What happens when Japanese crabs sail into the North Sea and Baltic Sea?
Invasive species were transported by humans into foreign habitats. This can happen for example with ships, were crabs are sitting on the body of the ship or their planktonic stages were carried far away through ballast water. What happened with the native ecosystem, the native species and the marine environment, if an invasive crab species were introduced from Japan into the Baltic Sea? This question is a big topic in the field of global transportations over sea, environmental protection, biodiversity, and in my master thesis 🙂
