Post-Doctoral Research Opportunities at the U.S. Geological Survey 
Rocky Mountain Geographic Science Center, Denver, Colorado: 
Mapping, Valuation, and Optimization of Ecosystem Service Flows. Research 
Advisors, Dr. Darius Semmens ([email protected]), Dr. Jay Diffendorfer, 
Dr. Todd Hawbaker, and Dr. Lynne Koontz. This opportunity focuses on 
examining spatial patterns of ES provisioning and consumption, and 
identifying land management strategies that optimize service provisioning 
and the sustainable economic value derived from public lands. The fellow 
will a) expand and improve existing methods, or develop new methods for 
mapping and valuing ES flows, and b) facilitate trade-off analyses by 
utilizing stakeholder constraints to identify optimal land management 
strategies. A number of potential project sites exist, and applicants need 
to consult with the research advisors to identify site(s) best suited to 
their interests.  Research will be conducted in close cooperation with 
existing collaborative ES research partnerships within the USGS, other 
federal agencies, county government, and local universities. 
Impacts of Mountain Pine Beetles on Carbon Sequestration in South Rocky 
Mountain Forests. Research Advisors, Dr. Todd Hawbaker (
[email protected]), Dr. Jenny Briggs, Dr. Steve Garman, and Dr. Dave 
Clow.  We seek candidates to conduct new research integrating existing 
field and remotely sensed data with biogeochemical and ecosystem 
simulation models to quantify long-term changes in carbon stocks and 
fluxes in response to Mountain Pine Beetle infestations in the southern 
Rocky Mountains.  Candidates will have the flexibility to pursue research 
according to their specific interests and expertise.  However, we expect 
candidates to have demonstrated expertise in one or more areas including 
modeling insect outbreaks, vegetation dynamics, hydrological and 
biogeochemical cycling.  Experience working with remotely sensed and 
geospatial data, and excellent writing and communication skills are 
required. 
Quantitative Methods to Assess the Impacts of Urban Growth on BLM Lands in 
the Western United States. Research Advisors, Dr. Steve Garman (
[email protected]) and Dr. Jay Diffendorfer. Researchers at RMGSC are 
involved in urban-growth modeling in support of BLM resource management 
plans in Grand Junction, CO, with a long-term goal of developing a 
comprehensive modeling framework to evaluate interactions among community 
growth, federal land-use decisions, and biophysical impacts. Expansion of 
human population has been linked to an increase in spread of exotic plant 
species, and to increased recreational demands on public lands. 
Implementing land-use designs that reduce or buffer against impacts of 
these two stressors, among others, is a key goal of BLM. Two research 
areas in need of future development are predicting biophysical changes due 
to exotic plant invasion, and due to increased recreational use.

About us:  The USGS Rocky Mountain Geographic Science Center (RMGSC) is 
one of four field centers in the Geography Discipline of USGS.  Staffed 
with  7 PhD scientists, 60+ researchers, and support staff, RMGSC conducts 
a broad array geographic research and applies geospatial data and models 
to monitor and evaluate the land surface and the interactions between 
humans and the environment. We are an energetic, collaborative group of 
researchers who interact with academic institutions, other federal 
agencies, and nonprofit institutions.
Mendenhall PostDoctoral Research Opportunities at the U.S. Geological 
Survey - Background Information 
The U.S. Geological Survey (USGS) began the Mendenhall Postdoctoral 
Research Fellowship Program (now called Mendenhall Research Fellowship 
Program) in 2001 in honor of Walter C. Mendenhall, the fifth Director of 
the USGS.  The Mendenhall Program provides an opportunity for recent PhD 
graduates (within five years since completion of the doctoral degree) to 
conduct concentrated research in association with selected members of the 
USGS professional staff.  The Program is intended to provide research 
fellows with experiences that enhance their personal scientific skills and 
accomplishments.  Through the Mendenhall Program the USGS acquires current 
expertise to assist in the advancement of its scientific goals. 

To date, over 120 Mendenhall Fellows have joined the USGS.  Mendenhall 
Fellowships are 2-year appointments with a competitive salary and benefits 
package.  Mendenhall Fellows are also granted project expense funds 
appropriate to the scope of research to be conducted.  Postdoctoral 
research projects under this program have spanned a wide range of 
scientific topics of interest and relevance to the mission of the USGS. 
 For additional information, please consult the Project Profiles section 
of the Mendenhall Program web site at the following URL: 
http://geology.usgs.gov/postdoc/ 

What is it like to be a USGS Mendenhall Fellow?  Check out the FAQ section 
of the program web site for some very informative quotes from previous 
Mendenhall Fellows.  Also, another way, of course, is to find out directly 
from a Fellow -- Project Profiles contain their contact information.   

The next round of research opportunities (FY-11 Fellowships) were 
announced in July 2009.  The application closing date is November 9, 2009. 
 The earliest start date for the FY-11 Fellowships is October 2010.
