    Ash fertilization is a forest management practice used to improve forest growth in boreal peatland forests. It impacts soil chemistry, vegetation, and soil organisms, yet little is known about its long-term impacts on soil microbial communities. Here, we focus on the long-term impacts of ash fertilization on the soil microbiome of drained boreal peatland forests in Finland. We hypothesized that the ash-induced changes in soil chemistry have led to long-term changes in soil microbial communities. To study this, we analyzed soil bacterial and archaeal communities from seven drained peatland forest sites in Finland. Each site had an ash fertilized plot (fertilized 8−43 years before sampling) and an unfertilized plot. Soil pH was higher at ash fertilized plots in five out of the seven sites. Pseudomonadota, Bryobacteraceae, and Planctomycetaceae were more abundant in samples from the control plots, whereas Actinomycetota were more abundant in samples from the ash fertilized plots. According to distance-based redundancy analysis, soil pH was important driver of soil bacterial and archaeal community structure. Site explained a greater proportion of community variation than treatment. Therefore, impacts of wood ash on soil in peatland forest stands should be considered by taking into account their site-specific factors and management history.

    Recognizing the critical role of healthy soils in global food security, this large-scale study evaluated the physicochemical properties of 188 wheat soils across nine European pedoclimatic zones and assessed the influence of climate and farming system. Soils exhibited substantial variability in bulk density (0.7–1.7 g cm−3), pHH2O (5.0–9.1), effective cation exchange capacity (4.5–42.0 cmolc kg−1), base saturation (14%-100%), organic matter (1.6%-19.1%), and total inorganic carbon (0.7–106.3 g kg−1). Redundancy Analysis (RDA) showed that climatic and geographic factors were more strongly associated with soil properties than farming system, whose effects were significant but smaller and context-dependent. Mean annual temperature and precipitation were associated with soil pH, base saturation, organic matter, and inorganic carbon, and indirectly influenced bulk density and eCEC. Soil properties were primarily structured by climatic gradients, reinforcing climate as a dominant soil-forming factor. Farming system effects were detectable but variable across pedoclimatic zones, indicating that management can locally modulate specific soil properties, although with lower explanatory power than climate. Based on these spatial associations and literature projections, warming trends may contribute to increased organic matter decomposition, higher bulk density, and reduced nutrient retention. Mediterranean regions appear particularly vulnerable due to declining precipitation, potentially linked to alkalinization and salinization. Although organic farming can locally enhance organic matter, reduce bulk density, and maintain inorganic carbon stocks, its effects are secondary to climate at the continental scale. These findings, based on spatial rather than temporal relationships, support region-specific soil management strategies integrating climate adaptation to sustain soil quality, productivity, and ecosystem services.

    Progress in organic coatings (Elsevier, 2027)
    The growing demand for sustainable textile manufacturing has intensified the search for renewable alternatives to petroleum-based dyes and binders used in textile printing. However, the industrial adoption of natural dyes remains limited by poor dye fixation, inadequate durability, and the lack of bio-based binder systems capable of delivering high printing performance. In this study, a bio-based, water-borne printing paste was developed by combining a chitosan–cationic starch binder with a natural dye extracted from sea buckthorn pomace, an agricultural by-product, for screen printing of cellulosic textiles. The formulation was optimized using zeta potential, quartz crystal microbalance with dissipation (QCM-D), and rheological analyses to understand dye–binder interactions and establish suitable printing conditions. At 3% dye concentration, the biobased paste produced uniform prints with approximately twice the color strength of the commercial polyurethane-based binder (K/S = 3.07 vs. 1.53). The printed textiles also demonstrated good wash, rub, and perspiration fastness, with tactile comfort comparable to that of the commercial system. In addition, the bio-based formulation exhibited antimicrobial activity against Escherichia coli and Staphylococcus aureus, which was retained in the printed textiles after washing. The sea buckthorn dye showed no skin-sensitizing potential under the tested conditions, while cytotoxicity and oxidative stress were observed only at high concentrations. Overall, this study demonstrates that agricultural waste-derived natural dyes, combined with a biobased binder, can produce durable, multifunctional, and skin-compatible printed textiles, offering a promising platform for biobased textile printing systems with natural dyes.

    The Baltic Sea region is impacted by pollution, noise, offshore construction, shipping, fisheries, eutrophication and climate change. Seals are important top predators here, but little is known about their at-sea distribution. Using satellite telemetry data from 90 harbour seals Phoca vitulina and 65 grey seals Halichoerus grypus together with haulout counts, we modelled habitat suitability and relative population densities across the region. We used generalized additive mixed models (GAMMs), incorporating a range of static and dynamic environmental variables. Habitat suitability of both species was positively related to proximity to haulouts, explaining 25-30% of the total deviance. Other important variables, explaining 2.5-6% of the deviance in habitat suitability, were increased wave exposure and colder sea surface temperature for harbour seals and wave exposure and higher sea bottom oxygen saturation for grey seals. Harbour seals showed a preference for more coastal habitats than grey seals. The analyses revealed an imbalance between habitat suitability and actual distribution, particularly for grey seals, where some areas with high suitability had low seal densities. This likely reflects the dramatic population fluctuations of seals in the area over recent centuries related to hunting and pollution. Overlap of suitable habitats between the species in the southern and western Baltic indicates interspecific competition that will likely increase as grey seals recolonise their previous range. Our study constitutes the first comprehensive analysis of seal distribution in the Baltic area and is a valuable tool for managers and ecologists assessing pressures and ecosystem interactions in an area where anthropogenic activities are increasing.
