Genetic diversity of the Aporrectodea caliginosa complex in Russia
Earthworms of the Aporrectodea caliginosa species complex are abundant in many anthropogenic and natural habitats and often predominate in earthworm communities. In Russia, there are two subspecies of the complex, A. c. caliginosa and A. c. trapezoides; Aporrectodea longa was also recently mentioned...
