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 ...
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 ...

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 ...
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 Initiatives
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 ...
Harvesting Equipment Cycle Time And Productivity Guide For Logging Operations In Maine, Miscellaneous Publication 762, 2013 The University of Maine
Harvesting Equipment Cycle Time And Productivity Guide For Logging Operations In Maine, Miscellaneous Publication 762, 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.

Understanding Relationships Among Abundance, Extirpation, And Climate At Ecoregional Scales, 2013 University of Montana
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 ...

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 ...
Mechanisms Of Nutrient Limitation And Nutrient Acquisition In Managed And Unmanaged Forest Ecosystems, 2013 University of New Hampshire
Mechanisms Of Nutrient Limitation And Nutrient Acquisition In Managed And Unmanaged Forest Ecosystems, Matthew A. Vadeboncoeur
Understanding the interactions between global change, human and natural disturbances, and other factors on biogeochemical processes in forests is necessary to ensure the sustainability of forest management. Here I report the results of several investigations into nutrient acquisition processes in the forests of New Hampshire. I begin with a meta-analysis of fertilization studies showing that phosphorus (P) and calcium (Ca) as well as nitrogen (N) may limit primary production in deciduous forests of the region. Because these limiting nutrients are all removed from the ecosystem when trees are harvested, I compared nutrient budgets under a range of harvesting scenarios with ...
The Effects Of Fire On The Vernal Herbs Of An Eastern Mesic Forest, 2013 Western Kentucky University
The Effects Of Fire On The Vernal Herbs Of An Eastern Mesic Forest, David Randolph Kem
Masters Theses & Specialist Projects
The effects of fire on vernal herbs of the mesic forests of eastern North America are poorly understood. I studied the influence of prescribed fire on species richness, abundance of rare and common species, and density of exotics in the vernal herbaceous layer. To determine these effects, three sites in central Kentucky were surveyed prior to and following one of three treatments: spring burn, winter burn, or negative control. I conducted low-intensity spring burns in April 2010 and winter burns in February 2011. I used chi square analyses to test for changes in species richness, abundance of rare species, abundance ...
Forest Recovery, Nutrient Cycling And Carbon Sequestration In A Southern Appalachian Spruce-Fir Forest, 2013 Utah State University
Forest Recovery, Nutrient Cycling And Carbon Sequestration In A Southern Appalachian Spruce-Fir Forest, Patrick T. Moore
All Graduate Theses and Dissertations
In order to fully understand the magnitude of the benefits that forests provide, it is crucial to understand the full suite of ecosystem services that they offer. A southern Appalachian red spruce-Fraser fir forest was intensively analyzed using a variety of methodologies to determine the nature and quantity of some of these services. Many hypotheses exist regarding the future of these spruce-fir forests, which were heavily disturbed by the non-native balsam wooly adelgid during the 1980s. Direct measurements over the course of a decade assessed these hypotheses and indicate that this forest is recovering structure and function. The forest is ...

MS-based proteomics, which provides a more complete measurement of all the proteins in a cell, has revolutionized a variety of scientific fields, ranging from characterizing proteins expressed by a microorganism to tracking cancer-related biomarkers. Though MS technology has advanced significantly, the analysis of complicated proteomes, such ...
The Life History And Control Of Pityophthorus Juglandis Blackman On Juglans Nigra L. In Eastern Tennessee, 2013 University of Tennessee, Knoxville
The Life History And Control Of Pityophthorus Juglandis Blackman On Juglans Nigra L. In Eastern Tennessee, Katheryne Avery Nix
In the last decade, western states have experienced an increasing mortality rate in Juglans nigra L., black walnut, as a result of the fungal species Geosmithia morbida Kolařík et al. that results in numerous cankers that girdle the branches, resulting in dieback and tree mortality. The only known vector of G. morbida is the walnut twig beetle (WTB), Pityophthorus juglandis Blackman. This newly recognized disease/insect complex has been named Thousand Cankers Disease (TCD) due to the quantity of cankers produced by G. morbida.
Recently, TCD was discovered in the eastern U.S. To limit the spread of TCD in ...
