Global River Basin Fish Invasion Data with Environmental Factors

Tian Chengzong's dataset analyzes biotic resistance to fish invasions using data from 2,622 river basins worldwide. It quantifies how native species niche differentiation, phylogenetic and functional diversity, richness, and environmental factors contribute to non-native fish richness and occurrence. The dataset was last updated on April 24, 2026.

Use Cases

• Modeling non-native fish richness based on native niche breadth and heterogeneity.
• Analyzing the nonlinear latitudinal gradient of fish invasions.
• Investigating the relationship between human pressure and invasion intensity.
• Testing the invasion paradox by reconciling native richness and invasion metrics.
• Developing integrated invasion management strategies under global change.

Strengths

• Data covers 2,622 river basins worldwide, providing a global scope.
• Includes multiple biotic and environmental factors such as niche differentiation, phylogenetic diversity, human pressure, and basin area.
• Dataset size is 2.2 GB, suggesting substantial data volume.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified as the last update date is April 24, 2026.
