Germplasm And Cultivar Development, M. D. Casler, Jeffrey F. Pedersen, G. C. Eizenga, S. D. Stratton

Department of Agronomy and Horticulture: Faculty Publications

Cool-season forage grasses have evolved, and continue to evolve, in natural ecosystems subject to environmental factors both in the presence and absence of human influences. The literature often lacks facts describing the evolution and domestication of forage grasses. Furthermore, the literature on this subject mainly deals with evolution of species in the broad scope, i.e., on a scale of hundreds of thousands or millions or years. Thus, some of our conclusions are necessarily speculative and are highly subject to the nature of the research that has been reported. We describe the forces of selection that act upon cool-season forage grasses …

Prediction Of Simulator Sickness In A Virtual Environment, Eugenia M. Kolasinski

Retrospective Theses and Dissertations

Sickness induced by Virtual Reality (VR) devices poses a genuine threat to the viability of this new technology and its potential products. If the occurrence or severity of sickness could be successfully predicted based on characteristics of an individual, at-risk users could be identified, properly warned, and, perhaps, trained in some way to reduce their risk. A Personal Computer-based VR system was used to address the prediction of simulator sickness. Phase I investigated four characteristics of an individual - age, gender, mental rotation ability, and pre-exposure postural stability - which were hypothesized to be predictive of sickness. Sickness measured as …

Cattle, Co-Wives, Children, And Calabashes: Material Context For Symbol Use Among The Il Chamus Of West-Central Kenya, Alan J. Osborn

Department of Anthropology: Faculty Publications

This paper examines systemic contexts for symbol use among the Maa-speaking Il Chamus in the Lake Baringo region of west-central Kenya. The systemic context for symbols and material culture consists of the environmental constraints and behavioral responses that characterize pastoralist life in East Africa. The author's interest in this problem developed in response to Ian Hodder’s work among the Il Chamus, Pokot, and Tugen in the Baringo District. Unlike Hodder, however, the author argues that symbols and their use in East Africa can be more productively explained from a materialist perspective. Specifically, it is proposed that symbols affixed to certain …

Embryonal Survival To 6 Days In Mice Selected On Different Criteria For Litter Size, E. L. De A. Ribeiro, M. A. J. Van Engelen, Merlyn K. Nielsen

Department of Animal Science: Faculty Publications

Embryonal survival was compared in mice resulting from four criteria of selection: LS = selection on number born; IX = selection on an index of ovulation rate and ova success; UT = selection on number born to unilaterally ovariectomized females; and LC = unselected control. Selection occurred for 21 generations with three replicates of the four criteria; thereafter, relaxed selection was practiced. The evaluation was performed using mice of two replicates at Generation 35 and one replicate at Generation 36. Data on a total of 289 female mice were recorded. Females, at an average age of 9 wk, were mated …

Range Or Meadow Regrowth Grazing And Weaning Effects On Two Year-Old Cows, James Lamb, Don C. Adams, Terry J. Klopfenstein, Greg Lardy

Nebraska Beef Cattle Reports

Body condition of cows at calving affects pregnancy rate and breeding date. Body condition at calving of spring calving cows wintered on range is influenced by fall body condition. A Montana study showed that lactating cows grazing range lost body condition during August and September. The loss of body condition was attributed to an inadequate consumption of crude protein. Diet samples of cattle grazing Sandhills range during August to October contain 6% to 8% crude protein. Loss of body condition of spring calving, primiparous cows grazing Nebraska Sandhills range during the fall is a concern. Subirrigated meadow regrowth is a …

Effect Of Variance Of Interaction Effects Of Sire And Herd On Selection For Milk And Fat Yield, G. Dimov, Jeffrey F. Keown, L. Dale Van Vleck, H. D. Norman

Department of Animal Science: Faculty Publications

The animal model for genetic evaluations of dairy cattle by the USDA currently includes a term for interaction effects of sire and herd. The relative magnitude of the variance of that effect was established in the 1960s as 14% of the total variance, but recent research has shown that the proportion is 2% or less. This report compared EBV using either the 14% or the actual estimate from 20 samples of records from herds in California, New York, and Pennsylvania. From 6 to 22% of bulls or cows selected for milk and fat yields based on evaluation with 14% of …

Habitat And Courtship Behavior Of The Wolf Spider Schizocosa Retrorsa (Banks) (Araneae, Lycosidae), Eileen Hebets, Gail E. Stratton, Gary Miller

Eileen Hebets Publications

The habitat and courtship behavior of the wolf spider Schizocosa retrorsa (Banks 1911) were studied and are described here for the first time. The range of S. retrorsa was extended to include the lower peninsula of Michigan. This species is locally abundant in highly exposed habitats of sand or pine litter. Male courtship consists of chemoexploration, palpal drumming, an extended leg tap, and a "push-up" display. Female displays include a double leg arch, approaches, and orientations toward the male.

G96-1293 Feedlot Abandonment Recommended Procedures, Richard K. Koelsch, Gerald R. Bodman

University of Nebraska-Lincoln Extension: Historical Materials

An abandoned animal feeding facility is a significant threat to the environment. Procedures to minimize the risk are discussed.

Feedlot abandonment occurs for various reasons, including economic and social changes, environmental concerns, consolidation for more cost effective management and operation, and modification of personal goals. Whether a feedlot is abandoned for a short time until some crisis passes, or permanently, steps are necessary to minimize the risk of environmental degradation.

Under both scenarios, an abandoned feedlot poses an immediate threat to surface and groundwater quality. The unused facility is also a potential nuisance and source of health problems for humans …

Ec96-1555 Insect Pest Management Strategies For Yards And Gardens, Frederick P. Baxendale, Robert J. Wright

University of Nebraska-Lincoln Extension: Historical Materials

A growing awareness of problems associated with overusing pesticides has prompted many home gardeners and landscape managers to seek alternative methods of insect control. Integrated pest management (IPM) uses suitable methods in a compatible manner to maintain pest densities below levels of unacceptable injury.

IPM principles can be applied to all pest groups (insects, mites, weeds, plant diseases and vertebrates), and urban as well as agricultural settings. This publication will discuss how integrated pest management can be applied to insect and mite management in yards and gardens.

G96-1295 Scabies, Wayne L. Kramer, Donald E. Mock

University of Nebraska-Lincoln Extension: Historical Materials

The life cycle, symptoms, diagnosis, and treatment of scabies infestations in humans is addressed.

Scabies is a contagious disease of humans and other mammals. It is caused by the mite, Sarcoptes scabiei, which burrows into the dead layer of the human skin (stratum corneum). Sarcoptic mites are obligate parasites which spend most of their lives in burrows in the skin. If the mite invades a person's skin, and establishes itself, symptoms of scabies will become apparent, although it may take four to six weeks.

Scabies is transmitted from person to person by close personal and prolonged skin contact. Transmission also …

G96-1308 Management Of Eastern Redcedar On Grasslands, John Ortmann, James L. Stubbendieck, George Pfeiffer, Robert A. Masters, Walter H. Schacht

University of Nebraska-Lincoln Extension: Historical Materials

Developing an integrated control program including prescribed burning, herbicides, and cutting may be the best way to control eastern redcedar in Nebraska, according to recent research. Eastern redcedar is a serious threat to grassland productivity. Some control methods may be too expensive to use on grasslands, but in many cases, an integrated approach combining fire with more intensive follow-up methods will provide reasonable control at an acceptable cost.

G96-1307 Bioengineering For Hillslope, Streambank And Lakeshore Erosion Control, Thomas G. Franti

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes bioengineering techniques for hillslope, streambank and lakeshore erosion control. Tips for a successful bioengineering installation and demonstration project are described. Soil erosion occurs whenever water meets land with enough force to move soil. Often this occurs along streambanks and lakeshores or where excess water flows over hillslopes. While streambank and hillslope erosion can be dramatic, especially after large rainfalls or floods, normal streamflows, excess runoff from urbanized areas and wave action along lakeshores continually erode soil. Erosion can be severe, as is the case in many man-made lakes, where shorelines are composed of easily erodible soil. Traditional …

Use Of The Polymerase Chain Reaction For Salmonella Detection, J. Kwang, E. T. Littledike, J. E. King

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

A primer set of oligonucleotides (S18 and S19) from the ompC gene of Salmonella has been evaluated for specific detection of Salmonella by polymerase chain reaction (PCR). This primer set successfully amplified 40 Salmonella serovars (60 isolates), but not 24 non-Salmonella bacteria (42 isolates) that have been tested so far. The uniqueness of these primer sequences was also confirmed. The sensitivity of PCR detection in extracted chromosomal DNA for Salm. typhimurium was 1 pg. The sensitivity for boiled whole bacteria was 400 cells. The detection of Salm. typhimurium in ground beef samples required 4-6 h enrichment with an initial inocula …

Ec96-142 Conservation Reserve Program: Crp Land Use Guide, Douglas Anderson

University of Nebraska-Lincoln Extension: Historical Materials

Conservation Reserve Program (CRP) contracts held by Nebraska producers will begin to expire in 1996. Thousands of acres of grassland will be eligible for haying, grazing or to be returned to other uses. Land-use decisions made by owners and operators will impact the economic viability and long-term productivity of individual farms, as well as the region as a whole.

The intent of the CRP Land Use Guide is not to provide all of the answers, in many instances we don't even know the questions. It is, however, intended to provide an outline of the key issues you will face when …
