizes the initial findings of a survey of 500 households in the states of Nebraska, Iowa, Missouri and Wisconsin. The primary grocery shopper in the household was surveyed for their attitudes and opinions on locally grown and produced food, organic and all-natural food and meat purchasing behaviors.

To access a respondent’s purchasing behavior, each respondent was asked to rank the importance of twelve attributes in determining the product or brand they purchase. The attributes most important to consumers in the region* include taste, quality, nutrition/healthfulness, and price. Seven in ten respondents said that it was very or extremely …

Winter Severity And Wolf Predation On A Formerly Wolf-Free Elk Herd, L. David Mech, Douglas W. Smith, Kerry M. Murphy, Daniel R. Macnulty

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

We studied wolf (Canis lupus) predation on elk (Cervus elaphus) in Yellowstone National Park from 17 March to 15 April 1997 (severe winter conditions) and from 2 to 31 March 1998 (mild winter conditions) 2-3 years after wolves were reintroduced to the park. Elk composed 91% of 117 kills. Data comparisons for 1997 versus 1998 were: hunting success rate, 26% versus 15%; kill rate, 17.1 kg/wolf/day versus 6.1; percent of kill consumed in first day, 7 versus 86; percent femur marrow fat of adult kills, 27 versus 70; calf:adult ratios of kills, 2:33 versus 17:23; sex …

Porcine Zona Pellucida Immunocontraception: Long-Term Health Effects On White-Tailed Deer, Lowell A. Miller, Ken Crane, Stan Gaddis, Gary J. Killian

United States Department of Agriculture Wildlife Services: Staff Publications

As part of a 9-year study on the contraceptive effects of Porcine Zona Pellucida (PZP) on white-tailed deer (Odocoileus virginianus), we analyzed serum chemistry panels during the first 4 years. This included the first 2 years when does were being actively immunized, and 2 years post-immunization. The chemistry panel was designed to detect pathologies that might result from the immunization of the deer. Blood chemistry results did not suggest any pathological changes resulting from the immunization. Seasonal differences in serum cholesterol were similar in both the control and PZP-treated groups. Seasonal changes in the mean body weights of …

Lnduced Resistance To Bean Leaf Beetle (Coleoptera: Chrysomelidae) In Soybean, P. Srinivas, Stephen D. Danielson, C. Michael Smith, John E. Foster

Department of Entomology: Faculty Publications

Induced resistance in soybean, Glycine max (L.) Merrill, to the bean leaf beetle, Cerotoma trifurcata (Forster), was investigated in greenhouse experiments using the treatments of mechanical injury, a chemical inducer (ActigardrM, Novartis Crop Protection lnc., Greensboro, NC) and defoliation by the bean leaf beetle and the soybean looper, Pseudoplusia includens (Walker). Experiments were conducted on soybean Pl 227687, two soybean cultivars (Colfax and Williams 82) and a soybean germplasm line (HC95-24MB). Dual-choice feeding-preference tests with bean leaf beetle adults were used to assess induced resistance. Adult beetles were collected from soybean fields 2 to 5 d prior to the feeding …

Epimerite-Host Epithelium Relationships Among Eugregarines Parasitizing The Damselflies Enallagma Civile And Ischnura Verticalis, Tamara J. Percival Cook, John J. Janovy Jr., Richard E. Clopton

John J. Janovy, Jr. Publications

The host-parasite interface between two species of damselflies and four species of eugregarines was examined at the ultrastructural level. Nubenocephalus nebraskensis organisms attached to the host midgut epithelium by means of a sucker-like protomerite; the space between the epicytic folds and host epithelium was filled with electron-dense material interpreted to be adhesive in nature. Actinocephalus carrilynnae organisms attached by means of the epimerite, which had no epicytic folds, and by the fluted stalk with characteristic epicytic folds; host cell and parasite membranes appeared fused at some places on the epimerite. Hoplorhynchus acanthatholius organisms attached by means of an ovoid epimerite …

The Role Of Predation In Wildlife Population Dynamics, Eric M. Gese, Frederick F. Knowlton

United States Department of Agriculture Wildlife Services: Staff Publications

The role predation plays in the dynamics of prey populations is controversial. Our understandings of predator-prey relationships is complicated by a multitude of factors in the environment and a general lack of knowledge of most ecological systems. Various other factors, besides predation, may regulate or limit prey populations, and various factors influence the degree to which predation affects prey populations. Furthermore, some factors may create time lags, or even cause generational effects, that go unnoticed. Herein, we review the role of predation in wildlife population dynamics, some of the factors influencing predator-prey interactions, and attempt to indicate where the professional …

The Metabolic Basis Of Life History Variation: Genetic And Phenotypic Differences In Lipid Reserves Among Life History Morphs Of The Wing-Polymorphic Cricket, Gryllus Firmus, Anthony J. Zera, A. Larsen

Anthony Zera Publications

The flight-capable morph of the wing-polymorphic cricket, Gryllus firmus, accumulated a substantially greater quantity of total lipid and triglyceride, compared with the obligately flightless morph, during the first five days of adulthood. Increased lipid accumulation in the flight-capable morph was genetically based, and was produced when ovarian growth is substantially reduced in that morph. Temporal changes in lipid levels suggest that the higher triglyceride reserves in the flight-capable morph fed a high-nutrient diet were produced by elevated lipid biosynthesis. By contrast, on a low-nutrient or high carbohydrate diet, increased lipid levels in the flight-capable morph appeared to result primarily …

Book Review: Grazing Management, 2nd Ed., Lowell E. Moser

Department of Agronomy and Horticulture: Faculty Publications

Grazing management is critical in obtaining optimum production from grasslands and maintaining the grazing resource. Grazing management involves a complex relationship among the herbivores, vegetation, and other biotic and abiotic factors. Proper grazing management of grazing lands has a tremendous importance in agriculture and natural resource conservation because much of the earth’s surface is covered with grazable vegetation. This book is an updated second edition of Grazing Management, which was first published in 1990. This edition is increased in size and coverage compared with the first edition.. A lot of progress in grazing management has been made in the 11 …

Farm Bill Moves To Fast Track, Roy Frederick

Cornhusker Economics

Time to fish or cut bait with respect to a new farm bill. Six months ago, I would have bet on bait-cutting. Now, I’m not so sure. We just might go fishing before the year is over.

History is on the side of tardy completion of farm bills. In 1985 and 1990, bills were signed into law just days before the December 31 expiration of the old legislation. Then, in 1995, deliberations lagged even more. That year’s farm bill was not completed until April, 1996. (Subsequently, it has come to be known as the 1996--not the 1995--farm bill).

Current legislation …

Mycobacterium Avium Subsp. Paratuberculosis In Veterinary Medicine, N. Beth Harris, Raul G. Barletta

School of Veterinary and Biomedical Sciences: Faculty Publications

Bacteria of the genus Mycobacterium are gram-positive, acid- fast organisms that include a number of significant human and animal pathogens. Mycobacterium avium subsp. paratuberculosis (basonym M. paratuberculosis) is the etiological agent of a severe gastroenteritis in ruminants, known as Johne’s disease. H. A. Johne and L. Frothingham initially reported the disease in Germany in 1894. However, it was not until 1910 that F. W. Trowt successfully fulfilled Koch’s postulates by growing M. paratuberculosis in the laboratory and reproducing the disease in experimentally infected cattle (46, 148). Johne’s disease is prevalent in domestic animals worldwide and has significant impact on …

Quorum Sensing In The Dimorphic Fungus Candida Albicans Is Mediated By Farnesol, Jacob M. Hornby, Ellen C. Jensen, Amber C. Lisec, Joseph J. Tasto, Brandon Jahnke, Richard Shoemaker, Patrick Dussault, Kenneth W. Nickerson

Patrick Dussault Publications

The inoculum size effect in the dimorphic fungus Candida albicans results from production of an extracellular quorum-sensing molecule (QSM). This molecule prevents mycelial development in both a growth morphology assay and a differentiation assay using three chemically distinct triggers for germ tube formation (GTF): L-proline, N-acetylglucosamine, and serum (either pig or fetal bovine). In all cases, the presence of QSM prevents the yeast-to-mycelium conversion, resulting in actively budding yeasts without influencing cellular growth rates. QSM exhibits general cross-reactivity within C. albicans in that supernatants from strain A72 are active on five other strains of C. albicans and vice versa. …

Germplasm Evaluation Program- Progress Report No. 21, Larry V. Cundiff, T. L. Wheeler, Keith Gregory, Steven D. Shackelford, M. Koohmaraie, R. M. Thallman, L. Dale Van Vleck

Roman L. Hruska U.S. Meat Animal Research Center: Reports

Breed differences in performance characteristics are an important genetic resource for improving efficiency of beef production. Diverse breeds are required to exploit heterosis and breed complementarity through crossbreeding and development of composite populations to match genetic potential with diverse markets, feed resources and climates. Beef producers are under increasing pressure to reduce fat while maintaining or improving tenderness and palatability of products. No single breed excels in all traits of economic importance to beef production. This report presents preliminary results from Cycle VII of the Germplasm Evaluation Program at the Roman L. Hruska U.S. Meat Animal Research Center (U.S. Meat …

Oxidative Responses Of Resistant And Susceptible Cereal Leaves To Symptomatic And Nonsymptomatic Cereal Aphid (Hemiptera: Aphididae) Feeding, Xinzhi Ni, Sharron S. Quisenberry, Tiffany Heng-Moss, John P. Markwell, Gautam Sarath, Robert Klucas, Frederick P. Baxendale

Department of Entomology: Faculty Publications

The impact of the leaf-chlorosis-eliciting Russian wheat aphid, Diuraphis noxia (Mordvilko), and the nonchlorosis-eliciting bird cherry-oat aphid, Rhopalosiphum padi (L.), feeding on D. noxia-susceptible and -resistant cereals was examined during the period (i.e., 3, 6, and 9 d after aphid infestation) that leaf chlorosis developed. After aphid number, leaf rolling and chlorosis ratings, and fresh leaf weight were recorded on each sampling date, total protein content, peroxidase, catalase, and polyphenol oxidase activities of each plant sample were determined spectrophotometrically. Although R. padi and D. noxia feeding caused significant increase of total protein content in comparison with the control cereal …

Selective Inhibition Of Selenocysteine Trna Maturation And Selenoprotein Synthesis In Transgenic Mice Expressing Isopentenyladenosine-Deficient Selenocysteine Trna, Mohamed E. Moustafa, Bradley A. Carlson, Muhammed A. El-Saadani, Gregory V. Kryukov, Qi-An Sun, John W. Harney, Kristina E. Hill, Gerald F. Combs, Lionel Feigenbaum, David B. Mansur, Raymond F. Burk, Marla J. Berry, Alan M. Diamond, Byeong Jae Lee, Vadim Gladyshev, Dolph A. Hatfield

Vadim Gladyshev Publications

Selenocysteine (Sec) tRNA (tRNA ^[Ser]Sec) serves as both the site of Sec biosynthesis and the adapter molecule for donation of this amino acid to protein. The consequences on selenoprotein biosynthesis of overexpressing either the wild type or a mutant tRNA ^[Ser]Sec lacking the modified base, isopentenyladenosine, in its anticodon loop were examined by introducing multiple copies of the corresponding tRNA ^[Ser]Sec genes into the mouse genome. Overexpression of wild-type tRNA ^[Ser]Sec did not affect selenoprotein synthesis. In contrast, the levels of numerous selenoproteins decreased in mice expressing isopentenyladenosine-deficient (i⁶A^-) tRNA ^[Ser]Sec in a protein- and …

What’S Ahead For Farm Programs?, Roy Frederick

Cornhusker Economics

At a family gathering over the long Memorial Day week-end, a shirttail relative used this for a conversation starter: “So, have you got the new farm bill figured out?” My response was a quick and unequivocal “no.” In fact, the whole process becomes more uncertain as the Democrats assume majority control of the U.S. Senate.
The House Agriculture Committee originally had planned to complete at least the commodity titles (sections) of a new farm bill by July 11, 2001. More recently, the House target date has been pushed back to August. The leadership on that panel still holds out hope …

Chapter 13. The 15 Kda Selenoprotein (Sepl5): Functional Studies And A Role In Cancer Etiology, Vadim Gladyshev, Alan M. Diamond, Dolph L. Hatfield

Vadim Gladyshev Publications

The 15 kDa selenoprotein (Sepl5) is one of several recently identified selenoproteins. It contains a single selenocysteine residue in the middle of a 162-amino acid open reading frame and has no detectable homology to known proteins. The human Sepl5 gene spans 5 1 kb, has 5 exons and is located on chromosome 1 at position p3 1. The gene contains two single nucleotide polymorphisms in the 3'-untranslated region (3'-UTR) including one in the SECIS element, that are distributed differently between Caucasians and African Americans. Sep15 localizes to the endoplasmic reticulum where it is tightly bound to UDP-glucose:glycoprotein glucosyltransferase, a protein …
