Functional Guilds, Invasion Status, Endemism, and Rarity of Ants R package AntClassify version 0.1.0 Provides functions for the analysis of ant communities, aiming to standardize workflows in myrmecology. The package automates the assignment of species to functional guilds based on trophic strategies, feeding habits, and foraging behavior, using established classification frameworks (Silva et al., 2015; Silvestre et al., 2003; Delabie et al., 2000), and also includes a novel classification system implemented within the package, developed from ant species occurring in urban environments. It also includes routines to flag exotic species (Vieira, 2025), identify endemic species (Silva et al., 2025), and classify species rarity and rarity forms (Silva et al., 2024). The package reduces manual effort and improves reproducibility, supporting research and biodiversity management of Neotropical ant communities.
