A webcam was installed on the shore of the South-Eastern Baltic (Kaliningrad Oblast, Russia) to monitor the beach dynamics and beach-cast (BC) daily from November 1, 2019, to October 31, 2020. The ...beach was formed not the whole year (77%). The most frequent BC residence time was one day (1–21, 4.1 on average, and 1–19, 4.3 on average days to the west and east of the groin, respectively). The BC consisted primarily of algae. Fresh BC occupied smaller area, and its layer was thicker than that of long-discarded and trampled BC. The specific amount of material (per m2) in a fresh BC was 3.7 times higher in volume and 2.6 times higher in weight than in long-discarded and trampled BC. For fresh and old BC, the specific volumes were 63 and 17 l per m2, respectively, and the specific masses were 48 and 18 kg per m2, respectively.
•First video-monitoring the beach (B) and beach-cast (BC) in South-Eastern Baltic•One-year data showed seasonal variability of B and synoptic for BC presences.•Most frequent BC residence time lasted 1 day; it ranged 4.1–4.3 days on average.•Fresh and old BC specific volumes are 63 and 17 l per m2 of the beach-cast.•Fresh and old BC specific masses are 48 and 18 kg per m2 of the beach-cast.
New material of Dolichopodidae has been recently collected in the Khingan Nature Reserve, Amurskaya Oblast, which includes 14 species (all species are new for the Reserve). In total, 86 species are ...reported in this Region, which apparently make up 45–50% of actual Dolichopodidae regional fauna. Amblypsilopus aff. bouvieri (Parent, 1927), Chrysotimus spinuliferus Negrobov, 1978, Gymnopternus pseudoceler (Stackelberg, 1933), Poecilobothrus flaveolus (Negrobov et Chalaya, 1987) and Sympycnus changaicus Negrobov, 1973are recorded from Priamurye for the first time. This paper also provides the distribution pattern for each collected species. A check-list of Dolichopodidae species known from Amurskaya Oblast is provided.
The purpose of the article is to determine the most significant causes of population decline in the regions of the Russian Arctic. The object of the study was the urban population of the subjects of ...the Russian Arctic. The concept of a shrinking city, which has received various interpretations both in foreign and domestic scientific thought, was chosen as a theoretical framework for understanding the problem. In this article, the shrinkage of cities is understood as a cumulative result of economic and demographic factors that cause population decline in the form of natural loss and migration outflow. On the basis of statistical data, a steady demographic decline was recorded in the cities of the subjects of the Russian Arctic. This made it possible to confirm the validity of the use of this concept in relation to these territories. Based on the materials of domestic and foreign studies, the most general, systemic factors of population decline in the regions of the Russian Arctic were identified, such as: the historical context and the policy of Soviet industrialization, the specifics of the local (regional) identity of the inhabitants of the northern territories, global demographic trends. At the empirical level, a more detailed analysis of the subjective perception of the reasons for the outflow of the population from the Murmansk Oblast, reflected in the public discourse of the participants of the online community of the city of Murmansk in the social network VKontakte, was carried out. The initial analysis base included posts and comments of the community for 20212022 (a total of 23.817 posts and 926.583 comments), the target sample included 268 posts and 2621 comments. Open and axial coding techniques were used to identify three groups of urban development issues as causes of the outflow of population from the region: 1) natural and climatic conditions, 2) quality of life, 3) prospects for the development of the city. Quantitative analysis of the number of comments (under posts) and likes (under comments) allowed us to identify the most significant and persistent problems, which, of course, are of increased interest to representatives of municipal and regional authorities.

The level of positive migration aspirations of the population is determined by the unfavorable socio-economic environment and ineffective management of territory development, in particular the level ...of deprivation, including labor, security and living conditions. The paper aims to assess the impact of different components of deprivation on the spread of migration aspirations and create the landscape of a territory migration capacity. The methodological tool of the study is a sociological survey (a case study of Lviv Oblast, Ukraine) using a questionnaire (self-administration), which covered more than 500 people. Processing of results is carried out using SPSS software. The results of the sociological survey across migration vectors show the cause-effect relation between positive external aspirations and deprivation components. According to the assessment, the EU countries vector (72.0%) has the highest level of positive migration aspirations by income deprivation, and domestic migration vector – the lowest level (41.0%). The highest deprivation levels among socio-economic, environmental, and medical-demographical conditions for ineffective management of Lviv Oblast was detected for educational services with the level of 3.6 out of 5 possible, moderate level – for living and environmental conditions (2.9 each), and the lowest one for medical services (2.7). The spread of deprivation components at the territory according to the level of positive migration aspirations analysis shown that the highest deprivation levels in Lviv Oblast are peculiar to components such as the quality of medical services (43.4%), income (36.5%), and living conditions (35.1%). This study is of practical value for forming landscape of territory migration capacity including weighed migration aspirations and socio-economic deprivation levels.
