Phylogenetic analyses of Eurasian lynx (Lynx lynx Linnaeus, 1758) including new mitochondrial DNA sequences from Iran.

The Eurasian lynx (Lynx lynx) is one of the widespread felids in Eurasia; however, relatively little is known about the Asian subspecies, and especially the Iranian populations, which comprise the most southwestern part of its range. The current study aimed to assess the phylogenetic status of Iranian populations relative to other populations of Eurasia, by sequencing a 613 bp fragment of the mitochondrial control region. In total, 44 haplotypes were recorded from 83 sequences throughout Eurasia, two of which were found in Iran. The haplotype (H1) is dominant in all Iranian lynx populations and identical to specimens from SW Russia and central China. The second haplotype (H2) is unique and was recorded only from Ghazvin Province in the central Alborz Mountains. Both haplotypes occur in Ghazvin Province. The phylogenetic tree and a median-joining network identified four clades (i.e., East, West 1, West 2, and South). These results are congruent with previous studies and suggest that Eurasian lynx was restricted to the southern part of its range during the glacial maxima and expanded from there to East Asia and to Europe during several independent re-colonization events. The Caucasus region most like plays an important role as a refugium during glacial cycles.
