Researchers from Edith Cowan University used DNA from poop samples to study the diet of the critically endangered Gilbert's potoroo. This helped them identify suitable new habitats for the species.

The Gilbert's potoroo, a small marsupial found only in Western Australia, has fewer than 150 animals left in the wild. To save this species, scientists from Edith Cowan University and the Department of Biodiversity, Conservation and Attractions are working together.

The team used environmental DNA (eDNA) metabarcoding on scat samples to investigate the potoroo's diet. This technique is non-invasive and allows researchers to study animals without disturbing them. The scientists found that the diets of more common fungi-eating mammals, such as quokkas and bush rats, overlapped with the Gilbert's potoroo.

The team also examined whether the habitats used by these species were similar. They found that the quokka and potoroo shared similar habitat use. Based on their results, they recommend focusing on areas where all three species persist together as an indicator of suitable food or habitat for future potoroo translocation sites.

The Gilbert's potoroo was once thought to be extinct before being rediscovered in 1994. Since then, conservation teams have tried several approaches to increase the population. Wild-to-wild translocations are now a crucial step in securing the species' future.

Why It Matters

This research matters because it can help us better understand and protect endangered species like the Gilbert's potoroo. As students in India, you might be interested in learning about conservation efforts that involve using DNA from poop samples to study animal diets.
