Abstract. Pinnipedia contains some of the most spectacular examples of sexual size dimorphism, examples that are therefore frequently used to illustrate the theory of sexual selection. This paper addresses the question of whether a significant relationship between sexual selection and size dimorphism exists in a comparative context. Thus, harem size and body size data gathered from the literature were analysed with independent contrasts analyses. These investigations showed that sexual size… 
Sexual selection explains Rensch's rule of size dimorphism in shorebirds.
Sexual size dimorphism shows a remarkably widespread relationship to body size in the animal kingdom: within lineages, it decreases with size when females are the larger sex, but it increases with
The role of fecundity and sexual selection in the evolution of size and sexual size dimorphism in New World and Old World voles (Rodentia: Arvicolinae)
Evolutionary ecologists dating back to Darwin (1871) have sought to understand why males are larger than females in some species, and why females are the larger sex in others. Although the former is
Sexual selection and sexual size dimorphism in animals
TLDR
Findings suggest that pre-copulatory sexual selection plays a limited role for the evolution of sexual size dimorphism in a broad phylogenetic context.
DISENTANGLING THE CONTRIBUTION OF SEXUAL SELECTION AND ECOLOGY TO THE EVOLUTION OF SIZE DIMORPHISM IN PINNIPEDS
TLDR
This study provides novel insights into the role of sexual selection for the coevolutionary dynamics of SSD and mating system and calls for the inclusion of ecological variables when studying sexual selection and argues for caution when assuming causality between coevolving traits.
SEXUAL SELECTION ACCOUNTS FOR THE GEOGRAPHIC REVERSAL OF SEXUAL SIZE DIMORPHISM IN THE DUNG FLY, SEPSIS PUNCTUM (DIPTERA: SEPSIDAE)
TLDR
The results confirm the differential equilibrium model of SSD in that differences in sexual selection intensity account for the reversal in SSD in European versus North American populations, presumably mediating the ongoing speciation process in S. punctum.
Allometry for Sexual Size Dimorphism: Testing Two Hypotheses for Rensch’s Rule in the Water Strider Aquarius remigis
TLDR
The results support a novel interpretation of the differential‐plasticity hypothesis: that the traits most closely associated with reproductive fitness are “adaptively canalized” among populations of the water strider Aquarius remigis.
Sexual size dimorphism in seabirds: sexual selection, fecundity selection and differential niche‐utilisation
TLDR
It is suggested that seabird SSD is most consistent with the sexual selection hypothesis via the agility of male displays, although further data and tests are required to establish whether different resource utilisation by males and females may also select for SSD.
Sexual selection uncouples the evolution of brain and body size in pinnipeds
TLDR
The results suggest that sexual selection has important effects on the allometric relationships of neural development and that this apparent trade‐off between sexual selection and brain mass is driven by selection for increasing body mass rather than by an actual reduction in male brain size.
Sexual size dimorphism and the strength of sexual selection in mammals and birds
TLDR
There was no consistent relationship between SSD and I, as they were strongly positively related in mammals, but not in birds, which may relate to the form of competition that is found most often in mammals and birds.
Trigoniulid size dimorphism breaks Rensch
TLDR
Millipedes illustrated reversed sexual size dimorphism (SSD) where females were larger than males; and break Rensch’s rule as thisDimorphism increased with body size.

Phylogenetic analyses of primate size evolution: the consequences of sexual selection
TLDR
An independent contrast analysis of male and female size (log weight) showed that these are tightly correlated and that size dimorphism is not a simple allometric function of size, and the directional investigation indicates that the magnitude of change in haplorhine dimorphisms is larger after an increase in sexual selection than after a decrease.

TLDR
Several hypotheses for the evolution of sexual dimorphism in body size are outlined in terms of the types of selection likely to be observed in contemporary studies of populations in a population of Darwin's medium ground finch, Geospiza fortis.
A Comparative Analysis of Allometry for Sexual Size Dimorphism: Assessing Rensch's Rule
TLDR
Rensch's rule is shown to be associated with male-biased SSD, which is consistent with the hypothesis that sexual selection acting on male size drives the evolution of this pattern of allometry.
Sexual-Size Dimorphism: Influence of Mass and Mating Systems in the Most Dimorphic Mammals
TLDR
Characteristics and testing for associations among the most dimorphic mammalian taxa—Macropodidae, Primates, Mustelidae, Pinnipedia, Elephantidae, Ruminantia, found that ruminants with tending and harem mating systems were moreDimorphic than those with territorial polygynous and monogamous mating systems.
Size, dominance and copulatory success in male northern elephant seals, Mirounga angustirostris
TLDR
The hypothesis that male reproductive success in this species is principally determined by dominance rank, which, in turn, is affected by male size is supported, but it is suggested that large size is just one of a number of important factors that affect the outcome of male intra-sexual competition and hence, reproductive success.
Offspring sex ratio in relation to female size in southern elephant seals, Mirounga leonina
TLDR
The results show that smaller females of southern elephant seals vary offspring sex ratio in a way that is consistent with theories on adaptive offspringSex ratio, and a smaller mother with a male foetus may benefit from terminating her pregnancy and allocating the resources she saves to her own growth.
Evidence of equal maternal investment in the sexes in the polygynous and sexually dimorphic grey seal (Halichoerus grypus)
TLDR
It is argued that reports of equal expenditure on the two sexes can be accepted as evidence of equal investment, provided that three assumptions are fulfilled and that the results provide evidence ofequal maternal investment in the sexes in grey seals.

TLDR
Sexual dimorphism may result from natural and/or sexual selection, and systems of mating are often thought to evolve in response to ecological pressures, although mating preferences may be self-reinforcing.
ARE PINNIPEDS FUNCTIONALLY DIFFERENT FROM FISSIPED CARNIVORES? THE IMPORTANCE OF PHYLOGENETIC COMPARATIVE ANALYSES
TLDR
Overall functional differences between pinnipeds and fissipeds appear to have been overstated and may be no greater than those among major fissiped groups, which should lead to a more complete understanding of carnivore biology through more unified comparative tests.
