New paper in @science.org !
Where and when did the #multiyear-droughts occur around the world? Have they become more prevailing? We identified over 10,000 such events and found that they have been increasingly occupying the terrestrial land. (1/6)

#MultiyearDroughts, it is nice to see studies with distinct designs and used data converge to similar results — "25-30%" seems to be a key range, in this study about the measured reduction of primary production in grassland and in our previous study with kNDVI www.science.org/doi/10.1126/... .
As droughts become longer and more intense, their toll on ecosystems could be far greater than we thought. Our new paper in @science.org shows how prolonged & extreme droughts cause dramatic, cumulative losses in ecosystem productivity across the globe www.science.org/doi/10.1126/...

Revisiting the cry-for-help hypothesis in plant–microbe interactions
The ‘cry-for-help hypothesis’ (CHH) is broadly used to study how root exudate modulation under stress influences recruitment of beneficial microbes in the rhizosphere. Here, we explored common misconceptions and limitations of the CHH and advocate for the reassessment of this prevalent hypothesis to unfold the ecological complexities of plant–microbe interactions.
