Over the past decade, the Arctic has warmed by 0.75° C, far outpacing the global average,
while Antarctic temperatures have remained comparatively stable. As Earth approaches 2° …

Permafrost regions at high latitudes and altitudes store about half of the Earth's soil organic
carbon (SOC). These areas are also some of the most intensely affected by anthropogenic …

Upward shifts of mountain vegetation lag behind rates of climate warming, partly related to
interconnected changes belowground. Here, we unravel above-and belowground linkages …

Soils in Arctic and boreal ecosystems store twice as much carbon as the atmosphere, a
portion of which may be released as high-latitude soils warm. Some of the uncertainty in the …

Abstract Ecosystems in the North American Arctic-Boreal Zone (ABZ) experience a diverse
set of disturbances associated with wildfire, permafrost dynamics, geomorphic processes …

In the light of daunting global sustainability challenges such as climate change, biodiversity
loss and food security, improving our understanding of the complex dynamics of the Earth …

Temperature and precipitation are primary regulators of plant phenology. However, our
knowledge of how these factors might interact to affect plant phenology is incomplete. The …

The semi-domesticated nature of the reindeer (Rangifer tarandus L.) makes it a distinct case
among the world's herbivores. Here, we review the literature on how reindeer shape …

Arctic terrestrial herbivores influence tundra carbon and nutrient dynamics through their
consumption of resources, waste production, and habitat‐modifying behaviors. The strength …

Anthropogenic nutrient enrichment and shifts in herbivory can lead to dramatic changes in
the composition and diversity of aboveground plant communities. In turn, this can alter seed …
