Greater gains in annual yields from increased plant diversity than losses from experimental drought in two temperate grasslands

Climate change is predicted to result in more severe weather events, including drought, which will affect forage production in agricultural grasslands. We evaluated the effects of an experimentally imposed drought on yields of monocultures and mixtures of intensively managed grassland communities comprising four species with contrasting functional traits (Lolium perenne L., Cichorium intybus L., Trifolium repens L., Trifolium pratense L.)....
