NRM 101 - Natural Resources Conservation & Policy
NRM 290 - Resource Management at High Latitudes
NRM 365 - Principles of Outdoor Recreation Management
NRM 469/669 - Survery Research in Natural Resources Management

Research Interests:

• Human dimensions of natural resource management
• Quantitative survey research methods
• Outcomes-Focused Management
• Recreation planning
• Natural resource based tourism

Dr. Fix’s recent research has focused on advancing the methodology of applying Outcomes-Focused Management to land managed by the USDI Bureau of Land Management.

Current research programs:

• Outcomes-focused management studies for the USDI Bureau of Land Management in Alaska.   This research program assesses the outcomes desired from recreation taking place on lands managed by the BLM Fairbanks District Office.   The information from the studies will be utilized when the BLM develops Resource Management Plans for those areas.
• Outcomes-Focused Management field guide.   This project will develop a BLM manual for their staff who need to apply Outcomes-Focused Management as part of the recreation planning process.   The manual will be adopted at the national level within the BLM.
• Connecting to communities.   This project will assist the BLM, Fairbanks District Office in implementing their new recreation strategy that requires increased attention to the health and economic needs of local communities.  
• Sport Hunting in Noatak National Preserve .  This project assists the National Park Service in addressing conflict between non-local hunters and local subsistence hunters in the Noatak National Preserve.  Non-local sport hunters were surveyed and asked their perceptions of the hunt, conflict, and potential management actions.

Examples of research support:

• "Alaska Resident Statistics Program", AK Dept of Transportation, USDA Forest Service, USDI National Park Service, Bureau of Land Management, $60,500, 2003 - present.
• "Visitor Preferences for Interpretation at Wrangell - St. Elias N.P.", USDI National Park Service, $10,000, 2004.

I received my undergraduate academic training in India, and graduate academic training in India and the U.S.A. My current research is focused on improving the understanding of rapidly evolving permafrost dynamics in Alaska with an ultimate goal of predicting the response of permafrost to climate change, and its effect on the Arctic systems. I use a variety of techniques to study the complex permafrost dynamics that range from detailed ground observations to modeling using information derived from remotely sensed images. My research is vital to address some of the urgent climate change issues affecting Alaskan land, water and people through changes in permafrost such as dramatic changes in surface hydrology, vegetation, forest fires, and wildlife habitats. These changes are not only affecting Arctic environment but also the subsistence resources and subsistence lifestyle of Alaskans.

Research interests:

• Vulnerability and adaptation of northern communities to climate change. Communicating scientific information to inform planning and decision making in climate change adaptation and natural resource management. Human dimensions of global change in the arctic and northern latitudes.  Interdisciplinary assessment of ecosystem services related to global change and mixed subsistence economies in rural Alaska.

Research interests:

Dr. Valentine's broad research interest is in ecosystem ecology, biogeochemistry, and element cycling in northern ecosystems. His past research focused on the role of soils in forests, grasslands, and wetlands in generating or consuming trace gasses, especially carbon dioxide and methane, that influence Earth's climate. His recent research has focused on the effects of wildfire and moisture stress on soil respiration and carbon balance. He teaches courses in soils, nutrient cycling, sustainability, environmental ethics, and environmental decision making based on integrating the major foundations of natural resource management: natural sciences, economics, human values and behaviors, ethics, and policy.

Current research programs:

1) Bonanza Creek LTER: effects of moisture stress on soil respiration and C balance

2) Bonanza Creek LTER: longitudinal evaluation of soil properties along two successional chronosequences

3) Bonanza Creek LTER: mapping soil properties of the university forest as part of a periodic forest inventory
