Invasive Insects Alter Lions' Diet.

A recent study published in the journal American Scientist highlights the impact of invasive insects on ecosystems. The study focuses on the disruption caused by invasive big-headed ants in East Africa's savannas. These ants have overwhelmed native acacia ants, which protect whistling-thorn trees from elephants. As a result, the trees are being destroyed by elephant herds, reducing the coverage for lions when hunting zebras. However, the lion populations have not declined as they have switched to hunting African buffalo. This study emphasizes the importance of fragile mutualisms in maintaining environmental health.
