Amplified fragment length polymorphism (AFLP) suggests old and recent immigration into the Alps by the arctic‐alpine annual Comastoma tenellum (Gentianaceae)
Abstract Aim This study aims to elucidate the phylogeography of the arctic‐alpine annual Comastoma tenellum (Rottb.) Toyok. (Gentianaceae) and to unravel the history of its immigration into the Alps. Location Although samples from Alaska and Central Asia were also included, our study focusses on Eur...
