GRADUATE RESEARCH ASSISTANTSHIP AND POST DOCTORAL POSITIONS:

GRADUATE RESEARCH ASSISTANTSHIP

Candidates for a PhD level graduate research assistantship are being sought
to undertake research within a multidisciplinary, collaborative forest
research program in Maine, USA.  The program involves research personnel
from the University of Maine, USDA Forest Service, Cornell University, The
Woods Hole Research Center, and NASA Goddard Space Flight Center.  Program
co-leaders are S. M. Goltz (University of Maine) and D. Y. Hollinger (USDA
Forest Service).  Interactive, correlative projects within this program
include "Regionalizing the Harvard Forest Long-Term Flux Measurements:
Complementary Studies from Howland, Maine", "Patch and Regional Scale
Studies of Forest Carbon Exchange", and "Study of the Distribution of
Sources and Sinks of Biogenic Gas Fluxes in Boreal Forest Venues" supported
by the National Institute of Global Ecological Change, National Science
Foundation, and NASA, respectively.  Research of the successful candidate
will focus on understanding the mechanisms responsible for the regulation
of forest carbon exchange and storage.  The field research venue about 50
km north of Bangor, Maine encompasses natural stands in a boreal-northern
hardwood transitional forest consisting of hemlock-spruce-fir, aspen-birch,
and hemlock-hardwood mixtures.  Topographically, the region varies from
flat to gently rolling, with a maximum elevation change of less than 68 m.
Due to the region's glacial history, soil drainage classes within a small
area may vary widely, from well drained to poorly drained.  Consequently,
an elaborate patchwork of forest communities has developed, supporting
exceptional local species diversity.  Experimental towers equipped with 1-D
and 3-D sonic anemometers, fast response H2O and CO2 analyzers as well as
ancillary radiation, temperature, and humidity sensors are available.  In
addition, a CO2 profiling system is in place.  Candidates with backgrounds
in environmental physics, micrometeorology, or soil physics are encouraged
to apply.  Experience with mass and energy exchange measurements including
eddy covariance measurement methods is highly desirable.

POST DOCTORAL POSITION

We expect an Ecophysiology Post Doctoral position to be available for
start 1 February 1996.  Research will be in the interdisciplinary area  of
canopy-atmosphere gas exchange and will center around activities at  the
Howland research site described above.  Candidates should have a strong
background in one or more of the following areas; leaf gas exchange, canopy
ecophysiology, canopy flux measurement, micrometeorology, stable isotope
studies, or photosynthesis modeling.  This is a 2-3 year position  based in
Durham, NH.
