Is the loss of Australian digging mammals contributing to a deterioration in ecosystem function?

Australia’s once common digging mammals that played an important role in ecosystem function, have been largely lost from our landscape. Around half of digging mammal species are now extinct or under conservation threat, and those that still exist have very contracted ranges. Bioturbation (digging and scratching) significantly alters soil processes, altering the chemical and structural …
