Environmental DNA preserved in marine sediment for detecting jellyfish blooms after a tsunami

Abstract Environmental DNA (eDNA) can be a powerful tool for detecting the distribution and abundance of target species. This study aimed to test the longevity of eDNA in marine sediment through a tank experiment and to use this information to reconstruct past faunal occurrence. In the tank experime...
