This research was conducted in various towns of eastern and central Nebraska using a survey which asked respondents about how valuable the resources and ecological benefits are that were to be involved in the construction of the Keystone XL pipeline. Surveys were administered in public locations using a combination of convenience and snowball sampling. A total of 38 respondents from the eastern region and 40 from the central region were surveyed. The research seeks to investigate if there is correlation between certain demographic categories and high value placed on the environmental facets in question. Do males or females place higher …

Warming Nighttime Temperatures And Crop Health In The Corn Belt, Justin Hladik

Department of Environmental Studies: Undergraduate Student Theses

Over the last century nighttime minimum temperatures have been increasing at a faster rate than daily maximum temperatures. This warming trend has caught the attention of climatologists and agricultural scientists as they attempt to address the potential effects of elevated nighttime minimum temperatures on the health of these crops, which are so important to the U.S. economy. In this study, ten sites represent the Corn Belt of the United States. Those sites are spread across an area in which the average minimum nighttime temperatures for each of the three primary growing months of the year (June, July, August) increased from …

Resource Distribution And The French Revolution, Louan Pagan

Department of Environmental Studies: Undergraduate Student Theses

Throughout the centuries following the French Revolution (1789 -1799), social scientists and historians have attributed a myriad of causes to the sociopolitical upheaval. Food and beverages played a key role in the coming of French Revolution, for the people were in effect fighting for the right to have nutrition rather than for social or political ideals. Literary analysis of both primary and secondary sources illustrated the integral role of the peasant’s stomach to the uprising. The Enlightenment disillusionment of the royals, rising bread prices, discrepancy in food distribution both within and around Paris, and substandard quality of food, wine, and …

Universities are an important part of the global community, and it is pertinent that they become more involved in sustainable efforts. University research laboratories produce large amounts of regular and hazardous waste, use massive amounts of energy, and are currently not operating in sustainable ways. The purpose of this study is to determine the …

A Comparison Of Moist-Soil Seed Sampling Techniques In The Nebraska Rainwater Basin, Lisa Zilli

Department of Environmental Studies: Undergraduate Student Theses

Wetland managers sometimes estimate seed production of wetlands managed for migrating waterfowl habitat. Using estimation techniques, managers can determine if wetland plants produce enough seed to support the nutritional needs of migrating waterfowl. Usually, a one-time sampling method is used; this technique samples seeds once a year during peak seed production. However, this technique may underestimate seed production due to plants producing large quantities of seed before or after peak seed production or producing seed throughout the growing season. Season long sampling may be more representative of a wetland’s seed production. We comparing one-time sampling with season- long sampling by …

Continued growth in the craft brewing industry, coupled with natural resource limitations suggests the need for implementation of sustainable initiatives on a wide scale. These initiatives discussed include the areas of economic sustainability through cooperative growth and equilibrium, social sustainability through employee and community development, and environmental sustainability through energy and water conservation and renewable energy use. Specific techniques to achieve sustainability in the craft brewing industry are reviewed alongside case studies of craft breweries currently implementing these techniques. A sustainable metric is outlined for use in accomplishing these goals.

Predicting Lemna Minor Growth Rate Response To Temperature Fluctuations, Elizabeth Novich

Department of Environmental Studies: Undergraduate Student Theses

The effects of global climate change on populations may be further understood when environmental variability is included. There are strong theoretical reasons that support the idea that environmental fluctuations matter when studying ecological systems. In order to further explore this, we parameterized a model of the growth rate of Lemna minor at constant temperatures and made predictions on how L. minor would respond to fluctuating temperatures based on this model. There were four trials performed that compared the difference between growth rates at constant and fluctuating temperatures in order to test if our predictions were correct. For our results, only …

The Role Of Emotion In Understanding And Promoting Sustainability And Eco-Friendly Behavior, Chevelle Schreiner

Department of Environmental Studies: Undergraduate Student Theses

Research has demonstrated the effectiveness of empathy and perspective-taking in influencing

environmental concern (Sevilliano, Aragones, & Schultz, 2007) Although there may be a number of internal factors that inhibit pro-environmental behavior, it is important to evaluate the ways by which we can use emotion to encourage this type of behavior. This study was designed to evaluate the impact of emotion on eco-friendly behavior by investigating the effect of viewing high- or low-fear appeals on changing consumers‘ food choices will have on their attitudes and behaviors. Results show that the

likelihood that a participant intended to partake in more pro-environmental behaviors …

Using Landsat Imagery To Monitor Post-Fire Vegetation Recovery In The Sandhills Of Nebraska: A Multitemporal Approach, James Mcbride

Department of Environmental Studies: Undergraduate Student Theses

The objective of this study was to look at a wildfire in the Nebraska Sandhills as a case study for multi-temporal monitoring of burned areas using Landsat-7 satellite images. Eight Landsat-7 scenes were selected and a shapefile of the perimeter of a September 2000 wildfire in the Fort Niobrara National Wildlife Refuge. A true color composite, color infrared composite, and a single-band NDVI output was used for visual analysis. A subset of burned and unburned sections was taken from the NDVI images; the values were graphed and compared. The visual analysis of the true color and color infrared images show …

Do Tree Species In A Bornean Mixed Dipterocarp Forest Display Preferential Uptake Of Different Nitrogen Forms?, Jocelyn Onley

Department of Environmental Studies: Undergraduate Student Theses

Lambir Hills National Park in Malaysian Borneo is composed of dipterocarp tree species which specialize on different soil types. Although the mechanisms contributing to this distribution of tree species are unknown, one hypothesis is that tree species at Lambir differ in their preferences for different nitrogen forms. In this study we investigated (1) whether clay soil and sandy loam soil types at Lambir differ in the availability of ammonium and nitrate and (2) whether tree species specializing on either clay soil or sandy loam soil at Lambir have differing preferences or capacities to take up ammonium, nitrate, or glycine (organic …

Transportation Network Analysis For Bicycle Suitability In Lincoln Nebraska Using Geographic Information Systems (Gis), Andrew J. Pedley

Department of Environmental Studies: Undergraduate Student Theses

With increasing fuel costs, concern over global climate change, and increasing obesity levels, cycling is being promoted as a healthy sustainable alternative to automobile transportation. In order to improve a city’s transportation network to accommodate cyclists, an assessment of the current system is needed. This project uses the Bicycle Compatibility Index (BCI) to rate the bikeability of streets in a subarea of Lincoln, Nebraska. In this study I assessed the feasibility of using the BCI rating method on a city-wide level and list suggestions to improve the method. The information created in this project can be used by planning officials …

Prevalence Of Childhood Obesity In Elementary Schools In Lincoln, Nebraska: A Study Of Children On Free Or Reduced Lunches, Eric Barth

Department of Environmental Studies: Undergraduate Student Theses

The purpose of the project is to show that there is a direct relationship between childhood obesity and socioeconomic status. Other factors that go into this relationship include: physical activity and foods available in vending machines. My ultimate objective is to prove that children coming from low socioeconomic backgrounds are showing higher levels of obesity during childhood. I believe that this work, as well as other studies similar to this, can be used show that these children need more help and assistance. Many of these children are not taught proper eating habits; generally because cheaper foods are generally not nutrition …

West Of Eden: Resource Wars And Nature-Cultures In The American West, Scout Calvert

University of Nebraska-Lincoln Libraries: Faculty Publications

The richness and variety of the western landscape is what is at stake in hot political contests for the resources of the West: much of this public land is available to economic activity, including for mining, grazing, logging, and recreation. These uses threaten to outpace the land’s ability to renew these resources along with others, like air and water. Now in the first decade of the millennium with a new environmental awareness emerging partly from media coverage of global warming and peak oil, The American West at Risk offers a wide-ranging look at the degradation of the environment in the …

Scotts Bluff National Monument, Plant Community Resource Brief, Isabel Ashton, Mike Prowatzke

United States National Park Service: Publications

2011 Monitoring Status

Overview

In 2011, the first year of vegetation monitoring by the Northern Great Plains Network Inventory and Monitoring staff at Scotts Bluff National Monument, efforts resulted in the documentation of 79 plant species. This was the lowest number of species among parks sampled in 2011. Graminoid (grass and grass-like plant) species accounted for only 21 (27%) of the total species, but graminoid cover was much higher than that of any other plant type. Forbs were much more diverse, but did not provide as much foliar cover.

The 5 most abundant native non-graminoids were winterfat (Krascheninnikovia lanata …

Plant community composition and structure monitoring comprises the core of the vegetation monitoring effort for the NGPN, covering the “Riparian Lowland Plant Communities” and “Upland Plant Communities” vital signs (Gitzen et al. 2010). The narrative portion of the plant community protocol can be found in Symstad et al. 2012. The narrative includes the rationale for vegetation monitoring, an overview of sample design, field methods, data management, and program requirements. This document contains the standard operating procedures …

On Evapotranspiration And Shallow Groundwater Fluctuations: A Fourier-Based Improvement To The White Method, Mehmet Evren Soylu, John D. Lenters, Erkan Istanbulluoglu, Steven P. Loheide Ii

School of Natural Resources: Faculty Publications

Evapotranspiration (ET) is a significant component of the water and energy balance in wetlands and riparian zones, yet it is also one of the most challenging components to estimate. Diurnal water table fluctuations can be used to directly measure groundwater consumption by phreatophytes, which are often important contributors to the total ET in riparian systems. Although such methods are cost effective, significant uncertainties usually exist, and more accurate techniques continue to be developed. In this study we present a new ‘‘Fourier method’’ for calculating daily (and longer) groundwater ET consumption using a moving, multiday sine function to capture robust, diurnal …

Spatial Heterogeneity Across Five Rangelands Managed With Pyric-Herbivory, Devan Allen Mcgranahan, David M. Engle, Samuel D. Fuhlendorf, Stephen L. Winter, James R. Miller, Diane M. Debinski

School of Natural Resources: Faculty Publications

1. Many rangelands evolved under an interactive disturbance regime in which grazers respond to the spatial pattern of fire and create a patchy, heterogeneous landscape. Spatially heterogeneous fire and grazing create heterogeneity in vegetation structure at the landscape level (patch contrast) and increase rangeland biodiversity. We analyzed five experiments comparing spatially heterogeneous fire treatments to spatially homogeneous fire treatments on grazed rangeland along a precipitation gradient in the North American Great Plains.

2. We predicted that, across the precipitation gradient, management for heterogeneity increases both patch contrast and variance in the composition of plant functional groups. Furthermore, we predicted that …

Positive Pollutions And Cultural Toxins, John Blair Gamber

University of Nebraska Press: Sample Books and Chapters

In this innovative study, Positive Pollutions and Cultural Toxins, John Blair Gamber examines urbanity and the results of urban living—traffic, garbage, sewage, waste, and pollution—arguing for a new recognition of all forms of human detritus as part of the natural world and thus for a broadening of our understanding of environmental literature. While much of the discourse surrounding the United States’ idealistic and nostalgic views of itself privileges “clean” living (primarily in rural, small-town, and suburban settings), representations of rurality and urbanity by Chicanas/Chicanos, African Americans, Asian Americans, and Native Americans, on the other hand, complicate such generalization. Gamber …

Engaging The Humanities To Address Wildland Fire Issues, Fred Swanson, Nathaniel Brodie, Charles Goodrich

Joint Fire Science Program Research Project Reports

This project examined existing programs and potential options for collaborations among the humanities, art, science, land management, and public concerning wildfire and wildfire policy and education. These programs and partnerships include creative residencies; conferences, workshops, and symposia; art-science collaborative field studies; and community programs and partnerships. We also reviewed how popular literature frames, reflects and has affected our cultural understanding of wildfire. Our analysis concludes that, compared to the richness of the subject of wildfire, compared to the way wildfire encapsulates all the complexities and controversies of culture, history, and ecology, wildfire’s potential as a literary subject remains largely unfulfilled. …

Covariation Between Understorey Light Environments And Soil Resources In Bornean Mixed Dipterocarp Rain Forest, Sabrina E. Russo, Lin Zhang, Sylvester Tan

School of Biological Sciences: Faculty Publications

Variation in understorey irradiance is both a cause and consequence of the structure and dynamics of closed-canopy forests, which are also influenced by soil nutrients and water availability. We tested the hypothesis that understorey light regimes differ among four mixed dipterocarp forest types that share the same rainfall, but grow on different soils along an edaphic gradient at one site in Borneo. Based on data from photosynthetically active radiation sensors deployed at 1-m height at 36 locations for 351 sensor-days, we found significant soil-related variation in irradiance. The more productive forest types on clay and fine loam had lower daily …
