We provided a major step forward towards a robust DNA-based bioassessments for
subterranean biodiversity and further emphasise the need for the eDNA community to work together in facilitating a global BRL.

Our review on the conceptual and technical application of eDNA to subterranean ecosystems.
Sacco et al. (2022)

We demonstrate that eDNA can be successfully used to detect subterranean fauna, including the Blind Cave Eel which is listed under Commonwealth conservation legislation.
White et al. (2020)

We identified the western part of the Australia as a region of extremely rich biodiversity for subterranean fauna with a projected 4140 stygobitic and troglobitic species. A significant subterranean fauna is also likely to occur across the eastern part of the continent.
