...-distance free-flights between two perches. The greatest accelerations were observed during the second wingbeat of takeoff. The wings were responsible for the majority of acceleration during takeoff and landing, with the legs contributing only one-quarter of the acceleration. Parameters relating to...

... understood, despite numerous snake species being arboreal. We quantified the kinematics and performance of corn snakes ( Elaphe guttata ) moving on seven cylinders (diameters 1.6–21 cm) with five inclines (horizontal, ±45° and±90°) and through horizontal tunnels of corresponding widths. When perches were...

... flight of hummingbirds can provide novel insight into the take-off mechanics that will be required for micro-air vehicles. During take-off by hummingbirds, we measured hindlimb forces on a perch mounted with strain gauges and filmed wingbeat kinematics with high-speed video. Whereas other birds obtain 80...

...JAY A. NELSON The objectives of this study were to determine if environmental acidity reduces swimming performance in the acid-tolerant yellow perch ( Perca flavescens ) and to use swimming performance as an indicator of fitness in testing whether fish from naturally acidic environments perform...
