Temperature and host species affect nuptial gift size in a seed‐feeding beetle
TLDR
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. Expand
Resource-dependent nuptial feeding in Panorpa vulgaris: an honest signal for male quality
TLDR
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. Expand
Seeking salt: herbivorous prairie insects can be co-limited by macronutrients and sodium.
TLDR
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. Expand
Male nutritional history affects female fecundity in a male-dimorphic mite: Evidence for a nuptial gift?
TLDR
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. Expand
All that Glisters is not Gold: Sensory Bias, Sexual Conflict and Nuptial Feeding in Insects and Spiders
TLDR
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)
  • Yong Gao, L. Kang
  • Biology, Medicine
  • Science in China Series C: Life Sciences
  • 2006
TLDR
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. Expand
Nutrition‐ and sex‐dependent utilization of body resources in relation to reproduction in a scorpionfly
TLDR
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. Expand
Effects of nutrient limitation on sperm and seminal fluid: a systematic review and meta‐analysis
TLDR
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. Expand
Size‐dependent effects of larval and adult food availability on reproductive energy allocation in the Yellow Dung Fly
TLDR
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. Expand
Mating behavior of a Neotropical arachnid with exclusive paternal care
TLDR
The mating behavior of Iporangaia pustulosa, a Neotropical harvestman with exclusive paternal care, provides evidence of male aggressive rejection of mates and female abandonment of clutches without ovipositing, suggesting that individuals of both sexes may evaluate and select mating partners.

The function of nuptial feeding in insects: a review of empirical studies
TLDR
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. Expand
Reproductive energetics of the role reversing bushcricket, Kawanaphila nartee (Orthoptera: Tettigoniidae: Zaprochilinae)
TLDR
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. 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
COURTSHIP FEEDING AND THE FITNESS OF FEMALE KATYDIDS (ORTHOPTERA: TETTIGONIIDAE)
  • D. Gwynne
  • Biology, Medicine
  • Evolution; international journal of organic evolution
  • 1988
TLDR
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. Expand
Testing Parental Investment and the Control of Sexual Selection in Katydids: The Operational Sex Ratio
TLDR
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. Expand
Quantification of role reversal in relative parental investment in a bush cricket
TLDR
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. Expand
SEXUAL SELECTION AND SEXUAL DIFFERENCES IN MORMON CRICKETS (ORTHOPTERA: TETTIGONIIDAE, ANABRUS SIMPLEX)
  • D. Gwynne
  • Biology, Medicine
  • Evolution; international journal of organic evolution
  • 1984
TLDR
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. Expand
Experimental reversal of courtship roles in an insect
TLDR
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. Expand
Paternal investment in Poecilimon veluchianus bushcrickets: beneficial effects of nuptial feeding on offspring viability
  • K. Reinhold
  • Biology
  • Behavioral Ecology and Sociobiology
  • 1999
TLDR
The dry weight of offspring increased during the first 4 days after spermatophore consumption and thus within the natural remating interval, showing that the sperMatophore has a paternal investment function in addition to its already known sperm protection function. Expand
SPERMATOPHORE SIZE IN BUSHCRICKETS: COMPARATIVE EVIDENCE FOR NUPTIAL GIFTS AS A SPERM PROTECTION DEVICE
  • N. Wedell
  • Biology, Medicine
  • Evolution; international journal of organic evolution
  • 1993
TLDR
Analysis of comparative data of 28 species of bushcrickets reveals that male spermatophore size is positively correlated with female refractory period, which, in turn, correlates with male fertilization success, indicating that the variation in sperMatophore sizes is better explained by a mating‐effort function than a paternal investment function.
