Table 2.

V. fischeri EM17 and EM17Tn7 evolved in FLM pH 6.0, 10.0, and 6.0/10.0 were competed against their opposingly marked ancestor (n=20). Independent two-sample t-tests were conducted between these competitions (two-tailed, Type 1 α error=0.05)

The same key in Fig. 1 is also used here for ‘EM2000’, ‘TN2000’, etc.
