Horses were domesticated from the Eurasian steppes 5,000–6,000 years ago. Since then, the use of horses for transportation, warfare, and agriculture, as well as selection for desired traits and fitness, has resulted in diverse populations distributed across the world, many of which have become or are in the process of becoming formally organized into closed, breeding populations (breeds). This report describes the use of a genome-wide set of autosomal SNPs and 814 horses from 36 breeds to provide the first detailed description of equine breed diversity. F_ST calculations, parsimony, and distance analysis demonstrated relationships among the breeds that largely …

Department of Earth and Atmospheric Sciences: Faculty Publications

This is the first part of a three-part paper on North American climate in phase 5 of the Coupled Model Intercomparison Project (CMIP5) that evaluates the historical simulations of continental and regional climatology with a focus on a core set of 17models. The authors evaluate the models for a set of basic surface climate and hydrological variables and their extremes for the continent. This is supplemented by evaluations for selected regional climate processes relevant to North American climate, including cool season western Atlantic cyclones, the North American monsoon, the U.S. Great Plains low-level jet, and Arctic sea ice. In general, …

The Mid-Domain Effect: It’S Not Just About Space, Andrew D. Letten, S. Kathleen Lyons, Angela T. Moles

School of Biological Sciences: Faculty Publications

Ecologists and biogeographers have long sought to understand how and why diversity varies across space. Up until the late 20th century, the dominant role of environmental gradients and historical processes in driving geographical species richness patterns went largely undisputed. However, almost 20 years ago, Colwell & Hurtt (1994) proposed a radical reappraisal of ecological gradient theory that called into question decades of empirical and theoretical research. That controversial idea was later termed the ‘the mid-domain effect’: the simple proposition that in the absence of environmental gradients, the random placement of species ranges within a bounded domain will give rise to …

Different Modes Of Evolution In Males And Females Generate Dichromatism In Fairy-Wrens (Maluridae), Allison E. Johnson, J. Jordan Price, Stephen Pruett-Jones

School of Biological Sciences: Faculty Publications

Sexual dichromatism in birds is often attributed to selection for elaboration in males. However, evolutionary changes in either sex can result in plumage differences between them, and such changes can result in either gains or losses of dimorphism. We reconstructed the evolution of plumage colors in both males and females of species in Maluridae, a family comprising the fairy-wrens (Malurus, Clytomias, Sipodotus), emu-wrens (Stipiturus), and grasswrens (Amytornis). Our results show that, across species, males and females differ in their patterns of color evolution. Male plumage has diverged at relatively steady rates, whereas …

Large-Scale Spatial Synchrony And Cross-Synchrony In Acorn Production By Two California Oaks, Walter D. Koenig, Johannes M.H. Knops

School of Biological Sciences: Faculty Publications

Seed production that varies greatly from year to year, known as ‘‘masting’’ or ‘‘mast-fruiting’’ behavior, is a population-level phenomenon known to exhibit geographic synchrony extending, at least in some cases, hundreds of kilometers. The two main nonexclusive hypotheses for the driver of such geographically extensive synchrony are (1) environmental factors (the Moran effect), and (2) the mutual dependence of trees on outcrossed pollen (pollen coupling). We tested 10 predictions relevant to these two hypotheses using 18 years of acorn production data on two species of California oaks. Data were obtained across the entire ranges of the two species at 12 …

Transferability Of Jarvis-Type Models Developed And Re-Parameterized For Maize To Estimate Stomatal Resistance Of Soybean: Analyses On Model Calibration, Validation, Performance, Sensitivity, And Elasticity, Denis Mutiibwa, Suat Irmak

Department of Agricultural and Biological Systems Engineering: Faculty Publications

In a previous study by the same authors, a new modified Jarvis model (NMJ-model) was developed, calibrated, and validated to estimate stomatal resistance (rs) for maize canopy on an hourly time step. The NMJ-model’s unique subfunctions, different from the original Jarvis model (J-model), include a photosynthetic photon flux density

(PPFD)-r_s response subfunction developed from field measurements and a new physical term, Aexp(1/LAI), where A is the minimum stomatal resistance and LAI is the green leaf area index, to account for the influence of canopy development on r_s, especially during partial canopy stage in the early season and …

Avhrr-Ndvi-Based Crop Coefficients For Analyzing Long-Term Trends In Evapotranspiration In Relation To Changing Climate In The U.S. High Plains, Denis Mutiibwa, Suat Irmak

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Studies in regions of extensive irrigation practices have revealed a significant influence of evaporative cooling on regional temperatures as a result of surface energy redistribution during evaporation. In the U.S. High Plains, maximum temperatures during the last quarter of the 20th century have been decreasing. We investigated the trends in evapotranspiration (ET or latent heat) fluxes originating from increasing irrigation practices in the High Plains region from 1981 to 2008. We estimated actual ET (ETc) over the entire High Plains from the spatial crop coefficients (Kc) and spatial reference (potential) ET (ETref). We proposed …

Organization Of Schooling In Three Countries, Edmund T. Hamann, Saloshna Vandeyar, Juan Sanchez Garcia

Department of Teaching, Learning, and Teacher Education: Faculty Publications

It has been more than 30 years since Britan and Cohen (1980) assembled a number of leading anthropologists in a joint call for an anthropology of bureaucracies. Their call was a refinement and rearticulation of a more enduring concern in anthropology, illustrated in particular in the work of South Africa-born, British anthropologist Meyer Fortes (1938) who was interested in what McDermott and Raley (2011: 46) have summarized as "the acquisition of kinds of people by social structure."

One starting point for an anthropology of organizations that sees schools as a particular kind of organization meriting direct scrutiny is the anthropology …

Review Of Nikkei In The Interior West: Japanese Immigrants And Community Building, 1882–1945 By Eric Walz, Jonathan Dresner

Great Plains Quarterly (through 2013)

Studies of Japanese immigration into North America generally focus on the larger Hawaiian and West Coast populations, but there is a small body of work on other areas, including New York, Texas, and the Canadian heartland. The core of Eric Walz’s book is a pioneering sourcerich examination of Japanese immigration and settlement experiences in the American West, including Nebraska, but excluding the coastal states and Midwest. As long as its focus stays on these sparsely distributed migrants, the book is an interesting addition to the literature, though not a final word. The decision to include Japanese historical and cultural context …

Review Of Re-Dressing America’S Frontier Past. By Peter Boag., William Benemann

Great Plains Quarterly (through 2013)

Long-established notions about life on the frontier are upended in this well-researched and finely written study of gender presentation, as the author maintains that cross-dressing was “very much a part of daily life on the frontier West.” Peter Boag recognizes the diversity and complexity of this issue, and one of the book’s strengths is that he seeks no simple answer to questions of why some women dressed as men, and some men dressed as women. Most readers will be familiar with the “progress narrative”—the story of women who passed as men in order to seek gainful employment, to serve their …

Review Of Sight Unseen: How Frémont’S Expedition Changed The American Landscape By Andrew Menard., Ryan Boyd

Great Plains Quarterly (through 2013)

Sight Unseen, Andrew Menard’s crisply written, deliciously illustrated, deeply sourced, and somewhat repetitive new book, contends that America has always been both an imaginative space where aesthetics, politics, and culture mingle, and the congeries of material environments to which those discourses respond. The text’s central figure, Captain John C. Frémont, evidently thought the same, and this conviction fueled an optimism that was rare at the time. In retrospect, the Louisiana Purchase was a good deal. But in 1842, when Frémont set out to survey the area between eastern Kansas and southern Wyoming, much of the territory we now call …

Review Of Life’S Journey—Zuya: Oral Teachings From Rosebud By Albert White Hat Sr. Compiled And Edited By John Cunningham, Tink Tinker

Great Plains Quarterly (through 2013)

Old-style, mainline anthropologists will probably not like this book. It is certainly not old-style anthropology. It is much, much more important than that. That White Hat fails to cite any of the pertinent literature on Lakotas is much beside the point; indeed, he indicates clearly that he does not much care for all of that literature as a means for finding meaning in Lakota life. White Hat is Siċangú Lakota and writes from deep within the Siċangú Lakota traditional knowledge. That is the importance of this book. Others have also written from within the Lakota world, even interpreters or so-called …

Geospatial Virtual Heritage: A Gesture-Based 3d Gis To Engage The Public With Ancient Maya Archaeology, Heather Richards-Rissetto, Jim Robertsson, Jennifer Von Schwerin, Giorgio Agugario, Fabio Remondino, Gabrio Girardi

Department of Anthropology: Faculty Publications

This paper presents our research to develop a gesture-based 3D GIS system to engage the public in cultural heritage. It compares two types of interaction—device-based vs. natural interaction— and summarizes the beta-testing results of a 3D GIS tool for archaeology, called QueryArch3D, in which participants used device-based interaction (i.e. mouse and keyboard). It follows with a description of the gesture-based system—that we developed in response to these beta-tests. The system uses QueryArch3D and Microsoft’s Kinect to enable people use body movements (in lieu of keyboard or mouse) to navigate a virtual reality landscape, query 3D objects, and call up photos, …

Chemostratigraphy Of The Early Pliocene Diatomite Interval From Mis And-1b Core (Antarctica): Paleoenvironment Implications, Giovanna Scopelliti, Adriana Bellanca, Donata Monien, Gerhard Kuhn

ANDRILL Research and Publications

The AND-1B drill core (1285 m-long) was recovered, inside the ANDRILL (ANtarctic geological DRILLing) Program, during the austral summer of 2006/07 from beneath the floating McMurdo Ice Shelf. Drilling recovered a stratigraphic succession of alternating diamictites, diatomites and volcaniclastic sediments spanning about the last 14 Ma. A core portion between 350 and 480 mbsf, including a 80 m-thick diatomite interval recording the early Pliocene warming event, was investigated in term of opal biogenic content and element geochemistry. Across the diatomite interval, in spite of the lithological uniformity, a fluctuating biogenic opal profile mirrors the δ18O record, testifying a decrease in …

Dog Burials Associated With Human Burials In The West Indies During The Early Pre-Columbian Ceramic Age (500 Bc-600 Ad), Sandrine Grouard, Sophia Perdikaris, Karyne Debue

School of Global Integrative Studies: Faculty Publications

Across the Caribbean, the widespread presence of canine remains at archaeological sites from the Saladoid period raises questions about the role of “man’s best friend.” Dog (Canis familiaris) remains have been found located in both refuse middens and burials adjacent to human graves in a number of sites in the French Antilles and Barbuda, West Indies. This paper will critically examine dog remains and discuss the varied duality of the dog’s role in the Saladoid world: from food source to lifelong companion. The importance of dogs within Amerindian sites from Saint Martin, the Guadeloupe archipelago, Martinique and Barbuda …

Colonoware And Culture: The Changing Interpretation Of 17th Century Ceramic Traditions In The South Eastern United States: An Overview Of Current Thought And History, Michael Chodoronek

Nebraska Anthropologist

Colonoware is a low fired pottery tradition concentrated in the southeastern United States. It has been associated with native populations, enslaved populations and low- income populations in the American colonies of the seventeenth through to the nineteenth century. This paper is concerned with the history, development and current conceptions of colonoware in the southeastern United States, namely Virginia and South Carolina coastal regions. This paper will look at the possible future use of colonoware as diagnostic material culture beyond its current state.

Invited Review: Sustainability Of The Us Dairy Industry, M. A. G. Von Keyserlingk, N. P. Martin, E. Kebreab, K. F. Knowlton, R.J. Grant, M. Stephenson Ii, C.J. Sniffen, J.P. Harner Iii, A.D. Wright, S.I. Smith

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

The US dairy industry has realized tremendous improvements in efficiencies and milk production since the 1940s. During this time, farm and total cow numbers have decreased and average herd size has increased. This intensification, combined with the shift to a largely urban public, has resulted in increased scrutiny of the dairy industry by social and environmental movements and increased concern regarding the dairy industry’s sustainability. In response to these concerns, a group of scientists specializing in animal welfare, nutrient management, greenhouse gas emissions, animal science, agronomy, agricultural engineering, microbiology, and economics undertook a critical review of the US dairy industry. …

Remote Sensing Of Fuel Moisture Content From Ratios Of Narrow-Band Vegetation Water And Dry-Matter Indices, Lingli Wang, E. Raymond Hunt Jr, John J. Qu, Xianjun Hao, Craig S.T. Daughtry

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

Fuel moisture content (FMC) is an important variable for predicting the occurrence and spread of wildfire. Because FMC is calculated from the ratio of canopy water content to dry-matter content, we hypothesized that FMC may be estimated by remote sensing with a ratio of a vegetation water index to a vegetation dry-matter index. Four vegetation water indices, six dry-matter indices, and the resulting water/dry-matter index ratios were calculated using simulated leaf reflectances from the PROSPECT model. Two water indices, the Normalized Difference Infrared Index (NDII) and the Normalized Difference Water Index (NDWI), were more correlated with leaf water content than …

Plant Community Composition And Structure Monitoring For Agate Fossil Beds National Monument, 2012 Annual Report, Isabel W. Ashton, Stephen K. Wilson, Daniel J. Swanson, Michael Prowatzke, Phil Graeve

United States National Park Service: Publications

Executive Summary

Agate Fossil Beds National Monument (AGFO) plays a vital role in protecting and managing some of the last remnants of native mixed-grass prairie in the region. The Northern Great Plains Inventory & Monitoring Network (NGPN) and Fire Ecology Program (FireEP) surveyed 12 long-term monitoring plots in Agate Fossil Beds National Monument in 2012 as part of an effort to better understand the condition of plant communities in the park. We measured plant diversity and cover, looked for the presence of exotic species that may be newly invading the park, and evaluated the amount of human and natural disturbance …

Survival And Behavior Of Chinese Mystery Snails (Bellamya Chinensis) In Response To Simulated Water Body Drawdowns And Extended Air Exposure, Kody M. Unstad, Daniel R. Uden, Craig R. Allen, Noelle M. Chaine, Danielle M. Haak, Robert A. Kill, Kevin L. Pope, Bruce J. Stephen, Alec Wong

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Nonnative invasive mollusks degrade aquatic ecosystems and induce economic losses worldwide. Extended air exposure through water body drawdown is one management action used for control. In North America, the Chinese mystery snail (Bellamya chinensis) is an invasive aquatic snail with an expanding range, but eradication methods for this species are not well documented. We assessed the ability of B. chinensis to survive different durations of air exposure, and observed behavioral responses prior to, during, and following desiccation events. Individual B. chinensis specimens survived air exposure in a laboratory setting for > 9 weeks, and survivorship was greater among adults …

Can Law Foster Social-Ecological Resilience?, Ahjond S. Garmestani, Craig R. Allen, Melinda H. Benson

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Law plays an essential role in shaping natural resource and environmental policy, but unfortunately, many environmental laws were developed around the prevailing scientific understanding that there was a “balance of nature” that could be managed and sustained. This view assumes that natural resource managers have the capacity to predict the behavior of ecological systems, know what its important functional components are, and successfully predict the outcome of management interventions. This paper takes on this problem by summarizing and synthesizing the contributions to this Special Feature (Law and Social-Ecological Resilience, Part I: Contributions from Resilience 2011), focusing on the interaction of …

Social-Ecological Predictors Of Global Invasions And Extinctions, Aaron Lotz, Craig R. Allen

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Most assessments of resilience have been focused on local conditions. Studies focused on the relationship between humanity and environmental degradation are rare, and are rarely comprehensive. We investigated multiple social-ecological factors for 100 countries around the globe in relation to the percentage of invasions and extinctions within each country. These 100 countries contain approximately 87% of the world’s population, produce 43% of the world’s per capita gross domestic product (GDP), and take up 74% of the earth’s total land area. We used an information theoretic approach to determine which models were most supported by our data, utilizing an a priori …

United States Environmental Protection Agency: Publications

The State of California has mandated the preparation of a guidance document on the application of fecal source identification methods for recreational water quality management. California contains the fifth highest population of cattle in the United States, making the inclusion of cow-associated methods a logical choice. Because the performance of these methods has been shown to change based on geography and/or local animal feeding practices, laboratory comparisons are needed to determine which assays are best suited for implementation. We describe the performance characterization of two end-point PCR assays (CF128 and CF193) and five real-time quantitative PCR (qPCR) assays (Rum2Bac, BacR, …

Environment Aware Connectivity For Wireless Underground Sensor Networks, Xin Dong, Mehmet C. Vuran

School of Computing: Conference and Workshop Papers

Wireless underground sensor networks (WUSNs) consist of sensors that are buried in and communicate through soil. The channel quality of WUSNs is strongly impacted by environmental parameters such soil moisture. Thus, the communication range of the nodes and the network connectivity vary over time. To address the challenges in underground communication, above ground nodes are deployed to maintain connectivity. In this paper, the connectivity of WUSNs under varying environmental conditions is captured by modeling the cluster size distribution under sub-critical conditions and through a novel aboveground communication coverage model for underground clusters. The resulting connectivity model is utilized to analyze …

A Historical Geography Of Sand Island 1870–1944, Lucas P. Johnson

Department of Geography: Dissertations, Theses, and Student Research

This thesis examines the settlement of Sand Island, one of two permanent colonies included within Lake Superior’s Apostle Islands archipelago. Following the introduction and literature review, a summary of Sand Island’s geology, climate and biological features is presented, serving to construct a baseline upon which to build a discussion of the island’s communal life. This foundation gives context to the seventy-four year struggle faced by the predominantly Norwegian immigrants adapting to that environment. It also serves to assist future scholars in studying wilderness recovery after what today is nearly an eighty year absence of the farmer’s plow. Chapter Four includes …
