Extreme drought stress shifts net facilitation to neutral interactions between shrubs and sub‐canopy plants in an arid desert Open
The stress gradient hypothesis (SGH) predicts that the importance or intensity of competition and facilitation will change inversely along abiotic stress gradients. It was originally postulated that increasing environmental stress can indu…
