Summary: This study found that the addition of degradable microplastics to farmland soils can increase the decomposition of soil organic carbon, referred to as the "priming effect". The study revealed that the stronger the degradability of the microplastics, the greater the "priming effect" induced. Among the three types of microplastics tested, poly-hydroxyalkanoates (PHA) induced the highest "priming effect". Additionally, the study emphasized the importance of microbial nitrogen mining in driving the "priming effect" due to the nitrogen deficiency of microplastics.

Summary: This study aimed to investigate the effects of long-term nitrogen (N) fertilization on priming effects (PE) induced by labile carbon (C) inputs. It was found that the previously fertilized soil had lower cumulative primed carbon regardless of the mode of glucose addition, and it showed a positive relationship with soil pH and peroxidase activity. The frequency of glucose addition affected the intensity and regulation of soil PE.

Summary: The study shows that the functioning of soil microorganisms strongly depends on soil nutrient concentrations in the forest sites studied. In nutrient-poor sites, soil microorganisms were more stressed in pure and mixed coniferous forests, especially in Douglas-fir. In contrast, microbial structure and functional indicators in beech forests varied little with site conditions, likely due to ample root-derived resources provided by beech.

Summary: This study found that tundra vegetation types and their carbon supply to rhizosphere microbes determine soil organic matter cycling independent of temperature. The primary productivity of tundra plants at low elevation and under ambient light supported higher microbial biomass and nitrogen immobilization, but lower microbial enzymatic activity and soil organic matter humification. These results highlight the importance of tundra plant community characteristics for soil microbial community and soil organic matter turnover.

Summary: This study assessed the effects of recurrent drought on the growth and water relations of European larch and Norway spruce. The results showed that Norway spruce had stronger responses to recurrent drought, with increased water-use efficiency, while European larch was less affected in terms of xylogenesis. This suggests that increasing drought frequency in the future could have significant impacts on the carbon and water dynamics of these tree species.

Summary: European mountain grasslands are increasingly affected by land-use changes and climate, which have significant impacts on the partitioning of carbon and nitrogen pools amongst different grassland compartments. Reduction of management intensity and abandonment of hay meadows and pastures result in increased above-ground phytomass, root mass, and litter, while decreasing the contribution of topsoil to the total organic carbon pool. Climate influences the effects of land use on carbon and nitrogen pools mainly through mean annual temperature.

Summary: Warming in mountain regions is projected to occur three times faster than the global average. Observational studies have shown species loss and colonization by novel species in mountain plant communities due to climatic change. This study monitored translocated mountain plant communities and found increasing species turnover and colonization by novel species under two future climate scenarios. The colonization of novel species is facilitated by direct environmental filtering, which is affected by interacting climate stressors. The study provides experimental evidence of local species loss in mountain plant communities and reveals abrupt threshold dynamics.

Summary: Soils play a crucial role in ecosystem functioning and service provisioning. Plant diversity has positive effects on soil organic matter, but most studies have focused on topsoil and long-term studies are limited. This study investigated the impacts of plant diversity on soil carbon and nitrogen concentrations and stocks, and found that higher plant diversity increased carbon and nitrogen storage, particularly in the topsoil. The effects of plant diversity on soil organic matter became stronger over time and extended to subsoil layers.

Summary: Grasslands face increasing drought intensity, but their response to it is unclear. This study investigated the effects of drought intensity on plant productivity, plant-soil carbon and nitrogen cycling. The results showed that slow-strategy plant communities were more drought resistant and had higher productivity thresholds compared to fast-strategy communities. Increasing past drought intensity resulted in greater microbial uptake of recent plant-assimilated carbon and increased soil nitrogen availability. The recovery responses of plant communities varied depending on their strategies, with the fast-strategy community exhibiting greater compensatory growth and the slow community allocating more carbon to microbial biomass.

Summary: Climate warming in high latitude grasslands may cause significant carbon losses from soil. The effects of warming and nitrogen availability on belowground carbon dynamics and the fate of recently photosynthesized carbon are not well understood. In an Icelandic study, soil warming increased ecosystem respiration and resulted in net CO2 emissions. Surprisingly, plants in warmed soil were nitrogen limited, reducing primary productivity and decreasing recently assimilated carbon. Microbes in the soil became increasingly carbon limited under warming and had increased microbial uptake of recent carbon. The findings suggest that warming induced nitrogen and carbon limitations, reducing CO2 uptake and accelerating the release of photosynthesized carbon, thereby decreasing carbon sequestration potential in grasslands. The study highlights the importance of belowground carbon allocation and carbon-nitrogen interactions in subarctic ecosystems in a warmer world.

Summary: Warming in mountain regions is projected to be three times faster than the global average. Pronounced climate change will likely lead to species reshuffling in mountain plant communities and consequently change ecosystem resilience and functioning. Yet, little is known about the role of inter- versus intraspecific changes of plant traits and their consequences for functional richness and evenness of mountain plant communities under climate change.

Summary: Targeted removal experiments are powerful tools for assessing the effects of plant species or functional groups on ecosystem functions. However, removing plant biomass can introduce biases in the observed responses. We propose using a gradient of biomass removal controls to account for these biases and demonstrate the relevance and advantages of this design through conceptual examples and data analysis.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.
