Warming shifts the biomass distribution of soil microarthropod communities

Climate warming is often more detrimental to large body sized organisms than small organisms. Yet, how such differential effects of at organismal levels affect aggregate community properties, as biomass, remains little understood. Here, using geothermally warmed sub-Arctic grassland soils, we investigate total biomass (product density and individual mass) two major groups soil microarthropods (Collembola mites), which are composed both species, shift in soils when by ∼3–∼6 °C. Our results show that Collembola significantly decreased predominantly due a decline the species. In contrast, mite showed unimodal response warming. As result, there was towards dominated microarthropod communities soils. Within Collembola, deep living eu-edaphic functional group declined most whereas mites pronounced oribatid mites. study highlights induced shifts likely greater on several Collembola.
