Fig. 2. (A) Force platform used to measure dynamics of climbing geckos
Hemidactylus garnotii. (B) Axis conventions used in this study.
Positive foreaft forces (+x; blue) correspond to wall reaction
forces that would accelerate a mass upwards. The force of gravity acts in the
x direction. Positive normal forces (+y; red)
correspond to wall reaction forces that would accelerate a mass away from the
force plate, whereas negative normal forces (y) correspond to
wall reaction forces that would accelerate a mass towards the force plate. The
z axis was the lateral dimension and corresponds to forces directed
to the animals right or left. Positive lateral forces (+z; green)
correspond to wall reaction forces that would accelerate a mass to the
animal's right, whereas negative lateral forces (z) correspond
to wall reaction forces that would accelerate a mass to the animal's left.
