Microbial communities are key components of all global biogeochemical cycles and play a central yet poorly understood role in climate change biology. Andreas Richter’s group investigates how growth and turnover of microbial communities control the deconstruction and mineralisation of organic matter in terrestrial ecosystems in current and future climates. The group has redefined and expanded the concept of microbial carbon and nitrogen use efficiency, linking it to ecological stoichiometry theory.

Andreas also pioneered the development of methods to estimate microbial growth and carbon use efficiency based on stable oxygen isotopes. Andreas’ research group has extensively worked on soil organic matter storage in arctic ecosystems and permafrost-climate feedback, as well as in deep soils from the tropics to arctic. They also explore the interactive effects of future climate conditions and climate extremes on microbial processes, community composition, and plant-microbe interactions.

Research Topics

  • Carbon use efficiency, growth and turnover of microbial communities
  • Arctic soil carbon storage and the permafrost-climate feedback
  • Microbial communities, SOM composition and the breakdown of organic matter
  • Ecological stoichiometry and nitrogen and phosphorus cycling
  • Effect of climate change and elevated CO2 on soil processes
