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 representatives of the Red Sea, the PAG, and entire Arabian Peninsula (three right panels). 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 Miller et al. (2005), represented by gray circles. Glacial periods of low sea connectivity are represented in blue and interglacial periods in gold. Full parameter estimates and 95% CI are provided in Table S8 (Supplementary Information).
