Eudrilus eugeniae, also called the "African nightcrawler", is an earthworm species native to tropical west Africa and now widespread in warm regions under vermicompost; it is an excellent source of protein and has great pharmaceutical potential. [1] [2]
Eisenia fetida, known under various common names such as manure worm, [2] redworm, brandling worm, panfish worm, trout worm, tiger worm, red wiggler worm, etc., is a species of earthworm adapted to decaying organic material. These worms thrive in rotting vegetation, compost, and manure. They are epigean, rarely found in soil.
The worms' digestive systems create environments that allow certain species of microbes to thrive to help create a "living" soil environment for plants. [9] The fraction of soil which has gone through the digestive tract of earthworms is called the drilosphere. [10] Vermicomposting is a common practice in permaculture. [11] [12]
Megascolecidae is a family of earthworms native to Madagascar, Australia, New Zealand, Asia, and North America. [2] At up to 2 meters in length, [ 3 ] their large size distinguishes the Megascolecidae from other earthworm families.
Exploring earthworm behaviour and ecology, it continued the theme common throughout his work that gradual changes over long periods of time can lead to large and sometimes surprising consequences. It was the first significant work on soil bioturbation , although that term was not used by Darwin (it first appeared in the soil and geomorphic ...
The design parameters of vermifilters include stocking density of earthworms [17] (although over time earthworm population tends to be self-moderating), filter media composition, [18] hydraulic loading rate, [19] hydraulic retention time [13] [20] and organic loading rate. Hydraulic retention time and hydraulic loading rate both affect effluent ...
Vermifilter toilet, also known as a primary vermifilter, vermidigester toilet, tiger toilet [1] [2] or tiger worm toilet, [3] is an on-site sanitation system in which human excreta are delivered from a toilet (usually by flushing) onto a medium containing a worm-based ecosystem.
However, 'earthworm' can be a source of confusion since, in most of the world, other species are more typical. For example, through much of the unirrigated temperate areas of the world, the "common earthworm" is actually Aporrectodea (= Allolobophora ) trapezoides , which in those areas is a similar size and dark colour to L. terrestris .
