These episodes are highly aggressive, ending in bloodshed.[3]. ), Alan R. Riss, New York, pp. This typically focuses on the female choosing the best mate rather than the male. In primates, for sons, mothers’ presence at the time of siring increases the reproductive success of sexually mature male muriquis (Brachyteles arachnoides) and bonobos (Pan paniscus) but … Parker, G. A., 1974. [18], In many adult primates, dimorphism in the vocal repertoire can appear in both call production (e.g., calls with a particular set of acoustic traits) and usage (e.g., call frequency and context-specificity) between the sexes. [1][2] However, such sex differences are primarily limited to the anthropoid primates; most of the strepsirrhine primates (lemurs and lorises) and tarsiers are monomorphic.[2][3]. 1994. Hence, males have proportionally larger skeletons compared to females due to their larger body masses. 175–191. Notably in primates, male infanticide can increase the reproductive success of male individuals by accelerating the return of females to fertilizable condition and ensuring that a greater percentages of the individuals’ offspring become the next generation when the male kills the offspring of other rival males . Pope, T. R., 1990. Bouchet H, Pellier A, Blois-Heulin C, Lemasson A. Behav., 32: 23–32. 153–154., doi:10.1086/202026. M. Seyfarth,R. van Noordwijk, M. A., 1985. Another hypothesis suggests that arboreal primates have limitations on their upper body size, given that larger body size could disrupt their usage of terminal branches for locomotion. Ali, S., C. R. Muller, &J. T. Epplen, 1986. In:Female Primates: Studies by Women Primatologists,M. Capturing wild long-tailed macaques.Folia Primatol., 59: 89–104. [20], Ultimate mechanisms for sexual dimorphism in primates explain the evolutionary history and functional significance of the sexual dimorphism expressed among primates. It is rare, yet females in some species are known to have larger canines than males, such as the eastern brown mouse lemur (Microcebus rufus). van Hooff, J. Altmann, S. A., 1962. Reproductive success is defined as an individual's production of offspring per breeding event or lifetime. From a theoretical point of view the existence or absence of this relationship has great implications with respect to the meaning of dominance rank and more general of the social relationships between individuals within social groups. The individuals with these valued characteristics will have the best opportunity of finding a mate. Genet., 48: 824–840. In:Paternity in Primates: Genetic Tests and Theories,R. In extreme cases, males have body sizes that are almost twice as large as those of females, as in some species including gorillas, orangutans, mandrills, hamadryas baboons, and proboscis monkeys. [15] In orangutans, males and females share similarities in facial dimensions and growth in terms of orbits, nasal width, and facial width. 16, 2003, pp. In:Us Against Them: Coalitions and Alliances in Humans and Other Animals,A.

[21] Studies on De Brazza's monkeys (Cercopithecus neglectus), one of the African guenon species, have shown that call rates in adult females (24 call.hr-1) are more than seven times higher than in adult males (2.5call.hr-1). 2006. ————,W. [18] Larger body size has been thought to confer advantages to males in competition for access to females, which is consistent with sexual selection hypothesis. Variation in guenon skulls (II): sexual dimorphism. OCLC 28708379. [23] Males with a larger canine tooth also tend to be competitively superior to males with a smaller canine, which explain a dimorphism in canine size between the sexes. [29], It has been hypothesized that niche divergence between the sexes attributes to the evolution of size dimorphism in primates. The winning male in this combat will be rewarded in mating with the opposite sex primate. F. Dixson, &E. J. Wickings (eds. PubMed Google Scholar, de Ruiter, J.R., van Hooff, J.A.R.A.M.

When they find their mate, these primates typically remain involved in the offspring's life, offering grooming, protection, or entertainment to their offspring. Body size, sperm competition and determinants of reproductive success in male savanna baboons.Evolution, 43: 1507–1521. [3] However, among some species of guenons (Cercopithecus), arboreal blue monkeys (C. mitis) appear to be more sexually dimorphic than terrestrial vervet monkeys (C.

This seasonal phenomenon, known as “male fattening,” is associated with both male-male competition and female choice for larger males. Results. Sexual competition and mate choice. Therefore, the study of primate social behavior has been a focus of primatologists for the last 50 years.
