MATING SYSTEM AND SEXCUL DIMORPHISM IN LARGE TERRESTRIAL, MAMMALIAN HERBIVORES
@article{Jarman1983MATINGSA, title={MATING SYSTEM AND SEXCUL DIMORPHISM IN LARGE TERRESTRIAL, MAMMALIAN HERBIVORES}, author={Peter J. Jarman}, journal={Biological Reviews}, year={1983}, volume={58} }
Sexual dimorphism in mammals is not entirely satisfactorily explained by the models that are advanced to account for it among birds. This may be because species‐specific styles of being dimorphic, and of attaining mature dimorphic state, are not clearly recognized. Mature dimorphism is a syndrome involving body size, appearance and weaponry; each facet and the whole syndrome may have functions in both fighting and signalling. The mature dimorphic stage has to be reached by growth and change…

Patterns of sexual size dimorphism in seabirds of the Southern Hemisphere
- Biology, Environmental Science
- 1993
A review of published data on 99 populations (60 species) of seabirds shows that the degree of sexual size dimorphism varies considerably among species, with males larger than females in some species…
Male and Female Growth in Sexually Dimorphic Species: Harmony, Conflict, or Both?
- Biology
- 2002
Recent studies show that the rapid evolution of sex-specific developmental regulators and modifiers of the otherwise conserved development of the sexes can produce sexual size dimorphism while maintaining the integrity of the developmental program that is shared between males and females.
Ontogeny and sexual dimorphism in booted macaques (Macaca ochreata)
- Biology
- 2005
The results of the investigation suggest that the observed dimorphism in this population is primarily a product of greatly increased growth rates in dentally mature young adult males, in addition to prolonged male growth.
Evolution of sexual segregation in mammalian herbivores: kangaroos as marsupial models
- Environmental Science, Biology
- 2006
Initial results indicate that both size and sex influence segregation in this species, confirming the worth of kangaroos as marsupial models for research into the evolution of sexual segregation.

It is concluded that a phylogenetic comparison of behavior of a wide range of ungulates and other mammals will be needed to solve the enigma of sexual segregation.
Extreme sexual dimorphism in a Miocene hominoid
- Geography, Environmental ScienceNature

Lufengpithecus lufengensis from the late Miocene site of Lufeng, China, was moreDimorphic than the most dimorphic living hominoid, the orangutan, and may have been more dimorphics than any living anthropoid.
Ontogenetic approaches to sexual dimorphism in anthropoids
- Biology
- 1986
It is suggested that an investigation of the ontogenetic bases of sexual dimorphism can provide new insights and information unobtainable from studies concerned only with adult endpoints, and it is demonstrated that although all dimorphic anthropoids appear to be characterized by somebimaturism, the degree varies significantly.
THE EVOLUTION OF SEXUAL SIZE DIMORPHISM IN THE HOUSE FINCH. IV. POPULATION DIVERGENCE IN ONTOGENY
- Biology, Environmental ScienceEvolution; international journal of organic evolution
- 2001
It is suggested that sex-specific expression of phenotypic and genetic variation throughout the ontogeny of house finches can result in different responses to selection between males and females of the same age, and thus produce fast population divergence in the sexual size dimorphism.
THE EVOLUTION OF SEXUAL SIZE DIMORPHISM IN THE HOUSE FINCH. III. DEVELOPMENTAL BASIS
- Biology, Environmental ScienceEvolution; international journal of organic evolution
- 2001
It is suggested that previously documented fast and extensive divergence of house finch populations in sexual size dimorphism may be partially produced by distinct environmental conditions during growth in these populations.
The ontogeny of sexual dimorphism in free-ranging rhesus macaques.
- BiologyAmerican journal of biological anthropology
- 2022
The ontogeny of size dimorphism in rhesus macaques is achieved by bimaturism and a faster male growth rate, as an outcome of sex-specific growth strategies, and these results provide new data for understanding the development and complexities of primateDimorphism.

An adequate mammalian model will have to include another set of factors which oppose the evolution of polygyny by increasing the spacing or mobility of females, and explain why sexual dimorphism has evolved more frequently in large mammals than in small ones.

Mating system theory must mesh with theoretical advances concerning the evolution of territoriality, parental behavior, and animal sociality and by including the appropriate theoretical work from these other areas, an integrated theory of vertebrate mating systems can be developed.
Mammals in Which Females are Larger Than Males
- Biology, Environmental ScienceThe Quarterly Review of Biology

Present knowledge about the species of mammals in which females are larger than males is quite rudimentary and much more information is needed before the authors will be able to speak of the selective pressures accounting for the phenomenon with any reasonable degree of certainty.
The Influence of Habitats on Mating Systems of North American Passerine Birds

Regardless of sex ratio, a polygynous mating is expected to be adaptive for the females as well as for the male, and marshes and prairies are more likely than forests to present the minimum requisite food supply and sufficiently great differences in available food between territories for selection to favor polygyny.

Calculations of rates of reproductive increase for hypothetical lineages of males indicate that these compensating conditions can plausibly explain the evolution of delayed reproduction among male grouse, andoretical considerations suggest that larger size could favor the evolved evolution of deferred reproduction, especially in males, and thus could contribute to the Evolution of sexual bimaturism and polygyny in the larger species of grouse.
Social behaviour, population structure and reproductive potential in impala
- Biology

Impala in southern and eastern Africa differ in the proportion of the year during which adult males are effectively territorial, and consequently in the age at which young males are driven from the female herds, suggesting that this differential mortality is a product of male-imposed social organization.

It is confirmed that large deer species tend to be more polygynous than smaller ones and that intense inter-male competition in large species has led to the development of relatively large antlers.
