    Non-timber forest products (NTFPs), such as berries, mushrooms, chaga, birch sap and spruce sprouts, are widely used for food and nutrition. Their demand is growing in the food, cosmetics, and health sectors at local and international levels. In Finland, most NTFP enterprises are small, family-owned businesses with limited resources. In this, a key issue is to have adequate social networks, about which there is only a little research information available. This study examines the social networks of forest owners producing NTFPs and explores value exchange within these networks. Data was collected through qualitative in-depth interviews with twenty Finnish forest owners. Thematic coding and a social network analysis (SNA) were used to identify key actors, their connections, and value exchange. Findings highlight the significant role of buyers and forest organizations in the forest owners’ networks, while connections to NTFP organizations were rare. Forest owners primarily sought information from forest organizations and research institutions. Additionally, social value and support from different actors played an important role. The results suggest a need for a low-threshold organization to facilitate information sharing and guidance. The study increases the understanding of the heterogenic and multidimensional value networks of NTFPs and makes the development targets in the NTFPs value networks visible.
  • Oak wood megafossils found from Kemiö island in SW Finland

    Memoranda Societatis pro fauna et flora Fennica (Societas pro fauna et flora Fennica, 2026)
    Subfossil tree trunks recovered from the Holocene deposits are commonly used as indicators of past vegetation shifts and climatic fluctuations. Such findings must be scientifically dated prior to any palaeobotanical or palaeoclimatic interpretations. This study concentrates on a subfossil specimen of oak (Quercus sp.) wood unearthed from Kemiönsaari, SW Finland. The specimen available for scientific examination represents a mature tree with > 150 annual rings and stem diameter c. 25 cm. The age of the tree specimen was determined by radiocarbon dating as 3340 ± 28 BP. Radiocarbon calibration results in a calendar year age range between 1732 and 1532 cal BC. The implications of the results are discussed in a multi-disciplinary context. The investigated oak specimen may not be the first one ever discovered in Finland. However, at least to our knowledge, it represents the first piece of evidence of its kind, rigorously dated and described in the scientific literature.

    Drought stress is intensifying globally, but its effects on plant-associated microbiome diversity and stability remain poorly understood. We grew wheat under drought stress and sampled bulk soils, rhizosphere soils and roots across three growth stages to quantify microbial diversity, co-occurrence network stability and the contributions of core taxa to network stability. Drought affected microbial diversity depending on microbial kingdoms, plant niches and growth stages. We further found that drought stress reduced the complexity and stability of microbial networks in the rhizosphere soils while enhancing those in the roots, mainly through shifts in the abundances of core taxa (i.e., taxa that are widely distributed across samples, specific to drought stress and highly connected in the network). Three types of analyses (shared operational taxonomic units, network keystone nodes and taxa with high specificity and occupancy values) were employed to identify the core taxa enriched in the roots under drought stress, including Glycomyces and Thermoactinomycetaceae, which were typical drought-tolerant taxa that are important for maintaining root microbial network stability. Environment stress usually disrupts microbial community stability, but we found drought stress enriched core taxa, enhancing drought-tolerant crop root microbiomes stability. Our findings provide a blueprint for enhancing crop stress tolerance via microbiome manipulation.
