    A Bruce effect in wild geladas (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-03-01
    Description: Female rodents are known to terminate pregnancies after exposure to unfamiliar males ("Bruce effect"). Although laboratory support abounds, direct evidence for a Bruce effect under natural conditions is lacking. Here, we report a strong Bruce effect in a wild primate, the gelada (Theropithecus gelada). Female geladas terminate 80% of pregnancies in the weeks after a dominant male is replaced. Further, data on interbirth intervals suggest that pregnancy termination offers fitness benefits for females whose offspring would otherwise be susceptible to infanticide. Taken together, data support the hypothesis that the Bruce effect can be an adaptive strategy for females.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Roberts, Eila K -- Lu, Amy -- Bergman, Thore J -- Beehner, Jacinta C -- New York, N.Y. -- Science. 2012 Mar 9;335(6073):1222-5. doi: 10.1126/science.1213600.

    Hierarchical classification by rank and kinship in baboons (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-11-15
    Description: Humans routinely classify others according to both their individual attributes, such as social status or wealth, and membership in higher order groups, such as families or castes. They also recognize that people's individual attributes may be influenced and regulated by their group affiliations. It is not known whether such rule-governed, hierarchical classifications are specific to humans or might also occur in nonlinguistic species. Here we show that baboons recognize that a dominance hierarchy can be subdivided into family groups. In playback experiments, baboons respond more strongly to call sequences mimicking dominance rank reversals between families than within families, indicating that they classify others simultaneously according to both individual rank and kinship. The selective pressures imposed by complex societies may therefore have favored cognitive skills that constitute an evolutionary precursor to some components of human cognition.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bergman, Thore J -- Beehner, Jacinta C -- Cheney, Dorothy L -- Seyfarth, Robert M -- MH62249/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2003 Nov 14;302(5648):1234-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, University of Pennsylvania, Philadelphia, PA 19104, USA. thore@sas.upenn.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14615544" target="_blank"〉PubMed〈/a〉
