Several sexual selection theories assume certain benefits of female mate preference. The direct benefit, i.e., the direct contribution from males to their offspring and females, has been well tested empirically. However, the indirect benefit, i.e., the male's genetic contribution to their offspring, has been poorly demonstrated. Female preference for males' carotenoid-based coloration is known in some animals. Since animals must acquire carotenoids through foods, it is often hypothesized that…

Foraging ability in the scorpionfly Panorpa vulgaris: individual differences and heritability
TLDR
The findings suggest that genetic benefits in terms of increased offspring foraging ability might contribute to selection for mating preferences in both sexes.
Relationship Between Algal-Foraging Ability and Expression of Sexually Selected Traits in Male Guppies
TLDR
The results of this study suggest that in male guppies under a carotenoid-limited situation, the allocation ofcarotenoids is directed toward enlargement of the size of the orange spots rather than enhancement of their coloration.
The Relationship between the Algal-foraging Ability and Expression of Sexually Selected Traits in the Male Guppy
In the guppy Poecilia reticulata, males exhibit orange spots on their body and tail, and the orange spot patterns are often criteria of female mate choice. The orange spot coloration of the males is
Algal-searching ability in laboratory experiments reflects orange spot coloration of the male guppy in the wild
TLDR
The hypothesis that female mate preferences for carotenoid-based coloration of males have evolved via indirect benefits such as the high foraging ability of their offspring has been supported.
Does Foraging Behaviour Affect Female Mate Preferences and Pair Formation in Captive Zebra Finches?
TLDR
The findings show that zebra finches can be successfully trained to be foraging specialists and suggest that learned foraging specializations do not affect mate choice or pair formation in the experimental context.
Colourful traits in female birds relate to individual condition, reproductive performance and male-mate preferences: a meta-analytic approach
TLDR
Evidence from empirical studies in birds supports the idea that colourful female ornaments are positively associated with residual mass and immune response, clutch size and male-mate preferences, and hence, colourful traits in female birds likely evolved and are maintained by sexual selection as condition-dependent signals.
Does testosterone affect foraging behavior in male frogs?
TLDR
The results demonstrated a significant effect of testosterone on the hunting behavior of H. arborea, and it was observed that testosterone reduced the orientation latency to virtual prey for supplemented males compared to controls.
Male coloration affects female gestation period and timing of fertilization in the guppy (Poecilia reticulata)
The trade-up hypothesis is a female behavioral strategy related to mating with multiple males. In this hypothesis, females can produce high-quality offspring while avoiding the risk of losing
Energetics of calling in the male treefrog Hyla arborea: when being large means being sexy at low cost
TLDR
Calling energetic costs in an income breeder, Hyla arborea (L), known to produce costly energetic calls, are examined in order to explore the sources of inter-individual variability and highlight the importance of calling energetic cost in income breeding species which have strong consequences on sexual selection processes.
A Sensory Bias Has Triggered the Evolution of Egg-Spots in Cichlid Fishes
TLDR
This work performs mate-choice experiments in the basal haplochromine Pseudocrenilabrus multicolor, which manifests the plesiomorphic character-state of an egg-spot-less anal fin, and tests for color preferences in a phylogenetically representative set of East African cichlids, which uncovered a strong preference for yellow, orange or reddish spots in all Haplochromines tested and, importantly, also in most other species representing more basal lines.

TLDR
More studies taking an interpopulation approach to studying mate preference evolution are needed before the explanatory value of the indicator models can be rigorously assessed.
Algal-diet Enhances Sexual Ornament, Growth And Reproduction in the Guppy
TLDR
Since algae-intake enhanced not only male orange coloration but also growth and reproduction, female guppies may obtain benefits through mate preference for males having brighter coloration and, hence, greater foraging ability for algae.
Carotenoids, parasites, and sexual selection
TLDR
Carotenoids are currently recognized not only as an essential part of a normal diet, but also as free radical scavengers as well as potential prophylactics against cancer and stimulants of the immune system.
Dietary carotenoids and male mating success in the guppy: an environmental component to female choice
TLDR
The results of this study show that females respond to environmentally-induced variation in the expression of a secondary sexual trait and that this has important consequences for male mating success.
Female sticklebacks use male coloration in mate choice and hence avoid parasitized males
TLDR
It is shown that in the three-spined stickleback (Gasterosteus aculeatus) the intensity of male red breeding coloration positively correlates with physical condition, and the females recognize the formerly parasitized males by the lower intensity of theirbreeding coloration.
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.
Carotenoid limitation of sexual coloration along an environmental gradient in guppies
TLDR
It is shown that carotenoid availability in the wild limits the expression of sexual coloration in guppies (Poecilia reticulata), a species in which females prefer males with brighter orange-containing spots, which opens new avenues for testing signal evolution theory.
Courtship as an honest indicator of male parental quality in the bicolor damselfish stegastes partitus
TLDR
It is suggested that observed differences between males in their courtship rates and parental ability may be a result of differences in their energy reserves.
Female mate preference based on male orange spot patterns in the feral guppy Poecilia reticulata in Japan
TLDR
Logistic regression analysis clarified that brighter coloration of male orange spots was the most important factor for female mate preference, and suggests indirect benefits of female preference for male orange spot patterns if the male foraging ability for algae were heritable.
DIRECT AND INDIRECT SEXUAL SELECTION AND QUANTITATIVE GENETICS OF MALE TRAITS IN GUPPIES (POECILIA RETICULATA)
TLDR
It is predicted that indirect selection may have important effects on the evolution of male guppy color patterns and that Attractiveness and mating success are positively correlated at the phenotypic and genetic level.
