This research cluster focuses on the ecology of marine organisms from the individual organism level to communities and on their interactions with the environment. Our main research areas are:

  • plankton ecology & benthic ecology
  • invasive species & biodiversity
  • symbiosis
  • microbial oceanography & marine biogeochemistry
