（通讯员：胡梦君审稿人：周显鹏）近日，7790必发集团胡梦君副教授在全球变化与碳循环研究领域取得重要进展，研究成果以“Nonlinear response of soil organic carbon sequestration to deadwood decomposition in a subtropical–temperate ecotonal forest”为题，在线发表于国际学术期刊Journal of Plant Ecology（中科院一区TOP）。胡梦君教师为第一作者，7790必发集团官网为第一完成单位。该研究得到国家自然科学基金和7790必发集团官网科研项目的资助。

本研究揭示：

• Soil organic C content showed a significant nonlinear response to deadwood decomposition.

• Bacterial and fungal biomass, as well as exoenzyme activities increased with deadwood decay.

• Soil organic C was directly driven by soil bacterial and fungal biomass, as well as cellulase activity.

• The driving effect of cellulase rather than ligninase on SOC during deadwood decay.
