Sex differences in habitat use, positional behavior, and gaits of Golden Snub-Nosed Monkeys (Rhinopithecus roxellana) in the Qinling Mountains, Shaanxi, China
Footloose
OBJECTIVES: The competing functional demands of diarthrodial joints, permitting mobility while retaining enough stability to transmit forces across the joint, have been linked with the shape and size of the joint's articular surfaces. A clear understanding of the relationship between joint morphology and joint movement potential is important for reconstructing locomotor behaviors in fossil taxa. METHODS: In a sample of matched tali and calcanei o…
The mechanical origins of arm-swinging
Do forelimb shape and peak forces co‐vary in strepsirrhines
OBJECTIVES: In this study, we explore whether ground reaction forces recorded during horizontal walking co-vary with the shape of the long bones of the forelimb in strepsirrhines. To do so, we quantify (1) the shape of the shaft and articular surfaces of each long bone of the forelimb, (2) the peak vertical, mediolateral, and horizontal ground reaction forces applied by the forelimb during arboreal locomotion, and (3) the relationship between the…
An anatomical and mechanical analysis of the douc monkey (genus Pygathrix ), and its role in understanding the evolution of brachiation
OBJECTIVES: Pygathrix is an understudied Asian colobine unusual among the Old World monkeys for its use of arm-swinging. Little data exists on the anatomy and mechanics of brachiation in this genus. Here, we consider this colobine to gain insight into the parallel evolution of suspensory behavior in primates. MATERIALS AND METHODS: This study compares axial and appendicular morphological variables of Pygathrix with other Asian colobines. Addition…
Functional associations between support use and forelimb shape in strepsirrhines and their relevance to inferring locomotor behavior in early primates
Patterns of quadrupedal locomotion in a vertical clinging and leaping primate ( Propithecus coquereli ) with implications for understanding the functional demands of primate quadrupedal locomotion
OBJECTIVES: Many primates exhibit a suite of characteristics that distinguish their quadrupedal gaits from non-primate mammals including the use of a diagonal sequence gait, a relatively protracted humerus at touchdown, and relatively high peak vertical forces on the hindlimbs compared to the forelimbs. These characteristics are thought to have evolved together in early, small-bodied primates possibly in response to the mechanical demands of navi…
Spatial patterning of bone stiffness in the anterior mandibular corpus of M acaca fascicularis
Elastic modulus of bone from the anterior mandibular corpus was determined via microindentation in a mixed‐sex ontogenetic sample ( N = 14) of Macaca fascicularis . This investigation focused on the hypothesis that material heterogeneity in the macaque mandibular symphysis—provided an accounting of age and sex variation—is explicable as a means to homogenize strains in this region. Experimental data and theoretical models of masticatory loading i…
Distinct functional roles of primate grasping hands and feet during arboreal quadrupedal locomotion
Ontogeny of material stiffness heterogeneity in the macaque mandibular corpus
Evidence is accumulating that bone material stiffness increases during ontogeny, and the role of elastic modulus in conditioning attributes of strength and toughness is therefore a focus of ongoing investigation. Developmental changes in structural properties of the primate mandible have been documented, but comparatively little is known about changes in material heterogeneity and their impact on biomechanical behavior. We examine a cross‐section…
Lumbar vertebral morphology of flying, gliding, and suspensory mammals
Reduced stiffness of alveolar bone in the colobine mandible
Alveolar bone has several mechanical functions, including tooth support and accommodation of occlusal and other masticatory forces. Its unique functional‐mechanical environment is reflected by its structural characteristics, but whether alveolar bone is materially distinct from bone elsewhere in the primate facial skeleton is uncertain. This uncertainty is attributable not only to a limited amount of data but also to conflicting findings among th…
