NREL NEWS NOTES
NATURAL RESOURCE ECOLOGY LABORATORY
COLORADO STATE UNIVERSITY
No. 17 April & May 1995
Featuring: Elisabeth Holland - NCAR/ACD & NREL
Beth Holland is a member of the Global Modeling Group of the Atmospheric
Chemistry Division of the National Center for Atmospheric Research
(NCAR) and a research scientist affiliated with NREL. Beth is currently
working on bio-atmospheric nitrogen deposition on terrestrial carbon
uptake and the importance of NO emitted from soils to atmospheric
chemistry. Some of her papers are listed in the NREL News Notes Publications
Section. Beth was recently awarded the Directorship of a NATO Advanced
Study Institute on "Soils and Global Change: Trace Gases, the Carbon
Cycle and Hydrology" to be held at the Chateau de Bonas, France, June
16-17, 1997. As she puts it, "the NATO ASI and my affiliations with
NREL, CSU and CU give me all sorts of opportunities to interact with
students which I love."
Beth is a true NREL product. She started working at NREL with
Dave Coleman and Bill Parton in 1980 as an undergraduate research
assistant on a belowground project. Her first research project was
on "Dew formation influences on soil respiration." Since 1982 when
Beth received her B.S. in Zoology at CSU, she has gone on to lead
a varied and successful research career. She did research on interactions
between litter placement, bacterial vs. fungal decomposition and
soil organic matter stabilization for her MS in Agronomy with Dave
Coleman, Ken Doxtader and Bill Parton (1985). In 1988, Beth received
her Ph.D. in Rangeland Ecosystem Science, working on how herbivory
influences on plant carbon allocation affected nitrogen cycling
as part of the Wind Cave Project with Jim Detling. She still credits
Vern Cole and his argumentative style for providing the training
and practice needed for persistence in science.
In September 1988, Beth left NREL for a Stanford post-doctoral
fellowship with Hal Mooney and Peter Vitousek. Stanford was an amazing
contrast with NREL. Stanford discussions were intense and required
an instant in depth analyses of the issues while scientific discussions
at NREL could go on for weeks. At Stanford, Beth worked on nitrogen
cycling in a serpentine grassland and began her involvement with
the NSF-funded Jasper Ridge CO2 project with Chris Field, Terry
Chapin and Hal Mooney. In late 1989, Beth returned to Colorado to
work at NCAR.
Two aspects of the NREL experience have served Beth particularly
well: (1) the emphasis on modeling and truly quantitative analysis
and (2) the willingness to tackle interdisciplinary problems with
the critical thought and in- depth analysis that they deserve.
We are pleased to highlight another of our outstanding scientists.
Dave Swift was presented an award for "Outstanding Professor 1995-1996"
by the Rangeland Ecosystem Science Department. Congratulations, David,
Nice Job!!
Diana Freckman has been awarded a University of California - Davis,
Bodega Marine Laboratory Distinguished Research Fellowship for summer
1988. Recipients of this fellowship are scientists of outstanding
accomplishment and reputation.
Jim Detling returned from a sabbatical at CSIRO's National Rangeland
Program in Canberra, Australia on April 27. Welcome home, Jim!
David Valentine has accepted a tenure track position in Forest
Soils in the School of Agriculture and Land Resources Management
at the University of Alaska, Fairbanks. This will enable him to
stay in the same town as his daughter, Kirsten, who will be moving
to Fairbanks this fall. The University of Oklahoma understood the
situation and has graciously released Dave from his commitment there
this fall. Dave and By will be leaving for Alaska around August
1 and his job begins September 1, 1996. His time will be split,
60% research, 30% teaching, and 10% service. He will be teaching
2 courses per year, one in undergraduate forest soils (junior level)
and the other a graduate course of his choice. Dave and By will
indeed be missed at NREL and we all wish you a great deal of success
in your new job!
Geneva Chong recently returned from Honduras where she worked
with the Partnership for Biodiversity in the Mosquitia (or Mosquito
Coast). She evaluated a butterfly farm in the Rio Platano Biosphere
Reserve that was started by the Peace Corps, San Diego Zoological
Society and MOPAWI (a Honduran non-governmental organization). She
had a fantastic time, and hopes her recommendations will help the
farm meet its goals of ecological and economic sustainability.
The PROGRAM and ABSTRACTS for the 1996 combined Ecological Society
of America, Society of Conservation Biology, Association for Tropical
Biology, American Association of Naturalists, and International
Society of Ecological Modeling Annual Meeting were sent to Allen
Press for printing and publication. A million thanks go out to the
NREL Production staff: Becky Techau, Melissa Baker, Amy Whitehead,

Diana Freckman and Bob Niles received word that their proposal titled
"Nematode Biodiversity in Ecosystems Stressed by Extremes of Temperature"
was funded by NSF/DEB for $100,000. This is an 18 month project which
is to conduct an extensive survey of soil nematodes inhabiting ecosystems
in the western United States stressed areas. Nematodes will be surveyed
from the Chihuahuan Desert [Jornada Long Term Ecological Research
(LTER) site] and the transition zone of the Chihuahuan Desert, Great
Basin, and shortgrass steppe (Sevilleta LTER). Nematodes, their descriptions,

U.S. Department of Agriculture
Deb Coffin (NREL and Rangeland Ecosystem Sciences) and George Beck
(Plant Pathology and Weed Science) were recently funded by the USDA/
National Research Initiative Competitive Grants Program for the project
titled "Invasion of Rangeland by Aggressive Perennial Weeds: Ecology
and Management." The goal of the project is to predict the environmental
conditions under which the aggressive, perennial weed, Russian knapweed,
maintains its dominance through time and the conditions where native
vegetation returns to dominance as a result of succession. The project
will use experimental studies and simulation modeling to evaluate
the short- and long-term effects of soil texture and precipitation
on invasion dynamics of Russian knapweed in rangelands of Colorado.
The three-year project will start July 1, 1996 and was funded at $387,500.
Diana Freckman was funded by USDA/Research, Education and Economics,
for "Evaluation Study Proposal." The 1-year grant will consist of
2 meetings: 1 at NREL and 1 at the Smithsonian Institute and will
bring administrators of USDA, scientists and economists in a think-tank
for The Bioregional Research Meeting.

RESEARCH ASSOCIATE
(Field Technician - Ultraviolet Radiation Monitoring Network)
The USDA sponsored Ultraviolet Radiation Monitoring Network at
Colorado State University is seeking an individual to install, troubleshoot
and repair instrumentation; train operators; and assist in the coordination
of the network's field activities. The selected candidate will be
expected to become familiar with all aspects of the monitoring program
including siting criteria, field procedures, equipment operation
and maintenance, data management and general program objectives.
Responsibilities will include the acquisition of data telemetered
from the monitoring stations, report preparation, and preparation
of special data summaries. The field technician will be required
to make independent decisions on instrument siting and operation
and make both written and verbal presentations to university and
federal agency scientists. Considerable travel will be necessary
to service sites across the United States.
The network began operation in 1993 and presently measures ultraviolet
irradiance in 16 states with both broadband and Multi-Filter Rotating
Shadowband Radiometers (MFRSR). The position will support the network's
planned expansion to 30 sites and its planned addition of instrumentation
to existing sites.
The candidate must possess a B.S/B.A. degree in a physical science
such as physics, astronomy, meteorology, geology, etc with appropriate
experience. Demonstrated knowledge of electronic instrumentation
and repair, positional astronomy and optical measurement principles,
meteorological siting principles and previous experience as a field
technician is highly desirable. Computer experience is essential.
Programming experience, especially in a Unix environment is also
desirable. Funding of the position is dependent upon continued federal
