Conteúdo: |
Worldwide, six species of enchytraeids are considered to reproduce by fragmentation (architomy) and two are known from Southern Brazil: Enchytraeus dudichi Dózsa-Farkas, 1995 and Enchytraeus bigeminus Nielsen & Christensen, 1963. The former species was recently found in Campo Largo City, Paraná State, this being the first record from South America. We found that E. dudichi s.l. grows easily in tropical artificial soil, natural soil, and in agar medium. We succeeded in inducing fragmentation in worms subjected to decapitation and subsequent incubation on filter paper, but not on agar medium. Morphologically, the regeneration process is very similar to other fragmenting worms of the same genus. This is the first study on reproductive and regenerative biology of enchytraeids in Brazil, from where little information on this family is available. |
