We Need A Field Guide to the Microbes
2004: “Global Field Guide for Microorganisms”
2009 - Call for a Genomic Field Guide to Microbes
Many Challenges
Challenge I: Small, Hard to Study in Field
• Microscope picture
• Microbes are small


• But diversity and numbers
are very high


• Appearance not a good
indicator of type or function


• Field observations of limited
value
Challenge II: Diversity of Form
Challenge III: Diversity of Functions
The Bad The Good The Unusual
The Consumable The Burnable The Planet
Challenge IV: Evolutionary Diversity
Viruses
Bacteria & Archaea Fungi
Other Eukaryotes
Challenge V: Microscale Localization
