Proactive Environmental Strategies: Managing A Corporate Culture Shift Toward Sustainability, Mark E. Calub Dec 2015

Proactive Environmental Strategies: Managing A Corporate Culture Shift Toward Sustainability, Mark E. Calub

Master's Projects and Capstones

The roles and responsibilities of Environmental, Health and Safety (EHS) professionals have expanded over the last several decades. Initially focused solely on reducing a firm's ecological impact, many EHS professionals are now tasked with managing a firm's cultural shift towards sustainability. EHS professionals need to develop proactive environmental strategies that further interconnect the environmental, social, and economic performance goals of the firm. Using a concept analysis and integrative literature review approach, the research examines the evolving role of corporate environmental management and evaluates strategic management tools for environmental compliance, environmental performance, and corporate sustainability. The research reveals that the role …


Genetic Analysis Of The Henry Mountains Bison Herd, Dustin H. Ranglack, Lauren K. Dobson, Johan T. Du Toit, James Derr Dec 2015

Genetic Analysis Of The Henry Mountains Bison Herd, Dustin H. Ranglack, Lauren K. Dobson, Johan T. Du Toit, James Derr

Wildland Resources Faculty Publications

Wild American plains bison (Bison bison) populations virtually disappeared in the late 1800s, with some remnant animals retained in what would become Yellowstone National Park and on private ranches. Some of these private bison were intentionally crossbred with cattle for commercial purposes. This forced hybridization resulted in both mitochondrial and nuclear introgression of cattle genes into some of the extant bison genome. As the private populations grew, excess animals, along with their history of cattle genetics, provided founders for newly established public bison populations. Of the US public bison herds, only those in Yellowstone and Wind Cave National Parks (YNP …

U.S. Vehicle Efficiency Standards, Derek Baylog Dec 2015

U.S. Vehicle Efficiency Standards, Derek Baylog

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

The United States is a driving force of the global economy and a major innovator in the technology sector. For decades the world has looked to The United States as a leader of great technological advancements with the strong economy to allow investors a chance make these technologies a reality. So why is it now that we lag behind other countries when it comes to making our technology energy efficient? Sure we’ve been steadily growing our production of renewable resources with wind and solar energy, bet we are still behind in the second largest source of pollution, transportation. According to …


When Addressing Climate Change, Don’T Forget Animal Agriculture, Aaron Matzke Dec 2015

When Addressing Climate Change, Don’T Forget Animal Agriculture, Aaron Matzke

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

As COP 21 closes in Paris, global animal agriculture is a topic that has eluded the international media. Animal agriculture is responsible for more global greenhouse gas emissions than transportation according to the U.N.’s Food and Agriculture Organization. With global population and prosperity rising, the global meat supply is expected to nearly double by 2050. This increase in production will only be achieved if significant steps are taken to promote sustainability through existing techniques globally, and to regulate air contamination in industrial feedlots in the United States. Alternative meat production methods, which have seen considerable investment recently, could supplement animal …


Energy Subsidies And The Future Of Power, Christian Jewett Dec 2015

Energy Subsidies And The Future Of Power, Christian Jewett

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

The modern political climate has grown rife with talk concerning the use of fossil fuels as an energy source and how this may impact our planet for generations to come. The Left and the Right seem to be at odds over whether or not climate change is actually occurring, or who is causing it. Additionally, the energy industry likes to tout their “low-cost” energy sources as a boon to the global economy as well as a benefit to the consumer at large. However, are coal, oil, and natural gas truly the “cheapest” sources of energy? Whether or not one believes …


Making Walkable Communities, Katie Zuehlke Dec 2015

Making Walkable Communities, Katie Zuehlke

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

There is no doubt that global warming is happening. With all the rage about climate change and global warming people should be doing more about it than just reading about it in the news. We should be making efforts towards making changes on a local level. This in turn could grow to a national level with more and more people participating in the movement and actually make global changes, instead of just talking about it. When the scale of participants grows the scale of the changes made will grow as well and this will be the beginning of the changes …


Incentives Critical To Full Wind Power Potential In Nebraska, Michael Neale Dec 2015

Incentives Critical To Full Wind Power Potential In Nebraska, Michael Neale

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

On August 3rd, President Obama and the EPA announced the Clean Power Plan (CPP) with the goal of cutting 32% of carbon emissions nationwide by 2030. The plan institutes carbon reduction requirements for all states based on their current sources of energy, for Nebraska the goal is 40%. The next day, Governor Ricketts and his Attorney General announced they would be fighting the mandate in court; stating the plan is unlawful federal government overreach, while expressing concerns the reduction are infeasible in the timeframe given and will drive up electricity costs. Governor Ricketts misses the point on this. Reducing carbon …


Longevity Of Mineral Supplements Within The Soil And Associated Use By White-Tailed Deer, Brian C. Peterson, Keith D. Koupal, Andrew K. Schissel, Cody M. Siegel Dec 2015

Longevity Of Mineral Supplements Within The Soil And Associated Use By White-Tailed Deer, Brian C. Peterson, Keith D. Koupal, Andrew K. Schissel, Cody M. Siegel

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Humans have baited wildlife such as white-tailed deer (Odocoileus virginianus) for generations with the primary purpose of increasing hunting harvest success. Baiting regulation changes are often considered by state management agencies as they pertain to hunting opportunity, fair chase, and disease risk. Cervids require a variety of minerals to supplement biological processes, especially sodium (Na), calcium (Ca), and phosphorus (P). We developed artificial mineral supplement sites set in front of trail cameras to monitor deer use. Pooled soil samples were collected at mineral sites and compared to the surrounding area to determine the longevity of elevated minerals levels …


Three-Dimensional Wind Speed And Flux Measurements Over A Rain-Fed Soybean Field Using Orthogonal And Non-Orthogonal Sonic Anemometer Designs, Taylor Thomas Dec 2015

Three-Dimensional Wind Speed And Flux Measurements Over A Rain-Fed Soybean Field Using Orthogonal And Non-Orthogonal Sonic Anemometer Designs, Taylor Thomas

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

The eddy covariance method for estimating fluxes of trace gases, energy and momentum in the constant flux layer above a plant canopy fundamentally relies on accurate measurements of the vertical wind speed. This wind speed is typically measured using a three-dimensional ultrasonic anemometer. Previous studies comparing anemometers with orthogonal transducer sets to those with non-orthogonal transducer sets suggest differences in measured 3D wind speed components, particularly for a vertical component. These differences, attributed to additional flow distortion caused by the non-orthogonal transducer arrangement and support structure, directly affect fluxes of trace gases, energy and momentum. A field experiment was conducted …


Geographic Variation, Null Hypotheses, And Subspecies Limits In The California Gnatcatcher: A Response To Mccormack And Maley, Robert M. Zink, Jeffrey G. Groth, Hernan Vázquez-Miranda Dec 2015

Geographic Variation, Null Hypotheses, And Subspecies Limits In The California Gnatcatcher: A Response To Mccormack And Maley, Robert M. Zink, Jeffrey G. Groth, Hernan Vázquez-Miranda

School of Natural Resources: Faculty Publications

We interpreted the results of nuclear DNA sequencing to be inconsistent with the recognition of California Gnatcatcher (Polioptila californica) subspecies. McCormack and Maley (2015) suggested that our data did support 2 taxa, one of which was P. c. californica, listed as Threatened under the Endangered Species Act (ESA). We summarize here how 2 sets of researchers with access to the same data reached different conclusions by including different analyses. We included the southern subspecies’ boundary from the taxonomy of Atwood (1991), the taxonomic basis for the ESA listing, which resulted in an Analysis of Molecular Variance that …


The First Bromeligenous Species Of Dendropsophus (Anura: Hylidae) From Brazil's Atlantic Forest, Rodrigo Barbosa Ferreira, Julián Faivovich, Karen H. Beard, José P. Pombal Jr Dec 2015

The First Bromeligenous Species Of Dendropsophus (Anura: Hylidae) From Brazil's Atlantic Forest, Rodrigo Barbosa Ferreira, Julián Faivovich, Karen H. Beard, José P. Pombal Jr

Wildland Resources Faculty Publications

We describe a new treefrog species of Dendropsophus collected on rocky outcrops in the Brazilian Atlantic Forest. Ecologically, the new species can be distinguished from all known congeners by having a larval phase associated with rainwater accumulated in bromeliad phytotelms instead of temporary or lentic water bodies. Phylogenetic analysis based on molecular data confirms that the new species is a member of Dendropsophus; our analysis does not assign it to any recognized species group in the genus. Morphologically, based on comparison with the 96 known congeners, the new species is diagnosed by its small size, framed dorsal color pattern, and …


The Clean Power Plan Needs To Be A Law, Mitchell Frischmeyer Dec 2015

The Clean Power Plan Needs To Be A Law, Mitchell Frischmeyer

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

The Clean Power Plan (CPP) is a long overdue policy which is necessary to direct national investment in emerging markets and create an intelligent energy infrastructure that strives to operate at max efficiency. To this point, the US has developed using inefficient and dirty fuels, a method which allowed for cheap and reliable energy generation, but is largely responsible for the change in global climate. If we expect to prevent climate change, our energy infrastructure must be reformed. Countries like Denmark have led the way in energy reform by creating policies set to reach 100% renewable generation by 2050 (8). …


Olfactory Enrichment In California Sea Lions (Zalophus Californianus), Mystera M. Samuelson Dec 2015

Olfactory Enrichment In California Sea Lions (Zalophus Californianus), Mystera M. Samuelson

Dissertations

In the wild, California sea lions (Zalophus californianus) are exposed to a wide array of sensory information at all times. However, it is impossible for captive environments to provide this level of complexity. Therefore unique procedures and practices are necessary for the maintenance of physiological and psychological health in captive animals (Wells, 2009). This project aims to explore the behavioral effect of scent added to the environment, with the goal of improving the welfare of captive sea lions by introducing two scent types: 1.) Natural scents, found in their native environment, and 2.) Non-natural scents, not found in …


Climate Change And Interpersonal Violence: A "Global" Estimate And Regional Inequities, Dennis Mares, Kenneth W. Moffett Nov 2015

Climate Change And Interpersonal Violence: A "Global" Estimate And Regional Inequities, Dennis Mares, Kenneth W. Moffett

SIUE Faculty Research, Scholarship, and Creative Activity

This study estimates the predicted impact of climate change on levels of violence in a sample of 57 countries. We sample western and non-western countries and perform a multilevel ARFIMA regression to examine if warmer temperatures are associated with higher levels of homicide. Our results indicate that each degree Celsius increase in annual temperatures is associated with a nearly 6% average increase in homicides. Regional variation in this predicted effect is detected, for example, with no apparent effects in former Soviet countries and far stronger effects found in Africa. This variation indicates that climate change may acutely increase violence in …

A High-Resolution Paleoenvironmental And Paleoclimatic History Of Extreme Events On The Laminated Sediment Record From Basin Pond, Fayette, Maine, U.S.A., Daniel R. Miller Nov 2015

A High-Resolution Paleoenvironmental And Paleoclimatic History Of Extreme Events On The Laminated Sediment Record From Basin Pond, Fayette, Maine, U.S.A., Daniel R. Miller

Masters Theses

Future impacts from climate change can be better understood by placing modern climate trends into perspective through extension of the short instrumental records of climate variability. This is especially true for extreme climatic events, such as extreme precipitation and wildfires, as the period of instrumental records provides only a few examples and these have likely have been influenced by anthropogenic warming. Multi-parameter records showing the past range of climate variability can be obtained from lakes. Lakes are particularly good recorders of climate variability because sediment from the surrounding environment accumulates in lakes, making them sensitive recorders of climate variability and …

Assessing Kiln-Produced Hardwood Biochar For Improving Soil Health In A Temperate Climate Agricultural Soil, Emily J. Cole Nov 2015

Assessing Kiln-Produced Hardwood Biochar For Improving Soil Health In A Temperate Climate Agricultural Soil, Emily J. Cole

Doctoral Dissertations

Soil quality has become a major factor used in assessing sustainable land management and the overall environmental quality, food security, and economic viability of agricultural lands. Recently, biochar has been touted as having many potential uses as a soil amendment for improving soil quality, specifically improving cation exchange capacity, pH and nutrient availability. However, soil biology also plays a significant role in biogeochemical processes that influence soil health and should be included in a more comprehensive study of soil health. This dissertation describes 4 projects within the same 3-year field study with the cumulative purpose of better understanding the effect …

Department of Earth and Atmospheric Sciences: Faculty Publications

The rocky and indented coast of NW Iberia is characterized by the presence of highly valuable and vulnerable, small and shallow barrier– lagoon systems structurally controlled. The case study was selected to analyse barrier–lagoon evolution based on detailed sedimentary architecture, chronology, geochemical and biological proxies. The main objective is to test the hypothesis of structural control and the significance at regional scale of any highenergy event recorded. This work is also aimed at identifying general patterns and conceptualizing the formation and evolution of this type of coastal systems. The results allowed us to establish a conceptual model of Holocene evolution …

The Vulnerability Of Indo-Pacific Mangrove Forests To Sea-Level Rise, Catherine E. Lovelock, Donald R. Cahoon, Daniel A. Friess, Glenn R. Guntenspergen, Ken W. Krauss, Ruth Reef, Kerrylee Rogers, Megan L. Saunders, Frida Sidik, Andrew Swales, Neil Saintilan, Le Xuan Thuyen, Tran Triet

United States Geological Survey: Staff Publications

Sea-level rise can threaten the long-term sustainability of coastal communities and valuable ecosystems such as coral reefs, salt marshes and mangroves1,2. Mangrove forests have the capacity to keep pace with sea-level rise and to avoid inundation through vertical accretion of sediments, which allows them to maintain wetland soil elevations suitable for plant growth3. The Indo- Pacific region holds most of the world’s mangrove forests4, but sediment delivery in this region is declining, owing to anthropogenic activities such as damming of rivers5. This decline is of particular concern because the Indo-Pacific region is …

Cars And Karst: Investigating The National Corvette Museum Sinkhole, Jason S. Polk, Leslie North, Ric Federico, Brian Ham, Dan Nedvidek, Kegan Mcclanahan, Pat Kambesis, Mike Marasa

Sinkhole Conference 2015

On February 12th, 2014, a sinkhole occurred at the National Corvette Museum in Bowling Green, Kentucky. The collapse happened inside part of the building known as the Skydome and eight Corvettes on display were lost into the void that opened in the concrete floor. In this region of Kentucky, known as the Pennyroyal sinkhole plain, subsidence and cover collapse sinkholes are commonly found throughout the landscape. This iconic karst region in the United States is also home to Mammoth Cave, the longest cave in the world, and thousands of other caves and karst features. Investigation of the sinkhole collapse began …
