  abstract = {{I}n the state of {T}abasco, {S}outh-eastern, {M}exico, land-use changes such as the conversion of natural into agricultural systems, modify soil quality and the abundance of soil macrofauna, including earthworms. {T}he aim of this study was to characterize by near-infrared spectroscopy ({NIRS}) the earthworms' fingerprint in soil, in six sites including natural and agricultural ecosystems with low and high earthworm biomass and low and high earthworm diversity, in order to identify specific wavelengths that discriminate the presence/abundance of earthworm species and functional groups. {T}he spectral region of 1860-1870 nm was significantly correlated with total earthworm density, particularly at one of the sites ({C}edar polyculture; r=0.8, p < 0.05). {E}arthworm biomass had a specific {NIRS} wavelength according to the earthworm species and feeding category: 1820 and 1860-1870 nm wavelengths were significantly correlated with {P}olypheretima elongata (r(2) = 0.7, p <0.05; mesohumic species) biomass and 2090 nm for biomass of all {L}avellodrilus species (polyhumics). {T}wo species had a much wider spectral range: {L} bonampakensis and {D}ichogaster saliens (an epigeic worm; 1690-2300 nm, r(2) = 0.7, p <0.05). {B}iomasses of {P}eriscolex brachysistis and {D}iplotrema murchiei were not significantly correlated with any near infrared wavelength spectra analyzed. {C}ombining a maximum of 4 species per wavelength, mesohumic earthworms had a wider wavelength spectrum than polyhumics. {T}herefore, earthworm species diversity, biomass and abundance are associated with soil quality (as measured by {NIR} spectra) and this relationship varies with species and ecological category. {S}ites with lower and higher earthworm diversity have lower and higher soil organic matter quality, respectively, as observed by the wider or narrower spectral range with which earthworm biomasses are correlated.},
