From: Long-term in situ permafrost thaw effects on bacterial communities and potential aerobic respiration
Potential aerobic respiration of soils from different depths in control and decadal in situ deep-thaw plots during laboratory incubation at 11 °C, measured for 1 week after 1 month pre-incubation, expressed per gram soil dry weight (a) and per gram soil organic matter (b); samples to the right of the dotted line are from permanently frozen soil layers; means ± SE (n = 6). Asterisks denote significant effects (*P < 0.05; ***P < 0.001; n.s. non significant), letters denote significant differences between depths
