infanticide in animals

[9], Males in primate groups often exploit infants to which they are not related in ways that lead to the death of the infant. Trapanese, Cinzia, et al. [1], In the instances of maternal infanticide in tamarins, there were multiple breeding females. Many people regard it as reprehensible to even think about it . " 1–22., doi:10.1007/bf02557698. [1], Resource competition is also a primary motivator in inter-species infanticide, or the killing of infants from one species by another species. [22] In addition to addressing these points, future research into infanticide could reveal the genetic basis for the behavior for non-human primates and answer questions surrounding the curious existence of such a behavior in animals. 1, 1979, pp. Female primates have been observed to actively defend territory from potentially infanticidal females, as seen in chimpanzees. Many primate species have developed counter adaptations to reduce the likelihood of infanticide. Across the animal kingdom, infanticide has been observed in totally disparate mammal species, from dolphins to lions to baboons. In primates, resource competition is a prime motivator for infanticide. Infanticide is a recurring motif in the mythology of ancient Greece. 51, May 2013, doi:10.1073/pnas.1318645110. Maternal infanticide has been reported once in brown mantled tamarins, Saguinus fuscicollis, once in black fronted titis, Callicebus nigrifrons, and four times in mustached tamarins, Saguinus mystax. In these pairs, the males will mate with other females but live exclusively with one female as a socially monogamous pair. “Reproductive Patterns in Eutherian Mammals: Adaptations against Infanticide?” Infanticide by Males and Its Implications, Feb. 2000, pp. Alas, infanticide has gone beyond mere advocacy in the modern world. Since it was first … In this case, there were no clear functions of the infanticide; the reason for infanticide in black-fronted titi monkeys is currently unknown. Edited by MEHERET OURGESSA, student of Joan Slonczewski for BIOL 116 Information in Living Systems, 2019, Kenyon College. [8] In addition to these counter-strategies, males are also thought to display behavior that prevents infanticide when their own offspring is involved. Infanticide, the killing of a young animal by an older animal, is performed by females and males that are unrelated to or are unfamiliar with the pups (see the section on kin recognition in Chapter 13). https://www.encyclopedia.com/.../customs-and-artifacts/infanticide [1], Maternal infanticide, although very rarely observed in non-human primates, has been considered as a way of paternal manipulation to end investment in certain offspring. Ovicide is the analogous destruction of eggs. Similarly, studies of birds, fish, amphibians, and invertebrates demonstrate egg and larval mortality in these species, a phenomenon directly analogous to infanticide in mammals. Interestingly, the frequency and distribution of infanticide seems to suggest that there is a correlation between infanticide risk and social organization in mammals and primates. In an act that seems savage, cold, and downright heartless, helpless young are occasionally killed and even eaten by the very animals that either brought them into the world or helped to nurture them from a very young age. Moore, Jim. In these cases, instances of direct aggression toward inter-specific infants in addition to infanticide have also been observed. Recently, a male Leopard was photographed killing and eating a cub in the Okavango delta, Botswana. Infanticide by males is widespread in mammals and may be the main cause of infant mortality in some populations (1). 1205–1210., doi:10.1098/rspb.2006.0449, https://microbewiki.kenyon.edu/index.php?title=Infanticide_in_Primates&oldid=138102, Pages edited by students of Joan Slonczewski at Kenyon College. Readings Art by Marcel Dzama, Read more. The distribution of male infanticide is closely associated with the absence of seasonal or annual breeding. Infanticide is common among India's lions, but females have developed a clever strategy to keep their cubs safe. 6, 1993, pp. [29], Social pathology: role of social organization, Adaptive counter adaptations to infanticide, CS1 maint: multiple names: authors list (, "Interspecific Infanticide and Infant-Directed Aggression by Spider Monkeys (Ateles hybridus) in a Fragmented Forest in Colombia", "Reproductive failure, possible maternal infanticide, and cannibalism in wild moustached tamarins, Saguinus mystax", "Infanticide and the evolution of pair bonds in nonhuman primates", 10.1002/(sici)1520-6505(1999)7:4<117::aid-evan2>3.0.co;2-o, "Infanticide risk and the evolution of male-female association in primates", "The adaptive value of 'friendships' to female baboons: experimental and observational evidence", "Male infanticide leads to social monogamy in primates", "Do gorilla females join males to avoid infanticide? Variation in social organization and mating systems may have favored or prevented the evolution of infanticide by males in mammalian species.

Agrell, Jep, et al. Infanticide is the killing of young offspring’s by a mature animal of its own species (Wikipedia). Hamai, Miya, et al. [7] Furthermore, infanticide is more likely to occur in mammalian species where there are more males per females in social groups and dominant males obtain a higher share of reproduction in a given season but maintain their dominant position for short periods of time.
