The tundra biome is considered the world's coldest biome. The growing season of the tundra tends to range up to 60 days. In the high latitudes in summer the sun remains in the sky at every hour. Because of the short growing season, few trees exist in the tundra. Dominant plant species...

We then added data from the nearest site (shortest geographical distance) and conducted variance partitioning analysis on this expanded dataset (geographic scale = distance from starting site to most distant site). We added sites iteratively until all sites were included i.e., the biome-scale...
Western Alaska's Yukon-Kuskokwim Delta (YKD; US) represents one of the warmest, southernmost parts of the Arctic tundra biome. Much of the region consists of wet, graminoid-dominated meadows, but shrubs are common along active river channels, permafrost plateaus, and upland tundra. We measured...
the consequences of global warming for C release from this biome have been a topic of hot debate over the past decades4,11,16,17. The overall magnitude, persistency and drivers causing variability of the ER increase with warming, however, remain highly uncertain, especially for multidecadal times...

Variation in the effects of diverse herbivore assemblages on tundra vegetation communities across the tundra biome has relevant implications for management, emphasizing that there is no one-size-fits-all recommendation. Depending on the ecosystem processes (and hence the ecosystem services) that managers...
The Arctic is highly sensitive to climate change, and the rise in its near-surface air temperatures has been almost twice the global average. The increased
