Predatory Wasps Disrupt Ancient Ant-Plant Partnership in Tropical Forests

Scientists found that predatory wasps are increasingly occupying hollow stems of Macaranga pearsonii trees in Malaysian Borneo, disrupting the long-standing relationship between the plants and protective ants.

Why it matters. This change could impact the health and recovery of tropical forests, especially in disturbed landscapes, as the loss of ant defenders may hinder forest regeneration.
