The Chair of Applied Vegetation Ecology offers a PhD position to carry out research in the research project “Effects of admixing drought-tolerant tree species to beech stands for plant diversity (vascular plants, bryophytes, lichens) (BioDiv)”.
Large forested areas in Germany are presently only dominated by a single tree species, namely mostly either Norway spruce, Scots pine or European beech. Since especially spruce and Scots pine, but even beech, have difficulties to cope with increasing summer drought as the result of climate change, the establishment of mixed forests is discussed as a silvicultural adaptation measure to prevent forest stands from complete dieback in drought years. However, systematic quantitative analyses of the effects of different mixing ratios on biodiversity are lacking so far. Starting from monospecific beech stands, the present project aims at analyzing the effect of admixing additional tree species to beech on plant diversity (vascular plants, bryophytes, lichens). Five different mixing ratios of tree species as well as five different admixed tree species or mixtures of tree species, which are associated with beech, will be investigated.
Expected profile of the candidate:
The PhD position is offered for candidates with a Master’s degree in the fields of biology, forest sciences, environmental sciences or related subjects.
Candidates need to have deepened knowledge of vascular plant identification and need to be able to record the ground vegetation of forests in southwestern Germany. Knowledge of analyzing vegetation data is required. Furthermore, the candidate will have to identify soil types and to conduct physical and chemical soil analyses of the study sites. The candidate must have a willingness and interest to conduct extensive field work and needs a valid driving license.
Applications must include a motivation letter, CV, and copies of certificates.
