Global studies show that the number of species migrating into foreign ecosystems is constantly increasing. Not all of these species are able to establish themselves in the new environments. However, successful bio-invaders have the potential to cause major changes in their new ecosystems. Also in the Baltic Sea, numerous foreign species have been identified over the past decades.
