ABCFlux v2: Arctic–boreal CO <sub>2</sub> and CH <sub>4</sub> monthly flux observations and ancillary information across terrestrial and freshwater ecosystems Open
Measurements of surface-atmosphere carbon dioxide (CO2) and methane (CH4) fluxes have been relatively sparse across the Arctic tundra and boreal biomes, causing significant uncertainties in carbon budget estimates from the region. While th…

Experimental warming and permafrost thaw decrease soil nematode abundance in northern palsa peatlands Open
Global warming is profoundly impacting northern ecosystems, particularly those underlain by permafrost. Permafrost-affected peat plateaus, called palsa peatlands, consist of mounds with peat and mineral soil covering ice lenses. When perma…

Marine‐derived nutrients shape the functional composition of High Arctic plant communities Open
Low temperatures and nutrient limitation have shaped Arctic plant communities, which are now affected by biome‐wise changes in both climate and nutrient cycling. Rising temperatures are favouring taller plant species with more resource‐acq…

Tundra Vegetation Community Type, Not Microclimate, Controls Asynchrony of Above‐ and Below‐Ground Phenology Open
The below‐ground growing season often extends beyond the above‐ground growing season in tundra ecosystems and as the climate warms, shifts in growing seasons are expected. However, we do not yet know to what extent, when and where asynchro…

Environmental Conditions Modulate Warming Effects on Plant Litter Decomposition Globally Open
Empirical studies worldwide show that warming has variable effects on plant litter decomposition, leaving the overall impact of climate change on decomposition uncertain. We conducted a meta‐analysis of 109 experimental warming studies acr…

Implications of climate and litter quality for simulations of litterbag decomposition at high latitudes Open
Litter decomposition is a vital part of the carbon cycle and is thoroughly studied both in the field and with models. Although temporally and spatially limited, litterbag decomposition experiments are often used to calibrate and evaluate s…

Tundra vegetation community, not microclimate, controls asynchrony of above and belowground phenology Open
The below-ground growing season often extends beyond the above-ground growing season in tundra ecosystems. However, we do not yet know where and when this occurs and whether these phenological asynchronies are driven by variation in local …

Disaggregating the Carbon Exchange of Degrading Permafrost Peatlands Using Bayesian Deep Learning Open
Extensive regions in the permafrost zone are projected to become climatically unsuitable to sustain permafrost peatlands over the next century, suggesting transformations in these landscapes that can leave large amounts of permafrost carbo…

Reading tea leaves worldwide: Decoupled drivers of initial litter decomposition mass‐loss rate and stabilization Open
The breakdown of plant material fuels soil functioning and biodiversity. Currently, process understanding of global decomposition patterns and the drivers of such patterns are hampered by the lack of coherent large‐scale datasets. We burie…

Bryophytes dominate plant regulation of soil microclimate in alpine grasslands Open
Soil temperature and moisture are important regulators of a broad range of biotic and abiotic processes in terrestrial ecosystems. Vegetation can, in turn, play a role in regulating soil microclimate, which creates potential for powerful a…

Volatile organic compound release across a permafrost-affected peatland Open
As the permafrost region experiences unprecedented climate warming, accelerated decomposition rates are potentially switching these cold landscapes to a hotspot of carbon emissions. In addition to the more widely studied greenhouse gases, …

Intraspecific trait variability is a key feature underlying high Arctic plant community resistance to climate warming Open
In the high Arctic, plant community species composition generally responds slowly to climate warming, whereas less is known about the community functional trait responses and consequences for ecosystem functioning. The slow species turnove…
