Snow is an important control of plant community functional composition in oroarctic tundra
Abstract The functional composition of plant communities is a critical modulator of climate change impacts on ecosystems, but it is not a simple function of regional climate. In the Arctic tundra, where climate change is proceeding the most rapidly, communities have not shifted their trait compositi...
