Complexity revealed in the greening of the Arctic

Isla H. Myers-Smith, +45 more
- 31 Jan 2020 - 
TL;DR: In this paper, a consensus is emerging that the underlying causes and future dynamics of so-called Arctic greening and browning trends are more complex, variable and inherently scale-dependent than previously thought.
Journal ArticleDOI

Large loss of CO2 in winter observed across the northern permafrost region

Susan M. Natali, +81 more
- 21 Oct 2019 - 
TL;DR: In this paper, the authors synthesize regional in situ observations of CO2 flux from Arctic and boreal soils to assess current and future winter carbon losses from the northern permafrost domain.
Journal ArticleDOI

Early stage litter decomposition across biomes

Ika Djukic, +309 more
- 01 Jul 2018 - 
TL;DR: In this article, the potential litter decomposition was investigated by using standardized substrates (Rooibos and Green tea) for comparison of litter mass loss at 336 sites (ranging from
Journal ArticleDOI

Enhanced summer warming reduces fungal decomposer diversity and litter mass loss more strongly in dry than in wet tundra

Casper T. Christiansen, +9 more
- 01 Jan 2017 - 
TL;DR: Although buried soil organic matter decomposition is widely expected to increase with future summer warming, surface litter decay and nutrient turnover rates in both xeric and relatively moist tundra are likely to be significantly restricted by the evaporative drying associated with warmer air temperatures.
Journal ArticleDOI

High arctic heath soil respiration and biogeochemical dynamics during summer and autumn freeze-in – effects of long-term enhanced water and nutrient supply

Casper T. Christiansen, +3 more
- 01 Oct 2012 - 
TL;DR: Autumn soil microbial activity seems tightly linked to growing season plant production through plant-associated carbon pools, and no change in soil organic matter content after 14 years of environmental manipulations is observed, suggesting high ecosystem resistance to environmental changes.
