abstract = "As the most widespread rodents in the temperate Palearctic, species from the genus Apodemus can (
provide in1portant clues for understanding how extant flora and fauna \\:ere established. Here we (
explore how to determine six Apodemus species precisely at the individual level, evaluate genetic
variation in local populations, geographic regions and species as a whole, and reconstruct their l
phylogeny. Since the genetic variation of natural populations from different parts of a species'
geographic range could result from persistence in different refuges during the last glacial period and the following re;olonization processes, our fmdings are discussed in that perspective. The Inter Simple Sequence Repeat- Polymerase Chain Reaction produced highly reproducible and polymorphic DNA
markers. Each of six optimized ISSR primers was sufficient for precise determination of six Apodemus I
species and gained 98.3% polymorphic bands on a total sample of 91 individuals from 32 sample
localities from Europe and Asia. Phylogenetic trees were inferred from Nei's original .genetic distances and the parameters of intra- and interpopulation and regional genetic variation were calculated.
'
Distances between species ranged from 0.072, among closely related A. jlavicollis and A. sylvaticus, to
0.185 between A. mystacinus and A. agrarius. The tree topology was mainly in accordance with the existing phylogenetic relationships generally established for this genus, but, the range of interregional genetic distances within A. sylvaticus and A. ura/ensis reached the values obtained for closely related species. According to our results, division of A. mystacinus and A. epimelas into subgenus Karstomys, is not sound, although karyological differences support separation from the Sylvaemus group. Species A. uralensis, A. fl.avico/lis and A. sylvaticus display a strong population substructure. Based on the high divergence between southeastern geographic regions, we can hypothesize that A. sylvaticus survived in additional northern refugia, besides the traditionally accepted one. Moreover, high genetic distances together with, high intrapopulation variability in A. jl.avicollis, indicate that there were probably many long-term isolated glacial shelters. This genetic evidence, together with other paleontological data, make it unlikely that physiographically complex and large Balkan Peninsula, offered a single homogenous refugium throughout the Pleistocene.",
