Unknown buffers - which facets of biodiversity stabilize grassland productivity against extreme drought?
The predicted increase in the magnitude and frequency of climate extremes is a driving factor for ecosystem functions and their stability. One of the key buffers stabilizing ecosystem functions in fluctuating environments is biodiversity (Yachi &
Loreau 1999; Loreau & de Mazancourt 2013). Which facets of biodiversity may contribute to the stability (resistance and resilience sensu Grimm & Wissel 1997) of the productivity of temperate grasslands despite extreme drought?
