a-f Raw and detrended stem diameter variations (dSDV) in living (grey lines; n=4) and dead (black lines; n=3) saplings and relative air humidity (RH; light grey lines) during 2016 (a, b), 2017 (c, d) and 2018 (e, f). Mean standard deviations (bars) among dendrometer records of living and dead trees (grey and black circle, respectively) are plotted on doy 360 (years 2016 and 2017) and doy 274 (year 2018). Arrows in (a) and (b) indicate timing of tree death deduced from 100 % needle browning. Long-term trends shown for daily SDVs and RH were calculated by fast Fourier transform low-pass filter (28 points). Pearson correlation coefficients (r) among dSDVs of living and dead trees are indicated (*** = P<0.001).
