Technogenic reservoirs, i.e., sand quarry lakes, appear when sand is extracted under the water column by dredgers or as a result of flooding of quarries. Studies of such reservoirs in the territory of Small Polissia (Ukraine) have shown that the devastated shoreline is like a neo-ecotope formed in the ecotone zone between the water environment of such reservoirs and natural areas upon completion of their operation. Changes in the ecotope within this zone lead to the formation of ecological niches with a set of new specific factors characteristic of aquatic and near-shore vegetation. It has been determined that the fundamental niche of macrophytes in the littoral area of sand quarry lakes in the conditions of Small Polissia is determined by the following parameters: illumination 2500-90000 lux; depth 0–5 m; and trophicity (humus content) – 0-5 %. The realized niches differ for plants of different ecological groups and make up about 50 % for helophytes, about 20 % for pleistophytes, and about 70 % for hydatophytes of the fundamental niche of aquatic vegetation. The volume of space in which the niches of all types of macrophytes in the technogenic lakes of Small Polissia overlay is 10%. The maximum overlay of niches is characteristic of areas covering a combination of factors in terms of illumination (in summer) 15000-90000 lux and depths of 1.3–2.8 m, which creates conditions for the formation of three-tiered phytocoenoses. The niche of submerged plants is the largest, which indicates their highly competitive potential, which is limited mainly by the illumination parameter. Under such conditions, the rapid development of submerged vegetation in the future may lead to the accumulation of its biomass and bogginess, which will limit the use of sand quarry lakes for recreational and other types of nature management. Phytomeliorative tree planting around sand quarry lakes is proposed to regulate illumination as a parameter of the ecological niche of submerged plants. Doi: 10.28991/HEF-2022-03-04-02 Full Text: PDF

The article presents the results of the experimental study targeted at the scientific substantiation and experimental verification of the methodology of the future biology teachers’ ecological competence development. It is grounded and proved that ecological education resulting in ecological competence is an integral part of education for sustainable development. In order to integrate sustainable development education into the future biology teachers’ training, the methodology for the ecological competence development has been suggested. The methodology involves the environmentalization of the educational content and the use of a modular object-oriented dynamic learning environment. A pedagogical experiment was conducted in order to determine the effectiveness of the methodology of future biology teachers training for the implementation of sustainable development ideas in ecological education. Four hundred and twenty-seven students participated in the experimental study. Control and experimental groups of students were allocated for conducting the experiment. In experimental groups the author’s methodology was implemented. The experimental data were processed using mathematical statistics. As a result of the generalization of the results of the study, it was found that in the experimental groups, the percentage of students with high and medium levels of ecological competence increased, and with low levels – decreased compared to the control groups. This testifies to the effectiveness of the future biology teachers’ ecological competence development.

The current stage in the development of pedagogical education in the world is characterized by a special intensity and scale of transformations due not only to the urgent tasks of forming a young personality, but also to the involvement of the education system in the world integration processes taking place in the context of informatization and globalization. The purposeful acquisition of knowledge, skills and abilities by future biology teachers, an orientation towards the development, development and implementation of effective mechanisms for its formation is an important component of education. The global educational community is faced in 2020 with a global challenge caused by the pandemic caused by the spread of the SARS-CoV-2 coronavirus. The governments of most countries were not ready for such a large-scale pandemic; their practical measures were formed on a situational basis. To counter the spread of COVID-19, educational institutions have been temporarily closed almost all over the world. The purpose of the article is to study the features of the implementation of the distance education system in the process of teaching students - future biology teachers, including the study of the main advantages and disadvantages of this process. For this, the methods of theoretical research of specialized literature were used.

The article considers the changes in some agrochemical parameters and the content of plumbum in the soil cover of a medium-sized urban ecosystem after the introduction of quarantine measures in connection with the Covid-19 pandemic. It has been determined that the blocking of anthropogenic activity did not affect the content of humus. There were changes in soil pH, which led to the transition from an alkaline reaction to a neutral one. The amount of fertilizer elements (NPK) in the soil in the post-quarantine period has been increased. The content of the mobile (active) form of plumbum within the city has been halved on average. In general, the impact of quarantine from Covid-19 on the condition of the soil cover as well as on air and surface water can be preliminary considered as positive. Doi: 10.28991/HIJ-SP2022-03-04 Full Text: PDF
