Arctic extreme winter warming events lead to microbial N immobilization and evergreen shrub N limitation
Autor: Laura Helene Rasmussen, Birgitte Kortegaard Danielsen, Bo Elberling, Michael Kurczy, Elias Ranjbari, Louise Andresen
In Arctic soils, wintertime usually means subzero ground temperatures and only little unfrozen water available below a snow cover. While this period has less active nutrient cycling by microbes, some activity means that winter mineralization of e.g.,

Future Arctic tundra primary productivity and vegetation community composition will partly be determined by nitrogen (N) availability in a warmer climate. N mineralization rates are predicted to increase in winter and summer, but because N demand and

Normalizing time in terms of space: What drives the fate of spring thaw-released nitrogen in a sloping Arctic landscape?
Autor: Laura Helene Rasmussen, Louise H. Mortensen, Per Ambus, Anders Michelsen, Bo Elberling
Publikováno v: Rasmussen, L H, Mortensen, L H, Ambus, P, Michelsen, A & Elberling, B 2022, ' Normalizing time in terms of space : What drives the fate of spring thaw-released nitrogen in a sloping Arctic landscape? ', Soil Biology and Biochemistry, vol. 175, 108840 . https://doi.org/10.1016/j.soilbio.2022.108840
In the Arctic tundra, snowmelt is followed by soil thaw allowing water and dissolved nutrients to move downslope. However, the fate of the released nitrogen (N) remains unclear, which includes the fraction of N that is lost to downslope transport or

Nitrogen Transport in a Tundra Landscape: The Effects of Early and Late Growing Season Lateral N Inputs on Arctic Soil and Plant N Pools and N2O Fluxes
Autor: Laura Helene Rasmussen, Wenxin Zhang, Per Ambus, Per-Erik Jansson, Barbara Kitzler, Bo Elberling
Understanding N budgets of tundra ecosystems is crucial for projecting future changes in plant community composition, greenhouse gas balances and soil N stocks. Winter warming can lead to higher tundra winter nitrogen (N) mineralization rates, while

Slope hydrology and permafrost:The effect of snowmelt N transport on downslope ecosystem
Autor: Weiya Zhang, Per Ambus, Bo Elberling, Laura Helene Rasmussen, Per-Erik Jansson, Anders Michelsen
Publikováno v: Rasmussen, L H, Ambus, P, Zhang, W, Jansson, P E, Michelsen, A & Elberling, B 2020, ' Slope hydrology and permafrost : The effect of snowmelt N transport on downslope ecosystem ', EGU General Assembly 2020, 04/05/2020-08/05/2020 . https://doi.org/10.5194/egusphere-egu2020-2927
In the permafrost-affected landscape, surface and near-surface water movement links areas of higher elevation with lowlands and surface water bodies. Water supply is dominated by snow melt and is thus highly seasonal, as most water moves on the froze
