RTG 2300: Enrichment of European beech forests with conifers


The research training group (RTG) 2300 “Enrichment of European beech forests with conifers: impacts of functional traits on ecosystem functioning” based at the Georg-August University of Göttingen is funded by the German Research Foundation (DFG) from October 2017 to March 2022. It is investigating mixed forest stands composed of native European beech (Fagus sylvatica), the predominant broadleaf tree species in Central Europe, and highly productive conifer tree species growing outside of their native range (native Norway spruce, Picea abies, and non-native Douglas fir, Pseudotsuga menziesii). It is hypothesized that the mixtures show higher functional diversity than pure European beech stands and that the effects of admixed conifers on ecosystem functioning are more pronounced in mixtures with Douglas fir. To test this hypothesis PhD students and a postdoc from the Faculty of Forest Sciences and Forest Ecology, the Faculty of Biology and Psychology, the Faculty of Economic Sciences of the University and the Northwest German Forest Research Institute (NW-FVA) in Göttingen work in 11 closely linked interdisciplinary subprojects exploring various functional traits of the three species and associated organisms on 40 forest stands differing in tree species composition and site quality.

For further information on the research program see “about”.

The PhD students undergo a concept of qualification based on an ambitious and clearly structured programme of intensive interdisciplinary research and supervision. It exposes the students to a broad array of methods, ranging from molecular genetics, over ecophysiology and isotope analyses to sophisticated regression modelling. The systematic and profound research-oriented qualification will generate highly skilled natural resource managers with topical knowledge and skills that cross disciplinary boundaries and provide key qualifications for careers in academia, the public sector and enterprises.


Offers for student assistants and M.Sc. theses

We regularly offer positions for student helpers and master theses in the context of the RTG. Currently, subproject 3 "Matter cycling and nutrient efficiency in mixed and pure stands" and subproject 4 "Molecular physiology of tree nutrition in mixed and pure beech-conifer forests: interaction with mycorrhizae" are looking for a student to conduct an experiment on N
itrate leaching under Douglas fir: soil biological mechanisms.


Guest Lecture Series 2022

Our guest lecture series is organized in cooperation with RTG 2123 "Conservation of Forest Biodiversity in Multiple-Use Landscapes of Central Europe" in Freiburg and will take place in a hybrid format - in presence talks in F01 streemed via zoom.
If you are interested to join remotely, please register by sending an email to grk2300@uni-goettingen.de with your name and affiliation or reason why you are interested in the talk.
