[ECOLOG-L] Graduate and Postgraduate Assistantships: Climate controls on terrestrial-to-aquatic biogeochemical fluxes in boreal forest watersheds

A postdoctoral research position and three graduate assistantships are available for keen and motivated
students interested in research and training centered around understanding the impact of climate
change on boreal forest landscape biogeochemistry. These positions are available as part of a new
NSERC-Strategic Partnership Project focused on the Newfoundland and Labrador Boreal Ecosystem
Latitudinal Transect (NL-BELT; http://ift.tt/1GTUF6k) and made up of foreign collaborators,
provincial and Canadian Forest Service partners as well as Memorial University researchers in Earth
Sciences and Chemistry. The project is focused on exploiting the established NL-BELT which consists
of four large watersheds located in western Newfoundland and southern Labrador to isolate the
potential impact of predicted increases in temperature and precipitation in the coming century while
maintaining an ability to apply the results to intact boreal forest ecosystems and their watersheds. Our
team has been conducting investigations of soils and stream water along the NL-BELT and combining
these with manipulative warming experiments to develop biogeochemical indicators of soil responses to
increasing temperature. The increased ecosystem C fluxes with climate warming established along this
transect appears to occur without significant changes to soil C stocks, however, they suggest important
changes relevant to the terrestrial-to-aquatic flux of materials in these landscapes. It is anticipated that
the new postdoctoral researcher, MSc and two PhD students joining the Biogeochemistry of Boreal
Ecosystem Research Group (BBERG; http://ift.tt/1WNA1qd) will
focus on the following areas within this boreal biome climate change context:
1. Fate and geochemistry of dissolved organic matter in podzolic mineral soil horizons.
2. Biogeochemistry of organic matter through the terrestrial-to-aquatic interface.
3. Nutrient biogeochemistry of the terrestrial-to-aquatic interface.
4. Impacts of hydrology on soil respiratory responses.

Experience with aquatic or soil biogeochemistry, organic geochemistry, and/or environmental chemistry
particularly will be important. All applicants should have a demonstrated background of experience in
biogeochemistry, environmental chemistry, ecosystem ecology or hydrogeochemistry. Applicants should
be willing and able to conduct field research at remote study sites for weeks at a time.

These positions are all available as early as January 1, 2016. The graduate assistantships can be in
either the Department of Earth Sciences or the Environmental Sciences Graduate Programs at Memorial
University (http://www.mun.ca/) where program start dates are in May or September. Memorial is the
largest university in Atlantic Canada. As the province’s only university, Memorial plays an integral role in
the educational life of Newfoundland and Labrador (http://ift.tt/1r7XTXn). Offering a
diverse set of undergraduate and graduate programs for approximately 18,000 students, Memorial
provides a distinctive and stimulating environment for learning in St. John’s
(http://ift.tt/1LFTBCl), a very safe, friendly city with great historical charm, a vibrant
cultural life, and easy access to a wide range of outdoor activities.

Please check the BBERG website (http://ift.tt/1WNA1qd) for
more information and group contacts, and direct further inquires or send applications, including letter of
interest and detailed curriculum vitae (including contact information for 3 references), to:

Dr. Susan Ziegler
Canada Research Chair in Environmental Science
Department of Earth Sciences
Memorial University
St. John’s, NL A1B 3X5

Review of applications will commence immediately and will continue until positions are filled.
