Belowground biodiversity is essential for supporting mutiple ecosystem functions of forests.

Forests are crucial for supporting various ecosystem functions and biodiversity, but they are vulnerable to global change drivers such as climate change and land use change. The special issue "How belowground biodiversity affects ecosystem functions of forests" explores the relationship between belowground biodiversity and ecosystem functions in forests. The papers in the special issue cover topics such as the potential drivers of soil microbial biodiversity, the effects of belowground biodiversity on multiple ecosystem functions, and the implications for future research. The findings highlight the importance of belowground biodiversity in maintaining ecosystem functions and provide insights for forest management and biodiversity conservation.
