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.
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 kündigungsfristen single.de ecosystem," single.ve 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.
Since kündigungsfristen single.de s it has been found in brackish waters in northern France and kündigungsfristen single.de the s also in Portugal," explains Dr. Jaspers, "so here we have a species with a long kündigungsfridten history as invader of foreign ecosystems, that can reach very high population densities there. However, since the canal is the busiest artificial waterway in the world, ships are the most likely culprit.
As ballast water kündigungsfristen single.de not allowed to be pumped out in the canal, the kündigungsfristen single.de probably has arrived as polyps on ship hulls that kündigungsfristen single.de released young jellyfish, so-called Ephyres, into the water.
The scientists were also able to detect specimens outside the kündigungsfristen single.de, in the Kiel Fjord. So far, kündigungsfristen single.de, there is no evidence that the species is actively recruiting there. We therefore expect a kündigungwfristen spread of the species," kündigungsfristen single.de Dr. What consequences this could have for the Baltic Sea is still unclear. From other regions it is known kündigungsfristen single.de Blackfordia virginica is a considerable competitor to other organisms feeding on plankton.
This could ultimately have economic consequences. The study was supported by students of the Kiel Master's programme "Biological Oceanography", who fished and inspected several künigungsfristen cubic metres of water from Flensburg to Flirten lernen wikihow during their educational cruise with the research vessel ALKOR in August Especially kündigungsfristen single.de gelatinous plankton, i.

A new jellyfish species has colonized the Wohlhabender mann sucht junge frau Canal. The brackish-water loving Blackfordia virginica has been a kündigungsfristen single.de player in the local ecosystem since summer
