Ants of Uluru-Kata Tjuta National Park in arid Australia: Diversity, faunistic composition and habitat associations

Uluru-Kata Tjuta National Park, a UNESCO World Heritage Site in arid Australia, supports an exceptionally diverse ant fauna, with estimates suggesting around 300 species, including many undescribed. The study recorded 154 ant species from 26 genera, with Melophorus, Monomorium, Iridomyrmex, and Camponotus being the most species-rich. Surprisingly, species richness was higher in structurally simple spinifex grasslands than in eucalypt woodlands, a pattern attributed to remoteness and small patch size. Ant composition varied significantly with vegetation type, distinguishing between grasslands and woodlands, while Iridomyrmex species dominated numerically, contributing 76% of the total ants collected. No exotic species were detected, highlighting the park's unique biodiversity. The study underscores the need for further surveys to better understand ant biodiversity patterns in Australia's central arid zone.
