“…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).…”

To better understand the evolutionary history of oriental wildlife newcomers in Europe, we studied the phylogeography and demographic history of the striped field mouse, Apodemus agrarius, throughout its Palaearctic distribution area. Genetic datasets including cytochrome b gene sequences and microsatellite markers were analysed using a large range of population genetics methodologies, including coalescent models and approximate Bayesian computations. Our results showed high mitochondrial genetic homogeneity among A. agrarius populations throughout the Palaearctic region, but microsatellite markers detected a finer population structure with the genetic differentiation of populations from the Eastern and Western distribution ranges. The Western colonisation likely originated from Far East Russian populations during one of the last interglacials. After their colonisation of the Central Asia and Western regions, the Central Palaearctic populations became isolated from their Eastern relatives. Our coalescent-based approaches suggested a separation between these two distribution ranges around 38 kya or more recently (around 11 kya). Limited gene flow still happened between populations in the two main distribution ranges, mainly from the Eastern to Western populations. Our study, for the first time, provides an overview of the evolutionary and demographic history of the striped field mouse throughout the Palaearctic region. A. agrarius appears to be an Asiatic immigrant and a relatively new member of the European fauna community. This study further confirms the important role of Far East Asian regions as a source of European biodiversity.

“…It is well recognized that mammals from isolated island populations often display morphological divergence from their mainland counterparts (Khidas, Duhaime & Huynh, ; McFadden & Meiri, ; Sheremetyeva et al , ) although this pattern is highly variable. They develop distinct morphological and behavioural variations such as variations in fecundity, rate of sexual maturity, levels of sexual dimorphism and innate aggression and most notably body size, with insular dwarfism or gigantism commonly observed (Lomolino, ; Raia et al , ; Lomolino et al , ).…”

Highly promiscuous paternity in mainland and island populations of the endangered Northern Quoll

Polyandry is a commonly utilized strategy in mammalian reproductive systems, where females engage in mating with multiple males to increase either the genetic diversity or quality of their offspring. Some species also exhibit male semelparity, a peculiar life‐history trait where all or most males within a population begin to die following mating. The northern quoll (Dasyurus hallucatus) possesses both of these reproductive adaptations, and females of this species may produce up to eight young in a single litter. Here we aimed to quantify whether there was any difference in female quolls’ choice of male sires between two genetically distinct populations located in the Pilbara region of Western Australia (one mainland‐dwelling and one island‐dwelling population). The total parentage exclusion probability was 0.9999 for excluding a candidate parent from parentage, given the genotype of a known mother. Overall, we found that every litter had young resulting from multiple males. In some litters, a different male fathered every offspring. Thus, northern quolls demonstrated a greater level of polyandry than has previously been detected in marsupials. Furthermore, females from the less genetically diverse island population exercised mate choice and preferentially bred with males that were, on average, 20% smaller than a different male randomly sampled from the island. There was no detectable difference with regard to male sire body size in the mainland population, indicating a difference of selective pressures for the two populations.
