Dr. Thorsten Balke
I am a physical geographer (Dipl.-Geogr., Leibniz University Hannover, Germany) and coastal scientist (PhD, Radboud University Nijmegen, The Netherlands) with a focus on mangrove and salt marsh ecosystems. My PhD research included experiments with mesocosms and hydrodynamic flumes at the National University of Singapore and the Royal Netherlands Institute for Sea Research, fieldwork in Thailand, Singapore and New Zealand, GIS and modelling studies.
I have broad interest in the interaction between ecology and geomorphology (biogeomorphology) to understand landscape evolution and biodiversity and to better protect and manage dynamic biogeomorphic ecosystems such as salt marshes, mangroves, dunes or river floodplains. I am currently working as a Postdoc within the BEFmate project.
Biogeomorphic landscapes, some examples:
Mangrove pioneer vegetation at low tide, Thailand.
|BEFmate: Biodiversity effects on ecosystem functioning across marine and terrestrial ecosystems|
I am currently working on a large scale experiment in the Waddensea within the BEFmate project. Apart from coordinating the joint fieldwork and the reporting during the construction and monitoring phase, I am interested in the colonization patterns of salt marsh pioneers on the islands vs. the plots within the saltmarsh. I will also monitor the sedimentation/erosion and our working group is responsible for all vegetation surveys.
12 experimental islands, each with 3 height levels. 6 islands are filled with sediment and hence open for new colonization, 6 are planted with lower saltmarsh vegetation at all 3 levels.
At the same heights, we installed plots with the same treatments within the saltmarsh for comparison.
