  1. Compound classes are assigned to match the grouping of each compound as used throughout the discussion of the manuscript
  2. * = p < 0.05, ** = p < 0.01, *** = p < 0.001. and indicate either an increase or a decrease of the respective compound with rising temperature or rising CO2. ↑↓ indicates apparent uneven effects. Interactive effects are per definition uneven and were therefore not characterized. A plot for each component is available in the (Additional file 4: Figure S1 and Additional file 5: Figure S2 (NMR) and Additional file 6: Figure S3 (HPLC))
