Scent marking strategies of New World primates

Article Abstract:

Recent findings on scent-marking behavior in wild New World primates are reviewed and the findings are used to examine three functional hypotheses namely territoriality, regulation of social and reproductive dominance, and mate attraction. It is found that the patterns of scent marking and the sparse information on responses to scent marks are consistent with a hypothesized function in intrasexual competition and intersexual mate choice.

Individual olfactory signatures in common marmosets (Callithrix jacchus)

Article Abstract:

Behavioral and biochemical aspects of individual odors in a New World primate, the common marmoset (Callithrix jacchus) are systematically assessed. It is found that individual odors may play a key role in regulating both female intrasexual competition and intersexual communication by providing a basis for the assessment of individual quality.

Infanticide and cannibalism in a free-ranging plurally breeding group of common marmosets (Callithrix Jacchus)

Article Abstract:

A detailed study of infanticide and cannibalism in a free-ranging plurally breeding group of Callithrix jacchus shows that infanticide by pregnant female marmosets was prevalent. Cannibalism seemed to be mainly a response to the prompt availability of food.
