Tritrophic Interaction Network for Gallwasps and Parasitoids in Sichuan Forests

Environmental Information Data Centre provides pairwise food web relationship data for three trophic groups: Fagaceae trees, Cynipid gallwasps, and parasitoid wasps. The dataset contains 9 tables detailing interactions between galls-trees, parasitoids-trees, and galls-parasitoids for two sites in Sichuan Province. Data was collected from individual tree-level surveys between November 2017 and June 2022 under a NERC Discovery grant.

Use Cases

• Construct food web networks using the pairwise relationship tables to model trophic cascades between trees, gallwasps, and parasitoids.
• Analyze site-specific interaction patterns by comparing the Emeishan and Mianning tables for gall-parasitoid relationships.
• Study community assembly by examining the combined-site tables for galls-trees, parasitoids-trees, and galls-parasitoids.

Strengths

• Data structured into 9 distinct relationship tables for focused analysis of specific trophic links.
• Covers a 5-year temporal range from November 2017 to June 2022.
• Provides site-level granularity with separate tables for Emeishan, Mianning, and combined sites.

Limitations

• Sample size and row counts for each table are unknown, limiting assessment of statistical power.
• Column names and data types are unspecified, requiring schema inspection before analysis.
