  • Well-replicated, ecologically realistic, long-term field experiments were conducted to test the effects of warming on soil microbial diversity. Warming significantly reduced the biodiversity of soil bacteria, fungi and protists by altering environmental selections and biotic interactions, potentially disrupting the functional processes of the soil ecosystem.
