Assessment Of Black Carbon In Snow And Ice From The Tibetan Plateau And Pacific Northwest, Matthew Glen Jenkins

All Master's Theses

An ice core from Mt. Geladandong, Tibetan Plateau, spanning 1853-1983, and snow samples collected over two winters from the Cascade Mountains were analyzed for concentrations of black carbon (BC) using a Single Particle Soot Photometer (SP2). From the ice core, the high-resolution BC record displayed substantial variability, a 2-fold increase in peak concentrations from 1853-1930 to 1930-1983, and a 1.6-fold increase in average concentrations from 1853-1975 to 1975-1983. Concentrations were also higher than at two areas closer to BC sources and analyzed by the same method. In the Pacific Northwest, BC concentrations varied seasonally and annually, with the highest concentrations …

Environmental Science and Management Professional Master's Project Reports

In an attempt to successfully address and reduce contamination from toxic chemicals and other pollutants in the Oregon environment, the Oregon Department of Environmental Quality is in the early stages of developing a comprehensive agency-wide toxics reduction plan. The plan seeks to find a more efficient, sustainable approach to addressing contaminants of concern to human and ecological health. Team Toxics, a work group compromised of members from various DEQ departments, has been created to collaborate and create the framework for developing these strategies. In summer 2009, Team Toxics was in the very early stages of development, and found the need …

The Sociology Of Landowner Interest In Restoring Fire-Adapted, Biodiverse Habitats In The Wildland-Urban Interface Of Oregon's Willamette Valley Ecoregion, Max Nielsen-Pincus

Environmental Science and Management Faculty Publications and Presentations

In many parts of the world, the combined effects of wildfire, climate change, and population growth in the wildland-urban interface pose increasing risks to both people and biodiversity. These risks are exemplified in western Oregon’s Willamette Valley Ecoregion, where population is projected to double by 2050 and climate change is expected to increase wildfire risk. Restoring elements of the region’s historic fire-adapted prairie, savanna, and woodland habitats may help to reduce future wildfire risk and help conserve the region’s threatened biodiversity. We report on a mail survey (n = 939) examining the socio-demographic factors influencing private landowners’ likelihood of restoring …

New Mexico’S Major Reservoirs: An Overview, Susan Kelly, Diego Urbina

Water Matters!

This paper describes the salient facts about the major water storage reservoirs in New Mexico. For each reservoir, we address the purposes of water storage allowed by law, storage capacity, the responsible operating agency, and some key operational issues. This is by necessity a vast simplification of the topic.Books, articles, research reports, operation manuals, and other materials on these topics run into the hundreds. Millions of dollars have been spent on technical studies and computer models to understand,and sometimes alter, the operations of various dams and reservoirs.

A Green Board As A Climate-Change Imperative: Appointing A Climate-Change Expert To The Audit Committee, Porcher L. Taylor Iii, Harris L. Kay

School of Professional and Continuing Studies Faculty Publications

This article makes the innovative and timely case for a climate change imperative: a green board. Urgency is evident, with the arrival of "a fast-emerging new burden on board members to oversee their company's posture on climate change and to begin monitoring an area that, until now, has drawn scant attention in the boardroom."²¹ One major impetus for the proposal advocated in this Article is that there is apparently a dearth of green boards in corporate America.²² In contrast, European and Canadian companies appear to be at the vanguard of utilizing green boards.²³

The Effects Of Urban Habitat Fragmentation On The Population Genetic Structure Of The Scincid Lizard Ctenotus Fallens, Jösef Krawiec

Theses : Honours

Species occurring in fragmented urban habitats often exhibit low genetic diversity which can be attributed to restricted gene flow and elevated levels of inbreeding. This can have serious implications for the survival of species especially when faced with additional pressures caused by urbanisation. The population genetic structure of the generalist skink Ctenotus fallens was examined within and among three urban vegetation remnants in the Perth metropolitan area in Western Australia, using both microsatellite and AFLP markers. Historic genetic connectivity between the populations of each remnant was shown as well as weak patterns of genetic differentiation which appeared to suggest isolation …

High aerosol loading over the northern Indian subcontinent can result in poor air quality leading to human health consequences and climate perturbations. The international 2008 TIGERZ experiment intensive operational period (IOP) was conducted in the Indo-Gangetic Plain (IGP) around the industrial city of Kanpur (26.51 degrees N, 80.23 degrees E), India, during the premonsoon (April-June). Aerosol Robotic Network (AERONET) Sun photometers performed frequent measurements of aerosol properties at temporary sites distributed within an area covering similar to 50 km(2) around Kanpur to characterize pollution and dust in a region where complex aerosol mixtures and semi-bright surface effects complicate satellite retrieval …

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 synergistic …

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

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

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 …

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 springs …

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

Department of 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 …

Is Orthoptera Abundance And Distribution Across A Small Grassland Area Affected By Plant Biomass, Plant Species Richness, And Plant Quality?, Caitlin Falcone

Department of Environmental Studies: Undergraduate Student Theses

The choice of a specific microhabitat represents a compromise among a number of different factors organisms use to monitor habitat suitability. Grassland vegetation structure can vary widely along environmental gradients over a relatively small area. This vegetation structure can have a large influence on habitat selection by grasshoppers (Orthoptera). However, it is not clear which vegetation characteristics are most important in determining grasshopper abundance. We found that plant biomass, plant species richness, and plant quality all have an effect on grasshopper abundance and distribution. We observe that these affects vary both within and among the two years of data collection. …

Characterization Of Watersheds On Fort Benning Military Reservation: Comparison Of Field Data To Watershed Parameters, Melinda Rosetta Stahl

Theses and Dissertations

Sixteen watersheds located on Fort Benning Military Installation in Georgia were analyzed using both physically collected data and computer modeling data. Physical data collected included total suspended solids (TSS) and grain size analysis using the Wolman Pebble Count method. Computer modeling analyzed the watersheds using ArcGIS 9.3 for comparison to physical data. Land use, slope, and soil data were used in a modified revised universal soil loss equation (RUSLE) to create a soil erodibility index map. Wolman Pebble Count data showed that in half of the watersheds, 84% of the sampled grains were less than half a millimeter in size. …

Tracking Floral Visitation Using Dna Barcodes, Ivan Ray Shoemaker

Theses and Dissertations

Floral visitation resulting in interspecific pollen transfer (IPT) from non-native or invasive plant species can affect the reproductive fitness of native plant species through pollen allelopathy, stigma clogging, stylar clogging, and ovule (seed) discounting. The prevalence of IPT and the importance of pollinators in mediating its impacts, however, remain poorly understood. Although most traditional methods for examining visitor movement are insufficient for determining rates of potential IPT, one promising alternative is the use of DNA barcoding. Because floral visitors eat, collect or unknowingly obtain pollen, nectar and other floral tissues, plant DNA should be recoverable from their bodies, permitting molecular …
