Clean water: fewer lives in the Wadden Sea today

Where the water is cleaner, there are more animals – one might think. A research team from the Senckenberg am Meer Research Institute and the University of Oldenburg has now shown that this is not always and everywhere the case. The group led by Anja Singer investigated how species diversity and total biomass have changed in the East Frisian Wadden Sea compared to the 1980s. They note a clear downward trend: Stocks of the then-dominant species, the common mud snail, tree tubeworms and mud crustaceans, have fallen by more than 80 percent. According to the study, the total biomass has almost halved, and the number of individuals per square meter has shrunk by 31 percent. In the journal Frontiers in Marine Science. has been published.
