Close up of an earthworm in garden soil. Earthworms travel underground by means of waves of muscular contractions which alternately shorten and lengthen the body (peristalsis). The shortened part is anchored to the surrounding soil by tiny clawlike bristles set along its segmented length. In all the body segments except the first, last and ...
It lives in semi-permanent burrows and can reside in or escape to deeper soil layers. [4] Its activity is limited by temperature and humidity. High soil and night air temperatures inhibit activity, as do low night moisture and dry soil. During such times, particularly in the summer, the worms will retreat to the deepest parts of their burrows.
They are also often the numerically dominant earthworm species in England, especially in neutral to base-rich grasslands and arable soils. [9] Because Allolobophora chlorotica is an endogeic worm, it builds complex lateral burrow systems through all layers of the upper mineral soil. This species of worm rarely comes to the surface, instead it ...

Soil. Improves soil aeration; Enriches soil with micro-organisms (adding enzymes such as phosphatase and cellulase) Microbial activity in worm castings is 10 to 20 times higher than in the soil and organic matter that the worm ingests [46] Attracts deep-burrowing earthworms already present in the soil; Improves water holding capacity [47] Plant ...
Earthworms are considered one of the most abundant macroinvertebrates in the soil of ecosystems in temperate and tropical climates. [2] There are around 3,000 species known worldwide. [2] They are considered keystone species in their native habitats of Asia and Europe because, as detritivores, they alter many different variables of their ...
