The Effects of Earthworms on Fungal Diversity and Community Structure in Farmland Soil With Returned Straw

Frontiers in Microbiology, 2020
BackgroundTo promote the decomposition of returned straw, reduce the incidence of soil-borne diseases caused by returned straw, and accelerate the conversion of straw carbon into soil carbon, we inoculated earthworms into fields with returned straw.

Effects of multi-walled carbon nanotubes in soil on earthworm growth and reproduction, enzymatic activities, and metabolomics

Ecotoxicology and Environmental Safety, 2022
Increased production and environmental release of multi-walled carbon nanotubes (MWCNTs) increase soil exposure and potential risk to earthworms. However, MWCNT toxicity to earthworms remains unclear, with some studies identifying negative effects and ...

Bioassays with terrestrial and aquatic species as monitoring tools of hydrocarbon degradation [PDF]

, 2016
In this study chemical analyses and ecotoxicity tests were applied for the assessment of a heavily hydrocarbon-contaminated soil prior and after the application of a remediation procedure that consisted in the stimulation of soil autochthonous ...

Ecotoxicological effects of a synthetic and a natural insecticide on earthworms and soil bacterial community

Environmental Advances, 2022
Earthworms and microbial communities are essential non-target soil organisms that are useful to assess the collateral impact of pesticides. The present paper reports three laboratory experiments performed to investigate the effects of sub-lethal doses of

The complete mitochondrial genome sequences of Japanese earthworms Metaphire hilgendorfi and Amynthas yunoshimensis (Clitellata: Megascolecidae)

Mitochondrial DNA. Part B. Resources, 2021
Many studies have reported the complete mitochondrial genome sequences of Chinese Megascolecidae earthworms, however, there have been no reports on sequences originating from Japanese Megascolecidae earthworms.

Asymmetrical hybridization and gene flow between Eisenia andrei and E. fetida lumbricid earthworms [PDF]

, 2018
Uniformly pigmented Eisenia andrei (Ea) and striped E. fetida (Ef) lumbricid earthworms are hermaphrodites capable of self-fertilization, cross-fertilization, and asymmetrical hybridization.

Soil biological quality of grassland fertilized with adjusted cattle manure slurries in comparison with organic and inorganic fertilizers [PDF]

, 2009
We studied the effect of five fertilizers (including two adjusted manure slurries) and an untreated control on soil biota and explored the effect on the ecosystem services they provided.

Soil heterogeneity and earthworms independently promote growth of two bamboo species

Ecological Indicators, 2021
Soils are commonly spatially heterogeneous and earthworms are widely distributed in terrestrial ecosystems. While both soil heterogeneity and earthworms can influence the performance of plants, whether they can interact to affect the growth of bamboo ...

Earthworm-mycorrhiza interactions can affect the diversity, structure and functioning of establishing model grassland communities.

PLoS ONE, 2011
Both earthworms and arbuscular mycorrhizal fungi (AMF) are important ecosystem engineers co-occurring in temperate grasslands. However, their combined impacts during grassland establishment are poorly understood and have never been studied. We used large
