Social-Ecological Network Analysis of Marine Fish Incursions in Lake Gatun

Supplementary materials support a social-ecological network (SEN) analysis of marine fish introductions into Lake Gatun, Panama, following the canal expansion. The dataset likely contains ecological and interview-derived data to model changes in fish community composition, trophic links, and impacts on fishers' livelihoods and income. Network indices reveal decreased connectivity and resilience, with variable economic susceptibility between small-scale fishers and recreational guides.

Use Cases

• Modeling social-ecological network resilience based on reported changes in fish populations and fisher income.
• Analyzing shifts in target species diversity between small-scale and recreational fishing sectors.
• Assessing the adaptive capacity of fishers to biological invasions using income diversification metrics.
• Studying trophic link changes in a freshwater ecosystem following marine species incursions.

Strengths

• Dataset size is 1,113,416 bytes, indicating substantive supplementary material.
• Explicitly licensed under CC-BY-4.0, permitting broad reuse with attribution.
• Framework integrates ecological data with stakeholder interview information for a coupled human-nature analysis.

Limitations

• Column names and row counts are not provided, limiting understanding of the data structure.
• The dataset consists of supplementary materials; the core analysis data may not be fully included.
