Fig. 4 Changes in distribution range from the LGM (minority prediction)
to present day (a, d, g, j), predicted elevational range during the LGM
and at the present day (b, e, h, k) and historic effective population
size (c, f, i, l) of H. tibetana (a, b, c), H. digitata(d, e, f), H. gregoryi (g, h, i), H. platon (j, k, l). The
white dots in the distribution range size map show the actual
observation of each population. In the predicted elevational range plots
(b,e,h,k), the grey line presents the background elevation range of the
whole study area, and the dashed line indicates the mean elevation of
the suitable area of species at a time scenario (purple: during the LGM;
cyan: at present). The maps can be viewed online at the original spatial
resolution at https://fred.igb-berlin.de/data/package/812. The
y-axis of the PSMC plots for H. gregoryi (i) was re-scaled to
filter the noise closer to the present time (~5,000
years before the present).
