Synopsis

Habitat fragmentation driven by urbanization exerts selective pressures on fauna. This study analyzed potential morphological changes in the ant Paraponera clavata along an urban–rural gradient, with the overarching goal of identifying adaptations in functional traits linked to foraging. The methodology involved sampling in two contrasting environments (urban in Tena and rural in Ahuano) and using geometric morphometrics to quantify variation in the head capsule and left mandible of 144 specimens. The results revealed significant differences in head capsule shape between urban and rural environments, while the mandible exhibited significant variation across all comparisons. We conclude that urbanization induces differential morphological adaptations in structures critical for foraging, demonstrating this species’ plasticity in responding to novel resource conditions in transformed landscapes.
