Preserved module in female fly metabolome. Architecture of the brown module, a highly preserved module in the female fly metabolome between 18°C (left) and 27°C (right). Nodes represent metabolites and edges represent correlations between the node pairs. Only correlation values of r ≥ 0.7 (red) or r ≤ −0.7 (blue) are shown. The location and relative order of each node in the module are the same across the two temperature conditions.
