Abstract

IZAR, Patrícia; RAMOS-DA-SILVA, Eduardo D.; DE-RESENDE, Briseida D.  and  OTTONI, Eduardo B.. A case of infanticide in tufted capuchin monkeys (Cebus nigritus). Mastozool. neotrop. [online]. 2007, vol.14, n.1, pp.73-76. ISSN 0327-9383.

According to behavioural ecology, infanticide by males would be an adaptive reproductive strategy because it allows faster fertilization of the females and reduces investment in unrelated offspring. Critics of this view indicate the lack of evidence of the behaviour for several primate species, hence the relevance of reports of observed infanticide events. Here we report a case of infant killing in a free-ranging group of tufted capuchin monkeys (Cebus nigritus).

Keywords : Infanticide; Male reproductive behaviour; Social structure.
