Climate change will affect biotic and abiotic soil ecosystem components and therefore ecosystem services. This situation may worsen in metal-contaminated soils where organisms have to deal with multiple stress factors and metal toxicity may change depending on climate conditions. Most research has focused on how single climate factors (temperature, soil moisture) may affect the toxicity of single metals, using soil invertebrates as bioindicators. However, less attention has been paid to the effects of CO2 levels, UV radiation and the combination of multiple climate factors. Moreover, most research has used reference or artificial soils instead of field-contaminated soils. The project METOXCLIM aims to assess how biotic and abiotic components of metal-contaminated soils may be affected under the current global warming perspective, by using toxicity (measured by means of soil invertebrates) and the associated changes in functional soil parameters (chemical, physicochemical, microbiological) as indicators of ecosystem services. The specific objectives are: 1) assessing the sensitivity of different soil parameters (chemical, physicochemical, microbiological) to changes induced by single climate factors (air temperature, soil moisture content, atmospheric CO2 concentrations, UV radiation) in metal-contaminated soils; 2) assessing the sensitivity of different soil invertebrate species to toxicity changes induced by single climate factors (air temperature, soil moisture content, atmospheric CO2 concentrations, UV radiation) in metal-contaminated soils; 3) assessing how the toxicity of metal-contaminated soils may be affected under different climate change scenarios, simulated by climate factor combinations (air temperature, soil moisture content, atmospheric CO2 concentrations, UV radiation), using soil invertebrates as bioindicators, and its relation to changes in functional soil chemical, physicochemical and microbiological parameters. Climate factor combinations will be based on the emission scenarios predicted by the IPCC by 2100. METOXCLIM will improve the capacity to predict the consequences of global warming in human-degraded soils, which, in turn, will enable a better preservation and sustainability of soil ecosystem services.
