Open top chambers (OTCs) were adopted as the recommended warming mechanism by the
International Tundra Experiment network in the early 1990s. Since then, OTCs have been …

Global climate change is already having significant impacts on arctic and alpine
ecosystems, and ongoing increases in temperature and altered precipitation patterns will …

Climate warming is changing the aboveground phenology of plants around the world.
However, the effects of warming on the belowground phenology of plants remain relatively …

The response of northern tundra plant communities to warming temperatures is of critical
concern because permafrost ecosystems play a key role in global carbon (C) storage, and …

Global climate change is predicted to have large impacts on the phenology and
reproduction of alpine plants, which will have important implications for plant demography …

We investigated experimental warming and simulated grazing (clip**) effects on
rangeland quality, as indicated by vegetation production and nutritive quality, in winter …

Recent changes in climate have led to significant shifts in phenology, with many studies
demonstrating advanced phenology in response to warming temperatures. The rate of …

Observations of a longer growing season through earlier plant growth in temperate to polar
regions have been thought to be a response to climate warming,,,,. However, data from …

Because the phenology of trees is strongly driven by environmental factors such as
temperature, climate change has already altered the vegetative and repro‐ductive …

The International Tundra Experiment (ITEX) was founded in 1990 as a network of scientists
