[Caudal regeneration in Nicodrilus giardi (Ribaucourt) (Oligocheta, Lumbricidae): worms amputated at the end of summer diapause].
N. giardi collected at the end of the summer diapause were amputated at two levels of the posterior part of the body: After amputation of the 100 posterior segments (nearly half the body), the regeneration processes appear quickly. An amputation removing only the 30 posterior segments is followed by a reorganization in the injured area, but the worms are incapable of regeneration.
