Freshwaters

  • Drinking water quality
  • Eutrophication impacts
  • Climate and weather impacts
  • Carbon cycling

Defining the freshwater microbiome

  • Who is there?
  • What are they doing?
  • Who is doing what?
  • How does this change over time/space
slide-6
SLIDE 6

Who is there?

  • Viruses
  • Bacteria
  • Protozoa
  • Fungi
  • Phytoplankton
  • Zooplankton
  • Other eukaryotes (e.g. Oomycetes)

Microbe-Activity Linkage (Long-Term)

  • What does the future hold?
  • Will freshwater systems continue as sources of GHG emissions?
  • Will eutrophication/warming
  • Can we begin to predict how lakes will evolve or whether they will

stay the same?

  • Can/Should we intervene to “save” lakes?

Take home messages

  • Freshwaters contain discrete and ever changing microbial populations
  • Applications of modern sequences approaches should be considered

carefully with respect to new and traditional microbiological and biogeochemical methods

  • Microbiome research in freshwater systems allows us to generate

hypotheses applicable also to marine and terrestrial systems

  • Freshwater microbiomes are critical components of the whole earth

system
