Roach Grouping Dynamics and Lake Environmental Data

Supplementary data for the paper 'Networking under pressure: environment and population density shape fish grouping structures' contains two primary CSV files. GroupingENVModelV2.csv combines abiotic and biotic lake data with a relative density network metric for BTR and SHAP analysis. ZooplanktonGrouping.csv links the same network metric to pelagic zooplankton biomass and water clarity measurements.

Use Cases

• Modeling fish grouping structures based on environmental variables like temperature and oxygen levels.
• Analyzing the relationship between zooplankton biomass and fish social network density.
• Validating proximity network methods for tracking animal movement in a lake ecosystem.
• Conducing SHAP analysis to interpret the drivers of relative density in fish networks.

Strengths

• Data is directly linked to a peer-reviewed scientific publication, providing context and validation.
• Includes method validation plots and supplementary PDF documentation for reproducibility.
• Released under a permissive CC-BY-4.0 license, facilitating reuse.

Limitations

• Exact row counts and complete column lists are not provided in the available metadata.
• The dataset's temporal and geographic scope for the research lake is not explicitly defined.
• Some water clarity data is noted as 'inferred between measurements', which may introduce uncertainty.
