Ecological and biological features of Triglochin maritima L. in the biotopes of the littoral zone with different degree of flooding on the coast of the White Sea

The study of Triglochin maritima L. was carried out on the Pomor (western) coast of the White Sea, in the Republic of Karelia (64°22'81"N, 35°93'14"E). Morphological analysis of aboveground and underground parts of the clones was performed on virginal plants. Anatomical analysis of leaf sheaths of the current year shoots, rhizomes and adventitious roots was carried out. The viability of pollen was assessed by determining the relative share of normally developed and malformed pollen grains. The content of heavy metals was determined in the soil, sea water and plant samples. The study was carried out on a model transect in the littoral zone on three test plots representing the lower littoral; the middle and the upper littoral zones. Adaptation to wave and storm impact was manifested in a well-developed system of underground organs. In the lower littoral, underground part surpasses the aboveground vegetative organs in terms of the mass and the formation of mechanical tissues. This allows the plants to anchor stronger in the substrate. Pollen analysis confirmed the adaptability of T. maritima plants to the conditions of the lower littoral by a high percentage of normal and, consequently, fertile pollen, which ensures sexual reproduction of the species. T. maritima can be considered as a Fe hyperaccumulator as the plant accumulates very high levels of Fe (22–34 g kg-1), especially in the lower and middle littoral zones, both in underground and aboveground organs. The ability of T. maritima plants to actively deposit metals was revealed on the basis of the coefficient of biological absorption of metals and makes it possible to suggest potential possibility of using the species in phytoremediation technologies on coastal territories

Образовательный потенциал блогосферы как фактор формирования правовой культуры человека

Introduction. The relevance of the study is caused, on the one hand, by the blogosphere’s dynamic development, and, on the other, by insufficient theoretical understanding of the blogosphere and its role in the formation of the legal culture of modern man. The purpose of the study is the identification of the educational resource of the blogosphere, its relevance, and justification of the need for its use in the formation of the individual’s legal culture. Materials and research methods. The variety of research methodologies related to the consideration of the blogosphere’s educational resource as a factor in the formation of legal culture is due to the variety of approaches – cultural-historical, contextual, competency building, personality-centered, aimed at achieving the study goal. Research result. As a result of monitoring the list of hashtags that we compiled, correlated with the theoretical construct "legal culture", conducted according to search queries in social networks, platforms and applications – VKontakte, Twitter, Instagram, YouTube, TikTok, statistics were obtained for the indicators "mention", "engagement", "sentiment", the TOP-10 hashtag rating was built. The data obtained indicates a high demand among users for legal content, legal information, and effective behavioral practices in legal situations. It is justified that interest in legal educational content in the blogosphere is associated with the current situation of people's life, characterized by variability, non-standard, uncertainty, active development of law-making practice, which involves continuous updating of legislation’s knowledge. Discussion of results and conclusions. The media sphere is represented by many environments, one of which is the blogosphere as a dynamically developing Internet space with educational potential. This potential is significant in the formation of the legal culture of the individual, its cognitive and activity components. © 2020 LLC Ecological Help.
