Temporary contract | up to 48 months (14 months initial contract) | Belvaux

Are you passionate about research? So are we! Come and join us

The Luxembourg Institute of Science and Technology (LIST) is a Research and Technology Organization (RTO) active in the fields of materials, environment and IT. By generating relevant scientific knowledge and converting knowledge into technologies, smart data and tools, LIST empowers citizens in their choices, public authorities in their decisions and businesses in their strategies.

To address the urgent societal need for science-based management recommendations for forests under increasing pressure, and to leverage on the fast-developing expertise in multi-disciplinary forest research in Luxembourg, LIST, in collaboration with the University of Luxembourg and the Luxembourg Institute of Socio-Economic Research, has formed a dedicated doctoral training unit (DTU) on “Forest function under stress” (FORFUS). It consists of 4 inter-linked research clusters, focusing on below-ground processes, tree and canopy processes, remote sensing observations, and prediction and valuation of forest functions, providing a holistic view on forests as complex systems. See the project website to find out more about the FORFUS doctoral training unit here.

How will you contribute?

Drought changes plant carbon (C) inputs and microbial C cycling; it consistently increases tree root C exudates and alters multiple soil microbial community traits that influence C cycling. Persistent forest soil C contains a large proportion of microbial necromass, especially fungal necromass, and the size and stability of these necromass contributions is determined by tree C inputs, microbial physiology and necromass and tree root spatial interactions with soil minerals. It is unclear how drought-induced changes to tree root C inputs and root architecture will influence the microbial mechanisms that control long-term soil C persistence.

The objectives of this project are to (a) characterize how drought influences tree roots and C release, and forest soil microbial diversity, microbial biomass C turnover, and necromass C persistence; and (b) investigate how drought influences the life strategies and traits of fungi that drive interactions with tree roots, reactive soil minerals and fungal necromass persistence.

The doctoral candidate will leverage on LIST's extensive network of monitoring sites and a new rain exclusion experiment. This project will use passive rain shelters to impose soil drought. Microbial diversity, physiology and traits may be assessed during drought and rewetting cycles (in the field and in the laboratory), using metabarcoding, metagenomics and DNA-stable isotope probing. Microbial physiology and necromass carbon persistence may be determined with stable isotope incubations with native fungal necromass. The relative contribution of microbial necromass and root exudates to persistent soil organic matter may be developed using several GC-MS techniques. Root exudates and architecture changes will be investigated in collaboration with Universities of Tartu (Prof Ivika Ostonen) and Luxembourg (Prof Stéphane Bordas). You will follow the rules and curriculum set out by the Doctoral School in Science and Engineering (https://www.uni.lu/research-en/doctoral-education/dsse/) and engage in courses and activities organised by the doctoral training unit FORFUS.
