Temporal and diet-regulated dynamics of ecological bacterial modules.

<p><b>A</b>. Bacteroides module. Each stacked bar represents the Z score normalized abundance of the component genera indicated in the legend. The diet and time points are indicated on the x-axis and can generally be followed in a temporal manner from left to right. Diets shown are human (undefined starting material), LF/PP (low fat/plant polysaccharide rich chow), WESTERN (Harlan-Teklad TD96132), FASTING (no food). I; initial fecal donor sample, N/A; initial sample prior to inoculation, pg; day following gavage into mouse, pw; day following shift to Western diet, pb: day following return to LF/PP diet, 1pf: day 1 fasting, pf: day after fasting. <b>B</b>. Temporal and diet-regulated dynamics of the <i>Pseudoflavonifractor</i> module. Each stacked bar represents the Z score normalized abundance of the component genera indicated in the legend. X-axis as for A. <b>C</b>. The abundance of the <i>Bacteroides</i> and <i>Pseuodoflavonifractor</i> modules associate with Western-diet. The average Z score for each fecal sample was calculated for both the <i>Bacteroides</i> and <i>Pseudoflavonifractor</i>-module component genera and arranged in order of abundance from left to right. Each bar is coloured by the sample diet.
