Context-dependent effects of anthropogenic disturbance on δ15N in aquatic consumers: a global meta-analysis

This dataset compiles information for a global meta-analysis on the effects of anthropogenic disturbances on nitrogen isotope signatures (δ¹⁵N) of aquatic consumers. Includes 201 records from 52 published studies covering different types of disturbance (urban, agricultural, pasture). Variables include δ¹⁵N values, disturbance type, trophic guild, climate zone, aquatic ecosystem, and study metadata (author, year, location, and habitat type).
