Understanding global biodiversity change, its drivers, and the ecosystem consequences requires a better appreciation of both the factors that shape soil macrofauna communities and the ecosystem effects of these organisms. The project "sOilFauna" was funded by the synthesis center sDiv (Germany) to address this major gap by forming a community of so...

Soil-exchangeable aluminum (Al) has toxic effects on living organisms in acidic soils. Earthworm presence and activity can alter soil pH, which has a significant influence on Al toxicity. However, the effects of earthworms on soil Al toxicity and fractions are still largely unknown. This laboratory study focused on the effects of three earthworm sp...

Herb residue vermicompost is thought to have high agriculture value, while its effects on soil microbial activities have not been fully understood. Here, soil microbial biomass, respiration and enzyme activities in soil planted with maize were compared among treatments amended with herb residue vermicompost at rates of 25, 50, 75 and 100 g kg−1, ch...

The study aims to investigate effect of earthworm activity on metal bioavailability in soils using their BSAF-metals. Based on a microcosmic laboratory experiment, epigeic species Amynthas corticis (A. corticis) and endogeic species Amynthas robustus (A. robustus) were cultured in two types of soils contaminated by Cd, Zn, Pb and Cu for 120 days. E...

Microbial attributes have a great impact on soil heavy metal bioavailability, yet their influencing pathway on heavy metal accumulation in crop plants remains elusive. This study was aimed to analyze the influencing pathways of microbial attributes, including microbial biomass C and N (MBC and MBN), basal soil respiration (BSR) along with the activ...
Article
The effects of the native species Amynthas morrisi and the composting earthworm Eisenia fetida were evaluated on the forms of Zn, Cd, Pb and Cu in a long-term contaminated Chinese soil, with and without added organic matter (OM), in a 60-day laboratory experiment (25 °C field capacity). Four metal fractions were extracted using a sequential procedu...

We tested the effect of an addition of organic matter (OM: 10% of a mixture of coconut bran and cattle dung) and/or earthworm inoculation (15g fresh weight kg-1 soil) in a soil polluted by metals on microbial activities and concentrations of metal DTPA extractable fractions. The experiment, conducted under laboratory conditions, lasted for 60days....

Two earthworm species (Eisenia foetida and Amynthas morrisi) were inoculated in dryland and paddy soil mixed with 15% paper mill sludge for 30 days. Effects of earthworm on soil chemical and biological properties were evaluated, which included pH and Eh value, contents of organic carbon and dissolved organic carbon, contents of total nitrogen, phos...

Taking the lateritic red soil on a typical slopeland in Southern China as test object, this paper studied the soil microbial properties, enzyme activities, and their relationships with soil fertility under four land use types (newly cultivated dryland, shrub land, Eucalyptus land, and orchard). There existed significant differences in the soil biol...

A pot experiment was conducted to evaluate the effects of herb residue vermicompost on maize growth and soil fertility. With the increasing application rate of vermicompost, the plant height, stem diameter, leaf area, and chlorophyll content of maize all increased significantly. After 60 days growth of maize, the soil bulk density in most vermicomp...

(1) to learn the ecotoxicological effects of N-HAP on earthworms when it is used at different doses for long-term remediation of Cd-contaminated soils; and (2) to reveal the biochemical mechanism of how earthworms affect Cd accumulation in maize during Cd-contaminated soil remediation using N-HAP as a stabilizer
Project
Goal: to conduct a global synthesis of the available data on soil macrofauna abundance. Soil macrofauna are invertebrates that live in soil or in the litter, with a body size larger than 1-2 mm. Typical examples are ants, earthworms, spiders and myriapods. A few topics we wish to explore: - How climate and Land Use affect soil macrofauna communities? - Are abundance and diversity of these animal following the classical latitunidal gradient? - How land management and agricultural practices affect soil macrofauna communities, and how is it linked to crop productivity and soil security? - Can we build bioindicators of soil fertility and agricultural practices based on soil macrofauna data?
