Optimization of the eDNA method for marine biodiversity monitoring (EDNA-OPTIMA)

General introduction

The use of eDNA (fully known as environmental DNA or the DNA that remains in the environment where organisms reside or pass through) provides valuable information about the presence and distribution patterns of species in space and time. This method is gaining popularity due to its non-invasive character, but several challenges remain, including false positive and false negative detections, especially in complex marine environments like the North Sea. The eDNA-Optima project aims to eliminate these uncertainties and thus develop a cost-effective and reliable monitoring tool to safeguard the biodiversity and health of the North Sea ecosystem and other marine environments.

Research approach

The focus is a better understanding of the processes that directly influence the distribution, detection, and persistence of eDNA, such as transport, resuspension, and degradation. The project combines laboratory experiments with testing and observations at sea. In addition, technologies are being tested to automate eDNA sampling, using fixed structures and unmanned surface vehicles.

Relevance/Valorisation

Human impacts, new economic activities, and increased maritime mobility can have a broad impact on marine biodiversity. Automating eDNA monitoring holds promise for science, as well as for businesses and policy linked to the blue economy. To ensure the necessary quality standards, a best practices protocol will be developed by the eDNA-Optima researchers.
