...Edwin Dickinson; Melody W. Young; Charles J. Kim; Michael Hadjiargyrou; Michael C. Granatosky ABSTRACT The ability to securely grasp substrates of variable diameter is critical to arboreal animals. Arboreal specialists have emerged across several vertebrate lineages – including mammals, lizards...

...Hiroshi Matsui; Ei-Ichi Izawa ABSTRACT Pecking in birds is analogous to reaching and grasping movements in primates. Earlier studies on visuomotor control in birds, which were conducted mostly in pigeons, suggested that avian pecking is controlled feedforwardly, and is out of the control of visual...

... are similar to what has been observed for lizards and primates, suggesting that the mechanics of narrow substrate locomotion drive the kinematics of movement independent of morphology and phylogeny. To test the effect of the substrate incline and diameter on the type of grasping used by each individual...
