Meléndez-Morales D,de Paz-Lugo P,Meléndez-Hevia E. Glycolysis activity in flight muscles of birds according to their physiological function An experimental model in vitro to study aerobic and anaerobic glycolysis activity separately[J].Molecular & Cellular Biochemistry,2009,(1-2):127-135....
Biomechanics of bird flight The primary flight muscles of birds, the pectoralis and supracoracoideus, are designed for work and power output, with large stress ( force per unit ... Tobalske,BW - 《Journal of Experimental Biology》 被引量: 301发表: 2007年 Heart mass and the maximum cardiac...
The flight muscles of the gray catbird ( Dumetella carolinensis ) were examined to determine if short term adjustments occur in the activity of key catabolic enzymes during preparation for long distance migration. The aerobic capacity of... RL Marsh - 《Journal of Comparative Physiology》 被引量...
No two sorts of birds practise quite the same sort of flight; the varieties are infinite; but two classes may be roughly seen. Any shi that crosses the Pacific is accompanied for many days by the smaller albatross, Which may keep company with the vessel for an hour without visible or more...
Pouncing might then have turned into swooping as feathers and flight muscles provided better liftoff. Evolving to be smaller in size would have been another factor essential for becoming airborne, but that occurred after the time of Archaeopteryx. In fact, it seems that Archaeopteryx was unable to...
The results of one such analysis, of the maximum sustainable flight performance of migratory birds, leads to the conclusion that the efficiency of the flight muscles appears to scale as Mb 0.14. However, much of this apparent scaling may be an artefact of the application and assumptions of the...
Flapping flight places strenuous requirements on the physiological performance of an animal. Bird flight muscles, particularly at smaller body sizes, generally contract at high frequencies and do substantial work in order to produce the aerodynamic power needed to support the animal's weight in the ai...
amost birds have approximately 175 different muscles,mainly controlling the wings,skin,and legs.The largest muscles in the bird are the pectorals,or the breast muscles,which control the wings and make up about 15-25% of a flight bird's body weight.They provide the powerful wing stroke essent...
the duck is supreme. It comes nearer to the engines with which man has 'conquered' the air, as he boasts. Duck, and like them the pigeons, are endowed with steel-like muscles, that are a good part of the weight of the bird, and these will ply the short wings with such irresistible...
The high burst power outputs found in the flight muscles of quail and similar birds are limited to very brief efforts before fatigue occurs. This strong but short flight performance is well-suited to the rapid-response anti-predation strategy of these birds that involves a short flight coupled ...
