The Distance From Necessity: A Bourdieusian Analysis Of Gathering Practices In Vermont, 2014 Antioch University
The Distance From Necessity: A Bourdieusian Analysis Of Gathering Practices In Vermont, Alan Robert Pierce
Dissertations & Theses
This study examines why contemporary Americans continue to gather wild plants and fungi. Vermont, a state with a rich history of gathering, serves as a study site. I interviewed twenty-four gatherers using ethnographic methods. I applied a Bourdieusian framework to analyze the differences between gathering practices as they related to gathering knowledge, views of nature, and uses of gathered products. The interviews indicated that gathering is important to the physical and mental well-being of its practitioners and instills a connection to nature as well as to place. Interviewees cited spending time in nature and enjoyment of engaging the senses as ...
The Conservation Value Of Karst Dolines For Vascular Plants In Woodland Habitats Of Hungary: Refugia And Climate Change, 2014 University of South Florida
The Conservation Value Of Karst Dolines For Vascular Plants In Woodland Habitats Of Hungary: Refugia And Climate Change, Zoltán Bátori, János Csiky, Tünde Farkas, E. Anna Vojtkó, László Erdős, Dániel Kovács, Tamás Wirth, László Körmöczi, András Vojtkó
International Journal of Speleology
Limestone (karst) surfaces in Hungary are rich in dolines, in which many endangered vascular plant species occur. To date, the majority of studies dealing with doline vegetation have focused on the local rather than the landscape level, without using comparative data from other areas. However, in this study we aimed to compare the vegetation pattern and species composition of dolines under different climate regimes of Hungary with regard to regional species pools. The fieldwork was carried out between 2005 and 2012. Twenty dolines were selected in the Mecsek Mountains (southern Hungary) and nine dolines in the Aggtelek Karst area (northern ...

Influence Of Mountain Pine Beetle On Fuels, Foliar Fuel Moisture Content, And Litter And Volatile Terpenes In Whitebark Pine, Chelsea Toone
All Graduate Theses and Dissertations
Mountain pine beetle (Dendroctonus ponderosae Hopkins) has caused extensive tree mortality in whitebark pine (Pinus albicaulis Engelm) forests. Previous studies conducted in various conifer forests have shown that fine surface fuels are significantly altered during a bark beetle outbreak. Bark beetle activity in conifer stands has also been shown to alter foliar fuel moisture content and chemistry over the course of the bark beetle rotation.
The objective of this study was to evaluate changes to fine surface fuels, foliar fuel moisture and chemistry and litter chemistry in and under whitebark pine trees infested by mountain pine beetle. Fuels were measured ...
Maximizing Lignin Yield Using Experimental Design Analyzing The Impact Of Solvent Composition And Feedstock Particle Size On The Organosolv Process In The Presence Of Feedstock Contamination, 2013 University of Tennessee, Knoxville
Maximizing Lignin Yield Using Experimental Design Analyzing The Impact Of Solvent Composition And Feedstock Particle Size On The Organosolv Process In The Presence Of Feedstock Contamination, Hagen Maraun
The depletion of fossil feedstock and the unfavorable environmental effects accompanying by its exploitation are the driving forces in the process of transitioning to renewable feedstock as the primary resource. Similar to petrorefineries, a new modern biorefinery would use biomass to produce a variety of different chemical products and transportation fuels. Lignin, a potential low-cost, high volume output process stream derived from lignocellulosic biomass is currently being researched to better support the economics of the future biorefinery. In this study, experimental design was used to determine the optimal level for each process factor in an organosolv fractionation process that targets ...

Conservation In The Context Of Climate Change: Practical Guidelines For Land Protection At Local Scales, Kevin Ruddock, Peter August, Christopher Damon, Charles Labash, Pamela Rubinoff, Donald Robadue Jr.
Natural Resources Science Faculty Publications
Climate change will affect the composition of plant and animal communities in many habitats and geographic settings. This presents a dilemma for conservation programs – will the portfolio of protected lands we now have achieve a goal of conserving biodiversity in the future when the ecological communities occurring within them change? Climate change will significantly alter many plant communities, but the geophysical underpinnings of these landscapes, such as landform, elevation, soil, and geological properties, will largely remain the same. Studies show that extant landscapes with a diversity of geophysical characteristics support diverse plant and animal communities. Therefore, geophysically diverse landscapes will ...
National Park Service Cave Ecology Inventory And Monitoring Framework, 2013 University of South Florida
National Park Service Cave Ecology Inventory And Monitoring Framework, Gretchen M. Baker, Steven J. Taylor, Shawn Thomas, Rick Olson, Kathy Lavoie, Marie Denn, Steven Thomas, Hazel Barton, Kurt Helf, Rene Ohms, Joel Despain, Jim Kennedy, David Larson
National Cave and Karst Management Symposium 2013
A team developed the Cave Ecology Inventory and Monitoring Framework for National Park Service (NPS) units. It contains information for NPS cave managers across the United States to determine how to inventory and monitor cave ecology. Due to the wide geographical scope of NPS caves and their many different types, the document does not prescribe exact protocols. Instead, it provides guidance for what types of inventory and monitoring are possible, a framework for deciding how to prioritize inventory and monitoring activities, and references to specific protocols that are already in place at NPS cave parks.

Incorporating Cave And Karst Management Into The Forest Plan Revision Process Of Arizona Forests, 2013 University of South Florida
Incorporating Cave And Karst Management Into The Forest Plan Revision Process Of Arizona Forests, Ray Keeler, Richard Bohman
National Cave and Karst Management Symposium 2013
Arizona National Forest land managers have a multitude of tasks and priorities; historically, caves and karst management has not been amongst the priorities receiving any significant allocation of resources. When caves and karst management is not included in the Forest Plan, even when large and significant cave and karst areas exist, active cave and karst management often falls below the waterline of available manpower and resources. Additionally, there is entropy associated with normal changes in personnel assignments and new staff coming onboard. When combined with a general lack of written policies and guidelines, these personnel transitions lead to unnecessary degradation ...

Environmental Science and Management Faculty Publications and Presentations
Understanding how climate change may influence forest carbon (C) budgets requires knowledge of forest growth relationships with regional climate, long-term forest succession, and past and future disturbances, such as wildfires and timber harvesting events. We used a landscape-scale model of forest succession, wildfire, and C dynamics (LANDIS-II) to evaluate the effects of a changing climate (A2 and B1 IPCC emissions; Geophysical Fluid Dynamics Laboratory General Circulation Models) on total forest C, tree species composition, and wildfire dynamics in the Lake Tahoe Basin, California, and Nevada. The independent effects of temperature and precipitation were assessed within and among climate models. Results ...

Las Raíces De La Deforestación En El Departamento Pando, 2013 SIT Graduate Institute/SIT Study Abroad
Las Raíces De La Deforestación En El Departamento Pando, Jeremy Levine-Drizin
Independent Study Project (ISP) Collection
This research paper examines the phenomenon of the recent trend of deforestation in the Pando department in northwestern Bolivia. Historically, the economy of Pando has always been based primarily in agro-forestal extraction activities that provided income to communities without the need to destroy the surrounding forests. The most important of these agro-forestal products have been rubber (primarily during the beginning of the 20th century) and more recently Castaña (Brazilian Nut). Recently however, as the result of various forces, the inhabitants of Pando have begun to cut down there forests at an alarming rate. The most relevant causes of this phenomenon ...

Why I Love Grasshopper Sparrows, Michele Patenaude
UVM Libraries Conference Day
Since 2001, Michele (a library circulation supervisor in her day job) has conducted a summer breeding-bird survey of Grasshopper Sparrows at Camp Johnson in Colchester, VT. Named Grasshopper Sparrows because their breeding call sounds like a grasshopper, this little brown bird is endemic to certain types of scrubby grasslands which are becoming more scarce in the Northeast. The Grasshopper Sparrow is also declining and the species is not on the list of Vermont Endangered Birds. Come to this presentation and learn about the bird, how Michele surveys them, why they are endangered, and why Michele loves these quiet, little brown ...
Mp762: Harvesting Equipment Cycle Time And Productivity Guide For Logging Operations In Maine, 2013 The University of Maine
Mp762: Harvesting Equipment Cycle Time And Productivity Guide For Logging Operations In Maine, Patrick Hiesl, Jeffrey G. Benjamin
This guide provides cycle time and productivity information for harvesting equipment commonly used in Maine’s logging industry for partial harvests. Data were collected in terms of time consumption per work task. With these data, cycle time equations were developed. Productivity functions were developed using tree volumes. It is important to remember that productivity may vary from stand to stand due to differences in tree volume at the site level. Cycle time functions are independent of tree volume and will give fairly accurate predictions of time consumption per machine.
Dendrochronological Reconstruction Of Fire, Bogus Basin Area Boise National Forest, 2013 Boise State University
Dendrochronological Reconstruction Of Fire, Bogus Basin Area Boise National Forest, Amy L. Cutter
Student Research Initiative
Since people have settled along the Boise Front, there have been very few documented fire disturbances. This is likely an outcome of fire suppression policies. There is evidence, visible as scars on living trees, that the old growth ponderosa pines located on the East Side Trail in the Boise National Forest have withstood multiple fires. Samples were collected by using a chainsaw to remove small, partial cross-sections from several trees. The Boise Front master chronology was used to accurately cross-date the fire-scarred samples using COFECHA. Analysis of the samples revealed ten fire events ranging from 1709 to 1889. The fire ...

Understanding Relationships Among Abundance, Extirpation, And Climate At Ecoregional Scales, Erik A. Beever, Soloman Z. Dobrowski, J. Long, A. R. Mynsberge, N. B. Piekielek
Forest Management Faculty Publications
Recent research on mountain-dwelling species has illustrated changes in species' distributional patterns in response to climate change. Abundance of a species will likely provide an earlier warning indicator of change than will occupancy, yet relationships between abundance and climatic factors have received less attention. We tested whether predictors of counts of American pikas (Ochotona princeps) during surveys from the Great Basin region in 1994-1999 and 2003-2008 differed between the two periods. Additionally, we tested whether various modeled aspects of ecohydrology better predicted relative density than did average annual precipitation, and whether risk of site-wide extirpation predicted subsequent population counts of ...

Post-Fire Response Of Little Creek Watershed: Evaluation Of Change In Sediment Production And Suspended Sediment Transport, 2013 California Polytechnic State University
Post-Fire Response Of Little Creek Watershed: Evaluation Of Change In Sediment Production And Suspended Sediment Transport, Andrew Wood Loganbill
Master's Theses and Project Reports
The Little Creek watershed was assessed to identify changes in event-based suspended sediment export and determine the factors contributing to sediment production the first year following the Lockheed Fire in 2009. The amount and volume of near-stream sediment sources were found to decrease, while an increase in hillslope sediment production was documented. High intensity, short duration rainfall (up to 87 mm/hr for 10 minute duration) initiated extensive rilling and minor channel-derived debris torrents originating from the upper south facing slopes. Rainfall simulations, hillslope erosion plots, and soil infiltration tests indicated that fire produced soil water repellency, the lack of ...

Habitat Type Mapping In Montana De Oro State Park Through Gis Image Classification, Evan Corrales, Sarah Fockler
Natural Resources Management and Environmental Sciences
This project involved using aerial imagery and GIS procedures to automatically map the basic vegetation communities present within Montana de Oro State Park, CA: grassland, coastal scrub, bare ground, woodland, and riparian areas. 1m resolution color imagery of the park from the NAIP 2005 (National Agriculture Inventory Program) and 1m resolution LiDAR height data were also used to determine the locations of the different vegetation types in the park. This data was then classified by color using the interactive supervised classification tool in ArcGIS. Points were taken in the park using a GPS unit, and compared with the GIS results ...
Variability In Soil Climate And Respiration On Managed Timber Stands: A Case Study In Southwest Oregon, 2013 California Polytechnic State University
Variability In Soil Climate And Respiration On Managed Timber Stands: A Case Study In Southwest Oregon, Scott Pensky, Adrian Gallo
Natural Resources Management and Environmental Sciences
Thinning of forested lands and timber stands in the Pacific Northwest have taken place for centuries with a limited understanding of how the alterations may affect ecosystem functions. The goal of this study was to examine the soil climate and microbial activity on a seasonal timescale of thinning practices examined at different stages of succession. Two timber stands in Southwestern Oregon within the Grayback Creek Watershed were chosen because of identical forest management techniques separated by a 10-year treatment interval (40% variable density thinning). Field methods and equipment measured canopy coverage, soil moisture and temperature at 3 depths (5, 15 ...
