“…Most of these events of population displacement were triggered by lake level fluctuations, which extended to a few hundred meters below present level (Lezzar et al, 1996;Cohen et al, 1997;Scholz et al, 2003;McGlue et al, 2008). While the effect is widely seen in population genetic studies on various Lake Tanganyika cichlid species (Verheyen et al, 1996;Rüber et al, 1999Rüber et al, , 2001Duftner et al, 2006;Koblmüller et al, 2007Koblmüller et al, , 2009Koblmüller et al, , 2011Sefc et al, 2007;Nevado et al, 2013;Van Steenberge et al, 2015), studies specifically testing for the impact of Pleistocene water level fluctuations are scarce (Koblmüller et al, 2011;Winkelmann et al, 2016).…”
