TRANSCRIPT
Microbial Ecology the power of the small
Research Themes & Topics
I. Diversity & dynamics - effects of climate change, land use - microbiome assembly, succession - motility & dispersal
II. Interactions & communication - microbe-microbe, microbe-protozoa - microbe-eukaryote interactions - signaling, volatiles
III. Activity & natural functions - biogeochemical cycling – GHG - decomposition organic matter - protection eukaryotes against stress - enzymes, antimicrobials & volatiles
IV. Tools & bioinformatics - meta ‘omics & network analyses - genomics & genome mining - chemical detection, imaging - stable isotope probing
Wetlands store most of the terrestrial carbon but….also are the most important source of methane emission into
the atmosphere and thereby regulate our climate.
I. Microbial diversity & dynamics Example 2: methane-oxidizing/methanogenic microorganisms
I. Microbial diversity & dynamics Example 2: soil/rhizosphere/endophytic microorganisms
