Aridity-dependent biodiversity and multi-trophic associations drive soil multifunctionality in dryland ecosystems

Key Points

• Soil multifunctionality is influenced by biodiversity levels and multi-trophic associations within dryland ecosystems.
• The study shows that increased biodiversity can enhance soil functionality, particularly in arid regions.
• Assessment of various dryland ecosystems reveals significant correlations between aridity and ecological interactions.
• These findings highlight the importance of biodiversity for maintaining ecosystem health, particularly under changing climate conditions.
