Fig. 4. Effects of experimental warming on topsoil microbial necromass carbon.
Contents of bacterial (a), fungal (b), and total (c) necromass carbon (C) under warming and control conditions. Total necromass C is calculated as the sum of bacterial and fungal necromass C. d Difference in the proportion of total necromass C to soil organic C between the warming and control treatments. Box represents the interquartile range, with blue and yellow indicating control and warming, respectively. Horizontal line and circle within the box show the median and mean value, respectively. The whisker denotes SD (n = 10, independent samples). Paired samples t-tests (two-sided) were used to determine warming effects on means of microbial necromass C.
