“…Divergence times of the bobak group including M. baibacina and the camtschatica group including M. sibirica were estimated to be 3.5-4 Ma (Steppan et al, 2011), i.e., the event occurred relatively soon after an initial invasion of marmots into Asia (4.6 Ma). Allopatric speciation in these groups developed during the epi-platformal orogenesis of Eurasia (Nikol'skii and Rumiantsev, 2012) under the influence of glacial and interglacial events of Middle and Late Pliocene and Pleistocene (Erbaeva, 2003;Polly et al, 2015). Taking the above dates into account, we can say that the duration of M. baibacina and M. sibirica speciation corresponds to the average time of evolution of hybrid inviability in mammals (2-4 million years) (Fitzpatrick, 2004), which is consistent with relatively high genetic interspecific differences between them (Steppan et al, 2011).…”

The role of hybridization as one of the factors of speciation in mammals has been underestimated for a long time, but now there is a lot of data on its impact in mammalian evolution. Hybridization of species often occurs in their secondary contact zones, which is a natural model for testing factors that ensure species integrity. Studies of hybrid zones are increasingly revealing the essential role of ecological and behavioral features both in initiating crossbreeding and in maintaining interspecific barriers. We studied the hybridization of two species of marmots Marmota baibacina and M. sibirica in the zone of sympatry in Mongolian Altai Mountains. We used a bioacoustic approach to determine the localization of individuals of different species and their cohabitation sites. Genetic typing with two diploid nuclear markers and one marker each of paternal and maternal lines was used to identify hybrids. Habitat preferences of marmots were studied to understand the conditions for the formation of heterospecific pairs. We found a high proportion of hybrid individuals in boulder screes where conditions for the formation of heterospecific pairs probably exist. Our data indicate the viability and fertility of F1 hybrids and their descendants. We hypothesize that the environmental preferences and behavioral features of both species of marmots are important factors that both create conditions for hybridization and limit hybrid dispersal.

В работе описаны фрагменты скелетов двух особей, а также отдельные материалы по ископаемому сурку с территории Минусинской котловины. Изучение остатков позволило уверенно отнести их к одному виду Marmota baibacina. Представители рода Marmota непрерывно населяли регион как минимум со второй половины позднего неоплейстоцена до позднего голоцена, но к современности полностью исчезли. Точное время и причины вымирания сурков в регионе пока неизвестны и требуют дальнейшего изучения.Ключевые слова: ископаемый сурок; Marmota baibacina; поздний плейстоцен; голоцен; Енисей, Минусинская котловина; Республика Хакасия.

Genetic evidence for subspecies differentiation of the Himalayan marmot, Marmota himalayana, in the Qinghai-Tibet Plateau

et al. 2017

The primary host of plague in the Qinghai-Tibet Plateau (QTP), China, is Marmota himalayana, which plays an essential role in the maintenance, transmission, and prevalence of plague. To achieve a more clear insight into the differentiation of M. himalayana, complete cytochrome b (cyt b) gene and 11 microsatellite loci were analyzed for a total of 423 individuals from 43 localities in the northeast of the QTP. Phylogenetic analyses with maximum likelihood and Bayesian inference methods showed that all derived haplotypes diverged into two primary well-supported monophyletic lineages, I and II, which corresponded to the referential sequences of two recognized subspecies, M. h. himalayana and M. h. robusta, respectively. The divergence between the two lineages was estimated to be at about 1.03 million years ago, nearly synchronously with the divergence between M. baibacina and M. kastschenkoi and much earlier than that between M. vancouverensis and M. caligata. Genetic structure analyses based on the microsatellite dataset detected significant admixture between the two lineages in the mixed region, which verified the intraspecies level of the differentiation between the two lineages. Our results for the first time demonstrated the coexistence of M. h. himalayana and M. h. robusta, and also, determined the distribution range of the two subspecies in the northeast of QTP. We provided fundamental information for more effective plague control in the QTP.
