Understanding the mechanisms and processes of shaping the Earth’s surface is fundamental to life on Earth and of major interest to geomorphological, geological, soil ecological, microbiological and hydrological sciences. Advances in high-throughput genotyping technology have markedly improved our understanding of the role of microorganisms in chemical transformation of soils and sediments and suggest the enormous potential of microorganisms to shape the Earth surface in close interrelation with climate and tectonic forces. To investigate which microorganisms act as structure engineers and how they control land surface development, we determine microbial community structures and processes in relation to surface processes and climate under natural conditions and environmental simulations in the laboratory. We use an interdisciplinary approach to combine cutting edge technologies from different disciplines and pair with scientists from (bio)geochemistry, soil science and geomorphology in a unique way during all steps of analyses. This approach leads to a better understanding of observations on different time scales and from different professions.
Scientific key questions
- What is the initial assembly of microbial communities in terrestrial ecosystems and what is their function in nutrient, energy and mass fluxes?
- Which microbial functions/traits control soil formation and stabilize the Earth‘s surface?
- How do microbial communities react on changes related to tectonic and climate events?
