Osteology and arthrology of the ankle and tarsometatarsus of anoles (Iguania: Anolidae): not convergent with geckos but divergent from the ancestral iguanian condition

Journal of Anatomy, EarlyView.
Geckos and anoline iguanid lizards are well‐known for their possession of adhesive toepads, which are generally regarded as being convergent structures. We show that the anatomical configuration of the foot in these two lineages differs markedly and that these differences likely relate to the contrasing ways they deploy their adhesive systems and ...

The hearing capabilities of the Dromornithidae (Aves), with inferences on acoustic communication and ecology

Journal of Anatomy, EarlyView.
The preservation of bony structures which enclose the hearing organs (ECD) provide a basis for interpreting the hearing capabilities of the extinct, flightless Dromornithidae (Aves). Although the length of the dromornithid ECD was especially short, relative to basicranial length, it conformed to the negative allometric scaling relationships observed in

Investigation of otolith responses using ground based vestibular research facility [PDF]

The general goal was to examine tilt sensitivity of horizontal semicircular canal afferents. Computer programs were tested which controlled the short axis centrifuge at the Vestibular Research Facility, acquired action potentials and produced data ...

Morphometric study of the bony labyrinth of the inner ear in the European moles Talpa europaea, Talpa occidentalis, and Talpa aquitania

Journal of Anatomy, EarlyView.
The study investigates the shape of the semicircular canals in the inner ear of three sister mole species—Talpa europaea, Talpa aquitania, and Talpa occidentalis—using geometric morphometrics on 58 specimens. It finds both interspecific and intraspecific variability in canal morphology, but no evidence of sexual dimorphism.

Ossification of the cranium of Inpaichthys kerri (Characiformes: Acestrorhamphidae) with discussion of paedomorphic traits in the genus

Journal of Anatomy, EarlyView.
In this study, we present a detailed description of the cranial development of Inpaichthys kerri (Characiformes: Acestrorhamphidae), highlighting important topics such as pedomorphic characters and their relationship with ontogeny and phylogeny, as well as ossification sequences unique to the species. Abstract The study of development provides valuable
