Abstract Sulphur ( S ) and nitrogen N deposition are important drivers of the terrestrial carbon C cycling. We analyzed changes in pools soil tree biomass at a highly acidified spruce site zech R epublic during 15 year period. Total decreased from 5 to 1.1 g m −2 yr −1 between 1995 2009, whereas bulk did not change. Over same period, Oa horizon declined by 116 4.2 , total decrease 47% 42%, respectively. This loss probably originated organic matter OM that had accumulated period high acid...
Nitrogen leaching owing to elevated acid deposition remains the main ecosystem threat worldwide. We aimed contribute understanding of highly variable nitrate losses observed in Europe after retreat. Our study proceeded adjacent beech and spruce forests undergoing acidification recovery differing leaching. reconstructed soil microbial functional characteristics connected with nitrogen carbon cycling based on community composition. results showed that more acidic high content, where...
Abstract Intrinsic water-use efficiency ( iWUE ) of trees is an important component the Earth’s coupled carbon and water cycles. The causes consequences long-term changes in are, however, still poorly understood due to complex interplay between biotic abiotic factors. Inspired by role calcium (Ca) plays plant transpiration, we explore possible linkages tree ring-derived Ca availability five central European forest sites that were affected acidic air pollution. We show increasing was directly...
Mountain forests in National park Bohemian Forest (Czech Republic) were affected by bark beetle attack and windthrows 2004-2008, followed an extensive tree dieback. We evaluated changes the biochemistry of uppermost soil horizons with emphasis on carbon (C) nitrogen (N) cycling a near-natural spruce (Picea abies) mountain forest after dieback, compared it undisturbed control plot similar age, climate, elevation, deposition, N-saturation level, land use history. hypothesised that high litter...
ABSTRACT Anthropogenically enhanced atmospheric sulphur (S) and nitrogen (N) deposition has acidified eutrophied forest ecosystems worldwide. However, both S N mechanisms have an impact on microbial communities the consequences for microbially driven soil functioning differ. We conducted a two-forest stand (Norway spruce European beech) field experiment involving acidification (sulphuric acid addition) (ammonium nitrate) loading their combination. For 4 years, we monitored separate responses...
Abstract Global chronic nitrogen (N) deposition to forests can alleviate ecosystem N limitation, with potentially wide ranging consequences for biodiversity, carbon sequestration, soil and surface water quality, greenhouse gas emissions. However, the ability predict these requires improved quantification of hard-to-measure fluxes, particularly loss retention. Here we combine a unique set long-term catchment budgets in central Europe 15 data reveal fundamental controls over dissolved gaseous...
Alpine meadows are strongly affected by climate change. Increasing air temperature prolongs the growing season and together with changing precipitation patterns alters soil during winter. To estimate effect of change on nutrient cycling, we conducted a field experiment. We transferred undisturbed plant-soil mesocosms from two wind-exposed alpine at ~2100 m a.s.l. to more sheltered plots, situated ~300–400 lower in same valleys. The annual mean was 2°C higher plots soils that were normally...
By incubating the soil without living roots in situ at two spruce forest sites, we simulated effects of tree dieback and interrupted mycorrhizal associations following disturbance on microbiome phosphorus leaching. We observed retreat ectomycorrhizal fungi increased proportion saprotrophs changes community richness Shannon diversity index. This was accompanied by a pronounced decomposition organic matter, associated with an activity carbon-mining hydrolases acid phosphatase. The nonexistent...
Bark beetle disturbances are a critical event in the life cycle of Norway spruce forests. However, our knowledge their effects on ectomycorrhizal fungi (EMF), which play key role forest productivity and nutrient cycling, is still incomplete. Special attention has been paid to dynamics diversity EMF communities managed forests, but studies dealing with disturbed natural stands underrepresented. We conducted study an unmanaged Bohemian Forest (Czech Republic), suffered severe dieback caused by...
We compared two adjacent mature forest ecosystem types (spruce vs. beech) to unravel the fate of assimilated carbon (C) and cycling organic inorganic nitrogen (N) without risk confounding influences climatic site differences when comparing different sites. The stock C in biomass was higher (258 t·ha−1) older (150 years) beech stand younger (80 planted spruce (192 t·ha−1), whereas N pools were comparable (1450 kg·ha−1). Significantly soil measured stand, both floor mineral soil. Cumulative...
Forest areas infected by insects are increasing in Europe and North America due to accelerating climate change. A 2000-2020 mass budget study on major elements (C, N, P, Ca, Mg, K) the atmosphere-plant-soil-water systems of two unmanaged catchments enabled us evaluate changes pools fluxes related tree dieback long-term accumulation/losses during post-glacial period. bark-beetle outbreak killed >75 % all trees a mature mountain spruce forest one catchment dead biomass was left site. similar...
