3. Overcoming biases in opportunistic citizen science for studying life history traits of an invasive leaf-mining tree insect pestNatalia I. Kirichenko, Maria A. Ryazanova, Oksana V. Kosheleva, Stanislav Gomboc, Barbara Piškur, Maarten De Groot, 2025, izvirni znanstveni članek Povzetek: The aim of this study was to determine whether opportunistic citizen science can support the detection of life history traits in invasive insects. Using the invasive leaf-mining micromoth Macrosaccus robiniella (Clemens 1859) (Lepidoptera: Gracillariidae) as a model species, we analyzed data from iNaturalist submitted by citizen scientists to assess the variability in its leaf mines on its native host, Robinia pseudoacacia L., 1753 (Fabaceae), across both the moth’s invaded (Europe, North America–Eastern United States) and native range (North America–Southern and Western Unites States, Eastern Canada). We examined 86,489 photographs collected over the past 20 years to compare the occurrence and proportions of different M. robiniella leaf mine types between invaded and native ranges using three search variants: (I) M. robiniella, (II) all endophagous invasive insects associated with R. pseudoacacia, and (III) the host plant itself. The first two datasets revealed differences in the ratio of leaf mine types between Europe and North America (when analyzed separately for native and invaded areas), whereas the third dataset showed no significant differences in either the presence or proportion of mine types between invaded and native ranges. Leaf mine types atypical of M. robiniella, which resemble damage caused by other invasive insects such as Parectopa robiniella Clemens, 1863 (Lepidoptera: Gracillariidae) and Obolodiplosis robiniae (Haldeman, 1847) (Diptera: Cecidomyiidae)—also associated with R. pseudoacacia—have been observed in Europe for at least a decade. Our main conclusion is that, when investigating the life history traits of invasive herbivorous insects, focusing data collection on the host plant rather than on the insect species alone can reduce biases associated with opportunistic citizen science and help reveal true ecological patterns.

4. Temperature-driven shifts in spatiotemporal stability of climate-growth responses of Douglas-fir (Pseudotsuga menziesii) from the southern Baltic Sea regionMarcin Miroslav Klisz, Radosław Puchałka, Mariusz Gławenda, M. Koprowski, Roberts Matisons, Sandra Metslaid, Aleksei Potapov, Tobias Scharnweber, Eric Andreas Thurm, Rita Verbylaite, Adomas Vitas, Martin Wilmking, Jernej Jevšenak, 2025, izvirni znanstveni članek Povzetek: The southern Baltic region spans a significant part of the European continent with its forests under significant pressure due to climate changes. The implications of these changes are crucial for both native and non-native tree species. Under future climate scenarios, most native conifer populations might lose their climatic optima in the region. In contrast, for non-native Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), climatic conditions are expected to become optimal in the Baltic Sea region. Therefore, understanding the acclimatisation trajectory of Douglas-fir over the last century is essential to assess its potential to supplement retreating species and reduce pressure on local habitats. To study the region-wide acclimatisation in the secondary distribution, we established a network of 27 Douglas-fir tree-ring chronologies along the south Baltic Sea. We determined the spatio-temporal stability of the climate signal in tree rings and the potential coastal effect on the plasticity of the growth response. We found a region-wide trend of climate-growth relationships, with a dominant effect of the early-growth season temperatures being more pronounced for mature than young stands. Sites with higher mean annual temperatures exhibit a stronger positive temperature–growth correlation, demonstrating the sensitivity of Douglas-fir to climate warming. Douglas-fir could serve as a more heat-tolerant alternative to the declining European species of the Pinaceae family and contribute to the preservation of functionally comparable coniferous forest communities. However, forest practitioners should be aware that Douglas-fir may alter habitat conditions affecting microclimate and influencing species diversity.

5. Leaf mine types and associated parasitism in the invasive tree insect pest Macrosaccus Robiniella (Lepidoptera: Gracillariidae) : a case study from slovenia and croatiaNatalia I. Kirichenko, Stanislav Gomboc, Oksana V. Kosheleva, Dinka Matošević, Barbara Piškur, Maarten De Groot, 2025, izvirni znanstveni članek Povzetek: Since its first documentation on the European continent in 1983, the invasive micromoth Macrosaccus robiniella (Clemens, 1859) (Lepidoptera: Gracillariidae) was known only for its lower-side blotch mines occupying one of the leaflet halves (common mine type, hereafter mine type 1). In 2023, in abundant populations of M. robiniella in forest areas of Slovenia and Croatia (with more than 50% of leaves damaged), we observed that, in addition to the common mine, this invasive species is capable of forming three other mine types. One (type 2) resembles the common mine type by occupying one half of a leaflet, but the mine is situated on the upper side of the leaf. The two other mine types differ from the common mine in both appearance and position on the leaflet. These include a blotch above the midrib on the upper side of the leaflet (type 3) and a narrow blotch at the edge, causing strong downward folding (type 4). The mines of types 3 and 4 resemble the damage caused by two North American black locust herbivores that are also invasive to Europe: the gracillariid Parectopa robiniella Clemens, 1863 (Lepidoptera: Gracillariidae) and the gall midge Obolodiplosis robiniae (Haldeman, 1847) (Diptera: Cecidomyiidae), respectively. In the studied localities, the relative abundance of mine types 3 and 4 was about four times higher than that of mine type 1. The parasitism rate in these mines was 6.5 times lower compared to that in mine type 1. No statistical difference was found in the parasitism rate between mine types 3 and 4. We discuss how the leaf-mining behaviour of M. robiniella may provide an enemy-free space, conferring a survival advantage and supporting a high population density in forested areas.

6. Sustained circulation of enterovirus D68 in Europe in 2023 and the continued evolution of enterovirus D68 B3-lineages associated with distinct amino acid substitutions in VP1 proteinAurora Hirvonen, Caroline K. Johannesen, Peter Simmonds, Thea K Fischer, Kimberley Benschop, 2025, izvirni znanstveni članek Povzetek: Background Enterovirus D68 (EV-D68) causes respiratory disease ranging from mild to severe and in rare cases a paralytic syndrome, called acute flaccid myelitis (AFM). Since the global EV-D68 outbreak in 2014, the virus has mainly circulated in biennial epidemic cycles with peaks detected during even years. However, following the COVID-19 pandemic, the seasonal pattern of EV-D68 has been characterized by large yearly upsurges. Here, we describe the circulation of EV-D68 in Europe in 2023 and track its genetic evolution. Study design Data was compiled from members of the European Non-Polio Network (ENPEN). This included monthly data on the total number of EV samples tested, EV positive samples, EV-D68 positive samples and cases, and other EV positive samples detected in 2023. Information on sample types and surveillance system was recorded. Sequence data from the VP1 gene was used for phylogenetic and amino acid sequence analysis. Results EV was detected in 13,585 out of 203,622 diagnostic samples tested (6.7 %), of which 402 (3.0 %) were determined as EV-D68, representing 386 cases. EV-D68 infections peaked in October 2023 (136/386; 35.2 %). 267/386 (69.2 %) of EV-D68 cases were captured through clinical EV surveillance, almost all of which (202/204 of positive samples with sample type information) were detected in respiratory specimens. Phylogenetic analysis performed on 99 VP1 sequences revealed a distinct B3-derived lineage with a previously undescribed residue change, D554E, in Europe. Conclusions The study documents sustained circulation of EV-D68 in Europe in 2023, the evolution of B3-derived lineages, and appearance of previously undescribed amino acid substitutions in Europe. This stresses the need for continuous EV-D68 surveillance and harmonization of EV-D68 detection practices towards better data comparability across countries.

7. Epidemiological and clinical insights into enterovirus circulation in Europe, 2018 - 2023 : a multi-center retrospective surveillance studySten de Schrijver, Emiel Vanhulle, Anne Ingenbleek, Leonidas Alexakis, 2025, izvirni znanstveni članek Povzetek: Background Enteroviruses (EV) cause yearly outbreaks with severe infections, particularly in young children. This study investigates EV circulation, age, and clinical presentations in Europe from 2018 to 2023. Methods Aggregated data were requested from the European Centre for Disease Prevention and Control National Focal Points for Surveillance and European Non-Polio Enterovirus Network. Data included detection month, specimen type, age group, and clinical presentation for the 10 most commonly reported EV types per year. Results Twenty-eight institutions (16 countries) reported 563 654 EV tests during the study period with 33 265 (5.9%) EV positive. Forty-two types were identified (n = 11 605 cases) with echovirus 30 (E30), coxsackievirus A6 (CVA6), EV-D68, E9, E11, CVB5, E18, CVB4, EV-A71, and E6 most frequently reported. E30 declined after 2018/2019, while CVA6, CVB5, E9, E11, and EV-D68 were prevalent both before and after the coronavirus disease 2019 (COVID-19) pandemic, and CVB4 and E18 were prevalent after the pandemic. A shift in seasons (summer to fall) and specimen positivity (feces to respiratory) was observed. Neurological signs predominated among EV-A71, CVB4, CVB5, E6, E9, E11, E18, and E30 (30%–72%). CVB4, CVB5, E9, E11, and E18 were frequently reported among neonates (18%–32%). CVA6 was frequently associated with hand, foot and mouth disease, and EV-D68 with respiratory infections. Paralysis was reported among 22 infections, associated with 10 nonpolio types. Conclusions This study emphasizes the widespread circulation and severity of EV infections in Europe, as well as the (re)emergence of specific types postpandemic. Our findings highlight the need for continuous EV surveillance to monitor variation in circulation, age, and clinical presentations, including paralysis among nonpolio EV infections.
