A fascinating new study in the Zoological Journal of the Linnean Society co-authored by Yale anthropologist Eric Sargis finds that the barking hyraxes are a seperate species from their shrieking neighbors. The Newly described species Dendrohyrax interfluvialis, populates the wet and dry forests that lie in between the two rivers in coastal regions of southeastern Ghana, southern Togo and Benin, and southwestern Nigeria. The researchers based their conclusion on the distinctive calls combined with anatomical and genetic differences they identified among tree hyrax populations.
