Moore Notes 9 12 15

Group Call

• Participants: Katie, Tom, Patrick, Ladan, Guillaume, Josh, Stephen, Dongying

• Call time: every other week is good
  • Want to refocus for the last year of the grant
  • Longer meeting (in person or not) to set priorities and identify synergies

• Tara Oceans
  • Stephen ran metagenomes (bacterial size fractions) through PhyloCNV pipeline
    • Species abundance
    • Gene copy number variants (CNVs) for abundant species
    • Single nucleotide variants (SNVs) for abundance species
  • Stephen also ran ShotMAP for protein family RPKGs for KEGG
  • Josh looked legacy effects (past climate predicting current microbial distributions better than current climate)
    • Niche modeling code
    • Taxa do not have much evidence of legacy effects, but protein families (KOs) do
      • Bimodel distribution of KO best models - some 1960, some current
      • Need to check for technical issues
      • Surprising perhaps for marine bacteria and given taxonomic results
    • Could predict future distributions if climate equilibrated
    • Katie: think about model assumptions, check residuals
    • Patrick: check colinearity of environmental variables, also if past climate is driving current variables (nutrients?)
  • Who else can use this data?
    • Tom: Inferring function of protein family from ecological conditions where it is found
      • Katie: Could we use CNVs and thereby control for taxonomy (at species level)?
