The study of phenotypic evolution should be an integrative endeavor that combines different
approaches and crosses disciplinary and phylogenetic boundaries to consider complex …

Hypothesis: Natural and sexual selection should be stronger on whole-organism functional
performance traits (sprinting, biting) than on correlated morphological variables. Organisms …

In its simplest definition, a trait is a surrogate of organismal performance, and this meaning
of the term has been used by evolutionists for a long time. Over the last three decades …

Sexual selection operates by acting on variation in mating success. However, since
selection acts on whole‐organism manifestations (ie, performance) of underlying …

For almost 40 years, studies of whole-organism performance have formed a cornerstone of
evolutionary physiology. Although its utility as a heuristic guide is beyond question, and we …

The accessibility of new genomic resources, high‐throughput molecular technologies and
analytical approaches such as genome scans have made finding genes contributing to …

Body size is a key life-history trait influencing all aspects of an organism's biology. Ants
provide an interesting model for examining body-size variation because of the high degree …

Should they stay or should they leave? The age at which young transition between life
stages, such as living in a nest versus leaving it, differs among species and the reasons why …

Increasingly, drone-based photogrammetry has been used to measure size and body
condition changes in marine megafauna. A broad range of platforms, sensors, and …

For most vertebrates, locomotion is a fundamental component of prey capture. Despite this
ubiquitous link, few studies have quantified the integration of these complex systems …
