[Intraspecific genetic and morphological variation of earthworm Eisenia foetida (Sav.)].
Polyacrylamide gel electrophoresis was used to study the allelic frequency distribution of four polymorphic loci (Pox, Lap, Pgm, and Odh) in 22 samples of Eisenia foetida (Sav.) from distant parts of the range: European Russia, Ukraine, Kazakhstan, and Kyrgyzstan. A hierarchical population structure was demonstrated for this species: local populations are integrated into spatial groups. Statistical analysis of morphological variation demonstrated that recognition of the spatial groups on the basis of biochemical and genetic characters as individual taxa of any rank is not justified.
