Robust jumping performance and elastic energy recovery from compliant perches in tree frogs.
Arboreal animals often move on compliant branches, which may deform substantially under loads, absorbing energy. Energy stored in a compliant substrate may be returned to the animal or it may be lost. In all cases studied so far, animals jumping from a static start lose all of the energy imparted to compliant substrates and performance is reduced. Cuban tree frogs (Osteopilus septentrionalis) a...

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...

Zug, George R. Anuran Locomotion—Structure and Function, 2: Jumping Performance of Semiaquatic, Terrestrial, and Arboreal Frogs. Smithsonian Contribution to Zoology, number 276, 31 pages, 9 figures, 15 tables, 1978.—Frogs evolved as jumping machines. The earliest recognized anuran fossil possessed a foreshortened body and elongated hindlimbs, primary adaptations for jumping. The majority of ext...
متن کاملPerformance of guinea fowl Numida meleagris during jumping requires storage and release of elastic energy.
The ability of birds to perform effective jumps may play an important role in predator avoidance and flight initiation. Jumping can provide the vertical acceleration necessary for a rapid takeoff, which may be particularly important for ground-dwelling birds such as phasianids. We hypothesized that by making use of elastic energy storage and release, the leg muscles could provide the large powe...
متن کاملChasing maximal performance: a cautionary tale from the celebrated jumping frogs of Calaveras County.
Maximal performance is an essential metric for understanding many aspects of an organism's biology, but it can be difficult to determine because a measured maximum may reflect only a peak level of effort, not a physiological limit. We used a unique opportunity provided by a frog jumping contest to evaluate the validity of existing laboratory estimates of maximum jumping performance in bullfrogs...
