Saussurea dorogostaiskii Palib. (Asteraceae) is a critically endangered medicinal plant in Mongolia and Russia. We studied the genetic variation of S. dorogostaiskii from three mountains of northern Mongolia. The genetic profile was assessed in 70 individuals from eight populations using five inter-simple sequence repeat markers, producing 53 loci with 96.4% polymorphism across all bands. Shannon’s index (I) and Nei’s gene diversity (H) value at the species level of S. dorogostaiskii are 0.25 and 0.17, respectively. An AMOVA showed high genetic variation among the populations (22% of populations and 32% of mountains), consistent with the high genetic differentiation (GST = 0.49) and low gene flow (Nm = 0.51) in S. dorogostaiskii populations. Eight populations were clustered into two groups, corresponding to their geographic locations. The low within-population genetic diversity and high genetic differentiation among S. dorogostaiskii populations factor into their endangered designation. This genetic analysis reveals that all populations are equally threatened, and community-based conservation is appropriate for these species.
Snowpit Record from a Coastal Antarctic Site and its Preservation of Meteorological Features

Polar snow pits or ice cores preserve valuable information derived from atmosphere on past climate and environment changes. A 1.57 m snow-pit record from the coastal site (Styx Glacier) in eastern Antarctica covering the period from January 2011 to January 2015 was discussed and compared with meteorological variables. The dominant contribution of the deposition of sea salt aerosols due to the proximity of the site to the ocean and processes of sea ice formation was revealed in the ionic concentrations. Consistent seasonal peaks in δ<SUP>18</SUP>O, δD, MSA, nssSO₄<SUP>2-</SUP>, and NO₃<SUP>-</SUP> indicate the strong enhancement of their source during warm periods, whereas the sea salt ions (Na<SUP>+</SUP>, K<SUP>+</SUP>, Mg<SUP>2+</SUP>, Ca<SUP>2+</SUP>, Cl<SUP>-</SUP> and totSO₄<SUP>2-</SUP>) exhibit a distinct distribution. Monthly mean δ<SUP>18</SUP>O positively correlates with the air temperature record from automatic weather station located in the main wind direction. Despite the shortness of the record, we suspect that the slight depletion of the isotopic composition and lowering of the snow accumulation could be related to the cooler air temperature with the decrease of open sea area. Consistency with previous studies and the positive correlation of sea salt ions in the snow-pit indicate the relatively well preservation of snow layers with noticeable climate and environmental signals (e.g. changes in sea ice extent or sea surface temperature). We report a new snow-pit record, which would be comparative and supportive to understand similar signals preserved in deeper ice cores in this location.

Since the beginning of human existence in Mongolia, during the late Neolithic period and the Bronze Age, education and training within the nomadic civilization has completely changed to a deliberate and conscious activity, and education has entered a new stage. The first forms of writing were emerging. Also, the new content and forms of knowledge, abilities, and attitudes that emerged from the first state-like states were actively developing, which accelerated the development of education. However, reviewing the primacy view that “the first state on the territory of Mongolia was the Hun/Nu/, and during the Huns, history and historical science were established”, which is firmly present in the world and in the history of Mongolia and in the minds of citizens. Summarizing the works of foreign and domestic researchers, which is said to be the first state on the territory of Central Asia and Mongolia, “Whether other state-like states existed before the Huns” on the territory of the present Mongolian ethnic group, “Historical records were created during the Huns and historical records The main goal of this research is to correct the view that “the origin of science has been established” and determine the date of the existence of states in Mongolia. From this point of view, not only historical education, but in general, how education and training was conducted among the ancient Mongolian ethnic groups, when did it start, and what was passed down to the current Mongolians, the problem of the origin and development of Mongolian traditional education, etc. is certain to be established. Then, the view that history education began to develop systematically from the time of the Hun dynasty will undoubtedly change.
