(Invited Article) Abstract Sexual size dimorphism (SSD) is widespread and variable among
animals. According to the differential equilibrium model, SSD in a given species is expected …

Males and females share most of their genomes and express many of the same traits, yet the
sexes often have markedly different selective optima for these shared traits. This sexually …

The integration of macroevolutionary pattern with developmental mechanism presents an
outstanding challenge for studies of phenotypic evolution. Here, we use a combination of …

Males are predicted to compete for reproductive opportunities, with sexual selection driving
the evolution of large body size and weaponry through the advantage they confer for access …

Life‐history theory predicts that organisms will provide an optimal level of parental
investment for offspring survival balanced against the effects on their own survival and future …

Sexual size dimorphism (SSD) is thought to evolve due to sex differences in selection on
body size, but it is largely unknown whether intraspecific variation in SSD reflects differences …

Comparative analyses have found that relative testis size is a strong predictor of the
prevalence of sperm competition for many taxa, including mammals, yet underlying this …

Traditionally, studies of intrasexual selection have focused on single traits that are more
exaggerated in males. Relatively little is known about systems in which traits are larger in …

African pygmy mice (subgenus Nannomys) are a group of small murine rodents that are
widespread throughout Sub-Saharan Africa. Although this group has long been recognized …

Sex differences in the mean trait expression are well documented, not only for traits that are
directly associated with reproduction. Less is known about how the variability of traits differs …
