Presentation Transcript

  1. Networks of microbial communities in mud volcanoes Konstantinos Ar. Kormas*, Maria G. Pachiadaki University of Thessaly, Greece HERMIONE Ghent workshop, Nov. 2011 * E-mail: kkormas@uth.gr

  2. Study sites – mud volcanoes from • East Mediterranean • Gulf of Cadiz • Norwegian Sea • Possible to include other sites, symbiotic communities inclued

  3. Data • Bacterial and archaeal OTUs • From published papers but we will also look for unpublished OTUs (GenBank), ask HERMIONE partners if they want to add any of their unpublished data • Effort to identify the lowest possible taxon (family would be satisfactory!) • Distinct depth layers, where available

  4. Network analysis (e.g. PAJEK) • Matrix will include all sites (X) and list of OTUs (Y) • Nodes = sites/depth, links = number of common OTUs • Possibility of weighted network (e.g. methane flow, sulfate)

  5. Visualisation Data matrix Dagan (2011)
