Fast attrition of springtail communities by experimental drought and richness-decomposition relationships across Europe.

摘要: Soil fauna play a fundamental role on key ecosystem functions like organic matter decomposition, although how local assemblages are responding to climate change and whether these changes may have consequences functioning is less clear. Previous studies revealed that continued environmental stress result in poorer communities by filtering out the most sensitive species. However, experiments rarely been applied factors combining multiyear multisite standardized field treatments across climatically contrasting regions, which has limited drawing general conclusions. Moreover, other facets of biodiversity, such as functional phylogenetic diversity, potentially more closely linked functioning, largely neglected. Here, we report abundance, species richness, richness springtails (Subclass Collembola), major group fungivores detritivores, decreased within 4 years experimental drought six European shrublands. The loss was higher than expected leading phylogenetically similar sharing evolutionary conserved traits. Additionally, despite great climatic differences among study sites, found taxonomic, phylogenetic, springtail alone were able explain up 30% variation annual decomposition rates. Altogether, our results suggest forecasted reductions precipitation associated with erode likely drought‐sensitive soil invertebrates, thereby retarding litter nutrient cycling ecosystems.
