Abstract Aims. Forests across the world are subject to disturbance via wind, wildfire, and pest disease outbreaks. Yet we still have an incomplete understanding of how these stressors impact forest biota - particularly soil microbes, which govern carbon nutrient cycling. Methods. Here, investigated windstorms on bacterial communities in Kielder Forest, a temperate coniferous north England. Within ten individual sites, defined by common stand composition topography, established 50 m2 plots undisturbed stands, nearby stands that were moderately and/or severely disturbed windthrow. Soils sampled within each 22 study plots, analysed for changes nitrogen content, pH, root biomass, community structure. We separately sequenced bacteria from bulk soils, rhizosphere tissues assess whether impacts varied based proximity microbiota tree roots. Results. Less than year after storm, found most had lower canopy cover, higher smaller fine biomass stands. Disturbance also impacted beta-diversity, but effects subtle did not vary among assemblages vs. soils. Conclusions. Impacts aboveground biogeochemistry can be significant, relatively well-buffered against changes. However, altered patterns growth cycling may longer-term implications recovery windthrow disturbances.

Abstract Canopy openings are increasing in Europe’s forests, yet the contributions of anthropogenic and ecological agents disturbance to this increase remain debated. Here we attribute root cause all stand-replacing canopy disturbances identified for Europe period 1986–2020 from Landsat data (417,000 km²), distinguishing between planned unplanned (i.e., by human land use versus wind, bark beetles, wildfire). We show that humans dominate European forest regime, accounting 82% area disturbed. Both increased early 21st century (+24% +30% relative late 20th century). Their changes linked, with simultaneous increases on 68% area. conclude an important direction tackling change policy management is break link forests.

Forest disturbances are increasing around the globe due to changes in climate and management, deteriorating forests' carbon sink strength. Estimates of global forest budgets account for losses plant biomass but often neglect effects on soil organic (SOC).

Soil fungi belonging to different functional guilds, such as saprotrophs, pathogens, and mycorrhizal symbionts, play key roles in forest ecosystems. To date, no study has compared the actual gene expression of these guilds soils. We used metatranscriptomics competition for organic resources by fungal groups boreal, temperate, Mediterranean Using a dedicated mRNA annotation pipeline combined with JGI MycoCosm database, we transcripts three targeting enzymes involved C- N mobilization from plant microbial cell walls. Genes encoding degradation walls were expressed at higher level saprotrophic than ectomycorrhizal pathogenic fungi. However, showed similarly high levels genes wall degradation. Transcripts N-related transporters more highly other groups. that compete soil matter, suggesting their interactions could decelerate C cycling.

The construction of sports spaces such as ski resorts leads to deforestation, soil degradation and carbon (C) loss. However, the impact pistes on C nutrients remains unclear. an 18-year-old piste operation stock stoichiometry C, nitrogen (N), phosphorus (P), bulk density, water content across a 0–100 cm profile in forest area Northeast China was quantitatively assessed using equivalent mass method fixed depth method. overestimated N P stocks SP by 5% 8% relative used reference. demonstrated that N, were significantly reduced 27.4%, 21.3%, 27.5%, respectively, comparison undisturbed forest.

Natural disturbances play an important role in shaping the dynamics of mountain forests, yet their effects on essential ecosystem services, such as protection against natural hazards, can be significant. With challenges posed by climate change and increasing disturbances, well complexities salvage logging, there is a growing interest understanding post-disturbance development unsalvaged alongside advancement decision support systems aimed at ensuring sustained provision services. In this study, we combined space-for-time substitution approach with long-term monitoring data to evaluate regeneration processes deadwood decay following three distinct windthrow events Central European forests that were locally (specifically Vaia 2018, Kyrill 2007, Vivian 1990). Our unique dataset additionally provided insights into disturbance legacies tree hazards. Deadwood cover gradually decreased time since disturbance, from average 50% two years after 25% twelve 15% thirty Vivian. Similarly, height above ground significantly over time, median values dropping 1 2 m immediately 25–30 cm decades later. The stage diameter influenced regeneration, larger diameters logs more advanced (especially less solid/soft very loose stage), facilitating seedling establishment, thus second wave regeneration. About quarter saplings grew disturbance. analysis post-windthrow stand showed increase patterns observed across different sites. Three post-disturbance, number trees had notably increased, reaching 50%. Although Norway spruce remained dominant species, forest composition shifted towards predominance broadleaves, particularly evident lower elevations areas moderate browsing pressure. findings underscore critical recovery promoting uneven-aged mixed structures, thereby enhancing structural diversity, Emphasizing vital importance retaining deadwood, our study suggests its valuable substrate for resilience services likely grow future.
