Climate change causes species range shifts and potentially alters biological invasions. The invasion of European earthworm species across northern North America has severe impacts on native ecosystems. Given the long and cold winters in that region that to date supposedly have slowed earthworm invasion, future warming is hypothesized to accelerate earthworm invasions into yet non-invaded region...

Atrazine and metolachlor were more strongly retained on earthworm (Lumbricus terrestris L.) castings than on soil, suggesting that earthworm castings at the surface or at depth can reduce herbicide movement in soil. Herbicide sorption by castings was related to the food source available to the earthworms. Both atrazine and metolachlor sorption increased with increasing organic carbon (C) conten...

A series of nine 2-arylidene-4-(4methoxy/phenoxy-phenyl)but-3-en-4-olides (I-IX) were screened against Pheretima posthuma earthworm species to assess the anthelmintic activity of the synthetic derivatives. The in vitro effects of compounds were evaluated at a concentration of 2mg/mL and time taken by the derivatives to paralyze and subsequently kill the worms was recorded. Synthetic butenolide ...

• Earthworm remove PAHs from soil by bioaccumulation and stimulating microbial degradation. Biochar can adsorb promote degradation in soil. improve the adsorption process of biochar bioturbation. reduce vermiaccumulation decomposition earthworm. Polycyclic aromatic hydrocarbons (PAHs) pose a threat to health humans other organisms due their persistence. The remediation method combined applicati...

The Pheretima complex within the Megascolecidae family is a major earthworm group. Recently, the systematic status of the Pheretima complex based on morphology was challenged by molecular studies. In this study, we carry out the first comparative mitogenomic study in oligochaetes. The mitogenomes of 15 earthworm species were sequenced and compared with other 9 available earthworm mitogenomes, w...

The gut of many soil arthropods contains a complex and mutualistic microbial community that usually assists the host with digestion. The same is probably true for earthworms, but the nature and function of the microbiota inhabiting their gut are virtually unknown. In this paper, we studied the microbial community in the gut content of the earthworm Lumbricus terrestris L. and in the bulk soil b...

BACKGROUND Recent studies suggested that the earthworm Lumbricus terrestris might act as a seedling predator by ingesting emerging seedlings, and individuals were observed damaging fresh leaves of various plant species in the field. To evaluate the significance of herbivore behavior of L. terrestris for plant and earthworm performance we exposed 23- to 33-days-old seedlings of six plant species...

The mechanism associated with improvement of soil nutritional status by oilseed rape crop, leading to better performance of rice crop, in rice-oilseed rape cropping systems is little known. The present study was aimed to test the hypothesis that earthworm casts produced during oilseed rape-growing season have positive effects on grain yield and fertilizer nitrogen (N) utilization in the subsequ...

The effects of earthworm inoculation and cropping systems on upland rice were examined over a four-year period in the Highlands Madagascar. Each year, endogeic earthworms Pontoscolex corethrurus (Rhinodrilidae) inoculated (EW+) at density 75 ind m?2 or not (EW0). Inoculation was tested three systems: conservation agriculture (CA) traditional tillage with without residues restitution. Soil plant...

Non-native earthworms have invaded ecosystems around the world but have recently received increased attention as they invaded previously earthworm-free habitats in northern North America. Earthworms can affect plants by ingesting seeds and burying them in the soil. These effects can be negative or positive but are expected to become increasingly negative with decreasing seed size. Orchids have ...
