Caption: A ring-tailed lemur scent-marks a tree at the Duke Lemur Center. Olfactory signals and sounds from female lemurs can throw members of their group into a tizzy. But not all combinations of noises and odors evoke the same response. Ring-tailed lemurs respond more strongly when the scent they smell matches the voice they hear.
