Predator Management To Increase Duck Nest Success, Harold A. Doty, Anthony J. Rondeau

Great Plains Wildlife Damage Control Workshop Proceedings

Operational programs of seasonal predator management to increase duck production may be economically feasible. Mammalian predators of nesting ducks and their eggs were reduced in numbers on selected areas of west central Minnesota during the nesting seasons 1982-86. Where predators were removed, nest success averaged 30% while nest success on nearby untreated habitat was 10%.

Plagues Of The House Mouse In South Eastern Australia, Glen Saunders

Vertebrate Pest Conference Proceedings: 12th (1986)

Plagues of the house mouse (Mus musculus) occur at irregular intervals throughout the agricultural regions of south-eastern Australia. This paper discusses these phenomena in terms of their impact on agricultural production, previous attempts to reduce damage and levels of infestation, and associated environmental implications. Consideration is also given to the accurate prediction of mouse plagues and the control strategies which need to be in place if effective management is to become a reality.

Why Do Possums Survive Aerial Poisoning Operations?, D. R. Morgan, C. L. Batcheler, J. A. Peters

Vertebrate Pest Conference Proceedings: 12th (1986)

Major causes of failure of aerial poisoning operations against possums identified were: sublethal toxic loading, undersize sublethal baits, nonlearned behavioral aversion to 1080, and failure to encounter bait. Dislike of bait was not a major cause of failure.

Progress has been made towards solving these problems, but failure to encounter bait remains a likely major reason for possums surviving aerial poisoning. Improvements in the aerial sowing of bait are essential if the full benefit of this progress is to be realized.

Amino Sugars In The Glycoprotein Toxin From Bacillus Thuringiensis Subsp. Israelensis, Mary Ann Pfannenstiel, Ganapathy Muthukumar, Graham A. Couche, Kenneth W. Nickerson

Papers in Microbiology

The carbohydrate content of purified Bacillus thuringiensis subsp. israelensis crystal toxin was determined by six biochemical tests, column chromatography on an amino acid analyzer, and the binding of 11 fluorescent lectins. The crystals contained approximately 1.0% neutral sugars and 1.7% amino sugars. The anmino sugars consisted of 70% glucosamine and 30% galactosamine. No N-acetylneuraminic acid (sialic acid) was detected. The presence of amino sugars was confirmed by the strong binding of fluorescent wheat germ agglutinin and the weak binding of fluorescent soybean agglutinin. These lectins recognize N-acetyl-D-glucosamine and N-acetyl-D-galactosamine, respectively. The lectin-binding sites appeared evenly distributed among …

The Relationship Of Temperament To Tolerance Of Cold And Heat: Beyond “Cold Hands-Warm Heart”, Richard A. Dienstbier, Robert L. Laguardia, Noreen S. Wilcox

Department of Psychology: Faculty Publications

Thermal regulation and peripheral arousal in episodes of emotion are dependent upon similar autonomic and hormonal processes. Thermal-tolerance measure were developed and validated in order to indirectly assess adrenergic (cold tolerance) and cholinergic (heat tolerance) responsivity. We hypothesized that cold tolerance would correlate with reduced emotionality (largely fear and anxiety) and depression, and with increased stimulus seeking and dispositions toward activity; those hypotheses were confirmed. Tentatively advanced hypotheses that heat tolerance would correlate with reduced depression and emotional states were not confirmed, but heat tolerance was positively associated with activity and (weakly) with some of the same dimensions of temperament …

This chapter documents climate-related impacts that occurred in the United States (Fig. 13.1) during 1982-83. Many of these impacts have been rightly or wrongly attributed to El Niño. The impacts of the summer drought and heat wave in the central United States and the decline of the fishing industry along the northwestern coast of the United States are discussed in greater detail.

Chapfer2 Understanding The Drought Phenomenon: The Role Of Definitions, Donald A. Wilhite, Michael H. Glantz

National Drought Mitigation Center: Faculty Publications

The occurrence of widespread, severe drought in Africa, India, North America, China, the USSR, Australia, and western Europe has once again underscored the vulnerability of developed and developing societies to drought The occurrence of severe drought during 1982-83 is shown in Fig. 1. These recent droughts have emphasized the need for more research on the causes as well as the impacts of drought and the need for additional planning to help mitigate the possible worst effects of future droughts. Drought has been the subject of a great deal of systematic study, particularly reconstructions of drought history, computations of drought frequency, …

G87-838 Management Of Greenbugs In Sorghum (Revised May 1994), Robert J. Wright, Stephen D. Danielson, Zb Mayo

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes the identification, biology and management options for greenbugs in Nebraska sorghum.

The greenbug is the most important insect pest of grain and forage sorghums in Nebraska. Although numbers fluctuate from year to year, greenbugs are a limiting factor to sorghum yield in most years. Their management is complicated by the fact that greenbugs have been able to evolve populations capable of overcoming plant resistance and organophosphate insecticides, so best management practices continue to change over time.

Another common aphid found in sorghum is the corn leaf aphid. Corn leaf aphids are often mistaken for greenbugs; however, they …

G87-834 Leafy Spurge (Revised February 1989), R.S. Moomaw, Alex Martin, R.N. Stougaard

University of Nebraska-Lincoln Extension: Historical Materials

Identification and control of leafy spurge, a noxious weed established in about three-fourths of Nebraska's counties, is discussed here.

Leafy spurge, (Euphorbia esula L.) introduced to the United States from Eurasia in 1827, has become a troublesome weed in North Dakota, South Dakota, Wyoming, Montana and Nebraska.

Leafy spurge is found in about three-fourths of Nebraska's counties. It is most common in the state's northern and eastern areas. Leafy spurge is found primarily on untilled land such as pastures, range, roadsides, woodlands and farmsteads. Leafy spurge is a noxious weed according to the Nebraska Seed Law and the Nebraska …

Quinoline Sorption On Na-Montmorillonite: Contributions Of The Protonated And Neutral Species, Calvin C. Ainsworth, John M. Zachara, Ron L. Schmidt

United States Department of Energy: Publications

Dilute aqueous solutions of quinoline were contacted with Na-montmorillonite to elucidate the sorption process of the neutral and protonated species. Sorption occurs via a combination of ion exchange and molecular adsorption and yields S-type isotherms. Exchange between the quinolinium ion (QH⁺ and Na can be described by means of Vanselow selectivity coefficients and a thermodynamic exchange constant (K_ex). Due to the apparent adsorption of the neutral species at high mole fractions (x) of the solid phase, the thermodynamic standard state was defined as 0.5 mole fraction. The selectivity at pH ~4.95 of the QH⁺ species over …

Sorption Of Binary Mixtures Of Aromatic Nitrogen Heterocyclic Compounds On Subsurface Materials, John M. Zachara, Calvin C. Ainsworth, Christina E. Cowan, Berta L. Thomas

United States Department of Energy: Publications

Single and binary solute sorption of pyridine, quinoline, and acridine has been investigated on two low organic carbon subsurface materials with similar properties but different equilibrium pH when saturated with water. Single solute sorption for all compounds is higher in the acidic soil as compared to the basic soil, reflecting stronger sorption of the protonated organic cations. The protonated species exhibit high selectivity for the exchange complex at low aqueous concentration with selectivity increasing with ring number. Binary sorption experiments with quinoline/pyridine and quinoline/acridine demonstrate that competitive sorption occurs between compounds in the acidic subsoil where the protonated compound species …

Bioconcentration Of Heavy Metals (Cu, Cr, Pb, And Zn) In The Missouri River Near Sioux City, Iowa, Robert Conklin, Suzie Galles, Edward Shane, Rod Tondreau

United States Army Corps of Engineers, Omaha District

The concentrations of the heavy metals- copper, chromium, lead, zinc- in the biota of the Missouri River were measured at a control site upstream of Sioux City and at a site downstream of the city. Bioconcentration factors for each of the metals were calculated for fish, periphyton, and invertebrates, and the concentrations of metals in the river sediments were measured.

Concentrations of the same metals were measured in the sediment, water, periphyton, invertebrates, zooplankton, and fish of Snyder's Bend Lake. Bioconcentration factors were calculated for each of the biological communities and were found to be very similar to those found …

The Confinement Of Juveniles In Nebraska Jails And Lockups, Lorie A. Fridell, Vincent J. Webb

Center for Public Affairs Research (UNO): Publications

Using adult jails and lockups for confining youths is a major issue in juvenile justice. Proponents of removing children from these facilities are concerned with the conditions of confinement, the .ate of suicide among youths held in adult facilities, the excessive use of secure confinement for youths, and the legal liability of jurisdictions that hold juveniles in adult facilities. Nebraska has made significant progress in reducing the number of youths confined in adult jails and lockups, but has yet to pass legislation or develop programs and facilities to complete the task. Policy options for reducing the use of secure confinement …

Financing Public Elementary And Secondary Schools In Nebraska, C. Cale Hudson, Katherine Lewellan Kasten

Center for Public Affairs Research (UNO): Publications

Nebraska's system for funding public schools is deteriorating. Shifts in population, variations in tax capacity, and changes in the mission defined for public schools make the current system inadequate and inequitable. Funding problems are compounded by the large number of school districts which divide human and financial resources in the state unequally. Problems in the finance system are described, and suggestions for determining the minimum education program to be funded, the most cost-effective organization of school districts, measures for fair acquisition of funds, and procedures for equitable allocation of state aid to public schools are discussed.
