This website looks into the physiological ecology of Carbon Dioxide by using C-13 stable isotope analysis and the large-scale implications of human induced changes in atmoshpheric carbon dioxide.

These techniques are particularly useful in the study of:

--soil organic carbon compostion

--plant water use efficency

--as an indicator of changes in the atmospheric carbon dioxide concentration

--to better understand gas exchange within the canopy
