Genetic features and the putative sources of formation of isolated populations of the striped field mouse Apodemus agrarius Pallas, 1771 in Magadan oblast

Phylogeography of the striped field mouse, Apodemus agrarius (Rodentia: Muridae), throughout its distribution range in the Palaearctic region

“…However, as this last estimate was calculated for another rodent genus (Mus musculus) from very recent events (200 years), it has to be used with caution. Assuming a generation time (G) for A. agrarius of 0.5 year (Pereverzeva et al 2017), the population divergence time (T) can be converted to calendar years (t in years) and estimates of population mutation rates (θ 1 , θ 2 , and θ A ) can be converted to estimates of effective population size parameters (N 1 , N 2 , N A , respectively, in number of individuals). The migration parameters in the model can be used to obtain population migration rates (i.e.…”

“…The Korean Peninsula, characterised by a temperate mountain climate in its southern part, was less deeply affected by the global Quaternary climate changes (Kim and Park, 2015) and therefore could have acted as glacial refugia for many organisms during the Quaternary coldest phases. The Russian Far East as well as China could also have been a potential Quaternary refugium for A. agrarius (Atopkin et al 2007;Pereverzeva et al 2017;Sakka et al 2010). Corbet (1978) classified A. agrarius populations from Europe and Western and Central Asia as the subspecies A. a. agrarius, while populations from Eastern Asia were considered as the subspecies A. a. ningpoensis.…”

“…Most phylogeographic studies of A. agrarius have focused on a small part of its distribution range (Andersen et al 2017;Gortat et al 2013;Koh et al 2014;Pereverzeva et al 2017;Sheremetyeva et al 2017), but phylogeographic information from datasets including samples from the two main population fragments and based on karyotype variations (Kartavtseva and Pavlenko, 2000) or random amplified polymorphic DNA (RAPD) markers (Atopkin et al 2007) has shown very weak genetic differences among animals from the two fragments, but the Eastern group nevertheless seems to be more heterogeneous than the Western group. These findings were confirmed by another study based on mitochondrial cytochrome b gene (MTCYB) sequences (Sakka et al 2010).…”

Late Pleistocene Expansion of Small Murid Rodents across the Palearctic in Relation to the Past Environmental Changes

“…Currently, we still observe progressive expansion of the striped field mouse (SFM) in Europe [ 14 ], the Siberian region [ 15 ] and far east Russia [ 16 , 17 ], closely related with human activity and habitat transformation leading to increased availability of the SFM’s preferred habitats and potential “new” migration corridors, allowing for overcoming the previously existing migration barriers. In the context of the observed high plasticity of SFM and their ability of fast occupation of newly formed preferred biotopes, this species should be in newly inhabited regions, where it appears as a new, alien element of local fauna, capable to changing the community of small mammals and displacing other “native” species [ 18 , 19 ].…”

Phylogeography of the striped field mouse (Apodemus agrarius Pallas, 1771) in light of new data from central part of Northern Eurasia

“…agrarius has been obtained by analyzing the mitochondrial genome. The phylogenetic relations of continental and island populations of South Korea [ 7 – 9 ], the genetic diversity of populations of the Russian Far East and isolated populations in the Far North (Magadan Region) [ 10 , 11 ], and the history of colonization of the Danish islands by striped field mouse [ 12 ] have all been studied this way. Hypotheses regarding the time, consecutiveness and the possible causes of intraspecific genetic differentiation and the history of the formation of the modern A .…”
