The Department of Ecology and Environmental Science at Umeå University, Sweden, invites applicants for two postdoc positions (3 years) focusing on year-round seasonality of plant and microbial carbon and nitrogen cycling in the tundra, and how these are driven by environmental and community variation. The positions are based at the Climate Impacts Research Centre in Abisko, Sweden. Start date 1 July or according to agreement. Application deadline is 27th of May, 2022.

Project description The positions are part of a large interdisciplinary project (https: // kaw.wallenberg.org/en/research/winter-studies-arctic-yield-new- insights-greenhouse-gas-emissions) 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 on the seasonality of the activities of plant and microbial communities, and their synchronization. In the Arctic, climate change is especially pronounced during autumn, winter and spring, which may cause asynchronies of these processes, leading to increased carbon and nitrogen losses and positive climate feedbacks. This large interdisciplinary project will advance basic knowledge of synchronies in 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.

Work tasks We are now inviting applicants for two postdoc-positions within the above project. The holders of the positions will investigate year-round seasonal (a)synchronies in plant and microbial carbon and nitrogen cycling in arctic terrestrial ecosystems, and how these are driven by environmental and community variation.

The project is funded by the Wallenberg Foundation and running 2021-2026. It will benefit from ongoing collaborations between plant ecologists at Umeå University and fungal and microbial ecologists at SLU in Uppsala, and will use techniques from plant ecology, soil molecular microbiology, biogeochemistry (including isotope-based techniques), and up-scaling based on drone technology and satellite imaging. The project will involve a research team of about eleven senior and postdoctoral scientists, four PhD students and two technical staff. Most of the experimental work will be based in the subarctic/alpine tundra and at the research facilities of the Climate Impacts Research Centre and the Abisko Scientific Research Station in northern Sweden.

The hosts will be Dr. Ellen Dorrepaal and Professor Johan Olofsson.

Qualifications To be appointed under the postdoctoral agreement, postdoctoral fellows are required to have completed a doctoral degree or a foreign degree deemed equivalent to a doctoral degree. This qualification requirements must be fulfilled no later than at the time of the appointment decision.

To be appointed under the postdoctoral agreement, priority should be given to candidates who completed their doctoral degree, according to what is stipulated in the paragraph above, no later than three years prior. If there are special reasons, candidates who completed their doctoral degree prior to that may also be eligible. Special reasons include absence due to illness, parental leave, appointments of trust in trade union organisations, military service, or similar circumstances, as well as clinical practice or other forms of appointment/assignment relevant to the subject area. Postdoctoral fellows who are to teach or supervise must have taken relevant courses in teaching and learning in higher education.

We are looking for two persons with interest in carbon and nitrogen cycling in arctic terrestrial ecosystems. PhD degree must be in ecology, biogeochemistry, physical geography, or other relevant field.

Additional requirements are good knowledge of techniques used to study ecosystem carbon or nitrogen cycling and demonstrated experience of ecological fieldwork. The successful applicants should further have a track record of scientific publication in a relevant field, excellent skills in scientific communication in English, creativity, power of initiative, independence, good interpersonal skills and ability to collaborate.

Strong merits for these positions are knowledge of arctic terrestrial ecosystems, terrestrial biogeochemistry, experience in the use of stable isotopes and statistics, experience with outdoor activities under arctic winter conditions, and a driving license for cars. Evaluations will be based on the application, references, and interviews.
