Estimating Soil Seed Bank Characteristics In Ponderosa Pine Forests Using Vegetation And Forest-Floor Data, Scott R. Abella, Judith D. Springer Sep 2008

Estimating Soil Seed Bank Characteristics In Ponderosa Pine Forests Using Vegetation And Forest-Floor Data, Scott R. Abella, Judith D. Springer

Public Policy and Leadership Faculty Research

Soil seed banks are important for vegetation management because they contain propagules of species that may be considered desirable or undesirable for site colonization after management and disturbance events. Knowledge of seed bank size and composition before planning management activities facilitates proactive management by providing early alerts of exotic species presence and of abilities of seed banks to promote colonization by desirable species. We developed models in ponderosa pine (Pinus ponderosa) forests in northern Arizona to estimate the size and richness of mineral soil seed banks using readily observable vegetation and forestfloor characteristics. Regression models using three or fewer predictors …

Defining A Fire Year For Reporting And Analysis Of Global Interannual Fire Variablility, Luigi Boschetti, David P. Roy Aug 2008

Defining A Fire Year For Reporting And Analysis Of Global Interannual Fire Variablility, Luigi Boschetti, David P. Roy

GSCE Faculty Publications

The interannual variability of fire activity has been studied without an explicit investigation of a suitable starting month for yearly calculations. Sensitivity analysis of 37 months of global MODIS active fire detections indicates that a 1-month change in the start of the fire year definition can lead, in the worst case, to a difference of over 6% and over 45% in global and subcontinental scale annual fire totals, respectively. Optimal starting months for analyses of global and subcontinental fire interannual variability are described. The research indicates that a fire year starting in March provides an optimal definition for annual global …

Effects Of Exotic Invasive Vegetation On Breeding Birds Along The North Chickamauga Creek, Shannon Elaine Hatmaker Aug 2008

Effects Of Exotic Invasive Vegetation On Breeding Birds Along The North Chickamauga Creek, Shannon Elaine Hatmaker

Masters Theses and Doctoral Dissertations

The invasion of exotic plants into riparian areas of southeastern United States is a conservation concern not only for native plant communities, but also for wildlife. Breeding bird community structure could be particularly affected by such invasions and subsequent habitat changes as birds respond quickly to changes in habitat resources. During the 2007 breeding season, bird communities were surveyed using the line transect census method at four sites along the North Chickamauga Creek in Hamilton County, Tennessee. Two of the sites were regarded as being highly invaded by exotic understory plant species, while the other two sites remain relatively free …


Grassland Songbird Survival And Recruitment In Agricultural Landscapes: Implications For Source-Sink Demography, Noah G. Perlut, Allan M. Strong, Therese M. Donovan, Neil J. Buckley Jul 2008

Grassland Songbird Survival And Recruitment In Agricultural Landscapes: Implications For Source-Sink Demography, Noah G. Perlut, Allan M. Strong, Therese M. Donovan, Neil J. Buckley

Environmental Studies Faculty Publications

Population growth and decline are particularly sensitive to changes in three key life-history parameters: annual productivity, juvenile survival, and adult survival. However, for many species these parameters remain unknown. For example, although grassland songbirds are imperiled throughout North America, for this guild, only a small number of studies have assessed these parameters. From 2002 to 2006, in the agricultural landscape of the Champlain Valley of Vermont and New York, USA, we studied Savannah Sparrow (Passerculus sandwichensis) and Bobolink (Dolichonyx oryzivorus) demography on four grassland treatments: (1) early-hayed fields cut before 11 June and again in early- …

Alien Invaders! Pre-Visit Lesson: Introduced And Invasive Species (Grade 6), Discover Mojave: Forever Earth Jul 2008

Alien Invaders! Pre-Visit Lesson: Introduced And Invasive Species (Grade 6), Discover Mojave: Forever Earth

Curriculum materials (FE)

In the “Alien Invaders!” program, students use the Forever Earth vessel to investigate how quagga mussels might affect Lake Mead. Students collect water quality data such as clarity, pH, and temperature to determine whether current habitat conditions would allow quagga mussels to survive and thrive. Students learn about the consequences the quagga mussels could have on the lake and its living and non-living resources. Using the knowledge they’ve gained, students create their own management plans to prevent the spread of quagga mussels to other waterways.

This activity involves students in the concepts of introduced and invasive species

Bacterial Source Tracking In The Sinking Creek Watershed Using Antibiotic Resistance Analysis And Ribotyping., Lisa Kathleen Gallagher

Electronic Theses and Dissertations

Fecal pollution of surface water is a significant environmental health issue. Indicator organisms are used to monitor microbial water quality, but often their presence does not coincide with the presence of pathogens. Bacterial source tracking is a term describing methods to determine the origin of fecal pollution based on bacterial traits. The objective of this research is to evaluate the use of 2 bacterial source tracking techniques, antibiotic resistance analysis (ARA) and ribotyping, to determine the sources of bacteria isolated from Sinking Creek. Based on the results of this study, ARA and ribotyping are not useful techniques for identifying sources …

Brunswick Me: De-Militarizing The Bnas, Anne Holland, Brett Richardson, Richard Barringer

Planning

Closure of the Brunswick Naval Air Station in 2011 will have profound economic impacts on the entire mid-coast Maine region of Maine, with an estimated loss of 6,500 jobs and $330 million annual income. Throughout the Base Realignment and Closure process, Brunswick, the region, and the State of Maine followed federal rules and developed the federally-funded Brunswick Local Redevelopment Authority (BLRA) to plan for reuse of the 3300 acre base. In its planning process, the BLRA adhered to a number of well thought-out Guiding Principles, including the use of extensive public participation and the consideration of “smart growth” principles and …


Sediment Cores Reveal Antarctica’S Warmer Past, Quirin Schiermeier May 2008

Sediment Cores Reveal Antarctica’S Warmer Past, Quirin Schiermeier

ANDRILL Research and Publications

A unique drilling project in the western Ross Sea has revealed that Antarctica had a much more eventful climate history than previously assumed. A new sediment core hints that the western part of the now-frozen continent went through prolonged ice-free phases — presumably offering a glimpse of where our warming world might be heading. Researchers reported initial results from ANDRILL, a US$30-million international drilling project, on April 16 at the assembly of the European Geosciences Union in Vienna. During the past two years, the team has extracted two cores, each containing some 1,200 meters of sediment, from the seabed below …

Nuclear Technologies In The Great Basin Oral History Project, Danielle Endres

Native American Forum on Nuclear Issues

Abstract:

The United States currently faces a nuclear waste crisis. According to a 2002 report by former Secretary of Energy Spencer Abraham, “We have a staggering amount of radioactive waste in this country.”1 The Department of Energy (DOE) estimates that by 2035 the U.S. will have approximately 115,000 metric tons of high-level nuclear waste, which exceeds the capacity of the proposed federal storage site at Yucca Mountain.2 Deciding where and how to store nuclear waste is a significant nuclear, environmental, and health policy issue. The decisions that we make about nuclear waste siting greatly impact the future of nuclear technologies …

A Comparison Of Agricultural And Urban Influences On Water Quality In South West Wa, Nardia Keipert, David Weaver, Robert Summers, Christian Zammit, Artemis Kitsios, Simon Neville, Martin Clarke Apr 2008

A Comparison Of Agricultural And Urban Influences On Water Quality In South West Wa, Nardia Keipert, David Weaver, Robert Summers, Christian Zammit, Artemis Kitsios, Simon Neville, Martin Clarke

Conference papers and presentations

In Western Australia, a number of coastal rivers and estuaries have suffered from eutrophication since the 1960’s. Often the focus of the threat to water quality in these areas has been agriculture because of its extensive nature and widespread use of highly soluble fertilisers. Over recent years a focus on nutrient inputs, outputs and nutrient balance in a number of projects provides an opportunity to compare the relative nutrient threats from the agricultural and urban sectors, placed in the context of increasing urbanisation and development. These disparate data sets also allow a comparison of nutrient inputs in each sector in …

Economists, Value Judgments, And Climate Change: A View From Feminist Economics, Julie A. Nelson Apr 2008

Economists, Value Judgments, And Climate Change: A View From Feminist Economics, Julie A. Nelson

Economics Faculty Publication Series

A number of recent discussions about ethical issues in climate change, as engaged in by economists, have focused on the value of the parameter representing the rate of time preference within models of optimal growth. This essay examines many economists' antipathy to serious discussion of ethical matters, and suggests that the avoidance of questions of intergenerational equity is related to another set of value judgments concerning the quality and objectivity of economic practice. Using insights from feminist philosophy of science and research on high reliability organizations, this essay argues that a more ethically transparent, real-world-oriented, and flexible economic practice would …
