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

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

Effects of earthworms and mycorrhizal fungi on the growth of the medicinal herb Calendula officinalis (Asteraceae)

open access: yesPlant, Soil and Environment, 2011
Both earthworms and symbiotic arbuscular mycorrhizal fungi (AMF) often co-occurr in ecosystems, however very little is known on their interrelationships.

Using deuterated PAH amendments to validate chemical extraction methods to predict PAH bioavailability in soils [PDF]

open access: yes, 2011
Validating chemical methods to predict bioavailable fractions of polycyclic aromatic hydrocarbons (PAHs) by comparison with accumulation bioassays is problematic.

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

open access: yesFrontiers 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.

Impacts of earthworms and their excreta on peat soil properties and bacterial community

open access: yesGlobal Ecology and Conservation, 2023
Peatlands store 20–30 % of the global soil carbon (C). Earthworms simultaneously increase net C stabilization and net C mineralization. But little is known about the impact of earthworm invasion on the C cycling in peat soils.

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

open access: yes, 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

open access: yesEnvironmental 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

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

open access: yesEcotoxicology 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 ...

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

open access: yes, 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.
