Bond-Lamberty, B.; Bailey, V. L.; Chen, M.; Gough, C. M.; Vargas, R. (2018): Globally rising soil heterotrophic respiration over recent decades. In: Nature 560 (7716), S. 80–83. DOI: 10.1038/s41586-018-0358-x
"Here we use an updated global soil respiration database9 to show that the observed soil surface RH:RS ratio increased significantly, from 0.54 to 0.63, between 1990 and 2014 (P = 0.009). Three additional lines of evidence provide support for this finding. By analysing two separate global gross primary production datasets10,11, we find that the ratios of both RH and RS to gross primary production have increased over time."
