Aim The post-glacial range dynamics of many European plant species have been widely investigated, but information rapidly diminishes as one moves further back in time. Here we infer the historical range shifts of Laurus, a paradigmatic tree of the Tethyan flora that has covered southern Eurasia since the Oligo-Miocene, by means of phylogenetic and phylogeographical analyses. Location Mediterranean Basin, Black Sea and Macaronesian archipelagos (Azores, Madeira, Canary Islands). Methods We analysed plastid DNA (cpDNA) sequence (trnK-matK, trnD-trnT) variation in 57 populations of Laurus and three Lauraceae genera. Phylogenetic methods (maximum parsimony and Bayesian inference) and statistical parsimony networks were used to reconstruct relationships among haplotypes. These results were contrasted with the fossil record and bioclimatic niche-based model predictions of past distributions to infer the migration routes and location of refugia. Results The phylogenetic tree revealed monophyly for Laurus. Overall sequence variability was low within Laurus, but six different haplotypes were distinguished and a single network retrieved, portraying three lineages primarily related to geography. A strongly divergent eastern lineage occupied Turkey and the Near East, a second clade was located in the Aegean region and, lastly, a western clade grouped all Macaronesian and central and western Mediterranean populations. A close relationship was observed between the Macaronesian populations of L. azorica and the western populations of L. nobilis. Main conclusions The phylogeographical structure of Laurus preserves the imprints of an ancient contraction and break-up of the range that resulted in the evolution of separate cpDNA lineages in its western- and easternmost extremes. Intense range dynamics in the western Mediterranean and multiple glacial refugia contributed to the generation and long-term conservation of this phylogeographical pattern, as shown by the fit between the haplotype ranges and past suitable areas inferred from bioclimatic models. Finally, our results challenge the taxonomic separation of Laurus into two distinct species. © 2009 Blackwell Publishing Ltd.
