Summary 1 Contests may involve injurious fighting, other types of direct physical aggression
and communication. They occur over ownership access to mates and other resources that …

We investigate the roles of mitochondrial introgression and incomplete lineage sorting
during the phylogenetic history of crotaphytid lizards. Our Bayesian phylogenetic estimate …

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

Measurements of whole-organism performance traits have been useful in studies of
adaptation and phenotype–environment correlations. Bite force capacities may be tightly …

Perhaps the most remarkable thing about the elasmobranch feeding mechanism is its
functional diversity despite its morphological simplicity. Compared to the teleost skull, which …

How fast should animals move when trying to survive? Although many studies have
examined how fast animals can move, the fastest speed is not always best. For example, an …

Despite the empirical and theoretical attention paid to the role of sexual signals in resolving
agonistic interactions between conspecific males, few studies have applied a comparative …

When populations experience suboptimal conditions, the mechanisms involved in the
regulation of phenotypic variation can be challenged, resulting in increased phenotypic …

Questions: Does sexual selection operate on locomotor performance? Which taxa are likely
to have locomotor performance influenced by sexual selection? Methods: We reviewed …

Understanding the relationship between form and function is central to our comprehension
of how phenotypic diversity evolves. Traits involved in multiple activities, such as social …
