Predictor complexity and feature selection affect Maxent model transferability: evidence from global freshwater invasive species

This dataset contains the following:

Occurrence datasets of five global freshwater invasive species (African sharptooth catfish Clarias gariepinus, Mozambique tilapia Oreochromis mossambicus, American bullfrog Lithobates catesbeianus, red swamp crayfish Procambarus clarkii, and Australian redclaw crayfish Cherax quadricarinatus)
Background points for presence-only ecological niche modelling (e.g., Maxent)
Example R script (with annotations inline) to conduct model tuning and transferability assessments using Maxent

Methods
Occurence datasets for five species were aggregated from published literature, online databases, and natural history museum collections (see Appendix S1 in Supporting Information of journal article for data sources). Occurrences were further thinned using the 'thin' function (R package 'spThin') with a thinning distance of 50 km.
