S. invicta EI–TT–TIC Integrated Dataset (v1.1)

This dataset provides all processed inputs, derived indices, and analysis code used to quantify the ecological suitability, invasion threat, and crop-related economic impacts of the invasive fire ant Solenopsis invicta. The repository includes (i) processed occurrence records, climate variables, crop yield and price data compiled from publicly available sources, and (ii) derived spatial indices generated in this study, including the Ecological Suitability Index (EI), Total Invasion Threat (TT), and Threat Intrusion Cost (TIC) for multiple time periods.
