Colorful ornaments are hypothesized to have evolved in response to sexual selection for honest signals of individual quality that provide information about potential mates. Red carotenoid coloration is common in diverse groups, and in some vertebrate taxa, red coloration is a sexually selected trait whereby mates with the reddest ornaments are preferred. Despite being widespread among invertebrates,...
The fitness of a eukaryote hinges on the coordinated function of the products of its nuclear and mitochondrial genomes in achieving oxidative phosphorylation (OXPHOS). I propose that sexual selection plays a key role in the maintenance of mitonuclear coadaptation across generations because it enables pre‐zygotic sorting for coadapted mitonuclear genotypes. At each new generation, sexual reproduction...

AbstractCondition is a nearly ubiquitous term in the behavioural, physiological and evolutionary ecology literature; however, existing definitions are incomplete or ambiguous. This poor conceptualization has led to confusion regarding what is being signalled by condition‐dependent traits and how to interpret links between ornamentation and individual characteristics...
