Plant-Soil Interactions Dominate Soil Microbial Respiration And Soil Organic Carbon Sequestration In A Subtropical Moist Evergreen Broadleaved Forest In China, Zhijie Yang

Theses and Dissertations--Plant and Soil Sciences

Tropical forest soils contain one-third of global soil carbon (C). The warm and moist climate in tropical forests leads to rapid soil organic carbon (SOC) decomposition, with the highest soil microbial respiration rates in the world, so even a slight change in soil C and microbial respiration could affect atmospheric carbon dioxide concentration. However, there remains a lack of understanding of the mechanisms driving microbial respiration in tropical forests, due to different climate and biophysical drivers compared to temperate or boreal forests. Furthermore, forest conversions (from natural forests to plantations) are most widespread in tropical regions, leading to a loss …
