Figure 4. Population and demographic history of the Arabian
mangroves. Graphic summary of the demographic models that better fitted
the SFS and corresponding times of divergence computed in fastSIMCOAL2
for the Red Sea (middle panel) and the PAG (right panel). Historical sea
level fluctuations through the glacial cycles of the Quaternary are
provided in a consistent temporal scale (left panel) based on
calibration points reported in (80 ), represented by gray circles.
Glacial periods of low sea connectivity are represented in blue and
interglacial periods in gold. Full parameter estimates and CI % are
provided in Table 2.
