In mammals, males generally are larger than females, though such sexual-size differences have been documented primarily in adults and are relatively poorly known in early life. We studied sexual-size differences in pups of the northern elephant seal (Mirounga angustirostris (Gill, 1866)), which in adulthood is one of the most sexually dimorphic mammals. We studied body size at birth and weaning, at Islas San Benito, Mexico, at the southernmost limit of the species’ breeding range. Males were 10…

Density-dependent effects on reproductive output in a capital breeding carnivore, the northern elephant seal (Mirounga angustirostris)
TLDR
Findings show that the mechanisms controlling reproductive output are conserved across terrestrial and marine systems and vary with population dynamics, an important consideration when assessing the effect of extrinsic changes, such as climate change, on a population.
Multivariate analysis of body weight, morphometric and thermo-physiological traits of indigenous pigs under tropical conditions

Parental investment in southern elephant seals, Mirounga leonina
TLDR
Male and female pups were suckled for the same period, grew at the same rate and were not significantly different in weight at weaning, and mothers' post-partum weight was related to Mother-pup weight inFemale pups but small females often gave birth to large male pups.
Parental investment and the secondary sex ratio in northern elephant seals
TLDR
Data on northern elephant seals bearing on sex ratio theory suggest that parents invest equally in sons and daughters when investment is measured in terms of future reproduction and provide no support for the theory of adaptive shifts in sex ratio.
INVESTMENT IN SONS AND DAUGHTERS BY SOUTHERN ELEPHANT SEALS, MIROUNGA LEONINA, AT MARION ISLAND
TLDR
It is suggested that before discounting maternal investment theories, further studies need to be undertaken to determine the benefits, if any, of size at weaning on long-term survival and reproductive success.
Early determinants of lifetime reproductive success differ between the sexes in red deer
In polygynous, sexually dimorphic species, sexual selection should be stronger in males than in females. Although this prediction extends to the effects of early development on fitness, few studies
Sexual dimorphism across 3 stages of development in polygynous Artiodactyls is not affected by maternal care
TLDR
On the whole, postnatal maternal care seems to have no or even an inverse effect on the evolution of dimorphism, which is apparently not consistent with the assumption of greater maternal investment in male than in female offspring among polygynous mammals.
Variance in male reproductive success and sexual size dimorphism in pinnipeds: testing an assumption of sexual selection theory
TLDR
The theory of evolution by sexual selection for sexual size dimorphism postulates that SSD primarily reflects the adaptation of males and females to their different reproductive roles, and species with male-biased SSD are predicted to have greater variance in male reproductive success than those in which both sexes are similar in size.
DEMOGRAPHY AND BREEDING BIOLOGY OF A SMALL, LOCALIZED POPULATION OF SOUTHERN ELEPHANT SEALS (MIROUNGA LEONINA)
TLDR
Comparison with the few available census data collected prior to this study suggests that the population of southern elephant seals of Sea Lion Island has been stable in the short term (1989-1996), and females produced pups at maximum rate and pup mortality was low.
Northern elephant seal development: The transition from weaning to nutritional independence
TLDR
The 2 1/2-month period from weaning to departure from the rookery was studied in northern elephant seal pups at Año Nuevo Island, California and early sex differences are interpreted as subserving the different adult reproductive strategies of each sex.

TLDR
Little evidence of differential maternal investment is found in male and female grey seal pups during lactation and during the first 13 days of the postweaning fast using longitudinal data obtained on Sable Island, Canada.
