Parental investment, sexual selection and sex ratios
Conventional sex roles imply caring females and competitive males. The evolution of sex role divergence is widely attributed to anisogamy initiating a self‐reinforcing process. The initial asymmetryExpand

The evolution of mate choice and mating biases
We review the current status of three well–established models (direct benefits, indirect benefits and sensory drive) and one newcomer (antagonistic chase–away) of the evolution of mate choice and theExpand

Competition for early arrival in migratory birds
Summary 1. It is widely accepted that the arrival order of migratory birds is correlated with the condition of the birds, which leads to high quality individuals occupying prime sites. However,Expand

  • 28 February 2006
Two very basic ideas in sexual selection are heavily influenced by numbers of potential mates: the evolution of anisogamy, leading to sex role differentiation, and the frequency dependence ofExpand

Abstract Avoidance of incestuous matings is widely reported across many animal taxa, and the adaptive value of such behavior is explained through inbreeding depression. However, an old and somewhatExpand

The evolution of cooperative breeding through group augmentation
Some individuals (helpers) in cooperatively breeding species provide alloparental care and often suppress their own reproduction. Kin selection is clearly an important explanation for such behaviour,Expand

Unifying and Testing Models of Sexual Selection
Sexual reproduction is associated with the evolution of anisogamy and sperm-producing males and egg-laying females. The ensuing competition for mates has led to sexual selection and coevolution ofExpand

The sexual selection continuum
The evolution of mate choice for genetic benefits has become the tale of two hypotheses: Fisher's ‘run–away’ and ‘good genes’, or viability indicators. These hypotheses are often pitted against eachExpand

Ecological traps in changing environments: Ecological and evolutionary consequences of a behaviourally mediated Allee effect
Species usually have to use indirect cues when assessing habitat quality. This means that it is possible for humans to alter habitats in a way that causes a discrepancy between the cues and the trueExpand

Abstract In various models of sexual selection mediated by the viability indicator (“good genes”) mechanism, a sexually selected trait will truly reflect male quality if its expression is costly forExpand
