Assessment strategy and the evolution of fighting behaviour.
  • G. A. Parker
  • Economics, Medicine
  • Journal of theoretical biology
  • 1 September 1974
The view is examined that the adaptive value of conventional aspects of fighting behaviour is for assessment of relative RHP (resource holding power) of the combatants. Outcomes of aggressiveExpand

The logic of asymmetric contests
Abstract A theoretical analysis is made of the evolution of behavioural strategies in contest situations. It is assumed that behaviour will evolve so as to maximize individual fitness. If so, aExpand

Sperm Competition in Fishes: The Evolution of Testis Size and Ejaculate Characteristics
Fishes show one of the widest ranges of sperm competition intensity of any animal group. Here we present a comparative study whose aim is to investigate the effect of relative intensity of spermExpand

  • 28 February 2006
Sexual conflict is a conflict between the evolutionary interests of individuals of the two sexes. The sexes can have different trait optima but this need not imply conflict if their optima can beExpand

Sperm competition and ejaculate economics
Sperm competition was identified in 1970 as a pervasive selective force in post‐copulatory sexual selection that occurs when the ejaculates of different males compete to fertilise a given set of ova.Expand

Punishment in animal societies
Although positive reciprocity (reciprocal altruism) has been a focus of interest in evolutionary biology, negative reciprocity (retaliatory infliction of fitness reduction) has been largely ignored.Expand

Intrafamilial conflict and parental investment: a synthesis.
We outline and develop current theory on how inherent genetic conflicts of interest between the various family members can affect the flow of parental investment from parents to offspring, andExpand

Sexual conflict and speciation.
We review the significance of two forms of sexual conflict (different evolutionary interests of the two sexes) for genetic differentiation of populations and the evolution of reproductive isolation.Expand

Sperm (ejaculate) competition in Drosophila melanogaster, and the reproductive value of females to males in relation to female age and mating status
1 In double mating experiments with Drosophila melanogaster in which one male had been irradiated, it was confirmed that sperm displacement is extensive, i.e. the second male to mate displaces mostExpand

Sexual coercion in animal societies
Abstract In a wide range of animal species, males coerce females to mate with them, either by physically forcing them to mate, by harassing them until they mate or by punishing persistent refusal toExpand
