Soil biodiversity and the environment

Soils represent a significant reservoir of biological diversity that underpins a broad range of key processes and moderate ecosystem service provision. Our understanding of the role that soil organisms play in ecosystems is still developing, but the increased investigation into biodiversity-ecosystem functioning relationships in soils over the past couple of decades has provided insights that have greatly enhanced our ability to sustainably manage soil biodiversity. In this review, we synthesize emerging knowledge of soil biodiversity as a natural resource that supports the functioning of terrestrial ecosystems and their delivery of ecosystem services. We explore how environmental changes alter soil biodiversity and how this in turn can affect ecosystem processes as well as resistance and resilience to environmental changes. We then discuss ways to include soil biodiversity in management strategies for sustainable production and biodiversity conservation. We conclude by highlighting key research challenges to further improve our knowledge of soil biodiversity and its management.
