Environmental DNA preserved in marine sediment for detecting jellyfish blooms after a tsunami
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 experiment, juvenile jack mackerel (Trachurus japonicus) were kept in flow-through tanks with marine sediment for two weeks. Water and sediment samples from the tanks…
Last weekend, dozens of swimmers reported complaints. The municipality of Schouwen-Duiveland reported that it was probably the weever.
