ICZN rules—a farewell to Tubificidae (Annelida, Clitellata)

Zootaxa, 2008
Morphological and molecular characters support that the former clitellate family Naididae Ehrenberg, 1828 is nested within another family, Tubificidae Vejdovský, 1876. To avoid paraphyly of the latter, it has been suggested that the two should be regarded as a single taxon.

Insight into the effect of Tubificidae on dynamic membrane reactor: Membrane fouling mitigation and Tubificidae-ASM3-dynamic membrane coupled model

Bioresource Technology
To gain insights into the effects of Tubificidae on dynamic membrane sequencing batch reactor (DMSBR), 4 identical DMSBRs were operated with different Tubificidae densities (i.e., 0, 1, 2, 3 g ww/L). Experimental results showed that Tubificidae had a minimal effect on carbon and nitrogen removal but varied effluent turbidity and sludge characteristics.

The use of Tubificidae in a biological early warning system

Environmental Pollution, 1999
Tubificidae are aquatic annelids which occur abundantly in organically polluted waters. The anterior end of their body is buried in the sediment, while the posterior end moves in the water. This posterior end is (partly) retracted in the sediment in the presence of defined concentrations of pollutants.

Influence of small river conditions on the abundance of Tubificidae

Hydrobiologia, 1994
Two small rivers, the Yerik and Nezhegolyok, were studied seasonally in 1979–1980. Increase in concentration of nitrogen and phosphorus compounds in the river water as well as proliferation of enterococci and enterobacilli favoured the abundance of Tubificidae while, at the same time, their numbers were reduced by chironomids and leeches.

Marine species of Ainudrilus and Heterodrilus (Oligochaeta: Tubificidae: Rhyacodrilinae) from Hainan Island in southern China

New Zealand Journal of Marine and Freshwater Research, 2003
Six species of Rhyacodrilinae (Oligochaeta: Tubificidae) are reported from intertidal and shallow water subtidal habitats around Hainan Island in southern China. Four species are new to science: Ainudrilus pauciseta n. sp., Heterodrilus chenianus n. sp.,

Phylogeny of Tubificidae (Annelida, Clitellata) based on mitochondrial and nuclear sequence data

Molecular Phylogenetics and Evolution, 2005
The tubificid clitellates are a common component in the freshwater bottom fauna and are also the most abundant oligochaete group in marine habitats.

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 ...
