Scots pine (Pinus sylvestris L.) spans most of Eurasia, yet southern and mountainous populations may retain distinctive genetic components shaped by long-term isolation and complex postglacial dynamics. We genotyped 186 trees from four Scots pine stands in Armenia (AM1-AM4) and reference stands from Germany, Russia and Montenegro with the PiSy50k SNP array and integrated these data with published European array datasets from Finland, Poland and the Baltic region. After quality checks and conservative SNP filtering, 627 individuals from 47 populations and 3659 SNP loci were retained. Within-population diversity was generally high; Armenian stands AM2–AM4 were among the most diverse, whereas AM1 showed reduced diversity and the highest differentiation relative to the remainder of the dataset (FST vs. rest = 0.0047). Direct pairwise F_ST and hierarchical AMOVA confirmed pronounced heterogeneity among Armenian stands, with AM1 the most differentiated stand, AM2 and AM4 closest to the broader Eurasian background, and AM3 intermediate. Principal component analysis (PC1 = 1.42%, PC2 = 0.76%) again separated AM1 strongly from all non-Armenian samples, while AM2 overlapped with the central/eastern European cluster and AM3 and AM4 combined continental-like and AM1-like individuals. Structure-like inference with LEA/sNMF showed a broad cross-entropy plateau from approximately K = 4 to K = 6; we therefore use K = 5 as a practical summary, which highlighted a dominant AM1-associated ancestry component and variable continental admixture in AM2–AM4. KING kinship estimates provided little evidence for within-stand family clustering in Armenian stands; no second-degree-or-closer pairs were observed in AM1–AM4. Together, the results reveal pronounced heterogeneity among Armenian Scots pine stands and identify AM1 as a highly differentiated but unresolved genomic component, providing a genomic baseline to support conservation planning, provenance evaluation and the management of forest reproductive material in the Lesser Caucasus.

Decorative wooden floorings in heritage interiors require restoration strategies that balance material authenticity, technical reliability, and environmental sensitivity. This study presents a conservation-oriented restoration of a historic parquet floor in the Monastery at Kalwaria Zebrzydowska (Lesser Poland Voivodeship, Poland), originating from the late nineteenth and early twentieth centuries, and focuses on the role of structured risk analysis in technological decision-making. A systemotechnical framework was applied to analyse the restoration as a sequence of interrelated stages governed by material, structural, environmental, technological, and organisational subsystems. Qualitative and semi-quantitative risk classification was integrated with diagnostic investigation, workshop renovation, subfloor reconstruction, reinstallation, and post-intervention monitoring. The results show that dominant risk categories shift across stages and can be progressively reduced through targeted mitigation measures, particularly those addressing moisture variability, material compatibility, and organisational coordination. Early-stage diagnostics combined with active microclimate control proved critical to process reliability and long-term performance, enabling the retention of approximately 85% of the original wooden material. The findings demonstrate the broader applicability of phase-based, risk-informed decision-making in heritage conservation, offering a transferable framework for sustainable restoration of historic wooden floors across diverse cultural and climatic contexts.

Chlorophylls and carotenoids are key plant metabolites involved in photosynthesis, stress responses, and antioxidant activity. This study aimed to examine intrapopulation variability in Melica uniflora Retz. (wood melick), focusing on chlorophyll and carotenoid content in relation to the developmental stage and environmental conditions. Research was carried out over three consecutive years (2021–2023) in the Ślęża Massif near Sobótka, Lower Silesia, Poland. Leaf blades samples were collected annually from ten natural forest sites at two time points: summer (July) and autumn (October), and analyzed for chlorophyll a, chlorophyll b, and total carotenoids using spectrophotometry. Statistical analyses, including ANOVA, were used to assess the effects of year, harvest time, and site on pigment concentrations. The average (±SD) pigment content in M. uniflora was 1.44 ± 0.73 mg∙g⁻¹ DM for chlorophyll a, 0.67 ± 0.40 mg∙g⁻¹ DM for chlorophyll b, and 0.46 ± 0.28 mg∙g⁻¹ DM for total carotenoids. Among the factors studied, year and developmental stage had the strongest statistically significant influence on chlorophyll and carotenoid levels, while site-specific differences contributed to intrapopulation variability to a lesser extent (p < 0.001). Interestingly, the first year of the study showed higher average pigment levels across both harvest times. Summer-collected plants had higher concentrations of all pigments than those collected in autumn. Differences among sites further indicated intrapopulation variability within this species. These findings provide new insights into the natural variability of photosynthetic metabolites in forest grasses and may serve as a reference for studies on the adaptive and biochemical responses of woodland plant species to environmental factors.

The heritage of John Paul II (JP2), a widely recognised religious and political leader, remains an important part of Polish heritage. However, the values and teachings he embodied appear to be increasingly disconnected from the younger generation. This study aims to assess whether the memory of JP2 today functions as an internalised heritage among young adults in Poland (aged 29–35) or whether it serves primarily as a symbolic point of reference. Drawing on Marianne Hirsch’s concept of post-memory, the study conducted a representative survey (n = 500) of young adults in Poland. The study constructed an empirical post-memory indicator of JP2’s heritage, incorporating information on the pope and own religiosity. Findings show that the memory of JP2 is primarily transmitted through family, school and traditional media. Other institutional and non-institutional channels of communication play a lesser role. JP2’s legacy exists as a form of cultural memory present within social structures, but it is becoming less and less relevant to the personal identity of young people. This study demonstrates the applicability of Hirsch’s concept of post-memory to quantitative analysis of religious heritage in a post-confessional context. Full article

Urban sprawl has been the subject of extensive scholarly investigation, as it is widely regarded as an unfavourable phenomenon with profound socio-economic consequences. Its fundamental forms have been delineated through specific Spatial Form Metrics (SFMs). In southern Poland, there exists a region whose dispersed development pattern is particularly distinctive. Owing to its considerable size—exceeding 5500 km²—it was deemed appropriate to analyse this area using the metrics and categories conventionally applied in urban sprawl research. The findings reveal a settlement pattern often described in the literature as resembling a ‘leopard skin’. Key urban parameters—such as density, intensity, dispersion, and clustering—were most effectively characterised by Shannon entropy levels calculated for these categories. In all instances, the entropy values proved to be very high, indicating minimal variation in development form across the study area. This outcome reflects the prevalence of numerous small, closely spaced building clusters, without the emergence of major concentrations capable of serving as nuclei for service centres with a developed public realm. As a result, structures that would ordinarily provide higher-order services and foster social integration fail to materialise. The implications for the open landscape are pronounced and predominantly negative: both agricultural landscapes and the still-existing, though limited, semi-natural landscapes are severely fragmented by scattered, unstructured building clusters. This fragmentation undermines rational agricultural management and impedes the conservation of self-regenerating areas that approximate the natural landscape. Against this backdrop, the present study examines the built-up structure of Area X in order to delineate pathways for a transition from environmentally detrimental settlement patterns towards forms of development that not only ensure the sustenance of urban life but also align with the broader principles of sustainable urban development, thereby safeguarding the continuity of urban life as a fundamental condition for long-term urban resilience.

This paper presents the results of a study on manners of green area design, with green areas understood as areas with biologically vital surfaces, in the context of contemporary remodelling of historical market squares. This study approaches this problem comprehensively with the example of Lesser Poland—a region in southern Poland. The presented detailed analysis covers cities and towns where a major town or city square was remodelled in the period between 2009 and 2024. The findings of this study of these spaces’ development—both before and after the completion of their respective remodelling projects—have been presented as comparative diagrams. Based on this, essential quantitative parameters linked to green area surface area and the biologically vital area to square ratio were calculated for the pre- and post-remodel stages. Interpreting the findings enabled the identification of the quantitative changes that occurred during the remodelling of each square, and thus outlining of the general tendencies in the design of greenery in these spaces. Research shows that the process of redevelopment of urban markets most often results in a reduction in green space, regardless of its initial condition. In some cases, this phenomenon becomes radical, leading to the almost complete elimination of green spaces from the market square. We compared our findings with those of other studies on the remodelling and redevelopment of the city centres of Polish cities and referred to the literature on diagnosing the phenomenon dubbed as ‘concretosis’ (betonoza in Polish). We also discussed this tendency in the context of the revitalisation of city centres and the programming of functions that city market squares feature after remodelling, as well as the specificities of Polish law in terms of requirements in the planning and design of public spaces. This study’s subject matter also references the general tendencies in planning downtown public spaces that are often historic and which are highly distinct and attractive places in numerous cities and towns around the world.

This study investigates the influence of digital skills, personal innovativeness, and attitudes toward smart home adoption on digital consumer behavior in Poland, as well as the relationship between digital activity and environmental awareness. In the context of growing interest in sustainable development and digital responsibility, the research aims to identify the psychosocial and technological determinants of conscious online behaviors. The study employs a structured survey (n = 1246) using validated scales, which were analyzed through Confirmatory Factor Analysis (CFA) and Structural Equation Modeling (SEM). The findings reveal that personal innovativeness is the strongest predictor of digital consumer behavior, followed by digital skills and, to a lesser extent, smart home adoption. Moreover, digitally active consumers demonstrate significantly higher levels of environmental awareness, suggesting that digital engagement fosters pro-environmental attitudes. Gender differences were observed in the strength of these relationships, with digital skills and innovativeness having a greater impact on women’s behavior, while smart home technology attitudes were more relevant among men. These results contribute to the understanding of digital consumer responsibility and its environmental implications, highlighting the importance of digital competence development and technological openness in promoting sustainable consumption patterns.

The growing global interest in mitigating climate change implies an increased importance of sustainable development to achieve greenhouse gas emission reductions. The paper analyses the impact of key economic and environmental factors, such as the share of renewable energy, gross domestic product (GDP), fossil fuel consumption, final energy consumption in households and industry, and forest area, on greenhouse gas (GHG) emissions in the European Union (consisting of 27 members) and Poland for comparison—for the period from 1990 to 2023. The study fills a gap in identifying the cross-sectoral determinants of greenhouse gas emissions in the EU, focusing specifically on Poland and the whole EU region since the beginning of the European Union. The research involved the implementation of statistical analyses, dynamic analyses, correlation analyses, and regression analyses. The results showed an increase in the share of renewable energy, GDP, and forest area, which was negatively correlated with the volume of GHG emissions. In contrast, final fossil fuel consumption and final energy consumption in industry and households (to a slightly lesser extent) were also significantly but positively correlated. It is worth noting that the strength of calculated relationships differed for the EU and Poland. The study revealed trends and correlations that affect GHG and are relevant to policy implications for EU climate goals. Considering the various determinants of GHG emissions and Poland’s unique situation (high dependence on coal and a large share of heavy industry), conclusions were formulated for Poland’s and the EU’s climate policies in the context of the European Green Deal.

Objective: The aim of the study was to determine the effect a mountain expedition (>3000 m) would have on the physical performance and nutritional indices of alpinists’ health status. Methods: The study included 17 men aged 30.29 ± 5.8 years participating in mountain expeditions to peaks of 5000–8000 m, lasting an average of 34 ± 6 days. The following were assessed: aerobic and anaerobic capacity, body composition and the values of selected biochemical and hematological indices of blood and urine before and after returning from the expeditions and a quantitative analysis of the alpinists’ diet. Results: There was a statistically significant decrease (p ≤ 0.05) in aerobic capacity, anaerobic capacity, subjects’ body mass, muscle mass and the lean body mass of the upper and lower extremities. There was a significant increase (p ≤ 0.05) in erythrocytes, hemoglobin, hematocrit, leukocytes, platelets, neutrophils, monocytes and a significant decrease (p ≤ 0.05) in total and high-density lipoprotein cholesterol, total bilirubin, albumin and total protein. A small percentage of the subjects met the requirements for iron (29.41%), folate (35.29%) and vitamin D (17.65%) supply with diet, as reflected in the blood test results. Conclusions: Despite the observed positive effect of three-week hypoxic exposure on the climbers’ health, the deterioration of aerobic and anaerobic capacity was shown, which, in addition to environmental conditions and systemic inflammation, may have been influenced by adverse changes in body composition. To improve the nutritional status of the body during the expedition and upon return, alpinists should consider including the necessary supplementation of deficient components. Full article

Epipactis helleborine (L.) Crantz is considered a challenging and phenotypically difficult species to identify due to its wide range of morphological variability. This variability is mainly observed in the perianth parts but also extends to the gynostemium structure, which has so far been considered one of the most useful diagnostic characteristics. As a result, a simple graphic illustrating the structural pattern of gynostemium morphology has appeared in 10 different forms in available European taxonomic keys, which significantly complicates the identification of this species. A total of 122 flowers of E. helleborine were collected from four natural populations in the Lower Silesia region (Poland) between 2017 and 2019 and analysed for gynostemium morphological variation. Geometric morphometric analyses, including Procrustes ANOVA, PCA, and CVA, were used to examine gynostemium shape, with statistical tests assessing variation in size and stigma inclination angle among populations, individual plants (ramets), and years of research. Statistical analysis revealed significant positive correlations between gynostemium width and height, with significant variation in size and angle of stigma inclination, primarily driven by population, while ramet and year of research had a lesser impact. Geometric morphometric analyses indicated significant population-level variation in gynostemium shape, with principal component analysis identifying the ventral view as the most informative for discriminating these differences. The first two principal components explained the major shape variation, and canonical variate analysis confirmed that this view is most important for species identification. Full article

The energy industry is constantly changing and evolving. One of the visible solutions is the pursuit of low-emission solutions. One such solution is investment in renewable energy sources (RESs), including hydropower, which in 2023 will constitute a dominant share in the production of electricity from RESs (47.02%) in the world. One of the alternative solutions is the use of hydropower in wastewater treatment plants, whose global potential is estimated at about 4350 TWh. An important issue in the operation of these facilities is their profitability. This article presents an economic analysis of a hydropower plant in the wastewater treatment plant in Toruń (northern Poland) in order to assess its profitability in the context of profits, costs, and payback period. The analyses showed the profitability of 9 out of 12 characterized variants, with the payback period estimated for real variants at 10.75–23.74 years and for theoretical variants at 5.06–5.32 years. The most significant factor in reducing the payback period was the level of electricity production between years, while different types of settlements and changes in electricity sales prices played a lesser role. Taking into account all profitable variants, after 25 years of operation, the net income will amount to PLN 1.07 million for the actual variants and PLN 3.18 million for the theoretical variants. The work can contribute to understanding the specifics of the operation of such facilities, which is consistent with, among others, the goals of sustainable development, climate and energy policies, or the circular economy.

Biomonitoring based on foliage chemistry was used to study the effects of environmental sulfur (S) pollution on forest stands. The foliage samples were collected in two forest ecosystems exposed to industrial emissions: a zinc (Zn) and lead (Pb) smelter plant in Silesia (HCM) and a reclaimed forest on the site of the former borehole S mine Jeziórko (FJSM), in the Tarnobrzeg S deposit region (southern Poland). Scots pine (Pinus sylvestris L.) and silver birch (Betula pendula Roth.) foliage chemistry was analyzed: S (using a TruMac CNS analyzer, Leco Corporation, Saint Joseph, MI, USA), N, P, K Ca, and Mg, and trace elements (Zn, Cd, Pb, Al, Fe, Mn, Cu) using an ICP OES ICAP 6000 spectrometer, Thermo Fisher Scientific, Waltham, MA, USA),. At the HCM site, 20 monitoring points were located in the forest at different directions and at varying distances from the smelter plant. At the FJSM site, 16 sampling points were distributed depending on vegetation type and tree species abudance. The S content in foliage was generally high at both sites. However, at the HCM site, the highest S content was found in areas close to the smelter plant (1664 mg kg⁻¹) and decreased linearly according to the direction of the dominant wind to the east (1098 mg kg⁻¹). S was correlated with Zn, Cd, and Pb (the main elements produced in the smelter plant). At the FJSM site, high S concentrations were observed in degraded soil areas (4816 mg kg⁻¹ in birch, 1563 mg kg⁻¹ in pine). These areas were hot spots that had the highest amount of S in the soil. These results indicate high biosorption of the pollutant by trees. The S concentration was also higher in birch (B) than in pine (P) foliage (regular forest: 1954 mg kg⁻¹ in B, 1272 mg kg⁻¹ in P; degraded area: 4816 mg kg⁻¹ in B, 1563 mg kg⁻¹ in P), and the differences were significant in the degraded areas. At the FJSM site, S was also correlated with Zn and, to a lesser extent, with Cd and Pb. S also influenced nutrient element supply status, in particular Mg. We confirmed that tree foliage chemistry reflects the state of the environment in highly polluted areas, so biomonitoring should be used to assessment of environmental pollution. Full article

Nietzsche is the world’s most (in)famous atheist, bearer of the monumental tiding of the Death of God. His works contain biting critiques of Christianity and, to a lesser degree, of Judaism as well. Rabbi Mordechai Yosef Leiner of Izbica [=RMY] (1800–1854) was a leading Hasidic master in 19th century Poland. Despite their seemingly incongruent world views and backgrounds, bringing the German philosopher and the Polish Rebbe into conversation bears significant fruit. The significance of my study is two-fold. First, based upon similar philosophical moves by both Nietzsche and RMY, I aim to establish a philosophical foundation upon which to create a secular religious space which, beyond the local discussion around Nietzsche and RMY themselves, is of vital importance in a world continuously divided along inter-religious and secular-religious grounds. In addition, I will sharpen what we mean when we discuss the “religiosity” of Nietzsche and how this religiosity may confront nihilism. I believe that Nietzsche’s orienting insight that God is dead can serve as an inspiration to create a phenomenologically religious “space” devoid of metaphysical and transcendental assertions and that there is a Hasidic master willing to meet him there. The quest of RMY was to reveal a Torah bereft of “Levushim”, that is to say, bereft of the familiar Jewish and kabbalistic mythical trappings. When the traditional Christian and Jewish myths which refer to a transcendent reality are discarded, the search for meaning is relocated onto the immanent stage of human (“All too Human”) phenomenology.

Background/Objectives: Nutrition plays a significant role in preventive medicine, as up to 80% of chronic diseases could be avoided by adhering to healthy dietary principles. The aim of our study was to identify dietary habits, awareness, and nutrition knowledge in a random sample of Polish healthcare students and professionals. Methods: Initially, a total screened sample consisted of 1287 respondents, yet the actual response/participation rate was 634/1287. A validated questionnaire for the Polish population, the Dietary Habits and Nutrition Beliefs Questionnaire (KomPAN), was used for the assessment. Results: The majority of respondents were females (84.2% of medical students and 87.2% of healthcare professionals), current non-smokers (79.6% of medical students and 85.2% of healthcare professionals), and had a normal waist circumference (76.3% of medical students and 63.1% of healthcare professionals). Both clinical dieticians and students studying clinical dietetics received significantly different scores of dietary indexes (pro-healthy pHDI-10 and non-healthy nHDI-14) vs. respective groups of respondents. Both healthcare students and professionals who self-reported better nutritional knowledge indeed yielded significantly better results in the dietary indexes as well as nutritional knowledge scores. The nutrition knowledge score was positively correlated with pHDI-10 and negatively correlated with nHDI-14, BMI, age, and waist circumference. Conclusions: Our results illustrate lifestyle trends among Polish healthcare students and professionals, and such results should encourage the development of evidence-based dietary policies targeting healthcare providers. High-quality continuing nutrition education should be obligatorily provided to all healthcare providers to enhance their dietary awareness as well as ensure high quality of care and outcomes achieved by the Polish healthcare system.

The presented paper examines the integration of Artificial Intelligence (AI) in the management of smart cities, focusing on the Silesian and Lesser Poland Voivodships in Poland. This research addresses a notable gap in the analysis of regional AI strategies within urban management, providing a comparative analysis of AI implementation in these two distinct regions. The Silesian Voivodship, with its emphasis on traditional industries such as manufacturing and energy, contrasts with the broader approach of the Lesser Poland Voivodship, which includes applications in life sciences and ICT. The paper explores how AI technologies enhance urban efficiency, sustainability, and livability through practical applications in traffic management, healthcare, energy efficiency, and environmental management. It highlights the importance of a human-centric approach in smart city development, emphasizing inclusivity, transparency, and ethical considerations. The paper also delves into the socio-technical dynamics of AI deployment, illustrating how these technologies can transform urban environments while ensuring that the benefits are equitably distributed and that urban developments are sustainable and resilient. By analyzing specific case studies, the authors aim to provide empirical evidence and insights that contribute to the academic and practical understanding of AI’s role in smart cities, ultimately advocating for the design of AI applications that prioritize human well-being and environmental health.
