The existence of global distribution patterns in the case of most plants and animals is a well-known fact. However, for microorganisms for long time, the prevailing idea has been that biogeographic patterns do not exist and instead according to the Baas-Becking hypothesis “Everything is everywhere, but the environment selects".

What is the basis of this hypothesis and to what extent are microorganisms really unconstrained in their distribution patterns? What are the main dispersal processes in the case of microorganisms and how do they differ from those of "macroorganisms"? How does the environment select? What are the particularities of aquatic microbial dispersal and how do they affect microbial communities and aquatic ecosystems?

This lecture will aim to answer these questions through both well-established microbial ecology concepts and state-of-the-art results of the field.


The lecture is an examination to be admitted as a docent and should be at the knowledge level of undergraduate students but could also be of interest to a wider audience. The lecture is 45 minutes and is followed by time for questions and discussion. The lecture will be given in English.


Chair: Professor Peter Eklöv
