Geological events impacting the distribution of Malagasy baobabs. Changing sea levels over time (top, GMSL, RSL) 39 , 48 was inferred by different models ( Methods ). The dynamics of the land area of Madagascar (middle) were derived from a calculation using the GMSL (orange patch) and RSL (dash line). The timescale of reported geological events 31 , 48 , 49 is indicated by coloured strips. The predicted suitable areas of habitat for baobabs were mapped onto the simulated territories of the island under different sea-level scenarios (bottom). The acronyms used for species are as in Fig. 1a .
