Other claims from this paper (10)
- Intervention effect Higher water quantity buffered the negative richness effect of temporal variability.
- Intervention effect Lower temporal variability buffered the negative effect of lower water quantity.
- Association Richness declined as temporal variability of soil moisture rose in glasshouse and field studies.
- Association Evenness was negatively correlated with richness.
- Observation Low-richness, high-evenness communities had low densities and were prone to extinction.
- Mechanism Lower richness under greater temporal variability was attributed to random extinction from lower community density.
- Mechanism Lower richness under greater temporal variability was also attributed to species-specific mortality.
- Intervention effect Final relative abundances differed among water treatments.
- Intervention effect Variability and total water quantity had no separate effect on final relative abundances.
- Intervention effect Upland species were more abundant with more prevalent drought.
