Department of Anthropology, University of California Los Angeles, CA 90095, USA
Curr Biol 20:1359-61. 2010..These data extend our understanding of the adaptive value of social bonds in baboons and complement a growing body of evidence that indicates that social bonds have adaptive value in a range of taxa, from mice to humans [9, 14-19]...
- Testing extraction and storage parameters for a fecal hormone methodDavid J Pappano
Department of Anthropology, University of Michigan, Ann Arbor, 48109, USA
Am J Primatol 72:934-41. 2010..These results suggest that, when utilizing C18 cartridges for fecal steroid storage, researchers should consider several methodological options to optimize hormone preservation and recovery from fecal samples...

- Female testosterone, dominance rank, and aggression in an Ethiopian population of hybrid baboonsJacinta C Beehner
Department of Anthropology, Washington University, St Louis, Missouri, USA
Am J Primatol 67:101-19. 2005..The rank-T relationship may be mediated by supplants or aggression. Finally, we discuss the different interpretations of the hormone-behavior relationship based on within- and across-subject analyses...
- The benefits of social capital: close social bonds among female baboons enhance offspring survivalJoan B Silk
Department of Anthropology, University of California, Los Angeles, CA 90095, USA
Proc Biol Sci 276:3099-104. 2009..These results parallel those from human studies, which show that greater social integration is generally associated with reduced mortality and better physical and mental health, particularly for women...

Department of Ecology and Evolutionary Biology, Princeton University, Princeton, NJ 08544, USA
Horm Behav 49:688-99. 2006..These results demonstrate that our longstanding method for early detection of pregnancies based on observation of external indicators closely matches hormonal identification of pregnancy in wild baboons...
