...Jason P. Odell; Mark A. Chappell; Kathryn A. Dickson SUMMARY We examined the mechanistic basis for two whole-animal performance traits,aerobic capacity and burst speed, in six laboratory-reared Trinidadian guppy populations from different native drainages with contrasting levels of predation. Using...

...Stephen M. Secor; Bruce C. Jayne; Albert F. Bennett ABSTRACT We measured the performance (burst speed and endurance) and the energetic cost of sidewinding locomotion for the viperid snake Crotalus cerastes . The linear scaling regressions relating log mass to log burst speed and log endurance have...

...Albert F. Bennett ABSTRACT The capacities of animals for activity (burst speed, maximal exertion, endurance) are examined in relation to their selective importance in extant populations and the pattern of their evolution in major animal taxa. Activity capacities have been demonstrated to be both...
