“…This method, known as full width at half maximum height (FWHM), is commonly used to determine trabecular geometry (e.g. Kupczik et al, 2007Kupczik et al, , 2009Macho et al, 2005;Panagiotopoulou and Cobb, 2009;Ryan and Krovitz, 2006;Spoor et al, 1993;Volpato et al, 2008). There is general consensus that the material properties, and in particular Young's modulus (E) values of cortical bone and the bone of each trabecula, referred to as trabecular bone material (Fig.…”

“…Many experimental studies support this hypothesis. For instance, macaques trained to walk bipedally have shown significantly different shape of femur and ilium than wild (quadrupedal) ones (Volpato, Viola, Nakatsukasa, Bondioli, & Macchiarelli, ). Therefore, different locomotor behaviors may leave different signatures inside bones.…”

The lifestyle of extinct tetrapods is often difficult to assess when clear morphological adaptations such as swimming paddles are absent. According to the hypothesis of bone functional adaptation, the architecture of trabecular bone adapts sensitively to physiological loadings. Previous studies have already shown a clear relation between trabecular architecture and locomotor behavior, mainly in mammals and birds. However, a link between trabecular architecture and lifestyle has rarely been examined. Here, we analyzed trabecular architecture of different clades of reptiles characterized by a wide range of lifestyles (aquatic, amphibious, generalist terrestrial, fossorial, and climbing). Humeri of squamates, turtles, and crocodylians have been scanned with microcomputed tomography. We selected spherical volumes of interest centered in the proximal metaphyses and measured trabecular spacing, thickness and number, degree of anisotropy, average branch length, bone volume fraction, bone surface density, and connectivity density. Only bone volume fraction showed a significant phylogenetic signal and its significant difference between squamates and other reptiles could be linked to their physiologies. We found negative allometric relationships for trabecular thickness and spacing, positive allometries for connectivity density and trabecular number and no dependence with size for degree of anisotropy and bone volume fraction. The different lifestyles are well separated in the morphological space using linear discriminant analyses, but a cross‐validation procedure indicated a limited predictive ability of the model. The trabecular bone anisotropy has shown a gradient in turtles and in squamates: higher values in amphibious than terrestrial taxa. These allometric scalings, previously emphasized in mammals and birds, seem to be valid for all amniotes. Discriminant analysis has offered, to some extent, a distinction of lifestyles, which however remains difficult to strictly discriminate. Trabecular architecture seems to be a promising tool to infer lifestyle of extinct tetrapods, especially those involved in the terrestrialization.

“…The greater thickness of the inferior cortex in bipedal hominini (Homo and Australopithecus) reflects the fact that the compressive load is relatively greater on the inferior cortex of the femoral neck than on the superior cortex; this seems to have induced the remodeling of the cortical bone of the femoral neck. However, the structural pattern of the trabecular bone and the orientation of the collagen fibers was maintained (Kalmey and Lovejoy 2002;Matsumura et al 2002Volpato et al 2008.…”

Cross-Sectional Morphology of the Femoral Neck of Wild Chimpanzees

To understand the mechanical effects of different modes of locomotion on the femoral neck of chimpanzees, we investigated the cross-sectional morphology of the femoral neck of 4 chimpanzees (Pan troglodytes schweinfurthii) collected from the Mahale Mountains, Tanzania. We performed serial computed tomography (CT) scans of the neck from the femoral head to the base of the neck perpendicular to the long axis of the neck. We measured the cortical thickness of the serial 5 cross sections of the neck region every 45°around the circumference, i.e., 8 points per section, and examined the cross-sectional properties of the mid-section. When we compared the superior and inferior parts of the cortical thickness of the femoral neck, the inferior part exhibited the greatest cortical thickness whereas the superior part had the smallest values in every specimen. Researchers have also observed such regional differences between superior and inferior cortical thicknesses in bipedal humans and other primates, although these differences are not as large in the chimpanzee as in bipedal hominini. The present study differed from the past study on hominini and chimpanzees in that the superior anterior (SA) part exhibited greater cortical thickness in chimpanzees. We believe these observations reflect the structural strengthening of parts of the chimpanzee femoral neck that is needed to accommodate the mechanical loads imposed by arboreal vertical climbing and terrestrial quadrupedal and bipedal locomotion.
