abstract

  • CO2 efflux from tussock tundra in Alaska that had been exposed to elevated CO2 for 2.5 growing seasons was measured to assess the effect of long- and short-term CO2 enrichment on soil respiration. Long-term treatments were: 348, 514, and 683 μll-1 CO2 and 680 μll-1 CO2+4°C above ambient. Measurements were made at 5 CO2 concentrations between 87 and 680 μll-1 CO2. Neither long- or short-term CO2 enrichment significantly affected soil CO2 efflux. Tundra developed at elevated temperature and 680 μll-1 CO2 had slightly higher, but not statistically different, mean respiration rates compared to untreated tundra and to tundra under CO2 control alone. © 1986 Martinus Nijhoff Publishers.
