61. The effects of the Hand in Hand : empowering teachers(HAND: ET) programme on teacher burnout in Slovenia. Do experience and baseline emotional competencies matter?Ana Kozina, 2024, original scientific article Abstract: As burnout affects teachers’ health and well-being, as well as their teaching understanding interventions beneficial for prevention is crucial. In this study, we explored possible predictors of the decrease in the dimensions of burnout (emotional exhaustion, physical fatigue, cognitive weariness) after the HAND: ET intervention. We used following predictors: teachers’ experience (professional experience and previous experience of activities supporting emotional competencies) and baseline emotional competencies (self-awareness (operationalised as mindfulness), and self-management (operationalised as emotional self-efficacy)). We used data gathered from the Shirom−Melamed Burnout Questionnaire, the Mindful Attention Awareness Scale, the Emotional Self-Efficacy Scale, and a set of demographic questions in a Slovene sample of in-service teachers (N = 185). Teachers’ experiences were not significant predictors of a decrease in any of the dimension of burnout, while baseline emotional competencies, were significant predictors of emotional exhaustion. The findings support the universal nature of the HAND: ET intervention as well as the importance of continuous support for teachers’ emotional competencies.

62. Management measures and trends of biological invasions in Europe : a survey-based assessment of local managersCarla Garcia-Lozano, Josep Pueyo-Ros, Quim Canelles, Guillaume Latombe, Tim Adriaens, Sven Bacher, Ana Cristina Cardoso, Michelle Cleary, Lluís Coromina, Franck Courchamp, Maarten De Groot, 2025, original scientific article Abstract: Biological invasions are a major threat to biodiversity, ecosystem functioning and nature's contributions to people worldwide. However, the effectiveness of invasive alien species (IAS) management measures and the progress toward achieving biodiversity targets remain uncertain due to limited and nonuniform data availability. Management success is usually assessed at a local level and documented in technical reports, often written in languages other than English, which makes such data notoriously difficult to collect at large geographic scales. Here we present the first European assessment of how managers perceive trends in IAS and the effectiveness of management measures to mitigate biological invasions. We developed a structured questionnaire translated into 18 languages and disseminated it to local and regional managers of IAS in Europe. We received responses from 1928 participants from 41 European countries, including 24 European Union (EU) Member States. Our results reveal substantial efforts in IAS monitoring and control, with invasive plants being the primary focus. Yet, there is a general perception of an increase in the numbers, occupied areas, and impacts of IAS across environment and taxonomic groups, particularly plants, over time. This perceived increase is consistent across both EU and non-EU countries, with respondents from EU countries demonstrating more certainty in their responses. Our results also indicate a lack of data on alien vertebrates and invertebrates, reflecting a need for more targeted monitoring and knowledge sharing between managers and policymakers and between countries. Overall, our study suggests that Europe's current strategies are insufficient to substantially reduce IAS by 2030 and hence to meet the Kunming-Montreal Global Biodiversity Framework target.

67. Alkali-activated mineral residues in construction : case studies on bauxite residue and steel slag pavement tilesLubica Kriskova, Vilma Ducman, Mojca Loncnar, Anže Tesovnik, Gorazd Žibret, Dimitra Skentzou, Christos Georgopoulos, 2025, original scientific article Abstract: This research aimed to investigate the potential of using alkali activation technology to valorize steel slag and bauxite residue for the production of high-performance pavement blocks. By utilizing these industrial by-products, the study seeks to reduce their environmental impact and support the development of sustainable construction materials. Lab-scale testing showed that bauxite pavers showed a decrease in mechanical strength with increasing replacement of ordinary Portland cement. Partial replacement up to 20% still exceeded 30 MPa in compressive strength. Steel slag-based pavers achieved the 30 MPa threshold required for the application with selected mix designs. Pilot-scale production-optimized formulations and standards testing, including freeze–thaw resistance, confirmed the technical viability of these products. Life cycle analysis indicated a 25–27% reduction in CO2 emissions for slag-based tiles compared to traditional concrete tiles. Moreover, using industrial residue reduced mineral resource depletion. This study examined the properties of the resulting alkali-activated binders, their ecological benefits, and their performance compared to conventional materials. Through a comprehensive analysis of these applications, our research promotes the circular economy and the advancement of sustainable construction products.

69. First discovery of the North American leaf-mining moth Chrysaster ostensackenella (Lepidoptera: Gracillariidae) in Russia : the genetic diversity of a novel pest in invaded vs. native rangeNatalia I. Kirichenko, Nina A. Kolyada, Stanislav Gomboc, 2023, original scientific article Abstract: Here, we report the first detection of the North American leaf-mining moth Chrysaster ostensackenella (Fitch, 1859) (Lepidoptera: Gracillariidae) on North American black locust Robinia pseudoacacia (Fabaceae) in Primorsky Krai (the Russian Far East) in July 2022. Overall, six moths were reared from the leaf mines and identified based on adult morphology (forewing pattern and male genitalia) and three of them were DNA barcoding. Description of the leaf mines that allowed us to distinguish the damage of Ch. ostensackenella from other gracillariids associated with R. pseudoacacia is provided. The phylogeographic analysis comparing the DNA barcodes from Russia with those from other invaded countries in Europe (Italy) and East Asia (South Korea and Japan) and from the native range (North America) was performed. Intraspecific genetic diversity reached 3.29%. Altogether, 10 haplotypes were revealed among 21 studied specimens in the Holarctic. The detection of one haplotype common for Japan and the USA (North Carolina) suggests that the invasion to East Asia could have happened from the USA directly, rather than through Europe. A shared haplotype defined for Japan and the Russian Far East points at a possible moth species’ spread to Primorsky Krai from earlier invaded Hokkaido. Further distribution of Ch. ostensackenella in East Asia and Europe is expected, bearing in mind the wide planting of R. pseudoacacia in these continents. Furthermore, an accidental introduction of the moth to the Southern Hemisphere, where black locust was introduced, is not ruled out.

70. Invasion genetics of the horse-chestnut leaf miner, Cameraria ohridella (Lepidoptera: Gracillariidae), in European Russia : a case of successful involvement of citizen science in studying an alien insect pestNatalia I. Kirichenko, Natalia N. Karpun, Elena N. Zhuravleva, Elena I. Shoshina, Vasily V. Anikin, Dmitrii L. Musolin, 2023, original scientific article Abstract: Based on the intensive monitoring conducted by our team and volunteers in 2021, the secondary range of an alien horse-chestnut leaf miner, Cameraria ohridella Deschka & Dimić, 1986 (Lepidoptera: Gracillariidae), was specified in European Russia. This invasive pest was confirmed in 24 out of 58 administrative regions of Russia, which it has occupied for approximately 16 years. Analysis of the COI mtDNA gene sequenced in 201 specimens collected in 21 regions of the European part of Russia indicates the occurrence of two haplotypes (A and B), which are also present in the secondary range of C. ohridella in Eastern and Western Europe. The haplotype A dominated and was present in 87.5% of specimens from European Russia. In 2021, C. ohridella produced spectacular outbreaks in Aesculus hippocastanum in southern Russia, where it damaged more than 50% of the leaves in trees in 24 out of 30 distant localities. In the south of the country, the pest infested Acer pseudoplatanus, whereas other species of Acer of European, East Asian, and North American origin showed no signs of attacks. Taking into account that Ae. hippocastanum is present in most regions of European Russia, we expect a further range expansion of C. ohridella up to the Ural Mountains.
