Abstract
The current genetic structure of reindeer and caribou (Rangifer tarandus) is highly influenced by the last glacial period, by different refugial isolation, colonization routes and subsequent range expansions and contractions. Here, the genetic structure and clustering of wild and domestic reindeer in western Eurasia is inferred by merging and analyzing three mitochondrial Tuesday 18 August: Session 7A: Population genetics and evolution Location: Christianus sextus Chaired by Steeve Côté 16:00-16:25 7A.1.

A Bayesian phylogeny and a MJ network, show a high degree of genetic structuring, in particular
within wild reindeer. Two main haplotype clusters and several distinct sub clusters, showing geographical structure, were identified. In addition to previously described haplotype clusters, we found high support for Svalbard reindeer (R. t. platyrhynchus) to constitute a separate group. We also identified control region haplotypes, previously found only on Svalbard, among contemporary reindeer herds and in ancient reindeer material from other Eurasian Arctic islands. This implies that reindeer from these northern Islands have been isolated for a long period of time. We could not find evidence of
haplotype shearing between north American Pearyi caribou (R. t. pearyi) and Svalbard reindeer, indicating an eastern colonization route for Svalbard reindeer from the Beringian refugium to the Svalbard archipelag
