Investigating The Effect Of The ‘‘Land Between The Lakes’’ On Storm Patterns, Joshua D. Durkee, Ahmed M. Degu, Faisal Hossain, Rezaul Mahmood, Jesse Winchester, Themis Chronis Jan 2014

Investigating The Effect Of The ‘‘Land Between The Lakes’’ On Storm Patterns, Joshua D. Durkee, Ahmed M. Degu, Faisal Hossain, Rezaul Mahmood, Jesse Winchester, Themis Chronis

High Plains Regional Climate Center: Staff Publications

The artificially created region around the ‘‘Land between the Lakes’’ (LBL) in Kentucky represents unique land use and land cover (LULC) heterogeneities. Over a distance of 100 km, the LULC comprises artificially created open water bodies (i.e., two parallel large run-on-river dams separated by the LBL), mountainous terrain, forest cover, and extensive agricultural land. Such heterogeneities increase (decrease) moisture supply and sensible heat, resulting in a differential air mass boundary that helps to initiate (inhibit) convection. Hence, the LBL can potentially modify precipitation formation. Historical anecdotes reveal a tendency for storms to dissipate or reintensify near the LBL. The specific …

Identifying Priority Conservation Areas For The American Burying Beetle, Nicrophorus Americanus (Coleoptera: Silphidae), A Habitat Generalist, Jessica D. Jurzenski, Christopher F. Jorgensen, Andy Bishop, Roger Grosse, John Riens, W. Wyatt Hoback

United States Fish and Wildlife Service: Publications

Conservation efforts leading to the recovery of the federally endangered American burying beetle (ABB), Nicrophorus americanus Olivier, have been challenging because of the unknown causes of its decline, difficulty in establishing habitat requirements, and unclear population distribution across the species’ range. Extant populations of this widespread generalist species occur in broadly separated regions of North America with varying habitat characteristics. A habitat suitability model for ABB in the Nebraska Sandhills was developed over the course of 3 years resulting in a final cross-validated spatial model. The succession of models from 2009 to 2011 indicated that most of the predictive variables …


Development And Evaluation Of High Resolution Simulation Tools To Improve Fire Weather Forecasts, Brian K. Lamb, Jason M. Forthofer, Peter R. Robichaud Jan 2014

Development And Evaluation Of High Resolution Simulation Tools To Improve Fire Weather Forecasts, Brian K. Lamb, Jason M. Forthofer, Peter R. Robichaud

Joint Fire Science Program Research Project Reports

Fire weather forecasts rely on numerical weather simulations where the grid size is 4 km x 4 km or larger. In areas of complex terrain, this model resolution will not capture the details of wind flows associated with complicated topography. Wind channeling in valleys, wind speed-up over mountains and ridges, and enhanced turbulence associated with rough terrain and tall forest canopies are poorly represented in current weather model applications. A number of numerical wind flow models have been developed for simulating winds at high resolution; however, there are limited observational data available at the spatial scales appropriate for evaluating these …


Exploring How Deliberation On Scientific Information Shapes Stakeholder Perceptions Of Forest Management And Climate Change, Troy E. Hall, Jarod J. Blades Jan 2014

Exploring How Deliberation On Scientific Information Shapes Stakeholder Perceptions Of Forest Management And Climate Change, Troy E. Hall, Jarod J. Blades

Joint Fire Science Program Research Project Reports

Climate change has resulted in rapid biophysical changes in forests of the western U.S. and has prompted the need for an increased understanding of potential impacts and adaption measures. Land managers, policy makers, and community officials lack locally relevant climate change science and are urgently calling for research to inform management decisions. Nevertheless, a substantial disconnect remains between emerging scientific information and its application in management decisions. Effective action depends on understanding regional and local implications of climate change and open, reasoned discussions about current research and potential mitigation actions among researchers, land managers, and other stakeholders. Boundary objects have …


Fire Effects On Seedling Establishment Success Across Treeline: Implications For Future Tree Migration And Flammability In A Changing Climate, F. S. Chapin Iii, Teresa N. Hollingsworth, Rebecca E. Hewitt Jan 2014

Fire Effects On Seedling Establishment Success Across Treeline: Implications For Future Tree Migration And Flammability In A Changing Climate, F. S. Chapin Iii, Teresa N. Hollingsworth, Rebecca E. Hewitt

Joint Fire Science Program Research Project Reports

Understanding the complex mechanisms controlling treeline advance or retreat in the arctic and subarctic has important implications for projecting ecosystem response to changes in climate. Changes in landcover due to a treeline biome shift would alter climate feedbacks (carbon storage and energy exchange), ecosystem services such as wildlife and berry habitat, and landscape flammability. Wildfire frequency and extent has increased in the last half-century in the boreal forest and tundra in response to warmer weather and lower precipitation. Invasion of tundra by trees may be facilitated by wildfire disturbance, which exposes new seedbeds, increases nutrient availability immediately post-fire, and creates …

Winter Wind Chill Climatology For The High Plains Region, Holly B. Lussenden, Natalie A. Umphlett, Martha D. Shulski, Daniel Ebert Jan 2014

Winter Wind Chill Climatology For The High Plains Region, Holly B. Lussenden, Natalie A. Umphlett, Martha D. Shulski, Daniel Ebert

High Plains Regional Climate Center: Staff Publications

During the winter months in the High Plains region of the United States, wind chill temperatures can reach dangerous levels for humans and animals. Knowing the frequency in which extreme wind chill temperatures occur could help forecasters know when to issue wind chill advisories and also the general public understand just how rare, or common, certain wind chill temperatures are. A climatology spanning a 37-year period was created using data from 57 stations in and around the plains portion of the High Plains region from the Integrated Surface Hourly Database at National Climatic Data Center (NCDC). These climatologies were completed …

Quantitative Assessments Of Municipal Waste Management Systems: Using Different Indicators To Compare And Rank Programs In New York State, Krista L. Greene, David J. Tonjes

Technology & Society Faculty Publications

The primary objective of waste management technologies and policies in theUnited Statesis to reduce the harmful environmental impacts of waste, particularly those relating to energy consumption and climate change. Performance indicators are frequently used to evaluate the environmental quality of municipal waste systems, as well as to compare and rank programs relative to each other in terms of environmental performance. However, there currently is no consensus on the best indicator for performing these environmental evaluations. The purpose of this study is to examine the common performance indicators used to assess the environmental benefits of municipal waste systems to determine if …


A Review Of The Hyporheic Zone, Stream Restoration, And Means To Enhance Denitrification, Leanne Merill, David J. Tonjes Jan 2014

A Review Of The Hyporheic Zone, Stream Restoration, And Means To Enhance Denitrification, Leanne Merill, David J. Tonjes

Technology & Society Faculty Publications

The hyporheic zone is the subsurface area below and adjacent to a stream where groundwater mixes with stream water, through vertical, lateral, and longitudinal flows. The hyporheic zone connects the stream to uplands and other terrestrial environments. It is a zone of distinct faunal communities, high biological diversity and ecological complexity, and is the site of chemical processing and transformations of ground- and stream waters. The hyporheic zone is important to the overall ecosystem ecology of the stream, and it can influence stream water chemistry. Flows, reactions, and biota in the hyporheic zone are heterogeneous and patchy, making it difficult …

Conflict Translates Environmental And Social Risk Into Business Costs, Daniel M. Franks, Rachel Davis, Anthony J. Bebbington, Saleem H. Ali, Deanna Kemp, Martin Scurrah Jan 2014

Conflict Translates Environmental And Social Risk Into Business Costs, Daniel M. Franks, Rachel Davis, Anthony J. Bebbington, Saleem H. Ali, Deanna Kemp, Martin Scurrah

Geography

Sustainability science has grown as a field of inquiry, but has said little about the role of large-scale private sector actors in socio-ecological systems change. However, the shaping of global trends and transitions depends greatly on the private sector and its development impact. Market-based and command-and-control policy instruments have, along with corporate citizenship, been the predominant means for bringing sustainable development priorities into private sector decision-making. This research identifies conflict as a further means through which environmental and social risks are translated into business costs and decision making. Through in-depth interviews with finance, legal, and sustainability professionals in the extractive …


Integrating Societal Perspectives And Values For Improved Stewardship Of A Coastal Ecosystem Engineer, Steven B. Scyphers, J. Steven Picou, Robert D. Brumbaugh, Sean P. Powers Jan 2014

Integrating Societal Perspectives And Values For Improved Stewardship Of A Coastal Ecosystem Engineer, Steven B. Scyphers, J. Steven Picou, Robert D. Brumbaugh, Sean P. Powers

University Faculty and Staff Publications

Oyster reefs provide coastal societies with a vast array of ecosystem services, but are also destructively harvested as an economically and culturally important fishery resource, exemplifying a complex social-ecological system (SES). Historically, societal demand for oysters has led to destructive and unsustainable levels of harvest, which coupled with multiple other stressors has placed oyster reefs among the most globally imperiled coastal habitats. However, more recent studies have demonstrated that large-scale restoration is possible and that healthy oyster populations can be sustained with effective governance and stewardship. However, both of these require significant societal support or financial investment. In our study, …

Las Raíces De La Deforestación En El Departamento Pando, Jeremy Levine-Drizin Oct 2013

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 …

Vulnerability, Environmental Security, And Adaptation Awareness In Samoa, Katie Williams

Independent Study Project (ISP) Collection

Climate change remains a prevalent problem for today’s international community, particularly for Pacific Island countries. This study examines the current influence of climate change on Samoa by looking at the three tenets of vulnerability: exposure, sensitivity, and adaptive capacity. These aspects of climatic change correlate and build off one another, ultimately elucidating the basic vulnerability of any given region. It also analyzes how environmentally secure Samoa is and will be, using Thomas Homer- Dixon’s theory on climate change and conflict. Finally, this paper seeks to outline the current system of adaptation awareness that exists between government, community and foreign aid …

Independent Study Project (ISP) Collection

Home to the second largest reserves of petroleum in the world, Latin America will prove to play an important role in the international energy market throughout the 21st century. Today, Argentina and Brazil in particular boast extensive quantities of nonconventional natural gas and petroleum reserves in the shale beneath the Vaca Muerta oil fields and the offshore wells of the Campos and Santos basins, respectively. Through the direction of their nationally-held oil companies (NOCs), YPF and Petrobras, the States of Argentina and Brazil have sought to exert their sovereignty over the presence of their hydrocarbon reserves. Whether financed through the …
