One significant biotic interaction of Lumbricus rubellus results from a relationship with vitamin B 12-producing microorganisms such as bacteria and actinomycetes and barley. [3] The presence of such earthworms as Lumbricus rubellus increases concentrations of vitamin B 12-producing microorganisms and vitamin B 12 in the soil. The result is an ...
Lumbricus terrestris is a large, reddish worm species thought to be native to Western Europe, now widely distributed around the world (along with several other lumbricids). In some areas where it is an introduced species , some people consider it to be a significant pest for out-competing native worms.
The Lumbricidae are a family of earthworms.About 33 lumbricid species have become naturalized around the world, [1] but the bulk of the species are in the Holarctic region: from Canada (e.g. Bimastos lawrenceae on Vancouver Island) and the United States (e.g. Eisenoides carolinensis, Eisenoides lonnbergi and most Bimastos spp.) and throughout Eurasia to Japan (e.g. Eisenia japonica, E. koreana ...
Lumbricus herculeus and Lumbricus terrestris, widely spread invasive earthworms native to Europe. Invasive species of earthworms from the suborder Lumbricina have been expanding their range in North America. [1] Earthworms are considered one of the most abundant macroinvertebrates in the soil of ecosystems in temperate and tropical climates. [2]

A. lumbricoides was originally called Lumbricus teres and was first described in detail by Edward Tyson in 1683.
