Global Soil Nematode Responses to Heavy Metal Contamination from 51 Studies

Tian compiled a dataset of 2004 independent effect sizes from 51 peer-reviewed publications on soil nematode communities under heavy metal contamination. The data was extracted from tables or digitized from figures and includes information on community structure, life-history traits, and soil properties. The dataset covers multiple ecosystem types including farmlands, forests, grasslands, wetlands, urban soils, and pot experiments.

Use Cases

• Modeling the impact of heavy metal pollution on soil nematode abundance based on reported quantitative data.
• Analyzing shifts in nematode trophic groups or c-p classes along contamination gradients described in the dataset.
• Correlating nematode community metrics with soil physicochemical properties like pH and organic carbon.
• Conducting a global meta-analysis of soil ecological responses to heavy metal exposure using the compiled effect sizes.

Strengths

• Contains 2004 independent effect sizes, providing a substantial basis for statistical analysis.
• Derived from 51 peer-reviewed publications following systematic inclusion criteria for data comparability.
• Covers a wide range of ecosystem types including farmlands, forests, grasslands, wetlands, and urban soils.

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 publication bias inherent to the systematic literature review method.
