The importance of locomotion to evolutionary fitness has led to extensive study of primate
locomotor behavior, morphology and ecology. Most previous research has focused on adult …

Despite differences in the assumed ecological context in competing evolutionary scenarios
for early primate locomotion, there appears to be consensus about the adaptive significance …

Vertebrates employ an impressive range of strategies for coordinating their limb movements
while walking. Although this gait variation has been quantified and hypotheses for its origins …

Speed regulation in animals involves stride frequency and stride length. While the
relationship between these variables has been well documented, it remains unresolved …

Fine-branch models have long played a central role in primate evolutionary research.
Nevertheless, recent studies of positional behavior in nonprimate arboreal mammals have …

Arboreal environments require overcoming navigational challenges not typically
encountered in other terrestrial habitats. Supports are unevenly distributed and vary in …

During quadrupedal walking, most primates utilize diagonal-sequence diagonal-couplet
gaits, large limb excursions and hindlimb-biased limb loading. These gait characteristics are …

Locomotion is precarious in an arboreal habitat, where supports can vary in both diameter
and level of compliance. Several previous studies have evaluated the influence of substrate …

Arboreal supports impose a set of locomotor challenges not typically encountered in other
terrestrial ecosystems. Because all arboreal animals must negotiate this common set of …

Arm-swinging is a locomotor mode observed only in primates, in which the hindlimbs no
longer have a weight bearing function and the forelimbs must propel the body forward and …
