The degree to which many of these biomechanical characteristics differ from...

However, it is unknown whether two- and three-toed sloths converge in their use of limb kinetics and if these patterns are comparable to how primates perform arboreal suspensory locomotion...

Our findings suggest that shooting-related fin maneuvers are needed to stabilize the shooter, and that these maneuvers are an important component...

... attention should be placed on understanding asymmetrical gait dynamics for insight into hypotheses concerning early primate locomotor evolution. Summary: Free-ranging callitrichine primates adjust aspects of asymmetrical gait kinematics to promote stability when moving over arboreal substrates varying...

...Wael Salem; Benjamin Cellini; Mark A. Frye; Jean-Michel Mongeau ABSTRACT Most animals shift gaze by a ‘fixate and saccade’ strategy, where the fixation phase stabilizes background motion. A logical prerequisite for robust detection and tracking of moving foreground objects, therefore...

..., the tail might provide passive pitch stability if it produced very low or negative lift. Alternatively, aeronautical principles might suggest strategies that allow the tail to reduce inviscid, induced drag: if the wings and tail act in different horizontal planes, they might benefit from biplane-like...

Either aerodynamic or inertial forces generated by appendages and other structures, such as the tail, may...

By decreasing the time spent in a low-stability configuration – effectively ‘limping’ over less-stable phases of the stride – spiders increased the overall stability of the less statically...

We discuss the observed scaling of avian bipedal gait in relation to mechanical demands for force, work and power relative to muscle actuator capacity, muscle activation costs related to leg cycling frequency, and considerations of stability...
