Comparative Salt And Waterlogging Tolerance Of An Introduced Grass (Agropyron Elongatum [Host] P. Beauv.) And Two Herbaceous Australian Species (Podolepis Gracilis [Lehm.] And Danthonia Caespitosa Gaud.), Bryan William Duff

Theses : Honours

Increasing land degradation is recognised as an immediate worldwide threat. Human induced soil salinity is probably the major cause of land abandonment, through its adverse effects on plant growth. Salinity is a major focus of environmental researchers because it is recognised that counter-strategies can potentially reclaim both artificially degraded lands and intrinsically saline areas. Currently, strategies to combat salinity require that land use is changed, since restoration to a past use is usually economically impractical or impossible. Biological strategies show most promise. Revegetation of degraded soils with hardy plant species has met with considerable success, and shows promise for the …

Helminths Of The Southwestern Toad, Bufo Microscaphus, Woodhouse's Toad, Bufo Woodhousii (Bufonidae), And Their Hybrids From Central Arizona, Stephen R. Goldberg, Charles R. Bursey, Keith B. Malmos, Brian K. Sullivan, Hay Cheam

Great Basin Naturalist

The gastrointestinal tracts, lungs, and urinary bladders from 77 Bufo microscaphus, 61 Bufo woodhousii, and 8 of their hybrids were examined for helminths. One species of trematode (Glypthelmins quieta), 1 species of cestode (Distoichometra bufonis), and 5 species of nematodes (Aplectana incerta, A. itzocanensis, Rhabdias americanus, Physaloptera sp., and Physocephalus sp.) were found. The greatest prevalence (41%) and mean intensity (231.7) were recorded for Aplectana incerta in Bufo woodhousii. It appears hybrids harbor fewer parasites than either parent species.

Transmittance And Reflectance Measurements Of Corn Leaves From Plants With Different Nitrogen And Water Supply, James S. Schepers, T. M. Blackmer, Wallace Wilhelm, M. Resende

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

Nitrogen is essential for crop production, but also contributes to eutrophication of surface water and degradation of drinking water quality. Modern corn production requires relatively large quantities of N, which are generally supplied by fertilizers. Over-application of N fertilizers and animal wastes frequently results in nitrate leaching. Synchronizing N availability with crop N need offers the potential to protect the environment without sacrificing production. Tools are needed to rapidly and easily monitor crop N status to make timely decisions regarding fertilizer application. Analytical and optical techniques were evaluated with greenhouse grown corn at silking to evaluate several methods to monitor …

Effect Of Sediment Particle Size And Temperature On Fecal Bacteria Mortality Rates And The Fecal Coliform/Fecal Streptococci Ratio, J. M. Howell, Mark S. Coyne, P. L. Cornelius

Plant and Soil Sciences Faculty Publications

Extended survival of fecal bacteria in sediment can obscure the source and extent of fecal contamination in agricultural settings. The variability in fecal coliform/fecal streptococci (FC/FS) ratios with time and discrepancies between observable fecal sources and measured FC/FS ratios in shallow surface water from agricultural watersheds may be explained by examining FC and FS mortality rates in response to ambient temperature and sediment particle size. We measured FC and FS mortality rates at three different temperatures and in three feces-amended sediments with different particle size in a laboratory study. In controlled conditions, using physiological saline to reduce cell death by …

Western Australian Salinity Action Plan, Agriculture Western Australia, Department Of Conservation And Land Management, Department Of Environmental Protection, Water And Rivers Commission

Natural resources published reports

Salinity is one of the State's most critical environmental problems, threatening major economic and social consequences. It is preventable and, in the long term, reversible. Complete elimination is not realistic, but we can dramatically reduce its impact.

Salinity is caused by replacing deep-rooted native plants with shallow-rooted crops and pastures. More rainfall passed below the root zone and accumulates as groundwater so that watertables rise. The groundwater mobilises natural salts in the soil as it rises and carries them towards the surface, eventually degrading land and streams.

Expression And Characterization Of An Rna Capping Enzyme Encoded By Chlorella Virus Pbcv-1, C. Kiong Ho, James L. Van Etten, Stewart Shuman

Department of Plant Pathology: Faculty Publications

We report that the A103R protein of Chlorella virus PBCV-1 is an mRNA capping enzyme that catalyzes the transfer of GMP from GTP to the 5’ diphosphate end of RNA. This is a two-step reaction in which the enzyme first condenses with GTP to form a covalent enzyme-GMP intermediate and then transfers the GMP to an RNA acceptor to form a GpppN cap. Purified recombinant A103R is a 38-kDa monomer that lacks RNA (guanine-7-) methyltransferase activity. With respect to its size, amino acid sequence, and biochemical properties, A103R is more closely related to the yeast RNA guanylyltransferases than it is …

The aims were to provide a summary of local wisdom regarding pasture …

Monoclonal Antibodies For Detection Of The H7 Antigen Of Escherichia Coli, Yongsheng He, James E. Keen, Ralph B. Westerman, E. Travis Littledike, Jimmy Kwang

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

Two murine monoclonal antibodies (MAbs) (2B7 and 46E9-9) reactive with the H7 flagellar antigen of Escherichia coli were produced and characterized. A total of 217 E. coli strains (48 O157:H7, 4 O157:NM, 23 O157:non-H7, 22 H7:non-O157, and 120 non-O157:non-H7), 17 Salmonella serovars, and 29 other gramnegative bacteria were used to evaluate the reactivities of the two MAbs by indirect enzyme-linked immunosorbent assay (ELISA). Both MAbs reacted strongly with all E. coli strains possessing the H7 antigen and with H23- and H24-positive E. coli strains. Indirect ELISA MAb specificity was confirmed by inhibition ELISA and by Western blotting (immunoblotting), using partially …

Outdoor Living Barn: A Specialized Windbreak, Kris Irwin, Jerry Bratton

Agroforestry Notes (USDA-NAC)

In April of 1987, a spring blizzard swept through northern Kansas and southern Nebraska killing nearly 60,000 newborn calves and other winter stressed animals. This tremendous loss could have been lessened had protection, such as outdoor living barns (OLB), been provided to reduce the windchill. An outdoor living barn is a specialized windbreak, typically composed of trees and shrubs, and strategically located in open grasslands, center pivot irrigation corners, and pasture areas to protect livestock during severe weather situations.

The purpose of an OLB is to: 1) defuse and deflect cold winds away from livestock, moderating the windchill; and 2) …

Forage Quality Of "Matua" Prairie Grass, Kelly King

Masters Theses & Specialist Projects

Research on the nutritive quality of Matua grass (Bromus willdenowii) is limited in south central Kentucky-Due to the hot summers, mild winters and a 200-day long growing season in Kentucky, herbage quality as well as management practices may differ from those reported in research from other climates. The objective of this study was to evaluate the nutritive quality of five forages (Matua, Gala, Smooth bromegrass, Tall fescue and Orchardgrass). The experiment was conducted on a Pembroke silt loam (fine-silty, mixed, mesic mollic Paleudalfs) in south central Kentucky as well as in the greenhouse. Four harvests each were obtained from the …

The Real Cost Of Beef: A Monetary Assessment Of The Environmental Degradation Caused By Beef Production, Carolyn Babcock

UNLV Theses, Dissertations, Professional Papers, and Capstones

The environmental degradation caused by beef production is severe. The current literature assesses the ecological damage, but falls short of assigning a per pound dollar amount to reflect the real cost of beef. In the United States, most of the environmental focus has been centered around the use of public lands for grazing and the grazing fee the government considers appropriate. The fee covers the maintenance of the grazing program, which includes maintenance of the actual land. This paper will concentrate on beef-related environmental degradation and select specific damage for monetary valuation.

The Method Of Radicle Emergence In Phytolacca Americana (Pokeweed), Staci A. Van Winkle

Honors Theses

Germination is a key element in the development of a plant. This process encompasses several stages, one of which is the elongation of the radicle tip. This process has been noted to occur by different methods such as rapid mitotic division or cell elongation. However, such a mechcmism has not been studied in Phytolacca americana (pokeweed). It was the intention of this study to observe at the cellular level the nature of the Phytolacca americana radicle during normal germination. This was done using a routine histological microtechnique which involves embedding in paraffin and sectioning with a microtome. The sections were …

Issues Concerning The Eradication Or Establishment And Biological Control Of The Mediterranean Fruit Fly, Ceratitis Capitata(Wiedemann) (Diptera: Tephritidae), In California, David H. Headrick, Richard D. Goeden

Horticulture and Crop Science

Classical biological control is suggested as a tool worth developing now for possible future use in the integrated pest management of the Mediterranean fruit fly (Medfly), Ceratitis capitata (Wiedemann), in California. Three factors that impact broadly on developing and implementing such a biological control program are: (1) the question of Medfly establishment, (2) quarantine considerations, and (3) agricultural and urban concerns. Each of these factors and their combined effects must be considered when discussing biological control of Medfly in California as shaped by historical perspectives on Medfly invasions, methods of Medfly eradication, and past biological control efforts against Medfly. We …

Wildlife As Natural Enemies Of Crop Pests, Ron J. Johnson, James R. Brandle, Natalie Sunderman, Rebecca Fitzmaurice, Nancy A. Beecher, Ronald M. Case, Mary Dix, Linda J. Young, Mark O. Harrell, Robert J. Wright, Laurie Hodges

Triennial National Wildlife and Fisheries Extension Specialists Conference: 8th (1996)

One asset of wildlife to landowners is the potential but understudied role of birds and other species as endemic natural enemies of crop pests. Enhancing such natural enemies as part of sustainable agricultural systems offers promise for maintaining agricultural competitiveness while providing wildlife habitat in intensively farmed areas. The University of Nebraska has established an agroforestry research team to address interdisciplinary questions and outreach associated with this topic. Included are studies of bird, mammal, and insect use of woody and herbaceous corridors and adjacent cropfields in east-central Nebraska. Uncultivated areas needed to sustain natural enemies of crop pests also provide …

Tip Blight

Tip blight, caused by the fungus Sphaeropsis sapinea (formerly Diplodia pinea), is a serious disease of mature Austrian, Scots (Scotch), and Mugo pines in Kentucky. In the landscape, tip blight is normally not observed until pines reach about 12 years old and begin to bear cones. Severe infections year after year can greatly weaken and eventually kill affected pines.

Isolation From Soil Microorganisms That Are Inhibitory To Wheat Seeding Pathogens, Kynita Wilson-Humphrey

McCabe Thesis Collection

Many diseases caused by bacteria, viruses, or fungi are responsible for the ruin of a great number of crops annually. At present, many of these crops are being treated for diseases by synthetic or man-made chemicals. Some of the chemicals have been proved to have adverse effects on the environment, including humans and animals. Very few non-chemical means are available to farmers at this time to control these pathogens. This is due to the fact that many of the means of control have little effect against the pathogens or diseases. This research attempts to isolate microorganisms from the soil which …
