Other claims from this paper (8)
- Intervention effect Larix decidua tree ring increments were larger under elevated CO2 during the experiment.
- Intervention effect Pinus tree ring increments showed no larger response under elevated CO2.
- Intervention effect After 9 years of elevated CO2, Larix leaf canopy cover, stem basal area and total new shoot production were overall greater.
- Intervention effect Larix ring width was significantly stimulated by elevated CO2 in some treatment years.
- Association Larix ring width was stimulated more by elevated CO2 in years with relatively high spring temperatures and an early snowmelt date.
- Association The magnitude of CO2 stimulation of Larix was larger after relatively high temperatures and high solar radiation in the preceding growing season.
- Association Larix is expected to gain a competitive advantage over less responsive species, such as co-occurring Pinus, under future CO2 concentrations.
- Association Stimulation of Larix growth may be especially pronounced in a future warmer climate.
