Ecosystems in the far north, including arctic and boreal biomes, are a globally significant
pool of carbon (C). Global change is proposed to influence both C uptake and release in …

In contrast to that of the Pleistocene epoch, between approximately 2.6 million and 10 000
years before present, the extant community of large herbivores in Arctic tundra is species …

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 …

The Arctic tundra is warming rapidly, yet the exact mechanisms linking warming and
observed ecological changes are often unclear. Understanding mechanisms of change …

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

Global environmental change, related to climate change and the deposition of airborne N‐
containing contaminants, has already resulted in shifts in plant community composition …

Abstract Recent Pan‐Arctic shrub expansion has been interpreted as a response to a
warmer climate. However, herbivores can also influence the abundance of shrubs in arctic …

Over millions of years, terrestrial plants have competed for limited resources, defended
themselves against herbivores, and resisted a myriad of environmental stresses. These …

Grazing is the primary land‐use activity on the Tibetan Plateau and can affect soil microbes
and their function through aboveground vegetation removal, animal trampling, and manure …

Lichens and the partners from three different kingdoms are both taxonomically and
physiologically a very diverse group, which makes them interesting from both ecological and …
