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...

To understand how muscle function changes with temperature, we held fish for 4 weeks at either 5 or 20°C and then ran muscle kinetic...

We found that quolls used slower speeds when moving on a narrower surface, but used similar gaits on both wide and narrow inclined structures. This suggests that a quoll's...

... and kinetics. Consistent with previous research, the spatiotemporal variables showed a sudden switch from walking to running in one transition step. During this step there was a sudden increase in forward speed, the so-called speed jump (0.42 m s −1 ). At total body level, this was reflected in a sudden...
