Photosynthesis and Respiration in Forests in Response to Environmental Changes

The isotopic composition of the ecosystem respiration (d13CER) and the isotopic discrimination of the ecosystem (DEco) were retrieved from intensive campaigns (1998 to 2000) and from weekly diurnal sampling (2003) at a boreal forest site (Fraserdale, Canada, 49°53'N, 81°34'W). The results show that d13CER was less sensitive to temperature (T) variation compared with DEco, suggesting that the photosynthesis CO2 flux was likely more sensitive to temperature than the ecosystem respiration CO2 flux during the same period of time at the study site.
