“…The Yellow Sea separating Korea and central China was entirely land during the last glacier, about 20,000-10,000 years ago (Chung 2007). The Chinese water deer, Hydropotes inermis, was formerly widespread in eastern Asia from east China (Guangdong of southern China to Liaoning of northeast China) to the Korean peninsula (Grubb 2005).…”

Two Sympatric Phylogroups of the Chinese Water Deer (Hydropotes inermis) Identified by Mitochondrial DNA Control Region and Cytochrome b Gene Analyses

et al. 2009

Mitochondrial DNA (mtDNA) control region (927 bp) and cytochrome b gene (1,140 bp) sequences of the Chinese water deer (Hydropotes inermis) from China and Korea were obtained to examine the taxonomic status of two subspecies, H. i. inermis from China and H. i. argyropus from Korea. Two sympatric mtDNA clades (a major clade from China and Korea and a minor clade from Korea) with an average genetic distance of 2.1% in the control region and 1.3% in the cytochrome b gene were detected. These findings are not consistent with the current classification by pelage color. We propose a reconsideration of the validity of the subspecies designation by the statistical comparison of morphological characters including body color. The major common mtDNA phylogroup in the two allopatric subspecies could be explained by the contiguous distribution of the Chinese water deer from east China to Korea until recent years. The restriction in the range and number of the Chinese subspecies after the last glacier might have caused the disappearance of the minor phylogroup in China. The taxonomic status of the two groups in Korea should be clarified using nuclear DNA marker analyses as well as morphological characters including pelage color.

“…Although the Holocene has been known as relatively stable period, some climatic fluctuations such as Preboreal and the Holocene climatic optimum were recognized (Bond et al, 1997;Wang et al, 2001;Gupta et al, 2003;Magny, 2004;Hong et al, 2005;Anderson et al, 2007). The vegetation shift from the late-glacial to post-glacial in the southern part of Korea was represented by a sharp decrease in herbs and subalpine conifers, and a remarkable increase in cool temperate deciduous broadleaved trees (Yasuda et al, 1980;Chung, 2007;Chung et al, in press). With the start of the Holocene Artemisia-Gramineae dominated open grassland during the late-glacial was replaced by deciduous broadleaved forests in response to a rapid warming during the Preboreal.…”

To investigate the Holocene vegetation and climate changes, pollen analysis performed on swamp deposits of the Boseong area, South Korea. From ca. 11,800 to 10,500 cal. yr BP, a cool temperate deciduous broadleaved forest dominated by Alnus and Quercus (Lepidobalanus) occupied the study area, indicating climatic warming during the Preboreal (earliest Holocene). A remarkable decrease in riparian Alnus and an increase in xerophytic Artemisia from ca. 10,500 to 8,400 cal. yr BP suggest open woodland with herbaceous understory reflecting a cool and dry condition. The expansion of deciduous broadleaved forest combined with rise in evergreen broadleaved taxa and the retreat of grassland between ca. 8,400 and 3,700 cal. yr BP indicate a vegetation shift from open woodland with herbaceous understory to warm temperate evergreen and deciduous broadleaved forests, resulted from climate amelioration during the Holocene climatic optimum. A warm and humid condition during this period is also evidenced by high values of pollen concentration. Vegetation change controlled by human impact occurred from ca. 3,700 to 2,900 cal. yr BP, as indicated by a rise in Pinus and Polypodiaceae and by high sedimentation rate. Along with the late Holocene climatic cooling, human impact brought about the development of Pinus dominated open woodland with a fern (Polypodiaceae) understory in the Boseong area.

“…The Yellow Sea, separating Korea from central China, was entirely land during the last glacial period (Chung 2007), and the Changbai Mountains in northeast China can also be a geographic barrier, restricting free gene flow between Korean and northeast Chinese rodents. T. s. barberi is now contiguous, through the populations from the Jilin and Liaoning provinces in northeast China, with other populations of T. sibiricus, indicating that data from specimens of contiguous Jilin or Liaoning populations are essential for the taxonomic reexamination of T. s. barberi from the Korean peninsula.…”

Concordant Genetic Distinctness of the Phylogroup of the Siberian Chipmunk from the Korean Peninsula (Tamias sibiricus barberi), Reexamined with Nuclear DNA c-myc Gene Exon 2 and mtDNA Control Region Sequences

We reexamined Tamias sibiricus barberi from Korea by sequencing c-myc exon 2 and the mtDNA control region. In the c-myc exon, the monogenic T. s. barberi differed from the monogenic T. s. orientalis (nucleotide distance 0.48%; 3 variable sites at 168, 306, and 552), whereas T. s. orientalis was identical to T. s. sibiricus. In the control region, T. s. barberi differed from T. s. orientalis (distance 6.84%) and T. s. sibiricus (9.35%). We considered the concordant, extensive gaps between the phylogroup of T. s. barberi and other subspecies of T. sibiricus in the c-myc gene, control region, and cytochrome b gene to be evidence of a lack of intergradation through North Korea from T. s. barberi to T. s. orientalis. Our results, showing the genetic and morphological distinctness of T. s. barberi, support that this phylogroup is a distinct species.
