    Ecomorphological differences between sister species, Rhinolophus capensis and Rhinolophus swinnyi
    (2008) Kelly, Elizabeth Jane; Jacobs, David S
    Phenotypic analyses of sibling species provide the opportunity to examine divergence that is caused by adaptation rather than phylogenetic history. Rhinolophus capensis and Rhinolophus swinnyi diverged from a common ancestor between 15 and 20 million years ago. The Fynbos biome of the south-western Cape (South Africa) arose around the same time, and its distribution is coincident with that of R. capensis. Since this event probably influenced the speciation of these species, I examine differences in the ecomorphology of these bats in their current distributions. R. capensis is bigger than R. swinnyi, with corresponding differences in echolocation call signatures and wing morphology.
