Paralarval turns were broader [higher mean length-specific turning radii (R/L mean )] and faster [higher mean...

In support of our hypothesis for stable landings, lovebirds timed half their landings (51.3%) when the perch was approaching either extreme of motion near zero...

Lauder ABSTRACT Fish swimming has classically been modeled as a rearwardly propagating wave of increasing amplitude and fixed frequency, based on kinematic data from large numbers of species in captivity. However, recent work on sharks swimming in natural environments has...

At slower speeds, coordination within thoracic segments was disrupted, although intersegmental coordination remained...

This suggests that a causative relationship between walking speed and foot sinkage depth within individual sand substates is not coupled with systematic changes in joint kinematics and muscle activity in the same way as is observed across sand substrates. * Author...

Here, we present new kinematic analyses of a previous glide experiment, and use the results to test...

Conversely, given the latter's comparatively higher correlation with bite force, we hypothesize that upper jaw depression contributes more...
