Adaptions of whistling thorns

Whistling thorns, specifically Acacia drepanolobium, have evolved several adaptations to survive in their environment. These trees feature hollow thorns that serve as nesting sites for ants, which provide protection against herbivores in exchange for shelter and food. Additionally, the trees produce extrafloral nectar to attract these ants, enhancing their mutualistic relationship. Their ability to thrive in nutrient-poor soils and withstand drought conditions further contributes to their resilience in savanna ecosystems.
