Influence of Myrmecophytic <i>Acacia drepanolobium</i> on the Composition and Growth of Surrounding Herbaceous Vegetation. [PDF]
In areas facing intense herbivory pressure, heavily defended trees like Acacia drepanolobium may serve as nurse plants, creating refugia microhabitats for the growth of vulnerable plants. Such refugia habitats promote diversity across the landscape and may also serve as recolonization nuclei for rare species.
