Post Details: Post-doctoral Research Fellow in Terrestrial Ecosystem Science (specifically, Plant-Soil Interactions): Fixed term contract for 42 months. The closing date for applications is midnight on Monday 17 April 2023. Interviews dates are to be confirmed. There is an expectation that work will be undertaken in the UK. For the purposes of sponsorship, this is a postdoctoral role under SOC code 2119.
The University of Stirling recognises that a diverse workforce benefits and enriches the work, learning and research experiences of the entire campus and greater community. We are committed to removing barriers and welcome applications from those who would contribute to further diversification of our staff and ensure that equality, diversity and inclusion is woven into the substance of the role. We strongly encourage applications from people from diverse backgrounds including gender, identity, race, age, class, and ethnicity.
Applications are invited for a Postdoctoral Research Fellow (PDRF) to work with Professor Philip Wookey for a period of up to 42 months on the ‘MYCONET’ project. This NERC funded project aims to understand how the highly organic soils of northern latitudes will respond to increased abundance of trees and woody shrubs. MYCONET will focus on the role of the ‘mycorrhizosphere’ (the soil and organisms directly influenced by roots and their mycorrhizal fungi) in determining the carbon balance of these globally important soil carbon stores.
The overarching hypothesis of MYCONET is that associated changes in the mycorrhizosphere with tree and shrub establishment could, paradoxically, result in net losses, rather than gains, of soil carbon (C) over timescales of relevance to the Climate Emergency: This would represent a ‘positive feedback’ on climate change.
The position will be based in the Department of Biological and Environmental Sciences at the University of Stirling (UK). This is a collaborative project involving Co-Investigators Dr Lorna Street (University of Edinburgh), Drs Thomas Parker and Andy Taylor (James Hutton Research Institute (JHI), Aberdeen) and project partners Dr Karina Clemmensen and Professor Björn Lindahl (Swedish University of Agricultural Sciences, Uppsala) and Dr Mark Garnett (University of Glasgow and National Environmental Isotope Facility (NEIF), East Kilbride).
In the project, the PDRF will apply ground-breaking techniques in the use – and innovative experimental deployment – of natural abundance (and depleted) radiocarbon (14C), together with metagenomics, soil and root-tip enzyme assays and soil organic matter (SOM) analyses, to quantify and understand the processes and dynamics of the mycorrhizosphere and how these affect soil organic C stocks. The research will focus on the process of ‘priming’ (which occurs when material added to soil affects the rate of decomposition of SOM, either positively or negatively), and the specific role of mycorrhizal fungi in this, and related, processes.
The MYCONET team will measure these processes both in situ (in the Arctic and the UK uplands) and in controlled experiments (using specific combinations of tree, shrub and mycorrhizal symbionts), as part of an integrated package of mechanistic studies, soil profile analysis and dynamic SOM modelling, to quantify and understand how priming works, and the implications for SOM dynamics, ecosystem C fluxes, and nutrient cycling.
Potential applications and benefits – By applying ground-breaking techniques MYCONET has potential to transform our understanding of plant-soil interactions and the role of mycorrhizal fungi in SOM dynamics. The fundamental new knowledge gained could significantly improve regional and global modelling of climate-biogeochemical interactions, with a particular focus on the indirect effects of shifting plant communities. The project has relevance for the pan-Arctic ‘shrubification’, as well as for ecosystems being managed for C-sequestration or ‘re-wilding’ in the Scottish Uplands.
Tackling the project’s aims will be through close collaboration with the broader UK and international MYCONET team. The PDRF will be central to the project team and will work with the Principal and Co-Investigators, and Project Partners, to produce the scientific (datasets, research papers and reports, and conference/workshop presentations) and the societal impact deliverables.
Description of Duties
The post holder will be based in Stirling but spend a significant proportion of their time at the University of Edinburgh, in particular, and at the JHI in Aberdeen. Furthermore, in addition to undertaking fieldwork in the Scottish Highlands and in Swedish Lapland, the PDRF will visit the Project Partners in Uppsala, Sweden, to complement experience gained with the team at JHI on fungal community analysis. Natural abundance Radiocarbon determinations will be led by Project Partner Mark Garnett at NEIF (East Kilbride), but the PDRF will also receive expert on-site training there on sample preparation and analysis.
The PDRF will be joining an enthusiastic and welcoming team, with a broad spectrum of complementary expertise, incorporating researchers at a range of career stages and with excellent international contact networks. Team members are well qualified to provide support and mentorship, and the career development of the PDRF will be a key priority of MYCONET.
The PDRF will have full access to the University of Stirling’s training and career development programme under its Institute for Advanced Studies, as well as access to cross-institutional development opportunities afforded by Stirling’s leadership of the recently launched British Academy Early Career Researcher Network Scotland Hub. The PDRF will be encouraged to contribute to internal teaching programmes and technical workshops and conferences, where appropriate.
Please contact Prof Philip Wookey (firstname.lastname@example.org) with any enquiries.
