  • Intentional release of tropical aquarium fishes? Orange chromide (Pseudetroplus maculatus) found in Finland
    Granroth, Janne; Pihlström, Henry; Kuningas, Sanna
    Memoranda Societatis pro fauna et flora Fennica (Societas pro fauna et flora Fennica, 2026)
    Ornamental fish keeping is a popular hobby around the world, including Finland. Occasionally, aquarium fish end up in the wild either accidentally or via intentional release. Most such escapees undoubtedly perish quickly, but some may survive long enough to have a negative impact on the native fauna. Impacts of alien species on native fish may include predation, competition, hybridization, and the spread of diseases. These effects are especially noticeable if the alien species manage to form self-sustaining populations. While anecdotal reports of exotic aquarium fish encountered in the wild have been published from Finland and other European countries, the true scale of this phenomenon is difficult to establish. Here, we report the discovery of two individuals of the South Asia-native orange chromide (Pseudetroplus maculatus, Cichlidae, Cichliformes) that were discovered freshly dead on a riverbank in southern Finland. We discuss the possible biological risks associated with the release of exotic aquarium fishes in a Finnish context.
  • The Energy Transition Shaping the World Order: Russia and Finland’s Geopolitical Positioning
    Mikkola, Olli-Matti; Liuhto, Kari (toim.); Sipilä, Joonas (toim.)
    Inevitable Instability in Russia (Palgrave Macmillan, 2026)
    The aim of this article is to examine Finland’s geopolitical positioning in the context of the energy transition and Russia’s view of the world order, which will be shaped by the energy transition from fossil fuels to cleaner and renewable energy. Russia continues to promote the concept of multipolarity as a means of misleading the international community from its ambitions in regions it perceives to be within its sphere of interest. To ensure the protection of the sovereignty of smaller states, it is essential to understand the motivation behind the Russian perception of the global order. Finland is proactively engaged in the development of renewable energy production and has identified opportunities in the domain of hydrogen and emerging technologies. The strategic importance of this issue is evident, and a definitive policy could result in Finland becoming an energy exporter. This development should also be considered as an act for Finland to gain geopolitical power. The enhanced connectivity of Finland within the European renewable energy market fosters a greater degree of autonomy from Russia. As a neighbouring state to Russia, Finland’s energy system, based on renewables, must be resistant to war. This approach is applicable throughout Europe.
  • Breeding for multi‐stress resilience in crops: Myth or possibility?
    Khazaei, Hamid; Dodd, Ian C.; Ortiz, Rodomiro
    Plants, people, planet (John Wiley & Sons, 2026)
    Climate change is increasing the frequency and intensity of combined abiotic and biotic stressors that may occur simultaneously or sequentially, dramatically reducing crop growth and yield stability. Plant breeding activities primarily target crop improvement for a single stressor, limiting crop resilience under complex environmental conditions. This opinion paper highlights the complexity of crop breeding for multi-stress growing conditions and discusses major challenges and opportunities to enable plant breeders to develop more climate-resilient crops. It also outlines the importance of integrating conventional breeding approaches with multi-omics and novel breeding technologies to develop multi-stress resilient crop cultivars. Identifying and validating key regulatory genes involved in multi-stress resilience and evaluating their performance across diverse genetic backgrounds, environments, and stress combination scenarios are needed. Although achieving complete multi-stress resilience remains an immense challenge, advances in integrative approaches and cross-disciplinary collaboration are steadily improving the potential to enhance crop resilience to multiple environmental stresses.
  • Mittaristo nautojen hyvinvoinnin arviointiin lypsykarjoissa. 2. painos
    Frondelius, Lilli; Mughal, Mikaela; Koistinen, Tarja; Sarjokari, Kristiina; Tuomisto, Leena
    Luonnonvara- ja biotalouden tutkimus : 22/2026 (Luonnonvarakeskus, 2026)
    Raportti korvaa aiemmin ilmestyneen julkaisun Luonnonvara- ja biotalouden tutkimus 17/2026. Tässä raportissa esitetään kehittämämme lypsykarjojen hyvinvoinnin arvioinnin mittaristo sekä ohjeet arvioinnin toteuttamiseksi. Hyvinvoinnin arviointi kattaa kaikki lypsykarjan eläinryhmät – juottovasikat, nuorkarjan ja lehmät. Menetelmä sisältää mittauksia tilalla, kysymyksiä tuottajalle ja tietokannoista poimittavia tietoja. Käytettävät hyvinvoinnin mittarit ovat eläin-, resurssi- tai toimintatapaperusteisia. Mittaristo sisältää 44 hyvinvoinnin indikaattoria, joista juottovasikoilla mitataan 33:a, nuorkarjalla 24:ää ja lehmillä 34:ää. Hyvinvoinnin arviointimenetelmän avulla voidaan tuottaa tietoa sekä eläinten hyvinvoinnin edistämiseksi tilatasolla että mahdollistaa hyvinvointitiedon välittäminen koko elintarvikeketjussa. Tavoitteena on tarjota luotettavaa ja vertailukelpoista tietoa, jota sidosryhmät voivat hyödyntää kehittämistyössään ja viestinnässään.
  • Exploring new cellular agriculture-based value chains via an analysis on potential feedstock sources in Finland
    Niemi, Jarkko K.; Nappa, Marja; Ritala, Anneli; Nordlund, Emilia
    Future foods (Elsevier, 2026)
    The aim of this study was to examine cellular agriculture-based value chains in Finland with two specific objectives: 1) to estimate the potential of selected Finnish agri-food industry side streams and agri-biomasses as the source of carbon for microbial protein production and 2) to identify the barriers and enabling factors related to four cellular agriculture-based value chains based on the Finnish feedstocks sources for fermentation. By evaluating the carbohydrate content of 13 plant-based biomass streams (molasses, brewers spent grain, distillers spent grain, sugar beet stalk, sugar beet pulp, oat husk, wheat bran, rapeseed cake, potato cell juice, potato peels and residues, potato tops, straw, surplus grass) as a sugar source for fermentation, the total microbial protein production potential was calculated annually at ca. 290 000 and 360 000 tons for precision and biomass fermentation, respectively. Among the agricultural and food industry streams, straw and oat husk biomass could theoretically supply feedstock for 211 000 and 22 000 tons of protein per year by biomass fermentation, respectively. This is a substantial amount, e.g. when considering 120 000 tons of protein needed annual by Finnish population. The qualitative part of the study elaborated barriers and opportunities of the biotechnology-based production processes using four value chain concepts with distinct feedstock source (grass, bran/husk, sawdust and greenhouse residues) as case examples. The qualitative analysis concluded that, in addition to bioprocess development for reducing production costs, key factors for ensuring well-functioning cellular agriculture business models include resolving agricultural feedstock pre-processing and logistics, optimized facility location, and access to renewable energy.
