Australian researchers are using environmental DNA techniques on feces samples to identify suitable habitats for the critically endangered Gilbert's potoroo. The work aims to establish new populations of the marsupial, which numbers fewer than 150 in the wild. The approach could improve translocation efforts after past setbacks including a major bushfire.
Scientists from Edith Cowan University and the Department of Biodiversity, Conservation and Attractions analyzed scat samples from the Gilbert's potoroo and related species. They applied eDNA metabarcoding to determine the fungi the animals consume. This non-invasive method revealed dietary overlaps with quokkas, quendas and bush rats, helping pinpoint areas with adequate food resources for future relocation sites.
