▪ Abstract Understanding adaptation in morphological and physiological traits requires
elucidation of how traits relate to whole-organism performance and how performance relates …

▪ Abstract The performance of an organism is the crucial link between its phenotype and its
ecological success. When does an organism's morphology affect its performance …

Adaptive radiation is the evolution of diversity within a rapidly multiplying lineage. It can
cause a single ancestral species to differentiate into an impressively vast array of species …

Behavior is one of the major architects of evolution: by behaviorally modifying how they
interact with their environments, organisms can influence natural selection, amplifying it in …

Some biologists embrace the classical view that changes in behavior inevitably initiate or
drive evolutionary changes in other traits, yet others note that behavior sometimes inhibits …

Studies of ecomorphology–the relationship among species between morphology and
ecology–contain two implicit and rarely tested hypotheses:(1) that morphological differences …

Relationships between morphology, physiology, or biochemistry, on the one hand, and
behavior and ecology, on the other, have been widely documented, as this volume attests …

I tested biomechanical predictions that morphological proportions (snout–vent length,
forelimb length, hindlimb length, tail length, and mass) and maximal sprinting and jumping …

Organismal performance abilities occupy a central position in phenotypic evolution; they are
determined by suites of interacting lower‐level traits (eg, morphology and physiology) and …

ABSTRACT Individual Atlantic cod (Gadus morhua) were exercised using three different
measures of swimming performance.(1) An endurance test (critical swimming speed, U crit …
