“…() showed that the gold‐spotted pond frog Rana plancyi chosenica has two genetically diverse clades in Korea. Three cryptic sub‐clades were identified for Korean salamanders (genus Hynobius ) based on geographical differences (Baek et al ., ). Three distinct phylogroups were also found for the Siberian chipmunk Tamias sibiricus of South Korea from mtDNA cytochrome b (cyt b ) sequences (Lee et al ., ).…”

Phylogeography ofKorean raccoon dogs: implications of peripheral isolation of a forest mammal inEastAsia

The Korean Peninsula is a problematic place for tracing the evolutionary history of many East Asian species because of its location on the eastern edge of the Eurasian continent. This peninsula probably experienced peripheral isolation as one of several possible Pleistocene refugia. Historical population fluctuations and peripatric speciation of vertebrates in the Korean Peninsula are poorly understood. As an endemic species in East Asia, the raccoon dog Nyctereutes procyonoides is an appropriate model for describing the evolutionary history of mammal species in the Korean Peninsula. Therefore, we used mitochondrial cytochrome b sequences of raccoon dogs from Korea,

“…Moreover, the Korean Peninsula is divided by geographical landscape barriers, leading to the emergence of several clades within Pelophylax chosenicus ( Min et al, 2008 ), Hynobius spp. ( Baek et al, 2011 ; Min et al, 2016 ) and Dryophytes japonicus ( Dufresnes et al, 2016 ), a consequence of allopatric divergence.…”

The effects of ice ages on speciation have been well documented for many European and North American taxa. In contrast, very few studies have addressed the consequences of such environmental and topographical changes in North East Asian species. More precisely, the Korean Peninsula offers a unique model to assess patterns and processes of speciation as it hosts the northern- and eastern-most distribution limit of some widespread Asian taxa. Despite this, studies addressing phylogeographic patterns and population genetics in the peninsula and surrounding countries are few and studies for most families are lacking. Here we inferred the phylogenetic relationships of the common toad (Bufo gargarizans) from South Korea and their North East Asian counterpart populations, based on mitochondrial data. Korean B. gargarizans GenBank BLASTs matched few individuals from nearby China, but the presence of a Korean clade suggests isolation on the Korean Peninsula, previous to the last glacial maximum, linked to sea level resurgence. Molecular clock calibrations within this group were used to date the divergence between clades and their relationship to paleo-climatic events in the area. Lack of genetic structure among South Korean populations and strong homogeneity between the Korean and some Chinese localities suggest weak isolation and recent expansion. Geographical projection of continuous coalescent maximum-clade-credibility trees shows an original Chinese expansion towards the Korean Peninsula through the Yellow Sea circa two million years ago with colonisation events dating circa 800 thousand years ago (K. y. a.). Following this colonisation, the data point to outgoing Korean Peninsula dispersal events throughout different periods, towards the North through land, and West through land bridge formations over the Yellow Sea during sea level falls. In accordance, demographic analyses revealed a population expansion in the Koran Peninsula circa 300 K. y. a., likely attributed to glacial cycle fluctuations.

“…Over two decades, several new Hynobius salamander species have been discovered on the Korean Peninsula, a very small area on the southern tip of East Asia (Kim et al 2007;Baek, Lee, Lee et al 2011a;Baek, Lee, Song et al 2011b;Min et al 2016). Hynobius unisacculus is the fourth Hynobius species officially recorded on this peninsula after H. leechii, H. quelpaertensis and H. yangi (Baek, Lee, Lee et al 2011a;Baek, Lee, Song et al 2011b;Min et al 2016). Upon a phylogenetic tree reconstructed based on cyt b and 12S rRNA, this species formed a single cluster with H. quelpaertensis among these three previously known Hynobius species (Baek, Lee, Lee et al 2011a;Baek, Lee, Song et al 2011b;Min et al 2016).…”

Hynobius unisacculus is a hynobiid salamander species found only in a limited area at the southernmost part of the Korean Peninsula. Here, we characterized the complete mitochondrial genome of this species that was used to identify the phylogenetic relationship with other Hynobius species. The whole sequence was 16,411 bp and included 13 protein-coding genes, 2 ribosomal RNA genes, and 22 transfer RNA genes. The gene arrangement was completely identical to those observed in other Hynobius species. Upon robust phylogenetic tree reconstructed based on 13 protein-coding genes, Hynobius species living on the Korean Peninsula showed close phylogenetic affinity; H. unisacculus and H. quelpaertensis formed a cluster that was the sister to the cluster of H. leechii and H. yangi.
