1. 12

   Burrowing bettongs possess specially adapted hind feet with elongated metatarsals that enable them to hop up to two meters in a single bound when escaping predators.

   Scattered seeds and spores from fungi germinate more successfully in areas where burrowing bettongs have foraged, demonstrating their role as ecosystem engineers beyond simple food dispersal.

   Predation by introduced species reduces burrowing bettong survival rates to approximately 50 percent annually on mainland Australian reserves compared to less than 20 percent on predator-free islands.
