Extended Data Fig. 3: Relationship between soil CO2 efflux, soil moisture and season, in control and warmed plots.
From: Soil carbon loss by experimental warming in a tropical forest
a, b, Relationship between soil CO2 efflux and soil moisture in warmed (red) and control (blue) plots during the dry (a) and wet (b) seasons. Data were fitted (solid lines) using a quadratic function. c, d, Soil CO2 efflux differences between warmed (red) and control (blue) plots during the dry (c) and wet (d) seasons. Soil CO2 efflux in warmed plots was significantly higher than controls for both dry and wet season, although the difference was greater for the wet season (average difference of 2.8 μmol CO2 m−2 s−1 for the wet season compared to 2.1 μmol CO2 m−2 s−1 for the dry season).
