Larger soil organisms have often been reported as the most sensitive to disturbances caused by cropping practices. However, macrofauna comprises groups with a wide diversity of morphological and ecological features, which may respond differently applied In order further assess effect systems on macrofauna, were extracted from blocks over 21 fields (each comprising three plots) located in Paris basin, autumns 2020 2021. Fields belonged conventional, conservation or organic systems, either long-established (≥ 7 years) transition (≤ 3 years). Tillage, pesticide treatment matter input intensity assessed each field using composite indexes practice intensity. Macrofauna density diversity, earthworm categories, species richness functional traits investigated. Our results showed that demonstrated few differences regarding different highly variable effects across years. Specific macroarthropod responded tillage, intensity, but not two years study. Regarding earthworms, high tillage had negative biomass epi-anecic juveniles small body size. Higher inputs endogeic could be related several (body length, mass/length ratio, carbon preferences). Effects treatments less clear, although they impacted some species. More generally, taxonomic trait approaches community led similar conclusions. Overall, our support need account for (i) actual practices (ii) taxonomic, trophic biodiversity.

Artificial Light at Night Reduces the Surface Activity of Earthworms, Increases the Growth of a Cover Crop and Reduces Water Leaching

Artificial light at night (ALAN), also known as pollution, is a growing environmental problem worldwide. However, only few studies have examined whether soil organisms that search for food the surface can be affected by ALAN. We investigated effects of ALAN on above-ground foraging activity anecic earthworms (Lumbricus terrestris), water infiltration and germination growth cover crop (Phacelia tanacetifolia). In full-factorial greenhouse experiment, we tested four factors: (about 5 lx during vs. total darkness), (two specimens none), plant species alone mixed with ragweed Ambrosia artemisiifolia) sowing depth (surface-sown sown in cm depth). Data were analysed using multifactorial ANOVAs. Earthworms removed 51% less litter under than dark conditions. had no effect Phacelia but resulted increased height biomass production when seeds buried. reduced production. leaching through experimental units, probably due to interactions between subsurface casts roots. conclude ALAN, emitted from streetlights, lead complex ecological ecosystems merit further investigation.
