It has been suggested that carbon starvation, owing to reduced availability of non-structural carbohydrates (NSCs), is an important contributor to tree mortality during drought in tropical rainforests; however, data from the world’s longest-running experimental drought study presented here show no evidence of carbon starvation, and instead the researchers conclude that impaired water hydraulic processes (involving the transport of water from soil to leaf) have a more important role in triggering tree death from long-term drought.
