A 31 month post doc-position in Polar invasion ecology is available at the Department of Ecological Science, for the research project entitled ‘Aliens in the polar regions’, funded by the Netherlands Polar Program (NWO). Within this project we aim to unravel the impacts of alien plant establishment on the functioning of terrestrial Arctic ecosystems in a warmer climate. What are the consequences of alien invasions for the primary productivity, nutrient availability and carbon cycling in Arctic ecosystems? In particular the large carbon stocks of sub-arctic tundra are of interest as they have large feedbacks to the global carbon cycle and greenhouse gas induced climate warming. In addition, we aim to establish the role of native species that could facilitate, as ‘invasion engineers’, the establishment of alien species. The candidate will perform growth experiments between native Arctic and invasive species under controlled laboratory conditions as well as under field conditions in the Arctic region (northern Scandinavia and Svalbard). The project will contribute to improve the research and environmental management activities related to alien invasions within the Conservation of Arctic Flora and Fauna. The project will be run in collaboration with prof. P. Convey from the British Antarctic Survey.

Your duties
• Perform growth experiments between invasive and native Arctic vascular plants in order to identify potential success and impacts of invasive species
• Quantify the impact of invasive species on the functioning of Arctic ecosystem processes, such as primary production, carbon and nutrient cycling..
• Quantify the effect of invasive species on the release of soil carbon from deeper soil layers using stable isotopes
• Perform experiments to quantify the role of climate warming on the impact and success of invasive species.
• Identify native ‘invasion engineers’ that could facilitate success of invasive plants.
• Writing of scientific manuscripts at the end of the project..


• PhD in Ecological Sciences or comparable, with relevant research experience.
• Experience with plant ecology under laboratory and field conditions is essential.
• Experience with use of stable isotopes (13C) in experiments is preferred.
• Willingness and ability to work in remote Arctic regions
• Proficiency with statistical approaches and use of R.
• Ability to independently publish in peer reviewed science journals.
• Excellent social skills to work in an interdisciplinary international research team.
• English language proficiency both in speech and in writing.
