Review Of Lewis And Clark And The Geology Of The Great Plains And Lewis And Clark And The Geology Of Nebraska And Parts Of Adjacent States By R. F. Diffendal, Jr., And Anne P. Diffendal, Harmon Maher, Jr.

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

When it comes to science in general, and the geology of the Great Plains in particular, there is arguably an imbalance between the wealth of material written for experts and the relative paucity written for the general public. These publications help correct that imbalance at a time when the various Lewis and Clark celebrations create an especially receptive and engaged audience.

Preliminary Assessment Of Sand Dune Stability Along A Bioclimatic Gradient, North Central And Northwestern Oklahoma, Carlos Cordova, Jess Porter, Kenneth Lepper, Regina Kalchgruber, Gregory Scott

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

Sandhills of eolian origin and currently active dunes in Oklahoma are located mainly on the northern side of the main rivers. Their longitudinal distribution spans a gradient of annual precipitation ranging from 914 mm in the east to 403 mm in the west. Vegetation types along this gradient include cross-timbers woodlands in the east and sand-sage and short grasses in the west. The information presented here is a preliminary assessment of sand dune dynamics and morphology, soils, and vegetation as the basis for an ongoing study on past and present processes of sand dune stability. For this purpose, six areas …

Resistant Turfgrasses For Improved Chinch Bug Management, Tiffany Heng-Moss, Frederick P. Baxendale, Robert C. Shearman, Thomas E. Eickhoff

Department of Entomology: Faculty Publications

Researchers at the University of Nebraska evaluated selected cool- and warm-season turfgrasses for resistance to chinch bugs in the Blissus complex, and documented the presence of multiple chinch bug resistance in these turfgrasses.

Greenhouse and field screening studies were initiated to search for cool- and warm-season turfgrasses with resistance to chinch bugs in the Blissus complex. Several warmseason turfgrasses (buffalograss, zoysiagrass, and bermudagrass) with resistance to the western chinch bug have been identified.

Studies are currently underway to investigate the biochemical and physiological mechanisms underlying resistant turfgrasses. This information is fundamentally important for formulating plant breeding strategies, and subsequently developing …

Breeding Bird Communities In Riparian Forests Along The Central Platte River, Nebraska, Craig Davis

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

The Platte River has changed from a nearly treeless prairie river to a heavily forested river. These habitat changes have likely benefited many woodland birds, but have harmed other migratory birds such as cranes. In response to this impact on migratory birds, conservation groups implemented a tree-clearing program to enhance habitat for these species. This practice is not without controversy because of concerns about its effect on woodland birds. The goal of this study was to determine the composition and abundance of breeding birds that use these forests and discuss the potential impacts of tree clearing on woodland birds. Surveys …

Changes In Summer Irrigated Crop Area And Water Use In Southeastern Turkey From 1993 To 2002: Implications For Current And Future Water Resources, Mutlu Ozdogan, Curtis E. Woodcock, Guido D. Salvucci, Hüseyin Demir

United States National Aeronautics and Space Administration: Publications

Changes in summer irrigated cropland acreage and related water use are estimated from satellite remote sensing and ancillary data in semi-arid Southeastern Turkey where traditionally dry agricultural lands are being rapidly transformed into irrigated fields with the help of water from the Euphrates-Tigris Rivers. An image classification methodology based on thresholding of Landsat NDVI images from the peak summer period reveals that the total area of summer irrigated crops has increased three-fold (from 35,000 ha to over 100,000) in the Harran Plain between 1993 and 2002. Coupled analysis of annual irrigated crop area from remote sensing and potential evapotranspiration based …

Applying Cognitive Psychology To Education, Training And Testing: Review Of Experimental Cognitive Psychology And Its Applications, A. F. Healy (Ed.)., Brian H. Bornstein

Department of Psychology: Faculty Publications

This book, which is part of the American Psychological Association’s Decade of Behavior series, is both less and more than it seems. Its title sounds like it would be suitable for a cognitive psychology laboratory course, but its scope is too narrow for that. It focuses largely on a relatively small subset of applied cognitive psychological topics—education, training, and testing—and the research traditions of three (albeit three distinguished and influential) researchers: Lyle Bourne, Walter Kintsch, and Thomas Landauer. In that sense, then, the book is less than it seems. In another sense, though, it is more than it seems. In …

Time-Series Analysis Of Clusters In City Size Distributions, Ahjond S. Garmestani, Craig R. Allen, K. Michael Bessey

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Complex systems, such as urban systems, emerge unpredictably without the influence of central control as a result of adaptive behavior by their component, interacting agents. This paper analyses city size distributions, by decade, from the south-western region of the United States for the years 1890–1990. It determines if the distributions were clustered and documents changes in the pattern of clusters over time. Clusters were determined utilizing a kernel density estimator and cluster analysis. The data were clustered as determined by both methods. The analyses identified 4–7 clusters of cities in each of the decades analysed. Cities cluster into size classes, …

Estimated Ultraviolet Radiation Doses In Wetlands In Six National Parks, Stephen A. Diamond, Peter C. Trenham, Michael J. Adams, Blake R. Hossack, Roland A. Knapp, Stacey L. Stark, David Bradford, P. Stephen Corn, Ken Czarnowski, Paul D. Brooks, Dan Fagre, Bob Breen, Naomi E. Detenbeck, Kathy Tonnessen

United States Geological Survey: Staff Publications

Ultraviolet-B radiation (UV-B, 280–320-nm wavelengths) doses were estimated for 1024 wetlands in six national parks: Acadia (Acadia), Glacier (Glacier), Great Smoky Mountains (Smoky), Olympic (Olympic), Rocky Mountain (Rocky), and Sequoia/ Kings Canyon (Sequoia). Estimates were made using ground-based UV-B data (Brewer spectrophotometers), solar radiation models, GIS tools, field characterization of vegetative features, and quantification of DOC concentration and spectral absorbance. UV-B dose estimates were made for the summer solstice, at a depth of 1 cm in each wetland. The mean dose across all wetlands and parks was 19.3 W-h m^-2 (range of 3.4–32.1 W-h m^-2). The mean …

Bats Of Jamaica, Hugh H. Genoways, John W. Bickham, Robert J. Baker, Carleton J. Phillips

University of Nebraska State Museum: Mammalogy Papers

The modern history of Jamaica is entwined with European exploration of the New World beginning with the landing of Columbus at Discovery Bay on May 4, 1494, during his second voyage to the Americas. Since that time the word Jamaica has conjured thoughts of tropical beaches, trade winds, pleasant tropical nights, Spaniards, British navy, Empire, sugar, rum, plantations, slavery, revolt, maroons, pirates, Port Royal, disasters, hurricanes, and in more recent years independence, tourism, Reggae, and welcoming and happy residents. Our knowledge of Jamaican natural history begins with Browne (1789). He and other early naturalists displayed a broad interest in plants …

The July 2003 Dakota Hailswaths: Creation, Characteristics, And Possible Impacts, Matthew D. Parker, Ian Ratcliffe, Geoffrey M. Henebry

School of Natural Resources: Faculty Publications

The authors investigate the meteorology associated with two elongated swaths of crop damage produced by severe hailstorms that crossed North Dakota and South Dakota on 4 July and 20 July 2003. These hailswaths, which were observed in a Moderate Resolution Imaging Spectroradiometer (MODIS) Normalized Difference Vegetation Index (NDVI) image time series, each persisted for more than a month and were associated with local temperature increases, presumably owing to the enhanced Bowen ratio over dry, crop-free ground. This paper documents the creation and evolution of the convective storms that produced the hailswaths, and then presents evidence that devegetated hailswaths may impact …

Information And Communication Technologies And The Effects Of Globalization: Twenty-First Century “Digital Slavery” For Developing Countries—Myth Or Reality?, L. A. Ogunsola

E-JASL: Electronic Journal of Academic and Special Librarianship (1999-2009, Volumes 1-10)

Abstract

The main goal of this paper is to examine the ICT (Information and Communication Technology) revolution and the concept of globalization as they effect developing countries. Globalization as one of the reasons for possible widening of the gap between the poor and the rich nations was examined and the emerging concept of “digital slavery” was carefully evaluated. The wide gap in availability and use of ICTs across the world and the influences ICTs exert on globalization at the expense of developing countries were carefully examined and suggestions and necessary policies were offered for developing countries to leap-frog the industrialization …

Biology, Habitat Preference, And Larval Description Of Cicindela Cursitans Leconte (Coleoptera: Carabidae: Cicindelinae), Mathew L. Brust, W. Wyatt Hoback, C. Barry Knisley

Department of Entomology: Faculty Publications

Cicindela cursitans LeConte is a small, flightless tiger beetle with a widely scattered distribution in the Great Plains, the Ohio Valley, and the north-central Gulf Coast region. Many aspects of the life history of C. cursitans are poorly known, and the larval stages have remained undescribed until now. We designed experiments to determine specific habitat preference, female oviposition preference, and daily activity cycles of the adults. In addition, we describe the entire pre-adult life history. Adults are most numerous on moist clay soils with sparse to patchy vegetation, but they may also occur in tall-grass prairies. Females oviposit strictly in …

Placement Of Riparian Forest Buffers To Improve Water Quality, Mark D. Tomer, Mike Dosskey, Michael R. Burkart, David E. James, Matthew J. Helmers, Dean E. Eisenhauer

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

Riparian forest buffers can improve stream water quality, provided they intercept and remove contaminants from surface runoff and/or shallow groundwater. Soils, topography, hydrology, and surficial geology determine the capability of forest buffers to intercept and treat these flows. This paper describes landscape analysis techniques for identifying and mapping locations where forest buffers can effectively improve water quality. One technique employs soil survey and climate information to rate soil map units for how effectively a buffer would treat runoff. Results can be used to compare map units for relative effectiveness of buffer installations to improve water quality and, accordingly, to prioritize …

Plant Adaptation Regions: Ecological And Climatic Classification Of Plant Materials, Kenneth P. Vogel, Marty R. Schmer, Robert B. Mitchell

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

The effective use of plant materials for an array of objectives including conservation, restoration, renovation, landscaping, and bioremediation requires knowledge of the adaptation of each species and, more specifically, knowledge of the adaptation of cultivars, strains, accessions, or ecotypes of a species to specific sites or regions. For agronomic and horticultural plants, specific adaptation information has been and continues to be developed by extensive testing. Rangeland, grassland, park, and restoration project managers often lack the resources to determine adaptation areas for plant materials because of the large number of species that are used and the extensive geographical areas that are …

Architecture Of The Wilderness: Understanding Culture And Ecology In The Sandhills Of Nebraska Through Design, Patrick J. Moore

The intent of this project is to create an interpretive center for a proposed regional tourism network in a rural Nebraska County. The design will be based on issues of sustainability, including resource conservation, socio-economic improvement, and environmental protection. Specific issues addressed include: Green Buildings, Biomimicry, Mechanical Systems, Construction Methods, Biology and Geology Research and Education, Regional Planning, and Vernacular Buildings. This project, explores how architecture can be used in a …

Are Political Orientations Genetically Transmitted?, John R. Alford, Carolyn L. Funk, John R. Hibbing

Department of Political Science: Faculty Publications

We test the possibility that political attitudes and behaviors are the result of both environmental and genetic factors. Employing standard methodological approaches in behavioral genetics—–specifically, comparisons of the differential correlations of the attitudes of monozygotic twins and dizygotic twins—–we analyze data drawn from a large sample of twins in the United States, supplemented with findings from twins in Australia. The results indicate that genetics plays an important role in shaping political attitudes and ideologies but a more modest role in forming party identification; as such, they call for finer distinctions in theorizing about the sources of political attitudes. We conclude …

Collaboration As A Foundation For The Project Approach In Family Child Care, Joan Youngquist, Carolyn P. Edwards, Ruth Heaton

Supporting children's curiosity was considered important at my family child care home. How could we best achieve this? As my assistant caregiver Deb and 1 attended professional development workshops, we began to wonder if the project approach (Helm & Katz 2001) would be an effective means of supporting inquiry and collaborative learning. Before we would commit ourselves, we wanted to learn more. We had many questions. Just what is the project approach? What does it look like? How will it support children's learning? What do we need to be successful with it? The literature suggested many examples of successful projects …

A Fishing Farm In The West Fjords Of Iceland: A Preliminary Report Of The Archaeofauna From Gjögur, Yekaterina Krivogorskaya, Sophia Perdikaris, Thomas H. Mcgovern

School of Global Integrative Studies: Faculty Publications

The date for the onset of full scale commercial fisheries in Iceland remains somewhat controversial, but thus far the earliest radiocarbon dated seasonal fishing station (11th- 13th century) is in NW Iceland’s Strandasýsla County at Akurvík. This paper presents a preliminary report of the ongoing analysis of the large archaeofauna from the farm mound at Gjögur, 3 km from Akurvík, places the site of Gjögur in the wider context of the NW region of Iceland by comparing the site with the Akurvík archaeofauna, and outlines new methodologies of reconstructing live fish size and age based on recovered fish bones. Although …

Readings In Place: Recent Publications In Southwestern Literature And Studies, Thomas Lynch

Department of English: Faculty Publications

The "Southwest" is nearly always defined along the intersection of two axes, one cultural and the other natural. Certain characteristics of these two axes are obvious in the six works considered here. Culturally, the region is most distinguished from the rest of the US by the existence of two enduring ethnic communities, the indigenous and the Hispanic, with the presence of the Mexican border exerting a powerful influence. In very different ways, Molly H. Mullin’s Culture in the Market Place: Gender, Art, and Value in the American Southwest, Audrey Goodman’s Translating Southwestern Landscapes: The Making of an Anglo Literary …
