Fig. 2From: Founder events and pre-glacial divergences shape the genetic structure of European Collembola speciesRelationships of lineages of Folsomia quadrioculata in Europe derived from (a) Bayesian analysis of sequence data of three genes; distinct genetic lineages are indicated by solid (COI) and dashed (H3) lines. b Sampling locations and geographic distribution of COI lineages; white sampling locations are not represented by this speciesBack to article page
