Development of Taxon-Agnostic Environmental DNA Analysis Technologies and the Establishment of Nature-Positive Indicators

In recent years, “Nature Positive”—the objective of halting and reversing biodiversity loss—has been internationally recognized as a critical global goal. Achieving this goal requires the scientific visualization of biodiversity and an accurate understanding of ecological dynamics.

We aim to develop taxon-agnostic environmental DNA (eDNA) analysis technologies capable of comprehensively detecting all biological taxa within an ecosystem. This approach enables an integrated assessment of biodiversity at the ecosystem level and is expected to contribute significantly to achieving Nature Positive outcomes.

Kobe University is a global leader in eDNA research. For instance, we have developed highly sensitive detection methods that leverage DNA modification states. Because these modification patterns vary according to an organism’s behavior and physiological condition, this approach can provide insights not only into species presence but also into the functional roles and interactions of organisms within their environments.

Furthermore, we collaborate with academic societies across Japan, North America, Europe, and Oceania to promote the global standardization of eDNA methodologies. Looking ahead, we aim to establish an international eDNA consortium, with Kobe University serving as a central hub, thereby contributing to the resolution of global environmental challenges.
