ABSTRACT The vertebral column has evolved to accommodate the broad range of locomotor pressures found across vertebrate lineages. Xenarthran (armadillos, sloths and anteaters) vertebral columns are characterized by xenarthrous articulations, novel intervertebral articulations located in the posterior trunk that are hypothesized to stiffen the vertebral column to facilitate digging. To determine the degree to which xenarthrous articulations impact vertebral movement, we passively measured…

Size and shape regional differentiation during the development of the spine in the nine‐banded armadillo (Dasypus novemcinctus)

It is shown that posterior thoracic vertebrae grow at a slower rate, while anterior thoracics and lumbars grow atA faster rate relatively, with rates decreasing anteroposteriorly in the former and increasing antero‐operatively in the latter.

Size and shape regional differentiation during the development of the spine in the nine-banded armadillo (Dasypus novemcinctus)

It is proposed that different proportions between vertebrae and vertebral regions might result from differences in growth pattern and timing of ossification, which might in turn correlate with expression patterns of Hox genes.

The vertebral column of Chaetophractus villosus (Desmarest, 1804) (Chlamyphoridae, Cingulata, Xenarthra): anatomy and Thoracolumbar variation. Spinal cord relation

A comprehensive study of the vertebral column of Chaetophractus villosus, a representative of Chlamyphoridae, in order to provide a more reliable comparative framework among armadillos and to elucidate the patterns of distribution of this trait among xenarthrans.

AutoBend: An Automated Approach for Estimating Intervertebral Joint Function from Bone-Only Digital Models

This work describes and experimentally validate AutoBend, an automated approach to estimating intervertebral joint function from bony vertebral columns, and presents a new approach for estimating joint stiffness directly from oROM and morphometric measurements that can successfully reconstruct the craniocaudal patterns, but not magnitudes, derived from experimental data.

Effect of captivity on the vertebral bone microstructure of xenarthran mammals

The results add to the understanding of variation in mammalian bone microstructure, suggest caution when including captive specimens in bonemicrostructure research, and indicate the need to better replicate the habitats, diets, and behavior of animals in captivity.

Phenotypic integration in the carnivoran backbone and the evolution of functional differentiation in metameric structures

This work investigates morphological integration between all the presacral vertebrae of mammalian carnivorans to provide a better understanding of how regionalization in metameric structures evolves and proposes natural selection as the main factor shaping this pattern to stabilize some regions and to allow coordinate movements in others.

Study on the Structural Characteristics of Bird Necks and Their Static Motion Features in the Sagittal Plane

The necks of birds that possess complex structures, graceful curves, and flexible movements are perfect natural motion actuators. Studying their structural features, mechanic characteristics, and

Integrative Organismal Biology

This work develops a model of latch-mediated spring actuated (LaMSA) systems relevant to comparative biomechanics and bioinspired design and finds that the muscle forcevelocity trade-off and muscle activation have similar effects on directly actuated performance.

Joint mobility as a bridge between form and function.

The value of joint mobility as a lens through which to study articular form and function is discussed, so as to better illuminate the basics of 'how joints work' and be well positioned to tackle comparative investigations of the diverse repertoire of vertebrate animal motion.



The functional morphology of xenarthrous vertebrae in the armadillo Dasypus novemcinctus (Mammalia, Xenarthra)

Comparisons with functional data from other digging mammals indicate that the modified mechanical properties of the Dasypus column are consistent with an interpretation of xenarthra as digging adaptations and lend support to the idea that the order Xenarthra represents an early offshoot of placental mammals specialized for fossoriality.

Locomotor design of dolphin vertebral columns: bending mechanics and morphology of Delphinus delphis.

The dolphin's vertebral column has the mechanical capacity to help control the body's locomotor reconfigurations, to store elastic energy and to dampen oscillations.

The prominent ligamenta flava of the monkey and wallaby contrast with the robust discs of jaguar and tiger and illustrate two distinct mechanisms for resisting flexion in mammalian intervertebral joints.

Four-point bending was used to apply pure extension and flexion moments to the ligamentous lumbosacral spine and pelvic girdle of monkey, wallaby, tiger, jaguar and seal, suggesting that flexion resistance may be controlled by different mechanisms in different species.

Findings suggest that morphological and functional distinctions in primate vertebral anatomy may be more complex than suggested by a "long-backed" versus "short- backed" dichotomy.

Comparative axial morphology in pinnipeds and its correlation with aquatic locomotory behaviour

Comparison of the vertebral functional profiles in the fossil taxon Allodesmus kernensis with those of modern pinniped clades reveals that this extinct pinnipes may also have used a combination of pectoral and pelvic oscillatory movements during swimming, but in a manner opposite to that of Odobenus.

Overall, indrid lumbar vertebral morphology converges with that of hominoids, atelines, and possibly lorids, suggesting aLumbar adaptation to upright or "antipronograde" postures that require a reduction in spinal flexibility.

Ontogenetic allometry in the thoracolumbar spine of mammal species with differing gait use

Lumbar centrum length was more variable both ontogenetically and interspecifically than the other variables, suggesting heterochrony may be generating lumbar variation.

Functional morphology and three-dimensional kinematics of the thoraco-lumbar region of the spine of the two-toed sloth

It is suggested that a cranio-caudal pattern of angular deflections of the spine results from the out-of-phase movement of diagonal forelimbs and hindlimbs in other walking gaits, because it is not evident in the trot-like locomotion analyzed here.

Morphological and functional changes in the vertebral column with increasing aquatic adaptation in crocodylomorphs

The most important structures for determining RoM and stiffness of the trunk in Crocodylus were different in dorsoventral versus mediolateral bending, suggesting that changes in osteoderm and rib morphology over crocodylomorph evolution would have affected movements in some directions more than others.
