Earthworm diversity and ecosystem services in agriculture: Choosing appropriate taxon indicators and measurements

Abstract: Agriculture and biodiversity are strongly linked. Whilst agriculture is a main driver impacting biodiversity, farmers could benefit from ecosystem services linked to biodiversity. Hence, indicators of functional biodiversity are needed. However, finding correct indicator values is not trivial. Earthworms were sampled on nine German farms with a combined method. In total 3205 earthworms from 10 species were collected. Six measurements applicable as taxon indicators were calculated for the data.

Today, the attention of many researchers is turned to nanoparticles (NPs) and their use in practice. At the same time, nanoforms can exhibit toxic effects in relation to living organisms. One of the promising models for assessing the effect of nanoparticles is the E. fetida worm. In this regard, the aim of our study was to study the responses of the E. fetida worm in artificial soil with the introduction of NPs of Cu and CuO. In our work, we evaluated mortality, the mass of worms, the activity of antioxidant enzymes, and the content of malondialdehyde in the worm when introducing NPs of Cu and CuO at a concentration of 0; 50; 100 and 500 mg/kg of dry soil. In the course of our study, we found the stimulating effect of the minimum of the studied dosages of CuO NPs (50 mg / kg), which in the future may be of an applied nature. It has been established that Cu NPs have the highest toxicity, causing high mortality rates (80 %), a 50 % weight reduction (p ≤ 0.05) at a dosage of 500 mg/kg against the background of increased catalase activity and malondialdehyde content with a decrease in superoxide dismutase activity.
