Environmental DNA (eDNA) based detection for species monitoring in aquatic systems

By Quentin Mauvisseau from the Natural History Museum, University of Oslo


Due to a number of anthropogenic activities, a dramatic decline in biodiversity is occurring across all earth's ecosystems. Aquatic ecosystems receive considerably less attention than many other habitats and therefore, effective biodiversity monitoring programs are urgently needed to assess the health and state of the endangered and threatened species in these systems. current techniques utilized to survey aquatic ecosystems are often considered ineffective, invasive, time consuming and biased. As a result, the implementation of molecular-based detection tools are attractive options as they are often shown to be more sensitive and cost effective. The use of Environmental DNA (eDNA) detection is one such molecular tool which is showing promising results, due to its high reliability, sensitivity and non-invasiveness characters.
