Cryptic species in marine polychaete and their independent introduction from North America to Europe.
It is hypothesized that both European cryptic species of Marenzelleria may originally have been introduced to both the North Sea and the Baltic Sea but that neither of them was able to proliferate in both water bodies owing to their differential physiological performances at high and low salinities. Expand
Molecular identification key based on PCR/RFLP for three polychaete sibling species of the genus Marenzelleria, and the species’ current distribution in the Baltic Sea
There is an urgent need for a new genetic analysis of all Marenzelleria populations of the Baltic Sea to unravel the current distribution of the three species, and a newly developed PCR/RFLP protocol is recommended for large-scale analyses. Expand
Multiple Invasions – A Polychaete Genus Enters the Baltic Sea
Using three gene segments of the mitochondrial DNA, mitochondrial markers allow the exact identification of all Marenzelleria species and must be used whenever a classical taxonomic identification is uncertain, and demonstrate the applicability of the markers to discriminate the species with certainty.

A new molecular phylogenetic hypothesis for the evolution of freshwater eels.
Phylogenetic analysis of a segment of the mitochondrial 16S rDNA of eight Anguilla species from the Indo-Pacific region and from the North Atlantic revealed that the genus Anguilla appears to beExpand
Genetic differentiation in Hediste diversicolor (Polychaeta: Nereididae) for the North Sea and the Baltic Sea
There appear to be two different genetic types which are parapatric or sympatric in some places in Hediste diversicolor populations, regardless of whether found in the North Sea or Baltic Sea. Expand
Mutational analysis of the N-ras,p53,p16INK4a ,CDK4, and MC1R genes in human congenital melanocytic naevi
The activatedN-ras oncogene, which is also found in human cutaneous melanomas, may constitute a potential risk factor for melanoma formation within CMN. Expand
Mitochondria-rich (MR) cells and the activities of the Na+K+-ATPase and carbonic anhydrase in the gill and opercular epithelium of Oreochromis mossambicus adapted to various salinities
In the gill all parameters examined increased significantly in correlation to an enhanced environmental salinity, whereas in the opercular epithelium the activities of the enzymes remained constant. Expand

It is likely, that functional constraints play an important role in the evolutionary dynamics and extant appearance of the repeat array, and it will bring forward the understanding of mitogenome evolution within the Peracarida, for which much more derived gene orders are known. Expand
Two cryptic species of the Hediste diversicolor group (Polychaeta, Nereididae) in the Baltic Sea, with mitochondrial signatures of different population histories
A presence of two cryptic biological species of Hediste diversicolor complex polychaetes was corroborated in a geographical survey of some 30 populations from the eastern and southern coasts of theExpand
A mitochondrial multigene approach contributing to the systematics of the brook and river lampreys and the phylogenetic position of Eudontomyzon mariae
The utility of 11 mitochondrial gene segments is examined to discriminate the closely related members of the European species pair Lamp- etra fluviatilis and Lampetra planeri to identify fast-evolving genes in the mtDNA that might allow a dis- crimination of pair members. Expand
