Julia Schroeder et al.: Unexpected microbial metabolic responses to elevated temperatures and nitrogen addition in subarctic soils under different land uses

Microbial response to a + 10 °C warming and b N addition per land-use type (shape) expressed as the response ratio (RR) (mean ± sd, n = 9) of cumulative respiration and microbial biomass C after 50 days of incubation, and C directed to microbial respiration and growth, as well as carbon use efficiency (CUE) within 24 h of incubation. RR > 1 indicates an increase of the given parameter upon treatment in relation to the control. Significant responses to treatment (RR ≠ 1) per individual type of land use are marked by an asterisk. Different letters indicate different responses between land-use types at a level of significance of p < 0.05
