Beyond species means - the intraspecific contribution to global wood density variation

Across 109,626 wood density records from 16,829 plant species (GWDD v.2), intraspecific variation explains 15% of global variance, tracks interspecific environmental gradients at 20-30% magnitude, and limits single-plant predictability.

A global map of wood density

The paper creates a high-resolution global map of wood density using species and vegetation data, showing improved accuracy and a wider density range than previous estimates.

A large global soil carbon sink informed by repeated soil samplings

The paper quantifies a global soil organic carbon sink of 1.83 petagrams per year from 1992 to 2020, driven by extratropical and boreal ecosystems, highlighting the importance of soil conservation for climate mitigation.
