THERE is considerable controversy about what females gain from mate choice in a lekking species in which males provide no obvious resources. Females may gain direct benefits such as safe copula-tions or increased fertility by mating with particular males, or they may gain indirect benefits for their offspring1–3. It is difficult to look for paternal effects on offspring performance because it is hard to control for any differences in the material and genetic contribution provided by the female… Expand

Potential genetic benefits of mate selection in whitefish
TLDR
The ‘good genes’ effect was larger than expected from theory: optimal mate selection would have improved offspring survival during the epidemic by about 12% (or reduce mortality by about 66%) as compared with random mating. Expand
Characteristics of brown trout males influence growth and survival of their offspring
TLDR
Characteristics of the males (fathers) influences the quality of the offspring, and there seem to be benefits for the females both to choose among potential mates and to spawn with the most dominant male. Expand
Fisherian flies: benefits of female choice in a lekking sandfly
TLDR
The results indicate that Fisherian benefits are at least partly responsible for maintaining female choice at L. longipalpis leks and indicate the importance of testing all putative benefits concurrently in exploring the maintenance of female mate choice. Expand
Multi-male mating and female choice increase offspring growth in the spider Neriene litigiosa (Linyphiidae)
  • P. Watson
  • Biology, Medicine
  • Animal Behaviour
  • 1998
TLDR
The results support the hypotheses that the preference for large males yields viability benefits to offspring and that polyandry can augment the benefits of selective mating. Expand
Potential fitness benefits from mate selection in the Atlantic cod (Gadus morhua)
TLDR
Cod (Gadus morhua L.), an externally fertilizing species where males provide nothing but sperm, is used to examine the potential of optimal mate selection with respect to offspring survival and it is found that offspring survival was dependent on which female was mated with which male and that optimalmate selection has the potential to increase mean offspring survival. Expand
Indirect fitness consequences of mate choice in sticklebacks: offspring of brighter males grow slowly but resist parasitic infections
TLDR
The association with reduced growth suggests a mechanism for the maintenance of heritable variation in both disease resistance and male sexual coloration, and suggests that highly ornamented males confer disease resistance on their offspring. Expand
Egg investment is influenced by male attractiveness in the mallard
TLDR
It is shown that individual female mallard (Anas platyrhynchos) lay larger eggs after copulating with preferred males and smaller eggs afterCopulating with less preferred males, showing that differences between half-sibs cannot always be attributed to paternal or maternal genetic effects. Expand
Peacocks lek with relatives even in the absence of social and environmental cues
TLDR
Two independent sets of data are presented that show that peacocks (Pavo cristatus) display close to their kin and indicate that birds can evolve a means of kin association that does not involve learning the characteristics of relatives or the use of environmental cues. Expand
Male sexual attractiveness affects the investment of maternal resources into the eggs in peafowl (Pavo cristatus)
TLDR
Results show that the association between paternal phenotype and offspring quality could arise via a differential maternal investment, and suggest that, if ornamented males do transmit good genes to the progeny, the maternal differential investment can amplify the effect of such good genes on the offspring fitness. Expand
Social constraints on female mate preferences in mallards, Anas platyrhynchos, decrease offspring viability and mother productivity
TLDR
This study is among the few studies of birds and the only study of a species with forced copulation showing fitness deficits for offspring and mothers from enforced reproduction with nonpreferred males. Expand

Peacocks with low mating success are more likely to suffer predation
TLDR
If females mate with attractive males because their offspring have a higher chance of survival then it might be expected that preferred males would also show a higher chances of survival, since these males would possess the `good genes'. Expand
Heritable variation in a plumage indicator of viability in male great tits Parus major
TLDR
The results show that females mating with attractive male great tits realize an indirect fitness advantage, and that the viability of male offspring was correlated with the plumage traits of their putative father. Expand
Peahens prefer peacocks with elaborate trains
TLDR
Observations of one lek, consisting of 10 males, showed that there was considerable variance in mating success and analysis of female behaviour provided good evidence that this non-random mating is a result of a female preference, supporting Darwin's hypothesis that the peacock's train has evolved, at least in part, as a result. Expand
Lekking in the black grouse— a test of male viability
TLDR
It is reported here that by choosing victorious males, females mate with males that are most likely to survive the following six months, which supports a basic assumption of the 'good gene' models. Expand
Preferred males acquire mates of higher phenotypic quality

  • Biology
  • Proceedings of the Royal Society of London. Series B: Biological Sciences
  • 1991
TLDR
Observations using males with naturally varying and experimentally manipulated tails show that females mated to long-tailed males were heavier, bred earlier, produced more offspring per season and were much more likely to survive to the next breeding season that were females mating to short-tailed male swallows, the first demonstration that preferred males actually obtain mates of high phenotypic quality. Expand
The evolution of mating preferences and the paradox of the lek
TLDR
There is growing support for direct selection, in which preferences evolve because of their direct effects on female fitness rather than the genetic effects on offspring resulting from mate choice. Expand
INTRASPECIFIC VARIATION IN EGG SIZE AND EGG COMPOSITION IN BIRDS: EFFECTS ON OFFSPRING FITNESS
  • T. Williams
  • Biology, Medicine
  • Biological reviews of the Cambridge Philosophical Society
  • 1994
TLDR
It is suggested that the most important effect of variation in egg size might be in determining the probability of offspring survival in the first few days after hatching, and the hypothesis that large eggs give rise to heavier chicks at hatching is supported. Expand
THE EVOLUTION OF COSTLY MATE PREFERENCES II. THE “HANDICAP” PRINCIPLE
TLDR
A general additive quantitative genetic model is used to study the evolution of costly female mate choice by the “handicap” principle and applies to other sources of fitness variation like migration and host‐parasite coevolution, which cause effects equivalent to biased mutation. Expand
THE EVOLUTION OF COSTLY MATE PREFERENCES I. FISHER AND BIASED MUTATION
TLDR
This analysis shows that evolutionary stable exaggeration of female preference can be achieved if mutation pressure on the male character is biased, that is, mutation has a directional effect at this equilibrium female fitness is not maximized. Expand
