The arboreal environment is complex and irregular imposes significant constraints on the locomotor ability of vertebrates, resulting in morphological adaptations. Carnivorans are particular interest because they radiated several times independently into milieu, leading to convergence long bone anatomy. We investigated whether forelimb muscles show differences vs. terrestrial species tested for muscle architecture. To do so, we studied 17 carnivorans with different modes (arboreal...
Hoatzin nestling locomotion suggests that bird transitional forms may have used a larger locomotor repertory.
Vertebrate osteological collections provide comparative material for morphological analysis. Before being stored in the collection and studied by researchers, specimens are treated preparators or curators cleaned. The preparation protocol employed ideally should not damage material. Here, we explore potential deformation of bones due to using geometric morphometric methods. We focus both on intraspecific interspecific variability. Our data scapular girdle birds show that, at an level, effect...
