1. Two new species of Nitocrella (Copepoda, Harpacticoida) from a spring in Loei Province, northeastern ThailandChaichat Boonyanusith, Anton Brancelj, La-orsri Sanoamuang, 2025, izvirni znanstveni članek Povzetek: Two new species of the genus Nitocrella are described from a karstic spring in Loei Province, northeast Thailand. They are the first representatives of the genus Nitocrella Chappuis, 1924, described from Thailand. Nitocrella grandicaudis sp. nov. and N. thailandensis sp. nov. show the peculiar shapes of the inner element of the male P1 basis, the basis of the mandible, and the proximal endite of the maxilla, differing from their congeners. While N. grandicaudis sp. nov. belongs to the chappuisi group according to the absence of a proximal inner seta on the third exopodal segment of the fourth swimming leg, N. thailandensis sp. nov. belongs to the vasconica group because the seta is present on the segment. Despite the low degree of differentiation in morphological characters, the shape of the female caudal ramus and the proximal seta of the male fifth segment of the antennule suggest that N. grandicaudis sp. nov. differs significantly from the other new species in its mating behavior. A detailed description and illustrations of two new species are provided, as well as a discussion on the divergence of both new species. Some comments on the basic understanding of the reproductive behavior of Harpacticoida are included.

2. Polychaetes associated with calcareous red algae Corallina officinalis in the Northern Adriatic SeaValentina Pitacco, Moira Buršić, Ante Žunec, Petra Burić, Neven Iveša, Ines Kovačić, Emina Pustijanac, Ljiljana Iveša, Tanja Vojvoda Zeljko, Borut Mavrič, 2025, izvirni znanstveni članek Povzetek: Polychaetes are important marine invertebrates that contribute to sediment bioturbation, nutrient recycling, and food web dynamics. This study examines the diversity and structure of the polychaete assemblages associated with the red algae Corallina officinalis in areas with different levels of anthropogenic pressures of the Northeastern Adriatic Sea. Sampling was performed in the intertidal zones. Altogether, 54 species from 13 families were found, with Syllidae being the most abundant. Polychaete richness, relative abundance and diversity at sampling locations with and without anthropogenic pressures showed no significant difference. Multivariate analyses revealed significant differences in species composition between sites under anthropogenic pressures and those without, with key species such as Sphaerosyllis pirifera, Syllis rosea, Syllis prolifera, Syllis gerundensis, and Platynereis dumerilii playing significant roles. Syllis rosea was the most abundant in locations without anthropogenic pressures, while S. pirifera was the most abundant in locations under anthropogenic pressures. These results suggest that while polychaete communities are resilient, anthropogenic pressures are causing shifts in species composition. This pattern is consistent with the results of related studies, indicating a broader ecological trend. The shifts observed here should raise concern among conservation ecologists, underscoring the importance of long-term monitoring to understand and mitigate the impacts of human activities on coastal ecosystems.

3. Participatory mapping of the forest community stakeholders in Europe focusing on forest genetic resources, forest reproductive material, and protected forestsTodora Rogelja, Laura Secco, François Lefèvre, Egbert Beuker, Marjana Westergren, Bruno Fady, Santiago C. González-Martínez, Tor Myking, Luc E. Paques, Christian Rellstab, Anže Japelj, 2025, izvirni znanstveni članek Povzetek: The genetic diversity of forest trees, as provided by Forest Genetic Resources (FGR) and being the basis for the production of Forest Reproductive Material (FRM), is fundamental for maintaining forest resilience, adaptability, health, productivity, and biological diversity. Despite their importance, stakeholder governance of genetic diversity remains under-studied. This study aims to address this gap by mapping the forest stakeholder landscape FGR governance. Using the Quadruple Helix Approach, we categorised stakeholders into academia, industry, government, and civil society identifying relevant sub-communities. The mapping process involved iterative revisions through expert consultations, workshops, and literature scoping. Results show that the FGR sub-community is situated between strict conservation efforts and applied forestry, supporting both genetic conservation and productive forest management. The FRM sub-community, dealing specifically with the production and deployment of FRM, prioritises tree breeding, seed production, and afforestation/reforestation programmes. Meanwhile, the Protected Forests (PF) sub-community focuses on strict nature conservation, advocating minimal human intervention while facing pressures from resource extraction, tourism, and land-use conflicts. The diverging attitudes and values of close-to-nature forest management, intensive forestry, and strict protections, respectively, exist within same stakeholder groups, as well as among different ones, and are spanning all sub-communities. The study uncovers key tensions such as competing land-use priorities between forestry, agriculture, infrastructure and energy sectors, limited flow of knowledge between stakeholder categories and governance misalignments between local, national, and international regulations. The findings are particularly relevant for policymakers, forest managers, forest nurseries, conservation organisations, and industry stakeholders to balance conservation with sustainable forest utilisation. By integrating stakeholder perspectives and highlighting key governance challenges, this study shows where a common ground can be found and where divergent opinions are strong, opening the way for more integrated strategies and policies

4. A long-term ecological research data set from the marine genetic monitoring program ARMS-MBON 2018–2020Nauras Daraghmeh, Katrina Exter, Justine Pagnier, Piotr Balazy, Ibon Cancio, Giorgos Chatzigeorgiou, Eva Chatzinikolaou, Maciej Chelchowski, Borut Mavrič, 2025, izvirni znanstveni članek Povzetek: Molecular methods such as DNA/eDNA metabarcoding have emerged as useful tools to document the biodiversity of complex communities over large spatio-temporal scales. We established an international Marine Biodiversity Observation Network (ARMS-MBON) combining standardised sampling using autonomous reef monitoring structures (ARMS) with metabarcoding for genetic monitoring of marine hard-bottom benthic communities. Here, we present the data of our first sampling campaign comprising 56 ARMS units deployed in 2018–2019 and retrieved in 2018–2020 across 15 observatories along the coasts of Europe and adjacent regions. We describe the open-access data set (image, genetic and metadata) and explore the genetic data to show its potential for marine biodiversity monitoring and ecological research. Our analysis shows that ARMS recovered more than 60 eukaryotic phyla capturing diversity of up to ~5500 amplicon sequence variants and ~1800 operational taxonomic units, and up to ~250 and ~50 species per observatory using the cytochrome c oxidase subunit I (COI) and 18S rRNA marker genes, respectively. Further, ARMS detected threatened, vulnerable and non-indigenous species often targeted in biological monitoring. We show that while deployment duration does not drive diversity estimates, sampling effort and sequencing depth across observatories do. We recommend that ARMS should be deployed for at least 3–6 months during the main growth season to use resources as efficiently as possible and that post-sequencing curation is applied to enable statistical comparison of spatio-temporal entities. We suggest that ARMS should be used in biological monitoring programs and long-term ecological research and encourage the adoption of our ARMS-MBON protocols.

9. Planning for renewable energy without conflict : the potential of using sensitivity mapping as a decision-support toolJerneja Penca, Danijel Crnčec, Marko Lovec, 2025, izvirni znanstveni članek Povzetek: Expanding the use of renewable energy is a policy imperative, but it must proceed without compromising other vital objectives – such as biodiversity conservation, water management, cultural heritage, and public health – while also actively involving the public. This study emphasises sensitivity mapping as a decision-support tool for integrating diverse political and societal concerns into renewable energy planning. Unlike prior studies, which focused solely on methodological applications, we highlight the utility of sensitivity mapping as a policy-making instrument. Using Slovenia as a case study, we present an example of comprehensive sensitivity mapping at a national scale involving several protection regimes. The findings demonstrate how sensitivity mapping can identify a greater-than-expected potential for conflict-free renewable energy development. However, the study also exposes that there are limits to expanding renewable energy without encroaching on protection regimes, and raises questions about the feasibility of achieving climate neutrality by 2050 at a country-wide level. As sensitivity mapping gains traction across the EU, we underline its potential to enable anticipatory, integrative, and inclusive planning. We also highlight its role in recognising the limits and trade-offs of energy planning, reinforcing the shift of renewable energy expansion from solely a political decision to one grounded in a broader societal consensus.

10. Pollinators communities differ across years and cropsDanilo Bevk, Janez Prešern, 2021, izvirni znanstveni članek Povzetek: Insect pollination is one of the most important ecosystem services. Pollinator communities are rarely studied across years and crops in the same location. The aim of this study was to investigate the pollinator community structure on five different fruit crops, as well as the activity of different pollinator groups during the day and their temperature preferences. Pollinator activity was observed across two years on apple trees and blueberry, strawberry, blackcurrant and raspberry bushes. Pollinator community structure varied by plant and year. Honeybees were the most numerous pollinators on all plants except blueberry bushes (39-95% of visits). Bumblebee numbers were high on blackcurrant (up to 28%) and blueberry bushes (up to 61%). Solitary bees visited all plants except blueberries. Honeybees, solitary bees, and hoverflies were most active in the middle of the day, while bumblebees became active earlier in the morning and remained active later in the evening. Pollinators also differed greatly in their temperature preferences. This knowledge gained is necessary for less harmful pesticide application management and the development of more sustainable agriculture to maintain pollinator diversity and thus reliable pollination in extreme weather conditions.
