Over the past decades, anthropogenic disturbance of geological structures has been significantly documented in Slovakia, mainly driven by the national economy's demand for mining resources. Among these resources, brown coal, primarily mined in the Upper Nitra coal basin in the Prievidza district (Slovakia), has been essential. Mining activities around town of Handlov & aacute;, and villages of Ko & scaron;, C & iacute;ge & lcaron; and Sebedra & zcaron;ie, particularly at the C & iacute;ge & lcaron; coal mine, have induced several geological defects. These defects, characterised by large cracks and local landslides, disrupt the hydrogeological conditions, significantly impacting the soil water regime stability of the forest ecosystems in these damaged areas. This study investigates the variability and dynamics of the soil water potential in a mining-affected site (Ra & ccaron;kov laz) compared to an intact reference area (& Ccaron;ertove chodn & iacute;ky) between 2020 and 2022. Our findings suggest that mining activities could have substantial implications for the soil water regime and, consequently, the ecological stability of forest ecosystems.

In past decades, ash dieback has caused a rapid decline of European ash (Fraxinus excelsior) in temperate forests of Europe. Numerous studies focus on mitigating the negative impacts of ash dieback to forest ecosystems or identifying resistant genotypes. The role of natural selection toward genotypes withstanding ash dieback for ash regeneration has been less frequently studied with experimental means to date. This is, however, necessary in times of global change, because the preservation of ash in Europe's forests will depend, above all, on the adaptability of the future generations of ash trees. To quantify the extent and effects of ash dieback severity for ash regeneration we selected five forest stands moderately damaged and five forest stands highly damaged by ash dieback, in Schleswig-Holstein, Germany. We reciprocally transplanted naturally regenerated ash seedlings sampled in the field between these 10 sites. A shading treatment added to each half of the plots per site was meant to test for effects of altered light conditions in the herb layer due to canopy opening caused by ash dieback. With this approach, we tested seedling survival, performance and fungal infection for an interacting effect of origin and target site in regard to ash dieback severity and environmental factors over 2 years and recorded leaf traits (specific leaf area, leaf dry matter content) in the second year. Reduced light conditions under the shading nets had strong effects, influencing first year performance and infection probability as well as second year survival, growth and leaf trait characteristics. Soil conditions had only a marginal influence on transplanted seedlings. Transplantation direction between moderately and highly damaged sites affected infection marginally during the first year and survival as well as leaf traits significantly during the second year. Most notably, seedlings transplanted from moderately damaged to severely damaged sites exhibited the highest infection probability and lowest SLA, while seedlings transplanted vice versa were least likely to be infected and exhibited the highest SLA. Results hint at a first filtering effect by the ash dieback history of a forest stand and might indicate a transition from ecologically to evolutionary driven differentiation of ash seedling responses.

Background: an assessment of the environmental consequences of military actions was carried out from the perspective of the challenge to the peace formula. Methods: the information base of the research was the official resource of the Ministry of Environmental Protection and Natural Resources of Ukraine EkoZahroza and the materials of the State Environmental Inspectorate of the Polissia District regarding the calculations of the amount of damage caused by military actions. Results: it was determined that as of the 526th day of the military invasion (September 3, 2023), 34,119 units of Russian equipment caused the emission of 61,417 tons of pollutants into the atmosphere, the generation of 596,316 tons of waste, the spillage of oil products- 1,241 tons into the soil and 7 tons into the water. caused damage to the environment in the amount of 260.77 million UAH. The conducted surveys established that 93.8% of the surveyed schoolchildren and 100% of higher education students consider military actions on the territory of our state to be environmental crimes, among the components of the environment that suffer the most from military actions are soil and land resources and forest ecosystems. Conclusions: compared to the 127th day of the military invasion, the amount of destroyed military equipment increased by 6.9 times, emissions by 3.8 times, and waste by 6 times; losses- 3.8 times. There is an obvious need to assess all environmental risks caused by military actions, to apply an effective mechanism for compensation for damages and restoration of ecosystems. The optimistic attitude of the younger generation and youth regarding the possibility of improving the environmental situation in Ukraine after the end of military actions was noted. Measures to improve the state of the environment that were proposed by students testify to their environmental awareness and interest in environmental restoration, as well as the qualified training of ecologists by scientific and pedagogical workers.
