Mate choice by males has been recognized at least since Darwin's time, but its phylogenetic
distribution and effect on the evolution of female phenotypes remain poorly known …

Many fish populations have both resident and migratory individuals. Migrants usually grow
larger and have higher reproductive potential but lower survival than resident conspecifics …

Reproductive Biology of Teleost Fishes is the first integrated review of the reproductive
biology of the bony fishes, which are the most species-rich and diversified group of …

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

Darwin developed the theory of sexual selection to account for the evolution of weaponry,
ornamentation and other secondary sexual characters that are commonly more developed …

SUMMARY (i) To find out whether a mating preference could have initially evolved for
adaptive reasons, one must determine whether the preferred trait could have provided …

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 …

Although sexual selection theory has proved successful in explaining a wide array of male
ornaments, the function of ornaments occurring in females is largely unknown. Traditionally …

The latitudinal variation in clutch size found in many animal species, including Pacific
salmon, has been an enigmatic problem in ecology. We analyze egg number and egg size …

In the breeding system of Pacific salmon, females compete for oviposition territories, and
males compete to fertilize eggs. The natural selection in females and sexual selection in …
