“…Siberian roe deer from Jeju Island (SKJ) showed the lowest level of genetic diversity in this study and compared to other species. This is presumably due to its geographical isolation (Jo, Kim, Choi, & Oh, ) and a small founder population originally colonizing Jeju Island. The Mainland Korea (SKM) population showed relatively high haplotype diversity and low nucleotide diversity among the populations sampled.…”

“…High nucleotide diversity of Siberian roe deer at the northern periphery of its geographical range in Yakutia (RYA) may belong to the former scenario as it was reported that the population there is a mixture of two subspecies, C. p. pygargus and C. p. tianschanicus (Argunov, 2013;Boeskorov & Danilkin, 1998 in this study and compared to other species. This is presumably due to its geographical isolation (Jo, Kim, Choi, & Oh, 2012) and a small founder population originally colonizing Jeju Island. The Mainland Korea (SKM) population showed relatively high haplotype diversity and low nucleotide diversity among the populations sampled.…”

Current understanding of phylogeographical structure and genetic diversity of Siberian roe deer remains limited mainly due to small sample size and/or low geographical coverage in previous studies. Published data suggest at least two phylogroups: western (Ural Mountains and Western Siberia) and eastern (east from lake Baikal, including the Korean peninsula), but their phylogenetic relationship remains unclear. Combined sequences of cytochrome b (1140 bp) and the mtDNA control region (963 bp) were analyzed from 219 Siberian roe deer from 12 locations in Russia, Mongolia, and South Korea, which cover a large part of its range, to assess genetic diversity and phylogeographical status. Special emphasis was placed on the demographic history and genetic features of central, peripheral, and isolated populations. Results of median‐joining network and phylogenetic tree analyses indicate that Siberian roe deer from the Urals to the Pacific Ocean are genetically diverse and that geographical distribution and composition of haplogroups coincide with previously described ranges of the subspecies Capreolus pygargus pygargus and Capreolus pygargus tianschanicus. We found that peripheral populations in the northwestern parts of the species range (Urals), as well as the isolated population from Jeju Island, are genetically distinct from those in the core part of the range, both in terms of genetic diversity and quantitative composition of haplogroups. We also found that northwestern (Urals) and northern (Yakutia) peripheral populations share the same haplogroup and fall into the same phylogenetic clade with the isolated population from Jeju Island. This finding sheds light on the taxonomic status of the Jeju Island population and leads to hypotheses about the discordance of morphological and genetic evolution in isolated populations and specific genetic features of peripheral populations.

“…Many studies reported the disturbance of regeneration of tree species by ungulate browsing around the world (Wilson 1969, Gill 1992, Waller and Alverson 1997, Potvin et al 2003, Rooney and Waller 2003, Senn and Suter 2003, Weisberg and Bugmann 2003, Cote et al 2004, Tsujino and Yumoto 2004, Pepin et al 2006, Takatsuki 2009, Hidding et al 2012, Nagaike et al 2014Cutini et al 2015, Swiss Federal Institute for Forest 2015; a few studies were carried out on the dynamics and the other ecological issues of roe deer in Korea (Kim and Kim 2001, Kim 2006, Kim and Hong 2006, Kim et al 2007a, Jeon and Kim 2011, Jo et al 2012, 2013, Kang 2013. In addition, studies on the dynamics of forest stands indicated that competition with other species of understory vegetation such as dwarf bamboo (genus Sasa) can interrupt the establishment of the seedlings of the natural tree species at forest stands of the world (Nakashizuka 1988, Peters et al 1992, Abe et al 2001, Taylor et al 2004, 2006, Doležal et al 2009, Song et al 2014.…”

Background: Natural regeneration of seedlings as well as saplings of Korean fir has been significantly impacted by the browsing from the early stages of their development, potentially, by roe deer for the last two to three decades at the study site since late 1980s. This study was carried out to investigate current status of the disturbance in the seedling development of Korean fir (Abies koreana) on Mt. Hallasan, Jeju Island, Korea.Methods: Field survey was carried out during June and August in 2016 to measure the characteristics of study site and understory vegetation by applying systematic sampling to 125 plots of 5 m × 5 m quadrat located on eastern slope of the mountain. Correlation and regression analyses were applied to the variables quantified from the data sets using the SAS software.Results: No saplings with their diameters at breast heights smaller than 5.0 cm were found at the study site indicating the serious disturbance in the natural regeneration of Korean fir at the study site. No seedlings with their heights taller than 36.0 cm were found at the study site indicating even more serious disturbance during earlier stage of the natural regeneration of Korean fir at the study site. A total of 616 individuals of the seedlings of Korean fir were found at 54 out of 125 sampling plots. One hundred thirty-eight seedlings (22.4%) out of 616 individual seedlings have the vestiges for being grazed, potentially, by roe deer. Conclusions: Due considerations should be given to the effects of browsing of the seedlings by roe deer to promote the natural regeneration of Korean fir, ultimately to restore Korean fir. It is needed for the managers of the forest to install fences around the forest area. Exclosure experiments as well as enclosure experiments of different densities of browsing should be carried out. In addition, treatment with different densities of Jeju dwarf bamboo should also be included in the experiment on Mt. Hallasan National Park, Jeju Island, Korea.

“…This diminutive, charming chipmunk became a preferred pet of the Korean public and visitors to Korea to the extent that it was an important animal export of Korea until the 1980s (Yoo 2000). Unfortunately, the proclivity for T. sibiricus as a pet resulted in trapping, exporting, and transplanting large numbers beyond its natural distribution, such as Jeju Island in Korea and countries in Europe and Japan, except for Hokkaido Island with an indigenous population (Chapuis et al 2009;Oshida 2009;Jo et al 2012). Siberian chipmunks remain a highly merchandized animal in pet shops in Korea today and is an emblematic animal for "clean nature" or environmental quality in Korea.…”

Compared to European countries where the Siberian chipmunk (Tamias sibiricus) is an invasive species, there is a paucity of information on the ecology and natural history of Korean populations. T. sibiricus is a native species with large populations in Korea. We conducted field research during January to December 2012 in a forest habitat located in Hongcheon-gun, Gangwon-do (37°45′ 50″ N, 127°50′ 52″ E) in central Korea. We used both radio-tracking and capturerecapture techniques to determine home range size and nocturnal shelters. We also excavated and measured burrows and analyzed food items from caches. The mean 95 % of kernel home range size for males was 16,586 m 2 (100 % of MCP= 14,129 m 2 ) and 4,432 m 2 (100 % of MCP=4,512 m 2 ) for females. Burrow systems typically had a nest, latrine, and food caches with tunnels. Nocturnal shelters were uncommon and co-habiting for summer sleeping and winter torpor were also rare. The primary food items in caches were chestnuts (77.0 %), Mongolian oak acorns (12.1 %), and bird's-foot trefoil (2.1 %). The information on the ecology and natural history of the Korean subspecies of Siberian chipmunks reported in this research shows significant differences from the ecological information for the subspecies in Hokkaido Japan.
