The study of alternative reproductive behaviors in fishes has contributed to our general
understanding of reproductive strategies and mating systems. Despite extensive research …

Abstract Atlantic salmon (Salmo solar, Salmonidae) show a diversity of life history,
behavioural and morphological adaptations for reproduction which have evolved as an …

A review of the literature reveals that, if females prefer traits that deviate from the population
mean, they usually prefer traits of greater quantity. In cases in which the sensory bases of …

Organisms compete for various resources in the course of sexual reproduction. First, there is
intrasexual competition for obtaining mates. Then, there is the need to exclude reproductive …

The breeding system of Atlantic salmon (Salmo salar) is shaped both by natural selection for
offspring production and by sexual selection for access to mating opportunities. These …

Adaptive variation can exist at a variety of scales in biological systems, including among
species, among local populations of a single species and among individuals within a single …

Alternative male mating tactics in species with external fertilization are often viewed as
coercive matings by low-quality males, when a male, unable to attract a female himself …

It is argued that recent analyses of the evolution of animal signals, which claim that
signalling systems must be honest indicators of underlying quality, have neglected a vital …

Sexual reproduction often involves substantial amounts of time and resources devoted to
competition for mates, courtship, and mate choice. These behaviors may be underpinned by …

It has been suggested that female preference for older mates in species without parental
care has evolved in response to an alleged higher genetic quality of older individuals. This …
