Join the lab!

Interested students are welcome to participate in the research conducted in our lab throughout the year. Open PhD and Postdoc positions will be announced at this page. We offer different topics for bachelor and master theses and also welcome your ideas and suggestions for other thesis topics. Please find a selection of topics listed or request further topics by contacting Prof. Nico Eisenhauer.


Non-scientific personnel

Technical employee (50%), 3.5 years (German and English speakers welcome)

We are looking for a part-time (50%, ~3.5 years) technician for field and lab work for our exciting BetaFor project. If needed, an increase in working hours can be discussed. Please note that the position is advertised in both German and English, and we welcome any interested person who is keen on fieldwork in German forests but also likes to do lab work. Of course, our focus is strongly on the soil system.

If you have any questions, please feel free to contact Simone Cesarz.

In BetaFor, we investigate if we can increase multifunctionality in German production forests by increasing structural complexity at the landscape level – a unique approach considering α-, β-, and γ-diversity in an experimental approach. To increase structural complexity, we use different silvicultural interventions at the patch (50 x 50m) level (Panel A), i.e., different kinds of deadwood and light manipulation, and aggregate those at the landscape level and compare it to a control district (Panel B). This pairing of control and “complexity” districts (ESBC = Enhancing of Structural Beta Diversity) is done in 11 forests in Germany (Panel C).

The single interventions are already running. The technical employee, the respective PhD student, and student helpers, will take soil samples together at all locations and process those samples in the lab to investigate soil multifunctionality.

More details are avilable in the German and English PDF.


PhD positions

Promotionsprojekt „Trockenes Grünland“

Haben Sie einen Master-Abschluss in der Ökologie (oder in einem verwandten biologischen Teilgebiet) und möchten den Einfluss von extremen Dürre-Ereignissen auf Ökosysteme erforschen und zu diesem Thema auch promovieren? Suchen Sie nach einer Möglichkeit, unter sehr guter fachlicher Betreuung einen eigenen Projektantrag für eine solche Promotionsstelle an die Deutsche Bundesstiftung Umwelt (DBU) zu richten?


Wir – Prof. Nico Eisenhauer (iDiv Leipzig: Experimentelle Interaktionsökologie) und Dr. Harald Auge (UFZ Halle: Experimentelle Ökologie von Populationen und Lebensgemeinschaften) – möchten Sie gern dabei unterstützen, einen solchen DBU-Antrag anzufertigen, und möchten Ihre Promotionsarbeit bei einer Bewilligung dieses Antrags auch betreuen.
