Growth of two peat-forming mosses in subarctic mires: species interactions and effects of simulated climate change
species interactions and effects of simulated climate change. – Oikos 99: 151–160. In patches of co-occurring species in natural plant communities, there is a finely poised balance between species in the ways in which they respond to prevailing moisture and temperature regimes.
