Study ID | ST000102 |
Study Title | Cold adaptation shapes the robustness of metabolic networks in Drosophila melanogaster |
Study Type | Time course during cold exposure for four genetic lines of flies |
Study Summary | Metabolites of cold hardy versus cold susceptible flies were compared using N less than R-based metabolomics. We used 8 replicates per line (2 hardy lines, two susceptible lines), and sampled each line at three time points (before, during and after cold), giving rise to 96 samples total. |
