Root carbon pools across a post-fire tree density gradient in far northeastern Siberia, 2015 - 2017 ...
Fire severity is increasing in larch forests of the Siberian Arctic as climate warms, and initial fire impacts on tree demographic processes could be an especially important determinant of long-term forest structure and carbon (C) dynamics. We hypothesized that changes in post-fire larch recruitment...
