Global climate change is expected to increase rainfall variability, potentially increasing the frequency of extreme droughts during this century. Intensified drought will impact ecosystem functioning, with many ecosystems expected to experience a reduction in primary productivity. Understanding the magnitude of these impacts is especially important in grassland ecosystems as they are particularly sensitive to precipitation variability. The negative impacts of extreme drought on grassland productivity have been widely documented, however, the underlying mechanisms of drought sensitivity remain understudied.
