Variable sensitivity of plant communities in Iceland to experimental warming,
Global Change Biology,
11: 553-563
Facing an increased threat of rapid climate change in cold-climate regions, it is important
to understand the sensitivity of plant communities both in terms of degree and direction
of community change. We studied responses to 3–5 years of moderate experimental
warming by open-top chambers in two widespread but contrasting tundra communities
in Iceland. In a species-poor and nutrient-deficient moss heath, dominated by
Racomitrium lanuginosum, mean daily air temperatures at surface were 1–2 …
