Positive allometry of signalling traits has often been taken as evidence for sexual selection.
However, few studies have explored interspecific differences in allometric scaling …

Visual ornaments have long been assumed to evolve hyper‐allometry as an outcome of
sexual selection. Yet growing evidence suggests many sexually selected morphologies can …

Male sexually selected signals can indicate competitive ability by honestly signaling fitness-
relevant traits such as condition or performance. However, behavior can also influence …

The severity of parasitic infections can mediate the differential expression of signals among
populations, creating variation in signal intensity. Male signals (patch size and brightness) …

Predator–prey interactions drive the evolution of prey visual camouflage, but prey species
also must remain conspicuous to their conspecifics for social signaling purposes. Whether …

Identifying how ecotourism affects wildlife can lower its environmental impact. Human
presence is an inherent component of ecotourism, which can impact animal behavior …

Colorful sexual traits are shaped by the opposing pressures of natural and sexual selection.
Although increased conspicuousness improves mating success, an individual bearing …

Sexual selection favors conspicuous signals that animals can use to communicate with
conspecifics and/or to attract mates. However, natural and sexual selection are often in …
