In this study carbon dioxide and methane fluxes were measured in three dominant vegetational communities in a taiga peatland located within the zone of discontinuous permafrost in the Alaskan interior. Trace gas (CO2 and CH4 ) flux measurements were made across spatial scales from excised roots to in situ peatland ecosystems. Temperatures increases and local water tables decreases from 1991 to 1993 affected methane emission two sites. Mid season methane emissions in the tussock meadow was fairly constant, ranging from 56.3 ± 29.8 mg CH4 /m2 /day in 1991 to 62.3 ± 37.2 mg CH 4 /m2 /day in 1993. Emissions dropped in the drier dwarf spruce scrub from 12.2 ± 8.1 mg CH4 /m2 /day in 1991 to zero in 1993. In the floating...
