Job description

The Thünen Institute of Climate-Smart Agriculture offers a PhD position in the research project „Impact assessment of vascular plant encroachment on water and carbon cycling in a Sphagnum dominated bog – VESBO“. The project is supported by the German Research Foundation (DFG). Rewetting of previously used raised bogs is an effective, cost-efficient and widely used measure for greenhouse gas emission reduction and biodiversity conservation. The success of this measure is increasingly threatened by the encroachment of multi-layered tree and grass communities. The causes and effects of this encroachment on the water and carbon cycle are largely unknown.

Project aims:
- the mechanistic analysis of evapotranspiration and carbon exchange of a re-wetted, Atlantic-temperate raised bog under vascular plant encroachment in direct comparison to a site with near-natural vegetation
- the partitioning of ecosystem fluxes and annual balances into moss, grass, tree and soil contributions depending on dynamic environmental conditions
- the characterization of the contribution of the plant functional group to mass and energy fluxes of the bog ecosystem with regard to restoration and emission mitigation measures under changing climatic conditions

The position is based in a working group at Thünen Institute of Climate-Smart Agriculture conducting research on national and international level in the area of organic soils. The project is being carried out in cooperation with the Department of Ecosystem Physiology of the University of Freiburg and the Natural Resources Institute Finland (LUKE). The place of work is Braunschweig. We offer a comprehensive job dealing with a current
research topic that includes process-based soil-plant-atmosphere exchange modeling (SVAT), challenging data analysis, and field and laboratory work.

Detailed tasks:
- Adaptation of the used SVAT model to the conditions of the test sites with special consideration of the multi-layered vegetation cover including bryophytes as well as the soil physical properties of the peat
- Modeling water and carbon fluxes of the two study sites using eddy covariance and chamber flux data to derive ecophysiological parameters of the involved plant functional groups
- Partitioning of the atmosphere exchange at the ecosystem level in peat, moss and vascular plant contributions as well as quantification of the annual balance with propagation of parameter uncertainties
- Assessment of vascular plant encroachment on rewetted raised bog ecosystems with respect to emission reduction and nature conservation targets, as well as the evaluation of common conservation measures
- Contribution to field and laboratory work
- Writing scientific publications
