Other claims from this paper (9)
- Intervention effect Drought reduced gross primary production and plant biomass of Festuca arundinacea relative to well-watered controls.
- Intervention effect Drought reduced net leaf photosynthesis of Festuca arundinacea.
- Intervention effect Drought increased the leaf respiratory fraction of assimilated carbon in Festuca arundinacea.
- Intervention effect Warming increased root respiration of Festuca arundinacea.
- Intervention effect Warming did not affect net leaf photosynthesis or leaf respiration of Festuca arundinacea.
- Observation Festuca arundinacea showed no evidence of thermal acclimation.
- Intervention effect Root respiratory carbon loss was amplified in the combined drought and warming treatment.
- Mechanism Root respiratory carbon loss together with a negative aboveground carbon balance explained an enhanced reduction in plant biomass under combined drought and warming.
- Intervention effect Drought strongly suppressed plant regrowth following clipping in Festuca arundinacea.
