Figure 1From: Long-term experimental evolution in Escherichia coli. X. Quantifying the fundamental and realized nicheEffect of 10,000 generations of evolution on total catabolic function. Each point is the weighted average of performance on 68 substrates; 1.0 is the ancestral value. The evolved populations (circles) had significantly lower diet breadth (t = 9.49, df = 11, p < .0001, one-tailed) than the mean of the common ancestors (ANC, triangle). Error bars are standard errors.Back to article page
