Abstract/OtherAbstract:
Ecological performance in animals is considered to be constrained by trade-offs between structural and physiological features. Some of the best anatomical and physiological data in support of this perspective are based on findings from canines, in which researchers have demonstrated skeletal shape trade-offs between running efficiency and strength. There has, however, actually been little examination of the link between these structural differences and relevant performance. In this paper I analyze the performance of six breeds of dogs in standardized weight pulling competitions. More brachycephalic shaped (broad headed) dogs are indeed significantly stronger than more dolichocephalic shaped (narrow headed) dogs even when controlling for body mass. Morphological trade-offs between power and running ability may be an important constraint on the evolution of canines and other terrestrial vertebrates.
