Mitochondrial cytochrome b sequences resolve the taxonomy of field mice (Apodemus) in the western Balkan refugium
Boris Kryštufek, Martina Lužnik, Elena Bužan, 2012, izvirni znanstveni članek

Opis: Apodemus sylvaticus stankovici, described from the topographically rough landscape of the western Balkan glacial refugium, was recently proposed as being either a junior synonym of Apodemus flavicollis or a species on its own right. To untangle this taxonomic vagueness, we sequenced complete cytochrome b gene in 28 field mice collected at 12 locations in the mountains of Bosnia and Herzegovina, Montenegro, western Macedonia and northern Greece. Samples yielded 27 new haplotypes which clustered into two distinct groups. One of these clades also included the reference haplotype of A. flavicollis, while another cluster emerged as being identical with the reference sample for A. sylvaticus. As is common in Apodemus, both species retrieved in our analysis were characterized by low levels of intraspecific variation (0.4- 0.9%) as opposed to a high level of differentiation between them (8.0-10.0%); therefore, the taxonomic classification of our material was without doubt. We found no evidence regarding the presence of an additional cryptic species in the mountains of the western Balkans. The very similar values of genetic variability in the two species imply their common evolutionary history of a long-term coexistence in the western Balkan refugium

Mitochondrial sequences point on a cryptic species in five-toed jerboas, subgenus Paralactaga
Boris Kryštufek, Atilla Arslan, Adwan Shehab, Mounir Abi Said, Sara Zupan, Martina Lužnik, 2013, izvirni znanstveni članek

Opis: We addressed the species taxonomy of five-toed jerboas ( Allactaga , subgenus Paralactaga ) in the Middle East by applying molecular markers (cytochrome b and a partial 16S rRNA). The study consisted of 17 specimens from eight localities in the Middle East, representing both species: Allactaga euphratica and Allactaga williamsi . The phylogenetic reconstructions yielded three highly divergent lineages, which failed to conform to the recent taxonomy of Paralactaga . The first lineage ( williamsi lineage) encompassed all the samples of A. williamsi from Turkey and Iran and also the specimens of A. euphratica from Lebanon. The haplotypes of A. euphratica were arranged into two lineages, which showed strong geographic associations. One lineage contained samples from Harran in Turkey and from Iran, while all the samples from Syria clustered in another lineage. The pairwise Kimura twoparameter values suggested similar divergences between the three lineages and were within the range reported for a sister species of rodents. Our results point to a cryptic species in A. euphratica and also provide evidence of the expanded range of A. williamsi further south of Lebanon
