- Seasonal and altitudinal effects on glucocorticoid metabolites in a wild primate (Theropithecus gelada)Jacinta C Beehner
Department of Psychology, University of Michigan, Ann Arbor, MI, 48109 USA
Physiol Behav 95:508-14. 2008..Therefore, we suggest a metabolic hypothesis (as opposed to a nutritional hypothesis) to explain this result. However, at the present time, we cannot rule out a behavioral stress hypothesis...
- Infant mortality following male takeovers in wild geladasJacinta C Beehner
Department of Anthropology, University of Michigan, Ann Arbor, Michigan 48109 1043, USA
Am J Primatol 70:1152-9. 2008....
- Testosterone related to age and life-history stages in male baboons and geladasJacinta C Beehner
Department of Psychology, University of Michigan, Ann Arbor, MI 48109 1043, USA
Horm Behav 56:472-80. 2009..For both yellows and chacmas, increases in testosterone production preceded elevations in social dominance rank. We discuss these differences in the context of ecological and behavioral differences exhibited by these taxa...
- Strong and consistent social bonds enhance the longevity of female baboonsJoan B Silk
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]...
- 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...
- 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...
- A Bruce effect in wild geladasEila K Roberts
Department of Psychology, University of Michigan, Ann Arbor, MI 48109, USA
Science 335:1222-5. 2012..Taken together, data support the hypothesis that the Bruce effect can be an adaptive strategy for females...
- Female philopatry and dominance patterns in wild geladasAliza Le Roux
Department of Psychology, University of Michigan, Ann Arbor, 48109, USA
Am J Primatol 73:422-30. 2011..As such, geladas fit the allostatic load model [Goymann & Wingfield, Animal Behaviour 67:591-602, 2004]. Our study confirms the importance of female philopatry in the kin-based Cercopithecine dominance system...
- 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...
- Modifications of a field method for fecal steroid analysis in baboonsJacinta C Beehner
Department of Anthropology, Washington University, St Louis, MO 63130, USA
Physiol Behav 82:269-77. 2004..This method is particularly suited for behavioral research because it permits delays between sample collection and sample processing, thus allowing behavioral observations to continue...
- Reproductive characteristics of wild female Phayre's leaf monkeysAmy Lu
Interdepartmental Doctoral Program in Anthropological Sciences, Stony Brook University, Stony Brook, New York, USA
Am J Primatol 72:1073-81. 2010....
- Phytochemicals and reproductive function in wild female Phayre's leaf monkeys (Trachypithecus phayrei crepusculus)Amy Lu
Interdepartmental Doctoral Program in Anthropological Sciences, Stony Brook University, Circle Rd, Social and Behav Sci Bldg, Stony Brook, NY 11794 4364, USA
Horm Behav 59:28-36. 2011..Although our results support the predicted effects of Vitex on endocrine and reproductive function, future studies with detailed feeding data and chemical analyses of plants are needed to confirm this finding...
- Juggling priorities: female mating tactics in Phayre's leaf monkeysAmy Lu
Interdepartmental Doctoral Program in Anthropological Sciences, Stony Brook University, New York, USA
Am J Primatol 74:471-81. 2012..Although these results suggest that females provide some information on ovulation, they also suggest that females attempt to confuse paternity, perhaps capitalizing on male differences in the ability to detect fertility...
