The socio-economic development of the country and any region is influenced by many factors, among which the most important role belongs to the demographic, in a generalized form representing the demographic situation. The demographic situation is usually understood as the demographic situation, the state of demographic processes, the composition and placement of the population at a certain time in a country or a particular region. Thus, the analysis of the demographic situation is necessary for understanding the main parameters of the population, trends in their dynamics, forecasting the number, demographic structure, demographic behavior of the population. Objective: to conduct a comparative analysis of official statistical data on demographic processes (statics and population dynamics) in the Moscow region (MO) for 2000-2015. Materials and methods: at the first stage, the collection and analysis of information and statistical sources were carried out, requests were sent to the Federal and territorial state statistics services of the Russian Federation (Rosstat, Mosobstat, MIAC MO). At the second stage, the data on demographic processes in the Moscow region were copied from the responses of Rosstat, Mosobstat, MIAC MO and from the websites of relevant organizations. Statistical analysis included calculation of simple arithmetic mean, percentage values, economic and demographic burden on the working population, demographic factors and the efficiency of population growth. Results and conclusions. The population of the Moscow region at the beginning of the XXI century continues to increase, but mainly due to migrants arriving from neighboring regions of the country and abroad. Males constitute 46.2% of the population and females 53.8% (2015). Boys are born more than girls by 6% and this advantage is maintained until the age of 30. And starting from the age of 35, the number of women begins to prevail over the number of men by 3.5%. This trend continues to 75 years and older. Age groups of the region's population are formed according to the regressive type: children - 15.9%; working-age population - 59.8%, and persons older than working age - 24.3% (2015). The economic and demographic burden of children and the elderly on the working population is more than 40%. The birth rate in the region increased by 76.7% from 2000 to 2015 and was higher than in 1990. Analysis of the total fertility rate indicates that in the Moscow region remains mononuclear family type (1-2-child family), ie there is no expanded reproduction of the population. In children, and especially in working age, the mortality rate is higher in men than in women. In men, the mortality rate reaches 41% of the total mortality at the working age. The number of women who died in working age is 4 times less than men. The natural increase in the population of the Moscow region for 15 years of the XXI century has a small but negative value, since the population is decreasing, and the increase in the population is mainly due to high migration.

Abstract This article provides an assessment of the demographic potential of the Baikal-Mongolian region, which unites the adjacent territories of the two countries. The cores of the research site are the urbanized territories of Irkutsk, Ulan-Ude and Ulan-Bator, and communications are railways and highways connecting the main centres. The demographic potential is characterized by the level and possibilities for the development of demographic processes and population structures, and mainly numerous quantitative characteristics of the population of the territory are used. The authors limited themselves to using quantitative characteristics of the demographic potential according to statistical data for 2019–2020 within the territories of the municipal districts and urban districts of the Irkutsk region, the Republic of Buryatia and aimags of Mongolia. Data on density and proportion of urban population reflect the size of the main urban areas. Data on demographic processes reflect the characteristics of the natural and migration movement of the population. Demographic structures are represented by the age structure and the demographic load of the working-age population, which is minimal throughout Mongolia and in the suburbs of Russian regional centres. Generalizing characteristics of demographic potential calculated from the average sum of individual indicators.

The black fly Simulium aureohirtum Brunetti (Diptera: Simuliidae) is geographically widespread and utilizes diverse habitats. Previous studies revealed high genetic diversity, suggesting that this species could be a species complex. In this study, we used mitochondrial cytochrome c oxidase II sequences to examine genetic structure and demographic history of S. aureohirtum in Thailand. High level of genetic variation was observed due to the existence of genetically divergent lineages (A, B, and C). Lineages A and C were geographically widespread, while lineage B was geographically restricted to the eastern part of Thailand. The geographic localization of lineage B suggested limitations in gene flow, which is most likely a result of ecologically different habitats. Large genetic differences between individuals of lineages A and C, but geographically sympatric distributions of the members of these lineages, are considered to represent an admixture of the populations that have evolved allopatrically. Historical environmental change during the Pleistocene glaciations is possibly the factor that drove the lineage divergence. Population demographic history analyses revealed recent population expansions in the three lineages dating back to the last glaciations. These observations further highlight the significance of the Pleistocene climatic change on current genetic structure and diversity of living organisms of the Southeast Asian mainland.
