Most applications of land cover maps that have been derived from satellite data over the
Arctic require higher thematic detail than available in current global maps. A range of …

Advancing phenology in response to global warming has been reported across biomes,,
raising concerns about the temporal uncoupling of trophic interactions,. Concurrently, widely …

Thawing permafrost represents a poorly understood feedback mechanism of climate change
in the Arctic, but with a potential impact owing to stored carbon being mobilized,,,,. We have …

Permafrost soils contain nearly twice as much carbon as the atmosphere. When these soils
thaw, large quantities of carbon are lost, mainly in the form of methane and carbon …

Many alpine and subalpine plant species exhibit phenological advancements in association
with earlier snowmelt. While the phenology of some plant species does not advance beyond …

Here we present results from a field experiment in an Arctic wetland situated in Zackenberg,
NE Greenland. During one growing season we investigated how dominance of the sedge …

Arctic tundra soils serve as potentially important but poorly understood sinks of atmospheric
methane (CH4), a powerful greenhouse gas,,,,. Numerical simulations project a net increase …

Rapid temperature and precipitation changes in High Arctic tundra ecosystems are altering
the biogeochemical cycles of carbon (C) and nitrogen (N), but in ways that are difficult to …

The Arctic is getting warmer and wetter. Here, we document two independent examples of
how associated extreme precipitation patterns have severe implications for high Arctic …

The Arctic is experiencing some of the fastest rates of warming on the planet. Although many
studies have documented responses to such warming by individual species, the …
