Temperature and host species affect nuptial gift size in a seed‐feeding beetle

It is proposed that the effect of nuptial gift size on male fitness is through a reduction in female mating frequency and thus increased paternity for males producing largernuptial gifts.

Resource-dependent nuptial feeding in Panorpa vulgaris: an honest signal for male quality

In the present study, it is able to show that males of P. vulgaris were limited in their production of salivary secretions, and males of nutritionally high status produced more gifts than those ofNutritionally low status.

Food Restriction and Sperm Number in the Water Strider Aquarius remigis.

It is found that males and females in natural populations often contain few or no sperm, and the fitness of both sexes may, at times, be limited by sperm supplies, with food restriction having a drastic effect on sperm numbers in wild males.

Seeking salt: herbivorous prairie insects can be co-limited by macronutrients and sodium.

These results represent the first large-scale manipulation of single micronutrients and macronsutrients in concert, and revealed an herbivore community co-limited by macronut nutrients and Na, which supports an emerging paradigm that Na may be important in limiting herbivor communities.

Male nutritional history affects female fecundity in a male-dimorphic mite: Evidence for a nuptial gift?

Though males of both morphs appeared able to produce nuptial gifts; other factors, like habitat complexity, should be considered to identify fitness benefits of minor over major males to understand why the two morphs coexist.

All that Glisters is not Gold: Sensory Bias, Sexual Conflict and Nuptial Feeding in Insects and Spiders

It is argued that gift composition is more likely to be tailored to increasing the attractiveness of the gift to the female and/or maximizing gift handling time than to suit the female's nutritional needs and that the fecundity-enhancing benefits of nuptial gifts are often questionable and have been over-stated in the literature.

Effects of mating status on copulation investment by male bushcricket Gampsocleis gratiosa (Tettigoniidae, Orthoptera)

Male’s copulation investment, including spermatophore and sperm investment were very high in the Chinese bushcricket Gampsocleis gratiosa, and this finding supported the paternal investment hypothesis, that is, males contributed to their offspring with little attention to their partners.

Nutrition‐ and sex‐dependent utilization of body resources in relation to reproduction in a scorpionfly

It is demonstrated that food availability does influence investment in flight muscle development in scorpionflies, and the build-up of the thoracic muscles was strongly influenced by nutrient availability.

Effects of nutrient limitation on sperm and seminal fluid: a systematic review and meta‐analysis

Interestingly, body size showed considerably stronger condition‐dependent responses compared to ejaculate traits, suggesting that ejaculate trait expression may be strongly canalised to protect important reproductive functions, or that the cost of producing an ejaculate is relatively low.

Size‐dependent effects of larval and adult food availability on reproductive energy allocation in the Yellow Dung Fly

Female selected for small size matured earlier and had relatively larger clutches than large line females (when correcting for body size), in correspondence with greater glycogen investment in reproduction, supporting the relative efficiency hypothesis.

Evidence for the potential ofnuptial gifts to function as either paternal investment, mating effort, or both is reviewed for each form of nuptial feeding in each insect taxon for which sufficient data are available.

Reproductive energetics of the role reversing bushcricket, Kawanaphila nartee (Orthoptera: Tettigoniidae: Zaprochilinae)

An energetic analysis of reproduction for the role reversing bushcricket, Kawanaphila nartee, that supports the contention that this sex role reversal is a consequence of reversal in the pattern of relative reproductive investment.

Food Quality Controls Sexual Selection in Mormon Crickets by Altering Male Mating Investment

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.

COURTSHIP FEEDING AND THE FITNESS OF FEMALE KATYDIDS (ORTHOPTERA: TETTIGONIIDAE)

Katydid males (Requena verticalis) produce spermatophores with a large sperm‐free sperMatophylax, which is eaten by the female after mating, and this male‐produced food substitute for other food in the diet of the female or is it a source of specialized nutrients.

Testing Parental Investment and the Control of Sexual Selection in Katydids: The Operational Sex Ratio

The hypothesis that variation in parental investment controls the numbers of males and females available for mating in katydids is tested and data suggest that male parental investment in the spermatophore increases in its relative importance when diet is low in quality.

Quantification of role reversal in relative parental investment in a bush cricket

The measurement of male and female investment in reproduction for a nutrient-provisioning bush cricket is reported and it is demonstrated that reversals in relative parental investment underlie courtship role reversals seen in this species.

SEXUAL SELECTION AND SEXUAL DIFFERENCES IN MORMON CRICKETS (ORTHOPTERA: TETTIGONIIDAE, ANABRUS SIMPLEX)

  • D. Gwynne

  • 1984
Sexual selection and its consequences at different sites are examined by testing the prediction that sexual selection on females, as estimated by variance in mating success, should be greater at sites where sexual competition among females is observed and detailing the differences in courtship behavior between sites that have apparently resulted from differences in sexual selection.

Experimental reversal of courtship roles in an insect

It is confirmed and shown that an increase in food from a low level results in a change from role-reversal to the typical roles, which supports the theory that variation in relative male parental investment controls sexual differences.

Courtship feeding increases female reproductive success in bushcrickets

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.

There was no correlation between spermatophylax mass and male mating frequency, so that the mechanism by which small–gift males offset their fertilization disadvantage remains unknown.
