متن کاملMicrobial community composition and function across an arctic tundra landscape.
Arctic landscapes are characterized by a diversity of ecosystems, which differ in plant species composition, litter biochemistry, and biogeochemical cycling rates. Tundra ecosystems differing in plant composition should contain compositionally and functionally distinct microbial communities that differentially transform dissolved organic matter as it moves downslope from dry, upland to wet, low...
متن کاملThe effect of nutrient deposition on bacterial communities in Arctic tundra soil.
The microbial communities of high-latitude ecosystems are expected to experience rapid changes over the next century due to climate warming and increased deposition of reactive nitrogen, changes that will likely affect microbial community structure and function. In moist acidic tundra (MAT) soils on the North Slope of the Brooks Range, Alaska, substantial losses of C and N were previously obser...
متن کاملSoil bacterial community composition altered by increased nutrient availability in Arctic tundra soils
The pool of soil organic carbon (SOC) in the Arctic is disproportionally large compared to those in other biomes. This large quantity of SOC accumulated over millennia due to slow rates of decomposition relative to net primary productivity. Decomposition is constrained by low temperatures and nutrient concentrations, which limit soil microbial activity. We investigated how nutrients limit bacte...
متن کاملLuteolibacter luojiensis sp. nov., isolated from Arctic tundra soil, and emended description of the genus Luteolibacter.
A yellow-pigmented, Gram-reaction-negative, non-motile, aerobic bacterium, designated DR4-30(T), was isolated from tundra soil near Ny-Ålesund, Svalbard Archipelago, Norway (78° 58' N 12° 03' E). Growth occurred at 4-28 °C (optimum 20-25 °C) and at pH 7-8 (optimum pH 7). Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain DR4-30(T) belongs to the genus Luteolibacter in ...
