Chilean-German researchers show impressive effects on the marine ecosystem. Since several decades, plastics dominate many product and packaging sectors. Unfortunately, more and more of these very durable products are polluting our oceans.
Experts from the Alfred Wegener Institute and the Universities of Oldenburg and Potsdam, Germany have confirmed the existence of a new cryptic amphipod species in the North Sea. For the first time for the description of a new species, they used a level of mitogenomic information, which was normally applied in other areas of genetics.
The discovery of Epimeria frankei was now published in the journal Scientific Reports. In the future, ich flirt kosten level of molecular information could revolutionise biodiversity research. Reports of "new species" in the North Sea, usually relate to animals or algae that were newly introduced by human activities. The discovery of a new amphipod species is proof that ich flirt kosten dating cafe stiftung warentest still unknown organisms lurking in the German Bight.
Raupach from the University of Oldenburg, as well as colleagues from the University of Potsdam, now successfully discovered and described ich flirt kosten previously overlooked species in the North Sea — a rare event, considering that the region is one of the best-studied seas in the world. Scientists create molecular libraries with these barcodes in order möchte sie kennenlernen simplify the identification of species.
When Beermann and Raupach analysed their data, the researchers began to wonder whether they were dealing with only one, but two different species. The new Epimeria species ich flirt kosten named Epimeria frankeiafter Prof. With the discovery and the availability of extensive information on the two species, both species had to be newly described.
But nowadays, modern technologies make the analyses much faster and easier. For the descriptions, the scientists ich flirt kosten use of the entire mitochondrial genome, using state-of-the-art decoding methodologies. In collaboration with the Genomics Team of Prof Michael Hofreiter from the University of Potsdam, they sequenced the genome with cutting-edge technologies. Classifying the importance of their work, Hofreiter and Raupach conclude: From the first indication to the confirmation that they truly detected a previously undiscovered amphipod species, it took the researchers more than six years.
They were originally investigating the species Epimeria cornigera when they took flirten mit deutschen frauen of its sister species.
Until then, Epimeria cornigera was commonly assumed to occur from the Mediterranean Sea to Iceland ich flirt kosten a quite broad but possible distribution. Nevertheless, reliable information on the species' biology was still scarce. As Jan Beermann explains, "We now know that the new species, Epimeria frankeiranges from the Mediterranean to the North Sea, whereas the old species, Epimeria cornigerais more restricted to the northern North Atlantic.
Ich flirt kosten is a small area of overlap in the North Sea were both species can be found. This new discovery underlines that, even today, marine biodiversity can still be underestimated and that molecular methods ich flirt kosten become an indispensable tool for modern biodiversity research. Wedel singles their publication, the researchers combined various molecular genetic and morphological methods to a so-called integrated taxonomic ich flirt kosten "taxonomics".
The authors are convinced that: Jan Beermann, Michael V. Cryptic species in a well-known habitat: The Alfred Wegener Institute pursues research in the polar regions and the oceans of mid and high latitudes. As one of the 18 centres of the Helmholtz Association it coordinates polar research in Germany and provides ships like the research icebreaker Polarstern and stations for the international scientific community.
