Drained peatlands in northern latitudes have been used for forage production for decades. They are recognized sources of nitrous oxide (N2O) emissions. In boreal regions, grassland renewal is mandatory to maintain high forage productivity and quality, yet renewal practices involving ploughing can significantly increase N2O emissions. Here, we assessed the effect of plough timing (autumn ploughing with spring reseeding (AP) vs summer ploughing with immediate reseeding (SP)) on N2O emissions from a drained peatland in Eastern Finland. We conducted a three-year field experiment measuring N2O fluxes using manual chambers during snow-free seasons and snow gradient method during the snow-covered periods. Results showed that AP (88 kg N2O-N ha−1) emitted 2.6 times more N2O than SP (34.5 kg N2O-N ha−1) over the three years and exhibited greater interannual variability in its N2O emissions. Ploughing in the autumn led to sustained higher N2O emissions for longer periods and affected the following non-growing season and annual emissions considerably. Similarly, three-year yield-scaled N2O emissions were 2.2 times more in AP (3.7 kg N Mg−1) than in SP (1.7 kg N Mg−1). We found that grassland renewal increased the yield compared to the yields prior to renewal. These findings suggest that summer ploughing with prompt reseeding is a more sustainable practice for grassland renewal on drained peatlands, offering reduced N2O emissions without compromising productivity.

This study's aim was to determine the effect of logging residue piles of Scots pine, Norway spruce and silver birch on the base cation concentrations in percolation water below the rooting depth in a clear-cut. The second aim was to determine if the concentrations of nitrate and dissolved organic carbon were related to the concentrations of base cations in percolation water. A Norway-spruce-dominated stand was clear-cut, and logging residues were taken from spruce, pine, and birch trees from the adjacent and similar forest stand to the clear-cut. Piles containing 40 kg m−2 of fresh branches were constructed on the soil surface, covering a 60 cm × 60 cm area, i.e. the whole surface area of the lysimeter that was first installed. A zero-tension lysimeter collected soil percolating water through a logging residue pile and soil profile to a depth of 40 cm below the surface of the ground. Percolation water was collected for chemical analysis at 4–6-week intervals during 2016–2017 and the concentrations of calcium, magnesium and potassium were determined. Logging residues of spruce, pine, and birch caused increased concentrations of base cations in percolation water, and the highest concentrations were associated with birch residues. Dissolved organic carbon concentrations were always low and were not correlated with base cations. Logging residues are located to restrict parts of a clear-cut area in large piles, and this causes elevated concentrations of nitrate below the piles: this study showed that nitrate concentrations were related to the elevated concentrations of base cations.

Native cattle breeds in Europe are vital to agricultural heritage and livestock production, combining adaptation to diverse environments with desirable traits such as high-quality beef and milk. To investigate genetic diversity, local adaptation, and productivity-related characteristics, we generated whole-genome sequences from 289 cattle representing 11 native breeds and the commercial Holstein-Friesian breed across Finland, the Netherlands, and Portugal. These breeds span diverse climates and management systems, from cold northern regions to Mediterranean environments in southern Europe. The dataset comprises over 11 terabytes of paired-end Illumina NovaSeq6000 sequencing data, with an average depth of ~10 × and an alignment rate of ~99.7% against the ARS-UCD1.2 and 2.0 cattle reference genomes. Variant calling identified about 30 million SNPs and 2.7 million small indels distributed unevenly across the genome. Annotation linked many variants to known genes. This genomic resource provides an important foundation for studying genomic diversity, environmental adaptation, small structural variants discovery, and genomic mapping of economically important traits, offering insights for future breeding and conservation programs in European cattle.

We studied commercial fishers’ observations and experience-based knowledge in combination with long-term monitoring data in order to gain a holistic view of the adaptation of fishers to climate change and other drivers on Lake Inari. Fishers’ main sustainability concerns included degradation of the environment, overfishing, and lack of decision-making power. The fishery and fishing have changed due to increased water temperature and lake productivity; the open-water period has become longer and winter fishing season shorter and spring-spawning species, such as pike and perch, have become more common. Fishers’ responses to reduce risks and cope with future uncertainty included both long- and short-term adaptation—achieved through diversification, flexibility, innovation, and mobility. The responses of fishers to multiple changes are variable and based on individual rather than community behavior. We argue that diverse fishing strategies support the adaptation capacity and sustainability of commercial fishing. Sustainable adaptation of commercial inland fisheries could be further enhanced by better monitoring of the hydrology and fishery, by supporting social relations and communication, and through decision-making based on both scientific and fishers’ knowledge.
