Qualification thesis
Qualification thesis
We supervise a wide range of qualification theses at our AG, covering bachelor and master theses as well as the polyvalent bachelor and master for the teaching profession. In all areas it is important to us to provide good and as direct supervision as possible, which is why we like to link our topics to active research projects or to one of the research platforms we supervise. This thematic linkage to the work of scientists in the research group provides students with a profound insight into research and scientific work. Our portfolio of topics includes work in the field, greenhouse and laboratory as well as topics that deal primarily with data analysis on the computer.Currently, the following focal points are in the foreground with us:
- Diversity in the canopy of the Leipzig floodplain forest - research at the floodplain forest crane in the Burgaue in Leipzig.
- Functional diversity and its effect on the performance of 100 tree species in the research arboretum Großpössna.
- Function of floodplain vegetation - the influence of vegetation on nutrient retention during flooding at the Mulde River.
- Functional characteristics of roots and their importance for ecosystem functions
- Biodiversity in space - can we translate local patterns and mechanisms to larger spatial scales?
We are open to possible adaptations to specific student interests. If you are interested, please contact us directly so that we can present the current topics directly (Prof. Christian Wirth or Prof. Alexandra Weigelt).
