Research in social work (Bristol University Press, 2025)
This chapter looks at nature-based interventions (NBIs) as an ecosocial method within social work to address complex challenges faced by individuals in precarious situations. Through case studies from Ireland, Finland and Italy, it examines how NBIs – including equine-assisted services, outdoor youth activation workshops and green care services – promote social inclusion, mental wellbeing and community cohesion. The findings from the case studies demonstrate the benefits of integrating nature into social work practice, highlighting improvements in health and wellbeing, learning, self-determination and social relationships. The chapter also critically reflects on the limitations of NBIs, including methodological challenges and concerns about their structural impact. Ultimately, it argues that NBIs offer a promising approach to holistic wellbeing and sustainability within social work, advocating for their ethical and context-specific application in future social work practice, education and research.

Reproduction : 6 (Bioscientifica, 2025)
Spermatogenesis culminates in a dramatic morphological transformation, including a tight compaction of the chromatin and nuclear reshaping that largely silences transcription. Due to transcriptional silencing, the production of sperm-specific proteins needed for the morphological transformation requires active storage and translational regulation of mRNAs transcribed in earlier cell types. The germline-specific ribonucleoprotein (RNP) granule, the chromatoid body (CB), accumulates RNAs and has a role in RNA regulation in early haploid cells (round spermatids). In late haploid cells (elongating spermatids), the CB is transformed into the so-called late-CB, whose function in RNA regulation has remained elusive. Here we characterized the function of the late-CB by identifying proteins and RNAs interacting with the known late-CB marker, testis-specific serine/threonine-protein kinase 2 (TSSK2). We showed that TSSK2 and the late-CB associate with translation initiation factors and ribosomal proteins. Furthermore, we revealed an association of TSSK2 with a specific set of mRNAs that are enriched in polysome fractions in elongating spermatids, supporting the role of the late-CB in temporally regulated translation. These results link the function of the late-CB to RNA regulation during late spermatogenesis for the first time, providing important novel information about the RNA regulatory processes required for spermatogenesis and male fertility.

Forest ecology and management (Elsevier, 2025)
Selection harvesting in fertile, drained peatlands is an alternative for even-aged forestry, where clearcutting takes place at the end of each rotation period. Avoiding clear-cuts has been promoted due to reducing negative externalities, like nutrient loading to waterways and significant greenhouse gas emissions after harvesting. Our aim was to understand the responses of suppressed Norway spruce trees to selection harvesting. We analysed biomass accumulation and priorities of carbon allocation to stems, proximal roots and distal roots. We quantified carbon isotope composition (δ13C) and cross-sectional growth of proximal (supporting) roots and distal (water and nutrient transportation) roots. The study took place in a drained, fertile boreal peatland site in southern Finland, where a selection harvest was conducted in 2016, while an area as a control was left untouched. Our results show that suppressed Norway spruce trees increased their cross-sectional growth of proximal roots and distal roots twice as much as that of the stem during the first five years after the selection harvest. The timing and magnitude of carbon allocation to proximal roots and distal roots were immediate and equal, underlining the fact that trees were investing in mechanical support and nutrient and water uptake. These results show that the climate benefits of selection harvest were not delayed. Instead of immediate growth of stems, we found immediate growth of roots.
