The use of open‐top chambers in forests for evaluating warming effects on herbaceous understorey plants
Abstract Open‐top chambers (OTCs) are widely used experimental warming devices in open‐field ecosystems such as tundra and alpine heath. However, knowledge of their performance in temperate deciduous forest ecosystems is largely lacking. The application of OTCs in forests might become important in t...

Abstract Open‐top chambers (OTCs) are widely used experimental warming devices in open‐field ecosystems such as tundra and alpine heath.
