Global C3/C4 Grass Biomass Allocation Across 631 Species

A global biomass allocation dataset contains 2,747 observations across 631 herbaceous species. It was created by Man Hu and last updated in May 2026 to investigate how aridity mediates nitrogen effects on root-to-shoot ratios in C3 versus C4 plants.

Use Cases

• Model divergent carbon storage responses in grasslands based on photosynthetic pathway (C3 vs. C4) mentioned in the description
• Analyze the interaction between aridity and soil nitrogen on plant biomass allocation strategies
• Investigate the decoupling of drought-response mechanisms and nitrogen-acquisition economies between functional types
• Study the global patterns of root-to-shoot ratio (RSR) in herbaceous species under varying environmental conditions

Strengths

• Dataset integrates 2,747 observations across 631 species, providing a global scope
• Explicitly compares two major photosynthetic pathways (C3 and C4 plants)
• License is CC-BY-4.0, permitting broad reuse with attribution

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Description metadata is limited; actual data quality requires manual inspection after download
