Tests of Pleistocene speciation among alpine and montane species of Globularia (Globulariaceae) from the European high mountains

Abstract

There has heen a resurgence of dehate among zoologists on whether the Pleistocene glaciations inhibited speciation. Here we test the hypothesis of Pleistocene speciation by focusing on tbe phylogenetic relationships and divergence times of various alpine and montane plant species of the genus Globularia L. from the European high mountains.
