Influenza dell’aumento della CO2 atmosferica sulla crescita di specie arboree mediterranee

Riassunto: The use of forests to offset increases in atmospheric CO2 is receiving much attention, despite uncertainty over possible changes in growth rates induced by the increases. Analysis of ring widths from five Mediterranean tree species growing at a natural CO2 spring and nearby control site revealed no consistent differences in their radial growth over the last 50 years. This finding is unexpected as existing studies suggest that an increase in above-ground productivity should occur, especially in a water-limited situation. Other resource limitations may have counteracted the positive effect of elevated CO2 under drought stress, or trees may have acclimated to the high CO2.
