Published: 9 December 2021
.... The kinematics showed that jumps were propelled by rapid and synchronous movements of both hind legs, with their trochantera moving first. The hind legs were 20–40% longer than the front legs, which was attributable to longer tibiae. It took 5–6 ms to accelerate to take-off velocities reaching 4.65 m s −1...

...M. Burrows; M. Dorosenko ABSTRACT The order Hemiptera includes jumping insects with the fastest take-off velocities, all generated by catapult mechanisms. It also contains the large family Miridae or plant bugs. Here, we analysed the jumping strategies and mechanisms of six mirid species from high...

...G. P. Sutton; M. Doroshenko; D. A. Cullen; M. Burrows ABSTRACT Many insects such as fleas, froghoppers and grasshoppers use a catapult mechanism to jump, and a direct consequence of this is that their take-off velocities are independent of their mass. In contrast, insects such as mantises, caddis...

... is unknown. Here, the effect that the train has on take-off flight in peacocks was quantified as the sum of the rates of change of the potential and kinetic energies of the body ( P CoM ) in birds with trains and following the train's removal. There was no significant difference between P CoM in birds...

...Gaëlle Bimbard; Dmitry Kolomenskiy; Olivier Bouteleux; Jérôme Casas; Ramiro Godoy-Diana SUMMARY Up to now, the take-off stage has remained an elusive phase of insect flight that was relatively poorly explored compared with other maneuvers. An overall assessment of the different mechanisms involved...

...Pauline Provini; Bret W. Tobalske; Kristen E. Crandell; Anick Abourachid SUMMARY Take-off mechanics are fundamental to the ecology and evolution of flying animals. Recent research has revealed that initial take-off velocity in birds is driven mostly by hindlimb forces. However, the contribution...

... the strongly selected-for flight apparatus with no apparent ecological trend present, i.e. flight so dominates bat locomotor morphology that other locomotor abilities tend to be derivative. The ability to take-off is crucial for all volant animals, as this marks the transition from terrestrial, arboreal...

... in wing kinematics and aerodynamics across flight speeds are gradual. Take-off flight performance scales with body size, but fully revealing the mechanisms responsible for this pattern awaits new study. Intermittent flight appears to reduce the power cost for flight, as some species flap–glide at slow...

...John J. Socha SUMMARY Among terrestrial vertebrate gliders, take-off presents a unique problem to flying snakes ( Chrysopelea ). Without legs, snakes must use fundamentally different kinematics to begin their aerial trajectories. To determine the effectiveness of different modes of take-off...

The absence of significant differences in hindlimb kinematics indicates that propulsion is essentially identical in leaping, parachuting...

...Graham N. Askew; Richard L. Marsh SUMMARY Take-off in birds at high speeds and steep angles of elevation requires a high burst power output. The mean power output of the pectoralis muscle of blue-breasted quail ( Coturnix chinensis ) during take-off is approximately 400 W kg -1 muscle...
