The authors performed a very interesting drought experiment on temperate grass monocultures, in which they assessed the effects of timing of drought on resistance, recovery and overall, annual (A)NPP. They found the lowest drought sensitivity in spring, and overcompensating post-drought growth which to a substantial extent cancelled out immediate impacts of drought on overall ANPP. By unravelling global change effects (drought) on components of ecosystem function (ANPP), the study matches the scope of the journal.
