Professor, U of Alberta. I study the mycorrhizal ecology of forests. Rigor and awe aren't enemies.

A 20 year field experiment shows that in the absence of soil disturbance, tree removal did not cause sig forest floor C losses and mineral soil C increased. I don't know any other expt that so clearly decouples tree removal from soil disturbance. 👍 agupubs.onlinelibrary.wiley.com/doi/10.1029/...

'We have a responsibility to criticize public claims that we believe to be incorrect...' I don't disagree. But criticism can fuel hero stories of the people engaged in questionable research practices. Anyone doing this kind of work should prepare for that outcome.
