Beschreibung: The Chair of Ecosystemphysiology invites application for a
PhD position
Part-time position (65 %), Start-date: At the earliest possible date.

with 65 % of the regular weekly working time, limited to three years, in the research project „Impact assessment of vascular plant encroachment on water and carbon cycling in a Sphagnum dominated bog - VESBO“. 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.
Methoden: - 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.
