Community-Based Evaluation Of The Air Toxic Provisions Of Title Iii Of The 1990 Clean Air Act Amendments : Risks, Costs And Benefits, Keith C. Silverman

Dissertations

Hazardous air pollutants (HAPs) are those pollutants that are known or suspected to cause cancer, serious health effects, or adverse environmental effects. People exposed to HAPs at sufficient concentrations and durations may have an increased risk of getting cancer or experiencing other health effects. The 1990 Amendments to the Clean Air Act (CAAA) directed the U.S. Environmental Protection Agency (USEPA) to use technology-based air pollution control measures to significantly reduce emissions of HAPs from major sources of air pollution, followed by a risk-based assessment to address any remaining or residual health risks.

This study retrospectively assessed the public health ...

Final Technical Report: Integrated Restoration Strategies Towards Weed Control On Western Rangelands, Robert Nowak Dec 2006

Final Technical Report: Integrated Restoration Strategies Towards Weed Control On Western Rangelands, Robert Nowak

All U.S. Government Documents (Utah Regional Depository)

Invasive species are having severe ecological (Mack et al. 2000) and economic (Pimentel et al. 2005) impacts on ecosystems around the world. Invasive species can alter many ecosystem processes (Crooks 2002, Walker & Smith 1997) including: water and nutrient availability, such as form and amount of N if the soil (Evans et al. 2001, Sperry et al. 2006); primary productivity, through shifts in growth rates or efficiency of resource use; disturbance regimes, including the type, frequency, and severity of disturbances such as fire (D’Antonio 2002); and community dynamics, such as species replacements (Alvarez & Cushman 2002). The economic losses and damages by invasive plants are estimated to be ~$34 billion in the US and ~$95 billion worldwide (Pimental et al. 2005). Although trade and human migrations ...

The Molecular And Ecophysiological Roles Of Rubisco Activase And Rubisco Activase Likes In Photosynthetic Thermal Regulation Of Acer Rubrum And Arabidopsis Thaliana , David Weston

All Dissertations

Determining the consequences of human impact on our current and future climate is proving to be to be one of the greater challenges in modern biology. Current global models employing coupled atmosphere and terrestrial carbon feedbacks range in their predictions from the inconsequential to that of vast food shortages and species extinctions. However, there is hope that the emergence of new molecular approaches will revolutionize our understanding of plant and animal responses to a changing environment, allowing for higher predictive power when scaling up from the level of the individual to ecosystem-scale processes. This dissertation is an initial attempt for ...


Fate Of Fish Production In A Seasonally Flooded Saltmarsh, Philip W. Stevens, Clay L. Montague, Kenneth J. Sulak Dec 2006

Fate Of Fish Production In A Seasonally Flooded Saltmarsh, Philip W. Stevens, Clay L. Montague, Kenneth J. Sulak

USGS Staff -- Published Research

Although saltmarshes are thought to enhance the productivity of open estuarine water, the mechanism by which energy transfer occurs has been debated for decades. One possible mechanism is the transfer of saltmarsh production to estuarine waters by vagile fishes and invertebrates. Monthly estimates of fish standing stock, net fish ingress, and predation were used to develop a bio-mass budget to estimates annual production of fishes and the relative yield to predatory fish, birds, and direct migration to the estuary. Annual production of saltmarsh fishes was estimated to 31.0 gm-2 saltmarsh, which falls within the range of previously reported ...

Fragmentation And Loss: A Gis View Of The Mojave Desert Tortoise Habitat, Linda J. Wallers Dec 2006

Fragmentation And Loss: A Gis View Of The Mojave Desert Tortoise Habitat, Linda J. Wallers

MS GIS Program Major Individual Projects

Landscapes are ever changing or being changed by natural forces or by human activities. The changes, over time, frequently result in more complex and fragmented landscape structures. Much of the fragmentation is due to human activities, primarily roads. Landscape indices, tools that identify and quantify landscape structure, provide statistical analysis of how the landscape is fragmented by roads and what, if any, habitat loss resulting from road-avoidance behavior might be present. The interpretation of the landscape indices can give scientists clues to where limited resources can be directed to preserve the habitat.

The desert tortoise habitat was chosen as the ...


Spatial Grain Size Sorting In Eolian Ripples And Estimation Of Wind Conditions On Planetary Surfaces: Application To Meridiani Planum, Mars, Douglas J. Jerolmack, David Mohrig, John P. Grotzinger, David A. Fike, Wesley A. Watters Dec 2006

Spatial Grain Size Sorting In Eolian Ripples And Estimation Of Wind Conditions On Planetary Surfaces: Application To Meridiani Planum, Mars, Douglas J. Jerolmack, David Mohrig, John P. Grotzinger, David A. Fike, Wesley A. Watters

Departmental Papers (EES)

The landscape seen by the Mars Exploration Rover (MER) Opportunity at Meridiani Planum is dominated by eolian (wind-blown) ripples with concentrated surface lags of hematitic spherules and fragments. These ripples exhibit profound spatial grain size sorting, with well-sorted coarse-grained crests and poorly sorted, generally finer-grained troughs. These ripples were the most common bed form encountered by Opportunity in its traverse from Eagle Crater to Endurance Crater. Field measurements from White Sands National Monument, New Mexico, show that such coarse-grained ripples form by the different transport modes of coarse- and fine-grain fractions. On the basis of our field study, and simple ...


What Does Height Really Mean? Part Iv: Gps Orthometric Heighting, Thomas H. Meyer, Daniel R. Roman, David B. Zilkoski Dec 2006

What Does Height Really Mean? Part Iv: Gps Orthometric Heighting, Thomas H. Meyer, Daniel R. Roman, David B. Zilkoski

Department of Natural Resources and the Environment Articles

This is the final paper in a four-part series examining the fundamental question, “What does the word height really mean?” The creation of this series was motivated by the National Geodetic Survey’s (NGS) embarking on a height modernization program as a result of which NGS will publish measured ellipsoid heights and computed Helmert orthometric heights for vertical bench marks. Practicing surveyors will therefore encounter Helmert orthometric heights computed from Global Positioning System (GPS) ellipsoid heights and geoid heights determined from geoid models as their published vertical control coordinate, rather than adjusted orthometric heights determined by spirit leveling. It is ...

Grassland Songbirds In A Dynamic Management Landscape: Behavioral Responses And Management Strategies, Noah G. Perlut, Allan M. Strong, Therese M. Donovan, Neil J. Buckley

Environmental Studies Faculty Publications

In recent decades, earlier and more frequent harvests of agricultural grasslands have been implicated as a major cause of population declines in grassland songbirds. From 2002 to 2005, in the Champlain Valley of Vermont and New York, USA, we studied the reproductive success of Savannah Sparrows (Passerculus sandwichensis) and Bobolinks (Dolichonyx oryzivorus) on four grassland treatments: (1) early-hayed fields cut before 11 June and again in early- to mid-July; (2) middle-hayed fields cut once between 21 June and 10 July; (3) late-hayed fields cut after 1 August; and (4) rotationally grazed pastures. Both the number of fledglings per female per ...
