Vegetation Monitoring At Homestead National Monument Of America, Nebraska, 1998–2017, Sherry A. Leis

United States National Park Service: Publications

Executive Summary

The Heartland Inventory and Monitoring Network has sampled permanent monitoring sites in three vegetation community types (restored prairie, successional forest, and bur oak forest) at Homestead National Monument of America since 1998 (includes nine sample years). Network scientists record each species, aerial cover estimates of ground flora, diameter at breast height of midstory and overstory trees, and tree regeneration frequency (tree seedlings and saplings) within these permanent sites.

The park has experienced similar periods of drought and wetness through the monitoring record. Ground cover estimates indicate that prairie litter and bare ground are negatively related; prescribed fire cycles …

Wyandot, Shawnee, And African American Resistance To Slavery In Ohio And Kansas, Diane Miller

Department of History: Dissertations, Theses, and Student Research

From the colonial period, enslaved Africans escaped bondage. Colonial records and treaties reveal that they often sought refuge with Indian tribes. This resistance to slavery through escape and flight constituted the Underground Railroad. As European colonies developed into the United States, alliances of subaltern groups posed a threat. Colonizers and settlers aimed to divide and control these groups and arrived at the intertwined public policies of African chattel slavery and Indian removal. Tribal abolitionism and participation in the Underground Railroad was more pronounced than scholars have recognized and constituted an important challenge to the expansion of slavery.

Drought Impacts Assessment In Brazil: A Remote Sensing Approach, Denis Mariano

School of Natural Resources: Dissertations, Theses, and Student Research

Climate extremes are becoming more frequent in Brazil; studies project an increase in drought occurrences in many regions of the country. In the south, drought events lead to crop yield losses affecting the value chain and, therefore, the local economy. In the northeast, extended periods of drought lead to potential land degradation, affecting the livelihood and hindering local development. In the southern Amazon, an area that experienced intense land use change (LUC) in the last, the impacts are even more complex, ranging from crop yield loss and forest resilience loss, affecting ecosystem health and putting a threat on the native …

Developing A Framework To Link Multi-Sector Drought Impacts To Drought Severity At The State Level, Mary Noel

School of Natural Resources: Dissertations, Theses, and Student Research

The United States Drought Monitor, a weekly map depicting severity and spatial extent of drought, is a key indicator for federal and state policy decisions including the annual distribution of hundreds of millions of dollars for agricultural financial relief in the United States. However, the current table describing potential drought impacts for the map’s severity levels fails to adequately represent a state’s unique environmental, economic, and social values affected by drought. One approach to improve this broad, national-scale assessment is to transition from the former platform to a more detailed characterization of drought impacts at the state level. To accomplish …

A Multi-Sensor Phenotyping System: Applications On Wheat Height Estimation And Soybean Trait Early Prediction, Wenan Yuan

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

Phenotyping is an essential aspect for plant breeding research since it is the foundation of the plant selection process. Traditional plant phenotyping methods such as measuring and recording plant traits manually can be inefficient, laborious and prone to error. With the help of modern sensing technologies, high-throughput field phenotyping is becoming popular recently due to its ability of sensing various crop traits non-destructively with high efficiency. A multi-sensor phenotyping system equipped with red-green-blue (RGB) cameras, radiometers, ultrasonic sensors, spectrometers, a global positioning system (GPS) receiver, a pyranometer, a temperature and relative humidity probe and a light detection and ranging (LiDAR) …

Search For Resonant Double Higgs Production With Bbzz Decays In The Bbℓℓνν Final State In Pp Collisions At √S = 13 Tev, Rami Kamalieddin

Department of Physics and Astronomy: Dissertations, Theses, and Student Research

Since the discovery of the Higgs boson in 2012 by the ATLAS and CMS experiments, most of the quantum mechanical properties that describe the long-awaited Higgs boson have been measured. Due to the outstanding work of the LHC, over a hundred of fb⁻¹ of proton collisions data have been delivered to both experiments. Finally, it became sensible for analyses teams to start working with a very low cross section processes involving the Higgs boson, e.g., a recent success in observing ttH and VHbb processes. One of the main remaining untouched topics is a double Higgs boson production. However, an …

Indigenous Data Governance: Strategies From United States Native Nations, Stephanie Russo Carroll, Desi Rodriguez-Lonebear, Andrew Martinez

Copyright, Fair Use, Scholarly Communication, etc.

Data have become the new global currency, and a powerful force in making decisions and wielding power. As the world engages with open data, big data reuse, and data linkage, what do data-driven futures look like for communities plagued by data inequities? Indigenous data stakeholders and non-Indigenous allies have explored this question over the last three years in a series of meetings through the Research Data Alliance (RDA). Drawing on RDA and other gatherings, and a systematic scan of literature and practice, we consider possible answers to this question in the context of Indigenous peoples vis-á-vis two emerging concepts: Indigenous …

Comparing Nebraskan And Finnish Education Policy And Its Impacts On Mathematics Teaching, Elizabeth Tyler

Honors Program: Senior Projects (Public)

For two decades, Finland has been in the education spotlight as they consistently receive high international exam scores while spending less money, less time teaching, and putting students through fewer hours of school. This study aims to investigate the related policy that may help explain these seemingly paradoxical findings in the education sector. More specifically, this study examines how related policy impacts math teachers in their day to day work. This research includes an extensive literature review that explores several facets of the education system in both Nebraska and Finland in order to better understand existing policies. This background is …

Nationalism And Education: A Case Study Of Germany And Japan, Sarah Vrtiska

Honors Program: Senior Projects (Public)

In this piece I ask the question: How has education contributed to the formation or prevention of nationalism in Germany and Japan? In examining this, after defining the standard conceptions of nationalism, I apply these definitions to pre-war and post-war Germany and Japan. Ultimately, I conclude that the goals of education, concepts of national identity that are taught, history curricula, and control of education all historically have the potential to contribute to the rise of nationalism within a country. Based on these fields, I find that although there are similar nationalist trends in both countries during the pre-war period, in …

The Paradoxical Implications Of Deported American Students, Edmund T. Hamann, Jessica Mitchell-Mccollough

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

This book chapter (which has no formal abstract) uses the case of two children who had to leave the United States because their father was deported to raise questions about how US schooling does or does not anticipate and support students who will need to negotiate schooling in two countries.

Principals and teachers throughout the United States (and world) have students with transnational ties. Sometimes students were born in another country. More commonly, one or both parents were. Sometimes that means students and/or parents lack documentation, which creates anxiety and ambiguity in students’ lives that schools need to negotiate. Suro …

Estimating Offsets For Avian Displacement Effects Of Anthropogenic Impacts, Jiill A. Shaffer, Charles R. Loesch, Deborah A. Buhl

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

Biodiversity offsetting, or compensatory mitigation, is increasingly being used in temperate grassland ecosystems to compensate for unavoidable environmental damage from anthropogenic developments such as transportation infrastructure, urbanization, and energy development. Pursuit of energy independence in the United States will expand domestic energy production. Concurrent with this increased growth is increased disruption to wildlife habitats, including avian displacement from suitable breeding habitat. Recent studies at energy-extraction and energy-generation facilities have provided evidence for behavioral avoidance and thus reduced use of habitat by breeding waterfowl and grassland birds in the vicinity of energy infrastructure. To quantify and compensate for this loss in …

Drought Impacts And Management In Prairie And Sandhills State Parks, Theresa M. Jedd, Devarati Bhattacharya, Cara Pesek, Michael J. Hayes

School of Natural Resources: Faculty Publications

The combination of decreased water availability and increased temperatures can interfere with outdoor activities, particularly with surface water decline and the increased risk of wildfire. Drought is a longer-term climate trend, but there is a tendency toward short-term reactions only when a drought occurs. Policy mechanisms for drought, where present, are often left to managerial discretion because they are not needed every year, and lack specific indicators. Recreator choices contribute to adaptation and public lands managers also shape drought response by monitoring meteorological trends and managing resources wisely. Despite these trends, no singular recreational drought definition exists. To understand socio-environmental …

Assessing The Impact Of Game Day Schedule And Opponents On Travel Patterns And Route Choice Using Big Data Analytics, Anuj Sharma, Vesal Ahsani

Nebraska Department of Transportation: Research Reports

The transportation system is crucial for transferring people and goods from point A to point B. However, its reliability can be decreased by unanticipated congestion resulting from planned special events. For example, sporting events collect large crowds of people at specific venues on game days and disrupt normal traffic patterns.

The goal of this study was to understand issues related to road traffic management during major sporting events by using widely available INRIX data to compare travel patterns and behaviors on game days against those on normal days. A comprehensive analysis was conducted on the impact of all Nebraska Cornhuskers …

Stantial, Chelsea E. Weithman, Daniel H. Catlin

School of Natural Resources: Faculty Publications

The inverse relationship between body size and environmental temperature is a widespread ecogeographic pattern. However, the underlying forces that produce this pattern are unclear in many taxa. Expectations are particularly unclear for migratory species, as individuals may escape environmental extremes and reorient themselves along the environmental gradient. In addition, some aspects of body size are largely fixed while others are environmentally flexible and may vary seasonally. Here, we used a long-term dataset that tracked multiple populations of the migratory piping plover Charadrius melodus across their breeding and non-breeding ranges to investigate ecogeographic patterns of phenotypically flexible (body mass) and fixed …

Seduction, Promises And Disneyfication Of Barbuda Post Irma, Sophia Perdikaris, Rebecca Boger, Emira Ibrahimpašić

School of Global Integrative Studies: Faculty Publications

Under the guise of post-hurricane development, the national government of Antigua and Barbuda exploited the disasterscape of post Hurricane Irma Barbuda to usher in a new wave of economic development that has left Barbudans separated from their unique culture and identity. In this article we explore what are inhabited vs. uninhabited spaces, the effects of Colonial Christian ideas on cultivated vs. uncultivated lands and the effects of capitalist seduction to traditional landscapes and seascapes. We argue that this neocolonial approach to traditional lifeways increases vulnerability of both people and environment. By wiping out diversity and culture in order to replace …

Review Of Birds Of Prey Of The West: A Field Guide, By Brian K. Wheeler, Daniel Casey

The Prairie Naturalist

Birds of prey epitomize much of what attracts us to birding. Many are large and easy to observe, particularly in open landscapes. Their predatory nature and behavior give them an added aura of wildness; their migrations can be spectacular. And even veteran birders should enjoy the challenge of identifying the myriad of plumage variations shown by different ages, sexes, subspecies, and color morphs. With his newest effort, Birds of Prey of the West, Brian Wheeler has compiled a comprehensive and enhanced field guide with illustrations that stunningly capture that variation, combined with enough additional context to make it a valuable …

Seventh Grade Students' Understanding Of A Groundwater Modeling Tool, Holly White

Department of Environmental Studies: Undergraduate Student Theses

Water is a core topic in standards for science teaching and learning across the K-12 continuum (NGSS Lead States, 2013; National Research Council [NRC], 1966), though research has shown that the American public may possess relatively underdeveloped ideas about water systems (AMNH, 2005). Those who have a better understanding of groundwater systems tend to recognize the impacts that overuse has and express greater concern about conservation of the resource (Pan and Liu 2018). One way to support students’ learning about groundwater is through the use of groundwater modeling tools. Computer-based models have been shown to be effective in supporting K-12 …

Sustainable Dietary Solutions To A Multi-Dimensional Epidemic: A Practical Application Of The Mediterranean Diet To Nebraska, Samuel A. Virgillito

Department of Environmental Studies: Undergraduate Student Theses

There is substantial evidence to suggest the major health and environmental benefits of the Mediterranean diet. When compared to the Western Pattern diet, the Mediterranean diet consistently ranks higher by both of these measures. Considering a looming environmental crisis and an already present health epidemic, a major dietary shift and overhaul of the current food system in America is necessary. Yet few studies aim to suggest the transferability of the Mediterranean diet to regions outside of the Mediterranean basin. Nebraska offers a unique case study as it reflects the contextually poor health of Americans and boasts a massive agriculture industry …

Nitrate Contamination And Nitrogen Isotope Compositions In The Bazile Groundwater Management Area: A Water Quality Study. Creighton, Ne, Sydney Corcoran

Department of Environmental Studies: Undergraduate Student Theses

Surface water nitrogen contamination is a pervasive issue in Nebraska, and agricultural practices are the main source of nitrogen input to streams (Spalding and Exner, 1993). Nitrate can come from inorganic fertilizers such as anhydrous ammonia, or animal waste. Studies have been conducted on nitrates dating back to 1947 (Addleman, 1985). The Bazile Groundwater Management Area (BGMA) located in northeast Nebraska has historically had high nitrate contamination. This qualitative study assesses the seasonal sources of nitrogen to stream water. It is predicted that the source of input is from commercial synthetic fertilizers. By using nitrogen- oxygen isotope methods, the source …
