^aAn expanded version of this table detailing individual studies is available at http://crab2.berkeley.edu/∼pacelab/176.htm. 

^bIncidence of division-level representatives in studies of particular habitat types ranked from most represented to least represented divisions: >75% (•), 25 to 75% (○) or <25% (√) of studies have representatives of division. No symbol indicates division not detected. 

^cExcluding organelles. 

^dProteobacteria are presented at the subdivision level due to the extensive sequence representation of this division. 

^eCannot establish as a monophyletic gorup in all analyses.
