Description:
Net uptake of carbon dioxide (CO2) measured by eddy covariance in a 60- to 80-year-old forest averaged 2.0 +/- 0.4 megagrams of carbon per hectare per year during 1993 to 2000, with interannual variations exceeding 50%. Biometry indicated storage of 1.6 +/- 0.4 megagrams of carbon per hectare per year over 8 years, 60% in live biomass and the balance in coarse woody debris and soils, confirming eddy-covariance results. Weather and seasonal climate (e.g., variations in growing-season length or cloudiness) regulated seasonal and interannual fluctuations of carbon uptake. Legacies of prior disturbance and management, especially stand age and composition, controlled carbon uptake on the decadal time scale, implying that eastern forests could be managed for sequestration of carbon.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Barford, C C -- Wofsy, S C -- Goulden, M L -- Munger, J W -- Pyle, E H -- Urbanski, S P -- Hutyra, L -- Saleska, S R -- Fitzjarrald, D -- Moore, K -- New York, N.Y. -- Science. 2001 Nov 23;294(5547):1688-91.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Engineering and Applied Science and Department of Earth and Planetary Science, Harvard University, Cambridge, MA 02138, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11721047" target="_blank"〉PubMed〈/a〉
