*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;
https://www.esd.mun.ca/nl-belt/) 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://www.mun.ca/earthsciences/Our_People/Faculty/Ziegler/) 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

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://www.newfoundlandlabrador.com). 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://www.stjohns.ca/visiting-our-city), 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://www.mun.ca/earthsciences/Our_People/Faculty/Ziegler/) 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:
