“…In the WEST, the mean observed and expected heterozygosities were 0.76 and 0.78, respectively, and the number of alleles per locus was 8.8. This level of genetic diversity in the Korean populations is similar to those in the Chinese populations of the species and a closely related species (Apodemus latronum; Wu and Zhang, 2009). Overall, Korean field mice revealed much higher genetic variation than found in many other vertebrates (DeWoody and Avise, 2000;Eo et al, 2011).…”

To provide more reliable genetic information on species and minimize experimental errors, biologists increase the number of genetic markers available and then carefully select optimal markers from a large candidate pool. We developed nine novel microsatellite markers from the Korean field mouse (Apodemus peninsulae), which is one of the most dominant forest animals in South Korea. The mean observed and expected heterozygosities across nine markers were 0.65 and 0.73, respectively, with an average polymorphic information content of 0.70. Using 17 microsatellite markers (nine polymorphic markers in this study, in combination with eight previously reported for the species), we conducted genetic analysis on the animals from six sampling locations. These locations are divided into the eastern (EAST) and the western (WEST) sides of the Taebaek mountain ranges in South Korea. Genetic diversity was high at both groups, with the mean expected heterozygosity of 0.77 in EAST and 0.78 in WEST. However, we did not observe strong evidence of genetic divergence between two groups. Future genetic research with more samples incorporating ecological study may clarify population structure in the species and the hypothesis of the mountains discontinuity of gene flow.

“…We screened the A. speciosus DNA samples for 12 microsatellite loci that had been developed for A. agrarius , A. argenteus , A. sylvaticus , and A. peninsulae (Makova et al ., ; Ohnishi et al ., ; Wu & Zhang, ). Six of the twelve loci that were reliably amplified were polymorphic in A. speciosus .…”

To infer the evolutionary mechanism of phenotypic variation among isolated island populations, we investigated coat colour and genetic variation in the large Japanese field mouse (Apodemus speciosus) on the Izu Islands (Ohshima, Niijima, Kouzushima, and Miyakejima). Coat colour in the most remote population (Miyakejima) was unique and significantly darker than that in the other populations. Ohshima that is closest to the source population showed variation in coat colour within its population. Phylogeographical analyses using mitochondrial and microsatellite markers suggested that the island populations (except Kouzushima) were founded sequentially from the closest Ohshima to remote Niijima and Miyakejima during or before the penultimate interglacial period. Secondary gene flow from the source population was rare and occurred only for the closest (Ohshima) population. In addition, we found that an amino acid mutation in the Agouti signalling protein gene (Asip) was associated with coat colour variation among the island populations. The mutation was rare in the source population but completely fixed in the Miyakejima population. The phenotypic and genetic variation suggested that severe reduction of genetic variation and changes in allele frequency as a result of sequential colonization (i.e. the founder effect) had significant effects on colour polymorphism. The findings of the present study suggest that the founder effect, in addition to natural selection, facilitated the morphological changes below the species level over a relatively long time scale.
