Abstract:

The diversity and abundance of below-ground microorganisms and animals play an important role in shaping above-ground biodiversity and helps maintain ecosystem function. Yet, we have a limited understanding of belowground biodiversity, e.g. its spatial/temporal patterns, driving factors and responses to global change and human activities. This knowledge gap is particularly acute for the Tibetan alpine grassland that is sensitive to climate change and occupies 60% of the area of the Tibetan Plateau. Here, we first review recent studies that reported the drivers of patterns in five major soil organism groups, including fungi, bacteria, archaea, nematodes and arthropods on Tibetan alpine grassland. We then focus on the responses of soil biodiversity to climate change and human activities. Finally, we highlight some open questions for future research of soil diversity on the Tibetan alpine grassland. Specifically, we recommend that future studies examine (1) The mechanisms underlying distribution patterns of belowground biodiversity; (2) Links between aboveground and belowground biodiversity; (3) Effects of belowground biodiversity on the health and functioning of ecosystems; (4) Manipulative experiments of belowground biodiversity.
