The department of Arctic and Marine Biology at UiT, The Arctic University of Norway is seeking a postdoctoral researcher to join our research team to study the ecology of methane cycling microorganisms in Arctic permafrost ecosystems. The Postdoc will be accompanied by two PhD students in a new project, 'Cells in the Cold', starting up in August 2018.
A complex yet fragile network of cold adapted microbial cells modulates methane emissions from Arctic permafrost ecosystems on land and in the sub-seabed, which represent the largest and most potent greenhouse gas sources in the warming Arctic. To understand the development of complex methane cycling microbial ecosystems in a changing environment it is necessary to probe different biological levels of organization, from genes to metabolisms and ecosystem level processes.
We aim to understand the nature of changes in microbial ecosystem operation after alteration in temperatures, hydrology, soil/sediment chemistry including substrate availability and to identify the speed of these adaptations.
We will combine field and laboratory experiments, investigating the link between gas fluxes and the microbial metabolic networks mapped by metabolomics and metagenomics/-transcriptomics to test hypotheses that address the central concepts of ecosystem function and change.
Overall, two ecosystem types will be studied in the project.
Methane oxidizing bacterial communities in Arctic ocean sub-seabed methane seeps.
Anoxic decomposition of organic matter and methane oxidation in Arctic peat soils.
In the project, samples will be collected from several locations including Ny-Ålesund Svalbard, Northern Norway, Arctic Canada, and Methane-seep sediments in the Barents Sea/Arctic Ocean.
Within this framework, the focus area will be detailed together with the hired postdoc. It is expected that the applicant shortly summarizes his/her interests and abilities related to the project topics mentioned and documents any relevant skills.
PhD in Microbial/molecular Ecology, Microbiology, Biogeochemistry or related field. A strong documented background in high throughput sequence analysis is a requirement to apply. Experience in statistical analyses, modeling, metabolomics, experimental microbiology/microbial ecology is considered a substantial advantage.
