Review Of Principles Of Geoarchaeology: A North American Perspective By Michael R. Waters, Rolfe D. Mandel

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

First published in 1992, this book-now in paper-presents the fundamentals of geoarchaeology, the field of study that applies the concepts and methods of the geosciences to archaeological research. Although a number of good books have been written about this subdiscipline of archaeology, Waters restricts his review to late Quaternary landscapes in North America. Furthermore, he limits his discussion to the field aspects of geoarchaeology. Stratigraphy, site formation processes, and landscape reconstruction are the centerpieces of this study. Readers looking for information about laboratory methods, dating techniques, or the application of geophysics and geochemistry to archaeology must go to other sources. …

Grassland Birds And Habitat Structure In Sandhills Prairie Managed Using Cattle Or Bison Plus Fire, Randall Griebel, Stephen L. Winter, Allen Steuter

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

Grassland birds are known to respond to specific changes in habitat structure, such as plant height and density. However, the response of grassland bird communities to management induced changes in the regional habitat mosaic are less well understood. Grazing by ungulates and fire regimes play an important role in defining the habitat mosaic in the Great Plains. We provide information on bird abundance, distribution, and habitat structure from similar sandhill prairie landscapes managed traditionally with grazing by cattle (Bos taurus) and by a dynamic bison (Bos bison)-plus-fire regime. Although the two management regimes are dissimilar, only …

Review Of The Science Of Conservation Planning: Habitat Conservation Under The Endangered Species Act By Reed F. Noss, Michael A. O'Connell, And Dennis D. Murphy, Craig A. Davis

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

The Science of Conservation Planning is a well-written book that proclaims the need for rigorous science in habitat conservation planning. I found it particularly relevant in light of the push for developing more habitat conservation plans (HCPs) to mitigate habitat losses for endangered species. The authors' considerable experience in developing and evaluating HCPs is evident in their thorough evaluation of the entire habitat conservation planning process and in their science-based recommendations for improving habitat conservation planning.

Review Of The Tallgrass Restoration Handbook: For Prairies, Savannas, And Woodlands Edited By Stephen Packard And Cornelia F. Mutel, Douglas H. Johnson

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

Prairies have been termed the nation's most endangered ecosystem. Tallgrass prairies especially have been converted to cultivation; most states have lost ninety-eight percent or more of the tallgrass prairie that existed before European settlement. The rich soils that tallgrass vegetation created over millennia led to the prairies' replacement by the Corn Belt in a matter of mere decades.

While most persons, rather than mourning the passing of tallgrass prairie, are contented with the vistas of grains and soybeans that displaced it, some conservationists are attempting to stem the tide of habitat loss, and others are going so far as trying …

Evaluating Measures Of Family History Of Alcoholism: Density Versus Dichotomy, Scott F. Stoltenberg, Sharon A. Mudd, Frederic C. Blow, Elizabeth M. Hill

Department of Psychology: Faculty Publications

Aims: Studies have used myriad measures of family history of alcoholism (FH) making it difficult to compare them directly. Commonly used FH measures partition samples into the well-known positive (FH+) and negative (FH–) dichotomy, although quantitative measures of density potentially provide more information. A standard FH measure would facilitate between-study comparisons. The purpose of this study is to evaluate a quantitative FH measure, called Family History Density (FHD), that has theoretical and practical advantages over currently used measures. Design: Logistic regression equations were estimated for FHD and six commonly used FH measures on alcohol dependence diagnosis and two measures of …

Beneficial Arthropods Associated With Buffalograss, Tiffany Heng-Moss, Frederick P. Baxendale, Terrance P. Riordan

Department of Entomology: Faculty Publications

Beneficial arthropods collected from buffalograss, Buchloe dactyloides (Nuttall) Engelmann, evaluation plots and vegetatively established buffalograss lawns included predatory ants, spiders, ground beetles, rove beetles, big-eyed.bugs, and several species of hymenopterous parasitoids. Ants and spiders were the most abundant beneficial arthropods collected, representing 84% of the total beneficial arthropods captured. Pitfall traps collected >2.5 times as many (16,094) beneficial arthropods as sod plug samples (6,054), demonstrating that pitfall traps are a more effective technique than sod plugs for capturing highly mobile surface-dwelling arthropods. Families of parasitoids captured on sticky traps during the 2-yr sampling period included Scelionidae, Encyrtidae, Mymaridae, and Trichogrammatidae. …

A Protein Encoded By The Latency-Related Gene Of Bovine Herpesvirus 1 Is Expressed In Trigeminal Ganglionic Neurons Of Latently Infected Cattle And Interacts With Cyclin-Dependent Kinase 2 During Productive Infection, Yunquan Jiang, Ashfaque Hossain, Mariah Teresa Winkler, Todd Holt, Alan R. Doster, Clinton J. Jones

School of Veterinary and Biomedical Sciences: Faculty Publications

Despite productive viral gene expression in the peripheral nervous system during acute infection, the bovine herpesvirus 1 (BHV-1) infection cycle is blocked in sensory ganglionic neurons and consequently latency is established. The only abundant viral transcript expressed during latency is the latency-related (LR) RNA. LR gene products inhibit S-phase entry, and binding of the LR protein (LRP) to cyclin A was hypothesized to block cell cycle progression. This study demonstrates LRP is a nuclear protein which is expressed in neurons of latently infected cattle. Affinity chromatography indicated that LRP interacts with cyclin-dependent kinase 2 (cdk2)-cyclin complexes or cdc2-cyclin complexes in …

Track Structure Model For Radial Distributions Of Electron Spectra And Event Spectra From High-Energy Ions, F. A. Cucinotta, Robert Katz, J. W. Wilson

Robert Katz Publications

An analytic method is described for evaluating the average radial electron spectrum and the radial and total frequency-event spectrum for high-energy ions. For high-energy ions, indirect events make important contributions to frequency-event spectra. The method used for evaluating indirect events is to fold the radial electron spectrum with measured frequency-event spectrum for photons or electrons. The contribution from direct events is treated using a spatially restricted linear energy transfer (LET). We find that high-energy heavy ions have a significantly reduced frequency-averaged lineal energy (YF) compared to LET, while relativistic protons have a significantly increased YF and dose-averaged lineal energy (YD) …

Ecological Evaluation For The West Ash Creek Potential Research Natural Area, Pine Ridge Ranger Unit, Nebraska National Forest, Steven B. Rolfsmeier

A Half-Century Of Winter Bird Surveys At Lincoln And Scottsbluff, Nebraska, Paul A. Johnsgard

Papers in Ornithology

Since 1900, the National Audubon Society has sponsored annual "Christmas bird counts" during the two-week period encompassing Christmas; and as a result, long-term data on winter bird populations have accumulated, especially for some locations. The first two such counts in Nebraska were made in 1909 and in 1912 in Lincoln. Beginning in 1947 and continuing to the present, an unbroken series of counts were made in Lincoln, usually by members of the Uni¬versity Place Bird Club, the Audubon Naturalist's Club, or the Wachiska chapter of the National Audubon Society. For Scottsbluff, an unbroken set of counts extends from 1949 to …

Sprinkler Irrigation As A Voc Separation And Disposal Method: Innovative Technology Evaluation Report, Teri Richardson, Paul Depercin, Douglas Grosse, Rena Howard, Ann Kern, Endalkachew Sahle-Demissie, Johnny Springer Jr., Richard Schlenker, Roy F. Spalding

United States Environmental Protection Agency: Publications

This report summarizes the findings of an evaluation of sprinkler irrigation as a volatile organic compound (VOC) separation and disposal method.

Background A need for lower cost, effective treatment alternatives for the disposal of treated contaminated groundwater provided the impetus to conduct a SITE demonstration of sprinkler irrigation since it provides both separation and disposal options. Since the application of irrigation is fairly widespread throughout the United States, there may be an opportunity to employ this as a dual purpose technology; concurrent irrigation and disposal of treated groundwater. In order to determine whether this option is viable, it is necessary …

1998 Midwinter Eagle Survey For Nebraska Including Summary Tables For The 1980-1998 Period From The Nebraska Game And Parks Commission, John J. Dinan

Nebraska Bird Review

Mild temperatures were prevalent in the weeks prior to this year's survey; however, temperatures cold enough to form a thin layer of ice on some reservoirs and lakes occurred between aerial surveys. Three of the aerial surveys were conducted on the 6th and 7th of January and one was conducted on the 13th. The survey route that includes the Platte River from Kearney to Plattsmouth and the Loup River was not surveyed this year because of persistent foggy conditions.

Temperatures recorded during the 1998 survey were variable, ranging from 5 to 40 degrees F. The Niobrara River was 50 to …

Book Review: Baby Bird Portraits By George Miksch Sutton: Watercoiors In The Field Museum By Johnsgard, P. A. (1998), John J. Janovy Jr.

Nebraska Bird Review

George M. Sutton's baby bird portraits are his most captivating works. The subjects are isolated against a stark, raw-paper background, and they stare out at the viewer with eyes typically naive but alert. Sutton's artistic mastery of the foot is integral to the underlying biology in these pictures: sturdy and sure against the table for a ruffed grouse, curled inward and near useless for a gallinule on dry land, and almost casually clutching a twig, the hallux resting loosely, for a newly fledged grosbeak. The match between these pictures and Paul Johnsgard's text is perfect. In his first two paragraphs, …
