The development of the genital ducts in Limnodriloidinae (Tubificidae, Clitellata)

Journal of Zoology, 2002
AbstractThe development of the male duct and spermatheca is studied in three species of the marine Limnodriloidinae (Tubificidae): Limnodriloides rubicundus; Tectidrilus bori; Thalassodrilides ineri. All tubificids are hermaphroditic with paired male ducts, female ducts and, as a rule, spermathecae.

Ecology of Tidal Freshwater and Estuarine Tubificidae (Oligochaeta)

1980
There is an abrupt shift in the community composition of Tubificidae as one proceeds from tidal freshwater to estuarine habitats. Not only does the species composition change but also their relative trophic importance and, to a more variable degree, their importance to the community. Communities from tidal freshwater areas tend to resemble the fauna of

Life-cycle and karyology of Branchiura sowerbyi Beddard (Oligochaeta, Tubificidae)

Hydrobiologia, 1984
Data on the life-cycle of a population of Branchiura sowerbyi Beddard in a water-lily tank at the Botanical Garden in Padua are reported. The breeding period is from April to July, after which the reproductive system is partially resorbed (August-September) and reformed later in the autumn. The karyology of the species was also studied, and revealed 38

Biology of Limnodrilus claparedeanus Ratzel (Oligochaeta, Tubificidae) in the Tsimlyansk Reservoir

Hydrobiologia, 1994
Limnodrilus claparedeanus with its high productivity is the most numerous tubificid species in the Tsimlyansk Reservoir. As a result of frequent reproduction, young worms are abundant in the population. Individuals mature in a short time and are able to lay cocoons nine weeks after hatching.

Life Cycles of Mass Species of Tubificidae (Oligochaeta)

1980
The life cycles of mass species of Tubificidae: Isochaetides newaensis, Tubifex tubifex and Limnodrilus hoffmeisteri have been studied in rivers, reservoirs, lakes and under experimental conditions. The length of the life cycles depend on abiotic and biotic factors of the environment.
