Revegetating Burned Arid Lands: Identifying Successful Native Species Using Trait And Competition Analysis: Final Report, Scott R. Abella Dec 2010

Revegetating Burned Arid Lands: Identifying Successful Native Species Using Trait And Competition Analysis: Final Report, Scott R. Abella

Fire Science

Species selection can make the difference between successful revegetation projects and costly failures. Candidate native species for revegetating burned arid lands in the southwestern United States must meet at least two criteria. These species must: (1) be competitive in postfire environments typically dominated by exotic grasses, and (2) be able to become established reliably by seeding or planting. In response to Manager’s Request Task 3 (reestablishment of native vegetation after fires on arid lands) in the 2006 JFS announcement for proposals, this research tackled the problem of selecting native species with the greatest chance of revegetation success by conducting ...

Ecological Impacts Of Stream Bank Stabilization In A Great Plains River, Christopher M. Pracheil Dec 2010

Ecological Impacts Of Stream Bank Stabilization In A Great Plains River, Christopher M. Pracheil

Dissertations & Theses in Natural Resources

Reduced ecological complexity, decreased water quality, and accelerated stream bank erosion are common disturbances in rivers with agriculturally dominated watersheds. Massive bank failures, increased sediment loads, and decreased riverine habitat are current problems in the agriculturally dominated Cedar River of central Nebraska. In an effort to slow erosion and prevent further ecological degradation, 20 reach scale stream bank stabilization projects were installed on the Cedar River from 2001 to 2004. The objective of this study was to determine the impact of the Cedar River stream bank stabilization projects on the ecological conditions within the Cedar River. Stream bank erosion, suspended ...

Policy And Science Of Geothermal Heat Use At Mcmurdo Station, Antarcrtica, Joe Alvine Dec 2010

Policy And Science Of Geothermal Heat Use At Mcmurdo Station, Antarcrtica, Joe Alvine

Environmental Studies Undergraduate Student Theses

My thesis research project deals with the use of geothermal heat in Antarctica. Currently it is not allowed due to article 7 of the 1991 Protocol on Environmental Protection that placed a 50 moratorium on the exploitation of mineral resources. The US main base in Antarctica, McMurdo Station is currently powered by diesel generators that are inefficient, cause environmental damage, and is expensive to run. By exploring alternative energy options, McMurdo Station can reduce its dependence on non-renewable energy sources. By determining the geothermal potential of McMurdo Station, this project explores the possibilities and benefits that would occur with the ...


Recent Legislation To Promote Wind Energy In Nebraska, Ryan Lemke Dec 2010

Recent Legislation To Promote Wind Energy In Nebraska, Ryan Lemke

Environmental Studies Undergraduate Student Theses

Nebraska is currently ranked 4th in the nation for wind energy potential, but ranks low in actual wind power production. The lack of wind energy production could be the result of Nebraska’s unique public power districts that have eminent domain of distribution and retail sales of electricity in the State. Public Power districts are prohibited from receiving benefits of state and federal tax incentives for the development of wind farms, however some Nebraska power districts still pursue wind energy as a renewable source of energy.

Recent legislation changes, including the passing of laws LB629 and LB1048, have provided the ...

The Hydrology Of The Carroll Cave-Toronto Springs System: Identifying And Examining Source Mixing Through Dye Tracing, Geochemical Monitoring, Seepage Runs, And Statistical Methods, Benjamin Verlinden Miller

Masters Theses & Specialist Projects

In karst areas relationships between activities occurring on the surface and the overall health of the subsurface environment are often highly interconnected. However, the complex nature of karst flow systems can often make identification of these connections difficult. Carroll Cave, a large stream cave system located in the central Missouri Ozarks, is known for its biological and speleological significance. A dye tracing project to delineate a Carroll Cave recharge area through dye tracing has identified an area of 18.5 km2 which contributes water to the cave. The water from Thunder River within Carroll Cave was positively traced to eight ...

Patterns Of Heavy Metal Concentration In Core Sediments, Wilgreen Lake, Madison County, Kentucky, Clint Mcmaine, Walter S. Borowski Nov 2010

Patterns Of Heavy Metal Concentration In Core Sediments, Wilgreen Lake, Madison County, Kentucky, Clint Mcmaine, Walter S. Borowski

EKU Faculty and Staff Scholarship

Elevated levels of cadmium, copper, lead, and nickel were found within the waters of Wilgreen Lake during a preliminary survey in 2007. Accumulation of heavy metals in freshwater systems is a known problem. Heavy metals enter the lake in the dissolved phase or adsorbed onto sediment particles and may be linked to industries within the lake’s watershed. Under certain geochemical conditions such as anoxia, heavy metals may detach from sediment particles and diffuse into overlying lake waters, causing a renewed influx of heavy metals into the ecosystem. We hypothesize that heavy metals should decrease in concentration upcore as a ...

The transformation of landscapes from rural to urban land use impacts affected ecosystems. Replacing natural vegetation with impervious surfaces and introducing environmental stressors through increased human activity can significantly alter aquatic ecosystems. This study examined the effects that urbanization had on salinity, dissolved oxygen, temperature, conductivity, and pH of aquatic systems along an urban-rural gradient in Illinois, Chicago land area- Little Calumet River, Thorn Creek, and Kankakee River. The first objective of this project was to examine whether there were changes or fluctuations among various environmental parameters that may be due to heavily populated residential areas when compared to a ...


Trace Metal Concentrations Across Trophic Levels In Cotton Fields Of Xinjiang Province, China, Jessica Quinn Oct 2010

Trace Metal Concentrations Across Trophic Levels In Cotton Fields Of Xinjiang Province, China, Jessica Quinn

All Student Theses

Trace metals become concentrated in urban and peri-urban soils with the use of agricultural practices and industrial emissions. Fertilizers, liming, sewage sludge, and irrigation water contain metals which accumulate in agricultural fields and pose a risk to humans and wildlife. Coal plants and brickyards release metals into the atmosphere which are deposited on soil and plant surfaces. This research quantifies the concentrations of nine trace metals in three different soil types. A total of 116 rodents were sampled in cotton fields and a desert. Cotton plants and triplicate soil samples were collected with each rodent capture. Soil samples were analyzed ...

Treatment Of Odorous Vocs With Ultraviolet Light, Jacek A. Koziel, Xiuyan Yang, Johannes Van Leeuwen, William S. Jenks, Yael Laor

Agricultural and Biosystems Engineering Publications

Livestock production systems are associated with aerial emissions of odor, volatile organic compounds (VOCs), and other gases. Control of those emissions is needed to assure compliance with environmental regulations and long-term viability of the industry. This research focuses on abatement of livestock odors using advanced oxidation processes including UV irradiation. Effects of several variables including UV wavelength, dose, and the presence of catalyst on removal of gases causing livestock odor were tested in a flow-through photoreactor. These gases included H(2)S, mercaptans, volatile fatty acids, and phenolic compounds. Standard UV lamps with principal output at 254 nm and 185 ...


Barchan-Parabolic Dune Pattern Transition From Vegetation Stability Threshold, Meredith D Reitz, Douglas J. Jerolmack, Ryan C. Ewing, Raleigh L Martin Oct 2010

Barchan-Parabolic Dune Pattern Transition From Vegetation Stability Threshold, Meredith D Reitz, Douglas J. Jerolmack, Ryan C. Ewing, Raleigh L Martin

Departmental Papers (EES)

Many dune fields exhibit a downwind transition from forward-pointing barchan dunes to stabilized, backward-pointing parabolic dunes, accompanied by an increase in vegetation. A recent model predicts this pattern transition occurs when dune surface erosion/deposition rates decrease below a threshold of half the vegetation growth rate. We provide a direct test using a unique data set of repeat topographic surveys across White Sands Dune Field and find strong quantitative support for the model threshold. We also show the threshold hypothesis applied to a barchan dune results naturally in its curvature inversion, as the point of threshold crossing progresses from the ...

Eelgrass Distribution In The Great Bay Estuary For 2009 : Final Report, Frederick T. Short Sep 2010

Eelgrass Distribution In The Great Bay Estuary For 2009 : Final Report, Frederick T. Short

PREP Reports & Publications

Eelgrass in the Great Bay Estuary in 2009 was once again present only in Great Bay itself and in Portsmouth Harbor. For the second year in a row, there was no eelgrass in Little Bay or in the Piscataqua River. In 2009, there was a continued loss of eelgrass biomass in Great Bay; there has been a 66.4% loss of biomass in Great Bay since 1996 and distribution is 30% less than in 1996. Although eelgrass distribution in Great Bay itself increased between 2008 and 2009, primarily due to continued expansion from natural seeding of bare areas, the Bay ...

Modeling The Effects Of Pasture Expansion On Emissions From Land-Use Change, Jerome R. F. Dumortier, Dermot J. Hayes, Miguel Carriquiry, Fengxia Dong, Xiaodong Du, Amani E. Elobeid, Jacinto F. Fabiosa, Kranti Mulik Sep 2010

Modeling The Effects Of Pasture Expansion On Emissions From Land-Use Change, Jerome R. F. Dumortier, Dermot J. Hayes, Miguel Carriquiry, Fengxia Dong, Xiaodong Du, Amani E. Elobeid, Jacinto F. Fabiosa, Kranti Mulik

CARD Working Papers

We present a global agricultural greenhouse gas model that assesses emissions from land-use change. In addition to evaluating shifts in and out of crop production, we develop a pasture model to assess extensification and intensification of global livestock production based on herd size and stocking rate. We apply the model to a scenario that introduces a tax on methane emissions from cattle in the United States. The resulting expansion of pasture in the rest of the world leads to substantially higher emissions than without the tax. The yearly average emissions from the tax are 260 metric tons of CO2-equivalent.


Climate Change, Its Effect On Migration Patterns Of The Cackling Goose And White-Fronted Goose In The Willamette Valley, And Implications For Goose Management, Kelly Warren Sep 2010

Climate Change, Its Effect On Migration Patterns Of The Cackling Goose And White-Fronted Goose In The Willamette Valley, And Implications For Goose Management, Kelly Warren

Master of Environmental Management Project Reports

This thesis considers the question of whether climate change is affecting the migration patterns of geese in the Pacific Flyway, specifically cackling geese (Branta hutchinsii minima) and Pacific white-fronted geese (Anser albifrons frontalis). Ancillary questions that are considered are as follows:

• If global warming is affecting these species, what is the nature of the effects? • How are the changes affecting the human environment and what can be done about these effects?

In 1994, the majority of the cackler population in the Pacific Flyway began to winter in Oregon’s Willamette Valley rather than in their historical wintering areas in California ...

Shoreline Evolution: City Of Portsmouth, Virginia Hampton Roads And Elizabeth River Shorelines, Donna A. Milligan, Kevin O'Brien, Christine Wilcox, C. Scott Hardaway Jr.

Reports

Shoreline evolution is the change in the shore zone through time. Along the shores of Chesapeake Bay, it is a process and response system. The processes at work include winds, waves, tides and currents which shape and modify coastlines by eroding, transporting and depositing sediments. The shore line is commonly plotted and measured to provide a rate of change, but it is as important to understand the geomorphic patterns of change. Shore analysis provides the basis to know how a particular coast has changed through time and how it might proceed in the future.

The purpose of this data report ...
