- Intervention effect Smaller pots, less water, and less nutrient addition reduced maximum size in both species.
- Intervention effect The three restrictive conditions decreased growth rates.
- Intervention effect The three restrictive conditions delayed most rapid growth.
- Intervention effect Limited soil volume or low nutrients increased root to shoot ratios.
- Intervention effect Neither species changed root allocation with water availability.
- Observation B. tectorum population growth was 2 to 3.5 times that of B. briziformis.
- Observation B. tectorum plants were larger than B. briziformis.
- Observation B. tectorum had lower leaf nitrogen than B. briziformis.
- Observation B. tectorum produced nearly three times as many seeds as B. briziformis.

- Intervention effect Fertilization increased seed production at one site.
- Intervention effect Watered plants were more depleted in 13C at one site.
