Male adoption in the black and gold howler monkey (Alouatta caraya).

Infant adoption is an association that occurs between an adult individual and a dependent infant and occurs most often when lactating females care for a nutritionally dependent infant that is not her offspring. Adult females are often involved in adoption; while, direct infant care by males occurs in less than 5% of all mammalian species. We report the first record of adoption by wild male adults of Alouatta caraya, a platyrrhine primate species that does not typically participate in parental care.

Parasites and Other Infectious Agents in Non-human Primates of Argentina.

Purpose Of Review: In Argentina, there are five non-human primate (NHP) species: , , , , and . All of them inhabit protected and non-protected areas and face severe threats due anthropization. We aim to summarize the information available about parasites and infectious diseases of these NHPs and suggest further research on primate diseases in Argentina.
