Testosterone, Endurance, and Darwinian Fitness: Natural and Sexual Selection on the Physiological Bases of Alternative Male Behaviors in Side-Blotched Lizards
The mechanistic bases of natural and sexual selection on physiological and behavioral traits were examined in male morphs of three colors of the side-blotched lizard, Uta stansburiana.Expand

Size and shape: the developmental regulation of static allometry in insects
Among all organisms, the size of each body part or organ scales with overall body size, a phenomenon called allometry. The study of shape and form has attracted enormous interest from biologists, butExpand

Natural Selection and Developmental Constraints in the Evolution of Allometries
In animals, scaling relationships between appendages and body size exhibit high interspecific variation but low intraspecific variation. This pattern could result from natural selection for specificExpand

INTERNAL AND EXTERNAL CONSTRAINTS IN THE EVOLUTION OF MORPHOLOGICAL ALLOMETRIES IN A BUTTERFLY
Abstract Much diversity in animal morphology results from variation in the relative size of morphological traits. The scaling relationships, or allometries, that describe relative trait size can varyExpand

KIN‐MEDIATED MORPHOGENESIS IN FACULTATIVELY CANNIBALISTIC TADPOLES
Inclusive fitness theory predicts that organisms can increase their fitness by helping or not harming relatives, and many animals modify their behavior toward kin in a manner consistent with thisExpand

New perspectives on the evolution of exaggerated traits
The scaling of body parts is central to the evolution of morphology and shape. Most traits scale proportionally with each other and body size such that larger adults are essentially magnifiedExpand

Condition-dependent expression of trophic polyphenism: effects of individual size and competitive ability
Understanding the adaptive significance of alternative phenotypes may require knowing how the internal state of an organism affects the relationship between phenotypic variation and fitness acrossExpand

Costs of reproduction and geographic variation in the reproductive tactics of the mosquito Aedes triseriatus
Abstract The eastern treehole mosquito, Aedes triseriatus (Say), was used in two experiments testing assumptions and predictions of life history theory. Experiment 1 employed direct, phenotypicExpand
