Abstract The maintenance of female polyandry has traditionally been attributed to the material (direct) benefits derived from male mating resources (e.g. nuptial gifts) accrued by multiple mating. However, genetic (indirect) benefits offer a more robust explanation since only polyandrous, not monandrous, females may gain both material benefits from multiple mating and genetic benefits from multiple sires. Discriminating between material and genetic benefits is essential when addressing the… Expand

Figures from this paper

Polyandry occurs because females initially trade sex for protection
TLDR
In the fiddler crab Uca mjoebergi, females mate multiply using two distinct mating tactics: surface and burrow mating, and it is found that females gained a different benefit from each type of mating. Expand
Polyandry provides reproductive and genetic benefits in colonising populations
TLDR
The results show that even mild polyandry provides both reproductive and genetic benefits for colonising populations, with results suggesting that poly andry acts to both protect against mating with incompatible males through the founder event, and reduce inbreeding depression as the colonisation proceeds for 10 generations. Expand
Polyandrous females acquire indirect benefits in a nuptial feeding species
TLDR
Polyandry increased female reproductive success by increasing the probability of oviposition, and egg hatching success indicating that indirect benefits arise from mating with several different mating partners rather than resources transferred by males. Expand
Good genes and the maternal effects of polyandry on offspring reproductive success in the bulb mite
TLDR
Polyandry had no significant effect on daughter fecundity, thus indicating that any previously documented effects must have been genetic, and the maternal effects of polyandry should be taken into account whenever its costs and benefits are being considered. Expand
Polyandry in the absence of fitness benefits in a species with female-biased sexual size dimorphism
TLDR
It is found that paternity in polyandric females follows a pattern of sperm mixing, and Mecaphesa celer females' decisions regarding mating with multiple males do not appear to be influenced by comparisons of male attributes or by future fitness benefits. Expand
Multiple mating in a lizard increases fecundity but provides no evidence for genetic benefits
TLDR
It is suggested that polyandry in E. quoyii possibly evolved as a mechanism to ensure fertilization of ova, similar to what has been reported in some other taxa. Expand
POLYANDRY PROMOTES ENHANCED OFFSPRING SURVIVAL IN DECORATED CRICKETS
TLDR
Results suggest that the benefit females gain from multiple mating is influenced primarily by genetic and not material benefits, compared to monogamous females mating once or mating repeatedly with the same male. Expand
Females benefit from mating with different males in the scorpionfly Panorpa cognata
TLDR
In an experiment designed to rule out any direct nutritional benefit of multiple matings, it is found that polyandrous females that mated with two different males achieved a significantly higher egg-hatching success than monandrous Female of the scorpionfly Panorpa cognata that mates twice with the same male. Expand
Estimating genetic benefits of polyandry from experimental studies: a meta‐analysis
TLDR
A comprehensive meta‐analysis of 232 effect sizes from 46 experimental studies is presented to try to quantify the potential genetic benefits ofpolyandry by controlling fully for the number of matings by females assigned to monandry and polyandry treatments, and raises the intriguing possibility that cryptic, post‐copulatory female choice might be more likely to generate ‘good gene’ or ‘compatible gene” benefits than female choice of mates based on the expression of secondary sexual traits. Expand
Determinants of female fecundity in a simultaneous hermaphrodite: the role of polyandry and food availability
TLDR
The results suggest that female fecundity in M. lignano is primarily determined by the resources available for egg production, and not by the level of polyandry, confirming classic sexual selection theory for simultaneous hermaphrodites. Expand

The evolution of polyandry: multiple mating and female fitness in insects
TLDR
A meta-analysis of 122 experimental studies addressing the direct effects of multiple mating on female fitness in insects shows that females gain directly from multiple matings in terms of increased lifetime offspring production, and supports the existence of an intermediate optimal female mating rate. Expand
BENEFITS OF MULTIPLE MATES IN THE CRICKET GRYLLUS BIMACULATUS
TLDR
The results support the hypothesis that certain males are genetically more compatible with certain females, and that this drives polyandry through differential fertilization success of sperm from more compatible males. Expand

TLDR
It is proposed that the cumulative threat to female reproductive success of genetic incompatibility arising from intragenomic conflict may be an important force driving the evolution of polyandry. Expand
Multiple mating in a water strider: mutual benefits or intersexual conflict?
TLDR
It is concluded that females should theoretically mate approximately every 10th day for maximal survival and fecundity and that multiple matings are not beneficial to females per se, however, females frequently mate several times every day. Expand
Female control : sexual selection by cryptic female choice
TLDR
Cryptic female choice establishes a new bridge between sexual selection theory and reproductive physiology, in particular the physiological effects of male seminal products on female reproductive processes, such as sperm transport, oviposition, and remating. Expand
Rapid evolution of reproductive barriers driven by sexual conflict
TLDR
A simple mathematical model is developed describing coevolutionary dynamics of male and female traits involved in reproduction that shows that continual change in such traits at a constant speed is expected whenever females experience fitness loss from having too many compatible males. Expand
Polyandry and its effect on female reproduction in the green-veined white butterfly (Pieris napi L.)
TLDR
Although the nutrient investment of the first male to mate with a female “subsidizes” the progeny of later-mating males, the male nuptial gift in P. napi clearly qualifies as both paternal investment and mating effort. Expand
Food Quality Controls Sexual Selection in Mormon Crickets by Altering Male Mating Investment
TLDR
The conclusion from this study is that increased sexual selection on females due to such a change in diet is a result of an increase in the relative importance of male parental investment. Expand
NUPTIAL GIFTS AND THE EVOLUTION OF MALE BODY SIZE
TLDR
Direct fecundity selection for larger gifts placed indirect positive selection onmale body size, supporting the hypothesis that nuptial gifts can influence the evolution of male body size in this system. Expand
Courtship feeding increases female reproductive success in bushcrickets
TLDR
Results are reported of an experiment which shows that feeding on the spermatophore enhances the reproductive success of female bushcrickets by increasing the numbers and size of eggs produced. Expand
