Coarse woody debris maintains two distinct and interrelated detrital food webs in forest ecosystems

we conducted an in-situ deadwood decomposition experiment in a subalpine Minjiang fir (Abies faxoniaa) forest from August 2013 to May 2021. Invertebrates on the CWD surface and at the soil–CWD interface were collected and identified after 8 years of decomposition, and the trophic structure of detrital food webs was analyzed using δ13C and δ15N stable isotope methods.
