More than a thousand far-right supporters have gathered for a rally over the fatal stabbing of a man in the German city of Chemnitz, for which two migrants have been arrested and charged with manslaughter. The number marching was far smaller than the estimated 6, who assembled the day after the August 26 stabbing of year-old Daniel Hillig. Local media reported one far-right supporter was arrested after being identified as having given the stiff-armed Nazi salute at a previous rally, which is banned in Germany, but police headquarters said they had no details on the report. Since the killing of Mr Hillig, the nationalist Alternative for Germany party, or AfD, has sought to mobilise support with its anti-migrant message.
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.
A prominent example is the American comb jellyfish Mnemiopsis leidyi, also called sea walnut. The Latin name of the species is Blackfordia virginica. It is forming a new component of the ecosystem," says Dr. The species Blackfordia virginica was first described scientifically in the waters off the US state of Virginia in Later studies suggest, however, that it originates from the Black Sea.

However, since the canal is the busiest artificial waterway in the world, ships are the most likely culprit.

The scientists were also able to detect specimens outside the canal, in 100 Free Online Dating in Chemnitz, Kiel Fjord.
So far, however, there is no evidence that 100 Free Online Dating in Chemnitz, species is actively recruiting there.
