Effect of urine, faeces, blood and pig meat on soil micro-Eukaryotes

Decomposing cadavers impact the soil ecosystem by massive inputs of nutrients producing a “cadaverdecomposition island (CDI)”. This pulse of resources affects the soil biota (diversity and community structure) and functions drastically; yet these effects are not well understood. Furthermore, even less is known about how these effects compare to those induced by other nutrient pulses from faeces, urine, and -­ especially relevant in a forensic context – blood. Resource pulses contribute to enhancing regional biodiversity through the contrasted responsesof different taxa and the spatial and temporal heterogeneities they generate. This aims to evaluate the change of micro-Eukaryote communities in response to faeces, urine, blood and pig meat, and compare this response to that generated by entire pig cadavers.
