7. Stomatal density in Pinus sylvestris as an indicator of temperature rather than co2: evidence from a pan-european transect.

The commonly observed negative relationship between stomatal density (SD) and atmospheric CO2 has led to SD being proposed as an indicator of atmospheric CO2 concentration. The use of SD as a proxy for CO2, however, has been hampered by an insufficient understanding of the intraspecific variation...
