Hot spots for nitrous oxide emissions found in different types of permafrost peatlands
ME Marushchak, A Pitkämäki, H Koponen… - Global Change …, 2011 - Wiley Online Library
Recent findings on large nitrous oxide (N2O) emissions from permafrost peatlands have
shown that tundra soils can support high N2O release, which is on the contrary to what was …

Soil microbial biomass, nutrient availability and nitrogen mineralization potential among vegetation-types in a low arctic tundra landscape
Arctic plant communities vary greatly over short distances due to heterogeneities in
topography and hydrological conditions across the landscape. Recent evidence suggests …

Microbiogeochemical traits to identify nitrogen hotspots in permafrost regions
Permafrost-affected tundra soils are large carbon (C) and nitrogen (N) reservoirs. However,
N is largely bound in soil organic matter (SOM), and ecosystems generally have low N …

The influence of vegetation type on the dominant soil bacteria, archaea, and fungi in a low arctic tundra landscape
Arctic vegetation communities vary greatly over short distances due to landscape
heterogeneities in topography and hydrological conditions, but corresponding patterns and …

The response of organic matter mineralisation to nutrient and substrate additions in sub-arctic soils
Global warming in the Arctic may alter decomposition rates in Arctic soils and therefore
nutrient availability. In addition, changes in the length of the growing season may increase …

Root trait variation along a sub‐arctic tundra elevational gradient
Elevational gradients are useful for predicting how plant communities respond to global
warming, because communities at lower elevations experience warmer temperatures. Fine …

Environmental factors and traits that drive plant litter decomposition do not determine home‐field advantage effects
Summary The 'home‐field advantage'(HFA) hypothesis predicts that plant litter is
decomposed faster than expected underneath the plant from which it originates ('home') …

Plant and microbial responses to nitrogen and phosphorus addition across an elevational gradient in subarctic tundra
Temperature and nutrients are major limiting factors in subarctic tundra. Experimental
manipulation of nutrient availability along elevational gradients (and thus temperature) can …

Invasive earthworms unlock arctic plant nitrogen limitation
Arctic plant growth is predominantly nitrogen (N) limited. This limitation is generally
attributed to slow soil microbial processes due to low temperatures. Here, we show that …
