It is widely agreed that fecundity selection and sexual selection are the major evolutionary
forces that select for larger body size in most organisms. The general, equilibrium view is …

Sexual size dimorphism (SSD) is common in both plants and animals, and current evidence
suggests that it reflects the adaptation of males and females to their different reproductive …

This book presents the first unified conceptual and statistical framework for understanding
the evolution of reproductive strategies. Using the concept of the opportunity for sexual …

Over the past decades, Atlantic salmon (Salmo salar, Salmonidae) has emerged as a model
system for sexual maturation research, owing to the high diversity of life history strategies …

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

Human harvest of phenotypically desirable animals from wild populations imposes selection
that can reduce the frequencies of those desirable phenotypes. Hunting and fishing contrast …

Accumulating data indicate that hatchery fish have lower fitness in natural environments
than wild fish. This fitness decline can occur very quickly, sometimes following only one or …

Among vertebrates, fish show by far the greatest variability of alternative reproductive tactics
(ARTs). Usually, males attempting to monopolize access to females or fertilizations are …
