Structure of the Lampetra Fluviatilis in the Russian Part of the Baltics
As a results enhanced value of the total body length and the number of trunk myomers were found, new dental formula was discovered.
It was revealed that L. fluviatilis and L. planeri are presented by different forms within Baltic part of the species’ range. These forms are the result of the implementation of various life history strategies in a complex network of lakes and rivers of the Baltic basin.
Using genetic, morphologic and statistical methods it is shown that the taxa considered earlier as different species within the genus Lampetra, are only parasitic and non-parasitic forms of single species Lampetra fluviatilis.
