Diets Of Nesting Swainson's Hawks In Relation To Land Cover In Northwestern North Dakota, Robert K. Murphy

The Prairie Naturalist

Relationships between land use practices and types of prey used by Swainson's hawks (Buteo swainsoni) in the Northern Great Plains is of increasing interest as the quantity and quality of habitat in the region declines. I recorded 1,284 prey items at 18 Swainson' s hawk nesting areas throughout northwestern North Dakota during summer 1986-1987. After correcting for detectability biases and food needs of adults, I estimated (90% CI) 2,087-2,859 total prey individuals and 138.3-206.7 kg of prey biomass (x = 69.8 g/item) were consumed by adult and nestling Swainson's hawks during my study. Major prey (>10% overall …

Multiple Criteria Decision Analysis For The Selection Of A Land Use Impact Method For A Life Cycle Assessment Of Switchgrass As A Bioenergy Feedstock In The Pee Dee Region Of South Carolina, Joel Kohn

All Theses

The interactions of a growing human population and increasing demand for food and energy have led to governmental and social pressures encouraging the adoption of biofuels as a substitute for fossil energy sources; however, several potential biofuel feedstocks can compete directly with food products for valuable land area. Life Cycle Assessment (LCA) is a tool that examines the environmental impacts of a product or process and can assist decision makers in the development of policy. The environmental impacts of land use are not well incorporated into LCA. As an emerging field, there is no consensus regarding the best methods by …

Effects Of Spatial Pattern And Economic Uncertainties On Freshwater Habitat Restoration Planning: A Simulation Exercise, Aimee H. Fullerton, E. Ashley Steel, Ian Lange, Yuko Caras

United States Department of Commerce: Staff Publications

Evaluating alternative future scenarios using simulation models is an emerging approach to conservation planning over large spatial and temporal extents. Such an approach is useful when predictions cannot be validated empirically; however, evaluating the sensitivity of scenario-based approaches to key uncertainties is necessary so that managers understand how real-world constraints might impact results. We used a simulation approach to investigate the sensitivity of freshwater habitat restoration plans to spatial pattern (e.g., project locations) and economic uncertainties (e.g., budget level and project costs) in a case study on Pacific salmon in the Lewis River Basin (WA, U.S.A.). We found that some …

Assessing Annual And Seasonal Spatial Variability Of Ambient Pm10 Using Linear Regression Analysis In A United States-Mexico Urban Sprawl, Mario Ivan Garcia

Open Access Theses & Dissertations

As air quality issues grow progressively in the consciousness of the global community, stakeholders are pressing for epidemiologic studies of air pollution. The effects of chronic exposure to ambient air pollution remain a difficult challenge due to its substantial small-scale spatial variation. Recent approaches to assess intra-urban exposure have employed the use of proximity-based assessment, interpolation methods, emission-meteorological models, dispersions models, and land-use regression (LUR) models.

This thesis assesses the spatial variability of ambient particulate matter (PM10) obtained by five self-governing models for the area of El Paso. Using multiple linear regression analysis five regression-based equations were developed to predict …

Estimated Area Of Impervious Parking Surfaces And The Potential Groundwater Recharge Increase Through Permeable Pavement Retrofit In The Chino Basin, Zablon Afera Adane

Theses Digitization Project

California recently declared a state of emergency over drought followiing three years of below average rain and snowfall. There is a consensus among many involved in water supply in California for finding new sources of water, conservation, and increasing recharge to replenish the groundwater with surface water that would have been lost to run off. This study investigates the amount of stormwater that could potentially be reinvested as groundwater recharge by simply transforming selected impermeable parking lots of the commercial, industrial, and institutional sectors into pervious pavement that allow water to infiltrate rather than be lost as urban runoff.

The Impacts Of Land Use And Development Patterns On Water Quality Of The Belgrade Lakes, Ian M. Mccullough

Honors Theses

The purpose of this study was to assess the impacts of patterns of land use and development on water quality in the Belgrade Lakes on a regional scale. Regional research and cooperation could identify key areas in the watershed where development or changing land use could have the greatest negative influences on lake water quality. Past work has centered on water chemistry, nutrient dynamics, development and economic factors but there has been no comprehensive analysis of land use and development history for the entire Belgrade Lakes Region. The Belgrade Lakes are a chain of 7 lakes in central Maine connected …
