The Impact of the Geologic History and Paleoclimate on the Diversification of East African Cichlids

Bathymetric maps of Lakes Tanganyika, Malawi, and Victoria for modern, Last Glacial Maximum (15–32 ka), megadrought period (~100 ka), and the middle Pleistocene (~1 Ma). Reconstruction for ~1 Ma is based on data from Lake Tanganyika’s subbasin [13], which has been extrapolated to the rest of the lake. Thus, this reconstruction is speculative and must be verified by additional data from the central and southern subbasins of Lake Tanganyika. Shaded areas show the maximum extent of lake during each interval. Lake Victoria’s islands are shown in black. Lake levels based on [10, 13–22]. Bathymetric maps based on data from the World Lake Database (http://wldb.ilec.or.jp/).
