- Intervention effect V. tortilis showed photosynthetic upregulation under elevated CO2, particularly when well watered.
- Intervention effect V. sieberiana showed photosynthetic upregulation under elevated CO2, particularly when well watered.
- Intervention effect Water limitation diminished the photosynthetic responses of the three upregulating species.
- Intervention effect V. robusta downregulated photosynthesis under elevated CO2 at high water availability and improved modestly under dry conditions.
- Intervention effect Senegalia burkei downregulated under elevated CO2 at high water availability.
- Intervention effect Above-ground growth increased significantly only in V. sieberiana under high water supply.
