An Investigation Into Factors Influencing Attitude Toward A Wildlife Corridor, Erin Kubicek 2016 University of Nebraska-Lincoln

An Investigation Into Factors Influencing Attitude Toward A Wildlife Corridor, Erin Kubicek

Dissertations & Theses in Natural Resources

Habitat fragmentation poses a serious threat to biodiversity in eastern Nebraska. Today, over 98% of Nebraska’s tall-grass prairie has been lost and what remains exists mostly as remnants less than 80 acres in size. The Prairie Corridor on Haines Branch will be one of the first human-made wildlife corridors in eastern Nebraska with expansion of prairie habitat as one of its main goals. Although still in the planning stages, the Prairie Corridor is a rare opportunity to explore public attitude toward a conservation-related program prior to its official launch. The purpose of this study is to explore the potential ...

Impact Of 4r Management On Crop Production And Nitrate-Nitrogen Loss In Tile Drainage, Matthew Helmers, John Sawyer, Josh Sievers

John E. Sawyer

Corn Belt corn and soybean producers are increasingly challenged to maximize crop production while addressing the contributions farm practices make to Gulf hypoxia. Based on the need for nitrate-N reductions to meet water quality goals, new management practices are needed to reduce nitrate-N losses at minimal cost and maximum economic benefits. This three-year field research and demonstration project is evaluating various promising N management methods and technologies by documenting the nitrate-N export and crop yield from various systems.


Implications Of Manipulations Of Soil Quality On The Growth Of European Buckthorn (Rhamnus Cathartica) In A Greenhouse, Sam L. Pepper, Liam Heneghan 2016 DePaul University

Implications Of Manipulations Of Soil Quality On The Growth Of European Buckthorn (Rhamnus Cathartica) In A Greenhouse, Sam L. Pepper, Liam Heneghan

DePaul Discoveries

European buckthorn (Rhamnus cathartica L.) is an invasive shrub that is capable of changing the nitrogen content of a soil through the deposition of its nitrogen rich leaf litter. This change creates conditions that may favor recolonizing by buckthorn and negatively affect the growth of native plants. In this greenhouse experiment, we examined the effect of altering soil quality by adding mulch comprised of buckthorn wood on above and belowground biomass, stem length and leaf production of buckthorn saplings. We found that buckthorn saplings planted in buckthorn mulch had reduced stem length and leaf production compared to growth in control ...

Kevin Hallinan

Energy use data for the eight-year period 2003–2010 was analyzed for over 1200 single family residences in Village of Yellow Springs, Ohio. Electricity, natural gas, residential building, and weather databases are merged to permit determination of the energy intensity of each home in the village. The energy use intensity for each home is disaggregated into weather independent and weather dependent electric and natural gas use. This use is compared to typical baseline, cooling, and heating energy use for the region. From this comparison, priority homes are identified for energy reduction investment. Collective potential low cost energy reduction is estimated ...

Prioritizing Investment In Residential Energy Efficiency And Renewable Energy: A Case Study For The U.S. Midwest, Robert J. Brecha, Austin Mitchell, Kevin P. Hallinan, J. Kelly Kissock

Kevin Hallinan

Residential building energy use is an important contributor to greenhouse gas emissions and in the United States represents about 20% of total energy consumption. A number of previous macro-scale studies of residential energy consumption and energy-efficiency improvements are mainly concerned with national or international aggregate potential savings. In this paper we look into the details of how a collection of specific homes in one region might reduce energy consumption and carbon emissions, with particular attention given to some practical limits to what can be achieved by upgrading the existing residential building stock. Using a simple model of residential, single-family home ...


Cost-Availability Curves For Hierarchical Implementation Of Residential Energy-Efficiency Measures, Roman Villoria-Siegert, Philip Brodrick, Kevin P. Hallinan, Robert J. Brecha 2016 University of Dayton

Cost-Availability Curves For Hierarchical Implementation Of Residential Energy-Efficiency Measures, Roman Villoria-Siegert, Philip Brodrick, Kevin P. Hallinan, Robert J. Brecha

Kevin Hallinan

Historical residential electricity data and natural gas consumption data were collected for, respectively, 1,200 and 178 residences in a small town in the USA. These data were merged with local building and weather databases, and energy consumption models were developed for each residence, revealing substantial variation in heating and cooling intensity. After estimating approximate physical building characteristics, energy profiles for each residence were calculated, and savings from adoption of the most cost-effective energy-efficiency measures for each residence were estimated. Effectively, we wish to leverage commonly available data sets to infer characteristics of building envelopes and equipment, without the need ...


Developing A Sustainable Water Supply In The American West: The Case Of Rio Rancho, New Mexico, Hubert B. Stroud, Mary K. Kilmer 2016 Arkansas State University-Main Campus

Developing A Sustainable Water Supply In The American West: The Case Of Rio Rancho, New Mexico, Hubert B. Stroud, Mary K. Kilmer

Suburban Sustainability

Suburban and urban communities in the American West are challenged by rapid population growth combined with limited natural resources. Supporting sustainable development is of great concern in this region and in similar regions throughout the world. This research examines the sustainability of the water supply within a rapidly growing suburban city in the American West. The city, Rio Rancho, New Mexico, began as an interstate land sales operation and rapidly became a “boom” town, in part because of its location near metropolitan Albuquerque.

Because of a very limited water supply and an increasing demand for water associated with population growth ...

Agenda: Coping With Water Scarcity In River Basins Worldwide: Lessons Learned From Shared Experiences, University Of Colorado Boulder. Getches-Wilkinson Center For Natural Resources, Energy, And The Environment

Coping with Water Scarcity in River Basins Worldwide: Lessons Learned from Shared Experiences (Martz Summer Conference, June 9-10)

Water scarcity is increasingly dominating headlines throughout the world. In the southwestern USA, the looming water shortages on the Colorado River system and the unprecedented drought in California are garnering the greatest attention. Similar stories of scarcity and crisis can be found across the globe, suggesting an opportunity for sharing lessons and innovations. For example, the Colorado River and Australia's Murray-Darling Basin likely can share many lessons, as both systems were over-allocated, feature multiple jurisdictions, face similar climatic risks and drought stresses, and struggle to balance human demands with environmental needs. In this conference we cast our net broadly ...

Agenda: Indigenous Water Justice Symposium, University Of Colorado Boulder. Getches-Wilkinson Center For Natural Resources, Energy, And The Environment

Indigenous Water Justice Symposium (June 6)

Indigenous peoples throughout the world face diverse and often formidable challenges of what might be termed “water justice.” On one hand, these challenges involve issues of distributional justice that concern Indigenous communities’ relative abilities to access and use water for self-determined purposes. On the other hand, issues of procedural justice are frequently associated with water allocation and management, encompassing fundamental matters like representation within governance entities and participation in decision-making processes. Yet another realm of water justice in which disputes are commonplace relates to the persistence of, and respect afforded to, Indigenous communities’ cultural traditions and values surrounding water—more ...

Brian S Dorr


Double-crested Cormorant (Phalacrocorax auritus) numbers have increased in North America, and con- comitantly cormorants appear to be expanding their nesting range in the southeastern United States.
Because colonial nesting waterbirds can impact water quality, soil chemistry and subsequent vegetation succession patterns, our goal was to assess the extent to which cormorant breeding colonies are influencing the biotic and abiotic attributes of forested islands in the southeastern United States. Our objectives were to (1) compare water quality characteristics in near-shore surface waters around forested islands with and without nesting cormorants during the peak-nesting/fledgling period and post-fledgling period, (2) measure soil ...


Assessing Non-Market Benefits Of Seagrass Restoration In The Gulf Of Gdańsk, Tobias Börger, Joanna Piwowarczyk 2016 Plymouth Marine Laboratory

Assessing Non-Market Benefits Of Seagrass Restoration In The Gulf Of Gdańsk, Tobias Börger, Joanna Piwowarczyk

Journal of Ocean and Coastal Economics

Seagrass meadows (Zostera marina) are an important ecosystem in the coastal environment of the Baltic Sea. This study employs a discrete choice experiment to value a set of non-market benefits provided by seagrass meadows in the Gulf of Gdańsk, Poland. The benefits valued in this study are a reduction of filamentous algae in the water and on the beach; access to seagrass meadows for boaters and divers; and improved water clarity. Results show significant willingness to pay for each attribute and differences of value estimates across different groups of survey respondents. It is discussed how to link choice attributes and ...


Preserving Biodiversity For A Climate Change Future: A Resilience Assessment Of Three Bay Area Species--Adenostoma Fasciculatum (Chamise), Arctostaphylos Canescens (Hoary Manzanita), And Arctostaphylos Virgata (Marin Manzanita), Alison S. Pollack 2016 University of San Francisco

Preserving Biodiversity For A Climate Change Future: A Resilience Assessment Of Three Bay Area Species--Adenostoma Fasciculatum (Chamise), Arctostaphylos Canescens (Hoary Manzanita), And Arctostaphylos Virgata (Marin Manzanita), Alison S. Pollack

Master's Projects

Anthropogenic climate change is an undeniable threat to the future of the natural world and human civilization. These shifts will have profound impacts on vegetation, especially for species endemic to isolated regions or sensitive to climate change factors. However, species resilience can predict success into the next century. Resilience is defined as the ability to withstand climate change factors, whereas vulnerability is defined as susceptibility to climate induced stress or damage.

Chaparral and coastal scrub ecosystems within the Bay Area of California provide a unique context for examining resilience, as many species are adapted to high temperatures, drought, and wildfire ...

Buffer Strips For Controlling Herbicide Losses, Steven K. Mickelson, James L. Baker

Steven K. Mickelson

Buffer strips are considered effective for reducing runoff of sediment and agricultural chemicals from cropland. In fact, buffer strips, or vegetative filter strips, have been suggested as a Best Management Practice to reduce nonpoint source pollution from cropland. This pollution can be great, especially if rainfall occurs shortly after a chemical has been applied.

The RDC kitchen facility has staff working around the clock and high consumption electrical, water, and gas appliances constantly running to parallel the high demand. The frequent use of commercial kitchen appliances results in an enormous consumption of energy and water resources leading to comparably high utility bills. Measuring the energy ...


Speleogenesis Of Critchfield Bat Caves And Associated Hydrogeology Of The Northern Edwards Aquifer, Williamson County, Texas, Ashley N. Landers 2016 Stephen F Austin State University

Speleogenesis Of Critchfield Bat Caves And Associated Hydrogeology Of The Northern Edwards Aquifer, Williamson County, Texas, Ashley N. Landers

Electronic Theses and Dissertations

Karst development in the Edwards Aquifer has been significantly studied in the San Antonio and Barton Spring Segments; however, karst development remains poorly studied in the Northern Segment. Detailed characterization of the Northern Segment is vital for future water conservation because of increasing urban sprawl along the Interstate 35 corridor. The Northern Segment of the Edwards Aquifer consists of Lower Cretaceous strata of the Comanche Peak, Edwards, and Georgetown formations. The stratigraphy is dominated by Edwards Limestone as it is the only formation that crops out in the study area.

Karst, stratigraphic, GIS, and geochemical studies were conducted to evaluate ...


The Ecological Impacts Of Non-Native Species On River Otter Populations, Nadia Swit 2016 Cleveland State University

The Ecological Impacts Of Non-Native Species On River Otter Populations, Nadia Swit

The Downtown Review

Most nonindigenous species invasions can have negative consequences on an environment. Trophic systems may become altered as prey sources are depleted, which can have further implications on community and habitat structure. However, some species invasions can be positive as it can provide another food source for key stone species. The effects of invasive species are reviewed in the following paper for the North American river otter (Lontra canadensis) and the Eurasian otter (Lutra lutra). In the case of the North American river, the introduction of the lake trout (Salvelinus namaycush) has negatively impacted otter populations, foraging behavior and bank ecology ...


Fluctuating Survival Selection Explains Variation In Avian Group Size, Charles R. Brown, Mary Bomberger Brown, Erin A. Roche, Valerie A. O'Brien, Catherine E. Page 2016 Department of Biological Sciences, University of Tulsa

Fluctuating Survival Selection Explains Variation In Avian Group Size, Charles R. Brown, Mary Bomberger Brown, Erin A. Roche, Valerie A. O'Brien, Catherine E. Page

Papers in Natural Resources

Most animal groups vary extensively in size. Because individuals in certain sizes of groups often have higher apparent fitness than those in other groups, why wide group size variation persists in most populations remains unexplained. We used a 30-y mark– recapture study of colonially breeding cliff swallows (Petrochelidon pyrrhonota) to show that the survival advantages of different colony sizes fluctuated among years. Colony size was under both stabilizing and directional selection in different years, and reversals in the sign of directional selection regularly occurred. Directional selection was predicted in part by drought conditions: birds in larger colonies tended to be ...
