Oyundelger Khurelpurev,Martin Pfeiffer 국립중앙과학관 2017 Journal of Asia-Pacific Biodiversity Vol.10 No.3
The Altai Mountains located in western Mongolia comprise diverse habitats including forest, mountain steppe, dry steppe, semidesert, and desert. This study used advanced statistics to examine how diversity and species composition of beetle communities depend on vegetation pattern and environmental factors along an ecological gradient from steppe to desert. Our study included the beetle families Tenebrionidae, Carabidae, Curculionidae, and Coccinellidae, which account for the majority of the known beetle fauna in the area. The most abundant Coleoptera in all plots were Harpalus limbaris, Corsyra fusula, and Anatolica cellicola; otherwise, we caught a large number of rare species. The beta diversity of communities was correlated with distance between plots. Species richness of beetles was positively impacted by plant cover and correlated negatively with rising temperatures, whereas Shannon diversity of beetle communities was significantly higher in areas with higher precipitation. Distribution and community composition of Coleopterans were governed by environmental factors, especially plant diversity, mean annual temperature, and summer precipitation, as revealed by redundancy analysis.

Contribution to the knowledge on the flora of Munkhkhairkhan mountain area, Mongolia
Oyuntsetseg Batlai,Baasanmunkh Shukherdorj,Oyundelger Khurelpurev,Munkhzul Oyunbileg,김재영,조형준,Batkhuu Nyam-Osor,정규영,최혁재 국립중앙과학관 2017 Journal of Asia-Pacific Biodiversity Vol.10 No.4
The Munkhkhairkhan mountain area is a unique highland ecosystem with a diverse regional alpine flora. This mountain habitat is located at the overlap of different floristic regions: on its western side Kazakhstan–Turan flora is dominating, and on the eastern side East Asian flora is observed. It is known that the whole area has a large number of endemics and rare plant species, because of its specific, harsh habitat conditions. Therefore, the flora of different habitats in the Munkhkhairkhan mountain needs to be investigated and properly protected. Munkhkhairkhan National Park has been founded in 2006, and our survey concentrated on the protected area as well as the surrounding areas of the mountains. All recorded species in this study were based on the collected voucher specimens. Conservation status for remarkable species was also reviewed based on the literature. As a result, we recorded 40 families, 150 genera, and 267 species of vascular plants, including four endemic and 34 subendemic species and 15 species' new distribution notes. Around the Munkhkhairkhan mountain, 16 very rare, 21 rare, eight endangered, and two near threatened species are growing, indicating the high conservation value of this area and the necessity for research.

Contribution to the knowledge on the flora of northern Mongolia
Shukherdorj Baasanmunkh,Batlai Oyuntsetseg,Khurelpurev Oyundelger,Khurelbaatar Khaliunaa,Magsar Urgamal,Nyam-Osor Batkhuu,Takashi shiga,정규영,최혁재 국립중앙과학관 2019 Journal of Asia-Pacific Biodiversity Vol.12 No.4
Field surveys were conducted in the northern part of Mongolia in 2017 and 2018. Vascular plants floristicdata are based on collections from the study area, and more than 800 new collections are made in thisstudy. In total, 289 taxa (8 subspecies and 6 variates) were identified, representing 173 genera from 60families of vascular plants. The families most diverse in species were Rosaceae with 28 taxa, followed byRanunculaceae (25 taxa), Asteraceae (19 taxa), and Fabaceae (19 taxa). The largest genera were Salix with11 species, followed by Viola (9 species) and Carex (9 species). Thirty-seven taxa are newly recorded forMongolian Dauria (8), Khangai (8), Khentei (4) and Khuvsgul (17) regions. Several threatened specieswere found in the field area. We provide photographs and distribution maps for species of Cypripedium(C. calceolus L., C. guttatum Sw., C. macranthos Sw., and C. ventricosum Sw.). In addition, Campanula cervicariawas newly recorded for the flora of Mongolia.

Fritillaria dagana Turcz. has a restricted global distribution, occurring only in southern Siberia andnorthern Mongolia. Concerning its restricted distribution and endangered conservation status, we aimedto forecast its current and future suitable habitats as well as distribution shifts for 2050 and 2080. TheMaxent model with different scenarios (representative concentration pathway 4.5 and representativeconcentration pathway 8.5) was used to analyze 113 georeferenced records of F. dagana using 19bioclimatic factors from the WorldClim database. As a result, the amount and variance of precipitationand temperature, together with elevation, were shown to be the most significant factors affecting thespecies’ distribution. In particular, precipitation during the plant growing season had the greatest impact(55.2% variability) on the species distribution. Climate change was expected to cause a minor shift in thedistribution of suitable habitats toward the north and an increase in habitat continuity, indicating thatthe climate will become more favorable for the growth of species and in the future. The species’ highlysuitable area will remain primarily concentrated in its current potential distribution area in centralSiberia (around Lake Baikal). The species’ conservation status was determined to be near threatened,emphasizing the great relevance of facilitating proper conservation measures for F. dagana.
