The earthworm, which has stasis removal and wound-healing functions, is a widely used Chinese herbal medicine in China. Schwann cell migration is critical for the regeneration of injured nerves. Schwann cells provide an essentially supportive activity for neuron regeneration. However, the molecular migration mechanisms induced by earthworms in Schwann cells remain unclear. Here, we investigate ...

1. The effects of the anecic earthworm Lumbricus terrestris L. on plant seedling recruitment and spatial aggregation were investigated in a microcosm glasshouse experiment by varying plant seed size (small and large); functional groups (grasses, legumes, herbs); plant species diversity (1, 3, 6); and plant functional group diversity (1, 3). 2. Generally, earthworms buried seeds quickly irrespec...

Huge amounts of coal fly ash (FA), produced during power generation, has led to several environmental problems associated with metal pollution and the burden of its disposal. Vermicomposting has emerged as a cost-effective technique in suitable management of FA. Two epigeic earthworm species: Eisenia fetida, and Eudrilus eugeniae and one epi-endogeic species: Lumbricus rubellus were selected fo...

Physical changes caused by forest management practices can have a dramatic effect on the soil biota in a forest ecosystem. The effects of soil compaction associated with harvesting on earthworm populations and selected soil properties were measured in a hardwood (oak-hickory) forest in Missouri. Soils in this region of Missouri are characterized by a cherty residuum that is primarily of the Cla...

The activity and spread of exotic earthworms often are spatially correlated with N deposition because both arise from human activities. Exotic earthworms, in turn, can also greatly affect soil abiotic and biotic properties, as well as related ecological processes. Previous studies showed, for example, that earthworms can counteract the detrimental effects of plant-feeding nematodes on plant gro...

We used filter paper contact test method for obtaining LC50 for cythion and dieldrin. This Organophosphate is very poisonous, which affects the body and Growth of Earthworm. We had seen in the test solution of 0.8mg/cm, 0.9m g/cm and 1mg/cmof 1% dieldrin, all earthworms died and melt. Similarly, cythion 0.3 and 0.27 showed the same result. This concentration was shown supertoxic to earthworms. ...

Earthworms are globally distributed and perform essential roles for soil health and microbial structure. We have investigated the effect of an anthropogenic contamination gradient on the bacterial community of the keystone ecological species Lumbricus rubellus through utilizing 16S rRNA pyrosequencing for the first time to establish the microbiome of the host and surrounding soil. The earthworm...

BACKGROUND The distribution pattern of the earthworm gut microbiota at the host population level is of fundamental importance to understand host-microbiota interactions. Our current understanding of these interactions is very limited. Since feeding represents a main perturbation of the gut microbiota, we determined the effect of a single dose of feed on the microbiota associated with an earthwo...

Microorganisms are well adapted to their soil microhabitat where they live together in consortia, interacting with other living members, including earthworms. This literature review consists of four sections that focus on microscale interactions between earthworms and microorganisms. The first part is devoted to nephridia symbiosis. Recent discoveries show that Verminephrobacter spp. is present...

Earthworms possess antioxidant, antibacterial, antitumor, and hemolytic properties. To recognize the molecules responsible for various biological activities of earthworm’s coelomic fluid, a detailed knowledge about its protein contents is required. The aim of this study was to characterize the proteins present within the coelomic fluid of Eisenia foetida earthworm. Polyacrylamide-gel-elec...
