Cuticular ultrastructure in some marine oligochaetes (Tubificidae)

Invertebrate Biology, 2000
Abstract. The ultrastructure of the thin, non‐cellular cuticle is described for 6 marine oligochaetes, representing 3 of the subfamilies (Phallodrilinae, Limnodriloidinae, and Rhyacodrilinae) of the Tubificidae. The main components of the cuticle in these 6 species, as in most other oligochaetes examined, are: (1) a fiber zone closest to the epidermis,

Mixed reproductive strategy in Tubifex tubifex (Oligochaeta, Tubificidae)?

Journal of Experimental Zoology Part A: Comparative Experimental Biology, 2005
AbstractDespite the wide use of the tubificid oligochaete Tubifex tubifex in eco‐toxicological studies, the reproductive strategy adopted by the species, that can reasonably be assumed to be the key to its ecological success, is still not well investigated.

Parthenogenesis in Tubificidae

Hydrobiologia, 1984
The ability of tubificids to reproduce parthenogenetically following or in place of bisexual reproduction has been proved. During parthenogenesis the spermatogenesis ceases at an early stage of sexual cell development, which, together with some peculiarities of the structure of the sexual system, rules out the possibility of self-fertilization in the ...

The double sperm line in Isochaetides (Annelida, Clitellata, Tubificidae)

Tissue and Cell, 2002
Sperm morphology and spermatogenesis were examined in the oligochaete annelid Isochaetides arenarius, a species belonging to the subfamily Tubificinae inhabiting the sediments of Lake Baikal. As all tubificines, Isochaetides produces two types of spermatozoa, named eusperm and parasperm.

Enzymatic variability in sympatric species of Tubifex (Clitellata: Tubificidae)

Hydrobiologia, 1999
The globally distributed species Tubifex tubifex Muller, 1774 (Clitellata; Tubificidae) is sometimes considered to include several different morphological forms, each recognizable by their chaetal structure. The ‘blanchardi’ form is a distinct species: sympatric populations of Tubifex tubifex and Tubifex blanchardi Vejdovsky, 1871 show complete ...

A morphological reappraisal of Tubifex blanchardi Vejdovský, 1891 (Clitellata: Tubificidae)

Acta Zoologica, 2009
Abstract Tubifex blanchardi Vejdovský, 1891 is a freshwater tubificid, often living in sympatry with Tubifex tubifex (Müller 1774). Although considered from its discovery as a species on its own, its biological status is debated. During the early seventies T. blanchardi was reduced to a mere form of T.
