Warming impacts on Arctic and alpine plants: Synthesizing experimental and observational data across the tundra biome

Abstract

Climate change has the potential to substantially alter the composition, structure and function of terrestrial plant communities. A synthetic understanding of these changes is particularly critical in tundra ecosystems, where temperatures are rising most rapidly. Satellite signals suggest a greening of the Arctic is already occurring, but interpretation of this signal in terms of specific biological changes requires complementary in situ observational data. In this talk, I will discuss my research using a diversity of long-term monitoring studies and distributed experiments to understand how the abundance of particular growth forms is changing across the tundra; how these abundance changes alter plant function; and effects of warming plant phenology.
