Retinal Spectral Sensitivity, Fur Coloration, and Urine Reflectance in the Genus Octodon (Rodentia): Implications for Visual Ecology

Purpose: To determine the eye’s spectral sensitivity in three species of the genus Octodon (order Rodentia; infraorder Caviomorpha), O. degus, O. bridgesi, and O. lunatus, as well as the spectral properties of the animals’ fur and urine and of objects in their habitat. The genus is endemic in Chile and contains species with different habitats […]
