Divergent patterns of richness and density in the global soil seed bank.

Soil seed bank species richness and seed density show divergent global patterns, with habitat degradation reducing richness and affecting ecosystem recovery potential.

• Why it matters: Understanding these patterns is crucial because soil seed banks influence plant community resilience and biodiversity, yet their global variability and response to degradation are poorly understood.
• What they did: The study analyzed components of soil seed bank diversity across different biomes and ecosystems, focusing on species richness and seed density, despite high uncertainty at small scales.
• The result: Findings reveal that habitat degradation consistently lowers seed richness, especially in tropical and Mediterranean regions, highlighting implications for biodiversity conservation and ecosystem restoration.
