New Publication about modelling invader impact in dune ecosystems
A new study about modelling the impact of the invasive, nitrogen (N)-fixing shrub Acacia longifolia on N cycling in a nutrient-poor dune ecosystem was published by André Große-Stoltenberg and Dr. Jan Thiele of the research group Ecological Planning within the projects DeInVader (funded by EUFAR) and QUEEN (DFG) in the journal “Scientific Reports”. The team presents a new approach. Read further... The university paper published a short article Link.

New research project: Investigation of historical land use in the Biodiversity Exploratories
In the current phase of the DFG priority programme 1374 'Exploratories for large-scale and long-term functional biodiversity research' (2017-2020), Dr. Jan Thiele (Research Group Applied Landscape Ecology and Ecological Planning) got a grant for a project on effects of historical land use on species communities in grasslands (HiLUCC) that will be carried out in cooperation with Prof. Dr. Wolfgang Weisser, TU Munich. In this project, previous land use - dating back to ca. 1850 - around study plots (1-km radius) will be digitalised from historical maps. For this objective, we are looking for two student helpers with each 8 working hours per week (if you are interested, please mail to Jan Thiele). We will study if the land-use history of grassland plots as well as the historical landscape structure continue to have an effect on today's species communities. For example, fragments of previously large grassland areas may have an extinction debt. On new grassland parcels, species richness might depend on the presence of larger grassland areas and, thus, large species pools in the past. There will be possibilities to conduct MSc. theses in the frame of this projcet, e.g. on landscape change in the study areas Schorfheide-Chorin and Schwäbische Alb.
The HiLUCC project is situated in the research topic "Detection of landscape changes" of the Research Group Applied Landscape Ecology and Ecological Planning.
Successful Follow-Up Application - Prolongation of the ESCAPE project
Dr. Ute Hamer (Soil Ecology and Land Use), Dr. Till Kleinebecker and Prof. Dr. Norbert Hölzel (both Biodiversity and Ecosystem Research Group) successfully applied for a prolongation of the ESCAPE project within the Biodiversity Exploratories at the DFG (Deutsche Forschungsgemeinschaft - German Research Foundation). In close collaboration with Prof. Dr. Markus Fischer and Dr. Daniel Prati from the University of Bern the effects of seed addition and disturbance on plant diversity, nutrient retention and litter decomposition along a land-use gradient will be further evaluated in the SADE experiment. Coordinated by postdoc Dr. Valentin Klaus this project stage will again facilitates students projects and theses.
