Hyperspectral data as a biodiversity screening tool can differentiate among diverse Neotropical fishes

Abstract Hyperspectral data encode information from electromagnetic radiation (i.e., color) of any object in the form of a spectral signature; these data can then be used to distinguish among materials or even map whole landscapes. Although hyperspectral data have been mostly used to study landscape...
