Microbial Assemblages in Soil Microbial Succession After Glacial Retreat in Svalbard (High Arctic)
It is shown that nitrogen and water content are the main factors affecting bacterial abundance and overall soil respiration, and of the studied habitats cryoconite sediments are the most suitable ones for the development of microbial assemblages. Expand
Microbial processes and carbon‐isotope fractionation in tropical and temperate grassland soils
1. The carbon content and δ13C value of soil organic carbon (SOC), microbial biomass (Cmic) and respired CO2 were measured in a range of grassland soils from tropical and temperate biomes toExpand
When the forest dies: the response of forest soil fungi to a bark beetle-induced tree dieback
This work examines the structural and functional response of the litter and soil microbial community in a Picea abies forest to tree dieback following an invasion of the bark beetle Ips typographus, with a specific focus on the fungal community. Expand
Accumulation of carbon, nitrogen and phosphorus during soil formation on alder spoil heaps after brown-coal mining, near Sokolov (Czech Republic)
The accumulation of carbon (C), nitrogen (N) and phosphorus (P) and their vertical distribution in the soil profile in relation to site age were studied in a chronosequence of 19 sites on reclaimedExpand
Effect of pH and dissolved organic matter on the abundance of nirK and nirS denitrifiers in spruce forest soil
Acid N depositions in the Bohemian Forest during the second half of the last century caused enormous soil acidification which led to the leaching of essential nutrients including nitrates. WeExpand
Potential carbon emissions dominated by carbon dioxide from thawed permafrost soils
A meta-analysis of soil incubation studies from the permafrost zone suggests that thawing under aerobic conditions, which releases CO2, will strengthen the permafrost carbon feedback more thanExpand
Quality and potential biodegradability of soil organic matter preserved in permafrost of Siberian tussock tundra
Abstract Soil organic matter (SOM) quality and biodegradability the permafrost underlying Siberian wet tussock tundra (Kolyma river basin, northeast Siberia) were analyzed and compared to theExpand
Distinct microbial communities associated with buried soils in the Siberian tundra
The study expands the knowledge on the microbial community structure in soils of Northern latitude permafrost regions, and attributes the delayed decomposition of SOM in buried soils to specific microbial taxa, and particularly to a decrease in abundance and activity of ECM fungi, and to the extent to which bacterial decomposers are able to act as their functional substitutes.

Microbial community structure and ecology of subglacial sediments in two polythermal Svalbard glaciers characterized by epifluorescence microscopy and PLFA
The results suggest that the subglacial microbial populations can be divided into two groups: autochthonous microorganims (chemoheterotrophic bacteria) and allochth onous that retain the ability to proliferate and give rise to active population when conditions become favorable. Expand
