morphology of the external nose in hipposideros diadema and lavia frons with comments on its diversity and evolution among leaf-nosed microchiroptera. | in some bats, a noseleaf is thought to help focus echolocation calls emitted through the nostrils. i studied the ontogenetic mode of the rhinarial cartilages and the associated facial muscles to assess how these rhinarial infrastructures interact with the noseleaf, and the inferred function of such a rhinarial complex. this study focuses on developmental stages of hipposideros diadema and lavia frons. based on new data on these two rhinolophoids and a review of former studies concerning rhinopom ... | 2002 | 11602802 |
