ECOSYTEM ECOLOGY- ORIGINAL PAPER The effect of temperature on growth and competition
Abstract Peat bogs play a large role in the global sequestration of C, and are often dominated by different Sphagnum species. Therefore, it is crucial to understand how Sphagnum vegetation in peat bogs will respond to global warming. We performed a greenhouse experiment to study the effect of four t...
