Table 2 Variance partitioning among and within sampling locations (AMOVA) of three springtail species (Ceratophysella denticulata, Folsomia quadrioculata and Isotomiella minor) sampled across Europe based on sequence variance of the mitochondrial COI gene, the nuclear H3 gene and a concatenated dataset of three genes (COI, H3 and 28S)

From: Founder events and pre-glacial divergences shape the genetic structure of European Collembola species
