<div class="">The three positions are part of a large
interdisciplinary project that aims to understand and quantify
how processes during the arctic winter may be decisive for
overall feedbacks from arctic tundra to the global climate.
Arctic ecosystems store large amounts of organic carbon in
plants and soil. Uptake of carbon by arctic plants is
strongly limited by their access to nutrients, especially
nitrogen, due to competition by microbes. Year-round carbon and
nitrogen balances thus depend the activities of plant and
microbial communities and their seasonality. This
interdisciplinary project will involve a research team of about
eleven senior and postdoctoral scientists, four PhD students and
two technical staff. Together, we will advance basic knowledge
of plant and microbial activities during the cold season. The
project will further assess the environmental drivers and
community traits that may be used to up-scale and predict
effects of asynchronies on year-round carbon and nitrogen
balances of tundra. Position 1 and 2 will be based in Abisko
(with course work in Umeå), position 3 in Umeå (with fieldwork
in Abisko). More information can be found via the links above.
We welcome all applications!<br>
