Howard, George Elliott (1849-1928), Michael R. Hill

Department of Sociology: Faculty Publications

George Elliott Howard, a distinguished social scientist trained initially in history, rose to the presidency of the American Sociological Society in 1917. Howard earned the A.B. in 1876 at the University of Nebraska. Following two years of advanced study in Germany, Howard joined the Nebraska faculty in 1879. Howard's most prominent Nebraska student from this period, Amos Griswold Warner, later wrote American Charities (1894) - a standard classic in the field. Howard was named to the prestigious "First Faculty" of Stanford University in 1891.

Latitudinal And Longitudinal Adaptation Of Switchgrass Populations, Michael D. Casler, Kenneth P. Vogel, C. M. Taliaferro, N. J. Ehlke, J. D. Berdahl, E. C. Brummer, R. L. Kallenbach, C. P. West, R. B. Mitchell

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

Switchgrass (Panicum virgatum L.) is a warmseason native grass, used for livestock feed, bioenergy, soil and wildlife conservation, and prairie restoration in a large portion of the USA. The objective of this research was to quantify the relative importance of latitude and longitude for adaptation and agronomic performance of a diverse group of switchgrass populations. Six populations, chosen to represent remnant prairie populations on two north–south transects, were evaluated for agronomic traits at 12 locations ranging from 36 to 47°N latitude and 88 to 101°W longitude. Although the population × location interactions accounted for only 10 to 31% of …

Genetic Diversity, Plant Adaptation Regions, And Gene Pools For Switchgrass, Michael D. Casler, Chad A. Stendal, Ludmila Kapich, Kenneth P. Vogel

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

Switchgrass (Panicum virgatum L.) is a perennial grass native to the North American tallgrass prairie and broadly adapted to the central and eastern USA. Transfer of germplasm throughout this region creates the potential of contaminating local gene pools with genes that are not native to a locale. The objective of this study was to identify structural patterns and spatial variation for molecular markers of switchgrass populations from the northern and central USA. Forty six prairie-remnant populations and 11 cultivars were analyzed for random amplified polymorphic DNA (RAPD) markers. Although there was significant population differentiation, little of this variation was …

World Agriculture And Environment: A Commodity-By-Commodity Guide To Impacts And Practices [Book Review], Charles A. Francis

Department of Agronomy and Horticulture: Faculty Publications

This comprehensive reference book provides a good overview of global agriculture at the end of the millennium. In the introduction, author Jason Clay brings his long experience—in farming, teaching, and government service—into the presentation of a balanced perspective on how production must be balanced with concern for the environment. Now with World Wildlife Fund, he couples a background in economics, anthropology and geography with considerable professional experience in aquaculture and cooperation in the private sector to explore multiple aspects of agriculture and food production. He is particularly effective in discussing the economic and environmental sustainability of the food system, although …

The San Andreas Fault Observatory at Depth (SAFOD), drilled near the town of Parkfield, California (Fig. 1) (Hickmen et al., 2004) as part of the U.S. National Science Foundation's EarthScope Project (see http://www.earthscope.org), provieds a continuous set of samples through the active San Andreas Fault (SAF) zone. These samples can help address decades-old questions such as apparent weakness of the SAF (Zoback, 2000) providing the unparalleled opportunity to contrain the parameters that control the behavior of plate counding faults like the San Andreas.

Samples collected form SAFOD also complement studies of exhumed fault zones. While studies of exhumed fault zones …

Genomic Deletion Marking An Emerging Subclone Of Francisella Tularensis Subsp. Holarctica In France And The Iberian Peninsula, M. P. Dempsey, M. Dobson, C. Zhang, M. Zhang, C. Lion, C. B. Gutiérrez-Martín, P. C. Iwen, P. D. Fey, M. E. Olson, D. Niemeyer, S. Francesconi, R. Crawford, M. Stanley, J. Rhodes, D. M. Wagner, A. J. Vogler, D. Birdsell, P. Keim, A. Johansson, S. H. Hinrichs, A. K. Benson

Department of Food Science and Technology: Faculty Publications

Francisella tularensis subsp. holarctica is widely disseminated in North America and the boreal and temperate regions of the Eurasian continent. Comparative genomic analyses identified a 1.59-kb genomic deletion specific to F. tularensis subsp. holarctica isolates from Spain and France. Phylogenetic analysis of strains carrying this deletion by multiple-locus variable-number tandem repeat analysis showed that the strains comprise a highly related set of genotypes, implying that these strains were recently introduced or recently emerged by clonal expansion in France and the Iberian Peninsula.

Spectral Analysis Of Coastal Vegetation And Land Cover Using Aisa+ Hyperspectral Data, R. Jensen, P. Mausel, N. Dias, R. Gonser, C. Yang, J. Everitt, R. Fletcher

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

This paper describes a spectral analysis of several coastal land cover types in
South Padre Island, Texas using AISA₊ hyperspectral remote sensing data.
AISA₊ hyperspectral data (1.5 metre) were acquired throughout the area on 9
March 2005. Data over mangrove areas were converted to percent reflectance
using four 8 ×8 metre reflectance tarps (4%, 16%, 32% and 48%) and empirical
line calibration. These data were then compared to percent reflectance values of
other terrestrial features to determine the ability of AISA₊ data to distinguish
features in coastal environments. Results suggest that these data may be
appropriate to …

Grassland Establishment For Wildlife Conservation, D. Todd Jones-Farrand, Loren W. Burger Jr., Douglas H. Johnson, Mark R. Ryan

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Establishing grasslands has important implications for wildlife, especially in areas historically rich in grasslands that have since been converted to row crop agriculture. Most grasslands established under farm conservation programs have replaced annual crops with perennial cover that provides year-round resources for wildlife. This change in land use has had a huge influence on grassland bird populations; little is known about its impacts on other terrestrial wildlife species. Wildlife response to grassland establishment is a multi-scale phenomenon dependent upon vegetation structure and composition within the planting, practice-level factors such as size and shape of the field, and its landscape context, …

Late Cenozoic Climate Changes In China’S Western Interior: A Review Of Research On Lake Qinghai And Comparison With Other Records, Steven M. Colman, Shi-Yong Yua, Zhisheng Anc, Ji Shend, A.C.G. Henderson

United States Geological Survey: Staff Publications

We review Late Cenozoic climate and environment changes in the western interior of China with an emphasis on lacustrine records from Lake Qinghai. Widespread deposition of red clay in the marginal basins of the Tibetan Plateau indicates that the Asian monsoon system was initially established by ~8 Ma, when the plateau reached a threshold altitude. Subsequent strengthening of the winter monsoon, along with the establishment of the Northern Hemisphere ice sheets, reflects a long-term trend of global cooling. The few cores from the Tibetan Plateau that reach back a million years suggest that they record the mid-Pleistocene transition from glacial …

Dune Fields: Mid-Latitudes, J. Sun, Daniel R. Muhs

United States Geological Survey: Staff Publications

Large dune fields, or sand seas, are landscapes often thought to be found only in deserts beneath the great, subtropical high-pressure zones, where subsiding air suppresses rainfall. Dune fields are also quite common in mid-latitude regions, to the north and south of subtropical deserts (Fig. 1). Two major characteristics distinguish many mid-latitude dune fields from the sand seas of lower latitudes. One difference is that many of those in mid-latitudes are in semiarid, rather than arid climates, and therefore are not presently active. In this article, ‘active’ refers to eolian sand bodies that are not covered with vegetation, and where …

Conservation Genetics Of Snowy Plovers (Charadrius Alexandrinus) In The Western Hemisphere: Population Genetic Structure And Delineation Of Subspecies, W. Chris Funk, Thomas D. Mullins, Susan M. Haig

United States Geological Survey: Staff Publications

We examined the genetic structure of snowy plovers (Charadrius alexandrinus) in North America, the Caribbean, and the west coast of South America to quantify variation within and among breeding areas and to test the validity of three previously recognized subspecies. Sequences (676 bp) from domains I and II of the mitochondrial control region were analyzed for 166 snowy plovers from 20 breeding areas. Variation was also examined at 10 microsatellite loci for 144 snowy plovers from 14 breeding areas. The mtDNA and microsatellite data provided strong evidence that the Puerto Rican breeding group is genetically divergent from sites …

Territoriality, Prospecting, And Dispersal In Cooperatively Breeding Micronesian Kingfishers (Todiramphus Cinnamominus Reichenbachii), Dylan C. Kesler, Susan M. Haig

United States Geological Survey: Staff Publications

We investigated territoriality, prospecting, and dispersal behavior in cooperatively breeding Pohnpei Micronesian Kingfishers (Todiramphus cinnamominus reichenbachii) throughout the annual cycle using radiotelemetry and color-band resights. Mean home-range size was 6.3 ha and territories were 8.1 ha. Within territories, Micronesian Kingfishers shared 63% of their home-range space with coterritorial occupants, and 3% was shared with extraterritorial conspecifics. Birds on cooperative territories had larger home ranges that overlapped more with coterritory occupants’ home ranges than birds in pair-held territories. Despite evidence suggesting that resources necessary for survival and reproduction occurred on each territory, Micronesian Kingfishers of all age and sex …

Surface-Exposure Ages Of Front Range Moraines That May Have Formed During The Younger Dryas, 8.2 Cal Ka, And Little Ice Age Events, Larry Benson, Richard Madole, Peter Kubik, Richard Mcdonald

United States Geological Survey: Staff Publications

Surface-exposure (¹⁰Be) ages have been obtained on boulders from three post-Pinedale end-moraine complexes in the Front Range, Colorado. Boulder rounding appears related to the cirque-to-moraine transport distance at each site with subrounded boulders being typical of the 2-km-long Chicago Lakes Glacier, subangular boulders being typical of the 1-km-long Butler Gulch Glacier, and angular boulders being typical of the few-hundred-m-long Isabelle Glacier. Surface-exposure ages of angular boulders from the Isabelle Glacier moraine, which formed during the Little Ice Age (LIA) according to previous lichenometric dating, indicate cosmogenic inheritance values ranging from 0 to ~3.0 ¹⁰Be ka.¹ Subangular …

The Influence Of Refugee Status On Palestinian Identity And The Impact Of Identity On Durable Solutions To The Refugee Problem, Michaela S. Clemens

Nebraska Anthropologist

Over the last fifty years the Israeli-Palestinian conflict has generated massive numbers of refugees. The scale and longevity of the conflict has made the Palestinian refugee problem the most protracted and largest refugee situation in the world today (Merhab et al. 2006). The processes of becoming a refugee and living as a refugee have had direct impacts on the formation of Palestinian identity. In this paper, I examine the influence of refugee status on identity and discuss how this identity affects potential solutions to the protracted refugee situation. I offer a brief historical background to the creation of Palestinian refugees. …

Archaeology In Palestine: The Life And Death Of Albert Glock, Katherine Lamie

Nebraska Anthropologist

This paper provides a critical examination of the dynamic connection between archaeological research and programs of political and religious agendas in Israel and Palestine. This examination contributes to recent discipline-wide discussions concerning the powerful impact of archaeological research in areas of political and religious turmoil. The first section of this paper notes the absence of an Islamic counterpart to Biblical archaeology. While there is no archaeology that attempts to prove literal interpretations of the Qur'an, the rather complex archaeology advanced by Albert Glock (1984; 1994; 1995) serves to meet the needs of marginalized Palestinian villagers. Yet Glock's experience with the …

Native Land Acquisition In The Minnesota River Valley, Laura J. Smith

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

The economic issues that often arise from Native land acquisition and development can strain relationships between American Indian tribes and non-Indian local governments. As Indian tribes expand their landholdings, political and economic landscapes are transformed. This paper examines intergovernmental relationships and the characteristics and impacts of recent land acquisitions made by two Dakota Indian communities in the Minnesota River Valley of Minnesota. The Upper Sioux Community has enjoyed a level of cooperation from local communities in their rural land acquisitions, while the Shakopee Mdewakanton Dakota Community has experienced vigorous opposition to their urban land acquisitions. Geographic situation may help to …

The Shop-Locally Discourse In Jefferson County Kansas, Gina K. Thornburg

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

Inhabitants in the villages of Jefferson County, Kansas, respond to socioeconomic changes in a variety of ways. Empirical research conducted in 2004 revealed multiple discourses that constituted such responses. The shop-locally discourse emerged in structured interviews, newspaper articles, and newspaper advertisements as an emblem of socioeconomic empowerment. Discourse was analyzed within its context and interpreted to provide some insight into residents' responses to change. The discourse revealed not only nostalgia for formerly vibrant commercial districts but also the importance of economic vitality to social life. Shopping locally today, however, will not restore yesteryear's social milieu. The proximity of midsize cities …

Eastward Ho: Phylogeographical Perspectives On Colonization Of Hosts And Parasites Across The Beringian Nexus [Guest Editorial], Eric Waltari, Eric P. Hoberg, Enrique P. Lessa, Joseph A. Cook

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The response of Arctic organisms and their parasites to dramatic fluctuations in climate during the Pleistocene has direct implications for predicting the impact of current climate change in the North. An increasing number of phylogeographical studies in the Arctic have laid a framework for testing hypotheses concerning the impact of shifting environmental conditions on transcontinental movement. We review 35 phylogeographical studies of trans-Beringian terrestrial and freshwater taxa, both hosts and parasites, to identify generalized patterns regarding the number, direction and timing of trans-continental colonizations. We found that colonization across Beringia was primarily from Asia to North America, with many events …

Multiplication Of Ovaries In Ctenotaenia Marmotae (Frölich, 1802) (Cestoda: Anoplocephalidae), Sumiya Ganzorig, Yuzaburo Oku, Scott Lyell Gardner, Masao Kamiya

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Individuals of the cestode species Ctenotaenia marmotae (Frölich, 1802) (Cestoda: Anoplocephalidae) possessing duplicated rudimentary ovaries toward the medial parts of the segments were found in material collected from the Siberian marmot (Marmota sibirica) in Mongolia. This tapeworm is characterized by possessing one pair of female genitals per segment. The extra rudimentary ovaries that we found ranged from one to six in number per segment and were much smaller than the main pairs of ovaries. Although multiplication of ovaries was reported to occur in a species of Diandrya (Darrah, 1930) by Rausch (1980), this is the first report of …

An Improved Qc Process For Temperature In The Daily Cooperative Weather Observations, Kenneth Hubbard, Nathaniel B. Guttman, Jinsheng You, Zhirong Chen

Department of Earth and Atmospheric Sciences: Faculty Publications

TempVal is a spatial component of data quality assurance algorithms applied by the National Climatic Data Center (NCDC), and it has been used operationally for about 4 yr. A spatial regression test (SRT) approach was developed at the regional climate centers for climate data quality assurance and was found to be superior to currently used quality control (QC) procedures for the daily maximum and minimum air temperature. The performance of the spatial quality assessment procedures has been evaluated by assessing the rate with which seeded errors are identified. A complete dataset with seeded errors for the year 2003 for the …

Dinosaur Tectonics: A Structural Analysis Of Theropod Undertracks With A Reconstruction Of Theropod Walking Dynamics, Ole Graversen, Jesper Milán, David B. Loope

Department of Earth and Atmospheric Sciences: Faculty Publications

A dinosaur trackway in the Middle Jurassic eolian Entrada Sandstone of southern Utah, U.S.A., exposes three undertracks that we have modeled as isolated tectonic regimes showing the development of fold-thrust ramp systems induced by the dinosaur’s feet. The faulted and folded sequence is comparable to crustal-scale tectonics associated with plate tectonics and foreland fold-thrust belts. A structural analysis of the dinosaur tracks shows the timing and direction of the forces exercised on the substrate by the animal’s foot during the stride. Based on the structural analysis, we establish a scenario for foot movements and weight distribution in the feet. During …

Metadata: The Key To The Preservation And Dissemination Of Spatial Data, Adonna Fleming

University of Nebraska-Lincoln Libraries: Faculty Publications

The preservation and dissemination of digital research data has become a hot topic among the university research co mmunity. Of particular concern is the availability of GIS spatial data. Often the biggest roadblock to making GIS data available is that the creator of the project either does not have the time or the skills to create the metadata, a crucial component to making spatial data retrievable from GIS data portals. This paper describes how the University of Nebraska-Lincoln Libraries (UNL Libraries), as part of its GIS program, has stepped in to help its campus community develop and distribute FGDC/ISO compliant …

The first goal of this study (RQ1) was to describe how the people of Norse, Texas experience ethnicity. The second goal of this study (RQ2) was to discover how this ethnicity was communicatively constructed and maintained. The third goal of this study (RQ3) was to learn how the relationship between ethnic identity and communication contributes to the creation of shared meanings within the community. The fourth goal (RQ4) of this study was to describe the …

Writing The Nation: Ignacio Manuel Altamirano's Romantic Vision And Porfirian Development, Jason C. Denzin

Department of History: Dissertations, Theses, and Student Research

As articulated in Ignacio Manuel Altamirano’s Romantic novel El Zarco (1888) and the accounts of contemporary travelers, various interpretations about the pace and course of the country’s development abounded in Mexico during the late nineteenth-century. The current project evaluates El Zarco as a historical text and uses it as a window into the Porfirian nation-building project. By comparing the vision outlined in the novel with the published accounts of contemporary travelers this project demonstrates the contested nature of development among Mexico’s national elites during the Porfiriato. This thesis argues that from the competing visions of national development specific categories for …

Department of Entomology: Faculty Publications

The sex pheromone of the scarab beetle, Phyllophaga anxia, is a blend of the methyl esters of two amino acids, L-valine and L-isoleucine. A field trapping study was conducted, deploying different blends of the two compounds at 59 locations in the United States and Canada. More than 57,000 males of 61 Phyllophaga species (Coleoptera: Scarabaeidae: Melolonthinae) were captured and identified. Three major findings included: (1) widespread use of the two compounds [of the 147 Phyllophaga (sensu stricto) species found in the United States and Canada, males of nearly 40% were captured]; (2) in most species intraspecific male …
