High Arctic plant community resists 15 years of experimental warming
Summary 1. Identifying plant communities that are resistant to climate change will be critical for developing accurate, wide‐scale vegetation change predictions. Most northern plant communities, especially tundra, have shown strong responses to experimental and observed warming. 2. Experimental warm...
