Cranial differences in three-toed jerboas (Dipodinae, Dipodidae, Rodentia) according to recent taxonomic revisions

ABSTRACT: Abstract Recent phylogenetic studies amended the taxonomy of three-toed jerboas (subfamily Dipodinae), including raising subspecies to full species. Here, we use geometric morphometrics to compare scaled-shape differences in dipodine crania while considering their revised taxonomy. We sampled Dipus deasyi, D. sagitta halli, D. s. sowerbyi, Jaculus blanfordi blanfordi, J. hirtipes, J. jaculus, J. loftusi, J. orientalis gerboa, J. o. mauritanicus, and Stylodipus andrewsi. Crania were not sexually dimorphic. Common allometry explained some of the shape variation, for example, reduced braincases in larger specimens. Most operational taxonomic unit pairs differed in both size and shape. Dipus and Stylodipus clustered together based on their cranial shape. Jaculus differed from the aforementione
