Figure 5

PCA component analysis (PCA) on phenotypic measurements of the 7 colonies at the end of the experiment, after being exposed to MMM +4 °C for 10 days. Component loads projected on the first two components are depicted in arrow. Numbers in parentheses represent the proportion of variance explained by that principal component. The barplot on the right-hand indicates the contribution of each phenotypic measurements to the first principal component.
