Other claims from this paper (8)
- Intervention effect Damaged milkweed plants lost mass compared with undamaged controls.
- Intervention effect Damaged milkweed plants had reduced root:shoot ratios compared with controls.
- Intervention effect The effect of damage on total mass, stem investment and relative growth rate varied among genetic families of common milkweed.
- Observation Under control conditions, plants from colder climates grew larger than plants from warmer climates.
- Observation Under control conditions, plants from colder climates invested less in stems and roots than plants from warmer climates.
- Observation Plants from colder climates were less able to compensate for damage in terms of biomass than plants from warmer climates.
- Intervention effect Plants from warmer climates tended to increase their growth rate and stem investment in response to damage.
- Mechanism The authors suspect that differences in developmental phenology among plants from different climates affect the impact of damage and the potential for compensatory growth.
