The International Tundra Experiment (ITEX) was founded in 1990 as a network of scientists
studying responses of tundra ecosystems to ambient and experimental climate change at …

Arctic ecosystems have long been thought to be minimal sources of volatile organic
compounds (VOCs) to the atmosphere because of their low plant biomass and cold …

As global temperatures continue to rise, a key uncertainty of terrestrial carbon (C)–climate
feedback is the rate of C loss upon abrupt permafrost thaw. This type of thawing—termed …

Knowledge about changes in plant functional traits is valuable for the mechanistic
understanding of warming effects on ecosystem functions. However, observations have …

Climate change threatens the capacity of peatlands to continue storing carbon (C)
belowground. Microorganisms are crucial in regulating the peatland C sink function, but how …

Seasonal snow cover has an important impact on the difference between soil-and air
temperature because of the insulation effect, and is therefore a key parameter in ecosystem …

Predators may adapt to global warming via behavioural plasticity. However, empirical
evidence showing such adaptations in terrestrial ecosystems is scarce. Here we report …

Understanding the impacts of global warming on keystone species is fundamental to
addressing the threat of climate change to biodiversity. Understory bamboo species play a …

Tundra plants are widely considered to be constrained by cool growing conditions and short
growing seasons. Furthermore, phenological development is generally predicted by daily …

Abstract The Tibetan Plateau holds the world's largest alpine permafrost and is undergoing
an acceleration of warming. Phenological shifts over alpine permafrost in a warmer world …
