Title
Effects of elevated CO 2 on the size structure in even‐aged monospecific stands of Chenopodium album
HISAE NAGASHIMA; TAKASHI YAMANO; KOUKI HIKOSAKA; et al. Global Change Biology 2003. doi:10.1046/j.1365-2486.2003.00623.x
Other claims from this paper (9)
- Intervention effect Elevated CO2 significantly enhanced growth under high nutrients.
- Intervention effect Elevated CO2 did not enhance growth under low nutrients.
- Intervention effect Size inequality tended to increase under elevated CO2.
- Intervention effect At early growth stages elevated CO2 shifted stand size distribution toward larger classes.
- Intervention effect At later stages dominant individuals remained larger under elevated CO2.
- Intervention effect At later stages the size difference among subordinate individuals narrowed.
- Association The CO2-related distribution difference was larger at high nutrients.
- Intervention effect At the earliest stage under high nutrients elevated CO2 enhanced size-specific growth rate.
- Mechanism Higher later biomass under elevated CO2 was attributed to larger individuals at the earliest stage.
