Speed and Endurance Do Not Trade Off in Phrynosomatid Lizards.
Trade-offs are a common focus of study in evolutionary biology and in studies of locomotor physiology and biomechanics. A previous comparative study of 12 species of European lacertid lizards found a statistically significant negative correlation between residual locomotor speed and stamina (controlling for variation in body size), consistent with ideas about trade-offs in performance based on ...
متن کاملSpeed and stamina trade-off in lacertid lizards.
Morphological and physiological considerations suggest that sprinting ability and endurance capacity put conflicting demands on the design of an animal's locomotor apparatus and therefore cannot be maximized simultaneously. To test this hypothesis, we correlated size-corrected maximal sprint speed and stamina of 12 species of lacertid lizards. Phylogenetically independent contrasts of sprint sp...
متن کاملEnergy-Delay Trade-off in Digital Design
Circuit design will be challenging in the future. Meeting high-speed performance requirement while dissipating low energy cannot be accomplished easily. The ability to identify the energy-delay trade-off during the initial design process allows designers to optimize the overall circuit performance. Using an inverter chain as a representative logic element, this paper investigates the energy-del...
متن کاملA trade-off between guerrilla and phalanx growth forms in Leymus secalinus under different nutrient supplies.
BACKGROUND AND AIMS A phalanx growth form enables clonal plants to make better use of resource-rich patches, whereas a guerrilla growth form provides them with opportunities to escape from resource-poor sites. Leymus secalinus produces both spreading (guerrilla form) and clumping ramets (phalanx form). Here, the hypothesis that a trade-off between the two growth forms in L. secalinus exists und...
متن کاملClutch Frequency Affects the Offspring Size-Number Trade-Off in Lizards
BACKGROUND Studies of lizards have shown that offspring size cannot be altered by manipulating clutch size in species with a high clutch frequency. This raises a question of whether clutch frequency has a key role in influencing the offspring size-number trade-off in lizards. METHODOLOGY/PRINCIPAL FINDINGS To test the hypothesis that females reproducing more frequently are less likely to trad...
