DOIAbstract
AimTwo main biogeographical hypotheses have been proposed to explain the Mediterranean‐Turanian disjunct distributions exhibited by numerous steppe‐dwelling organisms, namely (a) dispersal during the Messinian salinity crisis (∼5.96–5.33 Ma) followed by range fragmentation and vicariance, and (b) Pleistocene colonization and recent processes of population subdivision (<2 Ma). Despite the two hypotheses postulate the role of climatic alterations and changes in landmass configuration on determining such disjunct distributions, estimates of the timing of lineage diversification have not been complemented so far with spatially‐explicit tests providing independent evidence on the proximate processes underlying geographical patterns of population...
