In support of the Trivers & Willard model of adaptive variation in birth sex ratio, recent research showed that high-ranking female domestic pigs, Sus scrofa, gave birth to a greater proportion of sons than low-ranking females. Differences in maternal nutritional status caused by differential access to food of high- and low-ranking females, or differences in adrenal activity as the result of stress experienced during agonistic encounters are two possible mechanisms underlying these findings… Expand
Sex ratio in litters of domestic pigs (Sus scrofa f. domestica Linnaeus, 1758)
TLDR
It was found that paternal breed and litter size significantly affected the offspring sex ratio (fewer males in larger litters) and maternal month of birth had a significant influence on offspring sex ratios. Expand
Sex ratio in litters of domestic pigs [Sus scrofa f.domestica Linnaeus, 1758]
TLDR
It was found that paternal breed and litter size significantly affected the offspring sex ratio (fewer males in larger litters) and maternal month of birth had a significant influence on offspring sex ratios. Expand
Dominance Rank and Parental Investment in Swine (Sus scrofa domesticus)
Using domestic swine, we tested the general prediction from life history theory that females increase their investment in offspring with increasing age and parity. Because increased investment mayExpand
The Weaker Sex? The Propensity for Male-Biased Piglet Mortality
TLDR
Life history strategies are being displayed by a domestic population of pigs with sows in this study displaying a form of parental optimism by allocating greater resources at birth to males and providing an over-supply of this more vulnerable sex in expectation of sex-biased mortality. Expand
Seasonal Variation in Sex Ratios Provides Developmental Advantages in White-tailed Deer, Odocoileus virginianus
TLDR
It is found that maternal condition did not affect offspring sex ratio in a captive population of White-tailed Deer in Michigan; however, birth date did, and it was found that more males tended to be Born during the second and fourth birthing periods, while more females were born during the first, third and fifth periods.

The sex ratio of a gilt’s birth litter can affect her fitness as a breeding female
TLDR
There is cause to investigate the effect of the birth litter sex ratio of a gilt on her suitability for selection into the breeding herd, and existing evidence of masculinisation in rodents and sheep is covered. Expand
Population density affects sex ratio variation in red deer
TLDR
It is shown that the adaptive relationship between maternal dominance and offspring sex ratio previously demonstrated in red deer, where dominant females produced more males, disappeared at high population density. Expand
Sex Ratio Variation in Iberian Pigs
TLDR
Analysis of sex ratio data of 56,807 piglets coming from 550 boars and 1893 dams and analyses fitting linear and threshold animal models in a Bayesian framework using Gibbs sampling techniques found no trend in sex ratio related to maternal age. Expand
Testing models of adaptive adjustment of secondary sex ratio in domestic swine
Mendl et al. (1995) presented a reanalysis of data from an earlier study (Mendl et al. 1992) in order to determine whether the results reported by Meikle et al. (1993) held for other groups of swine,Expand
Programming of offspring sex ratios by maternal stress in humans: assessment of physiological mechanisms using a comparative approach
  • K. Navara
  • Biology, Medicine
  • Journal of Comparative Physiology B
  • 2010
TLDR
The evidence that stressful events induce sex ratio adjustment in humans is reviewed and the possibility for glucocorticoid mediation ofsex ratio adjustment is discussed and the potential reproductive stages during which stress-induced sex ratio adjusted may occur in humans and other mammals are discussed.

Maternal dominance rank and secondary sex ratio in domestic swine
Abstract Abstract. Maternal dominance rank may influence the reproductive potential of male and female offspring differently. Recent models of adaptive variation in secondary sex ratio (offspring sexExpand
Physiological and reproductive correlates of behavioural strategies in female domestic pigs
TLDR
The strategy used to cope with the social environment may be as important as the success achieved in agonistic interactions, at least in terms of consequences for physiology and reproduction. Expand
Maternal dominance, breeding success and birth sex ratios in red deer
TLDR
It is shown that, in polygynous red deer (Cervus elaphus), dominant mothers produce significantly more sons than subordinates and that maternal rank has a greater effect on the breeding success of males than females. Expand
Sex Ratio Variation in Mammals
TLDR
Valid evidence that sex ratio trends are adaptive must be based on the overall distribution of trends or on cases in which the sex ratio can be shown to vary with the relative fitness of producing sons and daughters. Expand
Differential reproductive success and facultative adjustment of sex ratios among captive female bonnet macaques (Macaca radiata)
TLDR
In a group of captive bonnet macaques housed at the California Primate Research Center, variance in reproductive success among females is primarily due to differences in infant survival, which indicates that the juvenile daughters of low-ranking females are more vulnerable to behaviourally induced mortality than are other immature animals.

Dexamethasone can prevent stress-related litter deficits in the golden hamster.
TLDR
It is suggested that subordinate dams produce smaller litters via selective resorption of males in utero and that the typical adrenal response to stress mediates this response. Expand
Birth sex ratios and social rank in rhesus monkey mothers
TLDR
High ranking rhesus monkey mothers in the authors' captive colony were more likely to give birth to daughters than sons, while the remaining mothers were morelikely to bear sons than daughters, and a mechanism for adjusting birth sex ratios in macaques is suggested. Expand
Role of the Hypothalamic Paraventricular Nucleus in Mediating Stress‐Related Litter Deficits in the Golden Hamster
TLDR
It is suggested that subordinate dams produce smaller litters via selective resorption of males in utero and that the paraventricular nucleus of the hypothalamus may be a relay center for the mediation of this response. Expand
