Occurrence Data and Models for Two Invasive White-Footed Ants

114,971 files contain occurrence records, R scripts, and results for Technomyrmex albipes and T. brunneus. The dataset supports analyses of climatic niche divergence and future contact zones under CMIP6 climate scenarios for 2050 and 2090. It includes species distribution models built with Maxent using specific WorldClim bioclimatic variables for each species.

Use Cases

• Running species distribution models (SDMs) for Technomyrmex ants using the provided R scripts and occurrence data.
• Analyzing climatic niche overlap between T. albipes and T. brunneus based on PCA summaries and niche metrics.
• Projecting future suitable habitats under SSP126, SSP245, SSP370, and SSP585 scenarios for 2050 and 2090.
• Comparing latitude and elevation distributions of the two ant species using the Taiwan-specific occurrence datasets.

Strengths

• Includes a complete reproducible workflow with data, code (R scripts), and selected results (114,971 files).
• Models use specific, documented bioclimatic predictor sets for each species (e.g., bio02, bio03, bio04 for T. albipes).
• Future projections are based on multiple standard CMIP6 scenarios (SSP126, SSP245, SSP370, SSP585) for two time horizons.
• Released under a permissive CC-BY-4.0 license, facilitating reuse and modification.

Limitations

• Critical input data (WorldClim and CMIP6 climate rasters) are not included and must be sourced separately by users.
• The exact row count for the occurrence records is not specified in the provided metadata.
• The dataset's description is highly specific to the supporting manuscript, which may limit broader interpretability without context.
