Morphology Reproduction

First record of reproduction by fragmentation in the genus Marionina

(Oligochaeta: Enchytraeidae)

Pages 151-156 | Published online: 28 Feb 2013
 

Abstract

Hermaphrodite enchytraeids usually breed sexually, but a few species can also multiply asexually by fragmentation (architomy). These species can alternate sexual breeding with asexual breeding by fragmentation. In Hungary, a Marionina species was found in the botanical garden of University of Szeged in 209, which is also able to reproduce asexually by architomy. No mature specimens of this species have been found so far. Fragmentation was observed rarely in these individuals and a strategy comparable to other fragmenting species is not known.
