Alaska Ecosystems Summer Research Program
TEN RESEARCH POSITIONS AVAILABLE IN ALASKA
May - August, 2000

Research projects in laboratories of Terry Chapin and Marilyn Walker
Intended for undergraduates
Applications due March 21, 2000

We are seeking ten enthusiastic undergraduates or recent graduates who are
interested in summer field research in Alaska. The overall objective of
the research program is to understand the ecosystem and global consequences
of potential future changes in arctic vegetation. There are five
separate research projects. In addition to participating in the overall
program research, students will be encouraged to develop their own
individual research project.

  1. Three positions are available to work at the Toolik Lake Research Station
    on the North Slope of the Brooks Range in arctic Alaska and in the boreal
    forest near Fairbanks, Alaska. Two positions go from approximately June 15
    to August 31. The other position will go from approximately June 1 to August
  2. We will be working on two different projects: 1) an experiment to
    examine species effects on community structure and ecosystem carbon and N
    cycling in stable and changing tundra plant communities, and 2) an
    experiment to see how species identity affects nitrogen retention in a
    boreal forest community following fire. In the tundra experiment, we are
    removing key species and functional groups of species in a factorial design
    with nutrient addition, as past experiments have shown that fertilization
    leads to dramatic changes in community structure and ecosystem productivity.
    Students will assist in maintaining the experiment and in collecting litter
    for a decomposition experiment to assess species effects on nutrient supply.
    Toolik Field Station is the focal point for research by about 50 scientists
    who work on a variety of aquatic and terrestrial projects (further
    information available at http://mercury.bio.uaf.edu/~toolik.organizations/).
    In the boreal forest experiment, we are setting up plots in a recently
    burned area where we will seed in or remove different functional groups of
    species to see how species identity affects nitrogen retention. The area was
    treated with a 15N tracer last summer. Students will assist in setting up
    the plots, building boardwalks, and analyzing soil cores for nitrogen
    content. These projects offer the opportunity for students to do comparative
    independent projects between arctic and boreal ecosystems. For more
    information, contact Donie Bret-Harte (syndonia [at] lter.uaf.edu) and Michelle
    Mack (mmack [at] lter.uaf.edu), the people who will be working most closely with
    students on this project.

  3. Two positions are available to work at the Toolik Lake Field Research
    Station on the North Slope of the Brooks Range in arctic Alaska from
    approximately June 1 through August 31. We will be working on the Toolik
    Snowfence Project (part of the International Tundra Experiment network)
    which examines the long term effects of increased snow depth (shortened
    growing season) and increased summer temperatures on the tundra vegetation,
    to asses possible changes that may occur in tundra plant communities due to
    global climate change. There are two snowfence experiment sites which have
    been established since the summer of 1995; one in moist tussock tundra and
    the other in dry heath tundra. There is also a new study site in a natural
    snowbed community which will help explain some of the vegetation changes
    that we are beginning to see at the snowfence sites. At each of these sites
    data on plant phenology, growth, reproductive effort, thaw depth, soil
    moisture, and nutrient cycling are collected, using a variety of techniques.
    In addition, long-term plant community data will be collected at all of the
    snowfence experiment plots in order to asses plant community shifts due to
    the experimental manipulations. Toolik Field Station is the focal point for
    research by about 50 scientists who work on a variety of aquatic and
    terrestrial projects (further information available at
    http://mercury.bio.uaf.edu/~toolik.organizations/). For more information
    contact Andrew Borner (ftapb [at] uaf.edu), the person who will be working most
    closely with students on this project.

  4. Three positions are available to work on the Seward Peninsula in western
    Alaska. The duration of each position will be a maximum of 15 weeks
    (May-July, June-August and July-September), with exact dates somewhat
    flexible. The project will be conducted in Council, a small community about
    70 miles from Nome. Students will be accommodated in a small field camp
    consisting of between 7 and 12 members. The purpose of the research is to
    determine how arctic ecosystems may influence the rate or patterns of
    regional and global climate change. The work focuses on measurements of the
    land surface in different arctic vegetation types close to the arctic
    treeline. Students will participate fully in research activities including
    the program of meteorological and ecophysiological sampling on regular
    basis. One aspect of the program aims to use micrometerological equipment to
    measure water, energy and trace gas exchanges over different ecosystem
    types. Students engaged in this project will assist in the installation and
    maintenance of eddy covariance systems; be responsible for data collection
    from meteorological data loggers; assist in the calibration and use of
    infrared gas analyzers in ecosystem CO2 flux measurements; and participate
    in measurements using the NCAR Integrated Sounding System and tethersonde.
    For this work, experience with meteorological instrumentation, computer
    programming, and electronics would be an advantage. For more information
    about this project contact Jason Beringer (beringer [at] lter.uaf.edu). A second
    aspect of the program focuses on the role of plant functional types in the
    ecosystem and its response to change. This fieldwork complements the
    development of a dynamic vegetation model. Students will help conduct a
    detailed vegetation analysis in a variety of surface types, including
    seasonal measurements of leaf area, biomass, distribution and cover.
    Catharine Copass (ftcdc [at] uaf.edu) is the contact for the vegetation
    sampling work. In addition to the above projects, students will be expected
    to complete individual research projects focused on a topic related to the
    program and their own interests. Further information on this project can be
    found at http://www.lter.uaf.edu/ATLAS/.

  5. One position is available from approximately mid-May to mid-August to
    work on research examining feedbacks between fire regime, vegetation, and
    climate in interior Alaska and Yukon Territory, Canada. This research will
    involve establishing experiments in recently burned forest which examine the
    effects of burn severity, summer temperature, and seed availability on tree
    seedling establishment. We will also be conducting surveys of previously
    burned forest stands of different ages to evaluate post-fire successional
    changes and collect information on how differences in stand composition may
    influence fire regime. Research sites will be located in Alaska and Yukon
    Territory. The student will spend some time in Fairbanks, and will also do
    extensive camping at road-accessible sites between Fairbanks and Whitehorse.
    The student will require a valid passport and driver’s license. Please
    contact Jill Johnstone (ftjfj [at] uaf.edu) for more information on this project.

  6. One position is available to work at the Bonanza Creek LTER site and the
    boreal forests near Fairbanks from approximately June 1st through August
    31st. This research will be examining boreal forest dynamics and black
    spruce distribution, with focus on treeline vegetation distribution and the
    similarities of these forests to tundra ecosystems floristically. The
    student will help in establishing plots, identifying plant species,
    collecting soil and climate data, and in data-base management of existing
    plots and vegetation mapping at the Bonanza Creek site. The student will
    live in Fairbanks, and will require a valid driver’s license. For more
    information please contact Teresa Nettleton (fttkn [at] aurora.uaf.edu). Further
    information about the sites available at
    http://www.lter.uaf.edu/html/site_info.html

Each position pays $1500 per month (before taxes). Travel from your
university to and from the field site will be covered. Class background in
physiological ecology, ecosystem ecology, or meteorology/ climatology and
experience in field or laboratory are preferred. Students must be willing to
work long hours in the field, occasionally under adverse weather conditions.
Competent, careful, emotionally mature, and enthusiastic people desired! We
want the work to be fun as well as intellectually challenging and
aesthetically pleasing. We encourage applications from women and minorities.
