Carbon Dioxide Evolution from Subarctic Peatlands in Eastern Canada
T. R. Moore
Measurements of carbon dioxide evolution were made by the alkali absorption method at five poor to very rich fen sites near Schefferville, subarctic Quebec. Daily evolution rates ranged from 1 to 10 g CO2·m−2, in the sequence poor to rich fen, with values dropping to <2 g CO2·m−2·d−1 in early winter. There was a poor correlation between carbon dioxide evolution rates and temperature parameters, probably reflecting the seasonal change in metabolic activities of many subarctic plants. Annual rates of evolution range from 300 to 660 g CO2·m−2, which is in the same sequence as estimated net primary production.
