Hawaiian Arthropod Species Distribution Models and Occurrence Records

Anna E. Hiller assembled georeferenced occurrence records for four Hawaiian arthropod lineages: Laupala, AMC Clade Drosophila, Tetragnatha, and Nesosydne. The data include filtered model inputs and final Maxent species distribution models in ASCII format, based on environmental layers like temperature, rainfall, and vegetation. The models were published in 2017, with some excluded due to low record counts or poor AUC scores.

Use Cases

• Modeling species distributions based on environmental variables like temperature and rainfall.
• Quantifying niche overlap between different arthropod lineages across the Hawaiian archipelago.
• Validating species distribution models using AUC scores and record counts mentioned in the description.
• Analyzing arthropod biogeography based on georeferenced museum specimen records.

Strengths

• Includes distribution models for four distinct arthropod lineages.
• Environmental rasters were resampled to a consistent ~1km resolution.
• Models were selected based on optimum AUC values from trial runs.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Some models were excluded from analyses due to having fewer than 3 records or low AUC scores.
