  abstract = {{I}nteractions of earthworm species with their environment and in particular the soil they inhabit is poorly understood. {I}n this study, we aimed to use mid infrared absorption ({MIR}) spectroscopy of earthworm bodies in combination with discriminant analysis of principal components ({DAPC}), in order to investigate if their biogeochemical composition is determined by their species belonging or the soil they inhabit. {O}ur conceptual approach included the comparison of {MIR} spectra of four earthworm species ({L}umbricus terrestris, {A}llolobophora chlorotica, {A}porrectodea caliginosa and {A}porrectodea icterica) sampled from four different agricultural fields in {F}rance. {M}oreover, we tested the influence of the habitat on the earthworm {MIR} spectra by exchanging individuals and soils in an incubation experiment. {MIR} spectra varied according to species and sampling site. {T}he {MIR} spectra of earthworm bodies also changed during the incubation experiment, and for {L}. terrestris, {A}. chlorotica and {A}. icterica depended on the properties of the soil ingested. {T}his suggested that the food source in different habitats impacted the biogeochemical composition of earthworm bodies. {DAPC} allowed for the identification of earthworm species ranging from 64 to 100% of accuracy (mean 78%). {W}e thus conclude that {MIR} spectroscopy may be a suitable approach to identify earthworm species, but that their signature may also allow to investigate their ecology as determined by the soil they inhabit.},
