Playing With Relatives: Genetic Kinship And Play Behavior In Juvenile Tibetan Macaques, Riley Derby

All Master's Theses

This thesis is composed of a journal-ready article and an accompanying appendix containing data and figures. In this thesis, I statistically analyzed the relationship between player age, player sex, genetic kinship and social play duration in juvenile Tibetan macaques.

Chapter I provides a general introduction and addresses current and past literature on the behavior, ecology and play among macaque genera and Tibetan macaques within this study. I review the fitness benefits of play behavior and the influence of kin selection on macaque social life. Additionally, I review the existing literature on Tibetan macaque play and how the current study will …

Salivary Microbiomes Of Indigenous Tsimane Mothers And Infants Are Distinct Despite Frequent Premastication, Cliff S. Han, Melanie Ann Martin, Armand E.K. Dichosa, Ashlynn R. Daughton, Seth Frietze, Hillard Kaplan, Michael D. Gurven, Joe Alcock

Background. Premastication, the transfer of pre-chewed food, is a common infant and young child feeding practice among the Tsimane, forager-horticulturalists living in the Bolivian Amazon. Research conducted primarily with Western populations has shown that infants harbor distinct oral microbiota from their mothers. Premastication, which is less common in these populations, may influence the colonization and maturation of infant oral microbiota, including via transmission of oral pathogens. We collected premasticated food and saliva samples from Tsimane mothers and infants (9-24 months of age) to test for evidence of bacterial transmission in premasticated foods and overlap in maternal and infant salivary …

Kinship Matters: Structures Of Alliance, Indigenous Foragers, And The Austronesian Diaspora, James West Turner

Human Biology

The study of kinship systems has direct relevance for the field of human genetics and the study of microevolution in human populations. Some types of postmarital residence rules—rules requiring a married couple to live with or near relatives of the husband or wife—will have consequences for the distribution of mitochondrial DNA and Y chromosome lineages. Rules that proscribe or encourage marriage with close kin will also have consequences for allele frequency. A preference for marrying at a distance, both socially and geographically, creates alliances that can have survival value for individuals and groups in an environment of periodic or unpredictable …

Dynamical Structure Of A Traditional Amazonian Social Network, Paul L. Hooper, Simon Dedeo, Ann E. Caldwell Hooper, Michael Gurven, Hillard Kaplan

ESI Publications

Reciprocity is a vital feature of social networks, but relatively little is known about its temporal structure or the mechanisms underlying its persistence in real world behavior. In pursuit of these two questions, we study the stationary and dynamical signals of reciprocity in a network of manioc beer (Spanish: chicha; Tsimane’: shocdye’) drinking events in a Tsimane’ village in lowland Bolivia. At the stationary level, our analysis reveals that social exchange within the community is heterogeneously patterned according to kinship and spatial proximity. A positive relationship between the frequencies at which two families host each other, controlling for kinship and …
