Ecological networks of dissolved organic matter and microorganisms under global change.
Microbes regulate the composition and turnover of organic matter. Here we developed a framework called Energy-Diversity-Trait integrative Analysis to quantify how dissolved organic matter and microbes interact along global change drivers of temperature and nutrient enrichment. Negative and positive...

Microbes regulate the composition and turnover of organic matter.
