Fig. 5: How robust is the gut microbiota of Atlantic cod to taxonomic perturbation?

a Potential robustness to perturbation magnitude (attenuation) increased over time in the hindgut of juvenile Atlantic cod, with highest values in the ASCO_LG dietary treatment. In the boxplots, center value lines indicate the median, boxes indicate the lower/upper quartiles (25%/75%) and lines extending parallel from the boxes (whiskers) show the variability outside the upper and lower quartiles. Lines connecting categories shows significant relationships (pairwise t-test) with *(p < 0.05), **(p < 0.01), or ***(p < 0.001). b Potential buffering capacity towards functional perturbation was relatively stable over time and across treatment groups. In the boxplots, center value lines indicate the median, boxes indicate the lower/upper quartiles (25%/75%) and lines extending parallel from the boxes (whiskers) show the variability outside the upper and lower quartiles. Lines connecting categories shows significant relationships (pairwise t-test) with *(p < 0.05), **(p < 0.01), or ***(p < 0.001). c The microbial communities in the hindgut of juvenile Atlantic cod were separated according to variation in gene distribution features (GDF) between Week 0 and Week 8/12 macroalgal dietary treatments. The points represent grouped samples with ‘Time’ denoted by symbols and dietary treatments denoted by colours; Week 0 (blue), CTRL (red), ULVA (green), ASCO_N (light orange), ASCO_LG (dark orange). The percent variance explained by each principal component is indicated on the axis labels. The line and box with the GDF name show the direction of the GDF vectors.
