ABSTRACT Peatland vegetation is composed mostly of mosses, graminoids and ericoid shrubs, these have a distinct impact on peat biogeochemistry. We studied variation in soil microbial communities related to natural peatland microhabitats dominated by Sphagnum, cotton-grass blueberry. hypothesized that such will be occupied structurally functionally different communities, which vary further during the season due changes temperature photosynthetic activity plant dominants. This was addressed...
Abstract. The unique and fragile High Arctic ecosystems are vulnerable to global climate warming. elucidation of factors driving microbial distribution activity in arctic soils is essential for a comprehensive understanding ecosystem functioning its response environmental change. goals this study were investigate biomass activity, community structure (MCS), their controls along three elevational transects the coastal mountains Billefjorden, central Svalbard. Soils from four different...
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...
In peatlands, decomposition of organic matter is limited by harsh environmental conditions and low decomposability the plant material. Shifting vegetation composition from Sphagnum towards vascular plants expected in response to climate change, which will lead increased root exudate flux soil stimulation microbial growth activity. We aimed evaluate effect exudates on recalcitrant dissolved carbon (DOC) identify microorganisms involved this process. The exudation was mimicked an addition a...
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...
The rhizosphere is a hot spot of soil microbial activity and largely fed by root exudation. carbon (C) exudation flux, coupled with plant growth, considered strategy plants to facilitate nutrient uptake. C accompanied release nutrients. Nitrogen (N) phosphorus (P) co-limit the productivity plant-microbial system. Therefore, C:N:P stoichiometry exudates should be linked economies, functional traits (PFT) availability. We aimed identify strongest links in among all components. A total eight...
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...
