  • Regional species turnover and local host and forest stand characteristics jointly structure early foliar mycobiomes of Scots pine seedlings

    Fems microbiology ecology : 11 (Oxford University Press, 2026)
    The foliar mycobiome plays an important role in tree health and stress resilience, yet factors shaping foliar fungal communities in boreal conifer seedlings remain poorly understood. We investigated how geographic region, seedling origin (planted vs. naturally regenerated), needle nitrogen status, and local stand structure influence needle-associated fungal communities of Scots pine (Pinus sylvestris) seedlings. Needle samples were collected from seedlings without visible disease symptoms across 23 forest stands in southern Finland. Fungal communities were characterized using Illumina ITS2 amplicon sequencing and clustered into operational taxonomical units (OTUs). Alpha diversity was analyzed via linear mixed models (LMMs), and community composition via PERMANOVA and NMDS using Bray–Curtis dissimilarity. Geographic region was the strongest driver of fungal community composition among stands, whereas within stands, community composition was primarily associated with seedling height and birch abundance. Alpha diversity was higher in the Southeastern region compared to the Southwest, and tended to be lower in planted than naturally regenerated seedlings. Moreover, diversity decreased with higher proportions of birch and spruce but increased with higher needle C:N ratios. These findings suggest that early foliar mycobiomes reflect regional conditions and local forest structure, highlighting potential forest management impacts on fungal communities.

  • Genetic insights into drought responses of boreal Scots pine

    Climate change is increasing the frequency and severity of drought in boreal forests, raising concern about the resilience of key tree species such as Scots pine (Pinus sylvestris L.). Understanding tree-level drought responses and their genetic basis is essential for climate-adaptive breeding and management strategies. We assessed drought responses and heritability of drought-response traits in 1,443 Scots pine trees from three progeny trials in southern and central Finland using basal area increment data. Two early-summer droughts in 2019 and 2021 were identified using the Standardized Precipitation–Evapotranspiration Index (SPEI). We quantified resistance, recovery and resilience using a growth-based framework and introduced a novel deviation-from-boundary metric describing departure from the theoretical full resilience in the resistance–recovery plane. Most trees failed to return to pre-drought growth within one year, indicating incomplete short term recovery. Phenotypic correlations between drought-response and growth traits were weak in magnitude (up to 0.24), indicating limited overlap between these trait groups. Genetic-correlation estimates ranged from − 0.72 to 0.63 and were associated with substantial standard errors. Genomic best linear unbiased prediction (GBLUP) models revealed drought response trait heritabilities of 0.03–0.16 in Tuusula and 0.13–0.29 in Hankasalmi. The deviation-from-boundary metric also showed heritable variation, with heritability estimates of 0.03–0.09 in Tuusula and 0.26 in Hankasalmi. Cross-event phenotypic and genetic correlations were weak or imprecise, indicating limited stability across drought events. However, the overlapping 2020 event windows warrant caution. Further validation across independent drought events and sites is needed before these resilience metrics can be considered for operational tree breeding.
  • Deradicalizing transformations: how EU green transition neutralizes degrowth, justice, and decoloniality
    Ramcilovic-Suominen, Sabaheta
    Global sustainability (Cambridge University Press, 2026)
    Non-Technical Summary The European Union presents its green transition (GT) as a transformative response to climate change and environmental crisis. This article examines whether the current policies live up to that promise, and how transformation is interpreted within the European Green Deal and the EU bioeconomy as flagships of the EU's GT. It shows that while climate urgency and public pressure push for transformations, geopolitical competition, and economic growth-first approach pull policy in a different direction. It shows how transformative concepts, including transformations, degrowth, and (decolonial) justice, get systematically co-opted and deradicalized in the process. Technical Summary This article analyzes how socioecological transformations are interpreted and operationalized within EU green policy, focusing on the European Green Deal and the EU bioeconomy. Drawing on qualitative interviews and a policy workshop with European Commission policy officers, it demonstrates that tensions between the EU's green transition and broader transformative agendas originate at the policy design stage rather than implementation alone. Two contradictory motives shape the EU's engagement with transformation narratives: (i) climate urgency and associated social movements, and (ii) EU's ambition to be(come) important global actor in green transition and decarbonization. While the former opens spaces for transformative change, the latter prioritizes competitiveness, growth, and domination. The article advances the concept of deradicalization to explain how transformative agendas – particularly those associated with degrowth and decolonial environmental justice – are selectively translated, depoliticized, or displaced. Structural, political–strategic, corporate, and procedural barriers reinforce this process, stabilizing capitalist agendas and growth-dependent governance under the language of sustainability and green growth. The analysis argues that such deradicalization inhibits movements and initiatives for more justice-centered, decolonial, and post-growth futures, while enabling continuity of socioecological injustices and (neo)colonial relations within EU green politics.
