Graphs showing the raw stable isotope series for the four trees studied at (a) Danum (S. superba and S. johorensis) and (b) Imbak (E. zwageri). Filled diamonds, S. superba; open diamonds, S. johorensis; filled circles, E. zwageri (Tree T6B2); open circles, E. zwageri (Tree T5B1). Grey error bars represent the uncertainty in age–growth model (1 sigma ≈ ±40 years) expressed as the running standard deviation of tree response over a 40 year period.
