Resumen: 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 re...
