A Review Of White-Tailed Deer Movements In The Great Plains Relative To Environmental Conditions, Kurt C. Vercauteren, Scott E. Hygnstrom

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Movements of white-tailed deer (Odocoileus virginianus Rafinesque) in the eastern Great Plains and Midwest were examined. The proportion of deer that move between distinct summer and winter home ranges varies among different populations. Seasonal migration between home ranges is influenced primarily by phenological period, agricultural activities, and the availability of cover and food. Corn provides a nearly unlimited source of cover and food in summer and early fall. In late fall and early winter, deer move to areas of permanent cover, such as wooded river bottoms, draws, or slopes. Hunting, crop harvest, or seasonal change may influence deer movements …

Sensitivity Of Streamflow To Climate Change: A Case Study For Nebraska, Clinton M. Rowe, Karl C. Kuivinen, Francisco Flores-Mendeza

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Climate change, whether natural or due to human action, will have an impact on many aspects of our environment. The nature of streamflow changes will depend on the magnitude and direction of the climate change. However, since the principal climatic factors that control streamflow are precipitation and evapotranspiration (which can be estimated from air temperature data), the sensitivity ofstreamflow to variations in climate can be studied through the use of plausible scenarios of climate change.

A simple water budget model was used to reconstruct streamflow from monthly temperature and precipitation data for locations within and immediately surrounding the Little Blue …

Quantifying The Effect Of Technology And Management On Wheat Yields In The Western Great Plains, Elizabeth Law-Evans, Paul A. Kay

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

The relative influences of interannual climate variability, technological development, and management strategies on crop yields are difficult to separate. Assessment of climate impacts and of an agricultural system s ability to protect crops from weather-related yield changes are important questions receiving considerable attention in view of the potential for climate change. Statistical and ecological crop-climate studies have assumed that the combined effects of technology and management have produced linear or exponential yield increases in most crops in recent years.

In this study, an empirical assessment of influences of management and technology on wheat yields in north-central Colorado was made using …

Review Of Science With Practice: Charles E. [Edwin] Bessey And The Maturing Of American Botany By Richard A. Overfield, Linda Johnson Rossi

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Science with Practice thoroughly treats the professional life of Charles Edwin Bessey, a prominent nineteenth-century American scientist, professor, and educational reformer, who helped to lay the foundation of modern plant biology. The book focuses on Bessey as a prime promoter of the laboratory as an important learning center in college and university teaching of botany and agriculture. Bessey used his broad knowledge of plant classification to innovate the Bessey System, one that is still in use. It explains Bessey in the context of American botany-student of Asa Gray and intellectual forebear of the American botanists Roscoe Pound, Pier A. Rydberg, …

Echinococcus Granulosus (Taeniidae) And Autochthonous Echinococcosis In A North American Horse, Eric P. Hoberg, S. Miller, M. A. Brown

Harold W. Manter Laboratory of Parasitology: Faculty Publications

We report the first documented case of autochthonous echinococcosis in a horse of North American origin. Three fully maturll and viable unilocular hydatid cysts of Echinococcus granulosus (Batsch, 1786) were an incidental finding at necropsy in the liver of a 14 year-old gelding thoroughbred that had been foaled in Virginia and raised in Maryland. Protoscolices were armed with two rows of 28-37 rostellar hooks; small hooks measured 23-30 μm; large hooks measured 26-33 μm. Morphologically, these were compatible with rostellar armature considered typical for the equine strain of E. granulosus currently known primarily from the United Kingdom. This horse had …

A New Species Of Heterorhabditis From The Hawaiian Islands, Scott Lyell Gardner, S. Patricia Stock, Harry K. Kaya

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A new species of nematode of the genus Heterorhabditis (Nemata: Heterorhabditidae) was found during a survey of the soil entomopathogenic nematode fauna of the Hawaiian Islands. Heterorhabditis hawaiiensis sp. n. can be separated from all other species of Heterorhabditis by the length of the infective juvenile and the morphological characters of the spicules, gubemaculum, and bursa. Random amplified polymorphic DNA (RAPD) fragment analysis showed that this species also has a distinct genetic pattern in RAPD bands relative to the other 6 species or isolates of Heterorhabditis that were compared.

Meloidogyne Javanica Parasitic On Peanut, E. K. Tomaszewski, M. A. M. Khalil, A. A. El-Deeb, Thomas O. Powers, J. L. Starr

Department of Plant Pathology: Faculty Publications

Peanut fields in four governorates of Egypt were surveyed to identify species of Meloidogyne present. Fourteen populations obtained from peanut roots were all identified as M. javanica based on perineal patterns, stylet and body lengths of second-stage juveniles, esterase phenotypes, and restriction fragment length polymorphisms of mtDNA. Three of 14 populations, all from contiguous fields in the Behara governorate, had individuals with a unique two-isozyme esterase phenotype. All populations of M. javanica tested on peanut had levels of reproduction on the M. arenaria-susceptible peanut cultivar Florunner that were not different from M. arenaria (P = 0.05), and had lower …

Who Wants To Stop The Church: Homosexual Rights Legislation, Public Policy, And Religious Freedom, Richard F. Duncan

Nebraska College of Law: Faculty Publications

Religions that make peace with the spirit of the age have little to fear from the rulers of the day. But believers who refuse to adapt their religious practices to the Zeitgeist are vulnerable under Smith, unless the Court decides to protect religious pluralism by giving full scope to Smith's exceptions.

I have tried to show that homosexual rights legislation imposes heavy costs on the right of employers and landlords to take character into account when making business decisions. These costs are particularly heavy when borne by religiously-motivated persons, who are declared outlaws merely for trying to obey God …

A New Legal Regime For Bilateral Assistance Programs: International Agreements Governing The "Nunn-Lugar" Demilitarization Program In The Former Soviet Union, Jack M. Beard

Nebraska College of Law: Faculty Publications

On December 12, 1991, President George Bush signed into law an unprecedented piece of legislation popularly referred to as the "Nunn-Lugar Act" in honor of the Act's principal sponsors, Senators Sam Nunn and Richard Lugar.¹ The Act, which Congress has enlarged with subsequent legislation² and funded with authorization and appropriations acts providing up to $1.6 billion over the course of four years,³ created a complicated legal and fiscal framework to use United States Department of Defense resources to provide assistance to states of the former Soviet Union in order to facilitate the demilitarization of the former Soviet …

The Effects Of Requiring Different Response Strategies Following Caching In Clark’S Nutcrackers (Nucifraga Columbiana), Alan Kamil, Russell P. Balda, Deborah J. Olson

Papers in Behavior in Biological Sciences

Clark’s nutcrackers use spatial memory to recover stored food in the field and have performed very well in laboratory tests of spatial memory. During the present experiment, two groups of nutcrackers cached seeds every 4 days. Following each cache session, the stay group was tested with seeds in their caches; the shift group found seeds in novel sites. The stay group performed accurately throughout the experiment, but the shift group gave no indication of being able to learn to avoid sites where they had stored seeds. These results suggest that although nutcrackers can learn to shift away from remembered locations …

Dose, Robert Katz

Robert Katz Publications

The universal use of dose as a normalizing parameter in radiobiology is based entirely on the availability of measuring instruments. It is a poor basis for predicting or understanding the relationship between an irradiation and the resulting end point. Energy deposited is not the cause of an interaction. It is a secondary effect. The interaction is best described by fluence and cross section. Energy deposited depends principally upon inelastic collision cross sections for the interaction of electrons with molecules. Especially for heavy-ion bombardments, for high-LET radiations, inelastic electron collision cross sections relate only remotely to the observed end points of …

Radiosensitivity Parameters For Lethal Mutagenesis In Caenorhabditis Elegans, F. A. Cucinotta, J. W. Wilson, Robert Katz

Identification And Characterization Of Aspergillus Nidulans Mutants Defective In Cytokinesis, Steven D. Harris, Jennifer L. Morrell, John E. Hamer

Department of Plant Pathology: Faculty Publications

Filamentous fungi undergo cytokinesis by forming crosswalls termed septa. Here, we describe the genetic and physiological controls governing septation in Aspergillus nidulans. Germinating conidia do not form septa until the completion of their third nuclear division. The first septum is invariantly positioned at the basal end of the germ tube. Block-and-release experiments of nuclear division with benomyl or hydroxyurea, and analysis of various nuclear division mutants demonstrated that septum formation is dependent upon the third mitotic division. Block-and-releasee xperiments with cytochalasin A and the localization of actin in germlings by indirect immunofluorescence showed that actin participated in septum formation. In …

Identification And Characterization Of A Protein Kinase Gene In The Lymantria Dispar Multinucleocapsid Nuclear Polyhedrosis Virus, David S. Bischoff, James M. Slavicek

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

The Lymantria dispar multinucleocapsid nuclear polyhedrosis virus (LdMNPV) gene encoding vPK has been cloned and sequenced. LdMNPV vPK shows a 24% amino acid identity to the catalytic domains of the eucaryotic protein kinases nPKC from rabbits, HSPKCE from humans, APLPKCB from Aplysia californica, and dPKC98F from Drosophila melanogaster, and homology to several other protein kinases from yeasts, mice, and bovines. The homology suggests that vPK is a serine/threonine protein kinase as defined by Hanks et al. (S. K. Hanks, A. M. Quinn, and T. Hunter, Science 241:42-52, 1988). Temporal expression studies indicate that vPK is expressed throughout the …

Out-Of-Season Births Of Elk Calves In Wyoming, Bruce L. Smith

United States Fish and Wildlife Service: Publications

ive out-of-season births of Rocky Mountain elk were documented over a 24-month period at the National Elk Refuge, Wyoming. One of four November neonates was radio-instrumented and subsequently died seven days later due to hypothermia. An April-born calf was killed by a coyote. Supplemental winter feeding of elk at the Refuge may increase the frequency of asynchronous reproduction.

A Contaminants Evaluation Of The Big Blue River In Southeastern Nebraska, Brent J. Esmoil, Kirk D. Schroeder, Timothy E. Fannin

United States Fish and Wildlife Service: Publications

We collected three composite fish and three composite sediment samples from the Big Blue River in southeastern Nebraska to determine the presence of agricultural chemicals or other contaminants. Inorganic analyses consisted of individual analyses for arsenic, selenium, and mercury, as well as an ICP scan for other elements. Organic analyses included organochlorines, polynuclear aromatic hydrocarbons, organophosphate and carbamate pesticides, and chlorphenoxy acid herbicides.

Arsenic was detected in the sediment samples, but not in the fish samples.

Selenium was detected in one of three sediment samples and in all fish samples.

Mercury was not detected in sediment samples, but was detected …

G94-1220 Controlling Ticks, John B. Campbell, Gustave D. Thomas

University of Nebraska-Lincoln Extension: Historical Materials

Identification and control of ticks common to Nebraska.

Ticks are members of the same phylum (Arthropoda) of the animal kingdom as insects, but are in a different class (Arachnida). The main difference is the body of a tick is composed of only two sections while insect bodies have three sections.

There are over 800 species of ticks, 100 of which are important to man and animals because of economic losses or disease transmission. Fortunately in the United States, only about 12 species are economically important because they transmit disease organisms (viral, bacterial, protozoan, and rickettsial) or cause economic losses to …
