Global Soil Biodiversity Database Across Multiple Trophic Levels

A global database integrates over 5,000 soil samples from amplicon and metagenomics studies. It covers multitrophic soil biodiversity, including archaea, bacteria, fungi, protists, and invertebrates. The dataset was authored by Gui-Feng Gao and last updated in May 2026.

Use Cases

• Test the universality of the latitudinal diversity gradient based on global soil biodiversity data.
• Analyze community turnover and beta diversity patterns across latitudes.
• Model the influence of local edaphic properties like soil carbon, nitrogen, and pH on biodiversity.
• Investigate how global climatic variables override latitude in explaining soil biodiversity variation.
• Study nutrient availability as a mediator of community assembly across regions.

Strengths

• Integrates two independent global databases comprising over 5,000 soil samples.
• Covers multitrophic soil biodiversity across five major groups: archaea, bacteria, fungi, protists, and invertebrates.
• Includes both amplicon and metagenomics data types.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the sampling locations of the integrated databases.
